Description

Technical Field

[0001] The present invention relates to an implant system, which comprises at least two implants with different color codes and at least two medical instruments with different color codes, wherein the color codes of the at least two instruments correspond to the color codes of the at least two implants, wherein the coding of the at least two medical instruments comprises at least one coding element, wherein each of the at least two medical instruments comprises a first tool element and at least one second tool element, which are used to jointly manipulate one of the at least two implants, wherein the first tool element and the at least one second tool element are movable relative to each other and are arranged or formed on the distal end of the corresponding instrument, wherein each of the at least two instruments comprises an actuating device, which is arranged or formed on the proximal end of the instrument and cooperates with the at least two tool elements to move the first tool element and the at least one second tool element relative to each other under the actuation of the actuating device. Background Art

[0002] Implant systems of the type described at the outset are used in particular when the association between the implant and the instrument provided therefor (eg, application instrument) is to be simplified for the user. Color coding, also referred to as coding, achieves this purpose.

[0003] In the case of instruments made of titanium, it is known to provide color coding by anodizing. However, instruments colored in this way tend to fade or, in the worst case, change color as the number of cycles through which they are processed increases.

[0004] Alternatively, especially in the case of instruments made of medical steel, coding elements made of plastic material are used as color markings, which are fixed to the instrument with screws or by an interference fit. However, such coding elements carry the risk that they can become loose or completely detach from the instrument and thus be lost. In particular, it is absolutely unacceptable for the coding element to become detached from the instrument during surgery.

[0005] In principle, it is possible to fix the coding element to the device with an adhesive, but this often leads to biocompatibility problems. In addition, it must be taken into account that the adhesive ages and thus loses its function, thereby increasing the risk of the coding element undesirably falling off the device. Summary of the invention

[0006] It is therefore an object of the invention to improve the colour coding in an implant system of the kind initially described.

[0007] This object is achieved according to an implant system of the type described at the beginning, wherein the at least one coding element is arranged on the first tool element, and the at least one second tool element fastens the at least one coding element on the first tool element in a working position of the corresponding instrument to prevent movement in a direction toward the second tool element, wherein the first tool element and the at least one second tool element are movable relative to each other between a first extreme position and a second extreme position.

[0008] Due to the proposed further improvement of the implant system, these tool elements are used, in particular, one for holding the at least one coding element and the other for fastening the at least one coding element to the first tool element in the working position. Therefore, the loss of the at least one coding element can be avoided, especially during surgery, because the at least one coding element will not fall off the first tool element even if the connection with the first tool element is loose. This is avoided by the at least one second tool element. The second tool element actually forms a block or movement restriction in the direction away from the first tool element for the at least one coding element in the direction toward the second tool element. Specifically, the proposed further improvement makes it possible to stop using adhesive. Therefore, the loss of the at least one coding element or the undesirable separation and loss of the first tool element can be effectively avoided, especially during surgery. In addition, the easy association of the implant with the relevant instrument is possible due to the color coding. The color coding on the implant and the associated or corresponding instrument is preferably matched, so that it is clear to the user that this association, that is, which instrument the user wants to use to handle which implant.

[0009] Advantageously, each instrument comprises at least two coding elements and at least one of the at least two coding elements is arranged on the first tool element and / or on the at least one second tool element. In this way, the recognition of the different instruments can be improved. For example, a coding element can be arranged on each tool element so that the coding of the instrument is always easily visible, i.e. no matter how the instrument is placed down or held.

[0010] Advantageously, the first tool element and the at least one second tool element are arranged or formed so as to be displaceable relative to one another or to be pivotable about a pivot. Thus, in particular, a pliers-like or scissors-like instrument can be formed. For example, the tool elements that are pivotable relative to one another can also be arranged at the distal end of a tubular or sliding shaft. For example, the fastening of the coding element can also be achieved by means of a second tool element that is displaceable relative to the coding element. This can be achieved, for example, by means of a displacement of the second tool element relative to the first tool element parallel to the longitudinal axis of the instrument.

