Solution Overview
Problem
Conventional medical snare devices are inconvenient and difficult to adjust, leading to inefficient polyp removal and excessive bleeding during procedures.
Innovation Solution
A medical snare device with a rotating body and guide holes for precise noose movement, combined with a chemical liquid supply system to inflate polyps, allowing easy insertion and minimization of bleeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the conventional snare configuration with twisting rotational force transmission is used, then the noose direction can be adjusted through manipulation, but the adjustment becomes inconvenient and difficult
Solution Approach 1:
Instead of rotating the noose to change direction, the patent inverts the approach by translating the noose linearly along the insertion tube to achieve directional adjustment. The distal end of the noose is pushed forward to rotate and change direction, eliminating the need for complex twisting mechanisms
Solution Approach 2:
The patent extracts the high-frequency current supply function from the manipulation mechanism. A separate high-frequency current supply unit is introduced that can supply current to the noose without requiring rotational force transmission, simplifying the manipulation mechanism while maintaining the ability to adjust noose direction
2Object-affected harmful factors
If separate hemostatic tool insertion is used to stop bleeding, then bleeding control is achieved, but the procedure time increases and patient discomfort increases
Solution Approach 1:
The patent merges the hemostatic function into the snare device itself by incorporating a high-frequency current supply unit that can be activated through the same insertion tube. This eliminates the need for separate hemostatic tool insertion, reducing procedure time and patient discomfort while maintaining effective bleeding control
Solution Approach 2:
The snare device is designed with multi-functionality, combining polyp resection and hemostasis capabilities in a single device. The high-frequency current supply unit enables the noose to perform both cutting and hemostatic functions, allowing the same device to address multiple clinical needs without requiring additional instrument insertions
