    [0001] The invention relates to a handle for a medical device, with an inner part which has means for attachment to the medical device, and with an outer part which has a locking element which, for the removable attachment of the outer part on the inner part, can be brought into locking engagement with a complementary element of the inner part. In the fixed state, the inner part is at least partially covered by the outer part on the surfaces of the inner part which are not turned towards the medical apparatus, and an actuating element, the manual operation of which permits to release the lock, is further provided on the outside. In the state of the art, a large number of handles are known for medical devices which must mainly allow a targeted movement of medical devices. In addition to the handling of the corresponding handles, an essential feature of the handles for medical devices is that they must be easy to clean, disinfect and / or sterilize. In particular, the handles that are used in the surgical field and are within reach of the surgeon must be sterilized at the end of an operation. In order to enable this, such handles are generally made removable, so that they can be removed and sterilized in a simple manner in a sterilizer. In this context, there are medical devices such as surgical lamps which are at least partially in the sterile operating area and which, during an operation, are grasped by the surgeon and brought into the position respectively necessary. At the end of an operation, it is necessary to sterilize the handles of the corresponding devices. In particular for operating lamps, sterilization is effected by the fact that the corresponding handles are removed and sterilized in a sterilizer. In order to be able to remove the handle as simply as possible, it often has a locking mechanism with an actuating element through which a spring loaded engagement member can be actuated, and thus the lock be released. An essential feature of the configuration of the corresponding actuating elements as well as the release mechanisms connected thereto is that they should preferably be operated with one hand so that a user can simple way remove a corresponding handle from the lamp. In this context, document DE 10 2010 034 562 A1 discloses an operating lamp which has a handle subassembly in the middle of the lower housing part. The handle sub-assembly described essentially has a fixed handle, in particular locked in rotation, of a size that is suitable for easy grasping with one hand or at least the fingers by the operating doctor, in order to ability to rotate the operating lamp in conjunction with the swivel arm system in the desired position as needed. For use of the handle subassembly in sterile area, it is important that at least the handle be sterile. To achieve this, a particular configuration of the handle sub-assembly described provides that the gripping element of the handle is designed as a spare part which, following the actuation of the actuating element of a locking mechanism, can be removed from the operating lamp and sterilized in a simple manner. All known handles for medical devices, in particular for examination or operating lamps, have the disadvantage that either gaps are present in the region of the actuating mechanism, which are difficult to clean, disinfect or sterilize. or elements of the actuating mechanism, in particular corresponding spring-loaded buttons, are provided in the sterile region of a handle subassembly and should be partly sterilized separately. Other undesirable properties of handles made removable on medical devices concern excessively high clearance and unfavorable mounting conditions, in particular insofar as mounting is possible only in given angular positions, as well as providing for a gripping face that is not ergonomically shaped. Starting from the known solutions in the state of the art as well as the problems described above, the object of the invention is to perfect a handle for a medical device so that it is possible in a simple manner and without exerting a it is important to remove the element to be sterilized from the handle assembly, mainly in order to obtain a relatively simple sterilization of the gripping face. The attachment of an element to be sterilized in a corresponding manner must also be possible in a simple manner and preferably with one hand. Likewise, care must be taken to provide an ergonomic shape of the gripping face, and furthermore to ensure that the handle can be cleaned, especially disinfected, easily and durably also in the mounted state on the medical device. The invention achieves the purpose described above by a handle for a medical device of the type mentioned in the introduction, which is characterized in that the actuating element is made in one piece with the interlocking element. and the outer portion such that the actuating member accomplishes with the engagement member movement relative to the complementary member during unlocking, and in that the engagement member is connected to the outer part with spring effect. According to advantageous embodiments of the invention, which will be described in detail in the description which follows, with reference in part to the drawings: the inner part and the outer part have a plastic material at least on their outer faces; in the locked state, a force may be transmitted from the outer portion to the inner portion through the engagement member and the complementary member; the inner portion has on one outer face at least one threaded tooth which can be brought into engagement with a complementary threaded tooth disposed internally on the outer portion; the at least one threaded tooth and the complementary threaded tooth are made in the manner of a right-hand thread; the at least one threaded tooth and the complementary threaded tooth are arranged and arranged in such a way that the outer part and the inner part can