    [0001] The present invention relates to the field of surgical instrumentation, in particular surgical tools with removable or interchangeable handles, such as screwdrivers with end-pieces. BACKGROUND . More specifically, the invention relates to a grip handle adapted to receive a removable work tip to form a surgical tool therewith, said grip handle comprising: a main body extending along a longitudinal axis between one end; proximal and a distal end, a receiving orifice formed within the main body and being adapted to receive the sliding work tip, a lever for blocking the sliding of the work tip in the receiving orifice, the lever blocking member rotatably mounted on the main body about an axis of rotation so that it can be tilted between: a locking orientation in which said lever blocks the sliding of the work tip, a release direction in which it allows the sliding of the work tip in the receiving orifice, an elastic pivot through which the locking lever is mo It is rotatable on the main body, the resilient pivot being adapted to automatically return the locking lever to the locking orientation when the latter is in release orientation. The invention also relates to a surgical tool kit comprising a grip handle. The invention further relates to a method of manufacturing a handle handle.
    [0002] The invention finally relates to a manufacturing machine. In the field of surgical instrumentation, there are known modular surgical screwdrivers with interchangeable tips. A surgeon can thus, equipped with a single screwdriver handle and a plurality of screwdriver bits with 5 different functions, to cope with a multitude of surgical situations. For these known modular screwdrivers, it is necessary, when assembling the handle with a given tip, that this assembly is particularly reliable and strong, in particular so that there is no risk of accidental unhitching of the tip, and so that the clearance between the handle and said tip is reduced to the maximum, 10 taking into account the precision required for surgical procedures. Therefore, these known screwdrivers are generally manufactured using parts whose accuracy is high, and which are the subject of a complex and precise assembly to form the handle of a screwdriver having the required qualities, so that they are relatively expensive and difficult to manufacture. Furthermore, the need to clean and sterilize the surgical instrumentation between each operation is likely to deteriorate more or less gradually this assembly, so that the known tool may present a game, or a progressive wear. For known modular screwdrivers, the attachment of a given tip to the removable handle can be performed by actuating a movable part of the handle, for example a button or a rotary lever. The wear of such parts may eventually lead to their actuernent difficult, or on the contrary too flexible, so that the tip change is likely to become difficult over time, which is likely to cause a substantial loss of time during a surgical operation, or on the contrary too loose, so as to increase the risk of accidental disconnection of the tip. The objects assigned to the present invention therefore aim to overcome the various disadvantages listed above and to propose a new handle, a new surgical tool kit, a new manufacturing process and a new manufacturing machine, allowing particularly fast manufacturing and inexpensive to manufacture. Another object of the invention is to provide a new grip handle, a new surgical tool kit, a new manufacturing method and a new manufacturing machine for forming a particularly reliable and robust surgical tool. Another object of the invention is to propose a new grip handle, a new surgical tool kit, a new manufacturing method and a new manufacturing machine, making it possible to form a grip handle whose use is particularly easy. and comfortable. Another object of the invention is to provide a new grip handle, a new surgical tool kit, a new manufacturing process and a new manufacturing machine, to form a grip handle particularly easy to manufacture.

    [0004] Another object of the invention is to provide a new grip handle and a new surgical tool kit to ensure proper sterilization of the surgical environment.

The objects assigned to the invention are also achieved by means of a surgical tool kit comprising a handle according to the invention, as well as at least one removable work tip, preferably two removable work tips. of 20 different function. The objects assigned to the invention are furthermore attained by means of a method of manufacturing a handle according to the invention, the manufacturing method being characterized in that it comprises a single molding step in which during which the gripping handle is made in one piece in its entirety.

    [0006] Other features and advantages of the invention will appear and will appear in more detail on reading the description given below, with reference to the accompanying drawings, given solely by way of illustrative and non-limiting example, in which: FIG. 1 illustrates, in a general perspective view, a gripping handle according to the invention; FIG. 2 represents, in a general perspective view from above, the gripping handle of FIG. 1; FIG. 3 illustrates, in a perspective longitudinal sectional view, the grip handle of Figures 1 and 2, 10 - Figure 4 illustrates, in a partial perspective view, a removable work tip according to the invention, for assembled hearth with the gripping handle of FIGS. 1 to 3 to form a surgical tool, FIGS. 5 and 6 illustrate, in perspective longitudinal sectional views, the gripping handle of FIGS. 1 to 3 associated with FIGS. FIG. 7 shows a detail of the gripping handle of FIGS. 1 to 3; FIG. 8 shows a general perspective view of the working endpiece of FIGS. 4 to 6, 20 - FIGS. 9 and 10 each illustrate a general perspective view of a distinct variant of a working endpiece associable with the grip handle of FIGS. 1 to 7. FIG. 11 illustrates, in a perspective view Another embodiment of a grip handle and a work tip according to the invention are exploded from the side. FIGS. 12 and 13 illustrate, in perspective views, the grip handle and the tip of FIG. Figure 10, the handle having been cut longitudinally.
