Solution Overview

Problem

Existing methods for treating cellulite, such as cutting septa, require significant force and can result in undesirable contact with other tissues, posing challenges in effectively addressing the dimpled appearance of the skin.

Innovation Solution

An ultrasonic probe that transmits energy along a shaft with a notch at the distal end, allowing for the severing of fibrous tissue without requiring excessive force, and is designed to fragment or emulsify adipose tissue, reducing tissue contact surface area and enhancing cutting efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a cutting instrument is used to physically cut through the fibrous tissue of the septa, then the septa can be severed to allow skin to move with fat cells, but significant force must be applied by the surgeon which can thrust the cutting instrument forward or sideways into the patient, potentially resulting in undesirable contact with other tissues

Engineering Contradiction:
Improveforce applied by surgeonVSAvoidundesirable contact with other tissues
Core Design Contradiction:
ForceVSObject-affected harmful factors

Solution Approach 1:

The patent replaces manual mechanical cutting with ultrasonic vibration-based cutting. The ultrasonic probe generates high-frequency vibrations that sever the septa through vibrational energy rather than direct mechanical force applied by the surgeon's hand, eliminating the thrusting problem while maintaining effective tissue separation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the cutting mechanism from static mechanical force to dynamic ultrasonic vibration. By transforming the cutting action into high-frequency oscillations, the system achieves effective tissue severing with minimal applied force, preventing instrument displacement and unwanted tissue contact.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If a cutting instrument is used to sever the septa, then the dimpling on the outer surface of the skin can be reduced, but the surgeon must apply enough force to physically cut through the fibrous tissue which creates risk of instrument thrusting

Engineering Contradiction:
Improveeffectiveness of septa severingVSAvoidease of controlling cutting instrument
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The ultrasonic probe replaces manual cutting instruments, converting the cutting action into controlled ultrasonic vibrations. This substitution maintains reliable septa severing while dramatically improving ease of operation, as the surgeon simply guides the probe without needing to apply significant cutting force.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The ultrasonic probe performs the cutting action through its own vibrational energy rather than relying on the surgeon's mechanical force. The instrument essentially cuts itself through ultrasonic oscillations, making the procedure easier to control while maintaining effective tissue severing.

Inventive Principle:
Principle #25Self-service

3Productivity

If traditional mechanical cutting is used to treat cellulite, then the septa can be cut to allow skin movement, but the process requires significant surgical force and carries risk of tissue damage

Engineering Contradiction:
Improveefficiency of cellulite treatmentVSAvoidrisk of tissue damage
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional mechanical cutting with ultrasonic vibration-based tissue severing. This substitution maintains high productivity in treating cellulite by efficiently separating septa while reducing the risk of tissue damage through controlled vibrational energy rather than blunt mechanical force.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent converts potentially harmful mechanical thrusting forces into beneficial controlled ultrasonic vibrations. The energy that could cause unwanted instrument movement and tissue damage is transformed into precise, localized vibrational cutting that severs septa effectively while minimizing harm to surrounding tissues.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

An ultrasonic probe transmits ultrasonic energy along a shaft from a proximate end to a distal end. The ultrasonic probe includes at least one notch on its distal end. Fibrous tissue, such as septa that connect skin layers to muscle layers of animal tissue, can be positioned within the notch so that it is in contact with at least a portion of the distal end of the ultrasonic probe. The ultrasonic energy conducted through the ultrasonic probe to the distal end will sever the fibrous tissue in the notch. The ultrasonic probe is also designed, in embodiments, to fragment or emulsify adipose tissue, as part of an ultrasonic assisted lipoplasty (UAL) procedure.
