Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an endoscope cleaning apparatus for cleaning an endoscope.

[0002]

2. Description of the Related Art An endoscope is reused because it is an expensive medical device, but cleaning and disinfection of the endoscope is essential for reuse. Also, if the endoscope is dirty, it cannot be disinfected reliably, so
It is important to perform cleaning before disinfection. Therefore, in order to ensure the disinfection of the endoscope, the dirt of the endoscope is removed in advance before the disinfection.

By the way, dirt on the outer surface of the endoscope is wiped off with a gauze or sponge, or when the endoscope is cleaned by an endoscope cleaning device, the endoscope is housed in a cleaning tank and ultrasonically cleaned. It was. In this way, dirt on the outer surface of the endoscope can be removed relatively easily.

However, the endoscope has a conduit for sucking dirt and passing treatment tools, an air / water supply conduit for supplying water and air to prevent fogging of the surface of the objective lens, and other conduits. Since it has various pipe lines according to the application, and all of these pipe lines are thin and long, it has not been possible to efficiently wash them by the conventional washing by brushing or washing with a flowing liquid. Furthermore, the work of cleaning the inside of the duct of the endoscope by brushing is very troublesome and takes a lot of time and effort. Further, the method of cleaning the inside of the pipe with the flowing liquid has a problem that it takes a relatively long time.

Generally, the tube for the duct of the endoscope is required to be flexible, so that most of the tube is made of a water-repellent flexible tube such as a Teflon tube.

However, a part of the conduit, such as a forceps port for inserting forceps and a cylinder for inserting a suction button / air supply / water supply button, is made of a metal member such as SUS having low water repellency. Furthermore, the structure is more complicated than that of the tube portion because the metal member has a branched structure. That is, from the viewpoint of cleaning, it is more difficult to clean the portion formed of the metal member than the flexible tube portion.

It should be noted that since the site of the conduit made of these metals is normally open to the outside, it seems that ultrasonic waves for cleaning the outer surface work sufficiently. In order to wash the inside of the pipe line with flowing liquid, a connector for connecting a tube connected to a liquid feed pump is attached to the opening, or a lid for closing the opening is attached.
Therefore, it was difficult for the ultrasonic cleaning to act inside the opening during the ultrasonic cleaning.

The present invention has been made in view of the above problems, and ultrasonic vibration is applied from the opening of the endoscope to the inside of the internal conduit to clean the inside of the internal conduit of the endoscope. It is intended to efficiently clean the metal part in the opening of the internal conduit where it is difficult to clean dirt.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION (First Embodiment) A cleaning apparatus according to a first embodiment of the present invention will be described with reference to FIGS. The cleaning apparatus of this embodiment is a system in which an ultrasonic transducer is applied to a connecting tool connected to an endoscope.

An endoscope 1 to which the cleaning apparatus of this embodiment is connected.
An outline of the basic pipeline structure of No. 0 is shown in FIG. This Figure 1
As can be seen from the above, the endoscope 10 is provided with an air supply pipe line 11, a water supply pipe line 12, and a suction pipe line 13 for suctioning filth or the like and passing treatment tools as internal pipe lines.

The air supply line 11 and the water supply line 12 are the endoscope 10.
Are joined together in the vicinity of the tip of the insertion portion into the human body to form one air / water feeding conduit 14, and this air / water feeding conduit 14 is connected to a nozzle 15 provided at the tip of the endoscope 10. An air / water feeding cylinder 16 is provided as an opening in the inner water passage between the air feeding / feeding conduit 11 and the water feeding / feeding conduit 12, and the air / water feeding cylinder 16 is fitted with a button (not shown) to feed / feed An air / water supply operation valve for controlling the operation of water supply is configured.

A suction cylinder 17 is provided in the middle of the suction pipe line 13 as an opening of the internal pipe line, and a button (not shown) is fitted into the suction cylinder 17 to form a suction operation valve for controlling the suction operation. It is like this. Further, a forceps port 18 for guiding the treatment instrument into the duct 13 is provided in the middle of the suction duct 13 on the human body insertion side. The forceps port 18 also constitutes the opening of the internal conduit of the endoscope 10.

Further, the insertion portion 19 of the endoscope 10 and the like are flexible. Therefore, each of the above-mentioned pipelines 11, 12, 1
Most of 3, 14 are made of a flexible tube such as Teflon (registered trademark), but the cylinders 16 and 17 and the forceps port 18 require functional strength, so SU
It is made of metal such as S.

