Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a surgical lead assembly. Background Art

[0002] In the medical field, nerve suturing is often used to connect and suture nerves. In the process of nerve connection and suturing, the two broken nerve bundles need to be pulled together first, and each nerve bundle in the two broken nerve bundles needs to be identified and aligned, and then each broken nerve needs to be sutured correspondingly using a suture needle. In the process of using a suture needle to suturing nerves, the two broken nerve bundles need to be kept in a pulled and aligned state.

[0003] In the prior art, in order to keep the two broken nerve bundles in a pulled and aligned state at all times, it is usually necessary to use surgical forceps or tweezers to clamp the two broken nerve bundles, and use the surgical forceps or tweezers to manually align the nerve bundles in the nerve bundles and keep them in a pulled and aligned state, so as to facilitate the doctor to sew up the broken nerves. However, in the prior art connection method of clamping the broken nerve bundles with surgical forceps or tweezers, since the nerve suturing operation often lasts for several hours, the existing method of manually clamping the nerve bundles with surgical forceps or tweezers requires the doctor to concentrate highly and maintain a fixed posture, which may easily cause the surgical forceps or tweezers to be unstable and the nerve bundles to be misaligned. In severe cases, it may even cause the nerves to break after suturing, resulting in the failure of the operation.

[0004] In view of the above situation, a nerve suture connector disclosed in Chinese patent document CN207785206U can keep the nerve bundle group aligned, reduce the misalignment of the nerve bundle group, and reduce the situation of nerve breakage. However, in the operation environment of suturing nerves, the accuracy of the puncture position of the suture wire is very high. During the suturing process, medical staff need to predict the puncture depth for each operation to avoid the puncture depth being too shallow or too deep during the suturing process, which will affect the surgical results. In complex surgical procedures, a high degree of concentration will consume a lot of energy of medical staff, resulting in reduced stability and efficiency of the operation. Therefore, it is necessary to develop a surgical lead assembly to further improve the stability and efficiency of the surgical process. Utility Model Content

[0027] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 8 A surgical lead assembly shown includes a main body 1 and a lead assembly 2, the main body 1 includes a first barrel 3 and a second barrel 4 which are detachably connected, the first barrel 3 is provided with a first barrel inner cavity 31, the second barrel 4 is provided with a second barrel inner cavity 41, the first barrel inner cavity 31 and the second barrel inner cavity 41 are combined to form a cavity 11, the first barrel 3 and / or the second barrel 4 is provided with a lead groove 5 for the lead assembly 2 to extend into the cavity 11, the lead assembly 2 includes a first lead tube 6 extending from one side of the lead groove 5 toward the cavity 11, and a second lead tube 7 extending from the other side of the lead groove 5 toward the cavity 11, the first lead tube 6 and the second lead tube 7 are detachably connected, and the first lead tube 6 and the second lead tube 7 are respectively provided with a lead opening 50 for suture wire to extend into or out of. The utility model increases the flexibility of using the lead assembly by providing a detachably connected first lead tube and a second lead tube. The suture wire enters the surgical area in the cavity through a provided channel, thereby more accurately controlling the puncture depth of the suture wire, reducing the operating errors and burdens of medical staff, and improving the stability and efficiency of the operation.

[0029] Furthermore, as a preferred embodiment of the present invention but not a limitation, when the first cylinder and the second cylinder are connected, the inner cavity of the first cylinder and the inner cavity of the second cylinder are enclosed to form a complete cavity, providing a closed and fixed space for the nerve bundle group, facilitating surgical operations.

[0030] Optionally, in some embodiments, the guide groove can be provided on the first barrel or the second barrel alone, or on both the first barrel and the second barrel. The guide assembly can provide a channel for the suture wire, and the guide groove allows the guide assembly to extend into the cavity and allows the suture wire to extend into the cavity.

