Adjustable Locking Handle for Debrider Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical debridement devices often limit professionals to specific grip orientations, leading to suboptimal ergonomic positions and the need to alternate between multiple devices during procedures.
Innovation Solution
The development of an adjustable debrider device that allows for various grip configurations, including pen grip and pistol grip, through an adjustable and removable handle, enabling secure holding positions and ergonomic rotation of the nosecone.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed handle design is used, then the device structure is simple, but the ergonomic adaptability is limited
Solution Approach 1:
The handle is designed to be adjustable and removable, allowing it to be repositioned along the housing to different longitudinal locations. This dynamic configuration enables the same device to accommodate different grip orientations (pen grip, pistol grip, etc.) and hand sizes, resolving the contradiction between adaptability and structural simplicity
Solution Approach 2:
The handle is separated from the housing as an independent, removable component rather than being permanently integrated. This segmentation allows the handle to be detached and repositioned independently, providing ergonomic adaptability without permanently complicating the overall device structure
2Ease of operation
If a removable handle is used, then the ergonomic positioning is improved, but the device assembly complexity increases
Solution Approach 1:
The handle attachment mechanism allows for dynamic repositioning along the housing while maintaining secure connection. The mechanism enables easy adjustment to optimal ergonomic positions without requiring complex assembly or disassembly procedures, balancing operational ease with structural simplicity
Solution Approach 2:
The handle attachment mechanism is designed to accommodate multiple grip styles and hand sizes through a single universal interface. This multi-functional approach allows one mechanism to serve various ergonomic needs without requiring multiple specialized attachment systems

AI summary
A medical device for debridement can include a handpiece, a shaft extending through the handpiece and distally therefrom, a drive to manipulate the cutter, a handle slidably coupled to the elongate housing and extending distally therefrom, and at least one locking mechanism configured to fix the handle to the handpiece. The handle can be configurable to multiple positions along the length of the handpiece, and can be removed therefrom.