be brought at a minimum distance from each other insofar as they are united in a predefined angular range before the execution of the rotation movement; the actuating element has a spring arm; the actuating element has a gripping face; the outer part covers at least almost completely the inner part in the locked state; the at least one threaded tooth and the complementary threaded tooth are arranged and arranged so that the inner part and the outer part can be joined in such a way that locking is possible by the shortest path. Finally, the present invention also relates to the preferential use of such a handle on an examination lamp and / or an operating lamp. According to the invention, a handle for a medical device, with an inner part which has means for attachment to the medical device and with an outer part, which has a locking element which, for the removable attachment of the outer part on the inner part, can be brought into locking engagement with a complementary element of the inner part, and which, in the fixed state, covers the inner part at least partially on the surfaces thereof which are not not turned towards the medical device, knowing that an actuating element whose manual actuation allows to release the interlocking connection is provided on the outside, such a handle so has been perfected so that the element d The actuation is carried out in one piece with the interlocking element and the outer part so that the actuating element accomplishes with the elongated element. ment latching movement relative to the complementary element during unlocking. The important point in the technical solution according to the invention is therefore that a handle subassembly is provided, consisting of an outer part and an inner part, where the outer part is made in one piece, in particular, a continuous and closed outer surface which does not have interstices or the like is provided. Such an outer part may be preferably manufactured as a plastic element, in particular by injection molding. The shape given here is chosen so that on the one hand an ergonomically shaped gripping face is provided, and on the other hand the outer surface has the least possible of notches and other complicated geometries, so that element can be cleaned in a simple and reliable way. With the aid of a handle made according to the invention, there is provided in particular an outer portion in one piece, which can be sterilized. In addition, both the inner part and the outer part are of ergonomic shape, so that both the fixing and the release of the outer part are possible in a simple way, and on the other hand that the manipulation The handle, including the movement of the medical device, can be performed without exerting a significant force. Since the inner part is almost completely covered by the outer part and, advantageously, only a small gap remains between the medical device and the outer part, it is ensured that the probability of contact with non-sterile areas of the handle during an operation and when locking and unlocking the outer part is weak. Advantageously, the threading of the outer portion on the inner portion is independent of the angular position or at least insensitive to incorrect angular positions. In this context, it is fundamentally conceivable to realize the outer part in the form of a reusable element, to be sterilized, or in the form of a single-use element, which is eliminated as a result of its use. Since the outer part is in the form of a single-use element, it is particularly advantageous for this element to have only a small wall thickness, as can be done preferably with a manufacturing in the form of a single-use element. blow molded element. It can further be envisaged that a thin-walled outer portion made as a disposable member is attached to the inner portion directly or via a suitable adapter member. According to a particular embodiment of the invention, it is provided that the inner part and / or the outer part have a plastic material at least on their outer faces. In a particularly preferred manner, both the inner portion and the outer portion are made of a suitable plastics material. According to particular additional configurations of the invention, it is preferable for the inner part to use a polyamide, in particular PA12-GB30, and for the outer part a polyetherimide (PEI). In any case, the choice of materials should be such that the surfaces can be cleaned in an easy manner and that the outer part can be sterilized several times without causing a persistent deterioration of this material. element. The lock according to the invention is constructed so that, in the locked state, a force can be transmitted from the outer part to the inner part via the interlocking element and the complementary element. . The interlocking element and the complementary element are preferably wedge-shaped and each have a chamfered sliding face, these faces coming into mutual contact and being displaced relative to each other during the process of locking. In the locked state, the interlocking element and the complementary element have respective abutment faces which, in the locked state, apply against each other and, in a locked state, Partly allow a low play clearance of the outer portion with the inner portion, and on the other hand prevent an unexpected release of the lock. In a preferred manner, the interlocking element of the outer part and the complementary element of the inner part are made in such a way that, without the actuation of the actuating mechanism to unlock, it is necessary for the unlocking a release force that far exceeds the force that can be exerted manually on the handle. According to a particular embodiment, the inner portion 10 has on one outer face at least one thread that can be brought into engagement with a complementary thread disposed internally on the outer portion. Preferably, these two threads are made in the form of a thread