    [0007] The invention relates to a piece intended to contribute to forming a dismountable and modular surgical tool, and concerns in this case a handle 1 of the surgical tool, a first embodiment of which according to the invention is illustrated in FIGS. 1 to 3, and a second embodiment according to the invention is illustrated in FIGS. 11 to 13. The handle 1, which is in other words a handle or a handle, is designed, according to the invention, to receive a removable work tip 2 to form a surgical tool with the latter, that is to say in this case a surgical instrument particularly suitable for use by a surgeon during of a surgical operation on a patient. Of course, without departing from the scope of the invention, the handle 1 and the surgical tool it helps to form can be used in the context of animal surgery> or for non-surgical uses, for example. example to perform the screwing of a screw in a non-living mechanism.
    [0008] The handle 1 of the invention constitutes an area of the formed surgical tool which can be grasped by the surgeon in a preferred manner, for example with one hand, or two. The work tip 2, in turn, forms the functional part of the tool, and advantageously constitutes a means of action, for example mechanical, on the body of the patient, or on another object, for example a screw or a staple. Advantageously, the surgical instrument thus formed can be used by the surgeon, depending on the work tip 2 received by the handle 1, to perform: - screwing or unscrewing a screw, by example of osteosynthesis, or - the establishment of an osteosynthesis clip, in the body of a patient. To perform the foregoing actions, the surgeon will be able to use several distinct variants of work tips, in particular: a work tip 2 forming a screwdriver bit 2A, that is to say a screwdriver shaft (such as as illustrated in FIG. 8), a work tip 2 forming a pin insertion guide 2B (as illustrated in FIG. 9), a work tip 2 forming a 2C drilling guide for placing a staple (as shown in Figure 10), a work tip 2 forming a scalpel blade (not shown). The gripping handle 1, for its part, advantageously forms a handle of 5 screwdrivers, and / or a support sleeve for setting up pins and / or drill guide, and / or a scalpel handle. Preferably, the handle 1 is multifunctional and versatile, and is adapted to receive work tips 2 whose functions are varied and distinct. The handle 1 of the invention comprises a main body 3 extending along a longitudinal axis XX 'between a proximal end 7 and a distal end 6. The main body 3 advantageously has a generally axial or elongated shape , preferably a general shape of revolution around the longitudinal axis X-X ', so as to be adapted to be handled by the surgeon ergonomically and safely.
    [0009] The main body 3 preferably has the shape of a conventional screwdriver handle, as illustrated for example in FIGS. 1 to 3, but may alternatively be in the form of a knob or a handle, as illustrated by FIG. example in Figures 11 to 13. For the preferred example illustrated in FIGS. 1 to 3, preferably, the proximal end 7 is intended to form the back of the surgical tool, and more specifically the end of the tool which is intended to be turned in the direction of the surgeon. The distal end 6 will be advantageously intended to be turned towards the patient. The surgical tool formed will thus preferably be a straight axial tool.
    [0010] In the second preferential example illustrated in FIGS. 11 to 13, the gripping handle 1 may serve to form, for example, an angled or "T" tool, the working bit 2 then extending perpendicularly to the handle 1, so that the distal end 6 and the proximal end 7 form a right and left portion 3024833 8 of the handle 1 of the tool, which is for example intended to be arranged transversely relative to the patient In the preferential case or the handle 1 is intended to form the handle of a screwdriver, it will be intended to be rotated about its longitudinal axis XX '5 to perform the screwing or unscrewing of a screw through 2. In this preferred case, or in any other case, the handle 1 has a distal portion whose general shape is that of an ellipsoid of revolution, whose diameter of revolution is coaxial with the longitudinal axis X-X '. Such a shape is particularly adapted to grip for rotation around the longitudinal axis X-X ', as illustrated in the figures. The gripping handle 1 may preferably have a non-slip outer surface. In particular, the handle 1 may have grooves 5, for example parallel to each other, formed in the main body 3 along the latter, in a longitudinal direction. These grooves 5 advantageously have the triple function of improving grip adhesion, lightening the main body 3 in order to save weight and material, and to allow molding to be performed on said main body 3. In fact, the grooves 5 are preferentially deep enough to ensure that the main body 3, while having an ergonomic outer contour, for example of the shape of a conventional screwdriver handle, is substantially devoid of areas where the material is very thick, in order to minimize shrinkage at demolding. In addition, the grooves 5 are arranged in the main body 3 so that the latter can be demolded during its manufacture, around a joint plane Pi including for example the longitudinal axis X-X '. For this purpose, the grooves 5 are advantageously oriented in planes orthogonal to said joint plane Pi, 25 parallel to the longitudinal axis X-X ', and are for example undercut relative to the latter. According to the invention, the handle 1 also comprises a receiving orifice 4 formed within the main body 3 and being designed to receive the work tip 2 to slide. The gripping handle 1 thus includes a receiving orifice 4 in which the working endpiece 2 can be assembled to the gripping handle 1. The shape, and especially the section of the receiving orifice 4, is advantageously shaped to correspond with the work tip 2, so that the handle 1 forms the female part of the surgical