Problems solved by technology

When the anchor is pressed in, the suture should neither be pulled too tight nor too loose. If the thread is too tight, because the thread directly contacts the suture, the anchor will cause cutting damage to the suture, which will affect the fixation strength and have a positive effect on the long-term efficacy of ligament repair. influences
If the thread is too loose, the anchor is not easy to compact the thread, and the thread is easy to loosen during the follow-up rehabilitation activities of the patient, which may cause fixation failure

Abstract

The invention provides a suture anchor assembly. The suture anchor assembly comprises an anchor sleeve and a clamping part, wherein the anchor sleeve is provided with an axial hole and an external thread and implanted into a human body; the clamping part is at least partially arranged in the axial hole and provided with multiple chucks, and gaps are formed among two or more chucks and used for placing sutures, wherein at least part of the wall of the axial hole is in interference fit with the clamping part when the clamping part extends into the anchor sleeve, and the gaps among the multiple chucks shrink to clamp the sutures in the gaps. In the technical scheme, the two ends of the sutures are clamped into a pressurizing device at the same time, it is avoided that since pulling is too tight, the sutures are cut and damaged by the external thread of the anchor sleeve, and knotting is not needed; in addition, by adjusting the implanting depth of the anchor sleeve, the tensile force of the sutures can be adjusted, the sutures are prevented from being too loose or too tight, operation difficulty is lowered, and the efficiency and safety of an operation are promoted.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a suture anchor assembly. Background technique [0002] The main treatment methods of traditional orthopedic sports medicine include plaster or bandage external fixation, wire suture, suture suture, tendon tissue fixation after bone opening, etc. The above methods are not firm and take a long time in the repair process. And the curative effect is not good; joint adhesion, stiffness, tissue rupture again; residual pain at the trauma site; partial loss of function and other deficiencies. In recent years, with the further development of medicine, bone anchor combined with arthroscopic minimally invasive technology has become an advanced method for the treatment of orthopedic sports medicine injuries. Its biggest advantages are minimally invasive, short operation time, rapid recovery, reduced risk of infection, and complete restoration of the original anatomy Fitting rel...
