Laparoscopic Nephrectomy Using the Harmonic Scalpel

Journal of Endourology, 1997
Laparoscopic nephrectomy is gaining popularity. Improved instrumentation is making surgery easier with fewer complications. Our first three laparoscopic nephrectomies using the Harmonic Scalpel were performed on two women and one man. The surgical indications were nonfunctioning kidneys (two left, one right) with hypertension in one patient and stone ...

Determination of the acoustic output of a harmonic scalpel

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2002
The acoustic output of a harmonic scalpel was experimentally determined, and both the airborne ultrasound and the ultrasound transmitted in water were taken into account. The sound pressure level of airborne ultrasound was measured with a microphone and an artificial head, so that the free-field value and the sound level at the entrance at the bottom ...

Utility of the Harmonic Scalpel for Laparoscopic Partial Nephrectomy

Journal of Endourology, 1998
Laparoscopic partial nephrectomy (LPN) remains a technically challenging procedure largely because of the lack of methods for obtaining consistent parenchymal hemostasis. The objective of this study was to determine if the extent of resection influences the ability of the harmonic scalpel to achieve hemostasis and to define the cases in which the ...

Ultrasonic (harmonic) scalpel tonsillectomy

Operative Techniques in Otolaryngology-Head and Neck Surgery, 2002
Significant postoperative pain and discomfort continues to be associated with a tonsillectomy procedure. Various instruments have been used over the years, but in an attempt to simplify the surgical procedure and minimize the postoperative morbidity, the ultrasonic (harmonic) scalpel uses high frequency piezoelectric technology to create intracellular ...

Laparoscopic Sterilization with the Harmonic Scalpel

Journal of Gynecologic Surgery, 1999
ABSTRACT The object of this study was to describe the surgical technique of laparoscopic sterilization with the harmonic scalpel. From April 1995 to July 1997, 30 women 26–41 years old underwent laparoscopic sterilization with the harmonic scalpel. The procedure was performed on an outpatient basis. The mean operative time was 7 min.
