Title:
DEVICE FOR IMPROVING LIGHT PENETRABILITY AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/032466
Kind Code:
A1
Abstract:
Provided are a device for improving light penetrability and a method therefor, which are applied to tissue of a human body for a biomedical photoelectric technology. When a laser light (110) penetrates into the tissue (310) in a human body for a biomedical photoelectric technology, an ultrasound wave (210) generated by means of a high-intensity focused ultrasound probe (200) is focused to form an acoustic vortex structure (220) located around an advancing path of the laser light (110) in the tissue (310), such that the laser light (110) passes through a central silent vortex action area of the acoustic vortex structure (220). By means of the acoustic vortex structure (220), the surrounding tissue (310) forms a virtual optical waveguide on the advancing path of the laser light (110), thereby increasing the luminous flux of the laser light (110) passing through the acoustic vortex structure (220), and improving the light penetrability of the laser light (110).
