Minimally Invasive Percutaneous Atlas Posterior Internal Fixation System

Abstract

The invention discloses a minimally invasive percutaneous atlas posterior inner fixing system, which comprises an arc-shaped frame body, two side block screws and a connecting rod, wherein the arc-shaped frame body covers the back neck of the human body; the two side block screws are arranged on an atlas side block; the connecting rod connects the two side block screws; the inner arc shape of the arc-shaped frame body is matched with the radian of the back neck of the human body; four through holes are formed in the arc-shaped frame body, and are respectively a first through hole, a second through hole, a third through hole and a fourth through hole from the left side to the right side; the first through hole, the connecting rod and the fourth through hole are positioned on the same straight line; the second through hole and the third through hole are respectively positioned on the same straight line with the two side block screws. The minimally invasive percutaneous atlas posterior inner fixing system has the advantages that simplicity and compactness are realized; the operation is convenient and reasonable; the operation can be completed by a minimally invasive small cut, so that the operation is faster, more convenient and more effective; the rehabilitation of a patient is promoted.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a minimally invasive percutaneous atlas posterior internal fixation system. Background technique [0002] The atlas, also known as the first cervical vertebra, is circular and consists of an anterior arch, a posterior arch, and two lateral masses. Studies have shown that axial compression is the main cause of atlas fractures. The classification of atlas fractures is as follows: type I injury is a single anterior arch or posterior arch fracture, type II injury is a simultaneous injury to the anterior and posterior structures of the atlas, and type III is a lateral mass injury regardless of whether the anterior and posterior arches are fractured. For the treatment of atlas fractures, Philadelphia traction, cervical collar fixation, posterior C1-2 fusion, and head ring vest external fixation are generally used clinically. For displaced type Ⅰ and type Ⅱ fractures and type Ⅲ fract...
