ABSTRACT:
A surgical stapling device is disclosed for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The head portion includes an anvil assembly including a tiltable anvil which will tilt automatically after the device has been fired and unapproximated. The tiltable anvil provides a reduced anvil profile to reduce trauma during removal of the device after the anastomoses procedure has been performed. The stapling device includes a bulbous indicator which preferably extends above a top surface of the handle assembly of the device. The indicator includes indicia to identify to a surgeon that the device has been approximated and is in a fire-ready position. Preferably, the indicator includes a cover which is formed of a magnification material to prominently display the indicia. The anvil assembly of the stapling device preferably includes a retainer clip positioned on the anvil head. The retainer clip preferably includes at least one resilient arm which is positioned to engage a cutting ring during unapproximation of the stapling device.
