Solution Overview
Problem
Existing robotic catheterization systems lack a straightforward and reliable method for emergency removal of the catheter, which is essential for ensuring the safety of the surgeon and maintaining the system's maneuverability and reliability.
Innovation Solution
A driving module for robotic systems that includes a base with a mobile apparatus capable of rotating relative to the base, featuring a rotation driving system with access apertures allowing radial movement of the catheter, enabling easy uncoupling without compromising normal operation, and a removable cap that secures the catheter in place during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the catheter traverses closed passages in the robotic mechanism, then the system maintains sterility and reliability during normal operation, but emergency removal of the catheter becomes difficult or impossible
Solution Approach 1:
The mechanism is segmented into a closed passage system for normal operation and a separate access aperture system for emergency removal. The access aperture is positioned between rotation driving portions and allows the catheter to be radially moved outward from the receiving space to an external configuration, enabling quick removal while preserving the integrity of the closed passage system during standard use.
Solution Approach 2:
The access aperture acts as an intermediary structure that provides a dedicated emergency exit path for the catheter. This intermediary element allows the catheter to transition from the closed passage system to an external position without compromising the closed system's sterility and reliability during normal operation.
2Ease of operation
If access apertures are provided for catheter removal, then emergency removal becomes possible, but the system complexity increases
Solution Approach 1:
The access aperture functionality is extracted as a distinct structural element from the main closed passage system. By providing a separate radial access path between rotation driving portions, the emergency removal capability is added without requiring complex modifications to the existing closed passage mechanism, thereby minimizing overall system complexity.
3Loss of time
If the access aperture angle is increased to facilitate catheter removal, then emergency response time is reduced, but the structural design becomes more constrained
Solution Approach 1:
The access aperture is designed with a minimum angle of 30° that can be optimized to larger angles (45°, 90°, or more) depending on specific design requirements. This dynamic approach to aperture sizing allows the system to balance quick emergency removal with acceptable structural constraints, as the aperture geometry can be adjusted within a range of values rather than being fixed.
