Abstract
Abstract A multifunctional endoscopic instrument for use in performing endoscopic 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 tissue. In addition, the elongate tubular member defines a channel permitting fluids and other instruments to be communicated at the operative site without the need of having to remove the endoscopic instrument from the body.
