Problems solved by technology

[0002] When performing intervertebral surgery, adjacent vertebrae need to be fixed. The existing fixation method is to open a larger wound on the patient and directly fix the screws and pull screws. Too large wounds are not conducive to postoperative rehabilitation of patients, and Complications are prone to occur, and longer postoperative recovery time is required. For this reason, the present invention provides a minimally invasive spinal internal fixation system to solve the above problems

Abstract

The invention discloses a minimally invasive spine internal fixation system, which comprises a minimally invasive channel establishing and expanding assembly, a drilling assembly, a plurality of screw assemblies, a screw assembly mounting mechanism, a plurality of pull rods, a pull rod inserting assembly and a plurality of fastening nails, wherein by virtue of the minimally invasive channel establishing and expanding assembly, a minimally invasive channel is established on the back of a patient and is expanded to set sizes; the drilling assembly enters the minimally invasive channel, and by virtue of the drilling assembly, a threaded hole is drilled in a preset vertebra position; each of the screw assemblies comprises a screw and a connecting block; the upper sides of the screws are rotatably connected to the connecting blocks; a first through hole is each formed in the connecting blocks; screw threads are arranged on the inner sidewalls of the first through holes; second through holes are formed in the sidewalls of the connecting blocks; by virtue of the screw assembly mounting mechanism, the screws are screwed into the threaded hole; each of the pull rods can be simultaneously inserted into the second through holes of the plurality of connecting blocks; by virtue of the pull rod inserting assembly, a pull rod is inserted in the second through holes of the plurality of screw assemblies fixed to vertebra; and the plurality of fastening nails are arranged in the first through holes for pressing the pull rod. With the application of the minimally invasive spine internal fixation system provided by the invention, vertebra fixation can be completed with a relatively small incision.

Description

technical field [0001] The invention relates to a minimally invasive spinal internal fixation system. Background technique [0002] When performing intervertebral surgery, adjacent vertebrae need to be fixed.
