Abstract
This utility model discloses a laminar fixation device, comprising: a plate holder, the plate holder including a handheld part, a cylindrical tube fixedly connected to the upper part of the handheld part, two clamping plates elastically connected to one end of the cylindrical tube, a fixation plate clamped between the two clamping plates, and a rod body provided in the hollow part of the cylindrical tube. During use, this utility model can fix the position of the fixation plate through the threaded rod, so there is no need to worry about the fixation plate slipping out of control during the entire implantation process. In addition, the tight connection between the threaded rod and the fixation plate provides a reliable anchor point, so that the fixation plate can be firmly fixed in place throughout the entire operation, thereby greatly improving the accuracy and safety of the operation, solving the problem of possible displacement of the fixation plate in traditional surgery, allowing surgeons to operate with confidence without having to worry about the stability of the fixation plate.
