Benefits of technology

This patent describes a device called a pedicle screw locking system for connecting rods in a structure. It consists of a reducer tube and a locking driver. Inside the reducer tube there are two gears on its inside and a reduction sleeve around it. There also have fingers at the ends of these gears. These fingers fit into slots in the reduction sleeves, which hold them securely. When the reducer tube is connected to the rod, it moves along the rod's axis. Locking drivers connect to the reducer tube and move it backward when locked.

Problems solved by technology

This patent describes different methods used during medical surgeries to repair damaged parts of the spine. One method involves replacing all the affected area with artificial materials like plaster or fiberglass, creating space around it, then attaching them together using bolts or screws. Another method involves using prosthetic devices made of synthetic polymers like silicon rubber or polysulfonimide.

Abstract

A pedicle screw locking system includes a reduction tube and a locking driver. The reduction tube includes an inner shaft, a pair of grips, a reduction sleeve, and a rotatable tube. The inner shaft has a threaded end and reduction arms distally extending from the threaded end. Each grip of the pair of grips has a finger configured to engage the receiver of a pedicle screw. The reduction sleeve and the rotatable tube are disposed over and coaxially aligned with the inner shaft. The rotatable tube is coupled to the reduction sleeve. The rotatable tube moves the reduction sleeve relative to the reduction arms. The locking driver includes a threaded portion and a blunt tip. The threaded portion is configured to thread into threads in the receiver of the pedicle screw until the blunt tip locks the receiver of the pedicle screw.
