AI Technical Summary

Technical Problem

The traction rope of existing endoscopes is prone to overflow and leakage before the adhesive solidifies, which leads to the failure of the traction function.

Method used

A traction wheel was designed with a rope passage and an adhesive holding structure. The adhesive holding structure provides a constrained space to accommodate the fixed section of the traction rope and the adhesive, ensuring that the adhesive does not overflow before and after solidification, thus achieving stable fixation of the traction rope.

Benefits of technology

Ensure the adhesive is fully mixed with the traction rope and secured to prevent spillage and leakage, thus ensuring the reliability of the endoscope's traction function and the flexibility of its use.

Abstract

This utility model discloses a traction wheel, an operating handle, and an endoscope, relating to the field of medical device technology. The traction wheel is suitable for connecting a traction rope, which transmits pulling force to achieve the bending action of the insertion part of the endoscope. It has a rope passage for the traction rope and a receptacle structure provided on the rope passage. The receptacle structure provides a confining space suitable for containing adhesive, and at least accommodates a fixed section of the traction rope so that the adhesive can fix the fixed section. The confining space can accommodate both the fixed section and the adhesive, which can be any liquid. After the adhesive solidifies, the fixed section is also fixed in the receptacle structure, achieving complete fixation of the traction rope. During solidification, the adhesive is constrained by the receptacle structure to prevent overflow or leakage, ensuring that sufficient adhesive can be fully mixed and fixed with the fixed section, thus securing the fixed section in the receptacle structure.