[0011] If the first tool element and the at least one second tool element are coupled or connected to each other via a pivot member defining a pivot axis, the instrument can be configured in a simple manner. Thus, the mouth part defining the mouth of the instrument can thus be formed by two or more according elements, i.e. both in the case of scissor-like instruments with rigid branches and in the case of tubular shaft instruments or sliding shaft instruments.

[0012] In particular, by configuring the pivot member in the form of a connecting screw or in the form of a rivet, a coupling of the tool elements to one another can be achieved in a simple manner.

[0013] According to another preferred embodiment of the present invention, the first tool element and the at least one second tool element are mounted against each other so as to be movable in the support area, and the at least one coding element is arranged on the first tool element on the distal side of the support area. For example, the support area can be a connection area of ​​an instrument, wherein the tool elements are connected to each other, for example, by means of a pivot member. Due to the arrangement of the at least one coding element on the distal side of the support area, the coding of the instrument can be easily seen. In addition, the coding of the instrument is close to the implant manipulated by the instrument. This makes it easy for the user to visually check whether a suitable instrument has been selected for the corresponding implant. This is the case if the color codings match or correspond to each other, for example have the same color. If the color codings are different, for example because the color of the coding element is a different color from the color of the implant, this is an incorrect association.

[0014] Advantageously, the first tool element has a coding element container and the at least one coding element is at least partially, especially completely, retained in the coding element container by force locking and / or forced locking and / or by material bonding. The at least one coding element can be completely contained in the coding element groove or partially protrude therefrom. Specifically, the coding element container can, in particular in the working position, keep the at least one coding element fastened to the first tool element. In particular, the coding element container can be configured to prevent the at least one coding element from moving in a direction away from the at least one second tool element. This can be achieved by force locking or forced locking between the at least one coding element and the first tool element. Optionally, additionally or alternatively, the at least one coding element can also be connected to the instrument by material bonding. Therefore, in particular, additional fastening of the coding element on the instrument can be achieved.

[0015] Advantageously, the at least one coding element is held in the coding element container only in a force-locked and / or positively locked manner, in particular without adhesive, or only by material bonding. Thus, for example, it can be fixed completely without adhesive or the like, thereby extending the service life of the device; or the coding element can also be fixed only by material bonding, for example by gluing, soldering or welding, thus minimizing the production costs.

[0016] If the at least one coding element is screwed into the coding element receptacle, the at least one coding element can be connected to the first tool element in a simple manner. Alternatively, it can also be pressed in in a positively locking manner.

[0017] The coding element container preferably comprises a perforation. The perforation makes it possible in particular to easily identify the at least one coding element accommodated and held in the coding element container. Thus, the user can directly recognize which color the coding element held in the coding element container has when he looks at the outer surface of the first tool element facing away from the second tool element.

[0018] If the through-opening has an internal thread, the at least one coding element can be fixed in a simple manner in the coding element receptacle. The coding element can thus be screwed into the coding element receptacle.

[0019] Advantageously, the at least one coding element has an external thread corresponding to the internal thread. This structure facilitates the connection of the at least one coding element to the first tool element.

[0020] In order to further reduce the risk of the at least one coding element falling off the first tool element, it is advantageous if the perforation tapers at least in a section in a direction pointing away from the at least one second tool element. It can also taper over its entire length. The perforation thus forms a barrier and thus a fastening device for the at least one coding element on the first tool element. A movement of the first tool element away from the second tool element through the perforation can thus be reliably avoided.

[0021] In particular, the production of the instrument can be simplified by defining a coding element receptacle having a longitudinal axis which is parallel or substantially parallel to the pivot axis. The coding of the instrument can thus be easily recognized when the bearing area of ​​the instrument is visible.

[0022] Advantageously, the first tool element has a thickness in a direction parallel to the coding element receptacle and the length of the coding element corresponds at most approximately to the thickness of the tool element. In particular, the coding element can thus be configured to be flush on both sides, i.e. on one side on the outer side of the first tool element facing away from the second tool element and on the other side on the side of the first tool element facing the second tool element.

