Abstract

A multi-tool surgical apparatus is provided which includes a handle assembly, a body portion extending from the handle assembly and a plurality of different tool assemblies operatively associated with the body portion and actuable independent from one another each for performing a different surgical task during endoscopic or laparoscopic procedures. Preferably, a first surgical tool is operatively associated with a distal end of the body portion and a second surgical tool is operatively associated with a medial section of the body portion.

Claims

1. A multi-tool surgical apparatus comprising:

a) a handle assembly;

b) a body portion extending from said handle assembly and defining a longitudinal axis;

c) first tool means operatively associated with a distal end portion of said body portion for performing a first surgical task;

d) second tool means different from said first tool means associated with said body portion and disposed proximal of said first tool means for performing a second surgical task;

e) first control means for actuating said first tool means; and

f) second control means for actuating said second tool means, at least one of said first and second control means disposed in axial alignment with said body portion, said second control means comprises an axial drive screw assembly including a progressively advanceable drive screw and a control rod, said rod extending from said drive screw through said body portion to said second tool means.

2. A multi-tool surgical apparatus as recited in claim 1, further comprising rotation control means for rotating said body portion about the longitudinal axis thereof relative to said handle assembly.

3. A multi-tool surgical apparatus as recited in claim 2, further comprising means for selectively locking said rotation control means in a desired angular position.

4. A multi-tool surgical apparatus as recited in claim 1, wherein said first tool means comprises a pair of cooperating jaw members movable between an open position and a closed position.

5. A multi-tool surgical apparatus as recited in claim 4, further comprising means for selectively maintaining said jaw members in a desired position.

6. A multi-tool surgical apparatus as recited in claim 1, wherein said second tool means comprises a plurality of interleaved cooperating blade members movable between an open position and a closed position.

7. A multi-tool surgical apparatus as recited in claim 1, wherein said first control means comprises a pivoting actuation handle and a reciprocating control shaft operatively connected to said pivoting handle, said shaft extending through said body portion to said first tool means.

8. A multi-tool surgical apparatus as recited in claim 1, wherein said body portion extending from said handle assembly is tubular in configuration.

9. A multi-tool surgical apparatus comprising:

a) a handle assembly;

b) a rotatable tubular body portion extending from said handle assembly and defining a longitudinal axis;

c) rotation control means for rotating said tubular body portion about the longitudinal axis thereof relative to said handle assembly;

d) locking means for selectively locking said rotation control means in a desired angular position;

e) a pair of cooperating jaw members operatively associated with a distal end of said tubular body portion and movable between an open position and a closed position for performing a first surgical task;

f) first actuation means for moving said jaw member between said open position and said closed position;

g) a plurality of cooperating interleaved substantially planar blade members operatively associated with a medial section of said tubular body portion and movable between an open position and a closed position for performing a second surgical task; and

h) second actuation means for moving said interleaved blade members between said open position and said closed position.

10. A multi-tool surgical apparatus as recited in claim 9, wherein said first actuation means comprises a pivoting actuation handle and a reciprocating control shaft operatively connected to said pivoting handle, said shaft extending through said tubular body portion to said pair of cooperating jaw members.

11. A multi-tool surgical apparatus comprising:

a) a handle assembly;

b) a tubular body portion extending from said handle assembly and defining a longitudinal axis;

c) a pair of cooperating jaw members operatively associated with a distal end of said tubular body portion and movable between an open position and a closed position for performing a first surgical task;

d) first actuation means for moving said jaw members between said open position and said closed position;

e) means for selectively maintaining said jaw members in a desired position;

f) plurality of cooperating interleaved substantially planar blade members operatively associated with a medial section of said tubular body portion and movable between an open position and a closed position for performing a second surgical task; and

g) second actuation means for moving said interleaved blade members between said open position and said closed position.

12. A multi-tool surgical apparatus as recited in claim 11, wherein said first actuation means comprises a pivoting actuation handle and a reciprocating control shaft operatively connected to said pivoting handle, said shaft extending through said tubular body portion to said pair of cooperating jaw members.

13. A multi-tool surgical apparatus comprising:

a) a handle assembly;

b) a tubular body portion extending from said handle assembly and defining a longitudinal axis;

c) a pair of cooperating jaw members operatively associated with a distal end of said tubular body portion and movable between an open position and a closed position for performing a first surgical task;

d) first actuation means for moving said jaw members between said open position and said closed position;

e) a plurality of cooperating interleaved substantially planar blade members operatively associated with a medial section of said tubular body portion and movable between an open position and a closed position for performing a second surgical task; and

f) second actuation mean for moving said interleaved blade members between said open position and said closed position, said second actuation means comprises an axial drive screw assembly including a progressively advanceable drive screw assembly including a progressively advanceable drive screw and a control arm extending from said drive screw through said tubular body portion to said plurality of interleaved cooperating substantially planar blade members.

14. A multi-tool surgical apparatus as recited in claim 13, wherein said first actuation means comprises a pivoting actuation handle and a reciprocating control shaft operatively connected to said pivoting handle, said shaft extending through said tubular body portion to said pair of cooperating jaw members.

15. A multi-tool surgical apparatus comprising:

a) a handle assembly;

b) a elongated rotatable body portion extending from said handle assembly and defining a longitudinal axis;

c) rotation control means for rotating said body portion about the longitudinal axis thereof relative to said handle assembly;

d) locking means for selectively locking said rotation control means in a desired angular position;

e) a first tool mechanism operatively associated with a distal end portion of said body portion, said first tool mechanism movable upon activation of said handle assembly;

f) a second tool mechanism disposed proximal of said first tool mechanism; and

g) means positioned distally of said handle assembly in axial alignment with said body portion for moving said second tool mechanism.

16. A multi-tool surgical apparatus comprising:
