[0038] A suture gun is a surgical instrument used in the suturing and repair of cartilage tissues such as the meniscus. Preoperative and / or postoperative cleaning and disinfection of the suture gun are prerequisites for ensuring the smooth progress of the suture repair surgery. This invention provides a suture gun handle that is easy to clean and disinfect, as well as a tissue suture gun using this handle. It is understood that the suture gun handle and tissue suture gun provided by this invention can be used not only for meniscus suturing but also for suturing other cartilage or soft tissues; for ease of explanation, the following embodiments are only illustrated using meniscus suturing and repair as examples.

[0039] like Figures 1-3 As shown, one embodiment of the present invention provides a suture gun handle 10, which can be used in conjunction with a gun barrel 60, a gun head 70, and a suture needle 80 to complete meniscus suturing. The suture gun includes a front handle 100, a rear handle 200, a trigger 300, and an insertion connector. The front handle 100 has a mounting hole 110 and an insertion hole 120. The mounting hole 110 is used to mount the gun barrel 60, and the insertion hole 120 communicates with the mounting hole 110, allowing the suture needle 80 to be inserted sequentially along the insertion direction. The rear handle 200 is movably disposed on the side of the front handle 100 near the insertion hole 120, and when the rear handle 200 is moved, it can push the suture needle 80 to move along the insertion direction. The trigger 300 is movably disposed on the front handle 100, and when the trigger 300 is moved, it can drive the gun head 70, which is connected to it for transmission, to move. The insertion connector is located at the end of the insertion hole 120 away from the mounting hole 110. The insertion connector allows the suture needle 80 to pass through and can be connected to the decontamination tubing. The aforementioned suture gun handle 10, front handle 100, rear handle 200, and trigger 300 can cooperate with the gun barrel 60 and gun head 70 to achieve suturing and repair of the tissue to be sutured. At the same time, the insertion connector not only allows the suture needle 80 to pass through, but also connects to the decontamination tubing, thereby introducing cleaning and disinfecting liquid into the insertion hole 120, the mounting hole 110, and the gun barrel 60 fixedly installed in the mounting hole 110. This achieves effective cleaning or disinfection of the suture gun handle 10 and the tissue suture gun 1. Cleaning and disinfection can be performed before and / or after the suture repair surgery, thereby ensuring the smooth progress of the suture repair process of cartilage tissues such as the meniscus.

[0040] It should be noted that the insertion direction in the above embodiments refers to the direction in which the suture needle 80 is inserted into the through hole 120 and the mounting hole 110 of the suture gun handle 10, and also the direction in which the suture needle 80 is pushed to move by the rear gun handle 200 when performing the suture action; and when the mounting hole 110 is coaxially arranged with the through hole 120, the insertion direction is also the extension direction of the mounting hole 110 and the through hole 120; corresponding Figure 1 The insertion direction of the suture gun handle 10 and the tissue suture gun 1 in the above examples is substantially horizontally leftward. The function of the through joint is to allow the suture needle 80 to be inserted while being able to connect the decontamination pipeline. Optionally, the through joint can be a connecting belt or a connecting pipe. As a realizable mode, as shown in Figures 2-4 The through joint includes a through connecting pipe 400, one end of the through connecting pipe 400 is detachably fixed to the end of the through hole 120 away from the mounting hole 110. The other end of the through connecting pipe 400 away from the through hole 120 has a flange 410, which is folded outward along the radial direction of the through connecting pipe 400. The through connecting pipe 400 is detachably mounted at one end of the through hole 120, allowing convenient disassembly and replacement, and the through connecting pipe 400 can be mounted to the through hole 120 only when cleaning or disinfection is needed, or the through connecting pipe 400 can be always mounted at one end of the through hole 120. And the flange 410 on the through connecting pipe 400 can form an interference fit with the decontamination pipeline, not only playing a sealing role, but also preventing falling off.

