Document Type and Number:
WIPO Patent Application WO/2023/130872
Kind Code:
A1
Abstract:
A universal bending section assembly (284), a surgical instrument (28), and a split-type surgical device (20). Each bending section (2843) comprised in the universal bending section assembly (284) is disk shaped. Each bending section (2843) comprises a first face (2844) and a second face (2845) which are opposite to each other, wherein the first face (2844) comprises a first inclined face (2846) and a second inclined face (2847) which are symmetrical to each other, and a protrusion structure (2850) is provided between the first inclined face (2846) and the second inclined face (2847); the second face (2845) comprises a third inclined face (2848) and a fourth inclined face (2849) which are symmetrical to each other, and a recess structure (2851) is provided between the third inclined face (2848) and the fourth inclined face (2849); and the first inclined face (2846) has the same inclination direction as the third inclined face (2848), and the second inclined face (2847) has the same inclination direction as the fourth inclined face (2849). Two adjacent bending sections (2843) are connected to each other by means of the first face (2844) and the second face (2845), the protrusion structure (2850) being embedded in the recess structure (2851). A plurality of bending sections (2843) are located between a vertebra front end (2841) and a vertebra rear end (2842). In this way, the universal bending section assembly (284) can be bent in all directions, such that the process of surgical operation is not limited by bending direction.
