Abstract

Claims (33)

1. 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.

2. The medical device of claim 1 , wherein the first sensor is configured to instantaneously measure a distance of advancement of the working tool.

3. The medical device of claim 1 , further comprising a second sensor configured for outputting a second signal representative of passage of the working tool through varied layers of tissue having differences in material strength.

4. The medical device of claim 3 , wherein the second sensor is configured to prevent further axial penetration of the working tool when the second signal indicates passage of the working tool beyond a distal cortex while rotational movement of the working tool is allowed.

5. The medical device of claim 1 , wherein a distal end of the working tool is aligned with the distal end of the housing such that the distal end of the working tool and distal end of the housing are flush with one another.

6. The medical device of claim 1 , further comprising a drive rod extending through the housing and engaged with the rotational drive motor, wherein the first sensor comprises a transducer configured to rotate around the drive shaft.

7. The medical device of claim 1 , wherein the rotational drive motor is held rotationally still by anti-rotation conducting flanges.

8. The medical device of claim 7 , wherein the flanges are configured to slide within channels in the housing.

9. The medical device of claim 1 , further comprising an irrigation system configured to cool a surgical field while the medical device is in use.

10. The medical device of claim 1 , further comprising an irrigation system wherein the irrigation system includes one or more irrigation nozzles, an irrigation port, and an irrigation actuator.

11. 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.

12. 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.

13. The medical device of claim 12 , wherein the first sensor is configured to instantaneously measure a distance of advancement of the working tool beyond a distal end of a drill guide assembly.

14. 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.

15. The medical device of claim 14 , wherein the rotational drive motor is connected to the drive shaft by way of a detachable coupler.

16. The medical device of claim 14 , wherein the rotational drive motor is connected with the drive shaft when a release button is in a first position and wherein the rotational drive motor is disconnected from the drive shaft when the release button is in a second position.

17. The medical device of claim 14 , further comprising a coupler operatively coupled to the working tool, wherein the coupler is stabilized within the housing by bearings, the bearings axially slidable and stabilizing.

18. The medical device of claim 14 , wherein the coupler is configured to be rotatably driven.
