  • Publication number: 20190053872
    Abstract: The present disclosure is directed to systems and methods for removing an occluding object from a surgical image. An image capture device is inserted into a patient and captures an initial image of a surgical site inside the patient during a surgical procedure. A controller receives the image and determines that the occluding object is present in the initial image. The controller executes a removal algorithm that includes controlling the image capture device to perform a plurality of movements, controlling the image capture device to capture a plurality of images, wherein each image among the plurality of images corresponds to a movement among the plurality of movements, and applying an image filter to combine the initial image and the plurality of images and generate a processed image where the occluding object is removed from the processed image.

  • Publication number: 20180310811
    Abstract: The present disclosure is directed to an augmented reality surgical system. The system includes an endoscope that captures an image of the region of interest of a patient and an ECG device that records an ECG of the patient. A controller receives the image and applies at least one image processing filter to the image. The image processing filter includes a decomposition filter that decomposes the image into frequency bands. A temporal filter is applied to the frequency bands to generate temporally filtered bands. An adder adds each band frequency band to a corresponding temporally filtered band to generate augmented bands. A reconstruction filter generates an augmented image by collapsing the augmented bands. The controller also receives the ECG and processes the augmented image with the ECG to generate an ECG filtered augmented image. A display displays the ECG filtered augmented image to a user.

  • Publication number: 20180021058
    Abstract: A robotic surgical system includes an access port having a plurality of sensors incorporated therein and a surgical instrument having an end effector for use with, and connection to a robot arm. The sensors measure a loading parameter between tissue and the access port when the shaft is inserted through the access port. The sensors wirelessly transmit signals indicative of the loading parameter to a processing unit. The estimated loads at the tip of the end effector of the surgical instrument are provided in real-time to a haptic feedback interface for communicating haptic feedback to a user. The haptic feedback increases or decreases in intensity in response to a specific event, occurrence, or operational characteristic related to the estimated loads.

  • Patent number: 9607528
    Abstract: A surgery simulator includes a physical surrogate surgical interface that represents an interface between a user and a simulated patient in a simulated surgical scenario that involves manipulation of both simulated hard and soft tissue. Sensor(s) sense the user's manipulation of the surrogate surgical interface. A surgical simulation generator generates a real time 3D surgical simulation of the surgical scenario based on the manipulation sensed by the sensor(s). The real time 3D surgical simulation comprises real time simulation state data. The surgical simulation generator renders the real time simulation state data into a real time computer graphics generated video representation of the surgical simulation and provides the real time video representation to a display for real time viewing by the user. The surgical simulation generator simulates effects of the manipulation on both simulated hard tissue and simulated soft tissue of the simulated patient.

  • Patent number: 9142144
    Abstract: A simulator trains for hemorrhage control using hemostatic agents, tourniquets, and/or other hemorrhage control techniques in a simulator that works with a wide variety of existing human surrogates. The simulator merges a live video feed of the surrogate and trainee's hands (or objects interacting with the surrogate) with a computer-generated visual representation of the wound and hemorrhaging blood to provide an immersive display experience to the trainee without requiring different surrogates for different simulated wounds. The trainee may wear pulse-generating glove(s) that simulate the patient's pulse where the trainee's finger tip contacts the surrogate. A sensorized substrate (e.g., load sensors, haptic output generators) may automatically be moved between the trainee and the surrogate to sense interaction with the surrogate and provide haptic feedback. The substrate may replace the surrogate altogether. The simulator may alternatively simulate events and objects other than wounds and humans.

  • Patent number: 8915743
    Abstract: A system, method and device for simulating a medical procedure include a haptic mechanism controllable to provide feedback to a user manipulating a medical device. In an embodiment, a pair of three degree of freedom haptic devices are coupled to provide six degree of freedom measurement and force/moment feedback to the user. The six degree of freedom haptic device may be configured to provide different resolutions for different degrees of freedom, depending on simulation requirements. In an embodiment, a load cell is used to provide higher resolution in a dimension determined to be of greater criticality to realistic simulation.

  • Publication number: 20100178644
    Abstract: A simulator simulates interaction between a surgical tool and biological tissue, providing real time visual and/or haptic feedback. The simulator receives tool input device information representative of a user's movement of a physical tool. The simulator simulates, based on the tool input device information, an interaction between the simulated tool and simulated biological tissue. The simulator uses multiple computational threads, some of which provide their calculations to interrelated threads for use. The simulator displays a visual representation of the simulated interaction between the simulated tool and the simulated biological tissue and provides haptic feedback to the user. The threads may operate asynchronously and have different spatial and/or temporal resolutions. Threads may be selectively activated and deactivated. Threads may move their spatial coverage.