[0041] Optionally, the detachable connection between the through connecting pipe 400 and the through hole 120 can be a clamping connection, a threaded connection, or a detachable intermediate connecting piece. In an embodiment of the present application, as shown in Figures 2-4 The through connecting pipe 400 is detachably fixed to the end of the through hole 120 away from the mounting hole 110 in a threaded connection mode. The threaded connection not only has the functions of stable connection and convenient disassembly, but also has a good sealing effect itself, which can effectively prevent the overflow of decontamination liquid between the through connecting pipe 400 and the inner wall of the through hole 120. It should be noted that in the above embodiments, the structure of the front gun handle 100, the rear gun handle 200, the trigger 300 and the through joint is not specifically limited, as long as it can realize its corresponding functions. As a realizable mode, as shown in Figures 1-4As shown, the front gun handle 100 is roughly in the shape of a circular arc rod with a large curvature, and the rear gun handle 200 is roughly in the shape of a circular arc rod with a small curvature. The bottom end of the rear gun handle 200 is rotatably installed at the bottom end of the front gun handle 100. When the rear gun handle 200 rotates, the top end of the rear gun handle 200 moves closer to or further away from the top end of the front gun handle 100. The mounting hole 110 and the penetrating hole 120 are coaxially arranged at the top end of the front gun handle 100, allowing the suture needle 80 driven by the rear gun handle 200 to move along the insertion direction when the suture needle 80 penetrates into the mounting hole 110 and the penetrating hole 120. Further, the mounting hole 110, the penetrating hole 120, and the penetrating connector 400 are all circular in cross-section, and the trigger 300 is in the shape of a circular arc rod. In other embodiments, the front gun handle 100, the rear gun handle 200, the trigger 300, and the penetrating connector can have other structures.

[0042] In the suture repair process of the meniscus, as shown in Figure 5 , the gun head 70 needs to be driven to clamp the meniscus to be sutured, and then the suture needle 80 is driven by the rear gun handle 200 to penetrate into the meniscus to carry the suture thread. In an embodiment of the present application, as shown in Figures 2-6 , the suture gun handle 10 further comprises a locking structure 500. The trigger 300 has a clamping position and a release position. When the trigger 300 is moved to the clamping position, it can drive the gun head 70 connected thereto to clamp the tissue (such as the meniscus) to be sutured. When the trigger 300 is moved to the release position, it drives or allows the gun head 70 connected thereto to release the tissue to be sutured. The locking structure 500 is arranged on the front gun handle 100. The locking structure 500 can maintain the trigger 300 in the clamping position, or the locking structure 500 can allow the trigger 300 to move to the release position. The locking structure 500 maintains the trigger 300 in the clamping position, thereby enabling the gun head 70 to continuously clamp the meniscus without the need for the operator to continuously apply clamping force, thereby saving the operator's operation difficulty. When the operator uses the suture gun handle 10 provided in this embodiment, he can more focusedly drive the rear gun handle 200 to act.

[0043] As an implementable way, as shown in Figures 2-5 , the locking structure 500 comprises a locking shaft 510 and an elastic locking piece 520. The middle part of the locking shaft 510 is rotatably arranged on the front gun handle 100, and one end of the locking shaft 510 can be clamped with the trigger 300 moved to the clamping position. The elastic locking piece 520 is fixedly arranged on the front gun handle 100, and the other end of the locking shaft 510 away from the trigger 300 is pressed by the elastic locking piece 520. The elastic locking piece 520 is used to maintain the clamping relationship between the locking shaft 510 and the trigger 300 (similar to self-locking), and when the other end of the locking shaft 510 away from the trigger 300 is disturbed, the trigger 300 is allowed to move to the release position. The structure of the locking shaft 510 cooperating with the elastic locking piece 520 has the advantages of simple structure and stable locking. Further, as shown in Figures 2-4As shown, the elastic lock 520 includes an elastic lock piece, one end of the elastic lock piece is fixedly arranged on the front gun handle 100, and the other end of the elastic lock piece is pressed against the other end of the locking shaft 510 away from the trigger 300. The end of the locking shaft 510 close to the trigger 300 has a wedge-shaped hook 521, the trigger 300 is rotationally arranged on the front gun handle 100, the trigger 300 has a plurality of wedge-shaped teeth 511, the plurality of wedge-shaped teeth 511 are distributed along the rotation direction of the trigger 300, and the wedge-shaped hook 521 can be engaged with any wedge-shaped tooth 511 in the process of the trigger 300 rotating to the clamping position. In this embodiment, the trigger 300 and the locking shaft 510 form a combination similar to a pawl and a ratchet, and in the process of the operator continuously moving the trigger 300, the locking shaft 510 can lock the trigger 300 at any current position, thereby allowing the operator to adjust the rotation position of the trigger 300 according to the thickness of the meniscus. In other embodiments, the elastic lock 520 can also be in the form of a torsion spring, and the release of the trigger 300 by the locking shaft 510 is achieved by the operator pressing the other end of the locking shaft 510.

