Problems solved by technology

On the other hand, the cleaning brush spreads randomly in the storage part due to the restoring force, and the winding diameter of the cleaning brush and the distance from the winding position to the conveying part become inconstant.
Therefore, the extension force applied to the conveying part is unstable, and there is a possibility that the penetrating object conveying device for an endoscope cannot stably send out or pull in the cleaning brush from the opening at the distal end.

example 2

[0084] In the embodiment, the side wall 42b of the restricting portion 42e is formed to be tapered in diameter from the side of the first chamber 42d toward the side of the second chamber 42f, but an annular reduced diameter portion may be attached and formed.

[0085] Figure 12 It is an explanatory drawing explaining the state which accommodated the cleaning brush B of the linear member conveyance apparatus 1 in the linear member storage part 242 in the modification 2 of embodiment of this invention. In the description of Modification 2 of the embodiment, the same reference numerals are assigned to the same configurations as those in the embodiment, and description thereof will be omitted.

[0086] The linear member storage portion 242 has a chamfer at the shoulder portion 141a, and is formed in a bottomed cylindrical shape having a narrowed portion from the shoulder portion 141a toward the opening 42a.

[0087] The restriction part 242e is a diameter-reduced part formed in...

Abstract

The linear member delivery device (1) comprises a linear member storage part (42), a delivery part (43b) and a guide (43a). The linear member storage part (42) is cylindrical with a bottom and includes: a bottom (42c ); an opening (42a); a side portion (42b); a restricting portion (42e), which is a reduced-diameter portion disposed at a position separated from the bottom (42c) by a predetermined distance (P), and the restricting portion (42e) has a ratio The inner diameter (We) of the inner diameter (Wc) of the bottom (42c) is small; the first chamber (42d) accommodates the wire-like member in a state where the wire-like member is wound; and the second chamber (42f) makes the wire-like member The linear member is accommodated in a stretched state, and the conveying unit (43b) is used to convey the linear member.

Description

technical field [0001] The invention relates to a wire-shaped member conveying device. Background technique [0002] In the past, in order to be able to clean the endoscope pipeline contaminated by use, there is an endoscope that can insert or pull out a cleaning brush as a linear member into the endoscope pipeline. Use penetrating material delivery device. For example, Japanese Patent Application Laid-Open No. 2015-181801 discloses a cleaning brush that can be stored in the storage part to the endoscope pipeline, and can pull the cleaning brush sent out into the storage part and wind it up for storage. Penetration delivery device for speculum. [0003] However, in the conventional penetrating object conveying device for endoscope, if the cleaning brush is drawn into the storage portion and wound up for storage, the restoring force of the cleaning brush generates a protruding force from the opening of the storage portion. And a protruding force is applied to the conveying...
