Abstract:
Laser puncture technologies are widely used in medicine, and it is important to control the execution of such a procedure. In this work, using tubular bones as an example, it is shown that the position of the laser fibre end face in the biomaterial can be effectively monitored using acoustic methods. Acoustic monitoring, being a reliable indicator of the processes occurring during perforation, makes it possible to determine the moments of the beginning and the end of perforation of the external wall of the bone, as well as the moment when the fibre end reaches the opposite external wall. It is important that these effects are weakly dependent on the laser radiation wavelength used and the methods of acoustic registration. The results obtained can be used to clarify the mechanism of action of laser radiation on biotissues and to improve laser medical technologies.
