Abstract
A surgical stapling instrument is provided which employs a highly pressurized gas as its source of energy. The highly pressurized gas is conducted to means for indicating the presence of the pressurized gas and to a pressure regulator. The pressure regulator controllably develops gas pressurized to a desired operating pressure. The pressure regulator supplies gas at a fixed or variable pressure to a tissue clamping mechanism and to the trigger mechanism of the instrument. In response to actuation of the trigger mechanism gas at the desired stapling pressure is supplied to a stapling mechanism. In a preferred embodiment, pressurized gas is maintained at the stapling mechanism until the trigger mechanism is reset for a subsequent stapling procedure.
