Simple inside-to-outside meniscus stitching instrument

Abstract

The invention relates to a simple inside-to-outside meniscus stitching instrument. The simple inside-to-outside meniscus stitching instrument comprises a suture needle, a handle and a round needle; the handle is connected with the suture needle; the suture needle comprises a needle body and a needle head connected with the needle body, the needle head is of a solid structure, and the needle head is provided with a hole for penetrating through a silk suture; and the tip of the round needle is a blunt head. According to the technical scheme of the simple inside-to-outside meniscus stitching instrument, the round needle is in a half circular arc shape, the cross section is circular, and the included angle between the needle head and the needle body is 0 degree to 30 degrees. The simple inside-to-outside meniscus stitching instrument is used for solving the high cost of the stitching instrument, can be reused, and gives patients more choice rights; and secondly, the needle head of the suture needle of the inside-to-outside meniscus stitching instrument only needs a hole for penetrating and passing through the silk suture, and the simple inside-to-outside meniscus stitching instrument is basically a solid structure and hard enough no to zigzag in a joint easily.

Description

technical field [0001] The invention belongs to the technical field of meniscus suturing devices, and in particular relates to a simple inner-to-outer meniscal suturing device. Background technique [0002] The meniscus has important physiological functions for the knee joint. Meniscus suture can save the damaged meniscus to the greatest extent, relieve the symptoms of knee joint pain, and relieve the rapid wear and tear of the knee joint caused by the loss of the knee meniscus. [0003] The existing meniscus suturing techniques are divided into three types, one is total internal suturing, which is the mainstream of arthroscopic surgery now, the meniscus is sutured inside the arthroscope, and the meniscus is sutured using a disposable meniscal suturing device; to the inside; the last is to sew from the inside out. Because the latter two tools are not so convenient, and improper handling is likely to cause scars at the suture opening, the most commonly used meniscus suture t...

AI Technical Summary

Problems solved by technology

[0005] 1. Involving patent rights and import issues, the price is high, and the proportion of medical insurance reimbursement is low

[0006] 2. They are all disposable consumables, and the cost is relatively high

[0008] 4. Most of the disposable meniscal sutures have no angle, and it is relatively difficult to suture the anterior angle of the meniscus
