Removable Collection Container for Tissue Harvesting Flow Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collection devices for tissue sampling require complex disassembly to remove tissue material, which disrupts the operation of the associated tissue removal device.
Innovation Solution
A collection device with a shaver-side and vacuum-side flow connection, where the collection container is removably held on a connection housing, allowing for easy separation and removal of the container, and a switching device to toggle between collection and suction modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the collection container is integrated into the tissue collection arrangement, then tissue material can be collected and retained, but the device becomes complex to disassemble for tissue removal
Solution Approach 1:
The collection device is divided into separate functional modules: a connection housing with flow connections, a removable collection container, and a tissue removal device. This segmentation allows the collection container to be easily detached from the connection housing for simple tissue removal without complex disassembly of the entire system.
Solution Approach 2:
The collection container is extracted as a separate, removable component from the tissue collection arrangement. It can be detached from the connection housing and removed entirely, allowing straightforward access to collected tissue material without disassembling the integrated tissue removal device or vacuum system.
2Ease of operation
If the collection container is disassembled to remove tissue material, then tissue can be accessed, but the tissue removal device cannot operate during this time
Solution Approach 1:
The collection container is extracted as an independent removable unit that can be detached from the connection housing. This allows the tissue removal device to continue operating while the collected tissue is accessed by simply removing the container, eliminating downtime and maintaining continuous productivity.
Solution Approach 2:
The system enables continuous operation by allowing the collection container to be removed and emptied without interrupting the tissue removal process. The shaver can continue cutting tissue while the collected material is accessed through the removable container, ensuring uninterrupted workflow.
3Adaptability or versatility
If a bypass path is added to allow independent fluid flow, then the shaver can operate in pure suction mode, but the device complexity increases
Solution Approach 1:
The bypass path is merged with the connection housing to form an integrated dual-path system. This allows the housing to accommodate both the collection container flow path and the bypass path, enabling flexible operational modes without requiring separate, complex external piping or additional components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables simple and convenient removal of retained tissue material without interrupting the operation of the tissue removal device, allowing for continuous tissue collection and processing.
Implementation Method 1
a vacuum-side flow connection (16) which can be fluidly connected to a vacuum device (20), and a connecting path (14) which can be formed between the shaver-side flow connection (6) and the vacuum-side flow connection (16). A fluid flow (F) can be formed via this connecting path (14) from the shaver-side flow connection (6) to the vacuum-side flow connection (16), in which the removed tissue material (G) is transported away from the tissue removal device (4).