[0023] Advantageously, the coding element container has an observation opening pointing away from the at least one second tool element and an insertion opening pointing in the direction of the at least one second tool element, and the cross-sectional area of ​​the observation opening is smaller than the cross-sectional area of ​​the insertion opening. This configuration makes it possible in particular to fasten the at least one coding element in the coding element container in a simple manner without it falling out through the observation opening. By selecting the cross-sectional areas of the observation opening and the insertion opening, the at least one coding element can, for example, be introduced into the coding element container only through the insertion opening. It is then virtually impossible for it to pass through the coding element container through the observation opening.

[0024] Advantageously, the insertion opening is at least partially, in particular completely, covered or closed by the at least one second tool element in the working position. Like this, the at least one second tool element can fasten the at least one coding element in the coding element container and will not fall out when the instrument adopts the working position.

[0025] In order to be able to clean the instrument in a simple and reliable manner, it is advantageous if the instrument can be brought from a working position into a processing position in which the first tool element and the at least one second tool element can be moved relative to one another beyond one of two extreme positions and in which the at least one second tool element releases the at least one coding element in the processing position, in particular without blocking the insertion opening. For example, in the processing position, the tool elements can be pivoted relative to one another by 90° or more. In each case, in the processing position, they are moved relative to one another until the at least one second tool element no longer covers the at least one coding element, not even partially. This can be achieved in particular by the at least one second tool element unlocking the insertion opening in the working position.

[0026] The at least one coding element is preferably fastened in the coding element container, in particular in the processing position, by material bonding with the first tool element and / or by plastic deformation together with the first tool element. This further improvement can in particular avoid with great reliability that the at least one coding element is inadvertently detached from the first tool element in the processing position. The material bonding can in particular be achieved by welding or brazing. The plastic deformation can in particular lead to a local forced connection, which prevents the at least one coding element from moving relative to the coding element container.

[0027] If the at least one coding element is fastened in the coding element container by crushing or destroying at least one of the external and / or internal threads, the at least one coding element can be fastened in the coding element container in a simple manner. For example, the threads can be destroyed by laser welding. The crushing of the at least one thread can be achieved mechanically, for example, using a suitable tool. In particular, it can be prevented that the at least one coding element can be unscrewed from the coding element container.

[0028] According to another preferred embodiment of the present invention, it can be provided that the end of the at least one coding element pointing away from the at least one second tool element is arranged or formed to be flush or substantially flush with the side of the first tool element pointing away from the at least one second tool element. Thus, in particular, the end face of the coding element extending perpendicularly to the longitudinal axis of the coding element can be integrated virtually seamlessly into the side of the first tool element. In other words, a flush fit of the coding element can thus be achieved.

[0029] In particular, the assembly of the implant system can be simplified by the at least one coding element having a tool engagement element, which is open in the direction of the at least one second tool element. In particular, the tool engagement element can be configured in the form of a slit, an inner polygonal socket or an inner multi-lobed socket. This design particularly simplifies the introduction of the at least one coding element into the coding element container, for example by screwing it in.

[0030] Advantageously, at least one coding element is arranged on the at least one second tool element in a similar manner to the first tool element. As indicated above, in particular two or all tool elements can be equipped with coding elements. If the coding element is arranged on the at least one second tool element, the first tool element prevents the passage of the coding element in the direction toward the first tool element. The advantage of arranging two or more coding elements on the instrument is in particular that the user can easily recognize the coding of the instrument, regardless of its position or orientation.

[0031] Advantageously, at least one of the at least two instruments comprises at least two coding elements and at least one of the at least two coding elements is arranged or formed on the actuating device. Thus, the instrument can still be easily identified even when the coding element arranged or formed on one of the tool elements is no longer identifiable, for example due to contamination or when the coding element is covered by body tissue during surgery. In particular, two, three or more coding elements can be arranged on the actuating device, thereby further improving the association of the instrument with the implant.

[0032] The fact that the actuator comprises two actuating elements that are movable, in particular pivotable, relative to each other can in particular further simplify the manipulation of the implant system. This structure of the actuator in particular enables the manipulation of instruments in the form of scissors. For example, the actuator can comprise two branches that are pivotable relative to each other, which are rigidly connected to the tool element or are connected to the tool element via a force transmission member. Thus, a scissor-like instrument or a tubular shaft or sliding shaft instrument can be formed.