By the way, such pipelines 11, 12, 1
When washing the inside of the liquids 3 and 14 with a flowing liquid, various patterns can be considered for the flow of the cleaning liquid.
The cylinders 16 and 17 and the forceps ports 18 which are the openings of the pipes 3 and 14 are covered, or the conduits 11 and 1 are inserted from there.
The solution should be sent into the inside of 2, 13, and 14.

As a general method, as shown in FIG. 4, the suction cylinder 17 is covered with a lid, and the air / water supply cylinder 1
The connection tools 1 and 2 are attached to 6 and the forceps opening 18, and the liquid is fed into the ducts 11, 12, 13, and 14 from here. Therefore, the connecting tool 1 as shown in FIG. 2 is mounted on the cylinder 16 and the forceps port 18, and the connecting tool 2 having no liquid feeding function as shown in FIG. 3 is mounted on the suction cylinder 17. To

The connecting tool 1 shown in FIG. 2 is in the form of a connecting means having a liquid feeding function, and the connecting tool 1 is a connecting portion (connecting means) formed of an elastic body such as rubber into a thick ring shape. 21
And a pipe-shaped main body 22 made of a material that easily reflects ultrasonic waves, for example, a metal member, and an ultrasonic transducer (ultrasonic wave generation means) 23 connected to the side wall surface of the main body 22. . The connecting portion 21 is fitted and attached to a collar portion 22a formed at the tip of the main body 22. To the other end of the main body 22, a liquid sending means for supplying a liquid to the internal conduit of the endoscope 10 is connected. Here, the tube 24 from a liquid feed pump (not shown) is connected. As described above, the main body 22 has a liquid supply pipe line formed therein by a pipe-shaped member that easily reflects ultrasonic waves. That is, at least the ultrasonic transducer 23 to the connecting portion 21 are made of a member that easily reflects ultrasonic waves. For this reason, in this portion, the ultrasonic wave is transmitted by reflection, so that the ultrasonic wave is less attenuated.

The ultrasonic vibrator 23 is driven by connecting it to a driving means (not shown). This ultrasonic transducer 23
Is a waterproof structure because it is installed in a liquid when the endoscope 10 is washed.

As shown in FIG. 2, a part of each of the cylinders 16 and 17 and the forceps port 18 projects from the exterior member of the endoscope 10, and a brim-shaped projection 26 is provided at or near the tip of the projection. Has been. Then, the connecting portion 21 of the connecting tool 1 is fitted into the end portion having the projection 26, and is connected to the endoscope 10 while forming a supply conduit 27 for feeding the liquid into the internal conduit of the endoscope 10.

In this connected state, the main body 22 of the connecting device 1 is
And the member on the side of the endoscope 10 are not in direct contact with each other. That is, the distance between the main body 22 of the connector 1 and the endoscope main body 25 is longer than the length of the protruding portions of the cylinders 16 and 17 and the forceps port 18 protruding from the outer surface of the endoscope main body 25. Is configured. The connecting portion 21 is located between the main body 22 of the connecting tool 1 and the endoscope main body 25. That is, it is provided between the liquid supply conduit, the connecting means, or the connecting means and a member on the internal conduit side of the endoscope to which the connecting means is connected.

Here, the connecting portion 21 of the connecting tool 1 and the endoscope 10, that is, the member of the connecting portion 21 and each cylinder 16,
17 and the forceps port 18 are not completely brought into close contact with each other, but a slight gap is provided between them. For this reason, when the connector 1 is connected to the endoscope 10 to deliver the liquid, the endoscope 10
A small amount of liquid leaks from the gap between the member on the side and the connecting portion 21, and the air remaining in the connecting tool 1 is also discharged to the outside of the pipeline, so that all the connecting surfaces including both of them are discharged. The site can be filled with liquid.

Such an action is not limited to the case where the size of the connecting portion 21 of the connecting tool 1 is taken into consideration. Connection part 21 during liquid transfer
Since it is only necessary to cause a slight liquid leakage between the endoscope body 25 and the endoscope body 25, the two are usually kept in close contact with each other, and the elastic body of the connecting portion 21 is deformed by the pressure during liquid feeding. A gap may be generated.

