Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-frequency treatment apparatuses for living tissue are limited in their ability to seamlessly perform marking, incision, and resection treatments due to the lack of a versatile electrode configuration that can efficiently transition between these procedures.
Innovation Solution
A high-frequency treatment apparatus with a movable electrode member that can be positioned forward or backward within a flexible sheath, allowing for both distal end and side treatment portions to be exposed or retracted as needed, enabling effective marking, incision, and resection treatments through a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single high-frequency accessory is used for marking, incision, and resection treatments, then device complexity is reduced, but the ability to perform all three treatments effectively is compromised
Solution Approach 1:
The high-frequency accessory integrates three distinct electrode configurations (marking electrode, incision electrode, and resection electrode) into a single device. The electrode selection mechanism allows the practitioner to switch between different electrode types depending on the treatment phase, enabling one accessory to perform all three treatments (marking, incision, and resection) that previously required separate accessories.
Solution Approach 2:
The electrode portion is divided into multiple functional segments: a marking electrode for creating markings, an incision electrode for cutting tissue, and a resection electrode for removing tissue. These segmented electrodes are selectively deployed based on treatment requirements, allowing each electrode to be optimized for its specific function while being part of a unified accessory.
2Reliability
If multiple high-frequency accessories are used for different treatments, then treatment effectiveness is improved, but ease of operation deteriorates due to frequent accessory changes
Solution Approach 1:
By incorporating multiple electrode types within a single accessory, the practitioner eliminates the need to change accessories between treatment phases. The electrode selection mechanism allows seamless switching between marking, incision, and resection electrodes without removing and replacing the entire accessory, thereby maintaining treatment effectiveness while significantly improving operational convenience.
Solution Approach 2:
The accessory includes a dynamic electrode selection mechanism that allows the practitioner to switch between different electrode configurations during the procedure. This dynamic adaptability enables the single accessory to respond to different treatment requirements in real-time, maintaining effectiveness across all treatment phases without the operational burden of accessory changes.
3Device complexity
If the electrode portion is fixed within the flexible sheath, then device simplicity is maintained, but adaptability for different treatment phases is reduced
Solution Approach 1:
The electrode portion is designed to be movable relative to the flexible sheath through a selection mechanism. This dynamic configuration allows the practitioner to deploy different electrodes (marking, incision, or resection) as needed while maintaining a relatively simple overall device structure. The electrode can be positioned in different states (retracted or extended) depending on the treatment phase.
Solution Approach 2:
Multiple electrodes are nested within the flexible sheath in a compact arrangement. The electrodes are stored within the sheath when not in use and can be selectively deployed outward when needed. This nested configuration maintains device simplicity while enabling adaptability for different treatment phases through selective electrode deployment.

AI summary
A high-frequency treatment apparatus includes an insertion portion, a covering portion provided in a distal end portion of the insertion portion, an electrode portion provided in the covering portion, through which high-frequency current is to flow, including a side treatment portion arranged along an outer surface of the covering portion and a distal end treatment portion formed of a distal end portion of the electrode portion, and configured to be moved between a forward position where the distal end treatment portion is protruded from the covering portion with respect to a forward and backward movement direction and a backward position where the distal end treatment portion is arranged within the covering portion with respect to the forward and backward movement direction, and an operation member inserted through the insertion portion and connected to the electrode portion wherein the electrode portion is configured to be moved by operating the operation member.