[0044] In an embodiment of the present application, as shown in Figures 2-6 The rear gun handle 200 is rotationally arranged on the front gun handle 100, and the rear gun handle 200 can be fixedly connected with the needle seat 810 of the suture needle 80 in the insertion direction. A first reset member 140 is arranged between the trigger 300 and the front gun handle 100, the first reset member 140 is pressed in the process of the trigger 300 moving to the clamping position, and the first reset member 140 is used to drive the trigger 300 to move to the release position. A second reset member 130 is arranged between the front gun handle 100 and the rear gun handle 200, the second reset member 130 is pressed when the rear gun handle 200 pushes the suture needle 80 towards the front gun handle 100, and the second reset member 130 is used to drive the rear gun handle 200 to pull out the suture needle 80 away from the front gun handle 100. The first reset member 140 and the second reset member 130 realize the automatic reset of the trigger 300 and the rear gun handle 200, and reduce the complexity of the meniscus suture repair process. As an implementable way, the first reset member 140 and the second reset member 130 can be springs, rubbers or other elastic structures. As shown in Figures 3-6 The needle seat 810 of the suture needle 80 has a fixed column 811, and the top end of the rear gun handle 200 is provided with a top-end-opened fixed groove 210, the fixed column 811 can be put into the fixed column 811 from the top end of the fixed groove 210, and in the process of the rotation of the rear gun handle 200, the suture needle 80 and the top of the rear gun handle 200 remain positionally fixed in the insertion direction (approximately horizontal direction). Further, a through hole is formed on the rear gun handle 200, which reduces the weight of the suture gun handle 10 without significantly reducing the structural strength of the rear gun handle 200. At the same time, an arc-shaped guide groove 150 is formed on the front gun handle 100, and a guide column 220 is arranged on the rear gun handle 200, the guide column 220 is inserted into the guide groove 150, and the stable rotation of the rear gun handle 200 relative to the front gun handle 100 is maintained.

[0045] like Figures 1-6 As shown, an embodiment of the present invention also provides a tissue suturing gun 1, including a gun barrel 60, a gun head 70 and a suturing gun handle 10 as described in any of the above embodiments. One end of the gun barrel 60 is fixedly disposed in the mounting hole 110, and the gun head 70 is disposed at the end of the gun barrel 60 away from the front handle 100. When the gun barrel 60 is fixedly disposed in the mounting hole 110, the gun head 70 is connected to the trigger 300 in a transmission manner. In the aforementioned tissue suture gun 1, the front handle 100, the rear handle 200, and the trigger 300 can cooperate with the gun barrel 60 and the gun head 70 to achieve suturing and repair of the tissue to be sutured. At the same time, the insertion connector not only allows the suture needle 80 to be inserted, but also connects to the cleaning and disinfection pipeline, thereby introducing the cleaning and disinfection liquid into the insertion hole 120, the mounting hole 110, and the gun barrel 60 fixedly installed in the mounting hole 110. This achieves effective cleaning or disinfection of the suture gun handle 10 and the tissue suture gun 1. Cleaning and disinfection can be performed before and / or after the suture repair surgery, thereby ensuring the smooth progress of the suture repair process of cartilage tissues such as the meniscus.

[0046] The function of the gun barrel 60 is to connect the gun head 70 and the suture gun handle 10. Understandably, the gun barrel 60 has a hollow structure, allowing the suture needle 80 to pass through the suture gun handle 10 and pierce the meniscus through the gun head 70. The function of the gun head 70 is to clamp the meniscus and guide the suture needle 80 to pierce the meniscus. As one possible method, such as... Figures 6-8 As shown, the gun head 70 is in the form of a duckbill clamp. The gun head 70 includes an upper clamping plate 710 and a lower clamping plate 720. The lower clamping plate 720 is fixedly mounted on the end of the gun shaft 60 away from the front handle 100. The upper clamping plate 710 is rotatably mounted on the lower clamping plate 720. The upper clamping plate 710 is connected to the trigger 300. When the trigger 300 moves, it can drive the upper clamping plate 710 to rotate and clamp the tissue to be sutured. The lower clamping plate 720 has a guide part 721, and the upper clamping plate 710 has a through hole 711. When the rear handle 200 pushes the suture needle 80 to move in the insertion direction, the guide part 721 guides the needle tip 830 of the suture needle 80 to pass through the through hole 711. After the needle tip 830 of the suture needle 80 passes through the through hole 711, it can pierce into the clamped meniscus. At the same time, the needle tip 830 of the suture needle 80 carries the suture thread through the meniscus, laying the foundation for the next step of suturing or knotting. The duckbill clip type gun head 70 has the advantages of mature structure and easy sewing.

