Abstract

The invention relates to a field atlas pedicle screw guide. The field atlas pedicle screw guide is composed of a main body casing and a positioning bracket. The main body casing is a cylinder with rounded corners at the front end. The main body casing is provided with a central hole through the casing. The front end of the main body casing is provided with a circular drill hole. The positioning bracket is composed of connecting rods, support rods and positioning rods. The connecting rod is a cylindrical rod, the head of the connecting rod is fixedly connected with the casing surface of the main body, and the tail part is connected with the upper end of the supporting rod. The support rod is a cylindrical rod, and the lower end of the support rod is connected with the tail of the positioning rod. The positioning rod is a cylindrical rod, and the front end of the positioning rod is provided with a positioning point. Its advantages are: easy to operate, safe and reliable to use, making the implantation of the fixture more accurate, reducing the rate of surgical errors, reducing the number of needle insertions and X-ray radiation, reducing the pain caused to patients, shortening the operation time, and improving security.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a field atlas pedicle screw guide. Background technique [0002] Since Boucher successfully fixed the lumbosacral joint with long screws through the lamina and pedicle to the vertebral body in 1959, transpedicular spinal fixation has been widely used in the world and has become the most commonly used internal fixation in spinal surgery. method. In recent years, with the continuous deepening of people's understanding of this technology, the scope of application has gradually expanded, and more and more pedicle screw technology has been used in the treatment of thoracic spine and even cervical spine diseases. The technical key of transpedicular internal fixation is to master the screw entry point and angle. Due to the complex anatomical structure of the spine, incorrect screw insertion can often lead to serious complications, such as rupture or penetration of the pedi...
