Abstract
Disclosed are devices and methods for creating a bore in bone. The devices and methods described involve driving a rotating bit in an axial direction such that both rotation and linear movement are controlled and measurable. The instrument is useful for a surgeon to control and simultaneously measure the travel of the tool into the bone and prevent injury to surrounding structures.
Claims20
A method for creating a bore in bone, the method comprising:
- contacting an exposed surface of a bone with a distal end of a working tool operatively coupled to a medical drilling device;
- outputting a first signal by a first sensor of the medical drilling device representative of advancement of the working tool relative to a distal end of a housing of the medical drilling device, the first sensor disposed within a housing of the medical drilling device;
- and
- outputting a second signal by a second sensor of the medical drilling device representative of passage of the working tool through varied layers of tissue having differences in material strength.

A method for creating a bore in bone, the method comprising:
- contacting an exposed surface of a bone with a distal end of a working tool housed operatively coupled to a medical drilling device;
- outputting a first signal by a medical drilling device representative of advancement of a working tool relative to the distal end of a housing of the medical drilling device;
- and
- outputting a second signal representative of passage of the working tool through varied layers of tissue having differences in material strength by a second sensor wherein further axial penetration of the working tool is automatically prevented when the second signal indicates passage of the working tool beyond a distal cortex while rotational movement of the working tool is allowed.

A method for creating a bore in bone, the method comprising:
- contacting an exposed surface of a bone with a distal end of a working tool housed operatively coupled to a medical drilling device;
- outputting a first signal by a first sensor of the medical drilling device representative of advancement of the working tool relative to a distal end of a housing of the medical drilling device wherein the first sensor instantaneously measures a distance of the advancement of the working tool beyond a distal end of a drill guide assembly;
- moving a drill guide assembly towards the distal end of the housing while the working tool remains fixed axially along the longitudinal axis thereby revealing a portion of the working tool beyond the distal end of the drill guide assembly available to engage the bone;
- and
- outputting a second signal representative of passage of the working tool through varied layers of tissue having differences in material strength by a second sensor.

- and
- outputting a second signal by a second sensor of the medical drilling device representative of passage of the working tool through varied layers of tissue having differences in material strength wherein the second sensor is a torque sensor coupled to the rotational drive motor further comprising receiving torque readings of the rotational drive motor from the torque sensor to generate the second signal wherein the first sensor is a transducer further comprising measuring by the transducer the distance a drill guide assembly coupled to the medical drilling device travels, further comprising engaging an axial drive shaft extending through a region of the housing and with an axial drive motor configured to cause the drill guide assembly to travel in an axial direction wherein the axial drive shaft comprises a jack screw, a ball screw or a lead screw.
