The working principle of PK plasma knife is to use the principle of steam pulse to produce a cooling effect when the energy intermittent, reduce thermal damage, so that the tissue and the instrument is not easy to adhere, there are digital and sound to provide the time that can be coagulated can be cut, when the tissue is completely coagulated, the system provides visual and auditory feedback in time in order to achieve the best coagulation effect, the generator can recognize the different special instruments, automatic setting of the energy output, no need for adjustment! The generator recognizes different specialized instruments and automatically sets the energy output without adjustment. With less than 1mm of thermal spread, it can permanently close blood vessels up to 7mm. Comparison to conventional electrocautery: Bipolar electrocautery output rarely optimizes the performance characteristics of specialized instruments, which can reduce clinical speed and increase the rise in temperature around the instrument, which can lead to tissue adhesion to the instrument. The electrocoagulators on the Gyrus Electrocoagulation Instrument have features that differentiate them from conventional bipolar motors, as demonstrated by the following (1) Vapor Pulsed Coagulation (VPC): VPC uses a focused pulse of energy from a steam to produce controlled coagulation of the blood vessel. VPC can only be used with Gyrus' specially designed electrocoagulation instruments, and it grabs the tissue that will be coagulated, distinguishing it from conventional bipolar motors. How the PK Plasma Knife Works and Its Benefits
(2) PK Tissue Cutting (PK): The energy of the PK output mode is used around the unipolar pole of Gyrus' PK BILAP instruments to produce an ionized plasma. Dependent on the selected electrocoagulation output, this "activated" pole provides tissue cutting and simultaneous hemostasis. This mode utilizes the conductive properties of fluids, including tissue fluid and saline. The advantages are that the PK knife is far less damaging to the surrounding tissue than an electrosurgical knife, and its precise cutting action allows it to safely separate and cut alongside vital organs and large blood vessels; less smoke and less burnt scabs allow for a clearer view of the laparoscopic procedure, shortening the operative time and minimizing the occurrence of complications.
