Problems solved by technology

At present, the tendon repair technology in general surgery is mainly to fix the sutured tendon on the para-articular bone with screws or other instruments. Therefore, in joint replacement, conventional tendon repair mesh, tendon repair sleeve and artificial Tendon suture products such as sutured tendon kits will not stay in place, making it difficult to perform effective tendon sutures after joint replacement

Embodiment 1

[0048] refer to Figure 1 to Figure 6 , the present invention is a kit, including a joint prosthesis 1, a stapler 2, a locking structure, a bone thread system, and a shift fork 5. The locking structure adopts thread as the main connection means. The joint prosthesis 1 has an outer convex surface, and an installation groove 11 is provided at the apex position of the outer convex surface close to the geometric shape or directly at the apex itself, and the stapler 2 is embedded in the installation groove 11 and then fixed, the stapler The upper end of the prosthesis 2 is used for binding and connecting with the artificial tendon, and the joint prosthesis 1 is connected and fixed with the external backbone through a bone thread system.

[0049] The joint prosthesis 1 can be bionically printed using 3D printing technology, so that the shape and accuracy of the product can be guaranteed, and at the same time, each threaded hole position can also be printed synchronously, and the ma...

Embodiment 2

[0055] refer to Figure 7 to Figure 9 , Embodiment 2 is basically the same as Embodiment 1, but the locking structure adopts elastic buckle as the main connection means. Specifically, the upper part of the second end of the stapler 2 is connected to the lower surface of the first end of the stapler 2 and the outer diameter of the second end is smaller than the outer diameter of the first end, thereby leaving an annular surface, A positioning column 23 extending downward is provided on the annular surface, and a positioning hole 13 matching the positioning column 23 is provided on the bottom surface of the installation groove 11. The functions of the positioning hole 13 and the positioning column 23 are the same as those in the first embodiment. Notches 12 are similar to positioning ribs 22 . And the bottom of the second end is provided with the elastic connecting cap 24 that is up big and down little down umbrella shape, and elastic connecting cap 24 is elastic material, and ...

Abstract

The invention discloses a tendon suture system for joint replacement, which comprises a joint prosthesis, a suturing device, a locking structure and a bone thread system. The joint prosthesis has an outer convex surface, and an installation groove is arranged on the outer convex surface; The appliance has a first end and a second end, the first end is provided with a suture hole, the shape of the second end matches the installation groove, so that the second end can be embedded in the installation groove; the locking structure is used to The stapler is fixed on the joint prosthesis without loosening; the bone thread system is used to fix the joint prosthesis to the external diaphysis. The invention can effectively combine the suturing device and the joint prosthesis, and fix the combined assembly on the joint backbone, while smoothly ensuring the continuity of the tendon at the wounded part, which is beneficial to the health of the tendon after operation and does not shift. The invention is used in joint replacement surgery.

Description

technical field [0001] The invention relates to the field of medical operations, in particular to a tendon suture system for joint replacement. Background technique [0002] Joint replacement is a surgical operation in which a joint prosthesis imitating an artificial joint is placed in the body to replace a diseased joint in order to relieve pain and restore joint function. Tendons are sutured and repaired during joint replacement surgery. At present, the tendon repair technology in general surgery is mainly to fix the sutured tendon on the para-articular bone with screws or other instruments. Therefore, in joint replacement, conventional tendon repair mesh, tendon repair sleeve and artificial Tendon suturing products, such as suture tendon kits, will not stay in place, making it difficult to perform effective tendon suturing procedures after joint replacement. Contents of the invention [0003] The purpose of the present invention is to provide a tendon suture system fo...
