SURGICAL ULTRASONIC INSTRUMENT FOR ABLATION OF PATHOLOGICAL MASS FROM BIOLOGICAL TISSUE, DEVICE FOR ABLATION OF PATHOLOGICAL MASS FROM BIOLOGICAL TISSUE AND METHOD WITH APPLICATION THEREOF

摘要

FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to means of carrying out low-invasive surgical operations. A surgical ultrasonic instrument contains coordinating and conducting elements for the transmission of an ultrasonic signal and a working end connected to the conducting element. The conducting element and/or working end have at least one section with different physical and/or mechanical properties, obtained by performing its thermal and/or mechanical treatment or made from a material, different from the material of adjacent section(s). A device for the ablation of a pathological mass additionally contains a generator of ultrasonic fluctuations and an acoustic unit. The method of the pathological mass ablation from a biological tissue consists in the application of the device for the pathological mass ablation.EFFECT: improvement of transmission of ultrasonic fluctuations, provision of sufficient dynamic stability of the ultrasonic instrument and control of the curvature of a trajectory of elastic deformation of the conducting element and working end of the ultrasonic instrument.27 cl, 13 dwg