[0031] Specifically, the first lead tube extends into the cavity from one side of the lead groove, and the second lead tube extends into the cavity from the other side of the lead groove. After the first lead tube and the second lead tube are connected, a channel for the suture wire to enter and exit is formed. This arrangement not only ensures the directional guidance of the wire, but also guides the suture wire in and out of the cavity without obstruction. The first lead tube and the second lead tube are connected by a detachable connection, which is convenient for medical staff to adjust the connection or disconnection of the first lead tube and the second lead tube according to surgical needs, facilitates the adjustment of the wire during the operation, and reduces the complexity of the operation.

[0032] Specifically, the lead-in ports are respectively arranged on the first lead-in tube and the second lead-in tube, and the suture wire can be extended from the first lead-in tube and extended from the second lead-in tube, or from the second lead-in tube and extended from the first lead-in tube, thereby facilitating the suturing operation for medical staff.

[0033] Optionally, in some embodiments, the first lead tube and the second lead tube may be made of a transparent plastic material.

[0034] Furthermore, as a preferred embodiment of the present invention but not a limitation, the first guide tube and the second guide tube are made of metal material. Specifically, the suture wire such as the suture needle itself has flexibility and can be deformed from a straight structure to an arc structure according to the curvature of the first guide tube and the second guide tube. The first guide tube and the second guide tube made of metal can provide sufficient support, so that the suture needle can penetrate or exit through the arc-shaped first guide tube and the second guide tube.

[0035] like Figures 2 to 7 In the surgical lead assembly shown, the first lead tube 6 and the second lead tube 7 are arranged in an arc shape, the first lead tube 6 is provided with a first lead tube connection end 61, and the second lead tube 7 is provided with a second lead tube connection end 71, and the first lead tube connection end 61 cooperates with the second lead tube connection end 71 to connect the first lead tube 6 and the second lead tube 7. Further, as a preferred embodiment of the utility model but not a limitation, the arc-shaped design of the first lead tube and the second lead tube can better fit the shape of the surgical area, help guide the suture wire to enter the surgical area at a suitable angle and connect with the nerve bundle group, thereby improving the flexibility of the operation. In addition, the arc-shaped setting of the first lead tube and the second lead tube can better adapt to the natural curve of physiological structures such as nerves or blood vessels, especially when dealing with curved or sensitive nerve tissues, which helps to reduce friction and unnecessary pressure during the operation, thereby reducing the compression and damage to the nerve bundle group and improving the safety of the operation.

[0036] Optionally, in some embodiments, in order to facilitate the movement of the first lead tube and the second lead tube, the cross-sectional area formed by the combination of the first lead tube and the second lead tube is between the semicircular area and the circular area. When the cross-sectional area formed by the combination of the first lead tube and the second lead tube is smaller than the semicircular area, the movement of the suture wire is shorter and the angle is narrow, which is inconvenient for suturing. When the cross-sectional area formed by the combination of the first lead tube and the second lead tube is the entire circular area, it is not conducive for the first lead tube and the second lead tube to leave the cavity when they move in opposite directions at the same time.

[0037] Specifically, the matching mode of the first lead tube connection end and the second lead tube connection end ensures the stability and fixity of the first lead tube and the second lead tube during use, avoids surgical errors caused by the movement or dislocation of the first lead tube and the second lead tube during surgery, and improves the accuracy of suturing and the success rate of surgery. In addition, medical staff can quickly complete the installation or adjustment of the first lead tube and the second lead tube without interrupting the surgical process, which reduces the operation time, reduces the workload of the surgical team, reduces the complexity of replacing or adjusting tools during surgery, and helps maintain the continuity and efficiency of the surgery.

[0038] Optionally, in some embodiments, the first lead tube connection end and the second lead tube connection end cooperate with each other, so that the medical staff can flexibly adjust the length and position of the first lead tube and the second lead tube according to the needs of the operation, and can quickly change the guide path of the wire as needed during the operation, thereby improving the flexibility and adaptability of the operation. When the medical staff lifts the distance between the first lead tube and the second lead tube at the same time, the first lead tube connection end remains connected to the second lead tube connection end, and the length of the channel formed between the first lead tube and the second lead tube will increase or remain unchanged. Of course, in some other embodiments, when the medical staff lifts the distance between the first lead tube and the second lead tube at the same time, the first lead tube connection end is separated from the second lead tube connection end, and the length of the channel formed between the first lead tube and the second lead tube will increase, and the suture wire can enter the cavity from the gap between the first lead tube connection end and the second lead tube connection end.

