AI Technical Summary

Technical Problem

The existing meniscus suture device mainly based on suture hooks is difficult to puncture when facing thicker meniscus tissue, and due to the narrow medial gap of the knee joint, sutures are difficult to find, resulting in inefficient meniscus suture.

Method used

A meniscus suturing device is designed, including a suture hook and a clue basket. A through-grooving slot is provided with a through-grooving slot, and a cable assembly is provided with a sliding line on the through-grooving slot, and a cable assembly is used to abut with a through-grooving slot. When the first end of the thread basket forms a preset angle with the first end of the suture hook along the horizontal axis, the second end of the thread basket is meshly connected to the second end of the suture hook to form a locking structure to assist the suture hook to penetrate the meniscus tissue and lock the suture through the cable assembly.

Benefits of technology

Through the above-mentioned device, meniscus tissue can be more easily pierced and sutures can be effectively locked, improving the efficiency of meniscus suture.
