Cleanable Surgical Ratcheting Module with Fluid Access Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ratcheting mechanisms used in surgical instruments are difficult to clean due to their design, which often retains bodily debris within the inner mechanisms, and cannot be easily disassembled for thorough cleaning.
Innovation Solution
A cleanable ratcheting module with multiple cleaning fluid access ports and a unique selector blade mechanism that allows for easy disassembly and maintenance, enabling the flow of cleaning fluids through various channels to flush out debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional ratcheting mechanisms are used in surgical instruments, then the ratcheting function is achieved, but the mechanisms cannot be easily disassembled for cleaning and retain bodily debris
Solution Approach 1:
The ratcheting module is divided into separable components including a body, selector blade, and ratcheting mechanism. The selector blade can be detached from the body to provide access to internal channels for cleaning, allowing the mechanism to be disassembled for thorough cleaning while maintaining the ratcheting function when assembled.
2Reliability
If the ratcheting mechanism is sealed to protect internal components, then reliability is improved, but cleaning fluid cannot access internal mechanisms to flush out debris
Solution Approach 1:
Cleaning fluid access ports and internal channels serve as intermediaries that allow cleaning fluids to reach internal ratcheting mechanisms without compromising the sealed protective structure. The ports provide controlled access points where cleaning fluid can be introduced to flush debris from internal channels while the overall structure remains protected.
3Ease of operation
If multiple cleaning fluid access ports and channels are added, then cleanability is improved, but device complexity increases
Solution Approach 1:
The selector blade serves multiple functions: it selects ratcheting directions (clockwise, counter-clockwise, stationary) and simultaneously acts as a disassembly interface for cleaning. The same selector blade mechanism that controls ratcheting function also provides access to internal channels when detached, eliminating the need for separate cleaning access components.
4Reliability
If the selector blade mechanism is made secure to prevent accidental movement, then reliability is improved, but ease of disassembly for cleaning is reduced
Solution Approach 1:
The selector blade mechanism incorporates a spring-loaded detent system that provides secure positioning during normal operation but allows intentional disengagement. The spring-loaded nature provides sufficient holding force to maintain ratcheting position reliability while permitting deliberate removal by applying force to the selector blade for cleaning purposes.
