A new type of spinal deformity corrector

Abstract

The invention discloses a novel spinal deformity corrector. The key points of its technical scheme are that it includes an upper bracket rod and a bracket foot, the upper bracket rod and the bracket foot are integrally formed, the upper bracket rod is mirrored on both sides, and the upper brackets on the left and right sides There is a hydraulic mechanism at the joint of the rod, the hydraulic mechanism is used to control the opening and closing of the support rod, and there is a guide mechanism for assisting the opening and retracting of the support legs on the left and right sides of the support legs, and there is a horizontal connection part at the support legs; The hydraulic mechanism includes a hydraulic cylinder, a piston and a driver. The piston is arranged in the hydraulic cylinder. The driver is used to drive the piston to rise or fall. The pressure chambers are connected by hoses, and the orthotic adopts a hydraulic method to control the opening or closing of the struts, so as to precisely control the precise displacement of the support rods.

Description

technical field [0001] The invention relates to a novel spinal deformity corrector. Background technique [0002] With the development of spinal surgery technology, posterior spinal osteotomy and correction is gradually being widely used in clinic, which can be used to correct ankylosing spondylitis, congenital abnormal vertebral body development, old fractures, spinal tuberculosis and vertebral body tumors and other related diseases. It can also be used to complete the treatment of severe scoliosis. The primary goal of osteotomy and orthopedic treatment for spinal deformity is to maintain a reasonable osteotomy in order to maintain the balance in the three-dimensional direction of the spine, and at the same time correct the deformity to achieve better fusion, prevent the further progression of the deformity, and improve the appearance and quality of life of the patient. When performing spinal osteotomy, the surgeon needs various tools to complete various surgical operation...

AI Technical Summary

Problems solved by technology

[0003] 1. Since the hand wheel is used to rotate and the gear mechanism is driven by the rotating shaft, the gear drives the rack to move back and forth to promote the clips to be folded and opened. The rotation of the hand wheel must have a force towards the patient's body to be able to rotate effectively, so it has a certain impact on the spine. The pressure is not conducive to the surgical rehabilitation of the spine;

[0004] 2. The transmission mechanism of the gear and the rack is displaced in units of a tooth pitch, so the distance accuracy of the bracket displacement is limited by the tooth pitch, which is not conducive to precise control
