Vascular Intervention Robot Segmented Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vascular intervention procedures require high precision and expose operators to radiation for extended periods, necessitating a system that can remotely control surgical tools and facilitate easy disinfection of components.
Innovation Solution
A semi-automatic vascular intervention robot with a detachable structure, featuring a catheter rotation unit, guide wire rotation and supply unit, transfer unit, and expanding and contracting unit, allowing for 4 degrees of freedom and easy attachment/detachment of components, integrated into a vascular intervention system with a frame for enhanced mobility and radiation protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a master-slave type system is used to remotely control surgical tools, then operator radiation exposure is reduced, but device complexity increases
Solution Approach 1:
The system is divided into a master apparatus (operator's side) and a slave apparatus (patient's side with catheter and guide wire), allowing the operator to control surgical tools remotely without direct radiation exposure while maintaining functional complexity management through modular architecture
2Ease of repair
If components are made detachable to facilitate easy disinfection and replacement, then ease of maintenance is improved, but device complexity increases
Solution Approach 1:
The slave apparatus is segmented into detachable components including the catheter, guide wire, and supporting structures, allowing individual parts to be easily removed for disinfection or replacement while maintaining overall system functionality through standardized connection interfaces

AI summary
A vascular intervention robot includes a catheter rotation unit for rotating a catheter on an axis parallel to a longitudinal direction of the catheter, a guide wire rotation and supply unit that is provided at one side of the catheter rotation unit and that is provided for transferring a guide wire in a longitudinal direction of the guide wire and for rotating the guide wire on an axis parallel to the longitudinal direction of the guide wire in a state in which the guide wire is inserted in the catheter, a transfer unit for transferring the catheter rotation unit and the guide wire rotation and supply unit in the longitudinal direction of the catheter, and an expanding and contracting unit that is provided at another side of the catheter rotation unit and that is expandable and contractible along the longitudinal direction of the catheter while supporting the catheter when the transfer unit transfers the catheter rotation unit and the guide wire rotation and supply unit in the longitudinal direction of the catheter.
