Abstract

The invention discloses a spine nail rod hook device which comprises a connection rod. A spine fixing nail, a spine universal nail and multiple connection hooks are fixed to the connection rod, the spine fixing nail, the spine universal nail, the connection hooks and the connection rod are fixed through fixing screws, and the sides of the connection hooks are provided with thread holes matched with vertebra pedical nails. The spine nail rod hook device is simple in structure, high in safety, and capable of meeting clinic requirements and reducing soft tissue interference to the maximum. When the spine nail rod hook device is in use, the spine fixing nail and the spine universal nail can be rapidly screwed in, the purpose of connecting spongiosa with cortical bone more firmly can be achieved, meanwhile, the lamina hooks can be effectively positioned due to the fact that the sides of the lamina hooks are provided with the thread holes, and use is convenient.

Description

technical field [0001] The present application relates to an orthopedic implant medical device, in particular to a spinal nail, rod and hook device for treating vertebral body fractures and dislocations. Background technique [0002] Usually human spinal diseases, slips, dislocations, tumors and fractures for loss of motion function are injured by surgical implantation to restore the injured site. [0003] Spinal screw-rod-hook system is fracture repair, and it is also a new technology of modern fracture fixation. It adopts indirect fracture reduction technology, combined with pulling and fixing to maintain fracture reduction, so that surgical exposure and soft tissue stripping are minimized. Can improve fracture healing effect better. [0004] Spinal screw-rod-hook system can effectively treat various cases of spinal vertebral posterior approach and reduce the incidence of complications. [0005] Spinal screw-rod-hook system generally includes a horizontal connecting rod ...
