Patent ID: 8187204

Claim:
A method of operating a surgical system that includes a surgical device having an outer cannula, comprising: configuring a remote valve between and in fluid communication with the surgical device and a pressure source; arranging the remote valve in a first position to fluidly connect the outer cannula to the pressure source, a pressure from the pressure source configured to cause the outer cannula to move to a pre-firing position; cocking the outer cannula of the surgical device internally into the pre-firing position by activating the remote valve to move a tissue receiving aperture disposed on the outer cannula proximally, the tissue receiving aperture extending through a sidewall of the outer cannula; arranging the remote valve in a second position to fluidly disconnect the outer cannula from the pressure source and cause the outer cannula to move distally from the pre-firing position to a fired position, wherein arranging the remote valve in the second position fluidly connects an inner cannula to the pressure source, the pressure from the pressure source configured to cause the inner cannula to move relative to the outer cannula; moving the inner cannula relative to the tissue receiving aperture while maintaining the outer cannula in substantially the fired position; and disconnecting the pressure source from both the inner cannula and the outer cannula when transitioning the remote valve between the first position and the second position.
