Abstract
A locating system for a surgical suite includes optical markers coupled to a medical device. A sensor is configured to obtain an initial position data of the optical markers. A laser device is configured to obtain subsequent position data of the optical markers. A controller receives the initial position data from the sensor and the subsequent position data from the laser device. The controller is configured to determine a position of the medical device within the surgical suite and recognize a type of the medical device in response to the optical markers.
Claims18
A locating system for a surgical suite, comprising:
- optical markers coupled to a medical device;
- a locating assembly configured to be coupled with a ceiling in said surgical suite, the locating assembly including:
- a time-of-flight sensor including a light source and an image sensor and configured to obtain initial position data of the optical markers and a distance between the medical device and the time-of-flight sensor;
- and
- a laser device including a laser light source and a detector, the laser device configured to emit light to obtain subsequent position data of each optical marker based on the initial position data, wherein the laser device is configured to utilize the initial position data to determine a direction to direct the light;
- and
- a controller configured to receive the initial position data from the time-of-flight sensor and the subsequent position data from the laser device, wherein the controller is configured to:
- determine a position and an orientation of the medical device within said surgical suite utilizing both the initial position data and the subsequent position data;
- and
- recognize a type of the medical device in response to the optical markers.
A method of adjusting a device within a surgical suite, comprising:
- detecting a type of a medical device within said surgical suite;
- determining whether the medical device is a fixed medical device or a movable medical device, the movable medical device having a feature for moving the movable medical device in at least one direction in response to a control signal;
- estimating a position of the movable medical device using a three-dimensional sensor and at least one optical marker coupled to the medical device;
- confirming the position of the movable medical device using a laser device and the at least one optical marker based on the position estimated by the three-dimensional sensor;
- determining an orientation of the movable medical device using the laser device and the at least one optical marker;
- determining at least one of a movement path and an adjustment path for the movable medical device prior to movement of the movable medical device;
- and
- moving the movable medical device via the feature within said surgical suite in response to a confirmed position and orientation of the medical device.
A locating system for a surgical suite, comprising:
- a plurality of optical markers coupled to a medical device;
- a three-dimensional sensor including a light source and an image sensor and configured to obtain initial position data of the plurality of optical markers utilizing emitted light;
- a laser device including a laser light source and a detector, the laser device configured to emit light to obtain subsequent position data of the plurality of optical markers, wherein the laser device is configured to utilize the initial position data to determine a direction to emit the light to obtain the subsequent position data;
- and
- a controller configured to receive the initial position data from the sensor and the subsequent position data from the laser device, the controller configured to:
- determine an estimated position of the medical device within said surgical suite based on the initial position data from the three-dimensional sensor;
- adjust the laser device in response to the initial position data to emit the light toward the estimated position;
- confirm a position of the medical device within said surgical suite based on the subsequent position data from the laser device;
- and
- determine at least one of a movement path and an adjustment path for the medical device prior to movement of the medical device;
- and
- an adjustment feature coupled to the medical device and communicatively coupled to the controller, wherein the adjustment feature is configured to adjust the medical device along the at least one of the movement path and the adjustment path in response to a control signal from the controller.
