First Claim
Patent Images
1. A tool for use during dual-bundle ligament reconstruction comprising:
- a body including a distal portion and a proximal portion, said body having a cannulated longitudinal shaft, said cannulation defining a first axis;
a locating feature formed at said distal portion and defining a locating surface, said locating surface defining a second axis arranged at a predetermined orientation relative to said first axis; and
wherein a first locating instrument extending through a first bone tunnel is adapted to rest against said locating surface of said groove to operatively align said first axis at said predetermined orientation thereby identifying a drill axis for preparation of a second bone tunnel.

Abstract
A tool and method for drilling a bone for receipt of a first and second bundle includes drilling a first tunnel in the bone. A locating instrument may be positioned into the first bone tunnel thereby defining a reference axis. A tool may be inserted through a portal defined in surrounding tissue. The tool may engage the locating instrument thereby identifying a relative orientation between the reference axis and the drill axis for preparation of a second bone tunnel. The second bone tunnel may be drilled along the drill axis.

8. A tool for use during dual-bundle ligament reconstruction comprising:
-
a first locating instrument defining a first longitudinal shaft portion having a first axis, a first reference head and a first distal tip portion; a second locating instrument defining a second longitudinal shaft portion having a second axis, and a second reference head; wherein said first locating instrument is adapted to be located into a first bone tunnel and wherein said second reference head of said second locating member is adapted to engage said first reference head to operatively align said second axis at a predetermined orientation thereby identifying a drill axis for preparation of a second bone tunnel. - View Dependent Claims (9, 10, 11, 12)
