Solution Overview
Problem
Existing tissue collection devices are cumbersome, bulky, and inefficient for rapid collection of multiple tissue samples, making them difficult to handle and examine, especially for preliminary X-ray analysis.
Innovation Solution
A compact tissue collection device with a swiping element that moves sideward through the biopsy needle's tissue compartment to deposit tissue samples onto a carrier medium, allowing for simple and repeatable operation, and a removable carrier medium cassette for easy handling and storage of samples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a rotatable drum with tissue storage chambers is used to collect tissue samples, then tissue samples can be collected and stored, but the device becomes bulky and difficult to handle for preliminary examination
Solution Approach 1:
The device divides the tissue collection system into separate functional components: a biopsy needle for sample acquisition, a carrier medium for sample deposition, and a compact housing. This segmentation eliminates the need for a large rotatable drum while maintaining sample collection capability through a linear carrier medium that moves through defined positions.
Solution Approach 2:
The invention transitions from a three-dimensional rotatable drum structure to a more compact arrangement where the carrier medium moves linearly through collection and deposition positions. This dimensional reorganization reduces the overall device volume while preserving the essential function of collecting and storing multiple tissue samples.
2Ease of operation
If a lever with a cassette is used to displace and collect tissue samples, then samples can be removed from the biopsy needle, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The carrier medium is pre-positioned with a reception position aligned with the biopsy needle's tissue compartment before sample collection begins. This preliminary positioning eliminates the need for complex lever operations and cassette adjustments during the collection process, enabling rapid and straightforward sample deposition.
Solution Approach 2:
The carrier medium automatically advances through the collection and deposition positions after each sample is deposited, eliminating the need for manual lever operations. The system performs the sample collection and transport functions automatically, reducing both operational complexity and time requirements.
3Device complexity
If the deposition position is the same as the collection position, then the device structure is simplified, but tissue samples cannot be properly separated and stored
Solution Approach 1:
The device clearly separates the collection position and deposition position as distinct functional zones along the carrier medium's path. This spatial segmentation ensures that samples are deposited at a different location than where they are collected, enabling proper sample separation and storage while maintaining a relatively simple linear device structure.
4Quantity of substance
If a bulky biopsy gun with integrated tissue collection device is used, then tissue samples can be collected and stored, but the device is difficult to handle and examine
Solution Approach 1:
The invention extracts the tissue collection and storage function from a bulky integrated biopsy gun, creating a separate compact tissue collection device. This extracted design maintains adequate sample storage capacity through the carrier medium system while dramatically improving device handling and examination ease through its compact, streamlined structure.

AI summary
A tissue collection device including a biopsy needle support arrangement to support a biopsy needle so that a tissue compartment in the biopsy needle may be located at a collection position. The tissue collection device includes a carrier medium adapted to adhere to and carry a tissue sample deposited thereon and adapted to be arranged at a deposition position permanently spaced from the collection position. The tissue collection device includes a swiping element adapted to swipe sideward relative to the longitudinal direction through the tissue compartment located at the collection position and in the direction of the deposition position in order to thereby move a tissue sample from the tissue compartment to the carrier medium and to thereby press the tissue sample onto the carrier medium so that the tissue sample is deposited on the carrier medium.