on the right. By thread in the sense of this embodiment is also meant an individual flank of a thread, which can be brought into engagement on a surface with a complementary thread flank, made in a corresponding manner. According to a preferred embodiment, a respective threaded tooth is provided on the inner part as on the outer part, teeth which can be brought into mutual engagement, so that by means of a rotational movement, it is possible to produce a displacement of the outer part relative to the inner part, so that the outer part can thus be brought into a locked position relative to the inner part. Various geometries are generally suitable for the configuration of the threaded tooth. Preferably, the threading tooth 25 and / or the thread have a trapezoidal profile, sawtooth or triangular tooth shape. In a preferred manner, a screwing movement around and along a fixed axis is made during the locking of the outer portion relative to the inner portion. At the same time, a longitudinal displacement of the outer part with respect to the inner part is obtained. As thread types, it is possible to consider triangular threads, trapezoidal threads, round threads and sawtooth threads. When threaded teeth with a trapezoidal or sawtooth profile are used, relatively little friction is achieved between the outer and inner portions during the rotational movement and the related locking process. According to a particular embodiment of the invention, it can be envisaged that the locking element is arranged on a spring arm. The spring arm here is formed integrally with the outer part and preferably performs a relative movement with respect to the inner part during the locking process. In the locked state, the spring arm is in a slightly prestressed state. However, for both the unlocking and locking, the spring arm is biased so that it performs a movement in order to successfully execute the corresponding process. Preferably, the spring arm has the actuating element which advantageously has a suitable gripping face. Preferably, such a gripping face is modified as to its surface properties with respect to the surrounding surface and / or has a hollow for the fingers or the thumb. According to a particular embodiment, the surface is polished in the region of the gripping face, while the remainder of the surface of the inner portion is matted. Of course, one can basically also consider an exactly opposite execution of surfaces. A user can thus operate in a particularly ergonomic manner the actuating element provided on the spring arm to lock or unlock the locking mechanism, so as to be able, in a simple and quick way, to detach the outer part. of the inner part or fix it on the latter. According to a particularly suitable embodiment, it is only necessary to actuate the actuating element to detach the outer part of the inner part, while the engagement during the locking takes place automatically. Similarly, it is ensured that it is possible to maneuver the actuating element with one hand and detach the inner part of the outer part.
    [0002] A preferred embodiment of the outer portion further provides that, in the fixed state, the outer portion covers the inner portion on all surfaces that are not facing the medical apparatus. The outer surface of the outer portion can thus be used in the sterile area of an operating room for example, and disinfected and / or sterilized in a simple manner at the end of an operation. To secure the handle to the medical device, the inner portion preferably has through-holes which are suitable for receiving screws or rivets. With such fixing means, the inner part is fixedly connected to the medical device and remains permanently on the latter. Only the outer part, which is fastened to the inner part by means of a suitable locking mechanism, can, if necessary, be removed from the inner part and therefore also from the medical device. In addition to a handle for a medical device, the invention also relates to the use of a handle made according to the invention for an examination lamp and / or an operating lamp. In a preferred manner, the handle is then disposed below the lamp in the illuminated area centrally. The user can thus in a simple way, using the handle, move the lamp to the position it needs. It is fundamentally irrelevant whether the lamp is placed directly on the ground or attached to a suspended apparatus or support arm. The handle is, by means of the inner part, connected to the examination or operating lamp in such a fixed manner that the user can, if necessary, move the lamp even without the arms of a suspension furthermore provided. What is particularly important for this purpose is, on the one hand, that the locking element is made such that an unexpected release of the lock is reliably prevented in the locked state, and on the other hand that the clearance between the interlocking element and the complementary element is limited to a minimum. In particular, the handle is, by the cooperation of the interlocking element and the other fastening means such as the threading described above, connected to the inner part so that the forces and torques can be transmitted from a satisfactory way in all spatial directions. The invention will now be described in more detail, without limiting the general inventive concept, using exemplary embodiments and with reference to the figures, in which: FIG. 1 represents an operating lamp with a handle 30 arranged centrally; Figure 2 is an assembled representation, in perspective, of a handle with an outer portion and an inner portion; Figure 3 provides perspective representations of an interior portion of a handle; Figure 4 provides perspective representations of an outer portion of a handle; Figure 5 shows the attachment and locking of the outer portion on the inner portion of a handle, and Figure 6 shows the unlocking and removal of the outer portion of the inner portion of a handle.
