SURGICAL STAPLING DEVICE Abstract A surgical stapling device (10) is disclosed for the treatment of internal haemorrhoids. The surgical stapling device includes a handle portion (12), an elongated 5 body portion (14) and a head portion (16) including an anvil assembly (30) and a shell assembly (31). 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 anvil assembly of the io stapling device may include an approximation mechanism having an anvil retainer including an elongated distal extension dimensioned to be telescopingly received within a longitudinal bore of an anvil center rod of the anvil assembly. The elongated distal extension is of a length to provide telescopic engagement with the anvil center rod without obstructing visualization of the surgical site. A kit including a surgical is instrument having a removable anvil assembly and an anvil assembly insertion handle is also disclosed. The kit may also include a speculum, an anal dialator and/or an obturator.
