  • Publication number: 20190223964
    Abstract: The system for camera control in robotic and laparoscopic surgery (100) includes a head tracking system (130) for tracking movements of an operator's head during laparoscopic surgery, a robotic laparoscope holder (110) operatively engaged to a laparoscope (200), an interface workstation (120) having a processor (540) and inputs connecting the sensor signal and the servo control system (515) signals to the processor (540), and a clutch switch (180) connected to the processor (540) for activating and inactivating the interface workstation (120). The head tracking system (130) includes at least one optical marker (415) to be worn on the operator's head and an optical tracker (410) for detecting movement of the at least one optical marker (415) and transmitting a corresponding sensor signal. The laparoscope includes an articulating distal portion (214), a tip (216), and a camera (150) disposed at the tip (150).

  • Patent number: 9855103
    Abstract: Provided herein are systems, modules and methods of using the same for in-situ real time imaging guidance of a robot during a surgical procedure. The systems comprise a plurality of modules that intraoperatively link an imaging modality, particularly a magnetic resonance imaging modality, a medical robot and an operator thereof via a plurality of interfaces. The modules are configured to operate in at least one computer having a memory, a processor and a network connection to enable instructions to generally control the imaging modality, track the robot, track a tissue of interest in an area of procedure, process data acquire from imaging modality and the robot and visualize the area and robot. Also provided are non-transitory computer-readable data storage medium storing computer-executable instructions comprising the modules and a computer program produce tangibly embodied in the storage medium.
