Abstract
An illumination system for monitoring and illuminating an operating region includes at least one light assembly including at least one illumination source configured to selectively direct a light emission in a portion of the operating region. At least one imager is configured to capture image data in a field of view in the operating region. A controller is in communication with the light assembly and the imager. The controller is configured to process image data captured in the field of view and identify a plurality of objects detected in the image data based on an object library. Track a location of each of the plurality of objects and store the location of each of the objects.
Core Innovation
The invention relates to an illumination system for monitoring and illuminating an operating region. The system includes at least one light assembly with at least one illumination source configured to selectively direct a light emission in a portion of the operating region, and at least one imager configured to capture image data in a field of view in the operating region. A controller processes the image data, identifies a plurality of objects as a plurality of medical implements detected in the image data based on an object library, and accesses object information for use in the operating region.
The controller tracks a location of each of the plurality of objects moving about the operating region and tracks a path of one or more of the objects moving about the operating region. The controller records the path of the one or more objects over time and records movement statistics of the one or more objects identifying the distance traveled. The controller further supports object-related workflow elements by using the object information and by monitoring movement behavior of objects while they are moving about the operating region.
The invention further integrates balance determination and unexpected-object illumination. The controller completes a balance determination of each of the plurality of objects over a period of time, maintains an accounting of the plurality of objects, and assigns an accounting classification for each object, where the accounting classification identifies a status upon introduction into the operating region or as a final location, including disposal, storage, and an implanted location. The controller identifies an unexpected object in the library that is not identified as preapproved based on object data, and illuminates the unexpected object using at least one illumination source comprising a plurality of illumination sources configured to illuminate objects in the operating region with first color and second color emissions.
Claims Coverage
The partial content provides three independent claims. Across these independent claims, the core inventive coverage includes selective directed illumination synchronized with imager-based detection using an object library, object identification and tracking with recorded movement statistics, balance determination with accounting classifications by object status, and unexpected-object detection with color-differentiated illumination directed to an unexpected object.
Selective directed illumination with imager-based object monitoring
An illumination system for monitoring and illuminating an operating region including at least one light assembly with an illumination source configured to selectively direct a light emission in a portion of the operating region, and at least one imager configured to capture image data in a field of view in the operating region, with a controller in communication with the light assembly and the imager to process the image data.
Object library identification and tracking of medical implements
The controller identifies a plurality of objects as a plurality of medical implements detected in the image data based on an object library, accesses object information identifying the medical implements for use in the operating region, and tracks a location of each of the plurality of objects moving about the operating region.
Path recording and movement statistics
The controller tracks a path of one or more of the objects moving about the operating region, records the path of the one or more objects over time, and records movement statistics of the one or more objects identifying the distance traveled.
Balance determination with accounting classifications over time
The controller identifies a plurality of objects detected in the image data based on an object library, accesses object information for the plurality of objects, and completes a balance determination of each object over a period of time while maintaining an accounting of the plurality of objects and assigning an accounting classification for each of the objects.
Accounting classification for disposal, storage, and implanted location
The accounting classification identifies a status of the plurality of objects upon introduction into the operating region or as a final location, and the accounting classifications comprise a disposal, a storage, and an implanted location.
Unexpected object identification relative to preapproved associated objects
The controller identifies a plurality of objects detected in the image data based on an object library and accesses object information for the plurality of objects, where the object data identifies the plurality of objects as associated objects preapproved for use in the operating region, compares the identified objects to the associated objects identified in the object information, and based on the comparison identifies an unexpected object in the library that is not identified as preapproved based on the object data.
Color-differentiated illumination of unexpected object
In response to the identification of the unexpected object, illuminate the unexpected object with the at least one light emission, wherein the at least one illumination source comprises a plurality of illumination sources configured to illuminate objects in the operating region in a first emission having first color and second emission having a second color, where the first emission is projected into the operating region and illuminates a target area and the second emission is directed to and illuminates the unexpected object.
Taken together, the independent claims cover an operating-region illumination system that uses an imager to capture image data, identifies multiple objects based on an object library, tracks locations and records movement paths and movement statistics, performs balance determination with accounting classifications for object status including disposal, storage, and implanted location, and detects unexpected objects not preapproved in the library and illuminates them using first and second color emissions.
Stated Advantages
Records each object's path over time and movement statistics identifying the distance traveled.
Maintains an accounting of objects and assigns an accounting classification identifying a status upon introduction or as a final location.
Illuminates an unexpected object in response to identification of the unexpected object not identified as preapproved.
