  • Publication number: 20180067548
    Abstract: The present invention describes a hands-free system for controlling the movement of a cursor on one or more display devices. A tracking device including a traceable marker and one or more accelerometers and gyroscopes are used to track position and acceleration of the marker relative to a target of interest. A processing means processes the motion signals from the tracking device to determine the location of the cursor on the operator's monitor, which may also be displayed on more monitors. The tracking device is worn by the operator, optimally on the operator's head. The operator's head movements determine movement of the cursor.

  • Publication number: 20110046637
    Abstract: The present invention provides a sensorized medical instrument that is suitable for application to, and training and skills assessment for, a variety of therapeutic, diagnostic, surgical and medical procedures. It is comprised of a sterilizable sensorized instrument capable of measuring forces in five degrees of freedom and tip position in six degrees of freedom. The instrument can be used to perform a variety of tasks through the integration of interchangeable instrument tips and handles. The system is capable of providing feedback to the user regarding critical forces/torques acting on the tissue, position and orientation of the instrument and its tip near critical areas within the body, or user performance during training and skills evaluation.

  • Patent number: 6368332
    Abstract: A system for performing coronary artery bypass grafting surgery on the beating heart senses the movement of the surgical area of the heart to be worked on and moves a support with a controlled motion follows the motion of the surgical area on the heart surface in real time. To provide a steady image of the workspace a vision system can be attached to the support. This approach can be used for open-heart surgery as well as other less invasive procedures like minimally invasive direct coronary artery bypass (MIDCAB) or thoracoscopic surgery.
