IVANOVA et al. Originally published at The Paton Welding Journal №11 2012 Presented are the data illustrating advantages and areas of application of HF electric welding apparatus EK-300M1 in surgery. Keywords: electric welding, soft live tissues, highfrequency apparatus EK-300M1, area of application, advantages Development of equipment and technology for high-frequency electric welding (HFEW) of soft live tissues became a priority for Ukrainian scientists, engineers and doctors. In 1991 Prof. B.E. Paton and Prof. V.K. Lebedev put forward a hypothesis and proposed mathematical model which were proved by series of experiments on animals. This allowed stating a possibility of electric welding of soft live tissues with preservation of their viability. It is time to develop the laboratory samples of techniques and experimental substantiation of the technology [1]. For this purpose an international project was developed in 1996 under the leadership of Prof. B.E. Paton with assistance of the E.O. Paton Electric Welding Institute (PWI), A.A. Shalimov National Institute of Surgery and Transplantology, International Association «Welding» and commercial credit company «Consortium Service Management Group Technologies Inc.», as well as series of medical institutions of Ukraine. Common work was successful. The first variants of system with dosed power supply, prototypes of samples of power sources and surgical instruments were proposed at the beginning. Development of the power sources was stepwise. The first experimental variant was developed in 1992, the second in a period from 1995 to 1996, and the third one in 2003. EK-300M1 power source was developed in 2004 and its updated variant in 2007—2008 together with RI of Applied Electronics of NTUU «Kiev Polytechnic Institute» [2] and plant «Schyotmash» (Lubny, Poltava region). Experimental work was kept on during indicated periods in the PWI laboratories as well as in the clinics with assistance of the specialists of engineer and medical orientation. The first State Certificate about registration of HFEW apparatus EK-300M1 in Ukraine was issued in January, 2001. This is a date of beginning of practical application for new method of tissue saving HFEW technology in surgery. The further State Registration Certificates were issued in 2004 and 2010. The State Certificates about registration in the Russian Federation (2006) and in Belarus (2009) were also obtained. Technology, method of HFEW and welding instruments were patented in Ukraine, Russia, USA, European Union, Canada, China, Japan and Australia [3—15]. All these allowed proceeding to the application of method of soft live tissue welding in different spheres at the clinics of 16 regions of Ukraine as well as in Russia, namely, three Moscow and Saint-Petersburg clinics. Medical instruments being a constituent of the HFEW complex is developed simultaneously with work over the power source. Such main parameters as dimensions, form, weight of electrodes as well as requirement to design, i.e. comfortable operation, access to place of HFEW, workability of instrument in manufacture and repair are determined. All the types of electric welding medical instruments (forceps, clamps and laparoscopes) are the instruments of bipolar type. Instruments used for endoscopic and thoracoscopic surgical procedures are of a great interest. Experience of manufacture and practical application of such type of the instruments is accumulating. At that the experimental work is proceeded with and positive results are immediately transferred in the clinical conditions. View/download the full article.
