ABSTRACT

Objective To evaluate the dissection and hemostasis effects of harmonic scalpel in laparoscopic surgery. Methods The effect in patients underwent laparoscopic surgery with harmonic scalpel or with high frequency electricity scalpel was compared. Results All the operations were done by laparoscopy.No complications or massive blood loss occurred during and after operation.The average operation time ,blood loss of operation with harmonic scalpel were less than that with high frequency electricity scalpel. Conclusions Harmonic scalpel has precise cutting , controlled coagulation, and less tissue injury,it can increase the safety and microsurgery techinque of laparoscopic surgery.It is a very important equipmeat and useful for laparoscopic surgery .
