Abstract

The invention discloses a locking occipital plate with adjustable width, which comprises an arch-bridge-shaped occipital plate, a connecting seat, an occipital screw, a C-shaped ring and a snap ring. Adjustment holes are provided on the two side wings of the arch-bridge-shaped occipital plate, and the connecting seat and the adjusting hole Slidable connection, the snap ring is stuck on the outside of the connecting seat, there are several fixing holes in the middle of the arch-shaped occipital plate, the occipital screws penetrate the fixing holes, and the C-shaped ring is set in the fixing holes and sleeved on the head of the occipital screw. The C-shaped ring can move in the fixing hole. The invention solves the problem that multiple specifications of the existing occipital plate need to be prepared for surgery, which increases the production cost and operating cost; it solves the problem that the connecting rod has a large degree of bending during the operation, and repeated bending and adjustment will cause the fatigue stress concentration of the connecting rod. The problem of easy fracture and failure; solves the problem of screw loosening after occipital plate surgery, reduces the risk of secondary surgery, and enables patients to obtain a better postoperative experience.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, particularly to a width adjustable lock occipital plate. Background [0002] Since the long-term life of human beings, there have been quite a lot of spinal fractures, tumors, infections and degenerative diseases related to spinal diseases, with the continuous development and exploration of modern medicine, the treatment of spinal diseases that plague human life has been well improved, and the products and technologies that deal with surgical treatment in this regard are quite perfect and mature. For example, occipital bone plates, occipital bone plates are mainly used in occipital-cervical fusion bone surgery, mainly with occipital bone screws, titanium rods, cervical spine pedicle screws and other implants for surgical fixation of traumatic cervical vertebral fractures. [0003] The existing occipital-neck fusion system is mainly divided into two types: the integrated occipital bone ...
