Endoscopic diverticulotomy by harmonic scalpel (Ultracision): an experimental model

[Cochlear implants using the Ultracision harmonic scalpel].

We have evaluated the utility, indications and disadvantages of the Ultracision harmonic scalpel, in the cochlear implants, and his advantages compare to other electrocoagulation's systems. These aspects were evaluated in 50 cases of cochlear implants, made along the last years. We concluded that the Ultracision harmonic scalpel is indicated, mainly, in the otology field, in these situations in...

Thyroid surgery with a harmonic scalpel: an experimental study

BACKGROUND The goal of the study was to determinate the safety of the harmonic scalpel, widely used in thyroidectomy, near the recurrent laryngeal nerve (RLN). METHODS The study involved ten pigs of either sex. Twenty RLNs at risk were dissected using the new harmonic scalpel FOCUS. The distances between the nerve and the activated instrument were checked with a millimeter ruler. After dissec...

Renal sparing surgery using focus ultracision harmonic scalpel in patients with bilateral wilms' tumor: case report.

BACKGROUND Bilateral Wilms' tumor is rare and surgical treatment requires an individual approach. Surgical approach to the tumors located in the central part of the kidney represents a major challenge and nephrectomy is usually essential. Renal sparing surgery is difficult in such cases. CASE REPORT We describe a 3 year-old female patient with bilateral Wilms' tumor arising in the central loc...

Total Laparoscopic Hysterectomy with Harmonic Ultracision

The ultrasonic harmonic scalpel for circumcision: experimental evaluation using dogs.

Male circumcision is one of the most commonly performed operations worldwide, and many novel techniques have been developed for better postoperative outcomes. The purpose of this study was to explore the feasibility of applying the ultracision harmonic scalpel (UHS) for circumcision by using dogs. Sixteen adult male dogs were divided into two groups: the UHS group and the control group. The dog...
