Problems solved by technology

[0009] In the attachment and detachment mechanism of Patent Document 2, when attaching and detaching the motor unit and the insertion part, it is necessary to operate the engaging / disengaging button to move the driving side coupling and the driven side coupling in the axial direction. , It is necessary to adjust the rotational position of the driven side coupling so that the pin of the driven side coupling can pass through the pin guide, and the attachment and detachment of the motor unit and the insertion part become troublesome

Embodiment Construction

[0065] Hereinafter, various embodiments of the present invention will be described with reference to the drawings.

[0066] Figure 1 to Figure 5 The first embodiment of the present invention is shown.

[0067] A schematic configuration of an endoscope system will be described with reference to FIG. 1 .

[0068] The endoscope 30 of the endoscope system has an elongated insertion portion 32 for insertion into a body cavity. A bending portion 34 that bends in four directions up, down, left, and right is arranged at a front end portion of the insertion portion 32 , and an insertion / extraction portion 36 is arranged at a base end portion of the insertion portion 32 . Here, an angle mechanism is built into the insertion part 36 , and an angle operation wire extending from the angle mechanism passes through the insertion part 32 and is connected to the front end of the bending part 34 . The angle operation wire is operated forward and backward by the angle mechanism, whereby the ...

Abstract

An attachment and detachment mechanism includes convex and concave engaging portions provided in first and second couplings respectively and extending in a radial direction of first and second shaft portions, the convex engaging portion is to be slidably inserted into and removed from the concave engaging portion along a longitudinal direction of the concave engaging portion, the convex and concave engaging portions includes basic positions where the longitudinal directions of the convex and concave engaging portions correspond to the attachment and detachment direction of the first and second main body portions and the convex and concave engaging portions are insertable into and removable from each other, and the attachment and detachment mechanism further includes a guide mechanism to guide one engaging portion such that the one engaging portion is disposed at the basic position in conjunction with the attachment or detachment of the first and second main body portions.

Description

technical field [0001] The present invention relates to a detachable mechanism having a driving side coupling and a driven side coupling that are connected to and separated from each other as the driving side body and the driven side body are attached and detached, and an endoscope equipped with the same. Background technique [0002] Conventionally, an attaching / detaching mechanism having a driving side coupling and a driven side coupling that are connected to and separated from each other along with attachment and detachment of the driving side body and the driven side body has been used. [0003] For example, Patent Documents 1 and 2 disclose endoscopes having such an attachment and detachment mechanism. These endoscopes have a motor unit and an insertion unit which are detachable from each other. In the motor unit, a disk-shaped driving side coupling is coaxially connected to a front end portion of the driving side shaft portion. On the other hand, in the elongated ins...
