Solution Overview
Problem
Conventional endoscopic treatment instruments require operators to release and re-grasp the endoscope to rotate the distal end mechanism, leading to inconvenient handling and cable entanglement issues during high-frequency procedures.
Innovation Solution
An operation section structure with a sliding member and a conductive operating member that allows the main unit to rotate independently, enabling the distal end mechanism to rotate without rotating the operating member, while maintaining conductivity through a conductive section, and preventing cable entanglement with a freely rotating handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main unit is rotated to rotate the distal end mechanism, then the distal end mechanism can be repositioned, but the cable becomes entangled around the main unit
Solution Approach 1:
The instrument is divided into distinct functional segments: the main unit (with cable connection), the sliding member (conductive component), and the operating member (rotation control). This segmentation allows the main unit to rotate independently for repositioning while the operating member remains stationary, preventing cable entanglement. The sliding member acts as an intermediary that transmits conductivity without being constrained by cable routing.
Solution Approach 2:
The sliding member serves as an intermediary component between the main unit and the operating member. It maintains electrical conductivity while allowing the main unit to rotate without rotating the operating member. This intermediary structure enables the cable to remain stationary while still transmitting power to the rotating distal end mechanism.
2Ease of operation
If the operator releases and re-grasps the endoscope to rotate the distal end mechanism, then the distal end mechanism can be rotated, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The system provides dynamic rotation capability where the main unit can be rotated freely while the operating member remains stationary. This dynamic design allows the operator to reposition the distal end mechanism without releasing the grip on the operating member, eliminating the need for repeated grasping and releasing actions.
Solution Approach 2:
The rotation function and the conductivity function are merged into a single integrated structure. The main unit combines both the cable connection (for power supply) and the rotation capability in one component, allowing the operator to control both functions simultaneously without separate manipulation steps.
3Ease of operation
If the operating member is made rotatable relative to the sliding member, then the distal end mechanism can rotate easily, but the conductivity may be compromised
Solution Approach 1:
The rotating and non-rotating components are segmented into distinct parts: the main unit (with cable connection) and the operating member. The sliding member is positioned between them to maintain electrical contact. This segmentation allows the main unit to rotate while the operating member remains stationary, preserving conductivity through the sliding member interface.
Solution Approach 2:
The sliding member acts as an intermediary that maintains electrical conductivity while allowing rotational movement. It provides a stable conductive path between the main unit and the operating member, ensuring that rotation does not compromise the electrical connection required for high-frequency power supply.

AI summary
An operation section structure of a treatment instrument for endoscopic use has: a hook knife inserted into a body cavity; a wire having a distal end connected to the hook knife; a tubular flexible sheath provided to an outer periphery of the wire; a current-carrying plug having a main unit having a distal end connected to the sheath; a sliding member made of a conductive material and having a proximal end of the wire fixed thereto, the sliding member being capable of sliding on the main unit in longitudinal direction; a operation member capable of freely rotating in circumferential direction of the operation member; and attached to the sliding member; and a conductive section provided to the operation member, the conductive section being made of a conductive material providing conductivity by making contact with the sliding member. This configuration can rotate the distal end structure easily.