[0039] Optionally, in some embodiments, the cooperation between the first lead tube connecting end and the second lead tube connecting end can be achieved by threaded connection, snap connection, mortise and tenon connection, groove connection, magnetic connection, etc. The first lead tube and the second lead tube can be assembled or disassembled according to surgical needs, thereby improving the applicability and operational convenience of the first lead tube and the second lead tube.

[0040] like Figures 2 to 7A surgical lead assembly is shown, wherein the first lead tube 6 is provided with a first lead tube cavity 60, the second lead tube 7 is provided with a second lead tube cavity 70, the first lead tube connection end 61 is located at one end of the first lead tube 6, the second lead tube connection end 71 is located at one end of the second lead tube 7, the lead port 50 includes a first lead port 501 located at the other end of the first lead tube 6, and a second lead port 502 located at the other end of the second lead tube 7, the first lead tube connection end 61 is arranged opposite to the second lead tube connection end 71. Further, as a preferred embodiment of the utility model but not a limitation, the first lead tube cavity and the second lead tube cavity are used to accommodate and guide suture wires, and their shapes and sizes can adapt to different types of suture wires, which not only provide a safe and stable passage for the suture wires, but also may help reduce the twisting or deformation damage of the wires during the advancement or withdrawal process, ensure the smooth operation of the sutures, and improve the fluency of the operation.

[0041] Further, as a preferred embodiment of the present invention but not a limitation, the first lead tube connection end and the second lead tube connection end are arranged relative to each other, ensuring that the first lead tube and the second lead tube can be accurately docked, maintaining the overall stability of the lead assembly, specifically, when the first lead tube and the second lead tube are connected, the first lead tube connection end and the second lead tube connection end are face-to-face docked with each other, thereby ensuring that the first lead tube and the second lead tube can be closely matched to form an overall pipeline structure, so that the suture wire can pass smoothly, avoiding the interruption or repositioning of the operation due to loose connection, and improving the efficiency of the operation. It is also convenient to adjust the entry and exit path of the wire as needed during the operation, improving the flexibility of the operation.

[0042] Furthermore, as a preferred embodiment of the utility model but not a limitation, the first lead wire port and the second lead wire port are respectively located at the other end of the first lead wire tube and the second lead wire tube, ensuring that the path of the wire is controllable when entering and leaving the first lead wire tube and the second lead wire tube, which helps medical staff to more accurately control the puncture depth and position of the suture during operation, reduces operational errors, and improves the accuracy and safety of the operation.

[0043] Optionally, in some embodiments, medical personnel can place the first lead tube connection end opposite to the second lead tube connection end, and tightly connect the two by means of a snap connection. After the connection, the suture wire can be extended from the first lead port into the first lead tube cavity, pass through the nerve bundle group in the cavity, and extend from the second lead port to complete the suturing action.

[0044] like Figures 2 to 7In the surgical lead assembly shown, the outer diameter of the first lead tube cavity 60 is greater than the outer diameter of the second lead tube connection end 71, and the second lead tube connection end 71 can extend into or out of the first lead tube cavity 60. Further, as a preferred embodiment of the utility model but not a limitation, when the outer diameter of the first lead tube cavity is greater than the outer diameter of the second lead tube connection end, the second lead tube connection end can extend into the first lead tube cavity to achieve a tight connection between the two, thereby avoiding disengagement due to accidental movement during the surgical operation, and ensuring the continuity and safety of the operation. When disassembly is required, the second lead tube connection end is detached from the first lead tube cavity, which is convenient for quickly adjusting, replacing the lead path or disassembling the lead assembly according to actual conditions during the operation, thereby improving the flexibility and efficiency of the operation.

