Remote Multi-Chamber Tissue Sample Holder for Single-Handed Biopsy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biopsy devices lack efficient mechanisms for collecting, transporting, and analyzing tissue samples in a single, integrated system, particularly under stereotactic guidance, without requiring complex tethering or multiple hand operations.
Innovation Solution
A biopsy device with a probe and holster system that allows single-handed operation, incorporating a tissue handling assembly with a transport tube and sample holder, featuring a mechanical tissue manipulation assembly to compress and guide samples, and a real-time analysis system for preliminary assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a biopsy device uses multiple separate components for collection, transport, and analysis of tissue samples, then each component can be optimized for its specific function, but the overall device complexity increases and requires multiple hand operations
Solution Approach 1:
The patent combines multiple separate biopsy functions (collection, transport, and analysis) into a single integrated device. The collection needle, transport mechanism, and analysis chamber are merged into one unit that can be operated with a single hand, eliminating the need for multiple separate components and hand operations.
Solution Approach 2:
The biopsy device is designed as a multi-functional tool that performs collection, transport, and preliminary analysis of tissue samples within a single device. This universal design allows one device to replace multiple specialized tools, improving ease of operation while maintaining functional optimization through integrated design.
2Ease of operation
If a biopsy device requires tethering to vacuum modules and control modules for fluid communication and power, then reliable fluid transport and control are achieved, but the ease of operation decreases and setup complexity increases
Solution Approach 1:
The patent extracts the vacuum and control modules from external tethered systems and integrates them directly into the biopsy device housing. This allows the device to operate without external tethers while maintaining reliable fluid transport and control functions through built-in vacuum chambers and control mechanisms.
Solution Approach 2:
The biopsy device incorporates self-contained vacuum generation and fluid control capabilities within its own housing. The device serves its own fluid transport and control needs through integrated pumps and valves, eliminating dependence on external tethered systems while maintaining operational reliability.
3Productivity
If tissue samples are collected and transported without immediate analysis capability, then the collection process is simplified, but diagnostic feedback time increases
Solution Approach 1:
The patent merges the tissue sample collection function with an integrated analysis chamber that can immediately process and evaluate collected samples. The analysis chamber is positioned within the device housing, allowing continuous real-time analysis as samples are collected and transported, thereby reducing diagnostic feedback time without requiring separate analysis equipment.

AI summary
A biopsy system includes a biopsy device, a control module, and a tissue transport tube. The biopsy device includes a probe, a needle, a cutter, and a transport valve. The needle extends distally from the probe. The cutter is movable relative to the needle and defines a cutter lumen. The holster is configured to couple to the probe. The transport valve is in communication with the cutter lumen. The control module is in communication with the biopsy device and includes a sample management assembly configured to receive one or more tissue samples severed by the cutter. The transport tube extends between the sample management assembly and the biopsy device. The transport tube is in communication with the transport valve such that the transport tube is configured to receive the one or more tissue samples severed by the cutter.
