By applying the technical solution of this embodiment, it is possible to continuously measure the heights at different positions in the gaps between human vertebral bodies, thereby improving measurement efficiency. And based on the measured height and depth, the height and longitudinal length dimensions of the applicable prosthesis 60 can be obtained, thereby determining the model and specifications of the prosthesis 60 . Further, the frame body 10 includes a frame body 11 extending in the horizontal direction. There are two measuring parts 20 . The two measuring parts 20 are arranged oppositely on the upper and lower sides of the rack body 11 . The two measuring parts 20 can float in the vertical direction relative to the rack body 11 to approach or move away from each other. The arrangement of two upper and lower measuring parts 20 enables the upper measuring part 20 to contact the upper human vertebral body, and the lower measuring part 20 to contact the lower human vertebral body, thereby improving the accuracy and efficiency of height measurement. The intervertebral prosthesis implantation tool also includes a clamping structure movably arranged on the frame body 11. The clamping structure is clamped on the outside of the two measuring parts 20, and the clamping structure moves to drive the two measuring parts 20 closer to each other. . This allows the operator to drive the two measuring parts 20 to float through the clamping structure, which facilitates the adjustment of the measuring parts 20 during height measurement.

As shown in Figures 1 to 3, the rack body 11 is provided with a rotating shaft. The clamping structure includes a first clamping part 41 and a second clamping part 42 arranged in a cross. The first clamping part 41 and the second clamping part 42 are both penetrated through the rotating shaft and are rotatably arranged on the frame body 11 .

The structure of the clamping structure is simple. The two measuring parts 20 can be clamped by the first clamping part 41 and the second clamping part 42 arranged crosswise, and the first operating handle 411 and the second operating handle 421 can be driven close to each other. The two measuring parts 20 are driven close to each other.

In this embodiment, before moving the measuring part 20 to the gap between the two human vertebral bodies, the two measuring parts 20 are driven close to each other through the clamping structure, so that the two measuring parts 20 can enter the two spaces more smoothly. Within the spaces between the vertebrae of an individual's body. One measuring part 20 is movable relative to the first clamping arm 412 , and the other measuring part 20 is movable relative to the second clamping arm 422 .
