High Frequency Treatment Tool Independent Wire Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of high-frequency treatment tools face hindrances in continuous operation due to the need to loosen and re-grip the operating wire after rotating the pipe, disrupting the simultaneous rotation and axial motion required for effective treatment.
Innovation Solution
A high-frequency treatment tool design featuring a flexible tube with a rotatable main body, a detachable power supply terminal, and a slider-fixing mechanism that allows the operating wire to slide and rotate independently, enabling continuous operation without the need to loosen and re-grip the wire during rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user rotates the entire pipe, then the treatment part can be repositioned, but the user must first loosen the gripping to move the operating wire back and forth, which interrupts continuous operation
Solution Approach 1:
The device is divided into functionally independent segments: the pipe rotation mechanism and the operating wire movement mechanism are separated. The operating wire can move back and forth within the pipe without being coupled to the pipe's rotation, allowing each function to be performed independently and continuously without interruption.
Solution Approach 2:
The operating wire is designed with dynamic movement capability, allowing it to slide freely back and forth within the pipe while the pipe itself rotates. This dynamic separation enables the wire to maintain its operational position and grip while the pipe repositions, eliminating the need to loosen and re-grip during rotation.
2Ease of operation
If the operating wire is fixed to the pipe, then rotation is simplified, but the wire cannot move back and forth independently to perform treatment functions
Solution Approach 1:
The device separates the wire movement function from the pipe rotation function by providing an independent sliding mechanism. The operating wire moves within the pipe through a dedicated guide structure rather than being rigidly attached, allowing independent motion while maintaining structural organization.
Solution Approach 2:
A guide structure or sliding mechanism acts as an intermediary between the operating wire and the pipe. This intermediary component enables the wire to move back and forth independently while the pipe rotates, providing a simple mechanical solution that adds minimal complexity.
3Productivity
If the user must loosen and re-grip the operating wire after rotation, then the wire can be repositioned, but operational efficiency and productivity are reduced
Solution Approach 1:
The operating wire maintains continuous movement capability throughout the rotation process. The wire can slide back and forth independently while the pipe rotates, ensuring that the useful action of wire movement never stops or requires interruption, thereby maintaining continuous treatment efficiency.
Solution Approach 2:
The wire is pre-positioned and secured in a manner that allows it to move freely during rotation without requiring subsequent adjustment. The initial positioning accommodates the full range of motion needed, eliminating the need for post-rotation re-gripping or repositioning.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates smooth and continuous rotation and sliding of the operating wire within the flexible tube, enhancing operational efficiency and reducing user effort, allowing for uninterrupted treatment procedures.
Implementation Method 1
a treatment part that is arranged on a distal end of the operating wire and is capable of treating biological tissue by applying a high-frequency current
Implementation Method 2
The slider-fixing part includes a locking part that is increased in diameter and deformed and engages with the slider-gripping part, rotatably couples the slider-gripping part to the slider-fixing part, and integrally couples the slider-gripping part and the slider-fixing part together in the axis direction of the main body

AI summary
A high-frequency treatment tool of the present invention includes a flexible tube that is inserted into a body cavity; an operating wire that is inserted through the flexible tube so as to be movable back and forth; a treatment part that is arranged on a distal end of the operating wire and treats biological tissue by applying a high-frequency current; a main body that fixes a base end of the flexible tube; a slider-fixing part that fixes a base end of the operating wire guided from the base end of the flexible tube and slides the operating wire in an axis direction with respect to the main body; and a slider-gripping part that is provided so as to encircle at least a portion of an outer peripheral surface of the slider-fixing part and slides the slider-fixing part by the operation of a user. The slider-fixing part is unrotatably coupled to the main body and the slider-gripping part is rotatably coupled to the slider-fixing part.
