【従来の技術及び発明が解決しようとする課題】内視鏡
は高価な医療機器であるために再使用するが、再使用す

た、内視鏡に汚れがあると確実な消毒ができないので、
消毒前に洗浄を行なうことは重要である。そこで、内視
鏡の消毒を確実に実施するため、内視鏡の汚れを予め落
としてから消毒を行なうようにしている。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.
【０００３】ところで、内視鏡の外表面部位の汚れはガ
ーゼやスポンジなどを使って拭き取ったり、内視鏡洗浄
装置で洗浄する場合は洗浄槽内に内視鏡を収容して超音
波洗浄したりしていた。このように内視鏡の外表面部位
の汚れについては比較的容易に落とすことができる。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.
【０００４】しかし、内視鏡には汚物を吸引したり処置
具類を通すための管路、対物レンズ表面の曇り対策等の
為に水と空気を供給する送気送水管路、及び他の用途に
合わせた各種の管路を有しており、これら管路はいずれ
も細く長いものであるため、これまでのブラッシングに
よる洗浄や流液による洗浄では能率的に洗浄できなかっ
た。ましてや内視鏡の管路の中をブラッシングにより洗
浄する作業は非常に面倒であり、多くの手間がかかって
いた。また、流液により管路の中を洗浄する方法は比較
的長時間を要するという問題があった。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.
【０００５】一般に内視鏡の管路用チューブは軟性であ
ることが必要なことから、そのほとんどがテフロンチュ
ーブなど、撥水性のある柔軟なチューブで構成されてい
る。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.
【０００６】しかし、鉗子を挿入する鉗子口、吸引ボタ

なっているなど、構造がチューブ部分に比べて複雑にな
っている。つまり、洗浄という観点から見ると、柔軟な
チューブ部分よりも金属製部材で形成された部分の洗浄
の方が難しい。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.

このため、超音波洗浄中に開口部の内部には超音波洗浄
が作用し難かった。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.

を効率的に行うようにしたものである。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.

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.

る。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.

とが好ましい。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.

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.

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.
