  • Publication number: 20210153964
    Abstract: A teleoperative system includes an input device and a controller. The controller is configured to receive input associated with movement of the input device, determine a commanded pose of an instrument coupled to the teleoperative system based on the received input, determine a first preferred pose of the instrument based on at least one parameter selected from a group consisting of: a type of the instrument and an operating mode of the instrument, determine a first feedback force command based on a difference between the commanded pose and the first preferred pose, and actuate the input device based on the first feedback force command.

  • Patent number: 10959798
    Abstract: A medical robotic system includes an entry guide with articulated instruments extending out of its distal end. A controller is configured to command manipulation an articulated instrument in response to operator manipulation of an associated input device while generating a force command to the input device that nudges the operator to command the instrument to a preferred pose. When a transition is to occur between first and second preferred poses, one is phased in while the other is phased out. Virtual barriers may be imposed to prevent the articulated instrument from being commanded to an undesirable pose.

  • Patent number: 10835320
    Abstract: A surgical system comprises an instrument and a teleoperated instrument operation system. The instrument comprises a drive member having an end effector coupled to the distal end and a ratchet assembly coupled to the proximal end. The ratchet assembly includes a pin, a gear, and a spring- loaded button. A lever is coupled to and configured to pivot relative to the ratchet assembly to engage the spring-loaded button to disengage the pin from the gear. The lever in a first position places the ratchet assembly in a gripping position in which the end effector grips a surgical accessory. The lever in a second position places the ratchet assembly in a release position in which the end effector releases the surgical accessory. The lever is movable while compressing the spring-loaded button. The teleoperated instrument operation system comprises a capture mechanism configured to move the lever between the first and second positions.

  • Publication number: 20200322526
    Abstract: An imaging system comprises an image capturing device, a viewer, a control element, and a processor. The control element controls or adjusts an image characteristic of one of the image capturing device and the viewer. The processor is programmed to determine a depth value relative to the image capturing device, determine a desirable adjustment to the control element by using the determined depth value, and control adjustment of the control element to assist manual adjustment of the control element to the desirable adjustment. The processor may also be programmed to determine whether the adjustment of the control element is to be automatically or manually adjusted and control adjustment of the control element automatically to the desirable adjustment if the control element is to be automatically adjusted.

  • Patent number: 10772689
    Abstract: To perform a tool exchange in a medical robotic system, tool is retracted back into an entry guide from a deployed position and pose so that an assistant in the operating room may replace it with a different tool. While the tool is being retracted back towards the entry guide by user action, its configuration is changed to an entry pose while avoiding collisions with other objects so that it may fit in the entry guide. After the tool exchange is completed, a new tool is inserted in the entry guide and extended out of the guide by user action to the original position of the old tool prior to its retraction into the entry guide while the tool's controller assists the user by reconfiguring the new tool so as to resemble the original deployed pose of the old tool prior to its retraction into the entry guide.

  • Publication number: 20200282570
    Abstract: A surgical system uses a single entry port in a wide variety of surgeries. To insert multiple surgical instruments into a patient through a single entry port requires that the shaft of at least one of the surgical instruments be bent between the base of the surgical instrument and the point where the shaft contacts a channel in an entry guide. Each surgical instrument is positioned by an instrument manipulator positioning system so that when the shaft is inserted in a channel of the entry guide, any bending of the shaft does not damage the surgical instrument and does not inhibit proper operation of the surgical instrument.

  • Patent number: 10543050
    Abstract: In a minimally invasive surgical system, a hand tracking system tracks a location of a sensor element mounted on part of a human hand. A system control parameter is generated based on the location of the part of the human hand. Operation of the minimally invasive surgical system is controlled using the system control parameter. Thus, the minimally invasive surgical system includes a hand tracking system. The hand tracking system tracks a location of part of a human hand. A controller coupled to the hand tracking system converts the location to a system control parameter, and injects into the minimally invasive surgical system a command based on the system control parameter.
