  • SURGICAL SYSTEM PROVIDING HANDS-FREE CONTROL OF A SURGICAL TOOL
    Publication number: 20170042730
    Abstract: A surgical system provides hands-free control of at least one surgical tool includes a robot having a tool connector, a smart tool attached to the tool connector of the robot, and a feedback control system configured to communicate with the smart tool to provide feedback control of the robot. The smart tool includes a tool that has a tool shaft having a distal end and a proximal end, a strain sensor arranged at a first position along the tool shaft, at least one of a second strain sensor or a torque-force sensor arranged at a second position along the tool shaft, the second position being more towards the proximal end of the tool shaft than the first position, and a signal processor configured to communicate with the strain sensor and the at least one of the second strain sensor or the torque-force sensor to receive detection signals therefrom.
    Type: Application

  • Multi-force sensing surgical instrument and method of use for robotic surgical systems
    Patent number: 9549781
    Abstract: A multi-force sensing instrument includes a tool that has a tool shaft having a distal end and a proximal end, a strain sensor arranged at a first position along the tool shaft, at least one of a second strain sensor or a torque-force sensor arranged at a second position along the tool shaft, the second position being more towards the proximal end of the tool shaft than the first position, and a signal processor configured to communicate with the strain sensor and the at least one of the second strain sensor or the torque-force sensor to receive detection signals therefrom. The signal processor is configured to process the signals to determine a magnitude and position of a lateral component of a force applied to the tool shaft when the position of the applied force is between the first and second positions.
