A crochet needle for meniscus suture in orthopedic surgery

Abstract

The invention discloses a meniscal suture hook for orthopedic surgery, which comprises a fixing frame, a catheter, a handle and an inner cavity. A fixing ring is slidably installed on the periphery of the catheter, and threaded bolts are installed at both ends of the fixing ring. The periphery of the threaded bolt is slidably installed with a fixing frame, and the periphery of the threaded bolt on the outside of the fixing frame is rotatably installed with nuts. A kind of meniscus suture hook for orthopedic surgery includes a fixing frame, a catheter, a handle and an inner cavity. The periphery of the catheter is slidably installed with A fixed ring, threaded bolts are installed at both ends of the fixed ring, the periphery of the threaded bolts is slidably mounted with a fixing frame, and the periphery of the threaded bolts outside the fixed frame is rotatably mounted with nuts. The present invention is provided with a series of structures so that the device can limit the insertion position of the crochet needle during the operation process. The overall stability of the device is strong, manpower is saved and maintenance is convenient, and the use process is 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