[0033] A simple structure of the at least two instruments can be achieved in particular by configuring the two actuating elements in the form of rigid branches and the distal end of each actuating element bearing or comprising a tool element.

[0034] The two actuating elements are preferably pivotable about a pivot axis. In particular, a simple-structured instrument can thus be obtained.

[0035] Advantageously, one of the at least two coding elements is arranged on at least one of the two actuating elements. In particular, at least one coding element can be arranged or formed on each of the two actuating elements. Two or more coding elements can be arranged or formed on each actuating element. When the coding element arranged or formed on one of the tool elements is no longer identifiable, for example due to contamination or when the coding element is covered by body tissue during surgery, the association of the instrument with the implant can still be reliably determined.

[0036] Furthermore, it is advantageous if the instrument comprises a biasing device for applying a biasing force which holds the actuating device in an extreme position. For example, the biasing device holds the two actuating elements in an extreme position in which they are separated from each other to the greatest extent, in which the tool elements are at a maximum distance from each other. In particular, the extreme position defined by the biasing device can be a position in which at least one instrument is in a working position. Thus, the biasing device can in particular ensure that the at least one coding element is fastened to the first tool element, i.e. in particular when the at least one instrument is not actuated.

[0037] Advantageously, the biasing device comprises at least one biasing element and the two actuating devices can be moved towards each other against the force of the at least one biasing element. For example, each actuating element can comprise a biasing element, for example also formed in one piece with the actuating element, the biasing element being in particular in the form of a leaf spring. The free ends of the biasing elements form the automatic ends of the respective actuating element, the free ends being for example connected to each other, in particular connected to each other in a movable manner.

[0038] Advantageously, the biasing device can be inactive for transferring at least one medical device from the working position to the treatment position. For example, the biasing device can define an extreme position on the working position, in which the actuating element and in particular also the tool element are at a maximum distance from each other. For example, the biasing elements engaged with each other in the working position can be disengaged to facilitate the transfer of the actuating element and the tool element connected or coupled thereto from the working position to the treatment position.

[0039] According to a preferred embodiment of the invention, it can be provided that the at least two instruments are configured in the form of clip appliers. In particular, they can have tool elements formed in different ways so as to be able to manipulate implants of different sizes in the form of clips.

[0040] Advantageously, the at least two implants are configured in the form of surgical clips. In particular, they can be configured in the form of aneurysm clips. Such implants can be used in particular for clamping blood vessels.

[0041] If the at least one coding element is made of plastic or metal, the implant system can be color-coded in a simple and cost-effective manner.

[0042] According to another preferred embodiment of the present invention, it can be provided that at least two implants are made of implant material, at least two corresponding coding elements are made of coding element material, and the implant material and coding element material are the same. This configuration can especially realize the color coding of both implant and coding element, and thus realize the same or at least nearly the same color coding of the instrument. Therefore, a particularly good visual association between the instrument and the implant can be realized.

[0043] The surfaces of at least two implants and at least two coding elements are preferably at least partially, in particular completely, colored or provided with a colored coating. This configuration enables, in particular, a very good visual association between the implant and the associated instrument.

[0044] Advantageously, the at least one coding element is colored by a color-treated surface or has a color-treated surface, and the at least two implants are color-coded in the same manner. If the at least one coding element and the at least two implants are color-coded in the same manner, a particularly good matching of the color impressions can be achieved, which facilitates the user's association of implant and instrument.

[0054] Figure 1 An embodiment of an implant system is schematically shown in FIG. 1 , which is generally indicated by reference numeral 10. The implant system 10 includes Figure 1 A first medical device 12 and a medical device 14 are schematically shown in FIG.

[0055] Additional instruments may also be included in alternative embodiments of implant system 10 .

[0056] The implant system 10 also includes Figure 1 Schematically shown are a first implant 16 and a second implant 18. The first instrument 12 and the second instrument 14 differ in at least one characteristic, such as size or actuation force.

[0057] In order to distinguish between the instruments 12 and 14, they are color coded as explained in detail below.

[0058] By way of example, instrument 12 is shown in the form of a clip applier 20.

