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.
Claims18
A medical drilling device comprising:
- a housing;
- a working tool near a distal end of the housing;
- a rotational drive motor operatively coupled to the working tool disposed in the housing;
- an actuator operatively coupled to the rotational drive motor disposed in the housing;
- and a first sensor interfaced with the working tool the first sensor disposed in the housing;
- wherein the first sensor is configured for outputting a first signal representative of advancement of the working tool relative to the distal end of the housing.

A medical drilling device comprising:
- a housing:
- a working tool near a distal end of the housing;
- a rotational drive motor operatively coupled to the working tool disposed in the housing;
- an actuator operatively coupled to the rotational drive motor disposed in the housing;
- and a first sensor interfaced with the working tool, the first sensor comprising a transducer, wherein the transducer comprises a bearing housing assembly, a light source, a code disc, a mask, a photodetector assembly, and an electronics board.

A medical drilling device comprising:
- a housing;
- a working tool near a distal end of the housing;
- a rotational drive motor operatively coupled to the working tool disposed in the housing;
- a first sensor interfaced with the working tool, the first sensor comprising a transducer within the housing;
- and
- a drill guide assembly is configured to move towards the distal end of the housing while the working tool is configured to remain fixed axially along the longitudinal axis to reveal a portion of the working tool beyond the distal end of the drill guide assembly to engage the bone.

A medical drilling device comprising:
- a housing;
- a working tool near a distal end of the housing;
- a rotational drive motor operatively coupled to the working tool disposed in the housing;
- a drive shaft within the housing and engaged with the rotational drive motor;
- a first sensor configured to output a first signal representative of advancement of the working tool;
- and
- a second sensor configured to output a second signal representative of passage of the working tool through varied layers of tissue having differences in material strength the second sensor configured to prevent further axial penetration of the working tool when the second signal indicates passage of the working tool beyond a distal cortex.
