Description

  The present invention relates to an endoscope pipe cleaning device and a pipe cleaning method using a flexible brush filament.

In the endoscope, a treatment instrument insertion channel, a suction line, and the like are provided. Since various pipelines are contaminated by body fluids or chemicals of the subject, it is necessary to perform brushing washing after using the endoscope to keep them clean. In conventional brushing cleaning, after the cleaning brush is inserted from one end of the conduit to the other end, it is repeatedly pulled out by hand in the direction opposite to the insertion direction many times, so that the inner wall of the conduit is repeated several times. Also rub with a cleaning brush to remove dirt. Recently, in order to reduce the number of times the cleaning brush is inserted, it has been proposed to use a flexible brush linear body 200 as shown in FIG. 13 instead of the conventional cleaning brush. The flexible brush linear body 200 includes a flexible shaft 210 and a plurality of brush portions 220 provided at one end side of the flexible shaft 210 with a space (see Patent Document 1).

The suction line 45 includes a first suction line 45a that opens to the insertion end 41a, a second suction line 45b that opens to the suction base 46, and the first and second suction lines 45a and 45b. It consists of a suction cylinder 45c that relays. The suction cylinder 45c is normally closed by a suction button (not shown). Although not shown, examples of the endoscope conduit provided in the endoscope 40 include an auxiliary water supply conduit and a treatment instrument insertion channel.

Next, a method for cleaning the suction pipe 45 will be described.
First, the flexible brush linear body 20 is attached to the electric hoist 30. Specifically, the open / close case 312 of the electric hoist 30 is opened to expose the brush insertion path 314, and the second roller 350 is held at the free position (the position of FIG. 4A) by the roller turning knob 353. In this state, the flexible brush linear body 20 is inserted into the brush insertion passage 314 from the base end side (the side opposite to the brush portion 22), and the flexible brush linear strip is inserted from the inlet opening 314a of the brush insertion passage 314 as shown in FIG. Pull out the body 20 by a sufficient length. Then, the second roller 350 is moved to the locked position by the roller turning knob 353, and the proximal end portion of the flexible brush linear body 20 (flexible shaft 21L) is sandwiched between the pair of rollers 340 and 350 so as to be able to advance and retract. (See FIG. 4B).

  Next, the suction button is removed from the opening of the suction cylinder 45 c of the endoscope 40, and the opening serving as the insertion opening for the flexible brush linear body 20 is exposed. Subsequently, the distal end side (brush 22 side) of the flexible brush linear body 20 is inserted into the first suction conduit 45a from the suction port of the insertion portion distal end 41a, and the entire brush portion 22 is opened to the suction cylinder 45c. It protrudes outward from (FIG. 6 state). Alternatively, the flexible brush linear body 20 is inserted into the first suction conduit 45a from the opening of the suction cylinder 45c, and the entire brush part 22 is projected outward from the suction port of the insertion portion tip 41a (not shown). ).

  Then, the hoisting switch 320 of the electric hoist 30 is turned on. Then, the electric motor 331 is driven by the motor driver 332, and the pair of rollers 340 and 350 starts to rotate forward. When the pair of rollers 340 and 350 rotate in the forward direction, the flexible brush linear body 20 is pulled from the base end side by the rotational force and is pulled out from the first suction conduit 45a (the arrow direction in FIG. This is the drawing direction of the flexible brush filament 20). The drawn flexible brush linear body 20 is drawn into the inlet opening 314 a of the brush insertion passage 314, passes through the brush insertion passage 314, is discharged from the outlet opening 314 b, and travels toward the storage device 360.

Since the amount of discharge from the outlet opening 314b of the flexible brush linear body 20 and the amount of protrusion of the vinyl tubular body 365 from the case 364 are substantially proportional, the flexible brush linear body 20 is shown in FIG. When the amount of discharge increases, the protruding amount of the vinyl tubular body 365 from the case 364 also increases.

  When the flexible brush linear body 20 is pulled out from the first suction conduit 45a in this way, the plurality of brush portions 22 sequentially pass through the first suction conduit 45a, and the inner wall of the first suction conduit 45a. Is cleaned by brushing, and the dirt attached to the inner wall of the first suction pipe 45a is removed. Since the flexible brush linear body 20 is provided with three brush portions 22, when the flexible brush linear body 20 is inserted once, the same cleaning effect as that obtained when brushing cleaning is performed three times is obtained. It is done. When all the flexible brush filaments 20 are discharged from the electric hoist 30, the hoisting switch 320 of the electric hoist 30 is turned off. In this discharge completion state, the entire flexible brush linear body 20 is accommodated in the vinyl cylindrical body 365, and the flexible brush linear body 20 and the electric hoist 30 are separated.

