Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0032] Such as figure 2 As shown, the endoscope 1 is mainly composed of an insertion unit 2 , an operation unit 3 , and a universal cord 4 .

[0033] The insertion part 2 is inserted into body ducts such as the stomach and the large intestine. The insertion portion 2 is configured such that a rigid distal end portion 2a, a curved portion 2b, and a flexible flexible tube portion 2c are continuously provided in this order from the distal end side. The bending portion 2b is configured to be able to bend freely in the vertical direction, for example.

[0034]An imaging element (not shown) as an observation unit (not shown) is provided at the distal end portion 2 a of the insertion portion 2 . In addition, a nozzle (not shown), a treatment instrument channel opening (not shown) through which the treatment instrument is drawn out, and the like are provided on the distal en...

Abstract

The endoscope (1) has: an operation part (3) having a grip part (3A) and a grip auxiliary surface (35a) on which fingers are arranged when the surgeon grips the grip part (3A); an insertion part (2) having A bending part (2b) is provided on the front end side; at least one knob (5) is arranged on one side of the operation part (3), and the bending part (2b) is turned by rotating the rotating shaft (5a) as the center. Bending; and at least two air and water supply buttons (6a), suction buttons (6b), which protrude from the fluid control button configuration part (32) on the upper side of the operating part (3), and are arranged in the operating part (3) In the direction of the longitudinal axis of each button (6a, 6b), the switch roots (6ar, 6br) of each button (6a, 6b) are arranged so that they are located on the outermost diameter locus of the up and down knob (5) projected onto a plane whose normal line is the rotation center axis. (5S) and the two intersection points (P1, P2) where the fluid control button arrangement part (32) intersects.

Description

technical field [0001] The present invention relates to an endoscope including a bending operation knob for bending a bending portion provided in an insertion portion and a plurality of function switches for operating endoscope functions in an operating portion. Background technique [0002] In recent years, endoscopes have been widely used in the medical and industrial fields. Endoscopes include an optical fiber endoscope using an image fiber as an image transmission unit, and an electronic endoscope having an imaging element built in a distal end portion of an insertion portion. [0003] In an electronic endoscope, an endoscopic observation image of a site to be observed captured by an imaging element is displayed on an observation screen for observation or the like. On the other hand, in optical fiber endoscopes, observation is performed directly with the naked eye through the eyepiece unit, or observation is performed by attaching a camera to the eyepiece unit and displ...
