Meniscus stitching hooked needle for bone surgery

Abstract

The invention discloses a meniscus stitching hooked needle for a bone surgery. The meniscus stitching hooked needle comprises a fixed frame, a guide pipe, a handle and an internal cavity, wherein a fixing ring is slidably mounted at the periphery of the guide pipe, screw bolts are mounted at the two ends of the fixing ring, the fixed frame is slidably mounted at peripheries of the screw bolts, andnuts are rotatably mounted at peripheries of the screw bolts at outer sides of the fixed frame. The meniscus stitching hooked needle for the bone surgery comprises the fixed frame, the guide pipe, the handle and the internal cavity, wherein the fixing ring is slidably mounted at the periphery of the guide pipe, the screw bolts are mounted at the two ends of the fixing ring, the fixed frame is slidably mounted at the peripheries of the screw bolts, and the nuts are rotatably mounted at the peripheries of the screw bolts at the outer sides of the fixed frame. According to the meniscus stitchinghooked needle for the bone surgery, through arranging a series of structures, a position of penetrating of the hooked needle during the surgery can be limited when the meniscus stitching hooked needle is in use; the meniscus stitching hooked needle has the advantages that the global stability is high, labor is saved, and maintenance is convenient; and use procedures are optimized.

Description

technical field [0001] The invention relates to the technical field of orthopedic surgery, in particular to a meniscal suture hook for orthopedic surgery. Background technique [0002] On the articular surface of the tibia, there are medial and lateral half-moon-shaped bones, called menisci, whose edges are thicker and closely connected with the joint capsule, and the center is thinner and in a free state. Except for the edge parts that can repair themselves after damage, the meniscus is ruptured After meniscus resection, a fibrocartilaginous thin and narrow meniscus can be regenerated from the synovial membrane. The normal meniscus can increase the depression of the tibial condyle and line the inner and outer femoral condyles to increase the stability of the joint. It can also play the role of cushioning shock, and it is necessary to use crochet needles in the process of suturing the meniscus. [0003] The defective that existing orthopedic surgery uses the meniscus to sut...

AI Technical Summary

Problems solved by technology

[0004] 1. When performing meniscus suture operation, the user needs to keep holding the crochet needle after inserting it, so it is easy to feel tired after a long operation, such as the existing patented technology CN110731804A. In addition, the crochet needle cannot To achieve an accurate positioning, it is necessary to rotate the entire crochet suture device in a large range when there is an external fixation device;

[0005] 2. The structure of the existing crochet needle for meniscus suture is too simple, and the barb is easy to cause secondary damage to the meniscus when it is pulled out;

[0006] 3. Hand slipping is easy to occur during use, so we propose a meniscus suture crochet hook for orthopedic surgery to solve the existing problems