tool, the work tip 2 forming the male part. In the case of FIGS. 1 to 3, the receiving orifice 4 is advantageously formed inside the main body 3 from the distal end 6 so as to form an axial surgical tool. In this case, the receiving orifice 4 is preferably designed to receive the work tip 2 sliding along the longitudinal axis X-X ', so as to form an axial surgical tool. The grip 1 is designed so that the working tip 2, being inserted into the receiving hole 4, can translate within the latter in the direction of the length of the main body, in a limited or no race . The receiving orifice 4 thus forms a rail, or a sliding guide of the work tip 2 along the longitudinal axis X-X '. Preferably, as illustrated in FIGS. 1 to 3, the receiving orifice 4 is formed within the main body 3 from the distal end 6, for example aligned with the longitudinal axis X-X '. Of course, there is nothing to prevent that the receiving orifice 4 is formed from the lateral surface of the main body 3, where off-axis with respect to the longitudinal axis X-X '. The receiving orifice 4 optionally passes through the main body 3 from one end to the other, for example from the distal end 6 to the proximal end 7, which makes it possible in particular to facilitate the manufacture of the handle I. Alternatively, in the preferred case shown for example in Figures 11 to 13, the receiving orifice 4 is formed within the main body 3, so as to open from the outer surface thereof, between the distal end 6 and 25 the proximal end 7. The receiving orifice 4 is thus preferably located on an intermediate portion of the handle 1, and is preferably located midway, in a median manner, between the proximal end 7 and the end distal 6.
    [0011] The receiving orifice 4 is advantageously designed, in this case, to receive the sliding workpiece 2 along an orthogonal axis ZZ orthogonal to the longitudinal axis XX 'so as to form a surgical tool in accordance with FIG. "T". Preferably, the receiving orifice 4 has a congruent shape with the outside contour of the working endpiece 2, and makes it possible to block the workpiece 2 in rotation with respect to said gripping handle 1 respectively around the outside. XX 'longitudinal axis for the preferred embodiment of Figures 1 to 3, or around the orthogonal axis ZZ' for the preferred embodiment of Figures 11 to 13, while allowing the sliding of said work tip 2 relative to the handle 1 according to the same axis. To enable the workpiece 2 to be rotated by the gripping handle 1 about the longitudinal axis XX, or the orthogonal axis Z-Z ', respectively, the receiving opening 4 has, on at least a portion of its depth, a shape which is advantageously not a form of revolution respectively around the longitudinal axis X-X ', or the orthogonal axis ZZ. Preferably, in particular in the preferred case shown in FIGS. 1 to 3, the receiving orifice 4 has a section whose shape makes it possible to lock the work tip 2 in rotation with respect to said grip sleeve 1 around the longitudinal axis X-X ', while permitting the sliding of said work tip 2 with respect to the handle 1 along the longitudinal axis X-X'. The receiving orifice 4 thus appreciably allows, according to this configuration, only one degree of freedom to the work tip 2 when the latter is inserted within said receiving orifice 4. For this purpose in particular, the The receiving orifice 4 has at least one main longitudinal groove 8 extending over at least a portion of the length of said receiving orifice 4, the main longitudinal groove 8 being designed to cooperate with a main longitudinal fin 8A of the mouthpiece. Work 2 to secure in rotation said work tip 2 relative to said handle 1 about the longitudinal axis XX '(as illustrated in Figures 1 to 3). Thus, when the formed surgical tool is rotated about the longitudinal axis XX 'of the handle 1 of the surgical tool 30, the main longitudinal groove 8 mechanically rotates the main longitudinal fin 8A. which is of complementary shape, coming into contact with the latter. The main longitudinal groove 8 extends for example radially to the longitudinal axis X-X ', along a plane which is both orthogonal to the joint plane Pi and both comprises the longitudinal axis X- X '. Preferably, the receiving orifice 4 also has two longitudinal longitudinal grooves 9, 10 arranged symmetrically with respect to a plane formed by the main longitudinal groove 8, the longitudinal longitudinal grooves 9, 10 being designed to cooperate each with a longitudinal fin appendix 9A, 10A of the working end piece 2 for securing in rotation said work piece 2 with respect to said handle 1 about the longitudinal axis X-X '. The plane formed by the main longitudinal groove 8 advantageously including the longitudinal axis XX 'and being advantageously orthogonal to the joint plane Pi, the auxiliary fins 9A, 10A thus preferably extend along said joint plane Pi, as illustrated to the figures, to form a receiving hole 4 in "T". Alternatively, the longitudinal grooves 8, 9, 10 of the receiving orifice 4 may for example be arranged in "Y". The receiving orifice 4 may also have more longitudinal fins, to have a cross shape, or star. The use of main and auxiliary grooves can also be applied to the preferred case 20 shown in FIGS. 11 to 13, these grooves then being orthogonal along the orthogonal axis ZZ 'and not longitudinal along the longitudinal axis XX' (not shown in the figures). Likewise, for the alternative variant of the invention illustrated for example in FIGS. 11 to 13, the receiving orifice 4 has a section whose shape makes it possible to lock the workpiece 2 in rotation with respect to said handle 1 around the orthogonal axis Z-Z ', while permitting the sliding of said work tip 2 relative to the handle 1 along the orthogonal axis Zr. The receiving orifice 4 thus appreciably allows, according to this configuration, only one degree of freedom to the work tip 2 when the latter is inserted within said receiving orifice 4.
