Robotic Catheter Sheath Actuation for Easier Mitral Valve Repair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing minimally invasive surgical instruments for mitral valve repair require high technical skill and prolonged learning curves due to manual operations, limiting their clinical application.
Innovation Solution
An actuation power apparatus and surgical assistance system that enables semi-automatic adjustment of a catheter system, incorporating an outer, middle, and inner sheath unit, driven by robotic arms and controlled by a control device, reducing the need for full manual surgeon operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation by surgeons is used for mitral valve repair instruments, then the surgical procedure can be performed with existing technology, but the operational difficulty is high and learning curves are prolonged
Solution Approach 1:
The patent replaces manual mechanical operation with an automated robotic system. The robotic device includes a robotic arm with an actuation power apparatus that can automatically adjust the posture and position of the catheter system, substituting the surgeon's manual dexterity requirements with automated control mechanisms.
Solution Approach 2:
The catheter system is designed with self-adjusting capabilities through the actuation power apparatus. The system can automatically adjust its own posture and position without requiring continuous manual manipulation, enabling the device to service itself during the surgical procedure.
2Loss of time
If semi-automatic control is implemented for the catheter system, then the learning curve for surgeons is shortened, but the device complexity increases
Solution Approach 1:
The control system is divided into semi-automatic segments where the robotic device handles complex positioning and adjustment tasks automatically, while the surgeon retains control for decision-making and final adjustments. This segmentation allows surgeons to learn progressively rather than mastering all aspects of manual manipulation.
Solution Approach 2:
The actuation power apparatus serves as an intermediary between the surgeon's commands and the catheter system. It translates simple surgeon inputs into complex coordinated movements, reducing the learning burden while maintaining surgical control.
