Abstract:
A slave manipulator manipulates a medical device in response to operator manipulation of an input device through joint control systems. The stiffness and strength of the slave manipulator are adjustable according to criteria such as the mode of operation of the slave manipulator, the functional type of the medical device currently being held by the slave manipulator, and the current phase of a medical procedure being performed using the slave manipulator by changing corresponding parameters of the control system. For safety purposes, such changes are not made until it is determined that it can be done in a smooth manner without causing jerking of the medical device. Further, an excessive force warning may be provided to surgery staff when excessive forces are being commanded on the slave manipulator for more than a specified period of time.
Abstract:
A method of assigning an auxiliary input device to control a surgical instrument in a robotic surgical system can include automatically assigning an auxiliary input device to control an auxiliary function of a surgical instrument based on a position of the auxiliary input device and which of a user's hands is operating another input device operably coupled to control movement of the surgical instrument. A system for controlling a surgical instrument may include an input device of a surgical system that is operably coupled to generate and transmit an input control signal to control movement of a surgical instrument operably coupled to the surgical system. The system may further include an auxiliary input device, and a control system operably coupling the auxiliary input device to control an auxiliary function of the surgical instrument based on a position of the auxiliary input device and which of a user's hands is operating the input device.
Abstract:
Robotic and/or surgical devices, systems, and methods include kinematic linkage structures and associated control systems configured to facilitate preparation of the system for use. One or more kinematic linkage sub-systems may include joints that are actively driven, passive, or a mix of both. A set-up mode employs an intuitive user interface in which one or more joints are initially held static by a brake or joint drive system. The user may articulate the joint(s) by manually pushing against the linkage with a force, torque, or the like that exceeds a manual articulation threshold. Articulation of the moving joints is facilitated by modifying the signals transmitted to the brake or drive system. The system may sense completion of the reconfiguration from a velocity of the joint(s) falling below a threshold, optionally for a desired dwell time. The system may provide a detent-like manual articulation that is not limited to mechanically pre-defined detent joint configurations. Embodiments of the invention provide, and can be particularly well-suited for manual movement of a platform supporting a plurality of surgical manipulators in a robotic surgical system or the like without having to add additional input devices.
