Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing medical support devices and endoscope systems struggle to accurately display the presence position of in-body feature regions outside the image obtained by imaging the body's interior, especially when the positional relationship between the camera and the in-body feature region changes.

Innovation Solution

A medical support device equipped with a processor that acquires images from inside the body, generates screen information to display the image and presence position information of in-body feature regions recognized through object recognition, and adjusts the display position of this information based on changes in the positional relationship between the camera and the in-body feature region.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the display position of presence position information is fixed on the screen, then the device complexity is reduced, but the measurement precision of the in-body feature region position deteriorates when the camera moves

Engineering Contradiction:

Improvedisplay system complexityVSAvoidpresence position accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The display position of the presence position information is made dynamic rather than fixed. The information moves or adjusts its position on the screen based on the detected camera movement, ensuring that the displayed position accurately reflects the real-time location of the in-body feature region even as the camera moves during the procedure

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system detects camera movement and uses this feedback to adjust the display position of the presence position information. By continuously monitoring camera position changes and相应地 updating the display, the system maintains measurement precision without requiring complex hardware modifications

Inventive Principle:

Principle #23Feedback

2Ease of operation

If the presence position information is displayed outside the image frame, then the information is more visible to the user, but the loss of information about the feature region's relationship to the visible image increases

Engineering Contradiction:

Improvevisibility of position informationVSAvoidspatial relationship information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The presence position information acts as an intermediary element that bridges the visible image and the actual in-body feature region. By displaying this information outside the image frame with positional correlation, the system provides users with both the visual context and the precise location data without forcing overlapping displays that would reduce visibility

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A medical support device includes a processor. The processor acquires an image obtained by imaging an inside of a body with a camera. The processor outputs screen generation information used for generation of a screen on which the image and presence position information for specifying a presence position of an in-body feature region recognized by executing an object recognition process using the image on an outside of the image are displayed. A display position of the presence position information with respect to the image in the screen is changed according to a change in a positional relationship between the camera and the in-body feature region.
