Abstract:
Active and semi-active damping of systems include a first link supported by a base, a second link, a damper coupling the first link to the second link, the damper having a variable damping coefficient, and a processor. The processor is configured to predict an acceleration or a vibration of the second link expected to result from a commanded movement of the second link and adjust the variable damping coefficient of the damper based on the predicted acceleration or the predicted vibration to reduce vibration in the second link.

Abstract:
A surgical system includes methods and systems for damping vibrations. The surgical system can include one or several moveable set-up linkages. A passive, active, or semi-active damper can be connected with one or several of the set-up linkages. The damper can mitigate a vibration arising in one of the set-up linkages and the damper can prevent a vibration arising in one of the linkages from affecting another of the set-up linkages. The active and semi-active dampers can be controlled with a feedback or a feed-forward model. In some embodiments, the system includes a first link supported by a base, a second link, a damper having a variable portion coupling the first link to the second link, and a processor. The processor is configured to detect a movement or a vibration of the second link and adjust the variable portion of the damper based on the detected movement or vibration.
Abstract:
A device to regulate tension of an actuation element for actuating movement of a surgical instrument includes an elastically deformable body configured to be coupled to the actuation element. The deformable body is configured to elastically deform in response to a state of slack occurring in the actuation element. As slack occurs in the actuation element, the deformable body is configured to divert a path of the actuation element to accommodate the slack so the path of the actuation element differs from an axis the actuation element follows prior to the actuation element developing slack. A force transmission mechanism for a teleoperated surgical instrument includes a chassis, an actuation input mechanism, an actuation element, and a tension regulator coupled to the actuation element to compensate for slack of the actuation element.

A medical robotic system having non-ideal actuator-to-joint linkage characteristics, includes a control system including a proximal control loop with actuator sensor feedback to control dynamic response of an actuator coupled to a distal joint which in turn, is coupled to an end effector to provide a degree of freedom movement of the end effector, a distal control loop with distal joint sensor feedback and feedforward to the actuator to ensure steady-state convergence of the distal joint position, and an end effector control loop with end-point sensor feedback to control the end effector position to reach a commanded end effector position.
Abstract:
Teleoperated control includes commanding, in response to a first input to move a tool while an imaging device is mounted to a first manipulator and a tool is mounted to a second manipulator, actuator(s) of the second manipulator to move the tool with a first motion relative to a first reference frame that corresponds with a first movement of an input device relative to a display, the first reference frame defined based on the imaging device mounted to the first manipulator; and commanding, in response to receiving a second input to move the tool while the imaging device is mounted to the third manipulator, the actuator(s) to move the tool with a second motion relative to a second reference frame that corresponds with a second movement of the input device relative to the display, the second reference frame defined based on the imaging device being mounted to the third manipulator.
Abstract:
A cannula mount for a surgical system includes pivotable clamping arm with a first feature configured to engage a second feature of the cannula positioned in the cannula mount. The clamping arm comprises a cam follower surface. The cannula mount further comprises a latch member movable between at least a first position and a second position, and the latch member comprises a cam surface. On the condition that the latch member is in the first position, the cam surface engages the cam follower surface of the clamping arm to actuate the clamping arm to a closed position in which the first feature engages the second feature. On the condition the cam member is in the second position, the clamping arm is free to move to an open position in which the first feature does not engage the second feature. Devices and methods relate to cannula mounts.
Abstract:
Methods, apparatus, and systems for controlling a telesurgical system are disclosed. In accordance with a method, a first tool connected to a first manipulator of the system, and a second tool connected to a second manipulator of the system, are controlled. A swap of the tools such that the first tool is connected to the second manipulator and the second tool is connected to the first manipulator is then detected. The first tool connected to the second manipulator and the second tool connected to the first manipulator are then controlled.
