Abstract

The invention discloses a novel self-rotating spine-distracting internal fixation system comprising a fixed connector block, a connecting sleeve, a screw shaft, screw caps, a rotating adjusting opening, universal pedical screws, adjustable connecting fixer blocks and pedical screw adjusting ribs. The fixed connector block is disposed in the middle of the screw shaft. The connecting sleeve is fixed on two sides of the fixed connector block through the screw shaft. The screw caps are disposed on the upper portions of the adjustable connecting fixer blocks. The rotating adjusting opening is arranged in the right end of the screw shaft. The universal pedical screws are disposed on the lower portions of the adjustable connecting fixer blocks. The pedical screw adjusting ribs are arranged at the upper ends of the universal pedical screws. The novel self-rotating spine-distracting internal fixation system is simple in structure, novel in design, simple to produce and manufacture and convenient to clinically operate. The spine is reduced by self-rotating distraction during locking, with no need for surgical reduction; the system is applicable to open surgeries, minimally invasive surgical therapies and surgical treatment of spinal fracture, spondylolisthesis, scoliosis and spinal tumor and is convenient to popularize and practically use.

Description

【Technical field】 [0001] The invention relates to the technical field of surgical medical instruments, and more specifically, relates to a novel self-rotating distraction spinal internal fixation system. 【Background technique】 [0002] At present, pedicle internal fixation for spinal injuries has been widely used and developed from the United States to Europe and all over the world in the past ten years since it came out in 1987, and various new fixation methods continue to emerge. According to the different connection methods, it is mainly divided into two systems: nail rod and nail plate. The former system is currently widely used and can be used for reduction and internal fixation of spinal fractures, degeneration, spondylolisthesis, spinal tumors, scoliosis, etc. The latter system is mainly used for the treatment of spondylolisthesis. With the deepening of mechanical research, the scope of application gradually crosses and expands. The existing spinal fixation system f...
