Adjustable fusion cage device

Abstract

The invention relates to an adjustable fusion cage device which comprises a hose, a bevel gear, a gear seat, a screw rod and a fusion cage body, wherein the fusion cage body rotates along with the screw rod to ascend and descend; the bevel gear is meshed on the gear seat; the gear seat is connected with the fusion cage body; one end of the hose is connected with the screw rod; a through hole is formed in the bevel gear; the bevel gear sleeves the hose through the through hole. The hose is clamped by a clamp to rotate, the screw rod is driven to rotate, and then the screw rod is driven to rotate, so that the height of the fusion cage body ascending and descending can be changed, height adjustment can be achieved, and the adjustable fusion cage device can be applicable to different intervertebral heights of different patients; the bevel gear can be clamped by another clamp to rotate and drives the gear seat meshed with the bevel gear to rotate, so that overall angle adjustment of the fusion cage can be achieved, and the treatment mounting requirement on the mounting angle of the fusion cage can be met.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an adjustable 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. The intervertebral height cannot make the intervertebral fusion device fully adapt to the intervertebral height of the human body, and the angle of the fusion device after being loaded into the cone cannot be adjuste...
