An apparatus for use in surgical interventions for the purpose of the tissue removal.

摘要

The present invention relates to an equipment for use in surgical operations to remove tissue, and comprises an ultrasonic knife (101) having a tip intended to be brought into contact with the tissue, a transducer unit (107) causing said tip portion to oscillate longitudinally and a frequency generator (109) to drive the transducer unit (107), the parts of the ultrasonic knife (101) which are in contact with the patient being galvanically isolated from the other equipment of the knife, as well as means for temporarily supplying thermal energy to the tissue from the tip portion of the ultrasonic knife (101) in order to achieve hemostasis by means of coagulation.