Subsequently, the second suction pipe 45b is cleaned by brushing.
First, the screwing of the female screw 363 and the male screw 316 of the case 364 is released, the case 364 and the vinyl cylindrical body 365 are removed from the electric hoist 30, and the flexible brush linear body is removed from the vinyl cylindrical body 365. 20 is taken out and the flexible brush filament 20 is washed. When the cleaning of the flexible brush linear body 20 is completed, the accommodating device 30 and the flexible brush linear body 20 are attached to the electric hoist 30 again. Then, the flexible brush linear body 20 is inserted into the second suction pipe 45b from the opening of the suction cylinder 45c, and the entire brush part 22 is projected outward from the suction base 46 of the connector part 44 (FIG. 6 state). Alternatively, the flexible brush linear body 20 is inserted into the second suction conduit 45b from the suction cap 46 of the connector portion 44, and the entire brush portion 22 is protruded outward from the opening portion of the suction cylinder 45c (not shown). ). Then, the hoisting switch 320 of the electric hoist 30 is turned on. Then, the flexible brush linear body 20 is discharged to the outside of the electric hoist 30 while being pulled out, and is accommodated in the vinyl tubular body 365. Then, during the drawing operation, the plurality of brush portions 22 that pass through the second suction conduit 45b remove the dirt attached to the inner wall of the second suction conduit 45b.
The cleaning order of the second suction pipe 45b and the first suction pipe 45a may be reversed.

As described above, in this embodiment, since the flexible brush linear body 20 is wound up by the electric hoist 30, the user simply turns on the hoisting switch 320 of the electric hoist 30 and the flexible brush linear body 20 is turned on. The body 20 can be easily pulled out from the endoscope line (in this embodiment, the suction line 45), and the labor and time required for pulling out the flexible brush filament 20 can be greatly reduced.
In addition, since the flexible brush linear body 20 pulled out from the endoscope duct by the electric hoist 30 passes through the electric hoist 30 and is wrapped in the vinyl cylindrical body 365, the flexible brush wire It is hygienic because filth and the like adhering to the strip 20 are not scattered around.

  Further, in the present embodiment, the electric hoist 30 is pulled out from the endoscope duct and the flexible brush linear body 20 is wound around the inside of the main body case 310 and is not stored. The main body case 310 (electric hoist 30) is made smaller than the storage type in which the extracted flexible brush linear body 20 is stored in the main body case (housing) 310. be able to. Furthermore, in this embodiment, since the flexible brush linear body 20 provided with the some brush part 22 is used, it is the same as the case where the brushing washing | cleaning of the number of times equal to the number of the brush parts 22 is performed by one brush insertion / removal operation | work. A cleaning effect is obtained.

In the present embodiment, a brush insertion path 314 is provided in the main body case 310 of the electric hoist 30, and the pair of rollers 340 and 350 are arranged in a state of protruding partly in the brush insertion path 314. The entire rollers 340 and 350 may be provided in the brush insertion path 314.
A cylindrical body formed of a flexible material other than vinyl may be used instead of the vinyl cylindrical body 365.

  In the above embodiment, the first suction conduit 45a and the second suction conduit 45b are each washed once by brushing. However, even if the first suction conduit 45a and the second suction conduit 45b are brushed several times, Well, in this way, the dirt attached to the inner walls of both suction pipes 45a and 45b can be more reliably removed. In this way, when cleaning multiple times, each time the drawing operation is completed once, the accommodation device 360 is removed from the electric hoist 30 and the flexible brush linear body 20 is taken out from the vinyl tubular body 365, The flexible brush filament 20 is washed. Then, the accommodation device 360 and the flexible brush linear body 20 are attached to the electric hoist 30 again, and the flexible brush linear body 20 is inserted into the first suction conduit 45a or the second suction conduit 45b, The flexible brush filament 20 is pulled out from the first suction line 45a or the second suction line 45b by the hoist 30.
