Cassette assembly with tubing loops

A surgical retractor assembly is provided comprising a frame having first and second portions, a first hook member supported on the frame, a second hook member supported on the frame and movable with respect to the frame, and a frame support supporting the frame. The frame support is adapted to retain the first portion of the frame in a selected raised position with respect to the second portion of the frame. The frame support preferably comprises two elongated shafts having locking mechanisms for locking the frame in the selected raised position.

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.
