Biopsy Device Removable Tray with Integrated Marker Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biopsy devices lack an efficient method for marking biopsy sites and managing tissue samples, particularly in terms of sample collection and marker deployment, which can be cumbersome and require multiple steps.
Innovation Solution
A biopsy device with a removable tray and integrated marker delivery system that allows for single-handed operation, enabling easy sample collection, visualization, and marker deployment without the need for additional tools or complex procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a biopsy device uses separate tools for sample collection and marker deployment, then each function can be optimized independently, but the procedural complexity increases and requires multiple steps
Solution Approach 1:
The patent combines the tissue sample collection function and marker deployment function into a single integrated biopsy device. The device includes a sample holder with a tray for collecting tissue samples and an integrated marker delivery system that can deploy markers at the biopsy site without requiring separate tools or procedures, thereby reducing procedural complexity while maintaining functional optimization
Solution Approach 2:
The biopsy device is designed with multi-functionality, serving both as a tissue sampling instrument and a marker deployment system. The single device performs multiple functions including tissue extraction, sample holding, and marker delivery, eliminating the need for multiple specialized tools and simplifying the overall procedure
2Measurement precision
If a biopsy device requires two-handed operation for sample management, then precise control can be achieved, but user convenience decreases and operation time increases
Solution Approach 1:
The device incorporates a spring-loaded ejection mechanism that automatically propels the tray outward when the button is pressed. This self-service mechanism eliminates the need for manual manipulation with both hands, allowing the user to simply press a button while the spring mechanism handles the tray ejection, thereby improving ease of operation while maintaining precise control through the button-actuated system
3Stability of the object's composition
If a biopsy device uses a fixed tray for sample collection, then structural stability is maintained, but sample removal and marker deployment become cumbersome
Solution Approach 1:
The tray is designed with dynamic characteristics, being spring-loaded to remain stationary during the biopsy procedure for stability, but capable of being quickly ejected when needed. The spring mechanism allows the tray to transition from a stable, fixed position during sampling to an easily removable position for marker deployment, combining structural stability with operational flexibility

AI summary
A biopsy device comprises a body, a needle, a cutter, and a tissue sample holder. The tissue sample holder comprises an outer cup and a cap. A tray retains severed tissue samples from a biopsy procedure. In some versions, the tray is selectively detachable from the cap in a one-handed operation by the user. The tray may be ejected into a sample container, such as a formalin cup. The cap may include a threaded portion that is configured to engage a complementary threaded portion of a sample container to seal the sample container once the tissue samples have been transferred to the sample container from the tissue sample holder of the biopsy device. One or more ports may be provided in the cap to manage excess fluid within the outer cup of the tissue sample holder, and/or to provide integrated access for a marker delivery device.
