Abstract

The connection kit of the subcutaneous elastic spinal internal fixation system, including the prying block, the longitudinal rod locking screw and the pedicle locking screw; the pedicle screw hole on the prying block is a stepped hole with a large upper part and a smaller one, which runs through the prying block The upper and lower end surfaces of the prying block, the pedicle locking screw hole penetrates from the rear wall of the prying block to the pedicle screw hole, the longitudinal rod hole penetrates from the rear wall of the prying block to the front end of the prying block, and the longitudinal rod locking screw hole The upper end surface of the prying block penetrates into the longitudinal rod hole; the longitudinal rod locking screw is installed in the longitudinal rod locking screw hole; the pedicle locking screw is installed in the pedicle locking screw hole. The present invention realizes the elastic fixation of the posterior thoracolumbar spine through the principle of prying and resetting. The prying block is compact in structure and can be placed under the skin of the patient. Compared with the thoracolumbar spinal external fixator placed outside the skin, its postoperative care is simple, has little impact on the daily life of the patient, and reduces the occurrence of local skin and soft tissue infections Rate.

Description

technical field [0001] The invention relates to an orthopedic surgical instrument, in particular to a surgical instrument for the surgical treatment of thoracolumbar fractures, restoring the height of the vertebral bodies of thoracolumbar fractures, and realizing the elastic fixation of the subcutaneous pedicle screw-rod system in posterior thoracolumbar surgery, especially a subcutaneous surgical instrument. Connection kit for elastic spinal fixation systems. Background technique [0002] Thoracolumbar fractures are common in clinical practice, involving loss of vertebral body height or spinal canal stenosis, and the treatment methods are mostly surgery. The main purpose of the operation is to restore the height of the vertebral body and the biomechanical stability of the spine, and at the same time strive to reduce the surgical trauma and the incidence of postoperative complications as much as possible. [0003] At present, for thoracolumbar fractures with unstable spine,...