On the other hand, the connector 2 having no liquid feeding function shown in FIG. 3 is a connecting means having a form excluding the constituent parts of the connector 1 having the liquid feeding function. Therefore, in the connector 2, the metal main body 31 has a lid shape instead of a conduit shape, and the ultrasonic transducer 23 is attached to the outer surface of the main body 31 as the lid portion. Of course, in the case of this connecting tool 2, the tube 24 is unnecessary. Further, in the state of being connected to the endoscope 10, the connecting tool 1 described above is used.
The main body 31 is configured so as not to come into direct contact with the member on the endoscope 10 side. Further, when liquid is fed to the internal duct of the endoscope 10, a slight liquid leak occurs between the connecting portion 21 and the endoscope body 25, as in the case described above. Since liquid leakage occurs at the connecting portion 21 in this manner, air is excluded, and the space 32 surrounded by the cylinders 16 and 17, the forceps port 18, the main body 31, and the connecting portion 21 is removed.
Becomes filled with liquid.

Next, an example of use of the cleaning apparatus of this embodiment will be described. First, install the endoscope 10 in the cleaning tank,
Further, as shown in FIG. 4, the air / water feeding cylinder 16 and the forceps port 18 of the endoscope 10 are equipped with the connector 1 having the liquid feeding function as shown in FIG. 17
Then, the connector 2 having no liquid feeding function as shown in FIG. 3 is attached. The tubes 24 from the liquid feed pump (not shown) are connected to the middle portions of the internal conduits 11, 12, and 13 of the endoscope 10, respectively. At this time, both ends of the internal conduits 11, 12, 13 are open to the outside of the endoscope 10. This endoscope 10 is installed in the cleaning tank.

After the above-mentioned preparations are completed, the cleaning operation of the cleaning device is started, and in accordance with this, the internal conduit 11 of the endoscope 10 is passed through the tube 24 from the liquid feed pump (not shown).
The cleaning liquid is sent to 12 and 13, respectively.

When the ultrasonic transducer 23 is driven in this state, the supply conduit 2 is passed through the main bodies 22 and 31 of the connectors 1 and 2.
Ultrasonic waves are applied to the liquid filled in 7 or the space 32 to ultrasonically clean the inner walls of the air / water feeding cylinder 16 and the forceps port 18. Further, the inner wall of the internal conduits 11, 12, 13 of the endoscope 10 can be cleaned. As a result, in addition to the flushing of the internal conduit of the endoscope 10, the insides of the air / water feeding cylinder 16, the suction cylinder 17, and the forceps port 18 that are difficult to clean can be cleaned by ultrasonic waves.

Since the members forming the cylinders 16 and 17 and the forceps port 18 are made of metal, not resin or the like, ultrasonic waves are easily reflected on the surface of the metal member. Therefore, the ultrasonic waves reach not only the inner walls of the cylinders 16 and 17 and the forceps port 18 but also deep parts thereof. Specifically, ultrasonic vibrations are transmitted to a connection portion with a flexible tube extending inward. Furthermore, each cylinder 1
Since the inner surfaces of 6, 7 and the forceps port 18 are generally complicated and relatively rough, ultrasonic vibrations are transmitted to a deep portion, specifically, a connection portion with a flexible tube. As a result, the inner wall of the metal tube of each of the cylinders 16 and 17 and the forceps port 18, which are difficult to clean due to dirt, is reliably cleaned with ultrasonic waves.

Here, the frequency of the ultrasonic vibration generated by the ultrasonic vibrator 23 is not particularly limited, but each cylinder 1
The inner diameter (diameter) of 6, 17 and the forceps opening 18 is almost 1
Since it is 0 mm or less, a frequency of about 1 MHz is preferable. If the frequency is lower than this, the wavelength becomes large, so that cleaning unevenness is likely to occur. In this case, however, it is possible to prevent the occurrence of cleaning unevenness by changing the position of the abdomen by simultaneously performing the liquid feeding. The reason for this is as follows. Since no apparent vibration occurs in the ultrasonic node, the cleaning effect is not obtained at this portion, and conversely, the cleaning effect is most obtained at the belly portion of the ultrasonic wave. Particularly at low frequencies, the wavelength is long, so that the washable part and the non-washable part become noticeable. As a countermeasure against this, ultrasonic vibration is applied to the cleaning liquid being fed, and the ultrasonic vibration is transmitted by the cleaning liquid. At this time, if the ultrasonic transmission medium is moving, the positions of the abdomen and the node of the ultrasonic wave are moved, and the insides of the cylinders 16 and 17 and the forceps port 18 can be cleaned evenly.