    [0003] Figure 1 shows a medical apparatus 2 in the form of a surgical lamp, as it is usually attached to moving to a pivoting system of suspended arm. The operating lamp 2 here has a light source 10, which is arranged in the lamp housing 9 and which is constructed in such a way that the light rays emitted are directed through a light output face 11. on the field of work. A handle 1 made according to the invention is provided centrally in the middle of the light exit face 11 and allows a user, in particular a doctor, to bring to the desired position the operating lamp 2 and possibly a system suspended arm connected to it. For this adjustment, it is fundamentally important, on the one hand that it can be performed without exerting a large force, and on the other hand that the lamp 2 remains in the position set by the user. The operating lamp 2 shown in FIG. 1 is used in the sterile area of an operating theater and is operated, if necessary, by a person involved in the operation. The gripping face 12 of the handle 1 is therefore in the sterile zone and must be at least disinfected following an operation, and sterilized after a given cycle of operations, in particular at the end of a day of operations. To this end, the handle 1 is made such that by operating an actuating member 8, a lock is released and the outer portion 4 of the handle 1 can be detached from an inner portion 3 fixed to the lamp operative 2 proper, and thus deposited. We will now explain in more detail the various elements of the handle 1 made according to the invention, which has essentially an inner portion 3 fixed to the operating lamp 2 and a removable outer portion 4. Figure 2 shows a handle 1 for a medical device 2 in a perspective view, knowing that the handle 1 is most conveniently suited for use with an operating lamp. The handle 1 has an inner part 3 which is connected via a locking mechanism 27 to an outer part 4, knowing that the inner part 3 and the outer part 4 are made of a plastic material. The outer part 4 is made in one piece so that it covers at least almost completely the inner part 3 and only a small gap 13 remains present between the outer part 4 and the inner part 3 in mounted and locked state. The outer portion 4 has a disk-like base member 14 with a contact-protecting collar 15 which surrounds the inner portion 3. A body 16, at least approximately cylindrical, having a gripping face 12, follows. The body 16 having the gripping face 12 is ergonomically shaped so as to ensure easy grip and good holding in the hand of the user. An actuating member 8 in the form of a spring arm which has an engaging member 5 is provided on the base member 14 in the region of the contact protection collar 15. By pressing the actuating element 8, the latter is moved towards the inner part 3 and first releases the locking between the outer part 4 and the inner part 3. Then, the outer part 4 can be completely removed from the inner portion 3 by a counterclockwise rotational movement. In a preferred manner, by actuating the actuating element 8 with the thumb, it is possible to release and remove the outer part 4 with one hand. As soon as the outer part 4 is locked, with the help of the element 5 which engages in a complementary element 7 in the inner portion 3, the rotational movement of the outer portion 4 relative to the inner portion 3 is blocked in both directions of rotation. The outer part 4 is locked with a small clearance relative to the inner part 3, thus allowing a simple and precise operation of the medical device 2 connected to the handle 1. The important thing is the one-piece construction of the outer part 4 with the locking element 5 provided thereon, which has a suitable engagement profile 23, and with the actuating element or actuating element 8. Thanks to the closed surface of the part 4 with its collar 15 protection against contact, provides a closed surface that can be cleaned, disinfected and / or sterilized in a simple and reliable manner. Thanks to the locking mechanism 27, it is possible here in a relatively simple manner to remove the outer part 4 of the inner part 3 and make it available for a sterilization operation. The outer part 4 can be detached by pressing on the actuating element 8 of the spring arm type provided with the locking element 5 on which is provided a hollow for the thumb or fingers, of so that the lock 27 is released. Figure 3 provides two perspective representations of the inner portion 3 of a handle 1 made according to the invention