The possibility of hepar resection by means of Soviet-made ultrasound device URSK-7N-18 was investigated in experiment on 13 mongrel dogs. The device was adapted to this surgery and was supplied with a special working part with a vacuum pump and channel for inspiration of liquid. The working part frequency is 26.5-30.0 kHz, resonance frequency is 26.5 kHz. The device does not damage blood vessels, nerves, and ducts but on the basis of morphology it provides both hemostasis at the early period after surgery owing to changes in microcirculation, and rapid wound healing by means of aspiration of necrotized tissues.
