Invention Patent Descriptive Report for: SURGICAL INSTRUMENT.
TECHNICAL AREA
The invention relates to a surgical instrument with the characteristics of the generic term of claim 1, as well as a recovery instrument for the surgical instrument and a drilling template for the surgical instrument.
TECHNICAL STATUS
Staples or staples are used to connect bone segments, for example in foot and hand surgeries according to Weil, Scarf, Austin, Chevron and Cheil and in several other surgical applications. The clamps serve to fix and / or help in the compression of bone parts and remain in the body in most cases. Incidentally, these staples and / or staples are small implants and difficult to attach due to their shape. With state-of-the-art recovery instruments, staples and / or staples are only applicable slowly. Another problem during staple and / or staple implantation is that, as a rule, it is necessary to open a canal before the staple is recovered. The previously opened holes are difficult to find after removing the drill. Drilling jigs are known in the state of the art, but cannot be applied in combination with staples.
DESCRIPTION OF THE INVENTION
The task of the invention is to constitute a surgical instrument in such a way that the disadvantages presented above are eliminated or, at least, reduced to a minimum. In addition, a drilling template and a recovery instrument will be built for a better implantation of integrated profiles or staples.
TASK SOLUTION
The solution of the task depends on the characteristics of the descriptive part of the claim
1.
In a surgical instrument with an implant and a handle, the implant and the handle are connected by a breaking point. Preferably the implant is a fixation profile. Fixing profiles are, for example, screws, anchors, cages, staples and / or staples.
In typical examples of execution the surgical instrument comprises an orientation channel. Preferably the orientation channel has a diameter less than or equal to 4 mm. Preferably, the guiding channel is a cannula.
As fixing profiles, different formats are taken into account. In most cases, all the U, C, half, three-quarter, or three-quarter profiles fit here, in a lateral position, as well as implants called staples or staples.
In typical execution examples the implant is a staple. Staples are suitable for fixing bone segments and / or soft tissues and / or ligaments and / or tendons.
2/23
The term “staple is applied in German and in medical technique as a technical term for fastening profiles. Both terms are applied to the present application with the same meaning.
Considerable are also fixation profiles with even more rods, for example with 4, 6 10 rods that can be constituted by a star type, honeycomb structure, network structure of random shapes, and not only planes, but also having adapted shapes to bone surfaces forming a kind of shell of a quarter, in half, of three quarters or random with rods, which are pressed and tapped on the bones, after previous drilling, through fixation and drilling templates.
The fixation profiles are very small, they are difficult to pick up and handle. Through the fact that the handle is easier to grip, compared to the fixation profile, the advantage is obtained that the implant to be recovered can be moved and / or rotated, accepted, maintained, handled comfortably through of the handle. If the implant or fixation profile is implanted at least partially, the handle can be removed from the implant or the fixation profile at the breaking point without the use of other tools.
The handle can also consist of several parts, for example two parts, the second part of the handle, which is not connected to the fixing profile, but can be connected to a breaking point facing the handle connected to the profile fixing, it is liable to break.
After breaking the second part of the handle, it constitutes a disposable drilling template, so to speak, for the rods of the fixing profile, and / or fixing holes and / or guide surfaces and / or guide threads to guide the profile of fixation when inserting it in the bone.
Preferably, the surgical instrument comprises numerous points of rupture. Thus, the advantage is obtained that the handle and the fixing profile can be easily interconnected. Another advantage is that grooves are preferably provided between the breaking points. These grooves are preferably suitable for employing a recovery instrument to be described later.
Fixation profiles, ie staples, can be made of implantable and resorbable material.
For greater efficiency, the surgical instrument consists of a single part, for example a titanium or aluminum plate. Preferred production processes are laser cutting, wire erosion, punching, flexing, or stressed procedures such as grinding and sharpening, possible staples of resorbable implantable materials or plastics. This gives you the advantage that the breaking point can be produced exactly. This is important to ensure that the breaking point is broken under the influence of defined forces and torsions. Another advantage of the mentioned production processes is that
3/23 that the surgical instrument with implant can be produced at relatively low costs.
In typical examples of execution the fixation profile or staple is made of titanium wire. This gives you the advantage that the profile can be produced at relatively low costs.
Preferably, the breaking point or most of the breaking points should be arranged in the fastening profile, so that they are in a groove in the fastening profile and a break without burr is possible, or so that the burr is in position below the surface of the fixing profile. This gives you the advantage that the fixation profile or possible burring at the breaking point does not generate tissue, skin or bone irritation.
