Solution Overview
Problem
Existing heating treatment apparatuses for living tissues face challenges in efficiently controlling temperature variations between holding members during treatment, which can affect the precision and effectiveness of procedures like sealing and incising tissues.
Innovation Solution
A heating treatment apparatus with a controller that switches between two modes: one where the first and second heat generating elements are set to equal temperatures, and another where they are set to different temperatures, allowing for optimal temperature control based on the treatment requirements, such as sealing or incising, by adjusting power supply and resistance detection circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holding members are heated to the same target temperature, then the temperature control is simplified and uniform, but it cannot adapt to different treatment requirements such as sealing and incising that require different temperatures
Solution Approach 1:
The patent implements dynamic temperature control by enabling the control unit to switch between different temperature control modes: a first mode where both holding members are heated to the same target temperature, and a second mode where the holding members are heated to different target temperatures. This dynamic adaptability allows the system to respond to different treatment requirements (sealing, incising, etc.) without increasing physical device complexity
Solution Approach 2:
The control unit changes the temperature parameter dynamically based on treatment needs. In the first temperature control mode, both holding members target the same temperature; in the second mode, they target different temperatures. This parameter change approach enables versatile temperature control while maintaining a relatively simple heating structure
2Productivity
If high temperature is applied for incising tissue, then the incising effectiveness is improved, but it may cause tissue carbonization and damage surrounding healthy tissue
Solution Approach 1:
The patent applies different temperatures to different holding members based on local treatment requirements. The first holding member can be heated to a higher temperature for effective incising, while the second holding member is heated to a lower temperature to prevent carbonization and protect surrounding healthy tissue. This localized temperature differentiation enables effective incising without excessive thermal damage
Solution Approach 2:
The control unit monitors treatment progress and tissue conditions, then adjusts the temperature of each holding member accordingly. During incising operations, the system can maintain higher temperature at the incising site while keeping adjacent areas at lower temperatures, providing feedback-based temperature regulation that prevents carbonization while maintaining incising effectiveness
3Object-affected harmful factors
If low temperature is used to prevent tissue carbonization, then tissue safety is improved, but the incising effectiveness and treatment efficiency are reduced
Solution Approach 1:
The patent implements local quality control by assigning different temperature levels to different holding members. The first holding member contacts the tissue at the incising site and is heated to a higher temperature for effective cutting, while the second holding member is heated to a lower temperature to prevent carbonization. This spatial temperature differentiation resolves the contradiction between incising effectiveness and carbonization prevention
Solution Approach 2:
The heating system is segmented into independent temperature control zones for each holding member. Each heat generating element can be controlled independently, allowing the first holding member to operate at higher temperature for incising while the second holding member operates at lower temperature to prevent carbonization, thus achieving both incising effectiveness and tissue safety
