SURGICAL STAPLING DEVICE
First Claim
1. An insertion handle for delivery of an anvil assembly within a tubular organ section, the anvil assembly including an anvil head assembly secured to an anvil center rod, the insertion handle comprising:
- an elongated shaft dimensioned to be positioned within a hollow tubular organ, the elongated shaft including a proximal end and a distal end; and
an attachment portion disposed adjacent the distal end of the elongated shaft, the attachment portion comprising structure for releasably locking the insertion handle to a portion of an anvil assembly;
wherein a portion of the attachment portion is configured and dimensioned for positioning within a bore of the anvil center rod of the anvil assembly.

Abstract
A surgical stapling device is disclosed for the treatment of internal hemorrhoids. 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 anvil assembly of the 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 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.
