The development of a method for monitoring laser ablative exposure using spectroscopy in endoscopic operations

One of known problems of medical surgeries of laser ablation of tissues is no possibility of straight monitoring of field of ablation. Laser exposure can cause both excessive and insufficient effect what depends on laser settings (laser power, wavelength, size of field of illumination). Excessive ablation causes necrosis, carbonization of tissues and optical fiber may be burnt. Feedback between the value of exposure and performing degree of ablation must be fast for prevention of the unwanted damage during laser ablation. The article presents results of the research of the method of the real-time estimations of laser ablation on biological tissues for using during endoscopic surgery. According to results of preformed experiments were showed efficiency, workability and operation speed of the method.