In typical examples of execution the fixation profile has a first rod. Preferably, the fixation profile has a second rod. Preferably, the securing profile comprises a bridge suitable for connecting the first with the second rod.
Considerable are also fixation profiles with even more rods, for example with 4, 6, 10 rods that can be constituted by a star type, honeycomb structure, network structure of random shapes, and not only flat, but also having shapes adapted to bone surfaces forming a kind of shell of a quarter, in half, three quarters or random with rods, which are pressed and tapped on the bones, after previous drilling, using fixation and drilling templates.
In typical examples of execution, the first and second rods run parallel to each other. In these cases, the rods and the bridge comprise an angle between 120 ° and 15 °. Preferred examples of Besonders execution are the 90 ° fastening profiles and the so-called 26 ° fastening profiles. In 90 ° fixation profiles the bridge and one of the rods comprise a 90 ° angle. In 26 ° fastening profiles, the parallel rods form an angle of 26 ° in relation to the bridge.
In typical examples of execution the rods of the fixing profiles comprise an angle between 60 ° and 220 °. Thus the rods do not run parallel to each other. That is, the rods stand out in relation to each other or run towards each other. Thus, the advantage is obtained that the rods can take on individual tasks such as compression, fixation, bearing and / or orientation.
An increase in compression is also possible through leveled rods and provided in the example of preferential execution.
In typical examples of execution, the rod has depths, grooves, holes, grooves, grooves and / or slots. This gives you the advantage that the rods can take on individual tasks such as fixing or rolling. Another advantage is that the
4/23 fixation profile acts preferentially dampening through its specific rod shape, thus resulting in compression. The advantage is an improved fusion of the fixation profiles with the bone through the shapes of the nails mentioned above.
In typical examples of execution the free ends of the rods are pointed and / or formed by a polish. Preferably the rods have points and / or hooks. Thus, the advantage is that recovery of the integrated profiles is facilitated and the fixation profile can be anchored to the bone more easily and safely.
For greater efficiency, the surgical instrument comprises an impact area. Preferably, the impact area appears after the handle breaks in the fastening profile. Thus, the advantage is obtained that the fixation profile can be pushed into the bone or tissue with another piece, which acts on the impact area, after the handle breaks.
In typical examples of execution the fastening profile comprises a construction. Preferably, the construction forms an impact area. In this way, the advantage is obtained that the fixation profile with a handle can be pushed into the bone or tissue, even when the handle has already broken, using another tool, with which it hits the impact area.
For greater efficiency, the handle comprises an impact area. Thus, the advantage is obtained, that the surgical instrument can be propelled into the bone or tissue with the handle through the impact area, preferably through another tool.
For greater efficiency, the impact area of the handle is a construction. This gives you the advantage that the handle and the impact area can be produced in one piece.
In typical examples of execution the surgical instrument has an orifice. Preferably, the handle has the hole. Preferably, the surgical instrument has the majority of holes.
The holes preferably serve as a drilling template for the axes of the integrated element. It is also possible to apply chosen holes to fix the bones and the drilling template.
Thus, the advantage is obtained, that the handle can be positioned through the holes in the handle in drilling threads that are already in the body. In this way, the surgical instrument or the fixation profile can be positioned in front of the perforation threads or before existing holes.
In typical examples of execution the handle or the implant are formed as a channel or partially as a channel, for example as a round or multi-profile
5/23 corners. For greater efficiency, these [channels] are preferably produced from a pipe or solid material. Preferred production processes are the laser and the spraying process, all of which are possible.
In typical implementation examples, the implant, especially the staple, comprises points. Preferably, the tips are positioned between the staple rods. Through the tips the advantage is obtained, that the soft tissue, tendons or ligaments can also be fixed, for example, to the bone.
In typical examples of execution, very small versions of the staples are produced from chubby or partially chubby material, as described above. These are applied to the body preferably through an orientation channel or a cannula with a diameter less than 4mm. These have the advantage that staples can be applied via a "mini open" or percutaneous procedure through an objective access. This gives you the advantage that the process can be applied to close a meniscus injury. It is faster and simpler than a process with several anchors and a thread.
In typical execution examples, the implant, especially the staple, comprises a side flap with an orifice. This gives you the advantage that an additional guarantee is possible with a screw.
In typical execution examples, the implant, especially the staple, comprises at least one wedge and / or a flap with an orifice between the nails as a fixed spacer, the wedge having a fixed distance or a fixed angle correction.
