Bone drill

A bone drill comprising:

• an elongate tubular handle member defining a first longitudinal axis and having a proximal end and a distal end,
• an elongate tubular drive member defining a second longitudinal axis and having a proximal end and a distal end, the proximal end of the elongate tubular drive member being connected to the distal end of the elongate tubular handle member such that the second longitudinal axis is disposed at an angle ranging from 0 to 45 degrees relative to the first longitudinal axis;
• a cylindrical head portion connected to the distal end of the elongate tubular drive member, the cylindrical head portion defining a third longitudinal axis that is disposed at an angle relative to the first longitudinal axis, or at an angle offset from both the first and second longitudinal axes;
• a tubular sheath extending from the cylindrical head portion and configured for axial movement relative to the cylindrical head portion, the tubular sheath including a distal end configured to engage bone, the axial movement being spring driven to facilitate an impact engagement of the distal end and the bone;
• and
• a drill bit axially disposed within and extending along the length of the tubular sheath, the drill bit comprising a distal tip that extends past the distal end of the tubular sheath.
