Abstract

The invention discloses an anterior cervical fusion device comprising an upper wall, a lower wall and a columnar body connected with the upper wall and the lower wall. A first screw hole is formed in the upper wall, the columnar body is provided with a filler opening which is through in the front-back direction, at least a second screw hole and a third screw hole are formed between the upper wall and the filler opening, and fixing grooves are formed in the two sides of the columnar body. The screw holes are formed in the upper wall of the fusion device, so the fusion device and an implantation device can be well fixed. Besides, the fixing grooves are formed in the two sides of the columnar body of the fusion device respectively and matched with a clamping arm of the implantation device, and accordingly it is further guaranteed that the fusion device is well fixed and prevented from loosening and moving.

Description

technical field [0001] The invention relates to a fusion device, in particular to an anterior cervical fusion device. Background technique [0002] When performing cervical spine surgery, it is necessary to use tools to hold the fusion cage and send it into the cervical spine. The existing fusion cage generally does not have a specific holding position, and it is easy to loosen and shift when using tools to send the fusion cage into the cervical spine. into the predetermined location. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide an anterior cervical fusion device that can be stably fixed during use. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] An anterior cervical fusion device, comprising an upper wall, a lower wall and a columnar body connecting the upper wall and the lower wall, wherein, [0006] The upper wal...
