Surgical apparatus and detachable anvil rod therfor.

摘要

A detachable anvil rod 30 for use with an apparatus for circular fastening of hollow organs is provided. An elongate rod member has a proximal end portion 34, a distal end portion 52 and an irregular surface portion 48 intermediate the proximal and distal end portions. The irregular surface portion includes a plurality of grooves which define a plurality of raised ridges 50. The ridges are adapted to engage grasping surfaces of a grasping tool so as to mimimize 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 36 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. <IMAGE>
