Transmission structure for endoscope, endoscope and transmission method

Abstract

The embodiment of the invention belongs to the field of endoscopes, and relates to a transmission structure for an endoscope. The transmission structure comprises two groups of traction assemblies, fixing parts and a snake bone, the front ends of the two groups of the traction assemblies are fixedly connected with the snake bone at multiple connecting positions, the two groups of the traction assemblies are opposite to the connecting positions of the snake bone and mutually matched to drive the snake bone to change the curvature; and the fixing parts are arranged at the rear ends of the traction assemblies, and the two groups of the traction assemblies are locked at a preset position. The invention further relates to an endoscope and a transmission method. According to the technical scheme, the two groups of the traction assemblies can be correspondingly and oppositely fixed to the snake bone at multiple positions, thus special-shaped parts of the traction assemblies are prevented in the bending process, a rotating angle of a matching endoscope is accurately adjusted, two groups of adjusting parts are locked through the fixing parts, and thus the rotating angle of the endoscope canbe prevented from changing in the using process.

Description

technical field [0001] The invention relates to the field of endoscopes, and more specifically, to a transmission structure for an endoscope, an endoscope and a transmission method for precisely controlling a bending part of an endoscope. Background technique [0002] An endoscope is a comprehensive instrument that combines traditional optics, modern electronics, and mechanical structure software control. It is used to go deep into the tunnel and explore the internal environment of the tunnel. It is especially suitable for detecting the human body as a medical device, as well as other scenarios in the engineering industry that need to detect the internal environment of the tunnel. [0003] Considering that the working end of the endoscope goes deep into the tunnel, it is difficult to control it. Usually, the traction assembly is used to control the traction assembly through the endoscope set on the outer end of the tunnel or the control end on the outside of the tunnel, or c...

Problems solved by technology

[0004] In a control scheme for the endoscope, one end of the wire rope is connected to the working end of the endoscope, and the other end is connected to the control end of the endoscope, and the steel bar is tightened or loosened by the wheel to control the bending of the endoscope. The bending effect of the endoscope is controlled by this scheme. The shape of the bending part of the endoscope is uncontrollable. It is easy to cause abnormal parts in the bending part of the endoscope during the bending process due to the stretching of the steel bar on one side, which cannot be achieved. To adjust the orientation of the endoscope end as expected, it is necessary to provide an endoscope that can precisely control the bending shape
