An endoscope includes: an insertion portion having a joint; a first wire and a second wire fixed on both sides of a central axis in a longitudinal direction of the joint at a distal end of the joint; a first wire sheath which is inserted through an internal path of the insertion portion and through which the first wire is inserted; and a second wire sheath which is inserted through the internal path of the insertion portion and through which the second wire is inserted, wherein the first wire sheath is bundled by a first fastener so as to be close to the second wire sheath, and the first wire sheath and the second wire sheath are bundled so as to be relatively advancing and retreating by the first fastener.

Endoscope having fastener for bundling wire sheaths in flexible portion and endoscope system

A processor of an operation supporting device acquires pre-operation data including position information of a feature portion of an inside of a body cavity of a subject, which is generated before an operation, and a procedure in the operation, which is planned before the operation, and acquires an endoscope image generated in the operation. The processor generates real-time data including real-time position information of the feature portion of the inside of the body cavity, based at least on the pre-operation data and the endoscope image, and generates an image to be displayed on the endoscope image in a superimposed manner, based on the real-time data. The processor recognizes a real-time scene based at least on the procedure planned before the operation and the real-time data.

Operation supporting device and method of operating operation supporting device

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 system and an operating method of a medical system are disclosed. The medical system can operate an endoscope to perform an operation task with respect to a site of interest of an organ of concern in response to input from an operator. The medical system includes a controller that can record a model of the organ of concern generated during preoperative planning, and record the names of a plurality of sites in the organ of concern, and corresponding regions or points in the model with respect to a first coordinate system. The controller receives the name of the site of interest, and the operation task; associates the first coordinate system of the model with a second coordinate system of a display space displayed by a display image; and operates the endoscope with respect to the site of interest on the basis of the operation task.

Medical system and medical system operating method

A manipulator including joint mechanisms each including: first and second members extending along a central axis; the second member disposed at a distal end of the first member and being swivelable relative to the first member about a swivel axis; a guide sheath extending near the central axis, a distal end of the guide sheath being fixed to the second member; a manipulation wire introduced toward the distal end of the guide sheath; and a pulley provided in the second member such that the manipulation wire is wound at least partially around the pulley to cause a distal end of the wire to change direction towards the first member, the pulley being rotatable about an axis parallel to the swivel axis; wherein the distal end of the manipulation wire is fixed to the first member near the inner surface of the through hole.

Joint mechanism, manipulator, and 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.
