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.

Overtube system and operation method of the same

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.

Medical manipulator system and image display method therefor

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.

Medical manipulator system and operating method thereof

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.
