Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0027] like figure 1 As shown, the outside-to-inside meniscus suture tool of the present invention includes a handle and a suture needle, one end of the suture needle is a needle head, and the other end is a needle tail, and the suture needle is fixedly installed on the handle through the needle tail.

[0028] like figure 2 As shown, the inside of the suture needle is provided with an axial through hole, and the side wall of the needle head is provided with a thread outlet. When in use, the suture in the axial through hole of the suture needle is drawn out from the thread outlet. The suture is led out from the thread outlet on the side wall of the needle instead of passing through the sharp part of the needle, which can prevent the suture from being cut by the needle.

Abstract

The invention provides a meniscus suturing tool adopting an outside-to-inside method. The tool comprises a handle and a suturing needle, one end of the suturing needle is a needle head, the other endof the suturing needle is a needle tail, and during use, the suturing needle is fixedly installed on the handle through the needle tail; the suturing needle is internally provided with an axial through hole, the side wall of the needle head is provided with a suture outlet, and during use, the suture in the axial through hole of the suturing needle is led out from the suture outlet. According to the meniscus suturing tool, the suturing needle is provided with the side-face independent suture outlet, and the suture is not cut. The handle is arranged, the needle tail is fixed to the handle during use, shedding is not easily caused after connection, and the tool is easy to hold for operation. During clinical operation, single-needle operation suturing can be conducted, and double-needle operation suturing can also be conducted.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to an outside-in meniscus suture tool. Background technique [0002] Meniscus injury is a common and frequent sports injury. With the understanding of the structure and function of the meniscus, the treatment concept for meniscus injury has changed from "tear and remove" to "rescue the meniscus". The structural and functional integrity of the meniscus should be preserved as much as possible. More and more studies suggest that meniscus damage or loss will lead to an increase in the incidence of osteoarthritis, therefore, meniscus repair has received more and more attention. There are three methods of meniscus repair after meniscus injury, including partial meniscus resection, meniscus suture and meniscus reconstruction. Among them, meniscus suture is the mainstream repair method at present, including outside-to-inside suture, inside-out suture and all-inside Three kinds of sewing...
