EXPERIMENTAL EVALUATION OF BIOLOGICAL TISSUE COAGULATION USING BY OZONE-AIR PLASMA
The modern trend in medical physics, instrumentation and surgery is the development of new, effective and safe methods of hemostasis in surgical procedures. Currently, for these purposes there are different classes of electrosurgical devices. The aim of this study was to provide a process for the coagulation of biological tissues by exposure to the air-ozone plasma. To achieve the objectives of the experiment three were delivered, allowing to determine the effect of the time factor and the distance on the efficiency of coagulation, as well as to compare the experimental method of coagulation of biological tissue air-ozone plasma. The criteria for the effectiveness of coagulation were area and depth of coagulation necrosis. When exposed to air and ozone plasma for 5 seconds sequentially from a distance of 1.5, 10 millimeters necrosis area amounted to 6.58 mm, 7.16 mm, 7.06 mm and of necrosis depth - 1.15 mm, 1.11 mm and 0.7 mm. When exposed to air and ozone plasma from a distance of 5 mm consistently for 3, 7, 10 seconds necrosis area amounted to 6.58 mm, 8.08 mm, 7.91 mm and of necrosis depth - 1.13 mm, 1 15 mm, 1.35 mm. When exposed to air and ozone with plasma from a distance of 3 mm within 10 seconds respectively necrosis area was 8.16 mm, and the depth of necrosis - 1.55 mm, while under the influence electrocautery necrosis area was 3.35 mm, respectively, and the depth necrosis - 0.85 mm.
