Breast Biopsy Compression Member with Segmented Directional Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current breast biopsy techniques require the ultrasound probe and biopsy needle to be positioned far from the target, leading to suboptimal imaging and risk of needle contamination due to the need for an acoustic matching body.
Innovation Solution
A biopsy system with a compression member that allows insertion of both the biopsy needle and ultrasound probe, utilizing a processor for guiding the needle and probe positions to prevent contamination while maintaining high-quality ultrasound imaging, using an acoustic matching body in a non-contact state with the needle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the ultrasound probe is applied to a location close to the imaging target, then the ultrasound image quality is improved, but the biopsy needle may be contaminated by the acoustic matching body
Solution Approach 1:
The compression member is divided into a first compression portion and a second compression portion that can be independently adjusted. The first compression portion applies compression force in a first direction while the second compression portion applies compression force in a second direction, allowing separate optimization of probe positioning and needle insertion paths
Solution Approach 2:
The system introduces multi-directional compression capabilities by applying compression forces in different directions (first direction and second direction) through separate compression portions. This dimensional approach allows the probe to be positioned close to the target for high-quality imaging while the needle can be inserted from a different angular approach, avoiding contamination from the acoustic matching body
2Length of moving object
If the biopsy needle puncture position is close to the biopsy target part, then the invasive range of the biopsy needle is reduced, but the ultrasound probe must be positioned far from the target to avoid needle contamination
Solution Approach 1:
The compression member allows dynamic adjustment of compression forces in multiple directions during the biopsy procedure. The first and second compression portions can be independently controlled to adapt to different procedural stages, enabling close needle insertion while maintaining probe positioning flexibility
Solution Approach 2:
By introducing multi-directional compression capabilities, the system allows the needle and probe to operate in different spatial dimensions simultaneously. The needle can approach the target from one direction while the probe maintains optimal positioning from another direction, resolving the spatial conflict between minimizing needle invasion and maintaining probe proximity
3Reliability
If the ultrasound probe and biopsy needle are approached from separate locations, then the biopsy needle is protected from contamination, but the probe must be positioned far from the target resulting in lower image quality
Solution Approach 1:
The compression member is segmented into independent first and second compression portions that can be controlled separately. This segmentation allows the system to independently optimize the positioning of the ultrasound probe and the insertion path of the biopsy needle, enabling close probe positioning for high-quality imaging while maintaining separate approach paths to prevent contamination
Solution Approach 2:
The system changes the compression parameters (direction and magnitude) applied by different compression portions to optimize both probe positioning and needle insertion. By adjusting the compression forces in different directions, the system enables the probe to be positioned close to the target while the needle follows a contamination-free path

AI summary
A biopsy system performs a biopsy of a breast while capturing an ultrasound image with an ultrasonography apparatus, and includes: a compression member that has an opening portion into which a biopsy needle and an ultrasound probe used for capturing the ultrasound image are inserted and that compresses the breast; at least one processor that performs guide processing for guiding a target insertion position and a target insertion angle of the biopsy needle inserted into the breast and a target scanning position of the ultrasound probe; and an acoustic matching body that is provided between the ultrasound probe and the breast in a non-contact state with the biopsy needle.
