Biopsy Tissue Holder Assembly With Fluid Extraction for Clear Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluids present during the biopsy process interfere with the imaging of tissue samples, reducing the quality of images acquired by imaging devices such as X-ray imaging devices, which hinders effective diagnosis and increases the need for repeat procedures.
Innovation Solution
A tissue holder assembly with a rotatable tissue holder and a fluid removal mechanism, including a porous filter, fluid channel, and suction system to remove fluids from the imaging field, ensuring clear imaging of tissue samples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fluid is present during tissue sample transport, then the tissue sample can be delivered to the imaging system, but the fluid interferes with imaging quality
Solution Approach 1:
The patent extracts and removes fluid from the tissue sample container using a vacuum suction system before imaging. The fluid removal mechanism includes a vacuum source connected to the container to aspirate excess fluid, leaving only the tissue sample for clear imaging without fluid interference artifacts
Solution Approach 2:
The patent performs fluid removal as a preliminary action before the tissue sample is imaged. The system automatically aspirates fluid from the container after sample delivery but before the imaging sequence begins, ensuring the imaging field is clear of interfering fluids
2Measurement precision
If fluid is removed from the tissue sample, then imaging quality improves, but additional device components are required
Solution Approach 1:
The patent integrates multiple functions into the existing biopsy system. The vacuum system used for tissue sample aspiration is also used for fluid removal from the container. The imaging system includes both sample delivery and fluid removal capabilities, reducing the need for separate dedicated components
Solution Approach 2:
The patent combines the fluid removal mechanism with the existing vacuum system and imaging apparatus. The vacuum source serves dual purposes: aspirating tissue samples during biopsy and removing excess fluid from containers before imaging, thereby reducing overall system complexity

AI summary
A tissue holder assembly including a base having a bottom member, a central hub extending upwardly from the bottom member, and a circumferential sidewall extending upwardly from the bottom member radially spaced apart from the hub, the circumferential sidewall surrounding the hub and defining an interior region for accommodating a cylindrical tissue holder; the base further comprising a raised platform spaced upwardly apart from the bottom member, an upper portion of the central hub extending through a central opening of the platform, wherein the hub supports the tissue holder; the bottom member, the hub and the circumferential sidewall collectively defining an annular fluid channel underlying the platform, the fluid channel being in fluid communication with a platform opening and extending around the hub from the platform opening to a fluid exit port in the circumferential sidewall, to thereby provide unidirectional fluid flow around the hub of the base.
