Abstract
Abstract A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity includes a handle and an elongate tubular member having a proximal end coupled with the handle for being disposed externally of the anatomical cavity and a distal end for being disposed within the anatomical cavity and carrying a pair of opposed, relatively movable jaws. The jaws are operable by manipulation of the handle to grasp objects, such as needles, and to cut objects, such as suture material and tissue. In addition, the elongate tubular member defines an operating channel permitting fluids and other instruments to be communicated at the operative site without the need of having to remove the instrument from the body.
