Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an endoscope cleaning tool for brushing and cleaning the inside of an endoscope after using the endoscope.

[0002]

2. Description of the Related Art In general, brushes for cleaning the inside of a pipe of an endoscope are provided as follows.
Brush bristles are radially implanted at the distal end of a flexible elongate shaft, and a handle is provided at the proximal end. Is to be inserted and removed.

[0003]

However, since the shaft is formed longer than the length of the conduit of the endoscope, it is very long. For this reason, when inserting the distal end into the conduit of the endoscope, it is not easy to make the distal end straight along the axis of the conduit, and it is difficult to perform the insertion operation. Also, when inserting and removing the tube from the endoscope, the handle on the hand side was swung and hit the surroundings, which was bothersome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cleaning tool for an endoscope in which the endoscope can be easily inserted into and removed from the duct.

[0005]

In order to achieve the above object, the present invention provides an endoscope conduit cleaning tool in which brush bristles are radially implanted on a flexible and elongated shaft. The brush body is wound around a rotatable drum, and an operation handle is provided for manually rotating the drum so that the brush body is fed out from the drum toward the end of the endoscope or wound around the drum. It is characterized by having.

The brush bristles may be implanted only near the tip of the shaft. In addition, the brush bristles may be intermittently planted at a plurality of locations on the shaft, or the brush bristles may be continuously planted on the shaft in a wide area from the front side. Further, a brush cleaning means for applying a cleaning liquid to the brush main body at a position extended from the drum may be provided.

[0007]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, which is used when brushing and cleaning the inside of a pipe of an endoscope (such as an air supply / water supply pipe or a suction pipe) after using the endoscope. The state is shown.

The endoscope 10 has an operation section 11 connected to a base end of an insertion section 12 mounted on the mounting table 1. The endoscope 10 is provided with an air supply / removal operation valve after removing an air supply / water supply operation valve and a suction operation valve. The inlet opening 13 to the water supply pipe and the inlet opening 14 to the suction pipe are in a state of opening upwards side by side.

The in-pipe cleaning tool 20 is configured to be surrounded by a housing 21, and two rotatable drums 22 are housed in the housing 21. Each drum 22 has
A brush 232 is attached to a flexible elongated shaft 231.
Is wound around a brush body 23 which is formed by radially implanting the brush body. In this embodiment, the brush bristles 232
Is implanted only at the tip of the shaft 231.

A portion of the brush body 23 extended from the drum 22 includes a slit 24 formed in the housing 21.
And can be inserted almost straight into the air supply / water supply channel entrance opening 13 or the suction conduit entrance opening 14 of the endoscope 10 (in such a position, the in-pipe cleaning tool 20 is located). Are located).

The two drums 22 are rotatable independently of each other, and each drum 22 is provided with an operation handle 25 for manually rotating the drum 22 from outside. Therefore, the operation handle 25 is pinched with a fingertip and the drum 22 is
By rotating the brush body 2 from the drum 22.
3 or the brush body 23 can be wound around the drum 22.

FIG. 2 is a side sectional view of the cleaning tool 20 in a pipe.
As clearly shown in FIG.
And a cleaning liquid discharge pipe 28 for spraying a cleaning liquid onto the brush body 23 passing therethrough.
And a cleaning liquid discharge pipe 29 for discharging the cleaning liquid injected into the cleaning chamber 27.

According to the endoscope pipe cleaning tool 20 of the embodiment configured as described above, the brush body 23 is inserted into the pipe of the endoscope 10 after the endoscope 10 is used. At this time, the brush 22 is rotated downward by gripping the operation handle 25 with a fingertip, and the brush body 23 is extended downward from the drum 22, so that the brush body 23 is straightened.
3, 14 can be inserted.

If the drum 22 is rotated in the reverse direction, the brush body 23 that has been fed can be wound around the drum 22. In addition, you may provide the urging | biasing means for giving the power for winding.

During such an operation, an extra portion of the shaft 231 is wound around the drum 22 so that it does not hinder the operation, and the brush body 23 is connected to the conduit openings 13 and 14.
Can be easily inserted and removed.

FIGS. 3 and 4 show a second embodiment of the present invention, in which the shaft 231 of the brush body 23 has a length several times (for example, 3 to 10 times) the length of the conduit of the endoscope 10. In addition, the brush bristles 232 are intermittently planted at a plurality of locations (for example, several tens to one hundred and several tens) of the shaft 231. The illustration of the housing 21, the operation handle 25, and the like are omitted.

In this manner, as shown in FIG. 3, after inserting the brush body 23 into the conduit of the endoscope, the scissors 100
For example, the shaft 231 is cut into a suitable length, the brush body 23 used for cleaning is discarded, and a new brush body 23 can be used sequentially.

FIG. 5 shows a third embodiment of the present invention. Only the point that the brush bristles 232 are continuously implanted from the distal end side to the shaft 231 over substantially the entire length with respect to the shaft 231 is the above-described second embodiment. This is different from the embodiment.

In this way, not only is the cleaning property during brushing improved, but also it is not necessary to select the location where the shaft 231 is cut, which is convenient.

[0020]

According to the present invention, an extra portion of the shaft of the brush body is wound around the drum when the endoscope is inserted into and removed from the conduit, so that the drum does not hinder the insertion and removal operation, and the drum can be removed. By rotating the brush body, the brush body can be straightly opposed to the conduit opening of the endoscope and can be easily inserted and removed.
