Bone drill
First Claim
1. 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 offset from the first longitudinal axis, the offset angle ranging from 5 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 offset from 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 along a transverse axis relative to the first, second and third longitudinal axes, the tubular sheath including a distal end configured to engage 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.

Abstract
A radiolucent bone drill and/or impact drill is provided, which includes a first portion connected to a second portion. The first portion defines a first axis and the second portion defines a second axis. The second axis is disposed at an angle relative to the first axis. A third portion is connected to the second portion. The third portion has a shaft extending therefrom. The shaft includes a distal end configured to engage bone. The bone drill may include a radiation protection guard mounted to the first portion. Specific drill bits, access sheaths/conduits/tube, curettes, and screwdriver bits designed to be used with the devices are provided. The bone drill may be used to place an access sheath/conduit/tube/needle into a bone in a single step. Methods of use are also disclosed.

18. 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.
