Medical Device Selection Controller for Lesion Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Selecting the optimal atherectomy device or treatment method for individual patients is challenging due to varying symptoms, relying heavily on physician experience rather than objective criteria.
Innovation Solution
A medical system with a display and controller that acquires and ranks different types of medical devices and treatment methods based on their features and the characteristics of the target lesion, reducing the operator's burden by providing a list of suitable options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the operator selects devices based on personal experience, then the selection process is simple and quick, but the accuracy and objectivity of device selection deteriorates
Solution Approach 1:
The patent replaces the mechanical decision-making process (physician's personal experience and judgment) with an automated information processing system. The controller automatically acquires device information, target object information, ranks suitable devices, and displays results, eliminating the need for operators to manually evaluate multiple devices based on subjective experience.
Solution Approach 2:
The system performs self-service by automatically determining the most suitable devices without requiring extensive operator intervention. The controller independently acquires and processes information, performs ranking calculations, and presents recommendations, allowing the system to serve itself rather than relying on operator expertise for each decision.
2Loss of time
If the operator manually evaluates multiple devices, then the selection can be customized, but the time required for selection increases
Solution Approach 1:
The system performs preliminary actions by pre-acquiring and storing device information and treatment method information in advance. When a treatment is needed, the controller simply retrieves pre-processed information, ranks devices based on stored criteria, and displays results immediately, eliminating the need for real-time manual evaluation of multiple devices.
Solution Approach 2:
The manual evaluation process is replaced with automated information processing. The controller automatically acquires device information, compares it with target object characteristics, performs ranking calculations, and presents results, significantly reducing selection time while maintaining ease of operation through automated decision support.
3Reliability
If the operator uses personal experience for selection, then the process requires minimal training, but the consistency and reliability of selection deteriorates
Solution Approach 1:
The patent replaces subjective human judgment with objective automated processing. The controller uses programmed criteria to automatically evaluate device information against target object characteristics, ensuring consistent and reliable selections that do not vary based on individual operator experience or bias.
Solution Approach 2:
The system transforms qualitative selection criteria into quantifiable parameters. By converting device features and treatment requirements into measurable data points that can be automatically compared and ranked, the system achieves consistent reliability while managing complexity through structured parameter-based evaluation rather than subjective judgment.

AI summary
A medical system for removing an object in a body cavity, includes a display, and a controller connectable to a drive device configured to control a medical device operated by an operator to remove the object. The controller is configured to acquire device information indicating features of different types of first devices connectable to the medical device, acquire target information indicating characteristics of a target object to be removed, rank the first devices for removing the target object using the device information and the target information, and display on the display a list of the first devices according to the rank thereof.
