Embodiment
[0033] Such as Figure 1-Figure 7 As shown, the present invention provides an anterior cervical spine fixation structure, which includes a titanium plate 1 , screws 2 and limit buckles 3 . The titanium plate 1 is provided with fixing holes 11 . The fixing hole 11 allows the screw 2 to pass through, so that the screw 2 can be tightened to the bone, and then the screw 2 can fix the titanium plate 1 to the bone. The screw 2 is arranged in cooperation with the fixing hole 11 . The limit buckle 3 is slidably arranged on the titanium plate 1 . The limit buckle 3 is provided with an elastic piece. The elastic force of the elastic member is used to push the limit buckle 3 so that one end of the limit buckle 3 slides to the opening of the fixing hole 11 .
[0034] When the anterior cervical fixation structure of the present invention is used, the screw 2 is inserted through the fixing hole 11 and the screw 2 is pressed down so that the screw 2 fits into the fixing hole 11 . During...

The invention relates to the technical field of medical instruments, in particular to an anterior cervical fixing structure. The structure comprises a titanium plate, a screw and a limiting buckle. The titanium plate is provided with a fixing hole. The screws are matched with the fixing holes. The limiting buckle is arranged on the titanium plate in a sliding mode. The limiting buckle is provided with an elastic piece. The elastic force of the elastic piece is used for pushing the limiting buckle so that one end of the limiting buckle can slide to the opening of the fixing hole. During use, a screw penetrates through the fixing hole and is pressed down, so that the screw is matched with the fixing hole. In the process, the nut gradually extrudes and pushes the limiting buckle to slide, so the nut can pass through the limiting buckle and gradually slide into the fixing hole. After the nut is contained in the fixing hole, the limiting buckle rebounds to the opening of the fixing hole under the action of the elastic piece, and then the nut is limited in the fixing hole. And the limiting buckle automatically pops up after the screw is put into the fixing buckle, so that the screw is effectively limited in time, and the screw is prevented from loosening.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an anterior cervical fixation structure. Background technique [0002] The screw locking method of the existing anterior cervical fixation system is to put the screw into the fixed titanium plate, and then rotate the rivet or the knob on the fixed titanium plate, so that the rivet or the knob fixes the screw. It is cumbersome to use, and once the rivets or locking buckles are not rotated in place, the screws are likely to loosen; during use, the rivets or locking buckles may be forced to rotate, thereby causing the screws to loosen. These may cause medical malpractice. Contents of the invention [0003] The purpose of the present invention is to provide an anterior cervical spine fixation structure, which can well avoid screw falling off. [0004] Embodiments of the invention are achieved through the following technical solutions: [0005] An anterior cervical spine ...
