Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be further described below.
The invention provides a suture-free labrum repairing rivet, which comprises a labrum part, a rivet part 3 and a clamp holder 5;
wherein, as shown in fig. 1 and 2, the labrum comprises a fixation part 1 and a puncture part 2; the puncture part 2 is needle-shaped; the tail end of the puncture part 2 is provided with two opposite and parallel supporting legs; the fixing part 1 is a cuboid square, and the fixing part 1 is arranged between two support legs through a bearing bracket; a cable 4 is arranged between the fixing part 1 and the rivet part 3; the clamp holder 5 comprises two lap joint feet, and the two lap joint feet are respectively lapped on the outer surfaces of the two support legs, so that the clamp holder 5 is clamped on the surface of the puncture part 2.
In the embodiment, the labrum repairing rivet is used for repairing the labrum without a traditional knotting mode, and after the labrum is penetrated into the labrum, the positions of the puncture part 2 and the fixing part 1 are simply adjusted through the clamp 5, so that the labrum can be fixed very simply; the rivet part 3 is placed into the bone corresponding to the labrum by using the traditional placement mode, so that the labrum and the joint part can be positioned, and the labrum is helped to repair and heal; the traditional knotting mode is not needed in the fixing process, so that the fixing difficulty is greatly reduced, the doctor who just touches the operation can get on hand conveniently, and the success rate of the operation is improved.
In the present embodiment, as shown in fig. 3, the rivet portion 3 is a blind rivet; the inside of the hollow rivet is preset with a through hole penetrating through the upper end face and the lower end face of the rivet, and the clamp holder 5 penetrates through the through hole to clamp the two support legs, so that the positions of the clamp holder 5 and the rivet portion 3 are reasonably arranged in the operation process, and meanwhile, the clamp holder 5 is conveniently taken out after the fixation is finished.
