Sensor based tracking tool for medical components
First Claim
1. A medical navigation system, comprising:
- a computing device having a processor coupled to a memory, a wireless communication component and a display for displaying an image;
a sensor module attached to a medical device, the sensor module including;
a housing for housing components of the sensor module and for attaching to the medical device, the housing including a fastening device to removably attach the sensor module to a surface of the medical device;
a processor housed in the housing;
a memory coupled to the processor;
a wireless communication component coupled to the processor;
a battery coupled to the processor;
a sensor coupled to the processor, the sensor including at least one of an accelerometer and a gyroscope;
wherein the sensor is configured to generate a signal representing movement of the medical device, the wireless communication component of the sensor module being configured to transmit the signal wirelessly;
a first set of tracking markers configured to be temporarily coupled to the medical device; and
a camera coupled to the computing device for detecting a location of the first set of tracking markers, the sensor module being free of any markers detectable by the camera;
wherein the computing device is configured to;
receive the signal from the sensor module via the wireless communication component of the computing device;
determine the initial position of the medical device based on the location of the first set of tracking markers detected by the camera and not based on the signal from the sensor module;
display an initial position of the medical device on the display;
when a line of sight from the camera to the first set of tracking markers is not available, update the display to reflect movement of the medical device subsequent to the initial position, using only the signal from the sensor module and not based on detection of any tracking markers by the camera; and
when the line of sight from the camera to the first set of tracking markers becomes available, further update the display, to reflect further movement of the medical device when the first set of tracking markers are detectable by the camera, based on detection of the first set of tracking markers by the camera and not based on the signal from the sensor module.

Abstract
A medical navigation system is provided. The medical navigation system includes a computing device having a processor coupled to a memory, a wireless communication component and a display for displaying an image. The medical navigation system further includes a sensor module attached to a medical device. The sensor module includes a housing for housing components of the sensor module and for attaching to the medical device, a processor housed in the housing, a memory coupled to the processor, a wireless communication component coupled to the processor, a battery coupled to the processor, and a sensor coupled to the processor. The sensor generates a signal to be transmitted wirelessly via the sensor module wireless communication component and receivable by the computing device wireless communication component, the signal representing movement of the medical device.