[0045] Optionally, in some embodiments, the arc-shaped second guide tube connecting end is precisely docked with the first guide tube cavity, thereby reducing direct manipulation of nerve or vascular tissue during surgery, reducing the risk of additional injury caused by improper operation, ensuring the integrity of the surgical area, and facilitating the patient's postoperative recovery.

[0046] like Figure 4 and Figure 5 In a surgical lead assembly shown, the upper end surface of the first lead tube 6 and / or the second lead tube 7 is provided with a wire outlet groove 8. Optionally, in some embodiments, the wire outlet groove is an opening or groove located on the upper end surface of the first lead tube or the second lead tube, or it can be an opening or groove located on the upper end surface of both the first lead tube and the second lead tube. The wire outlet groove helps medical staff to more accurately control the position and direction of the suture wire, and the suture wire can be more smoothly led out from the inside of the lead assembly to the outside, making it more convenient to perform suturing operations, thereby improving the efficiency and success rate of the operation.

[0047] Optionally, in some embodiments, the shape of the cable outlet groove may be a straight line or an arc shape.

[0048] Optionally, in some embodiments, during the operation, the medical staff can extend the suture wire from the first lead-in port or the second lead-in port into the corresponding first lead-in tube cavity and the second lead-in tube cavity, and then pass through the cavity to reach the outlet groove. At this time, the medical staff can easily lead the suture wire to the outside through the outlet groove to perform the knotted suture operation. Through the guidance of the outlet groove, the suture can remain stable when passing through, reducing the misoperation caused by the jitter of the wire, and increasing the stability of the surgical operation.

[0049] Optionally, in some embodiments, the lower end surface of the first lead tube 6 and / or the second lead tube 7 is provided with a threading groove. Further, as a preferred embodiment of the utility model but not limitation, medical staff can more easily insert the suture wire into the nerve bundle group during operation to ensure the correct position and depth of the wire, thereby enhancing the operability and accuracy of the operation. The threading groove helps to reduce the friction of the wire and the damage to the wire during the threading process, avoiding the risk of surgical failure caused by damage to the wire during the operation. In addition, the size of the threading groove can prevent the wire from slipping during the insertion process, ensuring the smooth progress of the operation. Through the threading groove on the lower end surface of the first lead tube and / or the second lead tube, it can be avoided that the lead assembly needs to be moved too much to adjust the wire during the surgical operation, reducing the obstruction of the surgical field, allowing medical staff to better focus on the surgical area, and improving the accuracy and safety of the operation.

[0050] Optionally, in some embodiments, the threading groove is located at an opening or groove on the lower end surface of the first lead tube or the second lead tube, or is located at an opening or groove on the lower end surface of both the first lead tube and the second lead tube. After the suture wire is passed through the interior of the lead assembly, it enters the cavity through the threading groove.

[0051] Optionally, in some embodiments, the wire threading groove corresponds to the wire outlet groove to facilitate the wire to smoothly pass into and out of the cavity.

[0052] Optionally, in some embodiments, the threading groove may be linear, arc-shaped, or in other shapes to facilitate threading operations by medical personnel.

[0053] Specifically, during the operation, the medical staff can insert one end of the suture wire into the first guide tube or the second guide tube, and then pass through the cavity through the threading groove to suture the nerve bundle group.

