Abstract: A medical manipulator system includes: a medical manipulator having a movable portion; and a drive device to which the medical manipulator is detachably connected. The medical manipulator includes a driven portion to which a driving force for driving the movable portion is input. The drive device includes: a drive portion that is attached to the driven portion when the medical manipulator is connected and drives the driven portion; and a controller that controls the drive portion. The number of the drive portions is greater than the number of the driven portions. The drive device is capable of simultaneously connecting a first manipulator and a second manipulator that are the medical manipulators. All of the driven portions of the first manipulator and the second manipulator are attachable to the drive device.

Abstract: A medical manipulator system includes: a medical manipulator having a bending portion; a drive device connected to the medical manipulator and bending the bending portion; and a controller into which a manipulation input for bending the bending portion is input. The drive device is configured to determine a bending direction in which the bending portion is bent based on a first part of the manipulation input, and determine an amount of bending drive based on an entire input from a start to an end of the manipulation input.

Abstract: A medical manipulator system includes: a medical manipulator including an insertion portion having a bending portion and a wire connected to the bending portion; a drive device connected to the medical manipulator and driving the wire to bend the bending portion, wherein the drive device pulls the wire at a higher speed when the wire is slack than when the wire is not slack, and determines whether the wire is slack or not based on a comparison between a threshold tension estimated from a shape of the insertion portion and a tension of the wire.

Abstract: A medical manipulator system includes a medical manipulator having an insertion portion to be intracorporeally inserted, a drive device to which the medical manipulator is detachably connected, and a controller which is communicatively connected to the drive device and to which a manipulation input for driving the medical manipulator is input. The controller has a groove engaged with a part of the medical manipulator. The medical manipulator has a connection portion and an extracorporeal flexible portion. The connection portion rotatably connects the insertion portion and the extracorporeal flexible portion around a rotation axis extending in a longitudinal direction of the medical manipulator. The connection portion has a fitting portion fitted with the groove of the controller.
