A Device for Laser Fiber Perforations of Biomaterials

Abstract

Abstract—A device has been designed for perforation of biological materials using fiber lasers. Perforations are carried out under various parameters of laser impacts (continuous and pulsed radiation, wavelength, power) and a given pressing force of the optical fiber to the surface of the biological tissue. High-speed video recording and acoustic measurements are used to record fast processes. When perforating the fabric, the temperature of the fiber end-face heating, its position and movement speed are controlled. The system is designed to improve laser puncture technologies and to select the optimal parameters for laser exposure and development of new medical robotics.