    [0012] Preferably, the receiving orifice 4 forms a female socket 25, for example a hexagonal recess, which is designed to cooperate with a corresponding male form 26 of the work tip 2 in order to secure in rotating said work tip 2 relative to said handle 1 around the orthogonal axis ZZ '(as shown in FIGS. 11 to 13), or respectively around the longitudinal axis XX' according to the variant envisaged (which not shown in the figures).
    [0013] Whatever the shape of the receiving orifice 4, the working tip 2 has a corresponding adapted shape, so that it can be inserted into said receiving orifice 4. These preferred forms of the receiving orifice 4 advantageously make it possible to reduce the clearance required for the smooth sliding of the work tip 2 within said receiving orifice 4, so that the assembly of said work tip 2 with the handle 1 is particularly precise and reliable. For the preferred case shown in Figures 1 to 3, the receiving orifice 4 thus having three longitudinal grooves 8, 9, 10 or more, it is therefore possible to insert a work tip 2 having a lower number of corresponding longitudinal fins 15. In particular, it is possible to advantageously envisage the insertion in the receiving orifice 4 of a work tip 2 having only two or a single longitudinal fin. By way of example, it will be possible to insert workpieces 2 of the type shown in FIGS. 9 and 10, each including only the two longitudinal fins 9A, 10A, and being devoid of a main fin 8A. , Especially in the case where such workpieces 2 are intended to form with the handle a surgical tool which is not particularly intended to be rotated about the longitudinal axis X-X '. Such working endpieces advantageously form respectively the spindle positioning guide 2B and the piercing guide 2C, for example for the implementation of a staple. In this preferred case, the working bit 2, and in particular the longitudinal fins 9A appended, 10A may be provided with adhesion means 11 designed so that, said work tip 2 being introduced into the receiving orifice 4 , the adhesion means 11 make it possible to block or at least harden the sliding of said work tip 2 within said receiving orifice 4, so as to secure the grip handle 1 with said work tip 2. Such means of adhesion 11 may be formed for example by gadroons, or pins, arranged on the edge or the edge of the longitudinal fins 9A, 10A, as illustrated in FIGS. 9 and 10. Regardless of the variant of FIG. the invention envisaged, preferably, the receiving orifice 4 has a sliding end stop designed to stop in translation the work tip 2 along the longitudinal axis X-X ', or respectively the long d e the orthogonal axis Z-Z ', when the latter is inserted into said receiving orifice 4 at a determined depth. The sliding end stop is for example formed by the contour of the inlet 12 of the receiving orifice 4, against which lugs 13 or pins of the work tip 2 (as shown in FIG. 8), for example arranged on at least one of, or both, longitudinal wings 9A, 10A are intended to abut. Alternatively, the end stop is formed by the bottom of the receiving orifice 4 (not shown). This preferred configuration makes it possible to further reinforce the precision of assembly of the work tip 2 within the receiving orifice 4.