for a medical device 2, knowing that such a handle 1 is particularly suitable for attachment to a surgical lamp. Figure 3a here is a perspective view of most of the outer face of the inner portion 3, while Figure 3b provides a view of a portion of the inner face. The inner part 3 is made of plastic and has a base member 17 made of the disk type, from which a body 18 extends. Three through holes 6 are provided as fixing means in the region of the element. base 17 of the disc 15 type or plate, piercing in which can be introduced screws for fixing the inner part on a medical device, in particular an examination lamp or operation. In addition, there is provided on the disk-like base member 17, in the region of the outer periphery 20, a lug 19 having a complementary nib-like element 7 for receiving the locking element 5. of the outer part 4. During the locking of the outer part 4 with the inner part 3, this complementary element 7 is brought into engagement with the locking element 5 of the outer part 4, and these two elements 5, 7 are moved relative to each other so that the engagement member 5 is locked within the complementary member 7 by its wedge-shaped receiving portion. To release the lock, the locking element 5 of the outer part 4 is moved relative to the complementary element 7 of the inner part 3 so that the two elements 7, 5 are no longer in mutual engagement. A release of the lock without having actively actuated the actuating element 8 in order to move the locking element 5 relative to the complementary element 7 is only possible by exerting a relatively high force, which can not be exercised manually with the usual maneuver. The outer part 4 is thus reliably prevented from coming off unexpectedly from the inner part 3. Furthermore, on the outer part of the base element 14 of the disk or plate type three threading teeth 21 which form On the inner part 3 an external thread which can be brought into engagement with threaded teeth 22, made in a corresponding manner, an internal thread provided on the outer part 4, so that the outer part 4, by means of a rotational movement with respect to the inner part 3, a screwing movement, and that the outer part 4 is then moved relative to the inner part 3 in the longitudinal direction of the two parts. The inner part 3 thus has three short threading teeth 21 on the periphery, in which complementary threading teeth 22 of the outer part 4 engage simultaneously, so that the outer part 4 is threaded onto the inner part 3. and rotated clockwise with respect to the inner portion 3. While the threaded teeth 21, 22 are brought into mutual engagement, the engagement member 5 disposed on the periphery 15 of the outer portion 4 returns by its cuneiform engagement profile 23 in the complementary profile 24 of the complementary element 7 disposed on the inner portion 3 and finally locks thereon, knowing that the locking is performed in a clearly audible manner for the user. Once the locking is complete, the rotational movement of the outer portion 4 relative to the inner portion 3 is blocked in both directions. For the automatic locking, the elasticity of the material of the outer part 4 is used, in that the wedge-shaped engagement profile 23 slides during the locking process along a complementary execution ramp of the complementary profile. , that the locking element 5 is thus moved in a position taut with respect to the inner part 3 and that finally, upon reaching the locked position, it audibly engages in the position again slightly prestressed. However, Figure 4 provides two perspective representations of an outer portion 4 of a handle 1 made according to the invention for a medical device. FIG. 4a here represents the outer face located in the sterile zone, in particular the gripping face, while FIG. 4b provides a representation of the inner face of the base element 14 also made of the disk type, with the collar 15. protection against the contacts and the threaded teeth 22 provided therein, which form an internal thread. The outer part 4 is made substantially complementary to the inner part 3, knowing that it is also a part made of plastic. The gripping face 12 of the outer portion 4 is ergonomically shaped so that the grip of the handle 1 is easy and the user's hand is reliably avoided. even when moving the medical device 2 connected to the handle 1. In addition, there is provided on the outer periphery of the outer part 4 an actuating element 8 in the form of a spring-loaded lug, which 10 has an engagement element 