Image-Based Incision Completion Detection for Treatment Instruments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing treatment systems rely on visual confirmation by operators to determine the completion of tissue incision, leading to potential time lags and unnecessary power supply to treatment instruments.
Innovation Solution
A treatment system with an imaging device and control device that calculates a temporal change amount of the treatment instrument relative to a predetermined point or area in the captured image to determine incision completion and automatically stop power supply to the instrument.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If visual confirmation by operator is used to determine incision completion, then the system is simple to operate, but the response time is delayed and unnecessary power supply occurs
Solution Approach 1:
The patent replaces the manual visual confirmation method with an automated image processing system. The control device automatically analyzes captured images to detect incision completion by calculating temporal change amounts of the treatment instrument's position and shape, eliminating the need for operator visual monitoring and reducing response time delays
Solution Approach 2:
The system enables self-service operation where the control device autonomously determines incision completion without requiring continuous operator intervention. The automated detection system processes images and controls power supply independently, allowing the system to serve itself in monitoring and decision-making functions
2Productivity
If continuous power supply to treatment instrument is maintained during operator visual monitoring, then the treatment can proceed without interruption, but unnecessary power consumption and load occur after incision completion
Solution Approach 1:
The patent implements a feedback mechanism where the control device continuously monitors captured images during treatment, calculates temporal changes in the treatment instrument's position and shape, and uses this feedback information to automatically determine when incision completion has occurred, thereby controlling power supply accordingly
Solution Approach 2:
The system employs periodic image capture and analysis during the treatment process. The control device acquires captured images at regular intervals, processes them to detect incision completion, and controls power supply based on these periodic assessments, ensuring treatment continuity while avoiding unnecessary post-completion power consumption

AI summary
A treatment system that includes a treatment instrument to apply a treatment energy to a living tissue from an end effector according to a supplied electric power to incise the living tissue, an imaging device to generate a captured image capturing a state in which the treatment energy is applied from the end effector to the living tissue, and a control device that includes a processor to control operation of the imaging device. The processor acquires the captured image, calculates a temporal change amount based on any one of a predetermined point and a predetermined area in the captured image as a determination value, determines whether incision of the living tissue has been completed based on the determination value, and in response to determining that incision of the living tissue has been completed, execute an instruction to stop supply of the electric power to the treatment instrument.
