A system for treatment of wounds consists of a treatment housing, a fluid delivery mechanism for supplying debridement fluids to the wound treatment area, an evacuation mechanism for evacuation of debris from the treatment chamber. A handheld device is connected to the treatment housing, wherein its interior accommodates a laser source, a scanning device, an image recording device and at least one sensor/detector, a control unit having a microprocessor for controlling operation of the system. The sensor detects concentration of various substances in the wound, and the microprocessor analyzes data obtained by the sensor and generates signals to adjust parameters of the laser, the liquid dispensing nozzles and the suction outlet to optimize removal of necrotic tissue so as to ultimately to promote wound healing.
