[0028] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 10 A suturing auxiliary device shown includes a main body 1 and an auxiliary component 2 that cooperates with the main body 1. The main body 1 includes an inner tube 3 that can be placed between sutured tissues and an outer tube 4 for fixing the inner tube 3. The inner wall of the outer tube 4 is provided with an outer tube clamping end 44, and the outer wall of the inner tube 3 is provided with an inner tube limiting end 34 that cooperates with the outer tube clamping end 44. The outer tube 4 is provided with a locking member 5. The auxiliary component 2 includes a matching member 6, and the matching member 6 cooperates with the locking member 5 so that the outer tube 4 can be switched between a locked state and an open state. The utility model can ensure the stability and alignment of the nerve bundle group during the operation through the cooperation of the inner tube and the outer tube, and the role of the locking member and the matching member, thereby improving the efficiency and success rate of nerve suturing; the utility model does not need to design complex connecting plate slides and sliding fasteners, which reduces the requirements for process precision and improves the convenience of operation.

[0030] Furthermore, as a preferred embodiment of the present invention but not a limitation, the suturing auxiliary device is divided into two parts: a main body and an auxiliary part, which is conducive to rapid assembly and adjustment according to actual needs during surgery, and is also easy to clean and disinfect, thereby improving surgical efficiency. The suturing auxiliary device of the present invention is suitable for nerve bundles of different volumes and has a wide range of applicability.

[0031] Specifically, the inner cylinder is used to be inserted between the nerve bundles to be sutured to provide support and protection for the nerve bundles, and the outer cylinder is wrapped around the outside of the inner cylinder and used to fix the position of the inner cylinder to ensure that the inner cylinder does not move during the operation.

[0032] Specifically, the outer tube clamping end provided on the inner wall of the outer tube can be a raised tooth, a groove or other shape that can match with the inner tube limiting end on the inner tube. The inner tube limiting end is tightly matched with the outer tube clamping end to ensure that the inner tube is kept in a stable position relative to the outer tube, ensuring that the nerve bundle group can be stably and accurately aligned, reducing the alignment error caused by unstable human operation during surgery, and improving the safety and success rate of the surgery. In addition, the locking piece provided on the outer tube is used to further lock the position of the outer tube after the outer tube and the inner tube are fixed, to prevent the outer tube from moving or opening by mistake during surgery.

[0033] Optionally, in some embodiments, the matching piece may be a knob, a switch or other component that can interact with the locking piece. By operating the matching piece, the opening and closing of the locking piece can be controlled, thereby controlling the switching of the outer tube between the locked state and the open state.

[0034] When in use, first insert the inner tube between the nerve bundles to be sutured, then put the outer tube on the inner tube, so that the clamping end of the outer tube matches the limiting end of the inner tube, thereby fixing the position of the inner tube. Then, by operating the matching piece on the auxiliary part, control the closing of the locking piece, lock the outer tube in a locked state, and ensure the stability of the inner tube and the outer tube during the operation. When it is necessary to adjust the position of the inner tube or remove the inner tube, just operate the matching piece to open the locking piece, and the outer tube can be switched to the open state, which is convenient for medical staff to perform subsequent operations.

[0035] like Fig. 9 A suturing auxiliary device is shown, wherein the outer tube 4 comprises a first outer tube 41 and a second outer tube 42 connected to the first outer tube 41, the locking member 5 comprises a block 51 located on the first outer tube 41 and a locking portion 52 located on the second outer tube 42, and the fitting member 6 cooperates with the locking portion 52 so that the locking portion 52 abuts against or disengages from the block 51. Specifically, when the locking portion abuts against the block, the outer tube is in a locked state and can prevent the inner tube and the outer tube from moving relative to each other; when the locking portion disengages from the block, the outer tube can be opened so that the inner tube can be removed or placed.

[0036] Optionally, in some embodiments, the locking portion on the second outer tube can be a movable component or mechanical structure, such as a button, a slider, a lever, etc. The locking portion cooperates with the matching piece to achieve a locking or unlocking action, thereby locking or opening the outer tube. The interaction between the block and the locking portion ensures the tightness and stability of the outer tube when it is closed, reducing the risk of accidental sliding.

