Clinical application of a cordless laparoscopic ultrasonic device, "Beyond the Abstract," by Fernando J. Kim, MD, FACS, et al

BERKELEY, CA ( - Minimally invasive surgery (MIS) is a fast-growing field in urology. With the introduction of laparoscopic procedures in the arsenal of therapeutic options, a variety of new devices have been developed intending to improve surgical outcomes and/or help surgeons in ergonomics.[1] MIS has altered the way surgeons interact within the surgical field. Surgeons and patients are faced with numerous ergonomic challenges with respect to instruments and endoscopes. The prolonged and frequent use of laparoscopic equipment raises ergonomic risks that may cause physical distress for surgeons.[2] The use of laparoscopy, ultrasonic dissectors, intraoperative ultrasound, lasers, and other medical equipment increases patient safety and surgical outcomes. However, new technological equipment occupies a significant amount of space but is required in modern operating rooms.

In our recent article, we described the first clinical use of a Sonicision™ cordless ultrasonic dissector (SCUD) (Covidien-Mansfield, MA USA) after FDA approval.[3] The SCUD is a 5-mm cordless energy-based dissector designed for laparoscopic surgery. It utilizes reusable batteries, and the generator is placed in the hand-piece of the instrument. The instrument enables dual-mode energy for coagulation and cutting in the same button, eliminating the need for pedals or a two-button device.

We performed two procedures (one laparoscopic radical nephrectomy and one pelvic lymphadenectomy) to evaluate the device, and a non-validated questionnaire was performed by the surgical team (four surgeons and three scrub technicians). The ability to assemble the device, ability to pass the device to other members of the surgical team, space saved in the operating room, and overall satisfaction were classified as satisfactory by all surgical staff present at the procedure.

For each case, one battery was sufficient for the entire procedure. We did not run the battery low enough to activate the warning signal which switches on when 20% of the battery is remaining. The dual-mode energy button was evaluated by the surgical team as intuitive and safe. There was no inadvertent activation of the cutting setting under 181 activations on the coagulation mode.[3]

Plume generation is another concern for visibility during laparoscopy.[4, 5] Previously, we described plume generation from the SCUD as minimal compared to other non-cordless devices.[6]

We performed the first clinical use of a cordless ultrasonic dissector with success. The cordless technology satisfied staff regarding fast and easy assembly and safe use for patients and surgeons. Surgeons must encourage and help companies develop new surgical tools to improve ergonomics, patient safety, and surgical outcomes.
