vertebral body fusion

Abstract

The invention relates to a centrum fusion device. The centrum fusion device includes a first lifting rod, a second lifting rod, a screw, and an upper plate and a lower plate which are arranged vertically; a first end of the screw is sleeved with a first slide block which is threadingly matched with the screw, a second end of the screw is sleeved with a second slide block which is threadingly matched with the screw, the direction of threads of the first end of the screw is contrary to the direction of threads of the second end of the screw; the first slide block and the second slide block are slidingly connected to the lower plate; the first slide block is hinged to the lower end of the first lifting rod, and the second slide block is hinged to the lower end of the second lifting rod; the center of the first lifting rod and the center of the second lifting rod are crossed and hinged; the upper ends of the first lifting rod and the second lifting rod are slidingly connected to the upper plate. The screw is rotated and drives the first slide block and the second slide block to move left and right, and then the upper plate and the second plate are closed up or separated, and the height can be adjusted.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a vertebral body fusion device. Background technique [0002] In daily life, cases of vertebral body damage due to tumors, fractures, infections, etc. occur from time to time. When treating these patients, the current method used is to implant a fusion device between the damaged vertebral bodies to make the bone tissue produce Crawling substitutes to repair the damaged vertebral body. However, the height of the traditional vertebral body fusion cage is fixed, and the height of the intervertebral body of the human body varies from person to person. It is impossible to adjust the height of the vertebral body fusion cage to suit the different needs of different patients. Intervertebral height, so that the intervertebral height of the human body cannot be fully applied to the vertebral fusion device, which affects the therapeutic effect. Contents of the invention [0003] Based ...
