Abstract:
Provided is an endoscope apparatus provided with: an elongated insertion portion 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 and that acquires two images having parallax for the same imaging subject; an identifying portion 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 that processes the image so that the image of the object identified by the identifying portion is removed from the image.
Abstract:
Provided is an endoscope system provided with an endoscope main unit including a shaft, an operating portion, and an image-acquisition unit; an arm that supports the main unit and that can change the attitude and the position of the main unit by using a plurality of joint portions; a memory that records angle information of the respective joint portions; a CPU; and a mode-switching switch that switches between a recording operating mode and an automatic operating mode, wherein, in the case in which operating mode is switched to the automatic operating mode from the recording operating mode, the CPU reproduces changes in the rotating angles of the respective joint portions in time-series in reverse order based on the angle information recorded in the memory in the recording operating mode, thus returning the attitude and the position of the main unit to the initial state of the recording operating mode.
Abstract:
Provided is a guide sheath that is maintained in a desired shape and at a desired position even after a dilator has been pulled out therefrom so that the guide sheath can guide an insertion section to an appropriate position. A cylindrical 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 a guide sheath body and into which the insertion section is inserted; a distal-end opening that is provided at a distal end of the guide sheath body and from which the insertion section extends out; and a shape maintainer that extends in an axial direction at an inner surface of the guide sheath body and has photo-curable resin that is cured by light.
Abstract:
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.
Abstract:
A method of controlling an endoscope includes, inserting an insert part having an imaging unit at a distal end through the body; making an imaging direction of the imaging unit variable by bending of a bending part, wherein the bending part is included in the insert part; detecting an amount of insertion of the insert part through the body; and determining whether the bending part is to be bent or not on the basis of operation of a direction input part depending on the amount of insertion.
Abstract:
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 including an optical fiber for guiding excitation light emitted from a light source; a first mirror and a second mirror disposed facing a light emission end at a distal end of the optical fiber and diffusing the excitation light emitted from the light emission end; and a phosphor on which the excitation light diffused by the first mirror and the second mirror is incident and which emits fluorescence.
Abstract:
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.
Abstract:
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.
Abstract:
Appropriate stereoscopic images of an affected site are easily acquired. Provided is a stereo-endoscope device that includes an inserted portion that can be inserted into a subject's body; two imaging devices that are disposed on the inserted portion with a space therebetween; driving units that change the relative angle of the optical axes of the imaging devices; a distance sensor for detecting the distance to the imaging devices from a treatment part of a treatment instrument that is inserted into the subject's body and is used to treat the affected site; and a swivel control section that controls the driving units based on insertion information of the treatment instrument, the insertion information including the distance detected by the distance sensor.
Abstract:
A surgical system includes: a medical device; a measuring portion that measures a three-dimensional position of an organ in the interior of a body cavity; a setting portion that sets, on the basis of the three-dimensional position of the organ, a non-interference region, which is a space in the interior of the body cavity excluding the organ; a detecting portion that detects a three-dimensional position of the medical device in the interior of the body cavity; a calculating portion that calculates, on the basis of the three-dimensional position of the medical device, a medical-device occupying region of the medical device in the interior of the body cavity; a predicting portion that predicts interference between the medical device and the organ on the basis of the positional relationship between the non-interference region and the medical-device occupying region; and an alerting portion that alerts an operator when interference is predicted.
