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.

Claims

1. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity comprising

a handle;

and

an elongate tubular 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 and carrying a pair of opposed, relatively movable jaws;

said jaws defining a grasping portion operable by manipulation of said handle to grasp objects and a cutting portion operable by manipulation of said handle to cut tissue.

2. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said tissue cutting portion includes a blade.

3. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said tissue cutting portion includes a pair of blades carried by said jaws in opposed relation.

4. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said tissue 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 endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 2 wherein said blade is oriented parallel to a longitudinal axis of said elongate tubular member.

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

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

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

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

10. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said grasping portion is disposed distally of said cutting portion and wherein at least one of said jaws includes a concave portion between said grasping portion and said tissue cutting portion to hold an object during an endoscopic procedure without compressing the object.

11. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein at least one of said jaws includes a concave portion distally spaced from said tissue cutting portion to hold an object during an endoscopic procedure without compressing the object and wherein said grasping portion is disposed between said concave portion and said tissue cutting portion.

12. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said grasping portion is disposed distally of said tissue cutting portion and at least one of said jaws includes a concave portion proximally spaced from said tissue cutting portion to hold an object during an endoscopic procedure without compressing the object.

13. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said grasping portion is proximally spaced from said tissue cutting portion and at least one of said jaws includes a concave portion distally spaced from said tissue cutting member to hold an object during an endoscopic procedure without compressing the object.

14. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said grasping portion is proximally spaced from said tissue cutting portion and at least one of said jaws includes a concave portion disposed between said grasping portion and said tissue cutting portion to hold an object during an endoscopic procedure without compressing the object.

15. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein at least one of said jaws includes a concave portion proximally spaced from said tissue cutting portion to hold an object during an endoscopic procedure without compressing the object and wherein said grasping portion is disposed between said concave portion and said tissue cutting portion.

16. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said proximal and distal ends of said elongate tubular member are open and further comprising a valve disposed between said proximal and distal ends.

17. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 and further comprising a coupling carried at said proximal end of said elongate tubular member for connection with other medical instruments.

18. A multifunctional endoscopic instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said jaws are biased apart toward an open position and further comprising an outer tubular member disposed telescopically around said elongate tubular member and having a proximal end coupled with said handle and a distal end movable relative to said elongate tubular member by manipulation of said handle between a retracted position allowing said jaws to open and an extended position causing said jaws to close.
