ABSTRACT
The bleeding stoppage and the wound sanitation constitute an important problem of modern surgery. There is information presented concerning the apparatuses elaboration for the bleeding stoppage, processing of the soft living tissues wounds, including the infected, during surgical operations conduction, using high-temperature stream of air. The data adduced about the apparatuses trial and preclinical investigations of the method, realized with their help, had confirmed a high efficacy of hemostasis and sanation effects as well as significant reduction of the wounds processing time.

Second-harmonic output at 4.6-5.5 mum of the order of 6 mW with a 0.12% external conversion efficiency has been obtained by pumping a AgGaSe(2) crystal with a low-power cw CO(2) laser. The surface damage threshold of AgGaSe(2) for cw radiation was found to be inside the limit of 33-45 kW/cm(2) in the 9.2-10.8-mum wavelength region. Another important limitation of the pump power connected with a thermal lensing effect in crystal was determined experimentally. A comparison was made of AgGaSe(2) and ZnGeP(2) crystals as materials suitable for the efficient generation of the second harmonic of cw CO(2) laser radiation.
