Detachable Rongeur Handle-Slider Lock for Thorough Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rongeurs, particularly laminectomy rongeurs, are difficult to clean thoroughly due to their non-detachable design, leading to potential cross-infection risks and time-consuming assembly/disassembly, and their spring fixation makes cleaning the fixing area challenging.
Innovation Solution
A detachable laminectomy rongeur with a movable handle and slider mechanism, featuring a trigger lock catch structure and torsion spring for easy assembly/disassembly, allowing thorough cleaning and reducing the risk of component loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rongeur is designed as a non-detachable structure, then the device maintains structural integrity and stability during operation, but it becomes difficult to thoroughly clean bone residues and tissue from gaps and fixing areas
Solution Approach 1:
The rongeur is divided into separable components including a handle, main body, and slider that can be detached from each other. The spring piece is also made as a separate component rather than being fixed to the main body. This segmentation allows each component to be cleaned independently, thoroughly removing bone residues and tissue from all surfaces and gaps while maintaining structural integrity during operation.
2Reliability
If the spring piece is fixed to the rongeur in a screwed manner, then the spring maintains stable positioning during use, but the fixing area becomes difficult to clean and sterilize
Solution Approach 1:
The spring piece is extracted from the fixed screwed manner and made into a separate, detachable component. It can be easily removed from the main body without screws or complex fastening mechanisms. This extraction eliminates the hard-to-clean fixing area while the spring maintains stable positioning during use through its designed engagement structure with the handle and main body.
3Ease of operation
If detachable rongeurs are designed to be disassembled into parts for cleaning, then thorough cleaning becomes possible, but assembly and disassembly time increases and component loss risk arises
Solution Approach 1:
The handle, main body, and slider are designed with complementary geometric features that enable intuitive alignment and automatic engagement during assembly. The spring piece has a dedicated placement position with shape-matched features. This merging design allows rapid reassembly of all components without requiring complex procedures or risk of losing parts, while still enabling thorough cleaning through complete disassembly when needed.
4Manufacturing precision
If the slider and main body require precise placement positioning for assembly, then proper functional alignment is achieved, but the assembly process becomes time-consuming and complex
Solution Approach 1:
The handle, main body, and slider incorporate asymmetric geometric features including protrusions, recesses, and shape-matched interfaces that provide intuitive alignment during assembly. These asymmetric features guide components into their correct positions automatically, achieving precise functional alignment without requiring complex positioning procedures or specialized tools, thereby simplifying the assembly process while maintaining high precision.
