Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatment systems for living tissues using ultrasound energy lack real-time monitoring and automatic shutdown mechanisms to prevent damage from end effector abnormalities, such as bending or falling off, which can lead to ineffective treatment and potential harm.
Innovation Solution
A treatment system that includes an imaging apparatus to capture images of the treatment area and a control device with a processor that acquires images, determines if an abnormality has occurred in the end effector, and automatically stops power supply to the treatment tool if an abnormality is detected, using shape recognition and threshold-based determination processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time image monitoring and automatic shutdown system are added to detect end effector abnormalities, then treatment safety and reliability are improved, but device complexity increases
Solution Approach 1:
An imaging apparatus is introduced as an intermediary component to capture images of the treatment area and transmit them to a control device. The control device then analyzes these images to detect end effector abnormalities, thereby indirectly monitoring treatment safety without requiring direct complex sensors in the end effector itself.
Solution Approach 2:
The system establishes a feedback loop where images of the treatment area are continuously captured, analyzed by the control device, and used to determine whether the end effector is functioning normally. When abnormalities are detected, the system automatically shuts down power supply, creating a closed-loop safety mechanism that continuously monitors and responds to treatment conditions.
2Measurement precision
If image capture and analysis functions are integrated into the treatment system, then abnormality detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The imaging apparatus serves multiple functions: it captures images for both treatment guidance and abnormality detection, and can be integrated with existing treatment systems. The control device performs dual roles of managing treatment parameters and analyzing images for safety monitoring, thereby reducing the need for separate dedicated components.
Solution Approach 2:
Instead of placing complex sensors directly in the end effector, the system creates visual copies (images) of the treatment area and analyzes these copies to detect abnormalities. This allows indirect observation of end effector conditions through image processing, avoiding the need for complex in-situ sensing components.
3Speed
If automatic shutdown mechanism is implemented based on image analysis, then response time to abnormalities is improved, but control system complexity increases
Solution Approach 1:
The control device is pre-programmed with abnormality detection algorithms and shutdown protocols. When images are captured, the system automatically compares them against known abnormal patterns and immediately executes pre-determined shutdown procedures, eliminating the need for complex real-time decision-making logic during actual treatment.
Solution Approach 2:
The system performs self-monitoring and self-protection by automatically analyzing images and shutting down power supply when abnormalities are detected, without requiring external intervention or complex manual control systems. The treatment system essentially monitors and protects itself through automated image-based detection.

AI summary
A treatment system includes a treatment tool, an imaging apparatus, and a control device. The treatment tool is configured to perform treatment on a living tissue by applying treatment energy from an end effector to the living tissue based on supplied electric power. The imaging apparatus captures an image of the living tissue in a state in which the treatment energy is applied from the end effector to the living tissue. The control device includes a processor to control the imaging apparatus by acquiring the captured image, determining whether an abnormality has occurred in the end effector based on the acquired captured image, and executing an instruction to stop supply of the electric power to the treatment tool when determining that the abnormality has occurred in the end effector.