[0059] As an example, the first implant 16 is depicted in the figure in the form of a surgical clip 22 , namely an aneurysm clip 24 .

[0060] In order to be able to distinguish the implants 16 and 18 from each other, they are color-coded. The first implant 16 is colored with a first color and the second implant 18 is colored with a different color. This color coding of the implants 16 and 18 and the optional additional implants included in the implant system 10 can make it easy for the user to distinguish them.

[0061] The implants 16 and 18 may differ in shape and size, as well as, for example, the closing or clamping force of the two clamp arms 26 and 28 , wherein the clamping force is exerted by the spring element 30 of the clamp 22 .

[0062] In order to be able to reliably select the appropriate instrument 12, 14 for manipulating the respective implant 16, 18, the instruments 12 and 14 are also color-coded. This object is achieved by means of coding elements 32 and 34 arranged on the respective instruments 12 and 14.

[0063] The instrument 12 shown in the figures comprises two elongated branches 36 and 38 which are mounted movably relative to each other in a bearing area 40. The distal ends of the branches 36 and 38 form first and second tool elements 42 and 44 between which the implant 16 or 18 can be received and held.

[0064] The branches 36 and 38 form actuating elements 46 and 48 of an actuating device of the instrument 12 , which is denoted as a whole by the reference numeral 50 .

[0065] The actuating elements 46 and 48 are movable relative to one another, ie are pivotable about a pivot axis 52 . The tool elements 42 and 44 are therefore coupled to one another so as to be pivotable about the pivot axis 52 .

[0066] The pivot axis 52 is defined by a pivot member 54. In the embodiment of the instrument 12 shown in the figures, the pivot member 54 is configured in the form of a connecting screw 56. In an alternative embodiment, the pivot member 54 may be configured in the form of a rivet.

[0067] The instrument 12 further comprises a biasing device 58 for applying a biasing force for maintaining the actuating device 50 in the extreme position.

[0068] The biasing device 50 includes two biasing elements 60 and 62 which are arranged and configured such that the two actuating elements 46 and 48 can be moved toward each other against the action of the biasing elements 58 and 60 .

[0069] The biasing elements 60 and 62 form the proximal end portions of the actuating elements 46 and 48. The free ends 64 and 66 of the biasing elements 66 and 62 thus also form the free ends 64 and 66 of the actuating elements 46 and 48, which engage with each other and are as Figure 1The schematic diagram of the apparatus 12 is shown in Figure 1 to hold the apparatus 12 in an open position defining a first extreme position.

[0070] When the actuating elements 46 and 48 are moved toward each other, the branches 36 and 38 are pivoted and the tool elements 42 and 44 formed thereon are moved toward each other, so that the instrument mouth 68 defined by the two tool elements 42 and 44 is closed.

[0071] In the working position of the instrument 12, the free ends 64 and 66 of the biasing elements 60 and 62 are engaged. The maximum proximal position of the tool elements 42 and 44 defines another position in the working position, namely the second extreme position, that is, when the instrument mouth 68 is closed, such as Figure 7 The closed position thus defined defines a second extreme position of the mouth of the instrument.

[0072] As described and in Figure 1 As schematically shown in FIG. 4 , the tool elements 42 and 44 are movable relative to each other between these two defined extreme positions when the free ends of the biasing elements 60 and 62 engage each other.

[0073] When free ends 64 and 66 are disengaged, branches 36 and 38 can be pivoted even further away from each other, for example into Figure 5 4. The position shown in FIG. 4 is one in which the tool elements 42 and 44 are aligned approximately at right angles to each other.

[0074] When the free ends 64 and 66 are disengaged, the branches 36 and 38 can be pivoted almost freely relative to each other. Figure 1 When the first extreme position shown in Fig. 1 is further away from each other, the instrument 12 is located in the processing position. During cleaning and disinfection, i.e. during processing, the instrument 12 is preferably stored in this position.

[0075] As described above, the biasing device 58 is therefore ineffective in transferring the instrument 12 from the working position to the treatment position.

[0076] The coding element 32 is accommodated on the instrument 12 in a coding element receptacle 70 . The coding element receptacle 70 is formed on the first tool element 42 distally of the pivot axis 52 and thus on the distal side of the bearing region 40 .

