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. Large gaps are required 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

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...

The present invention relates to the technical field of transmission devices, and provides a snake bone, which includes a snake bone body and a traction part. As for the spacer, a supporting piece is arranged between two adjacent snake bone spacers, and the traction part is used to pull the snake bone body for bending movement. The structure of the bone spacer and support is simpler, easier to install and maintain. In the case of the same bending angle required for the whole snake bone, more snake bone spacers can be set within the same length range of the middle snake bone, so that More gaps are formed, so that the required bending space is divided between more snake-bone spacers, and the size of a single gap is reduced, so that the regulation is more precise, and the bending degree between adjacent snake-bone spacers is reduced. Smaller for a flatter appearance.
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, ...
