DEVICE AND METHOD FOR MATERIAL PROCESSING BY FOCUSED ELECTROMAGNETIC RADIATION Russian patent published in 2015 - IPC A61F9/01 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A device for material processing by focused electromagnetic radiation comprises: an electromagnetic radiation source; optical components directing and focusing the radiation on or to the material; a unit for a pattern generation in an electromagnetic radiation beam; a partially reflecting surface mounted on a beam path in front of the focus of the focused radiation to project the above pattern thereon by at least a portion of the above optical components; at least one detector configured to receive the pattern image reflected by the above surface and to generate electrical signals corresponding to the above image, which comprises a focus position data; a computer configured to receive the above electrical signals and programmed to process the above image and to generate the electrical signal dependent on the focal position. The computer is configured to determine the image sizes as a spread variation function during the generation of the above electrical signal. Besides, the device additionally comprises a spread control element mounted on the beam path and configured to receive the above electrical signal generated by the computer, and to change the electromagnetic radiation spread according to the above signal.

EFFECT: using the given group of inventions provides the fine adjustment of an incision depth.
