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

Embodiment 1

[0047] see figure 1 , a transmission structure for an endoscope, including two sets of traction components 1 , fixing parts 2 and snake bones 3 .

[0048] Two sets of traction assemblies 1 are provided. The front end of the traction assembly 1 is fixedly connected to the snake bone 3 at several connection positions. The connection positions of the two sets of traction assemblies 1 and the snake bones 3 are opposite. The two sides of the adjusting part are fixedly connected with the adjusting part on the inner side of the adjusting part. During the deformation process of the traction assembly 1 pulling the serpentine 3, the two groups of traction assemblies 1 respectively define snakes at two opposite positions in the serpentine 3. The deflection angle and deformation of the bone 3 cooperate with each other to drive the snake bone 3 to change the curvature; the fixing part 2 is arranged at the rear end of the traction assembly 1 and locks the two sets of traction assemblies 1 a...

Abstract

The invention provides a transmission structure for an endoscope, the endoscope, a transmission method and a transmission system. The transmission structure for the endoscope is characterized in thatthe transmission structure comprises a traction assembly, a fixing piece and a snake bone, wherein the front end of the traction assembly is fixedly connected with the snake bone at a plurality of connecting positions, the traction assembly is opposite to the connecting positions of the snake bone and drives the snake bone to change a bending degree in a matched mode, and the fixing piece is arranged at the rear end of the traction assembly and locks the traction assembly at a preset position. According to the transmission structure for the endoscope, a bending shape can be accurately controlled according to a transmission method.

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...
