Robotic Drive Post Interface for Stable Catheter Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic medical procedure systems face challenges in stabilizing and maneuvering catheters and guidewires, particularly in tortuous or calcified vasculature, requiring longer guidewires and multiple operators for exchange, which complicates procedures like neurovascular and peripheral vascular interventions.
Innovation Solution
A robotic medical system with a vertical post and socket mechanism featuring tapered interfaces and cylindrical portions to securely attach and position the robotic drive, preventing rotation and facilitating stable attachment, thus allowing single-operator exchange and improved procedural efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional catheter exchange methods are used in tortuous vasculature, then guidewire support and navigation capability are improved, but procedure complexity increases requiring multiple operators and longer guidewires
Solution Approach 1:
The robotic drive acts as an intermediary device between the operator and the catheter/guidewire system. It provides stable distal support through automated positioning and manipulation, eliminating the need for multiple operators to manually support the guidewire during exchange procedures in tortuous vasculature
Solution Approach 2:
The patent replaces manual mechanical manipulation by multiple operators with an automated robotic system. The robotic drive uses motorized actuators and control systems to perform catheter exchange automatically, reducing procedure complexity while maintaining guidewire support
2Stability of the object's composition
If multiple operators are used for catheter exchange, then guidewire control and stability are improved, but procedural time and resource utilization worsen
Solution Approach 1:
The robotic drive performs catheter exchange operations autonomously without requiring multiple operators. The system self-manages guidewire stabilization, catheter manipulation, and exchange procedures through integrated sensors, actuators, and control algorithms, thereby improving procedural efficiency while maintaining stability
3Adaptability or versatility
If longer guidewires are used for distal support, then navigation capability in tortuous anatomy is improved, but device complexity and difficulty of manipulation increase
Solution Approach 1:
The robotic drive dynamically adjusts guidewire positioning and catheter manipulation based on real-time feedback from sensors and imaging systems. This dynamic control enables navigation through tortuous anatomy while maintaining ease of operation through automated adjustment, eliminating the need for manually managing long guidewires