[0054] like Fig. 9A surgical lead assembly is shown, the first barrel 3 also includes a first upper barrel 310 and a first lower barrel 320, the first upper barrel 310 and the first lower barrel 320 enclose a first barrel inner cavity 31, the second barrel 4 also includes a second upper barrel 410 and a second lower barrel 420, the second upper barrel 410 and the second lower barrel 420 enclose a second barrel inner cavity 41. Specifically, such a configuration will be tightened after the two separated nerve bundles are sutured, and the nerve bundles will exert a certain squeezing force on the inner cavity of the first barrel. If the first barrel formed as a whole is directly pulled to the side when it is removed, it is easy to cause certain damage to the nerve bundles. The configuration of the first upper barrel and the first lower barrel allows the first upper barrel to move upward after the nerve bundles are sutured, thereby avoiding pulling of the nerve bundles when the first barrel is removed. Similarly, when the two separated nerve bundles are sutured, they will be tightened and the nerve bundles will exert a certain squeezing force on the inner cavity of the second cylinder. If the second cylinder formed as a whole is directly pulled sideways during dismantling, it is easy to cause certain damage to the nerve bundles. The arrangement of the second upper cylinder and the second lower cylinder allows the second upper cylinder to move upward after the nerve bundles are sutured, thereby avoiding pulling of the nerve bundles when the second cylinder is removed.

[0055] like Figure 4 and Figure 5 A surgical lead assembly is shown, wherein the first lead tube 6 is provided with a first positioning block 62 on the outside, and the lead groove 5 is provided with a first positioning end 51 that cooperates with the first positioning block 62, and / or, the second lead tube 7 is provided with a second positioning block 72 on the outside, and the lead groove 5 is provided with a second positioning end 52 that cooperates with the second positioning block 72. Further, as a preferred embodiment of the utility model but not a limitation, during the operation, the medical staff can insert the first lead tube and the second lead tube into the lead groove respectively, and ensure that the first positioning block and the first positioning end, and the second positioning block and the second positioning end are tightly matched. Then, through structures such as the outlet groove and the threading groove, the suture wire is introduced or led out for suturing operation.

[0056] Specifically, the first positioning block and the second positioning block cooperate with the corresponding first positioning end and the second positioning end in the lead groove to achieve accurate positioning and fixation of the lead assembly during the operation, which helps medical staff to quickly and accurately fix the lead assembly in place when installing it without complicated operations, reducing the complexity of surgical preparation, reducing operation time, and improving the work efficiency of the operating room. At the same time, the stability of the lead assembly during the entire operation is guaranteed, avoiding surgical risks caused by movement or slippage. The installation position of the lead assembly is consistent, which helps to maintain the predictability and quality control of the surgical effect when the same operation needs to be repeated multiple times, and reduces operational differences caused by human factors. In addition, the first positioning block and the second positioning block cooperate with the corresponding first positioning end and the second positioning end in the lead groove, reducing the risk of unnecessary pulling and damage to sensitive tissues such as nerves and blood vessels during surgery, protecting the integrity of the surgical area, and further improving the safety of the operation.

[0057] like Figures 1 to 8 The surgical lead assembly shown also includes an outer tube 9 connected to the outside of the main body 1, the outer tube 9 is used to fix the main body 1, the outer tube 9 is provided with an outer tube first connection groove 91 connected to the lead groove 5, the first lead tube 6 and / or the second lead tube 7 is provided with a lead tube abutment end 53, and the outer tube 9 is provided with an outer tube abutment surface 93 that cooperates with the lead tube abutment end 53. Further, as a preferred embodiment of the utility model but not a limitation, the outer tube is located on the outside of the main body, which can provide additional fixation and support for the entire surgical lead assembly, avoid displacement of the lead assembly due to careless operation, thereby affecting the accuracy of the operation, and ensure that the main body can remain stable during the operation.

[0058] Optionally, in some embodiments, the size and shape of the first connecting groove of the outer cylinder matches the wire guide groove, and the first wire guide tube and / or the second wire guide tube are connected to the wire guide groove through the first connecting groove of the outer cylinder to ensure smooth and tight connection.

[0059] Optionally, in some embodiments, the shape and size of the abutting end of the guide tube matches the abutting surface of the outer tube to ensure a close fit and stable fixation between the two. The abutting surface of the outer tube can ensure that the first guide tube and / or the second guide tube can be stably fixed and limited at a certain height after being inserted into the outer tube to avoid loosening or slipping during surgery. Specifically, the abutting end of the guide tube cooperates with the abutting surface of the outer tube to achieve a stable fixing effect, and by limiting the movement range of the guide assembly, the correct position of the guide assembly during use is ensured to avoid excessive insertion or disengagement, thereby maintaining the accuracy and consistency of the surgical process.

