Universal vertebral body reduction device for orthopedic vertebral column surgery

Abstract

A universal vertebral body reduction device for orthopedic vertebral column surgery comprises a first reduction bar and a second reduction bar. The first reduction bar and the second reduction bar are connected via a connecting device, a first universal joint is fixedly welded or sleeved on the first reduction bar, and a second universal joint is fixedly welded or sleeved on the second reduction bar; one end of the connecting device is fixedly welded or inserted in the first universal joint, and the other end of the connecting device is adjustably connected into the second universal joint via a fastening device; and bottom ends of the first reduction bar and the second reduction bar are respectively fixedly connected with a first clamping device and a second clamping device which are used for being connected with an orthopedic internal fixing apparatus. The universal vertebral body reduction device is a surgical instrument which is simple and labor-saving in operation, fast and reliable in temporary fixation, and sophisticated and accurate in surgical reduction, and can meet orthopedic clinical requirements of temporary fixation and surgical reduction between bone fracture sections.

Description

[0001] technical field [0002] The invention relates to an orthopedic universal reducer, in particular to a vertebral body universal reducer used in orthopedic spinal surgery, belonging to the technical field of medical instruments. [0003] Background technique [0004] With the advancement of medical technology, the operation of reduction and fixation after the complete resection of diseased or deformed vertebral bodies has been implemented clinically. During the implementation of this type of operation, reliable temporary fixation and accurate surgical reduction between the upper and lower segments of the diseased vertebral body or deformed vertebral body to be completely resected is an important part of the successful operation. [0005] At present, when this type of operation is performed clinically, the existing spinal internal fixator is used for temporary fixation between the upper and lower vertebral bodies of the diseased vertebral body or deformed vertebral body...

AI Technical Summary

Problems solved by technology

[0012] However, in the process of installing orthopedic spinal internal fixator during orthopedic spinal internal fixation surgery, temporary fixation and surgical reduction are required between the two bone segments after fracture or bone resection. At present, it has not been found clinically that can satisfy temporary fixation and surgical reduction. The required orthopedic surgical tools, which will take a long time for the operation, increase the risk of the operation, and affect the quality of the operation
