Abstract: A surgical apparatus for use in endoscopic surgery having a user interface operatively coupled to an articulating tool assembly via an elongate tubular member. Movement at the articulating tool directly corresponds to movement at the user interface thereby providing intuitive operation of the surgical apparatus. The apparatus is configured such that the range of motion of the articulating tool assembly emulates the range of motion of the human wrist.

Abstract: A method for using a trocar assembly for transstomal endoscopic procedures. The method comprises the steps of providing a trocar comprising a handle and a tubular cannula extending from the handle, the handle defining an operating channel continuous with a lumen of the cannula, wherein an annular balloon is disposed on the outside of the cannula; inserting the distal end of the trocar cannula into the stoma and advancing the trocar until the annular balloon is inside the stoma; and inflating the annular balloon to sealingly engage the opening of the stoma.