[0077] The coding element receptacle 70 is configured in the form of a perforation 72 .

[0078] In one embodiment, the through-hole 72 includes internal threads 74 .

[0079] The coding element receptacle 70 defines a coding element receptacle longitudinal axis 76 that extends parallel to the pivot axis 52 .

[0080] The coding element 32 has an outer thread 78 which corresponds to the inner thread 74 . This makes it possible to screw the coding element 32 into the coding element receptacle 70 .

[0081] The coding element container 70 has an observation port 80 pointing away from the second tool element 44 and an insertion port 82 pointing in the direction of the second tool element 44. The cross-sectional area of ​​the observation port 80 is smaller than the cross-sectional area of ​​the insertion port 82. This is achieved in the embodiment shown in the figure by a tapered portion 84 formed between the insertion port 82 and the observation port 80. The tapered portion is adjacent to a hollow cylindrical hole portion 86 provided with an internal thread 74.

[0082] The coding element 32 furthermore has a tool engagement element 88 in the form of a slot 90 which is open in the direction towards the second tool element 44 .

[0083] In an alternative embodiment, the tool engagement element 88 is configured in the form of an inner polygonal socket or an inner multi-lobed socket.

[0084] As described above, because the through hole 72 tapers in the section in the direction away from the second tool element 44, the coding element container 70 can accommodate the coding element 32 in a positively locked manner so that the coding element 32 cannot pass through the observation port 80. Because of this structure of the coding element container 70, the coding element 32 is fastened to the first tool element 42 and does not fall out of the observation port.

[0085] The coding element 32 is further secured so as not to fall out of the coding element container 70 through the insertion opening 82 .

[0086] The first fastening element forms the second tool element 44 , which holds the insertion opening 82 at least partially covered or closed in the working position and completely covered or closed in the other position.

[0087] exist Figure 7 It can be easily seen in the sectional view in FIG. 8 that the second tool element 44 in the closed position completely covers and thus closes the insertion opening 82. This can also be seen in FIG. Figure 4 It is easy to see in Figure 4 The tool elements 42 and 44 shown in the figure are in a position relative to each other in the working position (i.e., in a position in which the biasing elements 60 and 62 engage with each other with their free ends 64 and 66), i.e., in the second extreme position, the second tool element 42 completely covers the insertion opening 82, so that the coding element 32 is not visible.

[0088] However, in the processing position, the second tool element 44 does not block the insertion opening 82 at all, as shown in FIG. Figure 5Schematically shown in FIG. In the treatment position, the tool elements 42 and 44 are moved relative to each other beyond one of two defined extreme positions. In the embodiment shown in the figures, as already explained, the first extreme position is defined by the maximum opening of the instrument mouth 68, in which the free ends 64 and 66 of the biasing elements 60 and 62 are engaged. Beyond this extreme position, the tool elements 42 and 44 can be pivoted further away from each other when the free ends 64 and 66 are disengaged.

[0089] In the above-described manner, the coding element 32 is held in the coding element receptacle 70 in a force-locking and / or positive-locking manner, ie only in a force-locking and / or positive-locking manner, ie without adhesive.

[0090] The first tool element 42 has a thickness 92 in a direction parallel to the coding element receptacle longitudinal axis 76 . A length 94 of the coding element 32 parallel to the coding element receptacle longitudinal axis 76 corresponds approximately to the thickness 92 of the tool element 42 .

[0091] In one embodiment, the coding element 32 is additionally fastened in the coding element container 70 so that in the processing position (in which the second tool element 44 does not block the insertion opening 82) the coding element 32 cannot fall out of the coding element container 70. In one embodiment, this is achieved by material bonding of the coding element 32 to the first tool element 42 and / or by plastic deformation of the coding element 32 together with the tool element 42.

[0092] In one embodiment, this additional tightening is achieved by crushing or breaking the threads of the outer thread 78 and / or the inner thread. For example, this can be achieved by laser welding.

[0093] A permanent plastic deformation of the coding element and / or the tool element 42 in the region in which they engage one another can permanently prevent a relative movement of the coding element 32 relative to the coding element receptacle 70 and thus relative to the first tool element 42 .

