The adjustable head of the drill guide allows a surgeon to drill a hole in the femur at an angle to a tunnel provided in the tibia. Because the surgeon can access the femur via the hole in the tibia, the surgical drill of the present invention obviates the need for a second hole in the tissue and also makes placement of femur hole more precise for securement of the ligament or tendon graft within the hole. ## Claims ### Claim 1 A surgical drill comprising: a drill guide; a guide pin; and a drill having an internal passage therein for said guide pin to releasably pass through; said drill guide comprising a body and a head rotatably mounted to said body at a stationary pivot point for permitting drilling along an axis x and thereafter also along an axis y; a longitudinal channel passing through said body and through said head for said guide pin to releasably pass through; said drill guide configured to bend said guide pin at an angle with respect to a longitudinal axis of said body. ### Claim 2 (depends on 1) The surgical drill of claim 1 wherein said drill guide further comprises an actuator for adjusting the angular orientation of the head with respect to the body. ### Claim 3 (depends on 2) The surgical drill of claim 2 wherein said actuator comprises: a rod; a screw having external threads; and a knob threadably connected to said screw; said rod directly connected at a distal end to the head and connected at a proximal end to the screw, such that rotation of said knob causes said screw and said rod to advance in a distal direction or retract in a proximal direction, further causing said head to rotate about the pivot point. ### Claim 4 (depends on 3) The surgical drill of claim 3 wherein said rod passes through the body of the drill guide. ### Claim 5 (depends on 3) The surgical drill of claim 3 wherein said rod is connected to said head at a point radially spaced from the pivot point such that linear movement of said rod translates into angular rotation of said head. ### Claim 6 (depends on 3) The surgical drill of claim 3 wherein clockwise rotation of said knob causes said screw and said rod to advance in a distal direction, further causing said head to rotate clockwise about said pivot point. ### Claim 7 (depends on 3) The surgical drill of claim 3 wherein counter-clockwise rotation of said knob causes said screw and said rod to retract in a proximal direction, further causing said head to rotate counter-clockwise about said pivot point. ### Claim 8 (depends on 1) The surgical drill of claim 1 wherein said guide pin is made of a flexible material. ### Claim 9 (depends on 1) The surgical drill of claim 1 wherein said drill is flexible. ### Claim 10 (depends on 1) The surgical drill of claim 1 wherein said drill guide further comprises a handle located adjacent to said body for a user to grasp. ### Claim 11 A drill guide comprising: a body; a head, rotatably mounted to said body at a stationary pivot point for permitting drilling along an axis x and thereafter also along an axis y; and an actuator for adjusting the angular orientation of the head with respect to the body, including a rod, screw and a knob threadably connected to said screw; said rod being directly connected at a distal end to the head and connected at a proximal end to the screw, such that rotation of said knob causes said screw and said rod to advance in a distal direction or retract in a proximal direction, further causing said head to rotate about the pivot point. ### Claim 12 (depends on 11) The drill guide of claim 11 further comprising a longitudinal channel passing through said body and through said head for releasably accepting a guide pin. ### Claim 13 (depends on 11) The drill guide of claim 11 further comprising a handle located adjacent to said body for a user to grasp. ### Claim 14 (depends on 11) The drill guide of claim 11 wherein said rod is connected to said head at a point radially spaced from the pivot point, such that linear movement of said rod translates into angular rotation of said head. ### Claim 15 (depends on 11) The drill guide of claim 11 wherein clockwise rotation of said knob causes said screw and said rod to advance in a distal direction, further causing said head to rotate clockwise about a pivot point. ### Claim 16 (depends on 11) The drill guide of claim 11 wherein counter-clockwise rotation of said knob causes said screw and said rod to retract in a proximal direction, further causing said head to rotate counter-clockwise about a pivot point.
