Tissue Refining Canister with Aperture Separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liposuction techniques lack efficient methods for large-scale isolation and refinement of adipose tissue, leading to tissue trauma and increased procedural complexity due to the presence of unwanted components like oil, blood, and anesthetic solution, with existing devices requiring multiple steps and potentially exposing the tissue to air, which can reduce viability.
Innovation Solution
A tissue refining device with a canister body that includes a vacuum port, tissue harvesting port, and a separator element with apertures to separate adipose tissue from other fluids, allowing for efficient processing and minimization of tissue trauma within a sterile environment, using a fluid bath to cushion the tissue and facilitate separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional liposuction techniques are used to harvest adipose tissue, then the tissue can be collected, but the tissue is contaminated with unwanted components (oil, blood, anesthetic solution) requiring multiple processing steps
Solution Approach 1:
The patent combines the harvesting and refining functions into a single integrated canister system. The canister receives harvested tissue through one port and simultaneously separates fluids through internal separators, eliminating the need for separate collection and processing steps that characterize traditional methods.
Solution Approach 2:
The canister serves multiple functions: it collects harvested adipose tissue, separates unwanted fluids through internal separators, and prepares refined tissue for reimplantation all within a single device. This multi-functionality reduces the number of procedural steps compared to traditional sequential processes.
2Quantity of substance
If multiple processing steps are used to separate adipose tissue from unwanted components, then separation can be achieved, but tissue trauma increases and viability decreases
Solution Approach 1:
The canister incorporates internal separators that divide the chamber into distinct zones: a harvesting chamber for receiving tissue and a refining chamber for separation. This segmentation allows gentle gravity-based separation of fluids from adipose tissue without the need for aggressive mechanical processing that would traumatize the tissue.
Solution Approach 2:
The internal separators act as intermediaries between the harvesting and refining zones. They allow unwanted fluids to pass through while retaining adipose tissue, enabling separation without direct mechanical intervention on the tissue itself, thus preserving viability.
3Quantity of substance
If traditional collection methods are used, then adipose tissue can be harvested, but the procedure time increases due to multiple processing steps
Solution Approach 1:
By merging harvesting and refining operations into a single canister, the patent eliminates the time required to transfer tissue between separate collection and processing vessels. The simultaneous occurrence of both functions within one device streamlines the overall procedure.
Solution Approach 2:
The canister is pre-configured with internal separators and multiple ports before use. This preliminary preparation allows immediate separation and processing of harvested tissue without requiring setup or assembly during the procedure, reducing overall procedural time.
4Quantity of substance
If adipose tissue is exposed to air during processing, then separation can occur, but tissue viability is reduced
Solution Approach 1:
The canister design allows processing to occur in a controlled environment where unwanted fluids are separated and removed through dedicated evacuation ports. By continuously removing air and fluids during processing, the system minimizes air exposure time and maintains a more favorable environment for tissue viability.
