Abstract

At least one embodiment is directed toward one or more disposable devices suitable for use in a surgical field of an operating room. One device includes a sensor communicatively coupled to a wand to register points of interest on a first or second bone of a muscular-skeletal system and transmits location data related to the points of interest to the sensor to assess orthopedic alignment with the points of interest.

Claims

1. A system for measuring an alignment of a muscular skeletal system in an operating room comprising:

a display, where the display shows at least a portion of the muscular skeletal system to be aligned;

a sensor wherein the sensor includes an accelerometer configured to measure axial tilt of the sensor and wherein the sensor includes a receiver of a trigger system; and

a wand wherein the wand includes an accelerometer configured to measure axial tilt of the wand, wherein the sensor is line of sight to the wand, wherein the sensor and the wand are configured to measure alignment of the muscular-skeletal system, wherein the wand includes a transmitter of the trigger system, and wherein a trigger signal transmitted by the trigger system is faster than a signal transmitted between the sensor and the wand.

2. The system of claim 1 further including a digital signal processor coupled to the display and voice recognition software coupled to the digital signal processor for assessing an acoustic signal received by a transducer.

3. The system of claim 2 where the voice recognition software identifies one or more words corresponding to an action and where a visual or auditory queue is provided in response to the identified words.

4. The system of claim 3 where a response is provided to the visual or auditory queue to initiate the action or terminate the action.

5. The system of claim 1 wherein the trigger signal initiates a measurement process.

6. The system of claim 5 wherein the signal transmitted between the sensor and the wand is emitted simultaneously with the trigger signal.

7. The system of claim 6 wherein the trigger signal is a pulse.

8. The system of claim 1 wherein the display is configured to support 3D mapping of the muscular-skeletal system in physical space.

9. The system of claim 1 wherein the display is configured to illustrate movement of the muscular-skeletal system in real-time.

10. The system of claim 1 wherein the display is configured to display a range of motion of the muscular-skeletal system and alignment.

11. An intra-operative system for an operating room comprising:

an ultrasonic alignment system configured to have at least one component coupled to a musculoskeletal system within a surgical field wherein the ultrasonic alignment system comprises a sensor and a wand, wherein the wand includes an accelerometer configured to measure axial tilt of the sensor, wherein the sensor includes an accelerometer configured to measure axial tilt of the sensor, wherein the ultrasonic alignment system includes a trigger system configured to emit a trigger signal between the wand and the sensor, and wherein a signal emitted between the sensor and the wand is emitted simultaneously with the trigger signal, wherein the trigger signal is faster than the signal emitted between the sensor and the wand;

a prosthetic component having a sensor, wherein the sensor is configured to measure a parameter, wherein the prosthetic component couples to the musculoskeletal system, and wherein the alignment system is configured to measure alignment of the musculoskeletal system; and

a display configured to show a portion of the musculoskeletal system and the measured parameter wherein the display includes a processor and wherein the display is configured to receive measurement data from the ultrasonic alignment system and the prosthetic component.

12. The system of claim 11 further including:

a transducer for receiving audio signals;

a digital signal processor operatively coupled to the ultrasonic alignment system, the sensor, the transducer, and the display wherein voice recognition software is operatively coupled to the digital signal processor and wherein the voice recognition software is configured to assess audio signals received by the transducer.

13. The system of claim 11 wherein the trigger signal and the signal emitted between the sensor and the wand are pulses.

14. The system of claim 11 wherein the display is configured to support 3D mapping of the muscular-skeletal system in physical space.
