Multifunctional grasping instrument with cutting member and operating channel for use in endoscopic and non-endoscopic procedures
First Claim
1. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity comprisinga handle;
- an elongate member having a proximal end coupled with said handle for being disposed externally of the anatomical cavity and a distal end for being disposed within the anatomical cavity;
a pair of opposed, relatively movable jaws carried at said distal end of said elongate member;
said jaws defining a grasping portion operable by manipulation of said handle to grasp objects in the anatomical cavity;
said jaws defining a cutting portion operable by manipulation of said handle to cut objects in the anatomical cavity;
an operating channel defined along said elongate member and having an open proximal end adjacent said proximal end of said elongate member and an open distal end adjacent said distal end of said elongate member to define a passage communicating between an exterior of the anatomical cavity and an operative site in the anatomical cavity when said distal end of said elongate member is positioned within the anatomical cavity; and
a valve disposed along said operating channel to control access to the operative site through said operating channel.

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.

25. A method of performing a surgical procedure in an anatomical cavity comprising the steps of
introducing an elongate member with opposed, relatively movable jaws at a distal end through an opening in a wall of the anatomical cavity; -
utilizing a first portion of the jaws to cut an object at an operative site in the anatomical cavity; and accessing the operative site from outside the body using an operating channel defined along the elongate member. - View Dependent Claims (26, 27, 28)
