Embodiment Construction

[0054] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the present invention will now be described with reference to the accompanying drawings.

[0055] Such as Figure 1 to Figure 3 , Figure 9 ,as well as Figure 11 to Figure 13 As shown, the present invention proposes a kind of intervertebral disc tissue cutting as a whole, intervertebral space forming cutter, to complete the en bloc resection of intervertebral disc tissue and take it out completely, and the space left at the same time is a suitable working space. The intervertebral disc tissue In one overall cut, the intervertebral space shaping cutter includes:

[0056] A housing 1 having a hollow cavity; the housing 1 has two ends, respectively a first end 11 of the housing and a second end 12 of the housing, and the housing has a bottom wall 121;

[0057] The first end 11 of the housing is provided with a window 15 for cutting out the intervertebral d...

Abstract

The invention provides an intervertebral disc tissue one-time overall cutting and intervertebral space forming cutter comprising a housing having a hollow cavity having a first end and a second end, a chute disposed in the hollow cavity and formed on the inner wall of the housing, a blade having a cutting edge, an adjusting hole arranged on the housing and a push-pulling bolt slideably disposed in the adjusting hole and connected with the blade. An edge of the first end forms a sealed periphery by an end part cutting edge; the second end of the housing is provided with a chisel end capable of being hammered; the chute extends from the second end of the housing to the end part cutting edge of the first end of the housing in a direction of from the second end to the first end of the housing; the chute is a continuous curve; and the blade is disposed in the hollow cavity and arranged in the chute. With seconds of cutting, ideal space for full-match either with bone grafting or a fusion cage can be produced.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cutting tool used in intervertebral disc surgery, that is, a cutting tool for cutting intervertebral disc tissue as a whole and forming intervertebral space. 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" and "floor" are bo...
