摘要:
Surgical robots and other telepresence systems have enhanced grip actuation for manipulating tissues and objects with small sizes. A master/slave system is used in which an error signal or gain is artificially altered when grip members are near a closed configuration.
摘要:
Enhanced telepresence and telesurgery systems automatically update coordinate transformations so as to retain alignment between movement of an input device and movement of an end effector as displayed adjacent the input device. A processor maps a controller workspace with an end effector workspace, and effects movement of the end effector in response to the movement of the input device. This allows the use of kinematically dissimilar master and slave linkages. Gripping an input member near a gimbal point and appropriate input member to end effector mapping points enhance the operator's control. Dexterity is enhanced by accurately tracking orientational and/or angles of movement, even if linear movement distances of the end effector do not correspond to those of the input device.

摘要:
Telerobotic, telesurgical, and/or surgical robotic devices, systems, and methods employ surgical robotic linkages that may have more degrees of freedom than an associated surgical end effector n space. A processor can calculate a tool motion that includes pivoting of the tool about an aperture site. Linkages movable along a range of configurations for a given end effector position may be driven toward configurations which inhibit collisions. Refined robotic linkages and method for their use are also provided.
摘要:
The invention provides robotic surgical systems which allow selectable independent repositioning of an input handle of a master controller and/or a surgical end effector without corresponding movement of the other. In some embodiments, independent repositioning is limited to translational degrees of freedom. In other embodiments, the system provides an input device adjacent a manipulator supporting the surgical instrument so that an assistant can reposition the instrument at the patient's side.
