AI Technical Summary

Technical Problem

In existing technologies, traditional rod and plate systems for spinal fixation have problems such as large space occupation, severe irritation to soft tissues, insufficient fixation strength, easy loosening of screws, and easy breakage of plates, especially in cases of complex vertebral defects where they are difficult to provide effective support.

Method used

A thoracic and lumbar anterior approach bone plate was designed, which adopts a three-hole or four-hole structure, with locking screws in the fixation holes, and first and second grooves and anti-dislodgement structure at the screw nut. The plate body is designed to fit the vertebral anatomy, and utilizes the high-density bone structure in the endplate area, with a coating to enhance fixation strength.

Benefits of technology

It effectively reduces irritation to soft tissues, lowers postoperative complications, improves fixation strength, reduces the risk of screw loosening and plate breakage, and provides reliable spinal support.

Abstract

The utility model discloses a kind of thoracolumbar spine anterior approach bone plate, comprising: plate body, the plate body both ends end portion is equipped with the N fixed holes of through plate body, 3≤N≤4, and integer, locking screw is equipped in the fixed hole;First recess is separately equipped in the fixed hole end portion close to locking screw nut, second recess is equipped in the fixed hole side, first recess and second recess are communicated and cross at edge, anti-escape nail is equipped in the second recess, and the anti-escape nail is used to limit screw;The structure has while keeping plate body certain fixed intensity, effectively reduce the volume of plate body, reduce the irritation to surrounding soft tissue, without pre-bending, bending in operation, can effectively reduce intraoperative operation time, reduce the risk of the decline of plate body mechanical property due to bending, while avoiding the characteristics of plate body fracture or screw-plate body interface failure.
