摘要： Methods and devices for identifying and defining a safety zone for restricting movement of a robotic arm in an operating room during a medical procedure are disclosed. The disclosed method utilizes medical navigation system, which receives an initiation input indicating initiation of defining of the safety zone. In response to receiving the initiation input, the system tracks an instrument and determines the location of the tracked instrument relative to a reference point. The system detects changes in the location of the tracked instrument until a termination input is received at the medical navigation system. The termination input indicates the termination of the defining of the safety zone. The system stores, in memory, change data indicative of the changes in the location of the tracked instrument. The data identifies the safety zone relative to the reference point.

摘要： The application as disclosed herein describes systems and methods for performing patient registration using a surgical navigation system. This application attempts to provide for improvements upon existing systems through the addition of refinement steps used to increase the accuracy of registration and streamline said process. In some cases the improvements generally involve the manipulation of spatial data in an iterative manner.

摘要： A system for adjusting an operating state of a medical electronic device is described. In an aspect, the system includes an optical tracking system configured to detect three or more tracking markers. The system also includes a processor coupled with the optical tracking system. The processor is programmed with instructions which, when executed, configure the processor to: configure an input command by assigning at least one operating state of the medical electronic device to a particular state of at least one of the tracking markers; after receiving a priming command, identify a present state of the tracking markers based on data from the optical tracking system; compare the present state with the particular state assigned to the operating state; and based on the comparison, determine that an input command has been received and adjust the operating state of the medical electronic device to the assigned operating state.

摘要： A training system for training a trainee to perform a surgical procedure on an anatomical region. The system includes a physical model of the anatomical region, a physical training instrument, a tracking system configured to track the location and orientation of the physical training instrument relative to the physical model, a display device, and a computer system. The computer system receives from the tracking system information indicating the location and orientation of the physical training instrument and generates and displays an augmented physical model and the physical training instrument. The display is updated based as the trainee manipulates the physical training instrument. After the trainee has completed the surgical procedure, the computer calculates a score based on the performance of the trainee. The score is a measure of the accuracy of the surgical procedure performed by the trainee or the duration of the surgical procedure.

摘要： A fiducial marker to be tracked by a surgical navigation system. The fiducial marker is to be affixed to an object during a surgical procedure. The fiducial marker including a casing for attachment to the object; a light emitting component attached to the casing; a power source within the casing; a signal receiver to receive a signal from the surgical navigation system; and control logic to control the light emitting component in response to the signal from the surgical navigation system. The object to-be-tracked may include a plurality of the fiducial markers arranged in geometric pattern, and the markers may include a first active fiducial marker having a first light emitting component that emits light having a first spectral bandwidth, and a second active fiducial marker having a second light emitting component that emits light having a second spectral bandwidth different from the first spectral bandwidth.

摘要： A medical navigation system for displaying a three dimensional (3D) surface video of a target is provided. The medical navigation system comprises a 3D imaging device, a camera, a display, and a controller electrically coupled to the 3D imaging device, the camera, and the display. The controller has a processor coupled to a memory. The controller is configured to perform calibration of input devices; acquire 3D depth data of the target from a signal generated by the 3D imaging device; construct a 3D surface contour of the target based on the 3D depth data; acquire a video stream of the target from a signal generated by the camera; generate a 3D surface video based on the 3D surface contour and the video stream; and display the 3D surface video on the display.
