Minimally invasive vertebral body forming positioner for orthopedics department

Abstract

The invention discloses a minimally invasive vertebral body forming positioner for the orthopedics department, and belongs to the technical field of medical instruments for the orthopedics department. The minimally invasive vertebral body forming positioner comprises a positioning part and an operation part; the positioning part comprises a positioning rod, fixed suction cups, a positioning mark and a fixing bolt; the operation part comprises a fixed column, a fixed mark post, a fixed angle ruler and an operation cylinder; the fixed suction cups are fixed to the two ends of the positioning rod; the positioning mark and the fixing bolt are fixed to the positioning rod; the fixed column is fixed to the fixing bolt; the fixed marker post is arranged on the fixed column; the fixed angle ruler is fixed on the fixed marker post; and the operation cylinder is arranged on the fixed marker post through a universal head arranged on the operation cylinder. According to the specificity of the individual vertebral body, the needle inserting point and the needle inserting angle can be accurately determined, so that needle inserting is accurate, the accuracy rate is improved, one-time success is achieved, the damage to the vertebral pedicle due to multiple times of puncture is avoided, the nerve roots are prevented from being damaged, the number of times of fluoroscopy in an operation is reduced, the body of an operator is protected, and the radiation of rays to the body is reduced.

Description

technical field [0001] The invention relates to the technical field of orthopedic medical devices, in particular to an orthopedic minimally invasive vertebroplasty positioner. Background technique [0002] With the prolongation of life expectancy and the continuous increase of the elderly population leading to the advent of the elderly society, fractures caused by osteoporosis, one of the degenerative diseases of the middle-aged and elderly, have become a serious social problem and have attracted much attention. Spine compression fractures caused by osteoporosis have the highest incidence rate between 60-70 years old. Fractures mainly occur in the thoracic and lumbar vertebrae, and T12 and L1 vertebrae are the most common. Osteoporosis can reduce the strength of the vertebral body, so that Normal daily activities will exceed the maximum load of the vertebral body, resulting in a vertebral compression fracture, which is limited to the vertebral body and does not affect the ve...

AI Technical Summary

Problems solved by technology

This positioning method has many disadvantages: 1. There are many times of fluoroscopy during the operation, and the patient and the operator are seriously irradiated.

2. The positioning of the puncture needle in the operation depends on the experience of the operator, and the error is large

3. The puncture needle is easy to damage the nerve root

4. When the operator adjusts the angle of the puncture needle several times, the puncture needle will damage the pedicle and affect the strength of the pedicle
