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

The surgical tool () is including a main unit () including a case () and a hollow shaft () provided on the case (), a holder assembly () that holds a living tissue (T) in the body cavity, a connector () that connects the main unit () inserted through the shaft () to the holder assembly (), an operating unit () that is provided on the main unit () to allow the connector () to enter or leave the shaft () and a tension adjustor () capable of adjusting the tension of the connector ().

Surgical tool

A trocar including a distal-end tube portion that is disposed inside the body and has a first inner hole through which a medical device can be inserted; a proximal-end tube portion that is disposed outside the body and is connected to the distal-end tube portion, the proximal-end tube portion having a second inner hole that communicates with the first inner hole and has an axis which can be disposed in a direction not parallel to an axis of the first inner hole; and a movement facilitating portion that is disposed on at least one of the inner surface of the first inner hole and the inner surface of the second inner hole to facilitate the movement of the medical device inside the inner hole.

Trocar

Provided is a medical instrument which has improved operability of an insertion portion and can guide a distal end of the insertion portion to an intended position. The medical instrument includes: an insertion portion () which is inserted into a body cavity; a rotor () which is provided in an outer circumferential surface of the insertion portion () and has its rotational axis arranged in a direction along an axis of the insertion portion (); and a rotary drive unit which rotates the rotor () around the rotational axis.

Medical instrument

An appropriate stereoscopic image of a subject is readily acquired. Provided is a stereoscopic endoscope device including two image capture elements spaced apart from each other and disposed at a distal end of an insertion section to be inserted into a subject; an angle changing mechanism that changes a relative angle between optical axes of the image capture elements; a distance sensor that detects the distance from the image capture elements to the subject; and a controller that controls the angle changing mechanism on the basis of the distance detected by the distance sensor.

Provided is a guide sheath that is prevented from coming out of a body cavity so as to allow for stable operation. A tubular guide sheath that guides an insertion section of a medical device to be inserted into a body cavity includes a base-end opening that is provided at a base end of the guide sheath and into which the insertion section is inserted; a distal-end opening that is provided at a distal end of the guide sheath; a flexible bent section that is provided at the distal end of the guide sheath and is elastically bent; and an exit opening that is provided in an outer side surface of the bent section and from which the insertion section extends out.

Guide sheath and guide sheath system

An endoscope and a surgical instrument are easily manipulated to desired positions and orientations independently while the state of treatment with the surgical instrument can be easily observed using an endoscopic image. Provided is a medical-device guiding method comprising a U-shape forming step of placing both ends of a guide wire outside the pericardium and placing the guide wire, with an intermediate portion curved in a substantially U-shape in the pericardial cavity; an endoscope inserting step of inserting an endoscope into the pericardial cavity along the guide wire from one end of the ends placed outside the pericardium in the U-shape forming step; a guide-unit inserting step of inserting the guide unit into the pericardial cavity along the guide wire from the other of the ends placed outside the pericardium in the U-shape forming step; and an opposing step of opposing the distal end portions of the endoscope and the guide unit, which are inserted into the pericardial cavity in the endoscope inserting step and the guide-unit inserting step, respectively, at intermediate positions of the guide wire.

In an optical switch, fibers in a fiber array are arranged in a row. When a region where lights input into or output from the fibers in the fiber array intersect is taken as an intersecting position C, and an axis parallel to the fibers in the fiber array and passing through the intersecting position C is taken as a Z axis, then a distance &#x3b4; between a core of a desired fiber among the fibers and an optical axis of a corresponding one of the lenses varies depending on a distance S of the desired fiber from the Z axis.

Optical switch
