Micro-Coring Needle Removal of Subdermal Fat With Minimal Tissue Disruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fat-removal procedures, such as liposuction, are disruptive to surrounding tissue and require skilled practitioners, posing risks and being time-consuming for removing small amounts of subcutaneous fat.
Innovation Solution
A method involving the use of a micro-coring needle to excise subdermal fat by insertion and removal, optionally accompanied by suction, liquid injection, and mobilization techniques like chemical, mechanical, or thermal modification to facilitate fat extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional liposuction is used to remove subcutaneous fat, then fat removal is achieved, but surrounding tissue is disrupted and complications increase
Solution Approach 1:
The patent divides the fat removal process into multiple small punctures rather than one large incision. Multiple fine needles create numerous small channels through which fat is extracted, segmenting the overall removal process into many minor interventions that collectively achieve significant fat reduction while preserving surrounding tissue integrity.
Solution Approach 2:
The invention extracts only the necessary subcutaneous fat through minimal punctures. By using fine needles that create small channels, the procedure removes targeted fat deposits without unnecessarily disrupting surrounding healthy tissue, achieving selective extraction that minimizes harmful effects.
2Quantity of substance
If conventional liposuction is used for small amounts of fat removal, then fat is removed, but the procedure becomes time-consuming and requires skilled practitioners
Solution Approach 1:
The patent employs multiple fine needles that can be inserted simultaneously or in rapid succession, allowing the procedure to proceed without requiring complex manual manipulation or highly skilled technical intervention for each individual fat removal site. The standardized needle design enables practitioners of varying skill levels to perform the procedure efficiently.
3Quantity of substance
If conventional liposuction is used, then fat removal is achieved, but the procedure is disruptive and poses risks such as excessive bleeding
Solution Approach 1:
The patent utilizes disposable fine needles that are discarded after single use. These disposable needles eliminate the risk of cross-contamination and reduce the complexity of sterilization procedures, thereby minimizing procedural risks and complications associated with reusable instruments.
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
Provides a simple and safe means to remove subcutaneous fat with minimal tissue disruption, reducing the need for skilled practitioners and minimizing complications.
Implementation Method 1
The above methods can further include the application of a suction force to the first and/or second needle while the tip is in contact with the subdermal fat. Here, the suction force results in subdermal fat being drawn into the needle. Alternatively, or additionally, a suction force is applied to the treatment area after the removal of the first and/or second needle. Here, the suction force results in subdermal fat being extruded from the treatment area.
Implementation Method 2
These methods can also, e.g., include injecting a liquid (e.g., saline solution) into the treatment area via the second needle at a pressure sufficient to force fat through the first needle.
Implementation Method 3
This mobilization can include, e.g., introduction of a chemical agent (e.g., a detergent) that denatures fat cells in the subdermal fat (e.g., through the first and/or second needle)
Implementation Method 4
This mobilization can include, e.g., introduction of a chemical agent (e.g., a detergent) that denatures fat cells in the subdermal fat (e.g., through the first and/or second needle), application of ultrasound, heating, cooling, or repeated cycles of heating or cooling of the subdermal fat
Implementation Method 5
This mobilization can include, e.g., introduction of a chemical agent (e.g., a detergent) that denatures fat cells in the subdermal fat (e.g., through the first and/or second needle), application of ultrasound, heating, cooling, or repeated cycles of heating or cooling of the subdermal fat
Implementation Method 6
This mobilization can include, e.g., introduction of a chemical agent (e.g., a detergent) that denatures fat cells in the subdermal fat (e.g., through the first and/or second needle), application of ultrasound, heating, cooling, or repeated cycles of heating or cooling of the subdermal fat
Data Source
AI summary
The present invention features methods of manipulating subdermal fat in a treatment area. Such methods include inserting a needle (e.g., a micro-coring needle) through the dermis to the subdermal fat layer in order to excise a portion of tissue from the treatment area. These insertions result in a portion of the dermis and a portion of the subdermal fat to enter into the needle. Removal of the needle results in excision of the portion of dermis and subdermal fat that entered into the needle.
