Abstract: To provide a sensor-equipped hood capable of detecting force applied to the hood without narrowing an operating field viewed through the hood. A sensor-equipped hood protrudes from a tip end portion of an endoscope main body, and is attached to the tip end portion. The sensor-equipped hood includes a transparent tubular hood main body and a fiber Bragg grating (FBG) sensor fixed to a first fixing point of the hood main body and having a Bragg grating. In the FBG sensor, the wavelength of reflected light at the Bragg grating changes based on fluctuation of the first fixing point in the hood main body.

Abstract: An endoscopic hood and an endoscope to which the endoscopic hood is attached improve visibility for the user. The endoscopic hood includes a body formed of a transparent cylinder having two open ends and a conductive film embedded integrally in the body. The conductive film includes a transparent film and a transparent electrode pattern on the transparent film. The transparent electrode pattern includes a transparent electrode, a transparent wire portion extending from the transparent electrode, and a transparent terminal at an end of the transparent wire portion. The transparent terminal is exposed from the body. The endoscope includes an insertion portion insertable into a body of a subject, the endoscopic hood attached to a distal end of the insertion portion, and at least one wire having one end electrically connected to the transparent terminal and another end electrically connected to an external device.
