In the device disclosed in the above publication, a brush portion is provided at the tip of the insertion portion. Such an insertion portion is configured such that a wire is inserted through the inside of the close contact spring, and the wire is used to strengthen the insertion portion, and both ends of the wire are fixed to the close contact spring to prevent the close contact spring from excessively extending. ing.

いう欠点があった。However, in the conventional cleaning brush for an endoscope, since both ends of the wire constituting the insertion portion are fixed to the close contact spring, when the insertion portion is wound in a loop shape, Due to the difference in the radius of curvature between the wire and the contact spring, a phenomenon occurs in which the wire is pulled by the contact spring. Due to this phenomenon, the conventional cleaning brush has a drawback that the insertion portion becomes hard and the operability of the insertion portion and the conduit insertion performance deteriorate.

特徴とする。In order to achieve the above object, the present invention provides a brush part for brushing a pipe provided in an endoscope, and an insertion part having the brush part connected to the tip. In the cleaning brush for an endoscope, the insertion portion is configured by inserting a wire through a close contact spring, and the length difference between the close contact spring and the wire when the insert portion is wound in a loop. And a damper portion for absorbing the pressure is provided.

性が向上する。According to the first aspect of the present invention, since the insertion portion including the close contact spring and the wire is provided with the damper portion for absorbing a difference in length between the close contact spring and the wire, the insert portion has a loop shape. The difference in length between the close contact spring and the wire, which occurs when the wire is wound around, is absorbed by the damper portion. Accordingly, even when the insertion portion is formed in a loop shape, the phenomenon that the wire is pulled by the close contact spring does not occur, and the operability of the insertion portion and the conduit insertion property are improved.

に引っ張られるという現象は生じない。According to the second aspect of the present invention, the damper portion is formed by fixing one end of the close contact spring to one end of the wire and setting the other end of the close contact spring to a free end with respect to the wire. Thus, when the insertion portion is wound in a loop, the other end of the close contact spring escapes from the wire, so that the phenomenon that the wire is pulled by the close contact spring does not occur.

る。The insertion shaft portion 54 includes a contact spring 64 and a wire 6.
And 6. Also, the tip portion 6 of the contact spring 64
4A has no wire 66 inserted therein and is formed in a coarse winding. Thereby, the bending property of the brush part 52 is improved. Most of the close contact springs 64 except for the distal end portion 64A are wound tightly to provide rigidity.
A wire 66 is inserted into the inside and reinforced, and the hardness of the insertion shaft portion 54 is adjusted. A distal end 66A of the wire 66 is fixed to the distal end side wire fixing member 64B provided at the distal end of the densely wound portion of the contact spring 64 by solder or the like. On the other hand, the rear end portion 64C of the contact spring 64
Are free ends that are not fixed to the wire 66, and are shorter than the wire 66. The rear end (free end) 64C of the close contact spring 64 constitutes a damper portion 56. The damper section 56 is covered with a rubber tube 57 so as not to be soiled during use.

A hole 69 is opened in the connecting plate 68, and a wire 72 is passed through the hole 69 and is connected in a ring shape. The annular wire 72 is formed in such a size that a finger of an operator of the cleaning brush 50 can be inserted. The wire 72
Instead, a ring-shaped body such as a rubber band may be applied.

Next, the brush part 52 is moved from the treatment tool insertion port 26 to the treatment tool insertion channel 3.
Insert at 0. At this time, the insertion shaft portion 54 is gradually released from the loop and is inserted into the treatment tool insertion channel 30. When the brush portion 52 reaches the treatment instrument insertion channel outlet 28, the grip portion 58 pushes and pulls the insertion shaft portion 54 so that the brush portion 52 is inserted into and removed from the treatment instrument insertion channel 30, and the treatment instrument is inserted. The inner surface of the insertion channel 30 is cleaned.

Since C is not fixed to the wire 66 but is a free end, when the insertion shaft portion 54 is wound in a loop, the free end moves in a direction approaching the connecting member 68 as shown in FIG. I do. Therefore, the phenomenon that the wire 66 is pulled by the close contact spring 64 does not occur.

End 68A
By contacting with, its elongation is regulated. Therefore, the cleaning brush 50 for the endoscope is moved to the treatment instrument insertion channel 3.
It can be withdrawn from 0 without any problem.

挿入性が向上する。The damper portion 82 of the endoscope cleaning brush 80 shown in FIG. 5 is configured by forming a predetermined length at the rear of the close contact spring 64 into a coarse winding 64D. Thereby, when the insertion shaft portion 54 is wound in a loop shape, the coarse winding 64D of the close contact spring 64 is formed.
Since the portion contracts and absorbs the difference in length between the contact spring 64 and the wire 66, the phenomenon that the wire 66 is pulled by the contact spring 64 does not occur. Therefore, also in this endoscope cleaning brush 80, the operability of the insertion shaft portion 54 and the conduit insertion performance are improved.

4, the wire 65B extends from the casing 96 as shown by the arrow B against the urging force of the spring 98. As a result, the difference between the lengths of the wires 65A and 65B and the contact spring 64 is absorbed, and in this case also, the operability of the insertion portion and the conduit insertion performance are improved.

ないので、挿入部の操作性及び管路挿入性が向上する。As described above, according to the cleaning brush for an endoscope according to the present invention, the insertion portion consisting of the close contact spring and the wire has the damper portion for absorbing the difference in length between the close contact spring and the wire. Is provided, the difference in length between the close contact spring and the wire generated when the insertion portion is wound in a loop shape can be absorbed by the damper portion. Thus, according to the present invention, even when the insertion portion is wound in a loop shape, the phenomenon that the wire is pulled by the close contact spring does not occur, so that the operability of the insertion portion and the conduit insertion property are improved.
