Tissue Separation Device with Rotating Drum and Adjustable Blade
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for processing tissue samples into grafts often lack precision in producing a piece of tissue with a generally planar configuration and predetermined maximum thickness, especially when dealing with variable tissue types and densities.
Innovation Solution
A device comprising a rotatable drum assembly, blade assembly, and thickness adjustment mechanism, which allows for precise cutting and separation of tissue samples into planar pieces with controlled thickness, using a combination of rotational and lateral movement of the blade, and adjustable thickness settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional tissue processing methods are used, then tissue samples can be processed into grafts, but the precision in producing planar configuration and predetermined thickness is insufficient
Solution Approach 1:
The device is divided into distinct functional modules: a drum assembly for supporting and rotating the tissue sample, a blade assembly for cutting, and a thickness adjustment mechanism for controlling the cut depth. This segmentation allows each component to be optimized for its specific function while maintaining overall system precision.
Solution Approach 2:
The blade assembly is designed to move dynamically relative to the rotating drum, with the thickness adjustment mechanism enabling real-time modification of the cutting parameters. The drum rotation provides continuous motion while the blade reciprocates, creating a dynamic cutting process that ensures precise planar surfaces.
2Adaptability or versatility
If a fixed cutting mechanism is used, then the device structure is simple, but it cannot handle variable tissue types and densities with different thickness requirements
Solution Approach 1:
The thickness adjustment mechanism allows the blade position to be dynamically modified during operation, enabling the device to adapt to different tissue types and desired thicknesses. This dynamic adjustment capability provides versatility without requiring multiple specialized devices.
Solution Approach 2:
The device enables change of the cutting parameter (thickness) by adjusting the blade position relative to the drum surface. This parameter modification allows the same device to process various tissue types with different required thicknesses, maintaining versatility while controlling complexity.

AI summary
A device for separating a sample of tissue in a controlled and precise manner and, more particularly, to produce a piece of tissue having a generally planar configuration and, optionally, additional desired characteristics, such as a predetermined maximum thickness, and selected tissue type. The device is adjustable to allow for different thicknesses and different operational speeds for application to different types of recovered tissue samples.
