Karazin popup.description2 A research object is patients with ulcerous illness of stomach and duodenum, cancer of rim and direct bowel. Research methods are clinical researches of ultrasonic scalpel on biological tissue , morphological study of fabrics in the area of ultrasonic dissection, research of haemostatic properties (typing of collogens and immune changes). In basis of the real research comparative experimentally-morphological and clinical and morfological research of changes is fixed in the hollow organs of gastroenteric highway, what be going on after application physical methods of dissection and coagulations of fabrics with the use of different types of energy (electric and ultrasonic), and also influence of these methods on a flow and end of reparative processes in the operating field. Possibilities and features of influence were studied on fabric of the followings options: - electrosurgical vehicles: "EN-57I", "Efa-0201", Russia; Karl Storz, Germany; - ultrasonic surgical setting of "Harmonic scalpel Ultracision",Ethicon Endo Surgery, the USA. An electrosurgical block worked in the monoarctic mode. Frequency of current was 650 kHz, launch power - 90 W. As working attachment electrode and electrode was utillized in form marble. Choosing the range of work of the ultrasonic setting we came from that during work of ultrasonic scalpel in the mode of high power there is an in a greater degree dissecting effect and in less. And vice versa, than less than power, the weaker scission and anymore coagulation. Taking into account these information, an ultrasonic scalpel was utillized in the mode of a 1 power-level with working attachment as scissors. With the purpose of got results, in experimental and clinical work we were utillize the identical parameters of work of apparatus and types of workings attachments.