    [0014] The handle 1 of the invention comprises a locking lever 14 for sliding the work tip 2 in the receiving orifice 4. The locking lever 14 allows the surgeon to block or unblock the sliding of the working tip in the receiving orifice 4, for example with the aid of a simple pressure on said lever 14. By eliminating at least the degree of freedom in translation along the longitudinal axis XX 'of the work tip 2 in relation to the main body 3 of the handle 1, the locking lever 14 secures said work tip 2 with said handle 1, so as to form the surgical tool. It also makes it possible to release said degree of freedom in translation from the working endpiece 2 with respect to the main body 3 in order to release said working endpiece 2 from the gripping handle 1. Advantageously, the presence of the operating lever blocking 14 makes it possible to achieve a very slender receiving orifice 4, with a minimum clearance, so as to make the insertion of the work tip 2 particularly easy. The longitudinal force exerted on the work tip 2 is then advantageously taken up totally or in part by the locking lever 14, optionally associated with the slide end of the travel 3024 833 14 described above. The placement and the holding in position of the work tip 2 is thus particularly precise and solid, so that the formed surgical tool is quite reliable while being practical. According to the invention, the locking lever 14 is rotatably mounted on the main body 35 about an axis of rotation YY 'so that it can be tilted between: o a locking orientation in which said lever blocks the sliding of the work tip 2 (shown in Figure 1), o a release direction in which it allows the sliding of the work tip 2 in the receiving orifice 4.
    [0015] The locking lever 14 of the invention is designed to adopt a rocking motion about the axis of rotation Y-Y ', so that, for example, a downward motion on one of its ends allows to move the other of its ends upwards, and vice versa, during a rotation about the axis of rotation YY '. Preferably, the locking lever 14 extends between a locking end 17 of the working endpiece 2 and a manual operating end 18 of said locking lever 14. Thus, preferably, an action on the part of the surgeon on the operating end 18 can tilt the locking lever 14, such movement being transmitted by the body of said locking lever 14 at the locking end 17. Preferably, the axis of rotation YY 'is thus located between the locking end 17 and said operating end 18. Preferably, a pressure on the operating end 18 makes it possible to tilt the locking lever 14 towards its release direction. Alternatively, of course, without departing from the scope of the invention, raising the operating end 18 makes it possible to tilt the locking lever 14 towards its release orientation.
    [0016] Preferably, from the locking end 17 to the operating end 18, the lever is disposed substantially parallel to the longitudinal axis X-X, in locking orientation or in release orientation. The axis of rotation YY 'is advantageously substantially orthogonal (as illustrated in FIGS. 11 to 13), or substantially ortho-radial (as illustrated in FIGS. 1 to 3) with respect to the longitudinal axis X-X' .
    [0017] By "ortho-radial" is meant that the axis of rotation Y-Y 'is substantially coaxial with a tangent of a circle itself coaxial with the longitudinal axis X-X'. The locking lever 14 can thus be actuated by the surgeon when the latter rotates said locking lever 14, for example a few degrees or tens of degrees, about the axis of rotation YY '. In the preferred case of FIGS. 11 to 13, the axis of rotation YY 'is advantageously parallel to the orthogonal axis Z-Z', so that the three axes X-X ', YY' and ZZ 'are geometrically In accordance with the invention, the release orientation of the lever 14 makes it possible to release the sliding of the working end-piece 2, particularly in the case where the sliding latter was in the locked state by said lever 14 In release orientation, the working tip 2 can slide perfectly along the longitudinal axis X-X ', or along the orthogonal axis Z-Z' respectively, in the receiving orifice 4, and to be freely extracted, or on the contrary to be freely inserted. In blocking orientation, a portion or an end of the lever preferably comes into contact with the work tip 2 or a portion thereof, in order to block the sliding of said work tip 2 in the receiving orifice 4. Preferably, the blocking of the sliding of the working piece 2 by the locking lever 14 can only be performed if the working piece 2 is inserted into the receiving orifice until it is substantially in axial abutment against the limit stop, or at least 20 until it is in a position close to the position in which it is at the end of travel. This position "end of stroke" advantageously corresponds to the relative position of the work tip 2 and the main body 3 when the surgical tool is assembled. The release or blocking of the work tip 2 is therefore particularly easy, insofar as a simple pressure on said, or setting in motion of said locking lever 14 allows the release and / or blocking of said mouthpiece. Work 2 within the gripping handle 1. Preferably, as shown in the figures, the gripping handle 1 comprises a groove 19 formed in the main body 3 and extending longitudinally, the locking lever 14 being disposed within said groove 19 so as not to exceed the outer contour of the main body 3 over at least one third of the length of said locking lever 14 when the latter is in blocking orientation. By "outer contour" is meant the virtual contour of the main body 3, as if the latter is devoid of any notch, cavity, groove, or groove. Preferably, the outer contour of the main body 3 has the shape of an ellipsoid of revolution around the longitudinal axis X-X '. The groove 19 preferably forms a groove, for example radial and longitudinal with respect to the longitudinal axis X-X 'of the main body 3, and within which all or part of the locking lever 14 is embedded, or integrated. According to this preferred configuration, the locking lever 14 does not protrude or protrude slightly from the main body 3, so that it does not interfere with the ergonomics of the grip by the surgeon of the main body 3. Preferably, in blocking orientation, the locking lever 14 follows the outer curve of the contour of the groove 19, and therefore of the main body 3, for example from the locking end 17 to half, two thirds, or three quarter of the length of said locking lever 14 towards the operating end 18. This fact, on the contrary, the latter protrudes from the main body 3 so as to be accessible to be operated. The handle 1 advantageously comprises an operating concavity 20 formed in the main body 3, within which the operating end 18 of the locking lever 14 protrudes. Thus, the locking lever 14 protrudes from the concavity 20 maneuver 20, preferably in the vicinity of its operating end 18, in order to be easily maneuvered. Preferably, the locking lever 14 is sufficiently protruding from the operating concavity 20 not to exceed the outer contour of the main body 3. Such a design makes the handle 1 perfectly comfortable and ergonomic, while allowing a maneuver The gripping handle 1 of the invention also comprises an elastic pivot 15, 16 through which the locking lever 14 is rotatably mounted on the main body 3, the resilient pivot 15, 16 being designed to automatically return the locking lever 14 in the locking orientation when the latter is in the release direction. The elastic pivot 15, 16 combines the functions of: pivoting connection of the locking lever 14 relative to the main body 3 around the axis of rotation YY ', means for automatically returning the locking lever 14 to its blocking orientation.
