Meniscus Suture Needle and Meniscus Suture System

Abstract

A meniscus suture needle and a meniscus suture system relate to the technical field of medical devices. The meniscus suture needle includes a needle bar, which warps in a curved arc at the front section of the needle bar and gradually becomes smaller as it extends forward to form a needle tip; the needle bar is Hollow structure, there is a notch in the front section of the needle bar, the notch expands inwardly from the surface of the needle bar and becomes larger, so that a barb part that can hook and pull the suture is formed at the notch, the notch communicates with the inner cavity of the needle bar, and the barb The hook point of the part faces the rear of the needle bar; the rear section of the needle bar is connected with a hand-holding part that is easy to grasp by hand, a first fixing part for fixing one end of the suture, and a second fixing part for fixing the other end of the suture; When using the meniscus suture needle, the suture can be inserted into the inner cavity of the needle bar from the rear end of the needle bar and passed through the gap, and then the two ends of the suture are respectively fixed by the first fixing part and the second fixing part. end. The meniscus suturing needle has the advantages of more convenient use, higher operation efficiency and better suturing effect, and has high clinical application value.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a meniscus suture needle and a meniscus suture system. Background technique [0002] Meniscus injury is relatively common in clinical practice. Meniscus resection or shaping is usually performed for non-vascular area injury, and meniscus suture is performed as much as possible for blood supply area injury. Meniscus suture methods include outside-in suture, inside-out suture, and all-inside suture. At present, for injuries to the posterior horn of the meniscus, a special instrument is usually used to suture the meniscus completely inside, while injuries to the anterior horn of the meniscus and the body are mostly sutured from outside to inside. When suturing from outside to inside, the waist puncture needle is generally used as a threader, and the suture is introduced into the joint cavity for suture. The disadvantage is that the needle of the waist puncture needle is rel...

AI Technical Summary

Problems solved by technology

When suturing from outside to inside, the waist puncture needle is generally used as the thread passer, and the suture is introduced into the joint cavity for suture. The disadvantage is that the needle of the waist puncture needle is relatively blunt, and it is difficult to pass through the meniscus. During the operation, it is easy to cause meniscus. Secondary damage to the plate, easy to cut sutures during puncture, often causing suture breaks, sutures are not firm

[0003] The Chinese patent document "CN202426582U" discloses a meniscus suture needle specially used for suturing from outside to inside. Compared with traditional lumbar puncture, the suture needle has higher efficiency and better effect. still needs to be improved

[0005] Chinese patent document "CN109512478A" discloses a meniscus suture tool from outside to inside, which has a thread outlet on the needle side wall, and the suture is drawn out from the thread outlet, thereby preventing it from being cut by the sharp part of the needle. When suturing with a single needle, it is necessary to pull out the end of the thread through the thread catcher twice, and then use the pusher to tie the suture in the joint. This meniscus suture tool needs to be improved in terms of ease of use and surgical efficiency
