Problems solved by technology

[0005] However, in the structure of the endoscope disclosed in JP 2011-120863 A, since a stepped portion is formed by forming a vertical surface on the annular convex portion, it is difficult to be applied, especially, to be introduced into a living body. Problems with Medical Endoscopes
Furthermore, due to the stepped portion, there is also a problem that it is difficult to perform brushing before and after use.
[0006] In addition, in the structure of the endoscope disclosed in JP 2011-255088, by providing a land portion for the observation window, fluid remains on the land portion for the observation window, and the remaining water tends to return to the observation window to obstruct the field of view. question

Embodiment Construction

[0024] Next, the endoscope of the present invention will be described. In addition, in the following description, the drawings based on each embodiment are schematic, and it should be noted that the relationship between the thickness and the width of each part, the ratio of the thickness of each part, etc. are different from the actual ones. Between the drawings, Parts with different dimensional relationships and ratios may also be included.

[0025] Next, an embodiment of the present invention will be described with reference to the drawings.

[0026] figure 1 It is an overall configuration diagram of an endoscope apparatus having the endoscope of the present invention. Such as figure 1 As shown, an endoscope device 1 receives the video signal and displays an endoscope image through an endoscope 2, a light source device 3 that supplies illumination light, and a video processor 4 that generates an electrical signal for driving an imaging device into a video signal. A monit...

Abstract

An endoscope (2) comprises: a window part (15) which protrudes at a prescribed height from a flat part (22); an air supply / water supply nozzle (19) which is disposed from the flat part (22) in opposition to the window part (15) and discharges a fluid toward the surface of the window part (15); and an oblique part (23) which is formed in a peripheral edge part of the window part (15). In an oblique angle of the oblique part (23) to the flat part (22), a second angle of elevation (theta2) is made greater than a first angle of elevation (theta1), said first angle of elevation (theta1) of a direction along a first axis which passes through the center of the window part (15) of the discharge direction of the fluid which is discharged from the air supply / water supply nozzle (19) and said second angle of elevation (theta2) of a direction along a second axis which is orthogonal to the first axis at the center of the window part.

Description

technical field [0001] The present invention relates to the structure of the front end surface of an insertion portion in an endoscope. Background technique [0002] Conventionally, with regard to endoscopes, various techniques have been proposed in order to realize the cleanability and water repellency of the surface of an objective lens serving as an observation window provided at a distal end portion. [0003] For example, JP-A-2011-120863 discloses an endoscope technique in which an annular convex portion is provided around the observation window, and an inclination inclined toward the outer diameter direction is formed on the annular convex portion. Surface and vertical surface, use the vertical surface to catch the water droplets formed due to the water supply from the air supply and water supply nozzles, and prevent them from flowing into the observation window. [0004] And, for example, JP-A-2011-255088 discloses an endoscope technique in which an observation windo...