    [0018] In this way, when the working tip 2 is in the proper position within the receiving hole 4, and is in particular in the vicinity of the end position, the locking lever 14 is oriented it itself in the locking position to block the sliding of the work tip 2. The fastening of the work tip 2 with the handle 1 is thus quite easy.
    [0019] Preferably, the locking lever 14 returning of itself in blocking orientation, it is in blocking orientation in the absence of action or maneuver of the surgeon on said locking lever 14. Preferably, the tip 2 and the locking lever 14 are shaped so that the insertion of the working tip 2 into the receiving hole 4 causes a change in the orientation of the locking lever 14 towards its release position, until that the work tip 2 is inserted sufficiently deep into the receiving orifice 4, to a so-called "end-of-travel" position in which the locking lever 14 toggles by itself under the action of elastic pivot 15, 16 towards its blocking orientation, and therefore automatically blocks the sliding of the work tip 2 without action or maneuver of the surgeon on said locking lever 14. Preferably, the locking lever 14 is provided with a drive slope 23 of said lock sink 14 towards its release direction, said driving slope 23 being for this purpose designed to be driven by a reciprocal lifting slope 24 of the work tip 2 during the insertion of said work tip 2 (such As illustrated in Figures 5 to 7). The lifting slope 24 is preferably formed by an end edge of the main longitudinal fin 8A of the work tip (as shown for example in Figure 4). To release the work tip 2, the surgeon preferably operates the locking lever 14 so as to direct it towards its release orientation, which releases the work tip 2, and allows it to slide out of the receiving orifice 4.
    [0020] Thus, the assembly and disassembly of the surgical tool formed by the handle 1 of the invention is particularly fast and easy. According to an important feature of the invention, the main body 3, the locking lever 14 and the resilient pivot 15, 16 are made of material with each other so as to form a single piece. In this case> the handle 1 of the invention constitutes a single piece, advantageously made in a single material worked to obtain both the main body 3, the locking lever 14 and the elastic pivot 15, 16. The handle 1 of the invention is not, in particular, the result of the assembly of several parts. This design allows the gripping handle 1 of the invention to be particularly easy to manufacture, for example manufactured by molding a preform of the gripping handle 1, and machining said preform of the handle 1 to form to both the main body 3, the resilient pivot 15, 16 and the locking lever 14. Preferably, the handle 1 is manufactured using a single molding operation, i.e. that the material for forming the handle 1 as a whole is inserted into a mold, for example by injection or casting, and that the handle is formed and finished at the opening of the mold. Thus, the gripping handle 1 advantageously requires for its manufacture no machining complementary to the molding.
    [0021] The material used for such a manufacture must be chosen to be both elastic enough for the formation of the elastic pivot 15, 16, and at the same time sufficiently strong so that the main body 3 allows a solid and safe gripping of the tool surgical. In addition, the material used is preferably moldable or injectable to allow the manufacture of the handle 1 according to the preceding modalities. Finally, the material must advantageously be sterilized, insofar as the handle handle will be used for surgical purposes. Preferably, therefore, the grip 1 is made in one piece of a single piece of polymer material, for example PEEK, such a material advantageously fulfilling all the above criteria. Alternatively, a metal alloy of the stainless steel type or a composite material may be used.
