Biopsy Needle Position Overlay for Precise Puncture Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biopsy devices struggle to accurately compare the target position of a biopsy needle with its actual position, making it difficult to align and insert the needle correctly.
Innovation Solution
A biopsy device that displays a target image and an actual image of the biopsy needle in a common two-dimensional coordinate system, allowing for easy comparison and alignment, with features like overlapping images, operation reception regions, auxiliary lines, and additional images to guide the needle's path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a graphic indicating puncture path and puncture depth is displayed, then the puncture guidance is provided, but it is difficult to recognize the actual position relationship of the biopsy needle with respect to the graphic
Solution Approach 1:
The patent combines multiple images (target object image, biopsy needle image, and actual position image) into a single composite image displayed on one screen. This merging allows the operator to simultaneously view the target position, needle position, and their spatial relationships without switching between multiple displays, thereby improving both operational guidance and position recognition accuracy.
Solution Approach 2:
The patent introduces a composite image as an intermediary representation that integrates information from multiple sources (target object, biopsy needle, and their positional relationships). This composite image serves as a mediator between the actual physical setup and the operator's understanding, providing a unified visual reference that accurately reflects the spatial relationships without requiring direct observation of multiple separate elements.
2Illumination intensity
If multiple images are displayed separately, then each image can be clearly shown, but it is not easy to compare the target state with the actual state of the biopsy needle
Solution Approach 1:
The patent merges the target object image, biopsy needle image, and actual position image into a single composite image that preserves the clarity of individual elements while adding the capability to compare target state with actual state. The composite image maintains distinct visual representations of each component while establishing their spatial relationships, enabling both clear viewing and effective comparison simultaneously.
3Productivity
If the biopsy needle is moved freely toward the target object, then the procedure progresses efficiently, but there is a risk of unnecessary depth insertion
Solution Approach 1:
The patent implements a feedback mechanism where the composite image continuously displays the actual position of the biopsy needle relative to the target object during the procedure. This real-time visual feedback allows the operator to monitor insertion depth and adjust the needle position accordingly, preventing unnecessary deep insertion while maintaining procedural efficiency. The system provides ongoing information about the relationship between actual and target positions, enabling controlled advancement.
Data Source
AI summary
A controller includes a display controller that performs control to display a target image indicating a target object from which a tissue is to be collected by a biopsy needle, a first image indicating a target position of the biopsy needle, and a second image indicating an actual position of the biopsy needle in the same display diagram with a common two-dimensional coordinate system and to display the first image and the second image in different states.