[0037] Optionally, in some embodiments, the matching piece can be a separate tool or a part of the auxiliary piece, and the matching piece is used to operate the matching locking part so that the locking part can abut or disengage from the block. Then the locking state or the open state of the outer tube is controlled. The setting of the matching piece enables medical staff to easily control the tight abutment or smooth disengagement of the locking part on the second outer tube and the block, so that the suturing auxiliary device can quickly switch the locking and opening states through simple operations during the operation, thereby improving the efficiency and safety of the operation.

[0038] like Figures 8 to 10In the suturing auxiliary device shown, the locking portion 52 is provided with a connecting groove 521, and the matching piece 6 is provided with a convex block 61 matching with the connecting groove 521, or the locking portion 52 is provided with a convex block 61, and the matching piece 6 is provided with a connecting groove 521 matching with the convex block 61. Further, as a preferred embodiment of the utility model but not a limitation, through the matching of the connecting groove and the convex block, it can be ensured that the connection between the locking portion and the matching piece is more firm and stable, and it is convenient for the matching piece to drive the locking portion to move, so that it is better suitable for nerve suturing surgery, providing a better operating experience for medical staff, thereby improving the success rate and effect of the surgery.

[0039] Optionally, in some embodiments, the locking portion is provided with a connection groove, and the matching piece is provided with a protrusion matching the connection groove. When the matching piece is inserted and rotated or pushed into place, the protrusion will be embedded in the groove of the locking portion, thereby forming a firm mechanical connection. This connection method can ensure that the matching piece drives the locking portion to move, thereby controlling the locking state or the opening state of the outer tube.

[0040] Optionally, in some other embodiments, the locking portion is provided with a projection, and the matching piece is provided with a connecting groove corresponding to the projection. By embedding the projection of the locking portion into the connecting groove of the matching piece, a fast connection can also be achieved and the locking portion can be driven to rotate or move linearly through the matching piece.

[0041] The tight fit between the protrusion and the connecting groove helps to ensure the correct alignment between the mating part and the locking part to form a fool-proof function. The device can be locked or unlocked with simple operations without complicated steps, which reduces the operation time and the fatigue of medical staff.

[0042] like Figure 6 A suturing auxiliary device is shown, wherein the first outer cylinder 41 is provided with a first outer cylinder connecting end 411, and the second outer cylinder 42 is provided with a second outer cylinder connecting end 421, and the first outer cylinder connecting end 411 and the second outer cylinder connecting end 421 cooperate to allow the rotating shaft 7 to pass through, so that the first outer cylinder 41 can rotate around the rotating shaft 7 relative to the second outer cylinder 42.

[0043] Specifically, the first outer cylinder connection end is provided with a first outer cylinder connection end opening for accommodating the rotating shaft, and the second outer cylinder connection end is provided with a second outer cylinder connection end opening for accommodating the rotating shaft. The rotating shaft passes through the first outer cylinder connection end opening and the second outer cylinder connection end opening, so that the first outer cylinder or the second outer cylinder can rotate around the rotating shaft.

[0044] Optionally, in some embodiments, when the suturing auxiliary device needs to be opened or closed, the first outer cylinder rotates relative to the second outer cylinder about the rotating shaft. Such a configuration allows the first outer cylinder to be opened and closed, thereby easily placing or removing the inner cylinder without complicated operations. At the same time, when the inner and outer cylinders are in a closed state, the rotating shaft ensures that the first outer cylinder and the second outer cylinder are closely connected and remain stably fixed, so as to accurately control the position of the nerve bundle group and perform suturing.

[0045] like Figures 8 to 10 A suturing auxiliary device is shown, the second outer tube 42 is provided with a fixing groove 422 for fixing the locking part 52, and a limiting groove 423 which is connected to the fixing groove 422 and for the card block 51 to extend into, the locking part 52 is provided with a locking limiting end 522, and the card block 51 is provided with a card block abutting end 511 which cooperates with the locking limiting end 522. Further, as a preferred embodiment of the utility model but not a limitation, the fixing groove can ensure that the locking part is stably positioned on the outer tube, avoiding positional deviation caused by external factors. Through the structure of the limiting groove, it can be ensured that the card block extends into the correct position and abuts or disengages from the locking part, thereby effectively forming a locked or unlocked state. Thereby improving the stability and reliability of the device.

[0046] Optionally, in some embodiments, the locking limit end is a protrusion or edge on the locking part. When the block enters the limit groove, the locking part is rotated by operating the mating piece, so that the locking limit end of the locking part rotates a certain angle and cooperates with the block abutment end of the block, thereby achieving a locked state.

