A surgical stapling instrument (1) comprises a body portion (2, 3), a handle (4) and a staple fastening assembly (8). The staple fastening assembly (8) includes a curved cartridge (10), which comprises at least one curved open row of staples, and a curved anvil (22), which is adapted to cooperate with the cartridge (10) for forming the ends of the staples exiting from the cartridge (10). The staple fastening assembly (8) is adapted to allow unobstructed access towards the concave inner faces of the cartridge (10) and the anvil (22). The cartridge (10) can be moved towards the anvil (22) from a spaced position for positioning tissue therebetween to a closed position for clamping the tissue. Preferably, a knife is contained within the cartridge (10) and is positioned such that there is at least one row of staples on at least one side of the knife.

An anoscope adapted for the suturing of hemorrhoids during a hemorrhoid removal procedure is disclosed. The anoscope has a distal conical tip, a channel body extending proximally from the distal conical tip and a flange radiused outwardly from the channel. A slot is formed in the channel body and runs longitudinally from the distal conical tip through the flange and is flanked by a pair of mutually opposed finger wings that extend out from the flange. The finger wings each have a distal finger wing tip and a concave surface embedded within the finger wing tips. The concave surfaces are sized for the placement of a finger of a user therein.

摘要:
A method for performing trans-anal resection is achieved by applying a first stitch about the rectum, wherein deep bites of the first stitch capture and fold a rectum wall, creating a longitudinal staple line in the rectal wall at a position adjacent the first stitch, positioning a curved surgical stapler instrument in the rectum for capturing the rectal wall held by the first stitch, firing the surgical stapler instrument creating a circumferential first staple line approximately along the arc defined by the first stitch, and repeating the procedure about the circumference of the rectum until a predetermined portion of the rectum is fully resected.