    [0022] In this way, since the polymers are generally relatively inexpensive to implement, it is conceivable to make a handle 1 disposable and / or recyclable, and / or disposable. The handle may for example be provided in the form of a sterilized kit, the kit also comprising disposable workpieces 2 or not, the kit being usable for a given surgical operation, and being intended to be discarded or recycled at the end of said surgical operation. In this way the good sterilization of the surgical environment is ensured. Preferably, the axis of rotation YY 'is situated between the locking end 17 and said operating end 18 so as to be closer to the locking end 17 than to the operating end 18. with a pair of equal rotation around the axis of rotation YY 'of the locking lever 14, it is necessary to perform a maneuver with less force on the operating end 18 than on the locking end 17, to modify the orientation of said locking lever 14 against the elasticity of the elastic pivot 15, 16. The operation of the locking lever 14 is thus particularly easy, and its blocking nature of the work tip 2 is so particularly strong. Preferably, the axis of rotation Y-Y 'is located about one-third of the length of the locking lever 14 from the locking end 17, as illustrated in the figures. Advantageously, the elastic pivot 15, 16 connects the locking lever 14 to at least 20 a wall of the groove 19. More specifically, as shown in the figures, the locking lever 14 advantageously forms a blade extending from substantially orthogonal to the axis of rotation Y-Y ', the resilient pivot 15, 16 being formed by two substantially semi-cylindrical pivot elements 15, 16 whose height axis is formed by the axis of rotation Y- Y ', said pivot members being disposed on either side of the locking lever 14 to connect the latter to two distinct walls of the groove 19. The latter are preferably parallel and opposite, the locking lever 14 being disposed between them two. The locking lever 14 is thus mounted on the main body 3 symmetrically, which is particularly strong and durable. The resilient pivot 15, 16 thus advantageously has a flush shape with respect to the joint plane Pj so that it can be produced simultaneously with the main body and the locking lever 14 by molding. The receiving orifice 4 is preferably recessed in a direction coaxial with the longitudinal axis X-X 'so as to be modeled by a drawer of a slide mold during the molding operation. Preferably, the main longitudinal groove 8 of the receiving orifice 45 is aligned substantially in the extension of the locking lever 14, the main longitudinal fin 8A being designed to come into contact with said locking lever 14, and particularly with the locking end 17 to allow the blocking of said work tip 2 by said locking lever 14. The main longitudinal groove 8> and / or the locking lever 14, and / or the grooves 5, and / or the groove 19 are thus preferably oriented along parallel planes between them, which are themselves orthogonal to the Pi joint plane, which facilitates the manufacture of the handle 1, and in particular possible molding steps. Preferably, the locking lever 14 is designed to mechanically block the sliding of the work tip 2 by combination of shapes of the locking lever 14 and the work tip 2. Such a configuration thus allows a maintenance in precise position of the work tip 2 within the receiving hole 4. However, it is possible to envisage that the locking lever 14 simply blocks the work tip 2 by adhesion. Advantageously, the elastic pivot 15, 16 provides a return force of the locking lever 14 towards its locking orientation when said locking lever 14 is moved away from its locking orientation, the locking force applying to the work tip 2 via the locking lever 14, the latter being provided with a return surface 27 of the return force (as shown in Figure 7) allowing the locking lever 14 to press the work tip 2 in the direction of the longitudinal axis XX 'under the action of the elastic pivot 15, 16 against an end stop, when said locking lever 14 mechanically blocks the sliding of said work tip 2 Preferably, the deflection surface 27 is adapted to interact with a receiving surface 28 of the work tip 2, which are adapted to be brought into contact with one another so as to slide one of them. against each other. The return surface 27 and the receiving surface 28 are preferably substantially parallel to each other when the work tip 2 is inserted into the receiving orifice 4, and are preferably inclined with respect to the axis. longitudinal X-X ', with respect to the joint plane Pi, around for example an ortho-radial axis to the longitudinal axis X-X'.
    [0023] The sliding support of the deflection surface 27 against the receiving surface 28 makes it possible to transmit to the working endpiece 2 a component coaxial with the longitudinal axis XX 'of the restoring force provided by the elastic pivot 15, 16, so as to be able to press said work tip 2 against an end stop under the action of said elastic pivot 15, 16 transmitted via said locking lever 14.
