Problems solved by technology

[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 fusion cage cannot fully adapt to the intervertebral height of the human body, and the angle of the fusion cage after being installed in the cone cannot be adjusted

Embodiment Construction

[0028] Such as Figures 1 to 5 As shown, an adjustable fusion device includes a hose 10, a bevel gear 20, a gear seat 30, a screw 40, and a fusion body 50a (50b) (50c) that can be raised and lowered with the rotation of the screw 40. The conical The gear 20 is meshed on the gear seat 30, the gear seat 30 is connected to the fuser body, one end of the hose 10 is connected to the screw 40, the bevel gear 20 is provided with a through hole 210, And the bevel gear 20 is sheathed outside the hose 10 through the through hole 210 .

[0029] The adjustable cage device clamps the flexible tube 10 through the clamp and rotates to drive the screw 40 to rotate, thereby driving the height of the cage body that rises and falls with the rotation of the screw 40 to achieve height adjustment, and is suitable for different intervertebral joints of different patients. Height: The bevel gear 20 is clamped and rotated by another clamp, and the bevel gear 20 drives the gear seat 30 meshed with it ...

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...
