Embodiment Construction

[0024] The idea, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts belong to The protection scope of the present invention. In addition, all the connection / connection relationships involved in the patent do not simply refer to the direct connection of components, but mean that a better connection structure can be formed by adding or reducing connection accessories according to specific implementation conditions. The orientation descriptions of up, down, left, right, etc. involved in the present invention are only relativ...

Abstract

The invention relates to the technical field of transmission devices and provides a snake bone. The snake bone comprises a snake bone body and a traction part, the snake bone body comprises a head endconnector, a snake-bone middle portion and a tail end connector, wherein the snake-bone middle portion comprises a plurality of snake bone gaskets, supporting pieces are arranged between each two adjacent snake bone gaskets, and the traction part is used for dragging the snake bone body for bending movement. Compared with the scheme that multiple scleromeres are connected with one another in a riveted mode in the prior art, the snake bone has the advantages that the structures of the snake bone gaskets and the supporting pieces are more simple, so that installation and maintenance are easier;under the circumstance that the bending angles needed by the whole snake bone are the same, the multiple snake bone gaskets can be arranged in the same length range of the snake-bone middle portion,so that multiple gaps are formed, and bending space which is needed is arranged among the multiple snake bone gaskets respectively, so that the size of one single gap is reduced, and then adjusting and control are more precise; the bending degrees among adjacent snake bone gaskets are reduced, and then the shape is more smooth.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to a snake bone. Background technique [0002] Snake is a transmission device commonly used to control the rotation direction of the endoscope. Usually, the endoscope is set at one end of the snake, and the rotation of the endoscope in the corresponding direction is realized through the bending of the snake. In the prior art, the snake bone usually consists of several joints connected in series to form the main body of the snake bone. The joints are riveted with each other and pulled by ropes to make them produce corresponding bending movements. This scheme has complex joint structures and is difficult to install. Larger gaps are needed between the joints to achieve a large angle of bending of the snake bone as a whole, which makes the overall structure not compact enough, the degree of bending between the joints is large, and the flatness is poor. [0003] Therefore, ...
