摘要： An ultrasonic medical treatment device has a casing, an elongate probe, a transducer assembly, a sheath and at least one electrode member. The probe is mounted to and extends from the casing and has an axis and a free end serving as an operative tip. The transducer assembly is mounted to the casing and is operatively connected to the probe for generating vibrations of at least one ultrasonic frequency in the probe. The sheath surrounds the probe. The electrode member is connectable to an RF voltage source and is mounted at least indirectly to the casing so as to permit relative motion between the electrode member and the probe.

摘要： A surgical device for ultrasonic ablation and RF cauterization includes a forceps member having at least one prong, the prong being formed as an electrode. At least one electrical connector is provided on the forceps member for operatively connecting the prong to an electrical power source. The surgical device further includes a mechanical connector attached to the forceps member for removably fastening the forceps member to a housing of an ultrasonic probe. The forceps member can thus function to carry out a cauterization procedure during a surgical operation utilizing the probe for ultrasonic ablation.

摘要： An ultrasonic medical probe comprises an elongate shaft formed integrally with a head portion having a distal end face oriented at least partially transversely to a longitudinal axis of the shaft. The shaft is provided with an internal longitudinal channel or bore extending to the end face. The end face is formed with an indentation communicating with the channel or bore at a distal end thereof, whereby liquid is guided over an extended surface of the end face relative to the channel or bore. The head portion also has a lateral surface extending substantially parallel to the longitudinal axis of the probe. The lateral surface is provided with at least one outwardly or radially extending projection. The projection enables the application of ultrasonic cavitation energy to a tissue surface that is in contact with the lateral or side surface of the probe head.