[0047] After the needle head 830 of the suture needle 80 carries the suture through the meniscus, the operator reduces the driving force on the rear gun handle 200, the top end of the rear gun handle 200 moves away from the front gun handle 100, and then the suture needle 80 is driven by the rear gun handle 200 to move in the reverse direction of the insertion direction, and the needle head 830 of the suture needle 80 is retracted into the gun head 70 along the path of the penetration. When the needle head 830 of the suture needle 80 is retracted into the gun head 70, it is necessary to avoid the suture being retracted into the gun head 70 together with the needle head 830. In an embodiment of the present application, as shown in Figures 6-8 The gun head 70 also includes a pressing plate 730 and a pressing torsion spring 740. The pressing plate 730 is rotatably arranged on the upper clamp plate 710. When the pressing plate 730 rotates, it covers or avoids the through hole 711. The pressing torsion spring 740 is arranged between the pressing plate 730 and the upper clamp plate 710, and is used to drive the pressing plate 730 to rotate to a position covering the through hole 711. The outer periphery of the pressing plate 730 has a hanging tooth 731. When the pressing plate 730 rotates to the position covering the through hole 711, the hanging tooth 731 cooperates with the upper clamp plate 710 to clamp the suture extending out of the through hole 711 together with the needle head 830. In this embodiment, the pressing plate 730 covers the through hole 711 under the action of the pressing torsion spring 740. When the needle head 830 of the suture needle 80 extends out of the through hole 711, it can abut against the pressing plate 730 and drive the pressing plate 730 to rotate, thereby allowing the needle head 830 of the suture needle 80 to extend out. When the needle head 830 of the suture needle 80 is retracted into the gun head 70, the hanging tooth 731 on the pressing plate 730 clamps the suture, thereby keeping the suture through the meniscus and laying a foundation for the next step of continuing to suture or knotting.

[0048] As an implementable manner, the guide part 721 includes a warping sliding groove opened on the lower clamp plate 720. The warping sliding groove is opened on the side of the lower clamp plate 720 close to the upper clamp plate 710, and is directed to the through hole 711 by the lower clamp plate 720. The upper clamp plate 710 is drivingly connected with the trigger 300 through a connecting rod, and the connecting rod can also be arranged in the gun barrel 60. Specifically, the connecting rod is connected with the top of the trigger 300, and is used to convert the rotation of the top of the trigger 300 into the rotation of the upper clamp plate 710. The warping sliding groove can effectively guide the needle head 830 of the suture needle 80 to change the horizontal advancing direction and then extend out of the through hole 711 in the vertical direction. Further, the inner wall of the warping sliding groove is a smooth curved surface, such as an arc surface. In other embodiments, the guide part 721 can also be a guide pipe or a guide wheel. Figures 5-6 and Figure 9As shown, the suture needle 80 is movably arranged in the gun head 70, the gun barrel 60 and the front gun handle 100. As an implementable manner, the suture needle 80 comprises a needle seat 810, a needle rod 820 and a needle head 830, one end of the needle rod 820 is fixedly arranged in the needle seat 810, and the needle head 830 is fixedly arranged at the other end of the needle rod 820 away from the needle seat 810. The needle seat 810 is fixedly connected with the rear gun handle 200 in the insertion direction, and the needle rod 820 and the needle head 830 are movably arranged in the gun head 70, the gun barrel 60 or the front gun handle 100. The needle head 830 can be elastically deformed to avoid being damaged when passing through the curved sliding groove. Meanwhile, a line hooking groove 831 is arranged at the end of the needle head 830 away from the needle rod 820, and the line hooking groove 831 can carry the suture needle through the meniscus.
