Abstract

The invention provides a system of articular cartilage fixation and articular cartilage repair materials for articular cartilage injuries and articular cartilage repair, and belongs to the technical field of medical apparatuses. The system comprises an articular cartilage repair face locator, a temporary fixation kirschner wire, a depth limiting guide pin, an impactor and an articular cartilage fixing element. The locator is arranged on the articular cartilage repair face, the temporary fixation kirschner wire temporarily fixes the locator to articular cartilage and bone on a fixing hole, a fixing element guide channel of the locator punches a fixing element needle tunnel in the articular cartilage and the bone through the depth limiting guide pin, the fixing element is placed in the fixing element guide channel and beaten into the articular cartilage and bone channel by means of the impactor, and other fixing elements are implanted in the same way till articular cartilage repair is finished. The system can improve convenience and reliability of injured articular cartilage fixation, and can be used for fixing of articular cartilage defect repair materials, fixing of tendon end injury attachment faces, fixing of fracture free bone pieces and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mesh fixation system for articular cartilage. Background technique [0002] Cartilage is a "device" that acts as a cushion or shock absorber in human joints, covering and protecting joints. Cartilage acts as a load-bearing load in the human body and can reduce bone friction between joints. If the protection of cartilage is lost, there will be direct friction and collision between bones in the joints, and the human body will experience symptoms such as joint pain and swelling, and then osteoarthritis. [0003] In the course of orthopedic surgery, it is often found that the articular cartilage is stripped. In response to this situation, there is currently a lack of quick and convenient treatment methods, and in many cases the exfoliated cartilage will be removed. Because cartilage is difficult to regenerate, when the area of ​​cartilage stripping is large, if the cartil...
