Biopsy Tissue Collection via Adhesive Carrier Medium
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for collecting tissue samples from biopsy needles are cumbersome, require skill, and risk damaging the samples, making it difficult to maintain their morphology and keep track of multiple small tissue samples.
Innovation Solution
A tissue collection device using a carrier medium, such as biopsy paper or other materials, that adheres to the tissue sample within the biopsy needle, allowing for gentle and controlled removal and storage of samples in indexed compartments to prevent mixing and deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of tissue samples by rotating the needle and pressing against biopsy paper is used, then the tissue samples can be collected, but the samples may be damaged and morphology may be lost
Solution Approach 1:
A carrier medium is introduced as an intermediary between the tissue sample and the biopsy paper. The carrier medium receives the tissue sample from the inner needle and transfers it to the biopsy paper, preventing direct contact and potential damage during the transfer process
Solution Approach 2:
The sample collection process is segmented into distinct steps: the tissue sample is first transferred to a carrier medium, then the carrier medium with the sample is transferred to indexed compartments, and finally to biopsy paper for processing. This segmentation allows each step to be optimized independently for sample protection
2Productivity
If multiple small tissue samples are collected using traditional methods, then the samples can be obtained, but it becomes difficult to keep track of and distinguish between them
Solution Approach 1:
The device divides the collection system into multiple indexed compartments, each capable of holding a separate tissue sample on its own carrier medium. This segmentation allows multiple samples to be collected and tracked simultaneously without confusion
Solution Approach 2:
The carrier medium or compartment indicators may use color coding or visual markers to distinguish between different samples and their locations, making it easy to track and identify each sample's position in the collection device
3Ease of operation
If the inner needle is withdrawn to expose the tissue compartment for sample removal, then access to the tissue sample is created, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The carrier medium is designed to automatically receive the tissue sample when the inner needle is withdrawn, eliminating the need for manual intervention to transfer the sample. The sample self-transfers onto the carrier medium through the exposed tissue compartment
Solution Approach 2:
The carrier medium is pre-positioned and prepared before the biopsy procedure begins, with the tissue compartment and transfer mechanism already in place. This preliminary preparation eliminates the need for complex manual manipulation during the actual sample collection
