A drill guide device for drilling straight tunnels through bone, the drill guide device having a hollow aiming tube with a curved end and a hollow receiving tube with a curved end. The aiming tube and the receiving tube are both attached to a curved frame for allowing angular adjustment between the aiming device and the receiving device. A rotating pin is inserted through the aiming tube, passes through the curved end and drills a straight tunnel through the bone where it is received into the receiving tube. The receiving tube forces the needle to curve rather than continuing on its straight path as determined by the tunnel through the bone. The curved aiming and receiving tubes allow a surgeon to work in an area which is "boxed in" by nerves, bones or the like which thereby would not allow the use of a straight drill guide. |
