    Abstract: Eine medizinische Vorrichtung gemäß der vorliegenden Erfindung umfasst: einen Einführabschnitt (1), der mit einem flexiblen Abschnitt (1a) versehen ist, der so flexibel ist, dass er zwischen einer ersten Form, die sich entlang der Längsachse erstreckt, und einer zweiten Form, die in eine Richtung gebogen ist, die sich mit der Längsachse schneidet, verformt zu werden; ein Verformungsunterstützungselement (2), das am Einführabschnitt (1) angebracht ist, um entlang einer Oberfläche des Einführabschnitts (1) beweglich zu sein; einen Positionseinstellungsteil, der mit einem proximalen Endabschnitt des Einführabschnitts (1) verbunden ist und der die relative Position des Verformungsunterstützungselements (2) in Bezug auf den Einführabschnitt (1) einstellt; und einen Biegeabschnitt (2b), der am flexiblen Abschnitt (1a) oder einem Längsabschnitt des Verformungsunterstützungselements (2) bereitgestellt ist und der eine gebogene Form aufweist. Das Verformungsunterstützungselement (2), das im flexiblen Abschnitt (1a) angeordnet ist, übt eine Antriebskraft auf den flexiblen Abschnitt (1a) aus, um eine Verformung zwischen der ersten Form und der zweiten Form zu bewirken.

    Abstract: Provided is a fluorescence observation apparatus (100) including a light source (3) that radiates illumination light and excitation light onto a subject; a return-light-image generating portion (61) and a fluorescence-image generating portion (62) that generate a return-light image (G1) and a fluorescence image (G2) of the subject, respectively; a fluorescence detecting portion (63) that detects a fluorescence region in the fluorescence image (G2); a return-light-image adjusting portion (65) that adjusts gradation values of the return-light image (G1); a superimposed-image generating portion (66) that generates a superimposed image (G3) by using the return-light image (G1'), in which the gradation values have been adjusted, and the fluorescence image (G2); and a coefficient setting portion (64) that sets, in the case in which the fluorescence region is detected by the fluorescence detecting portion (63), a degree-of-adjustment, by which the gradation values of the return-light image (G1) are adjusted by the return-light-image adjusting portion (65), so that the gradation values of the return-light image (G1) are decreased as compared with the case in which the fluorescence region is not detected by the fluorescence detecting portion (63).

    Abstract: The diagnosability of diseased parts is improved by precisely correcting fluorescence images without being affected by specular reflection and without being affected by thick blood vessels. Provided is a fluorescence observation apparatus (1) that includes a light source unit (2) that radiates, onto an observation target site (S), illumination light that is in the wavelength band absorbed by a blood vessel, first excitation light that includes the wavelength band of the illumination light and generates autofluorescence by exciting an autofluorescent substance in the blood vessel, and second excitation light that is in a different wavelength band from the first excitation light and generates agent fluorescence by exciting fluorescent dye that selectively stains normal tissue and abnormal tissue; an image-acquisition unit (15, 16) that obtains respective images by capturing reflected light, autofluorescence, and agent-fluorescence, obtained by radiating the illumination light, and the first and the second excitation light onto the same observation target site (S); and an image processing unit (4) that extracts a blood-vessel image from the obtained reflected-light image, obtains a reference image by applying interpolation to an area in the autofluorescence image corresponding to the extracted blood-vessel image, and corrects the agent-fluorescence image, obtained by the image-acquisition unit, based on the obtained reference image.

    Abstract: Provided is an observation apparatus (100) comprising a light source (3) that irradiates a subject (X) with illumination light and special light that acts on a specific region of the subject (X); a return-light-image generating portion (61) that generates a return-light image (G1) by capturing return light coming from the subject (X) due to irradiation with the illumination light; a special-light-image generating portion (62) that generates a special-light image (G2) by capturing signal light coming from the subject (X) due to irradiation with the special light; an extraction portion (63) that extracts the specific region from the special-light image (G2); and an enhancement processing portion (64) that performs enhancement processing, which is based on return-light image information, on the return-light image (G1), in a region corresponding to the extracted specific region.