[0060] During the operation, the medical staff can first insert the first guide tube and the second guide tube into the first connecting groove 91 of the outer tube, respectively, and ensure that they are properly connected to the guide groove. Then, by adjusting the positions of the first guide tube and the second guide tube, their guide tube abutting ends are closely fitted with the abutting surface of the outer tube to achieve a stable fixing effect. Finally, the medical staff can introduce or lead out the suture wire through the guide assembly to perform the suture operation.

[0061] like Figures 2 to 8 A surgical lead assembly is shown, wherein the inner side of the outer cylinder first connection groove 91 is provided with an outer cylinder second connection groove 92 for the wire to pass through, the outer cylinder first connection groove 91 is arranged in the horizontal direction, and the outer cylinder second connection groove 92 is connected to the outer cylinder first connection groove 91 and arranged in the vertical direction. Further, as a preferred embodiment of the utility model but not a limitation, the outer cylinder first connection groove is arranged in the horizontal direction, and the inner side of the outer cylinder first connection groove is provided with an outer cylinder second connection groove in the vertical direction, such an arrangement enables the suture wire to change the path in both horizontal and vertical dimensions, thereby increasing the flexibility of the wire guide. In nerve suture surgery, it can adapt to the suture path requirements in different directions. The connecting structure between the outer cylinder first connection groove and the outer cylinder second connection groove not only provides a smooth passage for the wire, but also effectively avoids the entanglement or damage of the wire when changing direction, thereby reducing the problems of wire entanglement and blocking of sight during surgery.

[0062] Optionally, in some embodiments, the vertical second connecting groove of the outer cylinder is combined with the horizontal first connecting groove of the outer cylinder to provide a stable support frame for the wire. When performing deep suturing, such a setting can prevent the wire from moving or bending unnecessarily under the action of gravity, thereby ensuring the accuracy of the suturing process.

[0063] Optionally, in some embodiments, the wire outlet groove is connected to the first connecting groove of the outer tube. When the suture wire enters the first connecting groove of the outer tube from the lead assembly through the wire outlet groove, the suture wire can easily turn and enter the second connecting groove of the outer tube. This helps to control the direction of the wire, making the operation of the wire during the operation smoother and more accurate.

[0064] When it is necessary to suspend the operation, the medical staff can first insert the wire into the horizontal part of the first connecting groove of the outer cylinder, and then make it naturally transition to the vertical part of the second connecting groove of the outer cylinder. By adjusting the position of the wire in the vertical direction and limiting it with the second connecting groove of the outer cylinder, part of the wire remains in the cavity, and part of the wire is supported on the outside of the first connecting groove of the outer cylinder. The medical staff does not need to completely take out the adjusted wire when suspending the operation, and can perform suturing operations more conveniently.

[0065] like Figures 1 to 8In the surgical lead assembly shown, the first lead tube 6 and / or the second lead tube 7 are provided with a clamping portion 54, the lead tube abutting end 53 is located at the bottom of the clamping portion 54, the outer tube abutting surface 93 is close to the peripheral side of the outer tube first connecting groove 91, and the clamping portion 54 is provided with a clamping portion connecting hole 541 for external objects to cooperate and connect. Further, as a preferred embodiment of the utility model but not a limitation, the accurate position of the lead assembly in a fixed state is further guaranteed by the cooperation between the lead tube abutting end and the outer tube abutting surface, avoiding loosening or slipping during the operation, making the introduction and derivation process of the wire smoother, and reducing the complexity of the surgical operation.

