Abstract

A surgical instrument includes a forceps unit for being positioned within an anatomical cavity. The forceps unit includes a housing, an outer tubular member, an intermediate tubular member, and a handle mechanism coupled with at least one of the intermediate and outer tubular members for creating relative movement between the intermediate and outer tubular members. The outer tubular member has a proximal end mounted by the housing and terminates distally at a distal end. The intermediate member has a tubular body disposed telescopically within the outer tubular member, a proximal end mounted by the housing and a pair of opposed jaws disposed on a distal end of the tubular body resiliently biased apart such that relative movement of the outer tubular member distal end over the jaws causes the jaws to close. A channel or passage is defined through the instrument to permit an inner member having an end effector to be inserted therethrough.

Claims

1. A surgical instrument comprising

a tubular outer member having a proximal end and terminating distally at a distal end and having an operating channel defined therethrough;

an intermediate member having a body disposed at least partly within said outer member, said body having a proximal end and a distal end, a pair of opposed jaws each having a substantially flat grasping surface and being disposed on said distal end of said body and being resiliently biased apart;

a handle coupled with at least one of said jaws and configured to move said pair of opposed jaws between open and closed positions.

2. An instrument as recited in claim 1 wherein said body is tubular and said operating channel extends through said body.

3. An instrument as recited in claim 1, wherein said jaws are formed integrally with said body.

4. An instrument as recited in claim 1, wherein said jaws are formed separately from said body and are attached to said body by coupling means.

5. An instrument as recited in claim 1, wherein each of said jaws define a recessed portion and an insert is removably disposed in each recessed portion.

6. An instrument as recited in claim 2, further comprising an inner member movably disposed in said tubular body, said inner member having an end effector on a distal end for performing a medical procedure.

7. An instrument as recited in claim 1, wherein both of said jaws are movable.

8. An instrument as recited in claim 1, wherein one of said jaws is fixed and one of said jaws is movable.

9. An instrument as recited in claim 1, wherein at least one of said jaws has an arcuate portion formed therein for receiving tissue without compressing the tissue.

10. An instrument as recited in claim 1, further comprising a pair of opposed auxiliary jaws, said auxiliary jaws move in a plane that is transverse to a plane in which said jaws move.

11. An instrument as recited in claim 1, wherein said jaws have biopsy boxes formed therein.

12. An instrument as recited in claim 4, wherein a biopsy box is formed in said inserts.

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

a handle;

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 elongate tubular member defining a channel permitting access to an operative site within the anatomical cavity from outside the body;

said jaws being movable relative to one another by manipulation of said handle to perform grasping operations, each jaw having a substantially flat grasping surface.

14. A multifunctional instrument for use in performing procedures within an natomical cavity as recited in claim 13 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.

15. A multifunctional instrument for use in performing procedures within an anatomical cavity as recited in claim 13 and further comprising a coupling detachably coupled with said elongate tubular member for mounting said opposed, relatively movable jaws.

16. A multifunctional instrument for use in performing procedures within an anatomical cavity as recited in claim 13 wherein at least one of said jaws is electrically conductive and further comprising an insulated connector coupled with said electrically conductive jaw for connecting a cauterizing current to said blade.

17. A method of conducting a surgical procedure comprising the steps of:

introducing a member having a body and moveable jaws disposed on a distal end of said body into an area proximate tissue, each of said jaws having a substantially flat grasping surface;

manipulating the tissue with said jaws;

communicating with the area proximate the tissue through a channel defined through an outer member disposed around the member.

18. A method as recited in claim 17 wherein, in said communicating step, said channel passes through said body of said member.

19. A method as recited in claim 17 further comprising introducing an inner member having an end effector through said channel.

20. A surgical instrument comprising:

a tubular outer member having a proximal end and terminating distally at a distal end and having an operating channel defined therethrough;

an intermediate tubular member having a body disposed at least partially within the outer member, the body having a proximal end and a distal end and a pair of opposed jaws, each having a substantially flat grasping surface and being disposed on the distal end of the body and being resiliently biased apart; and

a handle coupled with at least one of the jaws and configured to move the pair of opposed jaws between open and closed positions.
