Abstract: A medical robot system includes a memory and central processing unit that performs operations including receiving measurement signals of a gripping force, which is a force to grip an object by a surgical tool, and a dissecting force, which is a force to dissect the object by the surgical tool, generating image information for displaying information on the gripping force as a grip display mode and information on the dissecting force as a dissection display mode different from the grip display mode, based on the measurement signals, and outputting the image information to a display portion of a display that is configured to display the image information.

Abstract: A motive power transmission adapter includes a casing and at least one power transmission portion. The casing is disposed between a surgical tool and a power unit for driving the surgical tool. In addition, the casing includes a clean surface which is a surface facing the surgical tool disposed in a clean region and an unclean surface which is a surface facing the power unit disposed in an unclean region. At least one power transmission portion is movable relative to the casing and transmits a movement of the drive portion to the driven portion. In addition, at least one power transmission portion is disposed to be movable in a direction in which the clean surface and the unclean surface extend and is disposed between the drive portion and the driven portion in a direction intersecting a linear motion direction of the drive portion.

Abstract: A surgical robot system includes a surgical instrument including a shaft to be inserted through a trocar placed in a subject, an arm device that holds the surgical instrument and moves the surgical instrument with respect to the subject, a detector arranged at the arm device and configured to detect values of forces and torques acting on the surgical instrument; and a controller that calculates a value of a first external force that the surgical instrument receives from the trocar and a value of a second external force that is received from an object other than the trocar and that is abuttable on the surgical instrument, based on the values of forces and torques, and controls the arm device to move the surgical instrument, based on the value of the first external force and the value of the second external force.

Abstract: A medical robot system including a memory and a central processing unit that performs operations including receiving measurement signals of forces measured at two or more points on one or both of a surgical tool and a slave device that supports the surgical tool, generating image information for displaying information of the forces as images in association with the two or more points at which the forces are measured, based on the measurement signals, and outputting the image information that is generated to a display device that displays the image information in a second display region of the display device which is different from a first display region of the display device in which information on operation of the surgical tool is displayed.
