Therefore, a new intervertebral processor is specially designed to achieve different degrees of support and expansion effects on the intervertebral space, which is convenient for the surgeon to perform surgical operations, improve work efficiency, and reduce surgical risks.

[0038] like Figure 1 , Figure 2 As shown, the device includes a handle end 1, a processing end 2 and a support end 3, wherein the processing end 2 and the support end 3 are integrated into the front end of the handle end 1; and the handle end 1, the processing end 2 and the support end 3 are connected as a whole to form a "T"-shaped structure, which conforms to human hand engineering and is convenient for users to grasp; correspondingly, the handle end is composed of a plurality of cylinders of different sizes, and are evenly arranged in a regular pattern of being thick in the middle and thin at both ends, which can increase the friction between the patient's palm and the handle end, avoid slipping, and also improve the comfort of the operator when using it.

[0039] Correspondingly, the supporting end 3 in this embodiment is two pairs of supporting units 4 arranged side by side, wherein the processing end 2 is arranged in the middle of the two pairs of supporting units 4; correspondingly, an opening mechanism 5 is arranged inside the handle end 1, and the opening mechanism 5 is connected to the two pairs of supporting units 4, and drives the two pairs of supporting units 4 to open the vertebral space and adjust it to an appropriate height.

[0040] See again the attached Figure 2As shown, in the present embodiment, the support unit 4 includes two support plates 41 arranged vertically, and the spreading mechanism 5 includes a supporting movable rod 51, wherein the end of the supporting movable rod 51 is connected to the inner surface of the upper and lower supporting plates 41 through a plurality of connecting rods 512, and correspondingly, one end of the handle end 1 is also connected to the end of the upper and lower supporting plates 41 through the connecting rod 512; wherein the connecting rod 512 involved in the present embodiment is respectively hingedly connected to the handle end 1, the support plate 41 and the supporting movable rod 51; correspondingly, the supporting movable rod 51 can slide back and forth in the chamber inside the handle end 1 and control the supporting plate 41 to be propped up and retracted through a plurality of connecting rods 52.

[0041] In this embodiment, the spreading mechanism 5 further includes a handheld connecting rod 52, wherein one end of the handheld connecting rod 52 is fixedly disposed in the handle end 1, and the other end is fixedly connected to the end of the supporting moving rod that is not provided with a connecting rod;