    [0024] The end stop is advantageously an axial abutment, making it possible to stop the working end piece 2 in translation along the longitudinal axis X-X ', as described above. Preferably, as shown in the figures, the locking lever 14 is provided with a locking striker 21 designed to be inserted, or to insert itself, into a locking notch 22 of the work tip 2 to block the sliding of the latter when the locking lever 14 is in blocking orientation. Preferably, the locking notch 22 is carried by the main longitudinal fin 8A. The locking striker 21 advantageously also forms the drive slope 23 of the locking lever 14 in rotation towards its release direction. Of course, the reverse arrangement 20 can advantageously be adopted, in which the work tip 2 comprises a locking striker and the grip handle comprises a corresponding locking notch. Preferably, as shown in FIG. 7, a portion of the outer contour of the locking striker 21, in particular the locking end 17 of the locking lever 14, forms the return surface 27. Likewise, a portion of the outer contour of the locking notch 22 forms the receiving surface 27. In addition, the locking striker 21 advantageously comprises a retaining surface 29, intended to come into contact with a reciprocal surface 30 of the work tip. 2, so as to mechanically lock the sliding of said work tip 2 out of the receiving orifice 4.
    [0025] Preferably, the deflection surface 27 is also the drive slope 23. Thus, the locking striker 21 and the locking notch 22 advantageously have a reciprocal and complementary shape. The invention also relates as such to a surgical tool kit comprising a grip handle 1 as described above, as well as at least one removable work tip 2, preferably two removable work tips 2 of different function. By "different function" is meant that the two workpieces 2 make it possible to form with the handle 1 respectively a first surgical tool and a second surgical tool whose function will be different from the first surgical tool, that is to say say that said surgical tools are intended to perform distinct and non-similar actions, or to interact differently with the operating environment and with the body of the patient. For example, work tips 2 of different function can screw or unscrew respectively a first screw 15 with a first head impression, and a second screw with a second head impression different from the first head impression. Preferably, the work tips 2 correspond to those described above. Advantageously, according to the foregoing, one of the work bits 2 is formed by a screwdriver bit 2A, another of the work bits 2 being formed by a piercing guide 20, for example for place of osteosynthesis staples and / or pins, or a guide for placing pins 2B. The surgical tool kit advantageously comprises the pins, the screws, the staples, and additional work tips 2, for example: at least a second screwdriver work tip 2, which makes it possible to screw a screw whose footprint or the nominal diameter differs from the screw that can be screwed by the screwdriver bit 2A, and / or - a work tip 2 gripping staples, and / or - a work tip 2 impaction staples in a patient's bone, and / or - a work tip 2 for impinging the pins in a patient's bone, and / or - a work tip 2 for drilling holes in a patient's bone. The surgical tool kit is preferably disposable and / or disposable, and is preferably contained in a package under sterilized atmosphere.
    [0026] The invention further relates as such to a method of manufacturing a handle 1 as described above. According to the invention, the manufacturing method comprises a single molding step during which the gripping handle 1 is made in one piece in its entirety. In other words, the manufacturing method of the invention makes it possible to produce the gripping handle 1 as described above, in a single operation, without any other finishing operation of the machining or other type. The material to be molded during the manufacturing process is preferably a polymer. Preferably, the manufacture of the handle takes place in the following manner: the material intended to form the handle 1 is poured or poured or injected into a manufacturing machine formed by a mold, for example a mold drawers, so that the material is modeled by the manufacturing machine, in this case by the mold, - the mold is opened once the shaped material, the latter forming the handle 1 in its final form. The invention finally relates as such to a manufacturing machine (not shown in the figures) of a handle 1 as described above, and to implement the manufacturing method described above. Preferably, the manufacturing machine of the invention comprises a mold 25 comprising a first mold cavity, a second mold cavity and at least a first tray, which are intended to form a closed space in which a mold cavity 302 4 83 3 24 material intended to form the handle 1 is intended to be cast. Preferably, when the material is poured into the mold: the first mold cavity and the second mold cavity are designed to co-pattern the material to form, at least in part, the main body 3, the locking lever 14 and the resilient pivot 15, 16, the first drawer being designed to provide the receiving port 4 within the main body 3. The manufacturing machine of the invention thus advantageously forms a mold with drawers.
    [0027] Within the meaning of the invention, "modeling" means giving a shape by molding to the material. The first impression is advantageously designed to model the portion of the grip 1 rising from the joint plane Pi in a first direction of space, the second imprint being designed to shape the handle portion of the handle 1 raising from the joint plane Pi in a second direction of the space opposite to said first direction of the space. Preferably, the manufacturing machine also comprises a second drawer designed to, with the first drawer, arrange the receiving orifice 4 within the main body 3, the first drawer serving to provide a first portion of the receiving orifice. 4 extending from the distal end 6, the second slide serving to provide a second portion of the receiving orifice 4 extending from the proximal end 7. When the mold is closed, it is that is to say, when the first impression is brought against the second impression, the drawers are preferably designed to extend along the joint plane Pi so as to provide the receiving orifice 4. The machine for manufacturing the The invention thus makes it possible to produce the handle 1 of the invention in a single molding operation, preferably without additional machining, so that the handle 1 of the invention is removed. easy, fast, and inexpensive to manufacture.
