  • Patent number: 11419687
    Abstract: A computer-assisted device includes an articulated arm configured to support an end effector and a control unit configured to, when coupled to the articulated arm and a table: determine a virtual coordinate frame before a first joint of the articulated arm is set to a floating mode, configure the first joint to the floating mode, detect movement of the first joint, determine a movement of the table, and drive a second joint of the articulated arm based on the movement of the first joint and the movement of the table. In some embodiments, the virtual coordinate frame is based on a pose of an imaging device and/or is detached from the imaging device. In some embodiments, the control unit is further configured to maintain the virtual coordinate frame in fixed relationship to a top of the table based on motion data received from the table.

  • Patent number: 10993772
    Abstract: A system and method for integrated table motion includes a device. The device includes an articulated arm having joints and a distal portion distal to the joints and a control unit. To support integrated motion with a separate table, the control unit is configured to receive a table movement request from the table, determine whether allowing the table movement request would result in a first joint of the joints being at a range of motion limit, allow the table to perform the table movement request based on determining that allowing the table to perform the table movement request would not result in the first joint being at the range of motion limit, track movement of the table due to performing the table movement request, and maintain, using the joints and based on the tracked movement, a position and/or an orientation of the distal portion relative to the table.

  • Patent number: 10617479
    Abstract: A computer-assisted medical device includes a first articulated arm, the first articulated arm having an end effector, a first joint set, a second joint set and a control unit. The control unit configures one or more joints in the first joint set to a floating mode, detects movement of the first joint set caused by a movement of the surgical table, drives the second joint set based on the movement of the surgical table, receives an instrument motion command to move the end effector while the surgical table is moving, and moves the end effector based on the instrument motion command. In some embodiments, the instrument motion command is relative to an imaging coordinate frame. In some embodiments, the imaging coordinate frame is based on a pose of an imaging device saved prior to the movement of the surgical table.

  • Patent number: 10226306
    Abstract: A system and method for an integrated surgical table includes a medical device including an articulated arm having one or more first and second joints and a control unit. The articulated arm has at least a cannula, an endoscope, or an instrument mounted distal to the first and second joints, which is inserted into a patient at a body opening. The control unit unlocks the first joints, receives a surgical table movement request, determines whether the surgical table movement request should be granted, allows the surgical table to perform the requested movement based on the determining, uses the first joints to allow the articulated arm to track movement of the body opening based on forces applied by a body wall at the body opening, and compensates for changes in a pose of the cannula, endoscope, or instrument due to the tracked movement by performing compensating motions in the second joints.
