Medical Device Holder With Non-Parallel Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices, such as expandable baskets and retrieval devices, require complex hand manipulations or multiple users to extend and retract the end effector while coupled to an endoscope, making them difficult to use effectively.
Innovation Solution
The insertion device features a holder with a medical device receiving chamber and a deflection lever, allowing for easy coupling and decoupling of medical devices, enabling single-handed operation and efficient deployment of medical devices like expandable baskets through a semi-circular handle chamber and attachment surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If medical devices are coupled to endoscope working channels, then the medical devices can be delivered through the working channel to perform therapies or diagnostic evaluations, but extending and retracting the end effector requires difficult or complex hand manipulations or multiple users
Solution Approach 1:
A holder is introduced as an intermediary component that couples the medical device to the insertion device. The holder includes a receiving chamber that receives the handle of the medical device and positions it in a fixed relationship to the insertion device, eliminating the need for complex hand manipulations during extension and retraction operations.
Solution Approach 2:
The system is divided into separate functional components: the insertion device with delivery shaft, the holder as a coupling mechanism, and the medical device with handle and end effector. This segmentation allows each component to be optimized independently while working together as an integrated system.
2Productivity
If medical devices are coupled to endoscope working channels, then the medical devices can be delivered through the working channel, but the operation requires multiple users to hold separate components
Solution Approach 1:
The holder merges the insertion device and medical device into a single integrated assembly. By receiving the handle of the medical device in its receiving chamber and fixing it in position, the holder allows a single user to operate both components simultaneously without needing multiple users to hold separate parts.
3Ease of operation
If the holder includes a receiving chamber with non-parallel longitudinal axis, then the medical device can be securely positioned and operated with single hand, but the holder structure becomes more complex
Solution Approach 1:
The receiving chamber is designed with a non-parallel longitudinal axis relative to the insertion device, creating an asymmetric configuration that optimally positions the medical device handle for ergonomic operation. This asymmetric design allows single-handed operation while maintaining a relatively simple holder structure.

AI summary
An insertion device includes a body and a delivery shaft, and the body includes a longitudinal axis aligned with a central long axis of a proximal end of the delivery shaft. A holder may be coupled to the body of the insertion device, and the holder includes a medical device receiving chamber having a longitudinal axis that is non-parallel to the longitudinal axis of the body.
