Rotating Biopsy Sample Holder with Instrument Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biopsy devices lack an efficient and user-friendly mechanism for obtaining and handling tissue samples, particularly in stereotactic and ultrasound-guided procedures, with existing systems often requiring complex setups and inadequate sample handling capabilities.
Innovation Solution
A biopsy system comprising a probe and holster with integrated sensors, a needle hub, cutter rotation and translation mechanism, and a tissue sample holder that allows for easy sample collection and handling, enabling efficient sample acquisition and storage without the need for extensive setup, and featuring a vacuum control module for fluid management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex setup is used for tissue sample acquisition, then the sample collection capability is improved, but the procedure complexity increases
Solution Approach 1:
The biopsy device is divided into modular components including a probe assembly, holster, tissue sample holder, and vacuum control module. Each component performs a specific function and can be independently assembled or disposed, reducing overall procedure complexity while maintaining reliable sample collection capability through coordinated operation of segmented functions.
2Reliability
If traditional tissue sample handling is used, then sample acquisition is achieved, but sample quality deteriorates due to inadequate handling
Solution Approach 1:
A dedicated tissue sample holder acts as an intermediary component between the biopsy probe and the operator. This holder provides a structured receptacle with proper orientation markings and secure positioning features that maintain sample quality during handling, while the vacuum control module serves as an intermediary for fluid management during the biopsy process.
3Ease of operation
If sharp components are handled traditionally, then disposal is possible, but safety and ease of disposal are reduced
Solution Approach 1:
The tissue sample holder and sharp component disposal are merged into a single integrated assembly. The holder structure incorporates secure receptacles that accommodate both tissue samples and sharp components together, allowing operators to dispose of both item types simultaneously in a single motion, thereby improving disposal ease while maintaining safety through the unified design.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system facilitates efficient and reliable tissue sample acquisition and handling, reducing the complexity of procedures and improving sample quality, while also enabling easy disposal of sharp components and providing a user-friendly interface for operators.

AI summary
A biopsy device includes a tissue sample holder (140) and a cutter defining a cutter lumen. In one example, the tissue sample holder has a manifold (144), a plurality of chambers (150) that are configured to separately hold tissue samples, and a cup (142) configured to cover the manifold and chambers. The tissue sample holder is rotatable to successively align the chambers with the cutter lumen. A longitudinal passage (158) extends along the manifold, and is positioned between two of the chambers. The manifold may be rotated to align the passage with the cutter lumen and with an opening (176) in the cup. The passage of the manifold and the opening in the cup are configured to permit a portion of an instrument (90) to be inserted through the opening and passage and into the cutter lumen. The instrument may be used to introduce one or more markers or medicine, etc., to a biopsy site.
