Solution Overview

Problem

Conventional laser therapies for treating acute or chronic inflammation and wounds are limited by low power levels that prevent deep tissue penetration, leading to inadequate healing and potential tissue damage due to excessive heat, and require careful dosage to avoid radiation-related health issues.

Innovation Solution

A high-power laser irradiation system capable of generating optical energy at specific wavelengths and beam profiles that penetrate deep into tissues without ablating target or surrounding tissues, using wavelengths between 1064 nm and 1325 nm, with power levels up to 100 W, to stimulate cellular activity, promote healing, and reduce inflammation.

Solution Approach 1:

The patent changes the wavelength parameter of the laser to the infrared range (1064-1325 nm) where water absorption is minimized, allowing high power delivery without excessive heat generation in surrounding tissues. This parameter change enables deep tissue penetration while maintaining thermal safety.

Inventive Principle:

Solution Approach 2:

The patent converts the typically harmful thermal effect into a beneficial therapeutic effect by using controlled, moderate heat generation at high power levels to stimulate cellular metabolism and promote healing, while the specific wavelength selection prevents excessive heat that would cause damage.

Inventive Principle:

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

2Object-affected harmful factors

If conventional low power lasers are used to avoid tissue damage, then safety is improved, but deep tissue penetration capability deteriorates

Engineering Contradiction:

Improvetissue safetyVSAvoidpenetration depth

Core Design Contradiction:

Object-affected harmful factorsVSLength of moving object

Solution Approach 1:

The patent changes two key parameters simultaneously: increases power level from low to high, and shifts wavelength to the infrared range (1064-1325 nm). This combination allows the laser to penetrate deep into tissues while the water-transparent wavelength prevents excessive heat absorption that would cause damage.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The infrared wavelength range (1064-1325 nm) provides universal applicability for treating various tissue types and conditions at different depths, enabling the laser to function safely for both superficial and deep tissue treatments without requiring multiple laser systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Illumination intensity

If wavelengths that are strongly absorbed by tissue are used, then treatment intensity at the surface is improved, but penetration depth deteriorates

Engineering Contradiction:

Core Design Contradiction:

Illumination intensityVSLength of moving object

Solution Approach 1:

The patent selects specific infrared wavelengths (1064-1325 nm) where the absorption coefficient of water and tissue is minimized. This parameter selection creates an optimal balance where sufficient energy is delivered to reach deep tissues without being over-absorbed at the surface, enabling both adequate surface interaction and deep penetration.
