Releasable Attachment Device for Surgical Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical device support systems are unable to adjust the position of medical devices during surgical procedures, as they are fixedly retained and lack the ability for releasable attachment.
Innovation Solution
A releasable attachment device with a fixed jaw and a moveable jaw, actuation mechanism, and tension component that allows for adjustable coupling to medical devices, enabling secure retention and easy release from support devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed retention mechanism is used to securely hold the medical device, then the device stability is improved, but the ability to adjust position is lost
Solution Approach 1:
The attachment device incorporates a movable jaw that can transition between fixed and adjustable positions, allowing the system to dynamically adapt between stable retention and position adjustment based on procedural needs
Solution Approach 2:
Different portions of the attachment device have specialized functions: the fixed jaw provides stable anchoring while the movable jaw enables position adjustment, allowing each local region to optimize its specific function
2Adaptability or versatility
If a fixed jaw and moveable jaw mechanism is implemented to enable adjustable coupling, then the position adjustability is improved, but the device complexity increases
Solution Approach 1:
The fixed jaw, movable jaw, actuation mechanism, and tension component are merged into a single integrated attachment device that couples to the medical device as one unified structure, reducing overall system complexity
3Ease of operation
If an actuation mechanism with locking structure is used to enable releasable attachment, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The tension component automatically urges the actuation mechanism toward the locked position and the movable jaw toward the closed position, reducing the need for complex control systems and manual intervention
