Abstract

The invention is suitable for the technical field of medical apparatus, and provides a snake skeleton-like assembly. The snake skeleton-like assembly comprises a plurality of snake skeleton-like unitswhich are in sequential connection, and an elastic body, wherein the adjacent snake skeleton-like units are connected through a rotating structure at the circumferential direction position; and the adjacent snake skeleton-like units are connected in a manner being free from disengaging at the circumferential direction position. The snake skeleton-like assembly has connection of elastomers, so that the snake skeleton-like units are not disengaged in the axial direction and the radial direction; and the rigidity of the elastic bodies is small, so that the rigidity of the snake skeleton-like assembly is not increased redundantly. Besides, according to the length of the snake skeleton-like assembly, the snake skeleton-like units of corresponding quantity can be selected, so that the situationthat the length of the snake skeleton-like assembly depends on the length of a selected metal cylinder can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a snake bone component and an endoscope. Background technique [0002] As an important part of the endoscope, the snake bone is usually used as the bending part of the endoscope, and the bending and turning of the endoscope lens end is realized by pulling the traction rope placed inside the snake bone. [0003] In the prior art, there are usually two forms of snake bones: [0004] One is the rivet connection type. The manufacturing and assembly process of rivet riveting connection is very complicated, and the technical requirements for workers are high, and riveting defects are extremely prone to occur. [0005] The other is the riveted snake bone, as in the patent CN107334449A, the connection between adjacent parts is realized through the connection pair of the snap ring hinge structure, and the two sides of the connection pair are respectively formed with cut corne...
