摘要： A method provides flow to multiple channels in an endoscope during an endoscope decontamination procedure. A member is inserted into a chamber in a body of an endoscope through an opening into the chamber, the chamber being intersected by a first lumen and a second lumen. The member separates fluidly the first lumen from the second lumen. Fluid is flowed through a first channel through the member into the first lumen and through a second channel through the member into the second lumen. Additional lumens can be so treated at the same time. Fluids can include detergents and other cleaning fluids, disinfectants and sterilants.

摘要： An apparatus and method for igniting plasma in a surgical system is disclosed. A corona discharge is generated on a surgical handpiece which is used to ignite a plasma arc for surgical operations. The advantages include greater reliability and repeatability of plasma arc ignition. The apparatus comprises a handpiece incorporating an active electrode, a passage for ionizable gas, and a corona return electrode. The corona return electrode has a terminus on the holder and near the distal end of the holder. The corona return electrode is electrically connected to the return path of the electrosurgical generator. A non-uniform electric field is generated between the active electrode and the corona return electrode of sufficient strength so that a corona is formed near the active electrode. A separate return electrode may be on the patient, or the apparatus may be configured for bipolar electrosurgical operation by carrying the return electrode on the handpiece. A dielectric material separates the active electrode and the corona return electrode. There is substantially capacitive coupling between the active electrode and the corona return electrode. There is substantially resistive coupling between the active electrode and the return electrode.

摘要： An electrosurgical apparatus for coagulating tissue includes an elongated flexible tube which extends through a working channel of an endoscope. A pressurized ionizable gas is supplied to the proximal end of the tube and is forced at a rate of greater than 1 liter per minute therethrough. The tube also includes at least one aperture located along the periphery of the tube and an angularly disposed surface located within the tube for redirecting the gas through the aperture and at the tissue. At least one electrode ionizes the gas prior to the gas exiting the aperture.
