Description

Vertebral canal internal fracture restorer

Technical Field

The invention relates to an interventional medical instrument, in particular to a vertebral canal fracture restorer.

Background

Thoracolumbar fracture refers to the breakdown of thoracolumbar bone continuity due to external force. This is the most common spinal injury. In young and middle-aged patients, high-energy injury is the main injury factor, such as car accidents, high-altitude falling injury and the like. The old patients have osteoporosis, and the injury factors are low-violence injuries such as slipping, falling and the like. The nerve function injury is frequently combined by thoracolumbar fracture patients, and because the injury-causing factors are high-energy injuries basically, other visceral organ injuries are frequently combined, great difficulty and challenge are brought to treatment, a better method is to carry out posterior surgery, but the posterior surgery cannot effectively reset bones in a vertebral canal. The most common method in the existing treatment is to design a restorer for the restoration of a vertebral canal bone block, wherein the restorer mainly adopts an L-shaped restorer in the treatment, but the L-shaped restorer cannot be finely adjusted and depends on the personal experience of a doctor, so that the restoring effect is often poor when the doctor with insufficient experience operates.
