The interbody fusion cage body 100 is arranged in the clamping cavity 501, the hook 511 is inserted into the connecting hole 140 of the body 100, the hook 511 extends into the connecting hole 140 along the cylindrical surface 110, the hook 511 abuts against the cylindrical surface 110, and the stopper 521 abuts against the cylindrical surface 110, so that the interbody fusion cage body 100 is fixed in the clamping cavity 501.

The side wall of the housing 200 is provided with a first long slot 240 and a second long slot 250, and the first long slot 240 and the second long slot 250 extend along the front-back direction. The first long slot 240 communicates the hollow cavity 210 with the outside, a first sliding block 512 is disposed on the outer wall of the first clamping member 510, the first sliding block 512 is slidably disposed in the first long slot 240, and the first sliding block 512 extends out of the first long slot 240. The first sliding block 512 is pushed to slide back and forth in the first long slot 240, so that the first clamping member 510 moves back and forth. The second slot hole 250 communicates the hollow cavity 210 with the outside, a second slider 522 is disposed on the outer wall of the second clamping member 520, the second slider 522 is slidably disposed in the second slot hole 250 in the front-back direction, and the second slider 522 extends out of the second slot hole 250. The second sliding block 522 is pushed to slide back and forth in the second slot hole 250, so that the second clamping piece 520 moves back and forth.

A slide groove 260 is provided on the top surface of the housing 200, and the slide groove 260 extends in the front-rear direction. The wedge block 600 has a wedge structure with a small front and a large rear, and the wedge block 600 is slidably disposed on the top surface of the housing 200. The rear side of the wedge block 600 is provided with a sliding block 610, the sliding block 610 is slidably disposed in the sliding groove 260 back and forth, and the sliding block 610 is pushed to slide back and forth in the sliding groove 260, so that the wedge block 600 slides back and forth. The bottom surface of the housing 200 is provided with anti-slip teeth 270, and the anti-slip teeth 270 are located at the front of the housing 200. When the front end of the implant device is inserted into the spine of a human body, the anti-slip teeth 270 on the bottom surface of the shell 200 prevent the shell 200 and the spine from sliding relatively, the sliding block 610 is pushed forward to insert the front end of the wedge block 600 into the spine of the spine, and as the wedge block 600 gradually moves forward, the intervertebral space of the spine is continuously enlarged, thereby facilitating the intervertebral fusion device body 100 clamped by the clamping mechanism at the front end of the implant device to be implanted into the spine.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that the present invention is not limited to the details of the embodiments shown and described, but is capable of numerous equivalents and substitutions without departing from the spirit of the invention as set forth in the claims appended hereto.
