Medical Tool Holding Device with Resorbable Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical tool packaging fails to reliably prevent user contact with sharp-edged working ends, leading to potential injury and contamination risks, and often requires additional aids for safe handling during insertion into handles or drive units.
Innovation Solution
A sterile package with a holding device featuring resilient clamping arms and adjustable end stops, including a stop made of resorbable material, that securely positions and protects the tool's working end, allowing safe handling and insertion without direct user contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the medical tool is held firmly in a defined position in the package, then the tool is protected from contamination and damage, but the tool may contact the inner protective packaging when inserted into a handle and become contaminated
Solution Approach 1:
The patent introduces a holding device with a stop as an intermediary element between the tool and the user's hand. The stop extends beyond the tool's working end and provides a surface for the user to press against, enabling insertion without direct contact with the sharp working end. This mediator transfers the insertion force while maintaining the tool's protective positioning within the package.
Solution Approach 2:
The holding device is segmented into distinct functional components: holding means for securing the tool in a defined position, and a stop for preventing user contact with the working end. This segmentation allows the device to simultaneously provide firm positioning for contamination prevention and a separate interface for safe handling during insertion.
2Reliability
If additional aids or tools are used to insert the medical tool into handpieces or drive units, then user safety is improved, but device complexity increases
Solution Approach 1:
The patent merges the holding function and the safety protection function into a single integrated holding device. The holding means secure the tool while the stop simultaneously prevents user contact with the working end. This combination eliminates the need for separate protective caps or additional handling tools, reducing overall system complexity while maintaining safety.
Solution Approach 2:
The holding device serves multiple functions: it positions the tool in a defined orientation within the package, protects the working end from contamination, and provides a safe interface for user handling during insertion. This multi-functionality reduces the need for additional separate components, thereby reducing device complexity.
3Object-affected harmful factors
If the working end is protected from user contact, then injury risk is reduced, but handling becomes more difficult
Solution Approach 1:
The stop acts as a mediator that allows user interaction with the tool without direct contact with the sharp working end. The user presses against the stop, which is positioned beyond the working end, thereby transferring the insertion force safely while maintaining protection of the working end from user contact.
Solution Approach 2:
The stop extends in a direction beyond the working end of the tool, creating an additional dimensional interface for user interaction. This allows the user to apply force from the proximal end side rather than attempting to grasp or contact the distal working end, thereby maintaining protection while enabling handling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution minimizes the risk of user injury and tool contamination by ensuring the working end is only touched by the resorbable stop during coupling, providing safe and stable support for medical tools during transport and use, preventing cross-contamination and ensuring easy handling.
