摘要:
The invention provides a method of controlling an endoscope in which an insert part having an imaging unit at a distal end is inserted through the body. The insert part includes a bending part capable of bending movement to make an imaging direction of the imaging unit variable. The method implements amount-of-insertion detection processing to detect an amount of insertion of the insert part through the body, and implements bending part control processing on the basis of an amount of insertion detected by the amount-of-insertion detection processing to determine whether the bending part is to be bent or not on the basis of operation of a direction input part.

Even in the case in which peripheral tissue or the like in close proximity is captured only in one image, the efficiency at which an observer performs procedures is prevented from being deteriorated. Provided is an endoscope apparatus (1) provided with: an elongated insertion portion (3) that is inserted into a body; an image-acquisition portion that has an imaging optical system disposed at a distal end of the insertion portion (3) and that acquires two images having parallax for the same imaging subject; an identifying portion (6) that identifies an image of an object, which is in close proximity to the imaging optical system, that is captured only in one of the two images acquired by the image-acquisition portion; and a close-proximity-image-removal processing portion (7) that processes the image so that the image of the object (S) identified by the identifying portion (6) is removed from the image.

An image system for surgery includes: a three-dimensional imaging unit acquiring two images having parallax by capturing an image of a portion; a display unit displaying two images acquired by the three-dimensional imaging unit individually for both left and right eyes, or displaying a same image for both left and right eyes; a detection unit detecting that a treatment device that performs treatment on the portion or the three-dimensional imaging unit is in an operating state in which to initiate treatment on the portion; and a display control unit switching from displaying one of images on the display unit to displaying two images on the display unit when the detection unit detects the three-dimensional imaging unit or the treatment device is in the operating state in which to initiate treatment on the portion.

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.

A surgical system (100) includes: a medical device (1); an organ measuring means (7) for measuring a three-dimensional position of an organ (D) in the interior of a body cavity; a non-interference-region setting portion (10) that sets, on the basis of the three-dimensional position of the organ (D), a non-interference region, which is a space in the interior of the body cavity excluding the organ (D); a medical-device detecting means (8) for detecting a three-dimensional position of the medical device (1) in the interior of the body cavity; a medical-device-occupying-region calculating portion (11) that calculates, on the basis of the three-dimensional position of the medical device (1), a medical-device occupying region of the medical device (1) in the interior of the body cavity; an interference predicting portion (12) that predicts interference between the medical device (1) and the organ (D) on the basis of the positional relationship between the non-interference region and the medical-device occupying region; and an alerting portion (13) that alerts an operator when interference is predicted by the interference predicting portion (12).

摘要:
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.

A wide range is illuminated with a sufficient light amount while a diameter of an insertion portion is reduced. Provided is an illumination optical system for endoscope (1) including an optical fiber (6) for guiding excitation light emitted from a light source; a first mirror (9) and a second mirror (10) disposed facing a light emission end (6a) at a distal end of the optical fiber (6) and diffusing the excitation light emitted from the light emission end (6a); and a phosphor (11) on which the excitation light diffused by the first mirror (9) and the second mirror (10) is incident and which emits fluorescence.
