[Use of ultrasound and other modes of energy in therapy].

The paper reflects the results of studies made in the group "Ultrasound and Other Powers in Surgery" at the N. E. Bauman Moscow State Engineering University in designing new technologies and apparatuses for magnetic therapy, electric stimulation, electric analgesia, ultrasound therapy.

[Ultrasonic endarterectomy].

The authors used a generator of ultrasound oscillations and a special wave conductor in endarterectomy in the clinic and in the experiment. They assess positively the described method of endarterectomy.

[Ultrasonic skull trepanation].

Experimental ultrasonic cranial trepanation was performed on 60 albino rats by means of a semi-automatic device, Y3T-1. The trepanation is altraumatic and does not need any considerable physical effort. A histological examination showed that the zone of bone necrosis along the edge of the cut surface was one third to one half that developing with the use of electric and pneumatic surgical instruments.
