Abstract

The invention relates to the technical field of medical instruments, in particular to a minimally-invasive thoracolumbar anterior plate, comprising a fixing plate provided with a first through hole and a lock knob; the first through hole allows passage of a fixing part, and the lock knob is provided with a recessed portion that mates with the fixing part; after the fixing part is fixed, the lock knob is rotated such that all the lock knob, except for the recessed portion, is in contact with the fixing part and the fixing part is locked. The problems of the prior art are solved that operating is inconvenient and a fixing plate easily loosens and moves.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a minimally invasive thoracolumbar anterior plate. Background technique [0002] With the development of industry, transportation and population aging, spinal trauma and diseases are on the rise year by year, especially the proportion of patients with thoracolumbar injuries is relatively high. Early anterior fixation had problems such as poor biomechanical properties, complex shape and structure, and technical difficulties. The currently used minimally invasive thoracolumbar anterior plate usually includes a fixing plate and several screws, the fixing plate is provided with screw holes, and the screws pass through the screw holes. During use, after the front end of the screw is fixed to the spine, the head of the screw is limited through the screw hole. [0003] However, in the prior art, the minimally invasive thoracolumbar anterior plate has the following disadvantage...