5 having an engagement profile 23 which, during locking, is brought into engagement with the complementary profile 24 of the inner portion 3. The actuating element 8 in the form of a spring leg or arm is here made resilient, so that the spring-arm tab is moved during the locking process and finally audibly engages in the locked position. In the locked position, the spring arm is relaxed or only slightly prestressed. For the automatic interlocking connection, the elasticity of the material of the outer part 4 is used here, in that the connection 20 between the base element 14 and the actuating element 8 provided with the element 5 of engagement of the outer portion is in the form of a spring arm. During the locking process, this spring arm has a slight preload with respect to the engaged position. As soon as the spring arm is in the engaged state, it is again only slightly prestressed. It is only to release the lock that the actuating element 8 in the form of a spring arm is again tensioned by exerting a pressure, and that the engagement profile 23 of the locking element 5 on the outer part 4 thus moves relative to the complementary profile 24 of the complementary element 7 on the inner part 3, so that the locking element 5 can finally be removed from the complementary element by rotating the outer part 4. In the mounted state, the outer portion 4 is supported on the one hand by the inner face of the disk-like base member 14 against the outer face of the base member 17 of the disc type of the Inner part 3. The threading teeth 22 provided on the inner side of the base element 14 of the disc type of the outer part are here in engagement with the complementary threading teeth 21 on the outer face. the lower part of the base member 17 of the disc type of the inner part 3. In doing so, the threading teeth 21, 22 grip the faces of the discs one against the other almost without play. On the other hand, the body 18 of the inner part 35 rests at the lower end in the inner contour of the body 16 of the outer part 4. The locking element 5, which is on the actuating element 8 in form spring arm, has on the surface of the actuating element 8 which is opposed to the engagement profile 23 a recess for the thumb or fingers, to allow a preferential actuation of the actuating element equipped with the locking element 5. It is here possible for a user to grasp the handle 1 with one hand and to press, for example, with the thumb on the actuating element of the genus paw, so as to release intentionally the lock. The spring arm is then stretched again so that the engagement profile 23 is released from the complementary profile 24 of the inner portion 3, and the outer portion 4 can finally be released from the inner portion 3 by a rotation in the anticlockwise. Unlocking and removing the outer part 4 of the inner part 3 is thus possible in a simple way, even with one hand. Figure 5 shows the threading and locking of the outer portion 4 on the inner portion 3 at different times of the locking process. Figure 5a shows the handle at a time when the outer portion 4 and the inner portion 3 are further separated from each other.
    [0004] Subsequently, the outer part 4 is first threaded by its body 16 onto the body 18 of the inner part 3. In order to prevent the outer part 4 from being put in place at an incorrect angle, with which the teeth 21, 22 would then enter into mutual engagement, but the engagement mechanism would not take one of the threaded teeth on the inner portion 3 and the complementary threading tooth on the outer portion 4 is made larger than the other two threading teeth. This ensures that, if the outer portion 4 is placed at an incorrect angle with respect to the inner portion 3 and rotated clockwise, the threaded teeth 21, 22 do not engage. because the enlarged net slides on the outer face of the disc of the inner part 3. If we continue to rotate the outer part in the clockwise direction, it abuts by a lug or nose 26 formed on 3035187 - 15 - one of the threading teeth 22 against one of the threading teeth 21 of the inner part, so that the rotation is blocked without the handle engages. Only if the outer part is set up in an angular range in which the two enlarged threaded teeth are brought closer together can the outer part 4 arrive closer to the inner part 3, by the fact that the threading tooth enlarged slips along a bias of the inner portion 3, so that the threading teeth can achieve mutual engagement while continuing to rotate the outer portion 4.
