Abstract: A medical manipulator system including: a placement table on which a patient is placed; at least one manipulator configured to support a treatment tool which is configured to treat the patient, the manipulator configured to adjust a position and an orientation of the treatment tool; a base portion configured to support the manipulator; a sensor configured to detect objects which are present in a predetermined area including the manipulator and the placement table; and a controller including at least one processor, wherein the processor is configured to: calculate degrees of proximity between the objects detected by the sensor and the manipulator, and generate, in case that the calculated degrees of proximity exceed a predetermined threshold, a control signal for preventing interference between the objects and the manipulator.

Abstract: A medical manipulator system includes: an endoscope; a first manipulator equipped with a first treatment tool at a distal end thereof; a second manipulator equipped with a second treatment tool at a distal end thereof; a display for a user to view; and a controller configured to generate an image to be displayed on the display. The controller is configured to: acquire a first image taken by the endoscope, the first image contains the first treatment tool; and in response to determining that the second treatment tool does not exist in the first image: calculate a relative distance and a relative direction between the first treatment tool and the second treatment tool; generate a second image showing the relative distance and the relative direction between the first treatment tool and the second treatment tool; and send the first image and the second image to the display.

Abstract: An overtube system configured to introduce an endoscope into a body, includes a tubular main body formed to be insertable for the endoscope; a balloon attached to an cuter circumferential surface of the main body; a driver configured to inflate and deflate the balloon; and a controller configured to control the driver, wherein the controller is configured to: generate an operation signal for the driver, calculate a relative rotation state between the main body and the endoscope around a longitudinal axis of the endoscope, generate a correction operation signal by correcting the operation signal according to the relative rotation state, and transmit the correction operation signal to the driver to operate the driver.

Abstract: A manipulator system of the present invention includes a manipulator driven by a motor, an operating part for generating an operation input for operating the manipulator, and a controller for controlling the motor. The controller controls for receiving a first current and a first voltage of the motor, for calculating a first resistance value of the motor on the basis of the first current and the first voltage, for controlling the motor to rotate thereof under a predetermined angle, for receiving a second current and a second voltage of the motor after rotating the motor, for calculating a second resistance value of the motor based on the second current and the second voltage, for adopting the larger one of the first resistance value and the second resistance value as a calculated resistance value, and for controlling the motor based on the operation input and the calculated resistance value.

Abstract: The method for controlling a medical manipulator is a method for controlling a medical manipulator which drives a driven part by rotating a motor in accordance with an operation input from an operation part. The method includes: a first step of performing a trial driving when the operation input occurs, and evaluating changes in winding resistance based on a temperature rise of the motor, and setting a driving condition of the motor based on the evaluated changes winding resistance; and a second step of performing driving which corresponds to the operation input based on the driving condition of the motor set in the first step.