[0066] In addition, the outer tube abutment surface is close to the peripheral side of the first connection groove of the outer tube, which is not only conducive to the stable installation of the lead assembly, but also enables the outer tube to provide appropriate support and limit when the lead tube clamping part is engaged, thereby preventing the lead assembly from shifting or rotating during use. When preparing and performing surgery, the lead assembly can be positioned and fixed more quickly and accurately, reducing the surgical preparation time and improving the smoothness of the surgical process.

[0067] Specifically, the connecting hole of the snap-fit ​​portion allows medical personnel to use tools such as micro-tweezers to drive the movement of the lead assembly. Furthermore, a plurality of connecting holes of the snap-fit ​​portion are provided to facilitate medical personnel to drive the movement of the lead assembly from different angles.

[0068] During the operation, the medical staff can insert the first lead tube or the second lead tube into the first connecting groove 91 of the outer tube. During the insertion process, the engaging portion 54 of the first lead tube 6 and the second lead tube 7 will contact the outer tube abutment surface 93 and gradually enter the outer tube 9. When the engaging portion 54 completely enters the outer tube 9 and is in close contact with the outer tube abutment surface 93, one end of the first lead tube 6 and the second lead tube 7 is stably fixed on the outer side of the outer tube 9.

[0069] like Figures 1 to 8 As shown, the implementation method of this embodiment is as follows:

[0072] The first lead tube 6 is provided with a first lead tube cavity 60, the second lead tube 7 is provided with a second lead tube cavity 70, the first lead tube connection end 61 is located at one end of the first lead tube 6, the second lead tube connection end 71 is located at one end of the second lead tube 7, the lead wire opening 50 includes a first lead wire opening 501 located at the other end of the first lead tube 6, and a second lead wire opening 502 located at the other end of the second lead tube 7, the first lead tube connection end 61 and the second lead tube connection end 71 are arranged opposite to each other.

[0073] The outer diameter of the first lead tube cavity 60 is greater than the outer diameter of the second lead tube connecting end 71 , and the second lead tube connecting end 71 can extend into or out of the first lead tube cavity 60 .

[0074] The upper end surfaces of the first lead tube 6 and the second lead tube 7 are provided with a wire outlet groove 8. The wire outlet groove 8 is located at an opening of the upper end surfaces of the first lead tube 6 and the second lead tube 7. The shape of the wire outlet groove 8 is an arc shape.

[0075] A first positioning block 62 is provided on the outer side of the first lead tube 6, and the lead groove 5 is provided with a first positioning end 51 cooperating with the first positioning block 62. A second positioning block 72 is provided on the outer side of the second lead tube 7, and the lead groove 5 is provided with a second positioning end 52 cooperating with the second positioning block 72.

[0076] It also includes an outer tube 9 connected to the outside of the main body 1, the outer tube 9 is used to fix the main body 1, the outer tube 9 is provided with an outer tube first connecting groove 91 connected to the lead groove 5, the first lead tube 6 and the second lead tube 7 are provided with lead tube abutting ends 53, and the outer tube 9 is provided with an outer tube abutting surface 93 that cooperates with the lead tube abutting end 53 to limit the position.

[0077] The inner side of the outer tube first connection groove 91 is provided with an outer tube second connection groove 92 for the wire to pass through, the outer tube first connection groove 91 is arranged in the horizontal direction, and the outer tube second connection groove 92 is connected with the outer tube first connection groove 91 and arranged in the vertical direction. The first lead tube 6 and the second lead tube 7 are provided with a clamping part 54, the lead tube abutting end 53 is located at the bottom of the clamping part 54, the outer tube abutting surface 93 is close to the peripheral side of the outer tube first connection groove 91, and the clamping part 54 is provided with a clamping part connection hole 541 for external objects to cooperate and connect. There are multiple clamping part connection holes 541, which are convenient for medical staff to drive the movement of the lead assembly 2 from different angles.

[0078] The medical staff can first insert the first lead tube 6 and the second lead tube 7 into the first connection groove of the outer tube 9 respectively, and ensure that they are correctly connected to the lead groove 5. Then, by adjusting the positions of the first lead tube 6 and the second lead tube 7, their lead tube abutting ends 53 are closely fitted with the outer tube abutting surface 93 to achieve a stable fixing effect.

