AI Technical Summary

Problems solved by technology

If the screw is placed on this basis, the pedicle will lose more bone mass, which will reduce the pull-out strength of the screw
At the same time, the operator needs to have a good feel and skills, which is dangerous, and the operation time is long and inconvenient to use.

Abstract

The invention relates to a thoracic vertebra pedicle screw path detector which is characterized by comprising a handle (1), and the front end of the handle is connected with an arc-shaped smooth proof stick (2). The thoracic vertebra pedicle screw path detector has the advantages that the structure is simple, using is convenient, the detector is used in internal fixation of a thoracic vertebra pedicle screw, operation efficiency can be obviously improved, operation difficulty and complications are reduced, and operation wounds of a patient are reduced.

Description

technical field [0001] The invention relates to a medical instrument for thoracic vertebral pedicle screw internal fixation, in particular to a thoracic vertebral pedicle screw track detector used as an instrument for exploring the thoracic posterior pedicle screw internal fixation. Background technique [0002] In recent years, with the development of transportation and construction industry, the incidence of thoracic trauma has been increasing year by year. When the thoracic spine is subjected to flexion, lateral flexion, or rotational violence during thoracic fracture or fracture dislocation, the three-column structure of the thoracic spine is destroyed, the stability of the spine is lost, or the spinal cord is damaged to varying degrees. Early reduction and decompression are performed, and pedicle screws are used Fixing and reconstructing the stability of the thoracic spine is of great significance for alleviating secondary spinal cord injury, promoting the recovery of s...