In typical examples of execution, the staple comprises a recess and / or an orifice. This can preferably be inserted into an instrument. This gives you the advantage that the staple can be easily removed after curing or during overhaul. Preferably, the grooves or holes serve as a breaking point, so that the user can cut it objectively, for example, with a side cutter. The advantage is that only small accesses need to be made to remove these cut pieces, which is more aesthetic and heals faster.
In typical execution examples, the drilling template comprises at least one groove, for example a V or Z groove with different angles. Preferably, the drilling template is in the form of a saw template with lateral cut of the saw blade. As an alternative, the surgical instrument has a separate blade that can be broken on the handle with at least one fixing hole and / or navigation aid.
In typical examples of execution the staple or the implant comprises a majority of nails. Preferably, the staple comprises a plate, preferably a
6/23 compression plate between the rods. Preferably, the plate has a majority of holes. Preferably, the holes are used to fix with drilling threads and / or to screw the bone segments. The advantage of this procedure when fixing bone segments with plates and nails and / or screws is that during the use of a staple with nails less screws will be necessary and a constant compression can be achieved through the design of the nails, which with plates is practically impossible. In addition, it is advantageous that a staple is quicker to assemble and equally quicker to remove.
In typical execution examples, the plate design should preferably be adapted to the bone surfaces. This gives you the advantage that different requirements regarding bone formation can be met. For example, the plate should preferably be shaped, depending on the specific case, smooth or practically smooth.
In typical execution examples, the implant is in the form of a practically smooth plate and, additionally, free of angles and / or bent, in order to be able to compensate for angles and radii, or it is in the form of a level plate, mainly to compensate for differences in height.
In typical examples of execution, at least one wedge is attached to the plate. Preferably, the wedge is positioned between the rods. This gives you the advantage that the wedge has a fixed angle correction or a fixed distance.
In typical execution examples, the surgical instrument is a pipe and / or saw template that can be broken. It preferably includes a fixing hole and / or a navigation aid.
In typical execution examples, the implant is an anchor. Anchors are produced preferably from solid round material, small pipes and smooth shapes of all permitted medicinal materials. In most cases, they have wires or all types of dentition on their surfaces to securely anchor the implant to the bone. Dowel-shaped versions are also possible that extend after recovery. This gives you the advantage that the anchor can be easily retrieved. Until then, there was always the problem of the safe application of ligaments during anchor recovery, but also of the complexity and the handling of the respective recovery instruments.
In addition, it is advantageous that the surgical instrument with an anchor is only one piece and, therefore, cheap to produce. This is, above all, of immense advantage in the case of a disposable product, if all the relevant material of the operation can be packaged and prepared in a sterile way, and when it is necessary - at most - only thin cases that do not require any effort.
In typical examples of execution, the anchor is produced from a round material and
7/23 partially solid or a small barrel. Preferably, the anchor is shaped like a peg and / or has been produced in smooth shapes. For production, all materials permitted in medicine are suitable.
In typical examples of execution, the surfaces have a spinning and / or dentition. This gives you the advantage that the anchor can be securely attached to the bone.
In typical examples of execution, the surgical instrument comprises a double anchor as an implant. Thus, the advantage is that, for example, a ligament in a pre-assembled structure can be stretched with a certain tension and inserted into two bone segments with a pre-defined distance. Preferably, they are integrated here in the anchor or in the axis, as well as in all other versions, also fixing holes, diagonal fixing holes, a saw and drilling template, as well as an aid to navigation.
In typical examples of execution, the anchor has a plastic anchor rod or resorbable material. Preferably, a connection bridge is used at the anchor. This gives you the advantage that additional sewing material can be avoided.
Preferably, each anchor rod has a detachable extension shaft. This gives you the advantage that most anchors can be arranged in an arsenal, folded and rolled, side by side and / or one behind the other. This is advantageous, because the anchors of a cannula can be used in this way mainly for “seam injuries. Equally advantageous is the fact that no laborious technique from us needs to be applied. The entire operation is possible with a single instrument and a single form of implant.
In typical execution examples, the implant is a staple. Staples are applied in various sizes, in open or minimally invasive operations to tie blood vessels, intestinal tubes and other organs. The hollow shaft fixing instruments have, in most cases, a diameter of 5mm to 12mm.
In most cases, several clamps are applied, one behind the other, on both sides of the site, from which, for example, an organ must be removed.
Preferably staples are produced from partially round, partially angular and other shapes of all materials permitted in medicine. Preferably, the clamp comprises a padlock, in which both rods of the clamp are closed, when both are pushed into it. The fitting occurs preferably when a certain closure is reached. Preferably, the clips are made of plastic.
