NEWLY DEVELOPED ULTRASONIC ASPIRATOR AND ITS APPLICATION FOR ENDOSCOPIC SURGERY

The authors have developed an ultrasonic aspirator to assist in urolog ic endoscopic surgery. It appeared that ultrasonic aspiration of bladd er tumors was clinically efficient in transurethral surgery. Tumors 1 to 2 cm in diameter could be aspirated completely with this instrument alone. The application of the ultrasonic aspirator, which has also be en designed with a coagulating function, to laparoscopic lymphadenecto my was evaluated. A special probe sheath was used to insulate it when using coagulation current. During operation, perivascular fatty tissue was removed safely with the aspirator. In the near future, the ultras onic aspirator will be one of the most effective tools in laparoscopic surgery.
