  • Patent number: 11801103
    Abstract: A surgical system includes: a tool manipulator having a tool manipulator arm and a surgical tool; a console having a handling tool configured to receive a tool movement input of a surgeon for the surgical tool, the console being configured to transmit a tool movement command generated based on the tool movement input, the tool movement input including a translation amount and a rotation amount for the surgical tool; and a controller. The controller is configured to calculate an actual translation amount by multiplying the translation amount by a predetermined translation scale factor and move the surgical tool in accordance with the actual translation amount, and to calculate an actual rotation amount by multiplying the rotation amount by a predetermined rotation scale factor and move the surgical tool in accordance with the actual rotation amount. The translation scale factor and the rotation scale factor are different values.

  • Patent number: 11517384
    Abstract: A surgical system includes a surgical assist robot including a robot main body and a slave controller, and a console. The robot main body has an entry guide, an entry guide support device, and at least one manipulator having an end effector provided at a distal end. The entry guide includes an inner cylinder, an outer cylinder into which the inner cylinder is inserted in an insertion axial direction, and a guide advancing device that displaces the inner cylinder in the insertion axial direction with respect to the outer cylinder. While a position and a posture of the end effector that has advanced from the entry guide are maintained, the inner cylinder is caused to advance toward the end effector within a predetermined movable range along the insertion axial direction with respect to the outer cylinder.
