Abstract

A method and apparatus for use in manipulating material during a medical procedure includes positioning the material in engagement with a major side surface on a distal end portion of a shaft. A gripper is operated to grip the material between a wire and a major side surface of the shaft by moving the wire along a longitudinal central axis of the shaft. Material is moved to a desired position relative to a patient'"'"'s body while the material is gripped between the wire and the major side surface of the distal end portion of the shaft. The wire is then retracted along the longitudinal central axis of the shaft to release the material for movement relative to the end distal end portion of the shaft.

Claims

1. A tool for manipulating material during a medical procedure, the tool comprising:

a handle;

a shaft extending from the handle, said shaft having a distal end portion with a major side surface which is engagable with the material during the medical procedure; and

a gripper movable along a longitudinal central axis of said shaft to grip the material between said gripper and said major side surface of said distal end portion of said shaft.

2. A tool as set forth in claim 1 further including a shoulder which is disposed between said distal end portion of said shaft and a proximally extending portion of said shaft, said shoulder being engagable with the material to retard movement of the material in a proximal direction relative to said shaft.

3. A tool as set forth in claim 1 wherein said handle includes an actuator which is manually actuatable to move the gripper along the longitudinal central axis of the shaft.

4. A tool as set forth in claim 1 wherein said shaft is manually bendable to any one of a plurality of configurations to facilitate positioning of the material during the medical procedure.

5. A tool as set forth in claim 1 wherein said shaft has a tubular body which extends in a proximal direction from said distal end portion of said shaft, said distal end portion of said shaft being integrally formed as one piece with said tubular body, said gripper includes a wire which is at least partially disposed in said tubular body and is axially movable along said tubular body.

6. A tool as set forth in claim 5 wherein said wire extends from said tubular body and along said distal end portion of said shaft to enable the material to be gripped between said wire and said distal end portion of said shaft.

7. A tool as set forth in claim 6 wherein said wire is movable from an extended position extending along said distal end portion of said shaft toward said tubular body to decreases the extent to which said wire extends along said distal end portion of said shaft and to release the material for movement relative to the shaft.

8. A tool as set forth in claim 1 wherein said gripper includes a wire which is movable along said shaft and which has a distal end portion which extends across and is spaced from a portion of said major side surface of said distal end portion of said shaft to enable the material to be gripped between said distal end portion of said wire and said major side surface of said distal end portion of said shaft.

9. A tool as set forth in claim 1 said major side surface of said distal end portion of said shaft is flat.

10. A tool as set forth in claim 1 wherein said major side surface of said distal end portion of said shaft has an arcuately curving configuration as viewed in a plane extending perpendicular to the longitudinal central axis of said shaft.

11. A tool as set forth in claim 1 wherein a first portion of said major side surface of said distal end portion of said shaft has a flat configuration and a second portion of said major side surface of said distal end portion of said shaft has an arcuately curving configuration.

12. A tool as set forth in claim 1 wherein said gripper has a circular cross sectional configuration as viewed in a plane extending perpendicular to a longitudinal central axis of said gripper.

13. A tool as set forth in claim 1 wherein said gripper has an arcuately curving cross sectional configuration as viewed in a plane extending along the longitudinal central axis of said shaft.

14. A tool as set forth in claim 1 wherein said gripper has a distal end portion which curves away from said major side surface of said distal end portion of said shaft.

15. A tool as set forth in claim 1 wherein said gripper includes a loop which extends across a portion of said major side surface of said distal end portion of said shaft.

16. A method of positioning material at a target anatomical location during a medical procedure, the method comprising the steps of:

providing a tool that includes a handle, a shaft extending from the handle, and a gripping mechanism operably coupled to the handle, the shaft having a distal end portion;

placing the material on a first major surface of the distal end portion of the shaft,

operating the gripping mechanism to apply a linear engaging force to the material so that the material is securely retained on the first major surface;

advancing the material to the target anatomical location; and

operating the gripping mechanism to remove the linear engaging force from the material thereby deploy the material at the target anatomical location.

17. The method of claim 16, wherein a portion of the shaft is shaped by a user, prior to the advancing step, so that the portion is dimensioned to traverse one or more anatomical features.

18. The method of claim 16, wherein the surgical procedure is a robotic-assisted surgery.

19. The method of claim 16, wherein the surgical procedure is a cranio-facial surgical procedure.

20. The method of claim 16, wherein the linear engaging force is removed from the graft without displacing the graft from the first major surface.

21. A method of positioning material during a medical procedure, said method comprising the steps of:

positioning the material in engagement with a major side surface on a distal end portion of a shaft;

moving a distal end portion of a wire in a first direction along a longitudinal central axis of the shaft into engagement with the material to grip the material between the distal end portion of the wire and the major side surface of the distal end portion of the shaft;

moving the material to a desired location relative to a patient'"'"'s body while the material is gripped between the distal end portion of the wire and the major side surface of the distal end portion of the shaft; and

moving the distal end portion of the wire in a second direction along the longitudinal central axis of the shaft to release the material for movement relative to the distal end portion of the shaft.