In typical execution examples, the clamps are made of titanium.
8/23
Preferably, the characteristics of the material are chosen in such a way that the clamp maintains its shape after being fitted.
The problem is that the clamps are very small parts of the construction. Its removal from the arsenal and its permanence in the mouth of the instrument until reaching the operation site is difficult, because, especially in the titanium versions, no barrier against its fall can be integrated.
In typical execution examples, the pleat comprises a lever suitable for connecting a loop. This gives you the advantage that each user can connect his favorite pleat.
In typical examples of execution, the pleat is a single piece, with a shape adapted to the handle. Thus, the advantage is obtained that the surgical instrument can be produced in a simple way as a unit and offered packaged in a sterile state.
In typical examples of execution, the clamp comprises a first and a second axis. Preferably, the shaft has a diameter of less than 5 mm, mainly less than 3.5 mm. This gives you the advantage that several axis instruments can be inserted through a small hole, mainly through the navel.
In typical execution examples, the shaft has a blind / blunt shape. This gives you the advantage that no tissue is hurt.
In typical execution examples, the shaft is partially devoid of corners and / or bent in its radius. Thus, the advantage is obtained that the clamp is positioned on a detachable extension, and the extension can be formed, depending on the specific case, in a flexible way.
In typical execution examples, the shaft is made of a flexible and malleable material. This gives you the advantage that the user can give the axis the desired inclination, before applying it, to better reach the operation site, without having to open new accesses.
In typical examples of execution, the shape of the shaft is such that most clamps, preferably up to six clamps at the same time, must be prepared in order to be closed and / or inserted one after the other.
In typical execution examples, the lever is not located on the axis, but outside the axis. Thus, the advantage is obtained that the mechanism for loading the clamps as implants can be constructed in a larger size.
Preferably, most of the clips are connected together. Preferably, the clamps are connected together on the side of the recovery direction. An alternative is the consecutive organization of the interlocking of the clamps between them, that is, one after the other. This gives you the advantage that the clamps can be placed more easily in an arsenal.
9/23
Preferably, the clamp consists of a set of materials. Preferably, at least one of these materials is resorbable. In typical examples of execution, the detachable extension comprises a lever for placing a pleat.
In typical execution examples, the implant is a cage. Such a cage is, for example, that demonstrated in DE 10 2011 002 076. Preferably, cages are used to stabilize and maintain the distance between the vertebral organs. It is important, however, that these cages are especially suitable for the following recovery procedures: mini-open and percutaneous. Here the surgical instrument preferably comprises an orientation channel. This gives you the advantage that the cage can be mounted at a certain angle, can be easily navigated and extended in parallel. The cage version can also be applied in other areas of medicine, for example in the production of vacuum spaces for cryptoplasty, as well as in veterinary medicine and in non-medical fields.
Preferably, the cage comprises an upper layer and a lower layer. Preferably, the upper and lower layers are connected together by a direction of movement. Preferably, a peg is used as a direction of movement. Thus, the advantage is obtained that the distance between the upper and lower layers can be easily modified by the movement of the pin.
In typical examples of execution, a pin, shaft, air pillow, gel pillow or ligament is used as the direction of movement. This gives you the advantage that the cage can be applied as a dynamic connection of vertebral organs.
A handle is attached as an implant by at least one breaking point to the cage.
Preferably, at least one upper and / or lower layer and / or, for example, a pin has at least one additional plate with at least one fixing hole for stiffening the vertebral organs. Preferably, both sides of the plate close through the shape of their grooves to acquire greater power. As an alternative, a seal plate can also be screwed or integrated into a detachable connection.
Preferably, at least the top and / or bottom layer and / or, for example, the pin has an adhesive rod or a plate with an adhesive rod and fixing holes to stiffen the vertebral organs, preferably on both sides of the adhesive rods fit together to acquire more power. As an alternative, a seal plate can also be screwed or integrated into a detachable connection.
In typical execution examples, other tasks are performed at the point of connection between the implant and the pleat, preferably before the pleat breaks, such as retrieval, navigation, production and fixing the cage.
10/23
In typical execution examples, the cage partially comprises editing surfaces. Preferably, these editing surfaces are suitable to compensate for the energy expenditure of the cage insertion or removal impulse.
In typical examples of execution, the instrument at its end comprises a lever suitable for connection with a recovery instrument. This gives you the advantage that production remains cheap.
Alternatively, the instrument can be connected at its end with a pleat. Preferably, the pleat and the implant are made of the same material. Preferably, laser cutting, erosion, flexibilization or spraying are used as means of production.
