Abstract:
1. An endoscope apparatus comprising: an insertion part which has an imaging mechanism at a distal end portion and which is bendable and elongated; a display part which displays an image acquired by the imaging mechanism; a manipulating part which performs curving manipulation of the insertion part; and a housing provided with the display part and the manipulating part at a front face thereof, and connected to the insertion part at a back face opposite to the front face, wherein the manipulating part comprises: wherein the housing has an upper portion where the display part is provided, and a lower portion where the manipulating part is provided and to which the insertion part is connected, wherein a proximal end of the insertion part connected to the lower portion, and the manipulating rod are coaxially arranged in a neutral state of the manipulating rod, wherein the back face of the lower portion includes a first finger grip portion having a first slope and a second finger grip portion having a second slope, wherein the insertion part is connected to the lower portion between the first finger grip portion and the second finger grip portion, wherein the first finger grip portion, which is provided above the proximal end of the insertion part, includes a first finger grip and a second finger grip, wherein the second finger grip is provided between the first finger grip and the proximal end of the insertion part, such that the second finger grip is provided below the first finger grip in a vertical direction, and the proximal end of the insertion part is provided below the second finger grip in the vertical direction, wherein the housing is configured to be held by a single hand of a user, such that (i) a thumb of the single hand of the user is located at a distal end of the manipulating rod, (ii) first and second other fingers in the single hand of the user are located respectively on the first finger grip and the second finger grip of the first finger grip portion, (iii) third and fourth other fingers in the single hand of the user are located on the second finger grip portion, and (iv) the thumb and the other fingers face each other, and wherein a swinging center of the manipulating rod is located inside a region specified by the first slope of the first finger grip portion and the second slope of the second finger grip portion, and by the distal end of the manipulating rod protruding from the front face in a side view of the housing.
