Multi-Positional Surgical Tool Grip for Secure Angle Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical tools often require precise usage at various angles and limited visibility, necessitating improved ergonomic grips that allow caregivers to securely hold them in multiple orientations during minimally invasive procedures.
Innovation Solution
A multi-positional grip with a grip housing featuring grasping depressions and a user interface, allowing caregivers to hold the surgical tool in multiple orientations, enhancing comfort and flexibility based on caregiver preferences and procedural needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional surgical tool grip is used, then the structure is simple, but the caregiver can only hold it in one orientation, reducing flexibility during procedures
Solution Approach 1:
The grip housing is segmented into multiple grasping depressions (first, second, and third depressions) positioned at different locations and orientations. Each depression accommodates different hand positions, allowing the caregiver to grasp the tool in multiple orientations (e.g., neutral, pronated, or supinated positions) while maintaining a unified grip structure.
2Ease of operation
If the grip housing includes multiple grasping depressions, then comfort and flexibility are improved, but the manufacturing complexity increases
Solution Approach 1:
Multiple grasping depressions are integrated into a single grip housing component rather than being separate parts. The first, second, and third grasping depressions are combined in one molded structure, providing multiple comfortable holding positions while simplifying assembly and manufacturing processes.
3Measurement precision
If the user interface is positioned in a specific location, then operational precision is improved, but the grip design becomes more complex
Solution Approach 1:
The user interface is positioned within the grip housing at a specific location that aligns with the first grasping depression, creating a localized control zone. This positioning allows the caregiver's thumb or fingers to easily access operational inputs while maintaining a secure grip, concentrating functionality in a specific area without complicating the overall design.

AI summary
A multi-positional grip for a surgical tool includes a grip housing extending along an axis between a first end and a second end. A bottom surface at least partially defines a first grasping depression and a second grasping depression spaced from the first grasping depression. A top surface is spaced from the bottom surface by a pair of side surfaces. The top surface includes a user interface located proximate to the first end that includes at least one operational input. The grip housing is configured to provide a plurality of holding positions.
