Canister Separator for Liposuction Tissue Refinement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liposuction techniques lack efficient methods for large-scale isolation and refinement of harvested 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 being cumbersome and requiring multiple steps.
Innovation Solution
A tissue refining device with a canister body and separator element that separates adipose tissue from other fluids using a funnel-shaped separator with apertures, allowing fluids to drain while retaining fatty tissue, connected to a vacuum source and syringe for efficient processing and re-implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional liposuction techniques are used to harvest adipose tissue, then fat removal is achieved, but the harvested tissue contains unwanted components (oil, blood, anesthetic solution) that require complex processing
Solution Approach 1:
The canister is divided into two separate chambers: an upper chamber for receiving harvested tissue and a lower chamber for collecting unwanted fluids. The separator element with apertures creates distinct functional zones, allowing simultaneous separation of fat from fluids without requiring multiple processing steps or devices.
Solution Approach 2:
The separator element extracts and removes unwanted components (oil, blood, anesthetic solution) from the harvested adipose tissue by allowing these fluids to pass through its apertures into the lower chamber, while retaining the fatty tissue in the upper chamber.
2Quantity of substance
If multiple processing steps are used to separate adipose tissue from fluids, then separation is achieved, but tissue trauma increases and procedural time extends
Solution Approach 1:
The device combines harvesting, separation, and collection functions into a single integrated canister system. The separator element performs both filtration and separation simultaneously, eliminating the need for sequential processing steps and reducing overall procedural time.
Solution Approach 2:
The canister serves multiple functions: it acts as a harvesting container, a separation device, and a collection vessel for both purified adipose tissue and waste fluids. The separator element provides multi-functionality by simultaneously filtering fluids and retaining tissue.
3Productivity
If centrifugation is used to separate adipose tissue, then separation efficiency improves, but device complexity and procedural steps increase
Solution Approach 1:
The invention replaces complex mechanical centrifugation systems with a simple passive separator element that uses gravity and pressure differential to achieve separation. The apertured separator provides centrifugal-like separation efficiency without requiring centrifugal force or complex machinery.
4Quantity of substance
If extensive handling and processing of harvested tissue is performed, then purification is achieved, but tissue exposure to air increases reducing survival rates
Solution Approach 1:
The canister provides a closed, controlled environment that minimizes tissue exposure to air. The separator element allows fluid removal while maintaining the tissue within the protected upper chamber, reducing oxidative damage and improving graft survival.
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
The device simplifies the tissue refinement process, reduces tissue trauma, and maintains a sterile environment, improving the yield of usable adipose tissue while minimizing exposure to air and handling, thus enhancing the success of autologous adipose tissue transplantation.
