Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical equipment systems for surgical instrument replacement lack efficiency in returning instruments to a predetermined origin position, leading to potential tissue damage and increased operational complexity.
Innovation Solution
A medical equipment system featuring a detachable interface with an origin return mechanism, including a moving member, return member, and biasing member, which automatically returns the surgical instrument to a predetermined origin position when detached, utilizing a rotary member and cam system for precise positioning and a wireless tag for instrument identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a detachable interface is used for surgical instrument replacement, then the replacement process is simplified and work efficiency is improved, but the surgical instrument may not return to a predetermined origin position automatically, increasing the risk of tissue damage
Solution Approach 1:
The origin return mechanism is pre-configured in the detachable interface to automatically return the surgical instrument to a predetermined origin position when detachment occurs. This preliminary action ensures safety is built into the replacement process itself, eliminating the need for manual position verification while maintaining high work efficiency.
2Device complexity
If manual return to origin position is required, then the structure can be simpler, but the replacement process becomes more complex and time-consuming
Solution Approach 1:
The origin return mechanism enables the detachable interface to automatically perform the return-to-origin function without requiring manual intervention. The mechanism self-activates upon detachment, eliminating additional operational steps and reducing replacement time while maintaining relatively simple structure through integrated design.
3Manufacturing precision
If an origin return mechanism is added, then the safety and precision of instrument positioning is improved, but the device complexity increases
Solution Approach 1:
The origin return mechanism is merged with the detachable interface structure, combining the positioning function with the existing connection mechanism. This integration achieves precise positioning without adding separate complex subsystems, as the return function is embedded within the interface itself through coordinated movement of coupling components.
4Device complexity
If the surgical instrument is not returned to origin position, then the mechanism can be simpler, but tissue damage may occur due to improper positioning
Solution Approach 1:
The origin return mechanism proactively prevents the harmful effect of improper positioning by automatically returning the surgical instrument to the correct origin position. This preliminary anti-action counteracts the potential harm before it can occur, eliminating tissue damage risk without requiring complex additional control systems.