[0079] In this embodiment, the first lead tube 6 and the second lead tube 7 do not contact the nerve bundle group. When the medical staff lifts the first lead tube 6 and the second lead tube 7 upward at the same time, the first lead tube connection end 61 and the second lead tube connection end 71 are separated, and the length of the channel formed between the first lead tube 6 and the second lead tube 7 increases. The suture wire enters from the first lead port 501, and the suture wire can enter the cavity 11 from the gap between the first lead tube connection end 61 and the second lead tube connection end 71. After the suture wire penetrates the separated left nerve bundle group and then penetrates the separated right nerve bundle group, it passes out from the second lead port 502.

[0080] Medical staff can extend the suture wire from the first lead-in port 501 or the second lead-in port 502 into the corresponding lead-in tube cavity 11, and then pass through the cavity 11 to the position of the outlet groove 8. At this time, medical staff can conveniently lead the suture wire to the outside through the outlet groove 8 to perform knotting suture operations.

[0081] The utility model increases the flexibility of using the lead assembly 2 by providing a detachably connected first lead tube 6 and a second lead tube 7. The suture wire enters the surgical area in the cavity 11 through a provided channel, thereby more accurately controlling the puncture depth of the suture wire, reducing the operating errors and burdens of medical staff, and improving the stability and efficiency of the operation.

[0082] Example 2

[0083] The difference between Example 2 and Example 1 is that a wire threading groove is provided on the lower end surface of the first lead tube 6 and / or the second lead tube 7.

[0084] During the operation, medical staff can insert one end of the suture wire into the first lead port 501 of the first lead tube 6, and then pass through the threading groove into the separated left nerve bundle group and then into the separated right nerve bundle group for suturing, and then pass it out from the second lead port 502 of the second lead tube 7.

[0085] Example 3

[0086] The difference between Example 3 and Example 1 is that the first lead tube 6 and the second lead tube 7 extend from top to bottom to one-third of the inner cavity respectively and are inserted into and contacted with the separated left nerve bundle group and the right nerve bundle group. The suture wire enters from the first lead port 501, penetrates into the separated left nerve bundle group and then penetrates into the separated right nerve bundle group, and then passes out from the second lead port 502. When the medical staff lifts up the first lead tube 6 and one end of the second lead tube 7 at the same time, the first lead tube connecting end 61 and the second lead tube connecting end 71 are separated. At this time, the suture wire still remains on the nerve bundle group. The medical staff repeats the above steps and sutures the nerve bundle group multiple times.

[0087] The first cylinder 3 also includes a first upper cylinder 310 and a first lower cylinder 320, which together form a first cylinder inner cavity 31, and the second cylinder 4 also includes a second upper cylinder 410 and a second lower cylinder 420, which together form a second cylinder inner cavity 41. When the two separated nerve bundles are sutured, they will be tightened, and the nerve bundles will exert a certain squeezing force on the inner cavity 31 of the first cylinder. If the first cylinder 3 formed as a whole is directly pulled to the side during removal, it is easy to cause certain damage to the nerve bundles. The arrangement of the first upper cylinder 310 and the first lower cylinder 320 allows the first upper cylinder 310 to move upward after the nerve bundles are sutured, thereby avoiding pulling of the nerve bundles when the first cylinder 3 is removed. Similarly, when the two separated nerve bundles are sutured, they will be tightened, and the nerve bundles will exert a certain squeezing force on the inner cavity 41 of the second cylinder. If the second cylinder 4 formed as a whole is directly pulled sideways during dismantling, it is easy to cause certain damage to the nerve bundles. The second upper cylinder 410 and the second lower cylinder 420 are arranged so that after the nerve bundles are sutured, the second upper cylinder 410 moves upward, thereby avoiding pulling of the nerve bundles when the second cylinder 4 is removed.

[0088] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