After the introduction of the cage, for example, in an intervertebral disc, it can rotate on impulse through the navigation links in any direction, being positioned laterally at a determined angle. The pleat may contain a scale not shown that allows the user to control and / or maintain a desired angular positioning.
In typical examples of execution, the instrument comprises a socket or a rail. In this way, the advantage is obtained that the user recognizes and / or perceives if the angular positioning has been reached and if the cage can be extended.
In typical examples of execution, the breaking point is positioned in such a way that the disengagement and / or removal of the connection, after extension of the cage, preferably occurs when a certain power or a defined pivoting moment is reached. Preferably, the pleat is removed only after this.
Preferably, the pin is formed so that, during the expansion of the cage, a certain position is not reached and the highest point of the pin is skipped. This gives you the advantage that the cage can be retrofitted and removed in a better way.
Preferably, the breaking point is formed in such a way that the removal procedure produces a defined movement. Examples of these movements are rotating or linear movements. Circumstantially, a tool can also be used, for example, in the shape of a “Meisei” or pliers to remove the breaking point.
Preferably, the instrument comprises a suitable ligament to connect the removable parts. Thus, the advantage is obtained that the removable parts can be controlled to prevent them from damaging or injuring nearby tissue and / or being lost.
In typical examples of performance, the instrument is prepared from a variety of ingredients. Thus, the advantage is obtained that all elements of the material can be produced with the best characteristics for the exercise of their functions.
11/23
In typical examples of execution, the instrument comprises a rod suitable for the exercise of the navigation movement. Preferably, the rod can be connected to the cage. Preferably, the rod is composed of a material with a texture adaptable to the shape, mainly nitinol or made of a wire suitable for navigating the cage in impulse movements. Preferably, the cage has holes or support points. This gives you the advantage that the wire or rod can be easily attached to it.
Additionally, protection of a recovery instrument is requested to insert the described surgical instrument.
Preferably, the recovery instrument comprises a pleat. This gives you the advantage that the recovery instrument can be easily used and handled by a surgeon.
For greater efficiency, the recovery instrument comprises a guide thread for the surgical instrument with implant. Preferably, the pleat is inserted into the guide thread. For greater efficiency, the fixing profile can also be inserted into the guide thread. Preferably, the guide thread is suitable to guide the pleat and then insert the fixing profiles. Most preferably, the recovery instrument comprises two or more guide threads. This gives you the advantage that the surgical instrument can be safely inserted through the recovery instrument.
In typical examples of execution, the recovery instrument comprises an impact area. Thus, the advantage is obtained that the surgical instrument can be recovered through the recovery instrument also in rigid tissues such as bones.
For greater efficiency, the recovery instrument comprises a contact surface. Preferably, the contact surface can be connected to the impact area of the fixing profiles and / or to the impact area of the pleat in working connection. Thus, the advantage is obtained that the impacts suffered by the impact area of the recovery instrument can be performed safely and, above all, at the correct angle in relation to the surgical instrument and / or in relation to the fixation profile. Thus, the advantage is obtained that the pleat is prevented from breaking from the fixation profile during the impacts suffered in the impact area of the recovery instrument.
For greater efficiency the contact surface comprises a guide thread. This gives you the advantage that the surgical instrument can be safely attached and guided to the contact surface of the recovery instrument.
Additionally, protection for the drilling template is requested during the recovery of the described surgical instrument.
Preferably, the drilling template comprises a template,
12/23 preferably with a suitable pleat to insert holes, in which the fixation profile of the surgical instrument can be placed. Thus, the advantage is obtained that the production of holes for the fixation profile is facilitated.
Another example of execution describes a drilling template for the recovery of a surgical instrument, and the appropriate template for the recovery of holes is used to fix the bone.
In typical examples of execution, the drilling template comprises a template suitable for recovering holes for bone fixation. Preferably, drill threads are introduced through the holes. This way, the advantage is obtained that the surgical instrument can be positioned relatively easily through the drilling template and through the drilling template drilling threads in the holes previously produced for the recovery of the fixation profile. Thus, the holes for the fixing profile can be easily found.
In typical examples of execution the drilling template comprises one or more guide surfaces and / or one or more guide thread (s) to guide the surgical instrument. Preferably, the guide surface is suitable for guiding the fastening profile. Preferably, the guide surface is suitable to guide the pleat during the recovery of the fixation profiles. Thus, the advantage is obtained that the fixation profile can be coupled at a defined angle in the fabric.