    [0005] In addition, in order to help the user to find the correct position of the outer part 4 with respect to the inner part 3, it is provided at least on the outer part 4 or the inner part 3, and preferably on both parts, a mark 25 which indicates to the user how he should set up the outer part 4 on the inner part 3 3, to obtain from there the engagement position by the path most short possible by rotating clockwise. During the rotational movement of the outer part 4 with respect to the inner part 3, as shown in FIG. 5b, the threading teeth 22 of the outer part 4 come into contact with the threading teeth 21 of the inner part 3 , and the engagement profile 23 provided on the periphery of the outer part 4 comes into engagement with the complementary profile 24 on the inner part 3. The rotational movement in the clockwise direction is continued until, as shown 5c, the engagement profile 23 of the outer part 4 audibly engages in the complementary profile 24 of the inner part 3. Once the locking process is completed, the rotational movement is blocked in both meaning. For the automatic locking, the elasticity of the material of the outer part is used, knowing that the connection between the base element 14 of the outer part 4 and the actuating element 8 provided with the element 5 which has an engagement profile 23 is formed as a spring arm. During the locking process, the latter has a preload with respect to the engaged position. Figure 6 shows in three views the unlocking process. In Fig. 6a, the handle 1 is first shown in a state in which the outer portion 4 is locked with the inner portion 3, so that the engagement profile 23 of the outer portion 4 is found in low play engagement with the complementary profile 24 of the complementary element 7 on the inner part. By exerting pressure, here with the thumb recess on the top, on the actuating element 8 which is in the form of a spring arm, the locking element 5 is moved and its engagement profile 23 unlocked relative to the complementary profile 24. At the same time, the outer portion 4 is rotated counterclockwise, as shown in Figure 6b. This rotation is continued until the threaded teeth 21, 22 of the outer part 4 and the inner part 3 are no longer engaged, so that the outer part 4 can be removed from the inner part 3. The outer part 4 and the inner part 3 are now, as shown in FIG. 6c, again in a state separated from each other, so that the outer part 4 can now be brought in case of need to a sterilization process. The technical solution according to the invention, which essentially comprises a handle for a medical device which has an outer part and an inner part that can be locked to one another, knowing that the outer part is made of a the sole part, is distinguished by the fact that, on the one hand, the outer part can be installed on the inner part and removed from the inner part in a particularly simple manner, and on the other hand the outer part can, because of of its configuration, be cleaned, disinfected and / or sterilized reliably. The outer part 4 and the inner part 3 are thus preferably each made of a single piece of plastic, which has advantages in terms of both the necessary hygiene and the costs of manufacturing a handle. 1. In addition, the lock presented is simple to operate, and the lock can be perceived by the user by a clearly audible noise, especially a click. In the locked state, a reliable transmission of the forces of the outer part 4 to the inner part 3 is guaranteed. With regard to possible transverse movements when the handle 1 is actuated, reliable support is obtained by means of the threading teeth 21, 22, the disc faces 14, 17 and the bodies 16, 18 of the outer part 4 and the inner part 3.
    [0006] In the direction of rotation of the handle 1, the locking mechanism 27 acts with a large lever arm relative to the axis of the handle. In addition, the elasticity of the actuating element 8 preferably in the form of a spring arm has the effect, by a torsional deformation, that the locking element 5 is placed by its profile. 23, during the biasing biasing in the counterclockwise direction, biased so that opposes spontaneous disengagement. In addition, the outer part 4 and the actuating element 8 are configured so that the outer part 4 covers at least almost completely the inner part 3, so that an involuntary contact of the inner part 3 or other regions, for example an operative lamp, is unlikely.
    [0007] Unlocking takes place with a small force, preferably by pressing with the thumb on a depression provided for this purpose on the actuating element 8 and by effortless rotation of a small amount of angularity in the counterclockwise direction. In doing so, only the outer portion 4 is contacted. The preferred actuating element 8 is preferably sufficiently remote from the gripping face 12 itself for an unexpected unlocking to be reliably or reliably prevented. still be improbable. In addition to the ergonomics of the outer part 4, the inner part 3 is also made of a corresponding ergonomic shape, so that it can also be used for the positioning of the medical device. For example, the operating staff can pre-position the operative lamp with this non-sterile inner portion, and then set up the usually sterile outer portion.
