20110032350 | ILLUMINATION DEVICE AND IMAGE ACQUISITION APPARATUS - An illumination device includes a first illumination section having a first light source which emits white light and a first optical system for applying, with a first directional characteristic, the white light emitted from the first light source, and a second illumination section having a second light source which emits light of a color different from the color of the light from the first light source, and a second optical system for applying the light emitted from the second light source with a second directional characteristic such that the light is applied to a second application area contained in and smaller than a first application area based on the first directional characteristic. | 02-10-2011 |
20120200687 | LIGHT SOURCE APPARATUS, ELECTRONIC IMAGE ACQUIRING APPARATUS, ELECTRONIC IMAGE OBSERVATION APPARATUS, ENDOSCOPE APPARATUS, CAPSULE ENDOSCOPE APPARATUS - A light source apparatus is designed in accordance with an object, and following elements and phosphors are disposed in a casing, a first light emitting element that emits a light in a first irradiation mode, which is selected so that a light emission band has a portion that overlaps a first-specific-band, a first phosphor selected so as to include the first-specific-band in an excitation band and include a second-specific-band in a fluorescence-emission-band, a second phosphor selected so that an excitation intensity compared with the first phosphor is low in the first-specific-band, and high in a second-fluorescence-excitation-band at a short wavelength side in a second-irradiation-band and a fluorescence-emission-band includes the second-irradiation-band other than the second-fluorescence-excitation-band, and a second light emitting element that emits a light in a second irradiation mode, which is selected so that a light emission band is included in the second-fluorescence-excitation-band. | 08-09-2012 |
20140046134 | GUIDE SHEATH - 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. | 02-13-2014 |
20140221748 | STEREOSCOPIC ENDOSCOPE DEVICE - 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. | 08-07-2014 |
20140303437 | STEREO-ENDOSCOPE DEVICE, STEREO-ENDOSCOPE SYSTEM, AND STEREO-ENDOSCOPE ROBOT - 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. | 10-09-2014 |
20140323801 | IMAGE SYSTEM FOR SURGERY AND METHOD FOR IMAGE DISPLAY - 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. | 10-30-2014 |
20140357948 | ILLUMINATION OPTICAL SYSTEM FOR ENDSCOPE AND ENDOSCOPE - 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. | 12-04-2014 |
20150250498 | TROCAR - 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. | 09-10-2015 |
