Abstract

The invention discloses a percutaneous cervical posterior single-door internal fixation system, which comprises a first fixation piece, a second fixation piece, a traction piece connected with the first fixation piece and the second fixation piece, the first fixation piece and the second fixation piece are respectively provided with a lamina fixation part and a pedicle fixation part, the first fixation piece can be tensioned to the second fixation piece by means of the traction piece. According to the system, by arranging a fixation device formed by vertebra plates which are inserted percutaneously, a single-door operation can be carried out by using a percutaneous endoscopy technology through the traction piece, the percutaneous operation of the single-door operation can be achieved, theoperation trauma to the soft tissue at the back of the cervical vertebra is reduced and the 'single-door' operation is more minimally invasive.

Description

technical field [0001] The invention relates to a percutaneous spinal internal fixation system, in particular to a percutaneous cervical posterior single-door internal fixation system. Background technique [0002] The existing “single-door” technique for the posterior cervical spine needs to cut the skin from the back of the cervical spine, peel off the paravertebral soft tissue and muscles, expose the structure behind the cervical spine, grind off the junction of one side of the lamina and the lateral mass (the side of the door), and the other side of the vertebral body. The single cortex of the lamina is removed (the door axis side), and then opened to the door axis side, and the lamina is kept in the "single door" state by using wire or internal fixation. Compared with percutaneous endoscopic surgery, the existing technology has a large trauma, which increases the risk of wound infection and the incidence of postoperative pain, which in turn increases the postoperative r...
