Problems solved by technology

[0005] However, in the case where the operating portion is formed in an L-shape like the technology disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2009-189684, due to the hard grip portion and the anti-folding portion, the extension direction of the operating portion body is different. Since the endoscope is extended at a predetermined angle, it may be difficult to store the endoscope compactly in the storage case or the cleaning tank of the sterilizer, etc.
[0006] In addition, when the operating part is bent into an L-shape, the center of gravity of the operating part tends to be separated from the grasping part. burden on the wrist, etc., making it difficult to ensure good grip and operability

Abstract

The endoscope (2) has a rear grip portion (22) extending along a second length axis (O2) which is a first length axis ( O1) The direction of bending, wherein the anti-folding part (40) covering the universal cable (12) extending from the base end side of the rear grip part (22) is connected to the rear grip part ( 22) are connected at the base end side, and the direction of the anti-folding part (40) can be changed to point to the inner side of the bending direction of the rear gripping part (22) relative to the operating part main body (20) through the movable connecting part (41) The first direction and the second direction point to the outside of the rear grip part (22) relative to the bending direction of the operation part main body (20).

Description

technical field [0001] The present invention relates to an endoscope having an operation unit capable of adopting various gripping forms. Background technique [0002] Conventionally, an endoscope is used to observe a target site in a subject by inserting an elongated insertion portion into a body cavity or the like, or to perform various treatments using a treatment instrument inserted into a treatment instrument channel as necessary. [0003] As such an endoscope, a flexible endoscope in which a distal end portion, a bending portion, and a flexible tube portion are sequentially arranged from the distal end side is widely used. When inserting the insertion portion of such a flexible scope into the subject, the operator or the like grasps the operation portion with one hand while holding the flexible tube portion with the other hand, and presses the insertion portion into the subject. . At this time, the operator or the like can bend the bending part in a desired direction...
