Abstract

A sleeve combination appliance for bilateral transpedicular surgery comprises sleeves, positioning needles, a connecting cross bar, bone grafting funnels and handle parts. Each handle part comprises a handle and a handle end. The handle ends are connected with the sleeves through threaded structures; the bone grafting funnels are arranged on the tops of the sleeves through the handle ends; the bottoms of the sleeves are provided with sawtoothed edges; the sides of the sleeves are provided with connecting heads which are of raised structures, and the connecting cross bar is provided with slide ways and connecting sockets, the connecting sockets are connected with the connecting heads, so that the sleeves are connected with the connecting cross bar, and by the adjustment of the slide ways, the connecting sockets and the connecting heads, the distance between the two sleeves and the angles of the sleeves can be controlled; puncture needles are arranged on the bottoms of the positioning needles and used along with the sleeves; and the outsides of the sleeves and the positioning needles are provided with scales. The sleeve combination appliance for bilateral transpedicular surgery is used for simultaneous bilateral operation, has a reasonable structure, is easy to operate, can quantify an operation and also can coordinate the consistency of the operation of doctors.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to a combined instrument for bilateral pedicle surgery sleeves. Background technique [0002] With the aging of the population, the incidence of osteoporosis is increasing year by year. In addition, traffic accidents are increasing and thoracolumbar fractures are increasing year by year. Thoracolumbar compression fractures, resulting in loss of vertebral body height and changes in force lines, will inevitably lead to instability of the spine, and vertebral body reduction must be performed. [0003] The traditional posterior short-segment pedicle screw internal fixation technology has achieved good results in the treatment of thoracolumbar fractures, but with clinical practice and follow-up, it has been found that the reduction and fixation are not good enough or the intervertebral disc is difficult to reset. For those with increased height, the reset of the injured ver...
