Abstract

With the YPCK-7H unit, serving as a base, a cryo-ultrasonic instrument for a combined use of cryogenic and ultrasonic methods has been constructed. A pipe for the passage of liquid nitrogen is mounted on an ultrasonic waveguide, this securing the cooling of the soft tissue subjected to the operation down to--135--80degreesC and separation of the tissues with the frequency of ultrasonic oscillations within a range of 20 to 45 kHz. The surgical cryoultrasonic instrument is apt to significantly increase the efficacy of hemostasis and helps achieve a still better neatness of the cut, this obviously being due to the cryogenic factor which adds advantage to the ultrasonic operative intervention.
