[Electrosurgical device EKhBCh-25-1-C].

The outfit is intended for cutting, coagulation and microcoagulation of the biological tissue by high-frequency current during surgical interventions in stomatology. The outfit ensures smooth control of outlet power. It is fitted out with a timer for automatic time lag of electrosurgical exposure. The generator is triggered by pressing the pedal or push button of the electrode holder. The outfit is also equipped with a kit of instruments. A short technical specification of the outfit is given.

[Development of a high-frequency electrosurgical endoscopy apparatus].

A brief analysis has been made of the basic operational features of the high-frequency electrosurgical endoscopy apparatus (HFEA). Recommendations for choosing the output parameters are given, the solution of the problem of designing HFEA for endoscopy was considered by using the "Endotome-I" apparatus as an example.

[Effect of high-amplitude electrical impulses on the strength of the coagulative adhesion of the blood vessels].

Strength of coagulative commisure of the blood vessel tissues in their coagulation with high-frequency current can be increased after additional action of high-amplitude electrical pulses. A comparative test of commisures tensile strength confirmed its possible increase by 1.6--1.7 times when vascular tissues were preliminarily subjected to the action of short high-amplitude electrical pulses.

[New models of forceps for bipolar coagulation].

Operations on the brain require an optimum coagulation effect to be produced by forceps for bipolar coagulation. New forceps models are described in which the elimination of heat from the operating ends is considerably improved by making the whole forceps of copper and providing intermittent supply of high-frequency current to it. As a result the coagulation effect is distinguished by slight necrosis of the tissues adjoining the ends of the forceps and no sticking of these tissues to these ends.

[Improvement of effectiveness of high frequency electrosurgical equipment].

The paper summarizes the results of the activities of the All-Russian Research Institute of Medical Industry on the development of electric stimulating equipment for anesthesiology and the experience in its application. It also deals with electrostimulations, such as transcranial (transcerebral) electroanalgesia, transdermal (transcutaneous) electroneurostimulation, epidural (peridural) electrostimulation, perineural electric neurostimulation, testing electrostimulation of peripheral nerves in making regional anesthesia, electric neurostimulating testing of neuromuscular transmission. The developed monofunctional Delta-101, Delta-102, Delta-301, Synapse-1 electric neurostimulators and a polyfunctional Anestim-PF apparatus used in anesthesiological care and other related medical fields.

[Russian electrophysiotherapeutic apparatus. The problems of its design and production].

The topical organizational problems of design, production, and use of physiotherapeutical equipment (PTE) are discussed. PTE is considered to be basic tools employed in physiotherapy. The therapeutical effect of PTE on man is produced by currents of different frequency and shape by means of electrodes (which come in contact with a patient's body) or an electromagnetic field having different frequency-modulation characteristics via non-contact method by means of radiating elements. The devices which transform electromagnetic to mechanical energy may be subsumed under a separate group that includes ultrasonic therapeutical apparatuses, mechanical massage and mechanical stimulation equipment. The leading PTE designer is "VNNIMP-VITA Co. which has developed and launched about 20 varying = purpose PTE models into practice. The interest displayed by the conversed enterprises of the military industrial complex in the manufacture of medical equipment items and primarily PTE has recently caused unsystematic development of new PTE which have not been positively assessed and introduced into medical practice. New PTE models should be designed by strengthening the relations between those who design this type of medical equipment and the new structures of the Russian Academy of Medical Sciences.
