A medical manipulator system including: a treatment tool unit including an arm portion having an arm with a joint and an end effector attached to the arm; an overtube having a lumen through which the treatment tool unit is inserted; a drive source configured to generate a drive force for driving the joint; a controller configured to generate an operation signal for operating the drive source; and a detector configured to detect friction generated between an inner surface of the lumen and the treatment tool unit. The controller calculates a correction amount for adjusting the operation signal based on the detected friction.

Medical manipulator system and method for operating medical manipulator system

A medical system includes: a medical instrument; at least one arm including at least one joint and motor that drive the at least one joint, the at least one arm including an attachment portion for detachably attaching the medical instrument to a distal end; a first input device located remote from the arm and configured to perform an operation input for operating the medical instrument and the at least one arm; a second input device provided at a distal end of the arm and configured to perform an operation input for operating the medical instrument and the at least one arm; and a processor that controls the at least one arm and the medical instrument based on an operation input from the first or second input device. The medical system enables switching in order to selectively accept an operation input from the first or second input device.

Medical system

A manipulator including an elongated shaft, a distal-end treatment section disposed at a distal end of the shaft, a distal-end articulated section having a bendable joint and a rotatable joint, and a proximal-end operating section disposed at a proximal end side of the shaft, wherein the bendable joint has an axis intersecting a longitudinal axis of the shaft, the rotatable joint has an axis that intersects the axis of the bendable joint and that is substantially aligned with a central axis of the distal-end treatment section, the proximal-end operating section includes a first operating section gripped by one hand and causing the bendable joint to move about the axis intersecting the longitudinal axis of the shaft, and also includes a second operating section provided in the first operating section and causing the rotatable joint to move.