In the case of the above method, ultrasonic vibrations are transmitted to the flexible tube portion of the internal duct, although it is being attenuated. Thereby, a cleaning effect on the tube portion can be expected. The thicknesses of the main bodies 22 and 31 of the connectors 1 and 2 are at least an integral multiple of λ / 2 with respect to the wavelength (λ) of the ultrasonic wave on at least the surface to be joined to the vibration surface of the ultrasonic transducer 23. Is preferred.

By the way, when the ultrasonic transducer 23 is driven, the main bodies 22 and 31 of the connectors 1 and 2 also slightly vibrate ultrasonically, but the connecting portion 21 makes this ultrasonic vibration.
It also has a role as a suppressing means for suppressing the transmission of ultrasonic vibrations that is not transmitted to the.

(Second Embodiment) In the first embodiment, the connecting tools 1 are attached to the cylinders 16 and 17 and the forceps opening 18 of the endoscope 10.
It was a method of connecting 2 by a fitting type. Therefore, the connecting portion 21 interposed between the bodies 22 and 31 of the connecting tools 1 and 2 and the member of the endoscope 10 is made of an elastic body. In some cases, a connection method different from this connection method may be adopted. In this case, for example, as shown in FIG. 5, an elastic body 35 may be provided on a part of the main body 22 of the connector 1 in an intervening manner. Further, also in the case of the connector 2, it is preferable to provide an elastic body on a part of the main body 31 of the connector 2.

The point is that it is sufficient to buffer ultrasonic vibrations.
A system as shown in FIG. 6 may be used. This is because the endoscope main body 25 and the main body 22 of the connection tool 1 are utilized by utilizing the pressure at the time of liquid feeding.
A gap 37 is provided between the and. That is, the main body 22 of the connector 1 is the fixture 4 connected to the endoscope body 25.
3 is supported by a support plate 41 and a spring 42. The main body 22, the support plate 41 and the spring 42 are the fixtures 4
3 is slidable in the axial direction, and the main body 22 is biased in the connecting direction.

When the connector 1 is connected to the endoscope 10, the cylinder 1 to be connected is the main body 22 of the connector 1.
6 or 17 or the opening of the forceps mouth 18 is faced. In this state, the fixing tool 43 is slid forward-backward in FIG. Then, as shown in FIG. 6, the brim-shaped projection 26 and the fixture 43 mesh with each other, and the entire connector 1 is fixed to the endoscope 10. At this time, the main body 22 of the connector 1 is urged by the spring 42 and hits the open end of the cylinders 16 and 17 of the endoscope 10 or the forceps port 18, and the main body 22 is in close contact with the open portion. At the time of liquid, the body 22 of the connector 1 retracts against the biasing force of the spring 42 due to the pressure of the liquid, and a gap (space) 37 is formed in the portion that has been in close contact until then. At this time, if the ultrasonic transducer 23 is driven, the ultrasonic waves are transmitted to the endoscope 10 without the main body 22 directly touching the members of the endoscope 10.
Can be transmitted into the internal conduit of.

Since ultrasonic vibrations are also transmitted through the fixing members 43, it is preferable that the fixing members 43 be made of resin capable of suppressing the transmission of ultrasonic vibrations. Of course, if the endoscope 10 can withstand this ultrasonic vibration, it is not necessary to provide the elastic body or space as described above.

(Third Embodiment) The third embodiment will be described with reference to FIGS. 7 and 8. In this embodiment, the ultrasonic transducer is not attached to the connector submerged in the cleaning tank, but the ultrasonic transducer is attached to the outer wall of the cleaning tank of the endoscope cleaning apparatus.

As shown in FIG. 7, a metal flexible pipe 52 is arranged in the tank 51 from an arbitrary position in the tank 51 for housing and cleaning and disinfecting the endoscope. At the tip of the metal flexible pipe 52, the connector 1 having the above-described structure is arranged. However, the connection tool 1 here
There is no ultrasonic transducer installed in.

The metal flexible pipe 52 includes a buffer portion 53 provided on the outer wall of the tank 51 and the buffer portion 5.
It is connected to a liquid feed pump 55 via a pipe 54 connected to 3. An ultrasonic transducer 56 is arranged on the outer surface of the buffer portion 53, and this is driven by a driving means (not shown) incorporated in the endoscope cleaning apparatus.

