Working routeway setting tool applied to intervertebral disc surgery

Abstract

The invention provides a working routeway setting tool applied to an intervertebral disc surgery. The working routeway setting tool applied to the intervertebral disc surgery comprises a guide rail base, a needle type guide rail and a hole expanding column; the guide rail base comprises a top platform, a bottom annular platform, fixing pipes and sleeves, wherein the fixing pipes are connected between the top platform and the bottom annular platform; each fixing pipe is sleeved with the corresponding sleeve; the top platform has two ends; the quantity of the fixing pipes is 2; the lower portion of each end of the top platform is connected with one fixing pipe; each sleeve can move along the length direction of the corresponding fixing pipe; the needle type guide rail is connected to the top platform, is positioned between the two fixing pipes and penetrates through a through hole; the hole expanding column comprises a pipe body and an outer pipe, wherein the pipe body is sleeved with the outer pipe; and the pipe body can movably sleeve the needle type guide rail. By adopting the working routeway provided by the invention, only a wound which is smaller than 10 mm in size is formed at the skin surface, and the wound can be sutured by one stitch only and can be covered by just a woundplast.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an applicator for a small-diameter working channel to reach a diseased part in intervertebral disc surgery, that is, a working channel applicator in intervertebral disc surgery. Background technique [0002] In spinal surgery, with the in-depth study of spinal pathology and the continuous improvement of auxiliary technologies such as intervertebral bone fusion technology, the resection of intervertebral disc soft tissue, the clearing and formation of regular intervertebral space, and the bone graft fusion device are as fully compatible as possible. The ideal space is increasingly becoming a very important part of the success of the operation. [0003] However, due to the special position of the intervertebral disc, the deepest position of the human body and the surrounding barriers that completely embed it are like a completely closed room without doors and windows. The "ceiling" ...

AI Technical Summary

Problems solved by technology

[0007] To sum up, the following problems exist in the prior art: it is difficult for existing surgical tools to provide accurate and effective working channels while minimizing damage to the central spinal cord and peripheral nerves.
