Meniscus suture needle and meniscus suture system

Abstract

The invention discloses a meniscus suture needle and a meniscus suture system and relates to the technical field of medical instruments. The meniscus suture needle comprises a needle rod, the front section of the needle rod is warped in a curved arc shape and gradually becomes smaller along with forward extension to form a needle tip, the needle rod is of a hollow structure, a notch is formed in the front section of the needle rod, the notch expands and becomes larger inwards from the surface of the needle rod, so that a barb part capable of hooking a pull suture is formed at the notch, the notch is communicated with an inner cavity of the needle rod, a hook tip of the barb part faces the rear portion of the needle rod, the rear section of the needle rod is connected with a handheld part convenient for a hand to grab, a first fixing part for fixing one end of a suture and a second fixing part for fixing the other end of the suture, when the meniscus suture needle is used, a suture linecan penetrate into the inner cavity of the needle rod from the rear end of the needle rod and penetrates out of the notch, and then the two ends of the suture line are fixed through the first fixingpart and the second fixing part respectively. The meniscus suture needle has the advantages of being more convenient to use, higher in operation efficiency, better in suture effect and higher in clinical application and popularization 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