[0047] Optionally, in some embodiments, when the first outer cylinder is rotated to a suitable position, the block extends into the limit groove, and the locking portion is slid by operating the mating piece, so that the locking limit end of the locking portion slides to a certain position and cooperates with the block abutting end of the block, thereby locking the first outer cylinder on the second outer cylinder. When the outer cylinder is locked, a stable connection between the inner cylinder and the outer cylinder can be ensured.

[0048] In addition, when the position of the inner cylinder needs to be adjusted or the inner cylinder needs to be removed, the mating piece only needs to be operated in reverse to disengage the locking limit end from the abutting end of the block, and the first outer cylinder can be switched to an open state by rotating in the opposite direction, so as to facilitate subsequent operations by medical staff.

[0049] like Figures 8 to 10A suturing auxiliary device is shown, wherein the locking portion 52 is arranged in an arc shape and is provided with a locking portion groove 523 for the block abutting end 511 to extend into, the locking limit end 522 is located at one end of the locking portion groove 523, the block 51 is provided with a block mating surface 512 for the locking limit end 522 to extend into, and the block 51 is C-shaped. Further, as a preferred embodiment of the utility model but not limited thereto, by utilizing the arc structure of the locking portion and the C-shape of the block, the locking and unlocking mechanism is realized through the interaction between the two. Such a structure is not only easy to operate, but also provides a reliable locking function between the first outer cylinder and the second outer cylinder, which helps to maintain accurate alignment and connection stability between the inner cylinder and the outer cylinder during surgery.

[0050] Optionally, in some embodiments, the locking portion adopts an arc-shaped design, which can facilitate the rotation of the locking portion. In addition, the abutting end of the C-shaped block can extend into the groove of the locking portion, and the locking limit end simultaneously extends into the matching surface of the block and is connected. The locking limit end cooperates with the abutting end of the block so that the block can fit tightly on the locking portion to prevent the block from further moving, thereby further enhancing the connection stability between the first outer tube and the second outer tube.

[0051] like Figure 6 , Figures 8 to 10 A suturing auxiliary device is shown, wherein the inner cylinder 3 includes a first inner cylinder 31 and a second inner cylinder 32 that are detachably connected, the first inner cylinder 31 is provided with a first inner cylinder connecting portion 311, and the second inner cylinder 32 is provided with a second inner cylinder connecting portion 321 that cooperates with the first inner cylinder connecting portion 311, and when the first outer cylinder 41 rotates relative to the second outer cylinder 42 around a horizontally arranged rotating shaft 7, the first inner cylinder 31 and the second inner cylinder 32 are connected in a horizontal direction.

[0052] Specifically, the detachable connection between the first inner cylinder and the second inner cylinder enables the inner cylinders to be placed and adjusted during surgery or removed after the surgery.

[0053] Optionally, in some embodiments, the detachable inner cylinder design makes the device easier to clean and maintain, and medical personnel can easily disassemble and clean the inner cylinder to remove blood and other dirt generated during the operation.

[0054] Optionally, in some embodiments, the first inner cylinder connection part and the second inner cylinder connection part are stably and detachably connected by means of a buckle, a threaded interface, a mortise and tenon structure, a magnetic structure, a groove connection structure, a fastener structure, etc. When the nerve bundle needs to be precisely aligned and fixed in the horizontal direction during surgery, the horizontal connection of the first inner cylinder and the second inner cylinder can better meet the surgical requirements and improve the accuracy and efficiency of the operation.

[0055] Specifically, when the first outer cylinder is rotated relative to the second outer cylinder about a horizontally arranged rotation axis and is in an unlocked state, the first inner cylinder and the second inner cylinder are smoothly connected or separated in a horizontal direction. By operating the opening and closing of the outer cylinder, medical staff can easily connect or separate the first inner cylinder and the second inner cylinder of the inner cylinder without the need for additional tools or complicated operation steps.

Further, as a preferred embodiment of the utility model but not a limitation, the matching design of the positioning groove and the positioning portion can effectively limit the sliding of the outer tube and / or the inner tube during the operation, ensure that the relative position between the inner and outer tubes is stable and unchanged, and can greatly reduce the surgical risks caused by the movement of the outer tube or the inner tube, and prevent the dislocation of the nerve bundle group caused by the accidental movement of the outer tube or the inner tube, thereby improving the safety and success rate of the operation. This design can also simplify the operation of medical staff, and no extra hands are needed to stabilize the outer tube, so that they can focus more on the operation itself.