The metal flexible pipe 52 is welded to the outer wall surface of the tank 51, as shown in FIG. A buffer portion 53 is arranged so as to cover the connection opening end of the metal flexible pipe 52. Tank 51 and buffer section 53
A sealing material 57 is disposed between the two for the purpose of sealing and vibration isolation, and is fixed by using a stud 61 and a nut 62 which are erected at a predetermined position in the tank 51. The pipe 54 is connected to the buffer portion 53 via a general pipe member. The ultrasonic transducer 56 is arranged on the outer surface of the buffer portion 73.

With this structure, the liquid is pumped by the operation of the liquid feed pump 55, inside the pipe 54 and the buffer portion 53,
Liquid is sent to the internal conduit of the endoscope by the conduit connected from the metal flexible pipe 52 to the connector 1.
At this time, when the ultrasonic transducer 56 is driven, ultrasonic waves are transmitted to the opening of the internal duct of the endoscope through the liquid filled in the above-mentioned path, and the same cleaning as in the first embodiment described above is performed. Expected to work.

The metal flexible pipe is required to be flexible because the position of the opening of the internal conduit differs depending on the type of endoscope, and it is made of metal that reflects ultrasonic waves. This is because

Further, in this embodiment, since the lid type connector 2 described in the first embodiment is eliminated, the liquid feeding type connector is also connected to the suction cylinder 17 of FIG. Therefore, the flow in the conduit is slightly different from that in the first embodiment, but there is no problem.

Now, as in the first embodiment, normally,
In the endoscope cleaning apparatus, as shown in FIG. 7, an ultrasonic transducer 58 for ultrasonically cleaning the outer surface of the endoscope has a cleaning tank 51.
It is provided in. Therefore, it is conceivable to utilize the ultrasonic oscillator 58 to vibrate the flexible pipe 52, transmit ultrasonic vibration to the liquid in the pipe, and ultrasonically clean each cylinder and forceps port. However, in such a method, there is a transmission loss due to the tank 51 and the flexible pipe 52, and as a result, the amplitude of the ultrasonic transducer 58 must be increased, which damages the outer surface of the endoscope, which is the original working site. It is not preferable because it may impose. Also, it is effective to cause cavitation with a relatively low frequency of the ultrasonic wave on the outer surface, but this causes a large wavelength, which is not suitable for each cylinder / forceps port having a small lumen. There are also problems. Therefore, the ultrasonic transducer 58 that processes the outer surface of the endoscope and the ultrasonic transducer 5 that performs ultrasonic cleaning of each cylinder / forceps port
It is actually suitable to consider 6 separately.

Further, various components not shown are connected to the tank 71. Therefore, it is preferable that the vibration is not transmitted as much as possible, and as a corresponding example, unnecessary vibration is buffered by the sealing material 57 as shown in FIG. Further, as shown in FIG. 7, the ultrasonic oscillator 58 is configured such that the plate 63 to which the ultrasonic oscillator 58 is applied and the wall of the tank 51 are separate bodies, and a member such as a sealing material (not shown) is sandwiched and fixed. preferable.

As described above, various levels of vibrations are transmitted to the metal flexible pipe 52 depending on the overall configuration. Since this is transmitted to the connection tool 1, whether or not the connection tool 1 has an elastic body may be determined with reference to this vibration level. In the case of the first embodiment, since the flexible tube is used, it is not necessary to consider this vibration level, and only the vibration due to the ultrasonic transducer applied to the connectors 1 and 2 may be the target.

As described above, unlike the first embodiment, it is not necessary to make the ultrasonic vibrator waterproof, and the number of ultrasonic vibrators can be reduced as a whole, so that the price is lower. However, it is possible to provide a system for effectively cleaning the endoscope without damaging it.

Since the drawing is a simplified one, it is not limited to this, and the number of the connectors 1 and the metal flexible pipes 52 is also the same. Further, although not shown, the metal flexible pipe 52 may be attached to and detached from the tank 51 using a connector.

The present invention is not limited to the above-mentioned embodiments, but can be applied to other forms.

[0050]

As described above, according to the present invention, by applying ultrasonic vibration into the conduit from the opening of the endoscope, it is difficult to clean the metal conduit in the conduit of the endoscope. The portion can be ultrasonically cleaned. As a result, it is possible to realize more reliable cleaning of the inside of the pipeline than the conventional flow cleaning or brushing cleaning, and as a result, it becomes easy to construct an effective cleaning system.