[0094] Figure 8 Another embodiment of the first medical device 12 of the implant system 10 is schematically shown in FIG.

[0095] Figure 8 The embodiment of the device 12 shown in FIG. 1 is similar in structure to that of the device 12 using Figures 1 to 7 The embodiments of the first medical device 12 described above are substantially similar. Therefore, for the sake of clarity, the same reference numerals are used to denote the same elements and components. However, Figure 8 The implementation method and Figures 1 to 7The embodiment in FIG. 1 differs in that a respective thickening 180 is formed on each of the two actuating elements 46 and 48, said thickening being in the form of a rounded projection pointing in the direction of the respective other actuating element 46 or 48. Formed in each of the two thickenings 180 is a hollow cylindrical coding element receptacle 170 which defines a longitudinal axis 172 extending parallel to the pivot axis 52.

[0096] Each of the two thickened portions 180 is arranged or formed on the actuating elements 46 and 48 in the transition region to the biasing elements 60 and 62 , respectively.

[0097] The corresponding coding elements 132 are inserted into the two coding element receptacles 170. The two coding elements 132 correspond to the coding element 32, so that they are, for example, identically color-coded.

[0098] The two additional coding elements 132 arranged or formed on the actuation device 50 enable the surgeon to reliably manipulate the first implant 16 with the instrument 12 even when the coding elements 132 are, for example, contaminated or not visible for other reasons.

[0099] In an alternative embodiment of the medical device 12, as Figure 8 As shown in FIG. 1 , instead of two thickenings 180 , the thickening 180 with the coding element 132 is arranged or formed on only one of the two actuating elements 46 or 48 .

[0100] In the embodiment shown in the figures, an end 96 of the coding element 32 pointing away from the second tool element 44 is arranged or formed flush or substantially flush with a side surface 98 of the first tool element 42 facing away from the second tool element 44 .

[0101] In one embodiment, the coding element 32 and / or 132 is made of a plastic material.

[0102] In one embodiment, the coding element 32 and / or 132 is made of metal.

[0103] Implants 16 and 18 are made of implant material. Coding elements 32, 132 and 34 are made of coding element material. In one embodiment, the implant material and the coding element material are the same. Specifically, this makes it possible to design coding elements 32 and 132 or 34 and implants 16 and 18 to be colored in the same way.

[0104] In one embodiment, the surfaces of the implants 16 and 18 and the surfaces of the coding elements 32, 132 and 34 are at least partially colored or provided with a colored coating. In one embodiment, the surfaces of the implants 16 and 18 and the surfaces of the coding elements 32, 132 and 34 are completely colored or provided with a colored coating.

[0105] In one embodiment, the coding elements 32, 132 and 34 are colored or have a color-treated surface. The implants 16 and 18 are color-coded in the same manner. Therefore, a close match of the color coding of the implants 16, 18 and the instruments 12, 14 can be achieved.

[0106] In addition to the coding element 32 on the first tool element 42, the coding of the instruments 12 and 14 can be further improved if another coding element is arranged in a similar manner on the second tool element 44. The coding element arranged on the second tool element 44 is then secured by the first tool element 42 to prevent it from falling out in the working position.

[0107] The advantage of arranging the second encoding element on the second tool element 44 is that even Figure 4 The coding of the instrument 12 is also visible in the perspective shown schematically in FIG. Thus, a reliable association of the instruments 12 and 14 with the corresponding implants 16 and 18 can be achieved.

[0108] The implant system 10 may in principle comprise any number of implants. In particular, there may be more than two different implants.

[0109] Each implant type in implant system 10 is preferably color coded with a different color. Implant system 10 may specifically include any number of instruments, ie it is not limited to instruments 12 and 14. Implant system 10 preferably includes a number of different instruments corresponding to the number of different implants.

[0110] The coding of the described instruments 12 and 14 is not limited to the schematically shown clip applier 20. The coding can also be formed in the case of any other instrument, wherein a tool element of the instrument, for example the second tool element, in the working position secures the coding element to the first tool element to prevent it from being lost.
