  • Publication number: 20160270773
    Abstract: Minimaily invasive surgical retractors and methods of using the retractors are provided. This retractor may be introduced through a sealed port, controlled by a robotic system, have full articulation, and need not require assembly within the patient's body. As a result, fully endoscopic mitral valve surgery may be performed.
    Type: Application

  • Patent number: 8540748
    Abstract: A link is positioned to pivot at the distal end of a surgical instrument shaft. The link includes a pulley portion. A first control cable that pivots the link in one direction extends out of the surgical instrument shaft and crosses the width of the instrument in a first crossing direction. The first control cable is then routed around the pulley portion of the link in a first circumferential direction. Similarly, a second control cable that pivots the link in the opposite direction extends out of the surgical instrument shaft and crosses the width of the instrument in a second crossing direction. The second control cable is then routed around the pulley portion of the link in a second circumferential direction that is opposite the first circumferential direction.

  • Patent number: 8473031
    Abstract: A medical robotic system has functionality to determine and display information of a distance indicated by movement of one or more tools being robotically manipulated by an operator. The distance is determined using sensed robotic manipulation of the one or more tools. Information of the distance is displayed on the monitor so as to be visually associated with the movement and/or positions of the tools, such as a virtual tape measure that extends along with or between images of the one or more tools on the monitor or as a virtual ruler with the distance being indicated by a pointer. Alternatively, information of the distance may simply be indicated on a digital read-out shown on the monitor that is displayed and continually updated with the movement of the one or more tools.

  • Publication number: 20120209291
    Abstract: A surgical accessory clamp, method of use, and a robotic surgical system including the clamp are disclosed. A surgical accessory may be attached and removed from a manipulator arm during a surgical procedure without requiring the use of an intermediate sterile accessory clamp, thus removing the need for a detachable accessory mount or adaptor that needs cleaning and sterilization and allowing for greater efficiency and cost-effectiveness. The present invention further allows for easy removal and attachment of instruments, tools, or accessories to the robotic surgical system without breach of sterility.

The accessory clamp further allows for easy removal and attachment of instruments, tools, or accessories to the robotic surgical system without breach of sterility. In one embodiment, an accessory clamp includes a base for coupling to a distal end of a manipulator arm; two clamp jaws adapted to receive a surgical accessory, each of the clamp jaws rotatably coupled to the base and configured to pivot relative to one another; a sterile drape portion over the two clamp jaws; and a lever portion capable of actuating the two clamp jaws into an open position or a closed position.
