Abstract
A detachable anvil rod for use with an apparatus for circular fastening of hollow organs is provided. An elongated rod member has a proximal end portion, a distal end portion and an irregular surface portion intermediate the proximal and distal end portions. The irregular surface portion includes a plurality of grooves which define a plurality of raised ridges. The ridges are adapted to engage grasping surfaces of a grasping tool so as to minimize potential of slippage, thus enhancing the maneuvering procedure of the anvil rod about the operative site. The anvil rod also includes a narrowly configured mounting portion which enables the rod to be applied to and mounted within the distal end of the stapling apparatus from a variety of angular positions. An apparatus which incorporates the improved detachable anvil rod is also described.
