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.

4. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 1 wherein said cutting portion includes a blade carried by a first of said jaws and a recess formed in a second of said jaws in opposed relation to said blade to receive said blade when said jaws are moved toward one another.

5. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 2 wherein said blade is oriented parallel to a longitudinal axis of said elongate member.

6. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 5 wherein said blade is disposed along a central longitudinal axis of said elongate member.

7. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 5 wherein said blade is laterally offset from a central longitudinal axis of said elongate member.

8. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 2 wherein said blade is curved relative to a longitudinal axis of said elongate member.

9. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 2 wherein said jaws bend outwardly in a lateral direction relative to a longitudinal axis of said elongate member when closed together.

10. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 9 wherein said jaws are of curved configuration when closed together.

11. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 1 wherein said grasping portion is longitudinally spaced from said cutting portion to hold a needle.

12. A multifunctional instrument for use in performing endoscopic and open surgical procedures within an anatomical cavity as recited in claim 1 wherein said jaws include opposed concave portions longitudinally spaced from said cutting portion for defining an opening between the jaws to hold an object during a surgical procedure without compressing the object.
