Abstract
A bone drill guiding device including a drill entry part comprising a cannula having a distal end portion and sized to receive a bone drill, a drill exit part comprising a fixation tip portion and a coupling that rigidly couples the drill entry part and the drill exit part so that longitudinal axes of the cannula distal portion and the fixation tip portion are arranged on a single mutual axis. In some embodiments, the coupling is a linear sliding coupling that parallels the single mutual axis.
Claims34
A bone drill guiding device, comprising:
- a drill entry part comprising at least one curved cannula, each said cannula having a distal end portion and a cannula tip and sized to receive a bone drill;
- a drill exit part comprising a fixation tip portion comprising a fixation tip;
- and
- a coupling that rigidly couples said drill entry part and said drill exit part so that longitudinal axes of said cannula distal end portion of each said at least one curved cannula and said fixation tip portion are arranged along a single mutual axis extending between said cannula tip to said fixation tip.

A method of drilling a hole in bone comprising
- positioning a drill entry part of a bone drill guiding device comprising a curved cannula and a cannula tip against a bone at a desired drill entry point;
- axially slidingly coupling a drill exit part comprising a fixation tip portion having a fixation tip to said drill entry part;
- axially sliding said drill entry and drill exit parts towards each other and positioning said fixation tip portion against skin over a location at which said drill is expected to exit said bone;
- rigidly locking said drill entry part and said drill exit part together;
- and
- bringing longitudinal axes of a distal end portion of said cannula and said fixation tip portion to be arranged on a single mutual axis extending between said cannula tip to said fixation tip.
