Detachable Endoscope Rack Gear Coupling for Stable Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detachable endoscopes face issues with unstable operation of operating wires, leading to unreliable performance during endoscopic surgery, as the connection between the insertion and operation units results in incorrect quantitative linear motion.
Innovation Solution
A detachable endoscope design featuring a detachable unit with first and second modules, utilizing rack gears and pinion gears to ensure precise and stable vertical and horizontal bending of the insertion unit's front end, allowing for easy replacement and disinfection of the insertion unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the operation unit and insertion unit are detachably coupled by a connection unit, then the insertion unit can be replaced for storage or disinfection, but the operating wires perform incorrect quantitative linear motion and operate unstably
Solution Approach 1:
The endoscope is divided into separable operation unit and insertion unit through a connection unit, allowing the insertion unit to be detached for storage or disinfection while maintaining the operational integrity of the operating wires through structured connection mechanisms
2Ease of repair
If the operation unit and insertion unit are detachably coupled by a connection unit, then the insertion unit can be replaced for storage or disinfection, but the front end operation precision deteriorates
Solution Approach 1:
A connection unit acts as an intermediary between the operation unit and insertion unit, providing a structured interface that maintains the precision transmission of operating wires while enabling detachable coupling for maintenance and disinfection
