Principles and initial experience of a new device for dissection and hemostasis.
Electrosurgery is a commonly used technology in laparoscopy. Electrosurgical devices are being used in many medical subdisciplines in order to coagulate, cut, and ablate tissue and to produce hemostasis. The latest advance in electrosurgery is the introduction of novel simultaneous hemostatic sealing and cutting bipolar devices that minimize force by delivering energy as high current and low voltage output. One of these systems is the Gyrus Plasma Trissector (GPT), (Gyrus Group PLC, Gyrus International, Ltd.UK), a novel radiofrequency (RF) system based on bipolar technology, which consists of a proprietary PlasmaKinetic (PK) generator and specific instruments, designed as a system. The instrument consists of a 17 mm long gold-coated curved jaw with a ceramic insulated cutting element. The PK system uses high-powered pulsed bipolar energy to produce a plasmakinetic field around the working elements and is designed to operate at temperatures that allow effective tissue dissection but result in minimal collateral damage and adherence to tissue. The GPT was used with the Gyrus G400 WorkStation generator in laparoscopic radical prostatectomies (LRP). Our initial experience with this novel bipolar device demonstrates it to be safe and effective in dissection and hemostasis. The GPT permits us to act quickly when bloody fields are present, improves coagulation, reduces or eliminates sticking, seals large vessels such as dorsal vein complex (DVC) and allows secure grasping and dissecting of tissue. The urologist is familiar with electrosurgery, as we have become comfortable using GPT to dissect, cut, and coagulate tissue. We feel that the GPT can be used in a variety of laparoscopic procedures in urology.
