【発明の詳細な説明】
この発明は口腔から体腔内に挿入して使用する
内視鏡に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope that is used by being inserted into a body cavity through the oral cavity.
一般に、この種の内視鏡が一旦患者の体腔内に
挿入されると、その診療が終了するまでは、それ
が引き抜かれることがなく長時間に亘つて挿入状
態が継続されることが多い。時間が経るに従つて
患者は咽頭部に唾液やその他の分泌物（以下、こ
れを単に唾液とよぶ。）をたまつてくるが、内視
鏡が挿入されているためにそれを飲み込むことも
できず、患者は苦痛や不快感を増大させてしま
う。 Generally, once this type of endoscope is inserted into a patient's body cavity, it is often not withdrawn and remains inserted for a long time until the medical treatment is completed. As time passes, the patient accumulates saliva and other secretions (hereinafter simply referred to as saliva) in the pharynx, which may be swallowed because the endoscope is inserted. This results in increased pain and discomfort for the patient.
この発明はこのような点に注目してなされたも

痛や不快感を軽減させることにある。 This invention was made with attention to these points, and its purpose is to form a suction port on the side surface of the flexible part of the endoscope, and to remove saliva accumulated in the pharynx through this suction port. The aim is to reduce the patient's pain and discomfort by inhaling it.

６が形成されている。 An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In Figure 1, 1
2 is the operating section of the endoscope, and 2 is the insertion section main body. The insertion section main body 2 has a flexible section 3 leading out from the operating section 1, and a distal end section 5 is provided at the distal end side of the flexible section 3 via a curved section 4, so that the insertion section main body 2 is configured in a series. A first suction port 6 is formed on the end surface of the tip portion 5 along with an observation window and an illumination window (both not shown).

A suction path 9 is provided. This suction path 9 is for sucking in foreign matter such as dirt and water droplets in the body cavity through the first suction port 6 of the distal end portion 5, and also serves as an insertion guide path for instruments such as forceps.

合致するように予め定められている。 A second suction port 10 having a relatively small diameter is formed on the side surface of the flexible portion 3, and a second suction path 11 is provided inside the flexible portion 3. The second suction port 10 is connected to the end of the second suction path 11 via a tube 12. The suction port 10 is predetermined so as to match the position corresponding to the patient's pharynx when the insertion portion main body 2 is inserted into the patient's body cavity.

療に耐え得るようになる。 Next, the effect will be explained. As shown in FIG. 3, when the insertion section main body 2 is inserted into a patient's body cavity through the mouthpiece a, the second suction port 10 formed on the side surface of the flexible section 3 faces the pharynx b of the patient. Then, by determining the time when saliva accumulates in the pharynx b, the switching operation valve 17 corresponding to the second suction path 11 is operated to apply suction force to the suction path 11, and the saliva is transferred to the suction port 10. Remove by inhalation. This significantly reduces the patient's pain and discomfort, and this reduction also allows the patient to endure longer treatment sessions.

する。 In the above embodiment, a second suction path is provided separately from the first suction path, and saliva is sucked and removed exclusively through this second suction path, but the present invention is not limited to this. Alternatively, the suction path may be used. That is, as shown in FIGS. 4 and 5,
A suction port 10a formed on the side surface of the flexible portion 3a is communicated with the first suction path 9a through a communication tube 21. Then, an on-off valve 23 is rotatably provided at the proximal opening of the communication tube 21 via a pin 22, and one end of the pin 22 is made to protrude outside the suction path 9a in an airtight manner. Install the pinion 24 and attach the rack 25 to this pinion 24.
The operating wire 26 is connected to the rack 25, and the operating wire 26 is guided to the operating section of the endoscope. Under normal conditions, the on-off valve 23 is closed to the proximal opening of the communication tube 21 as shown by the solid line in FIG. 4, and when saliva is inhaled, the on-off valve 23 is closed by the chain line in the figure As shown in , the suction port 10a is rotated so as to face the cross section of the suction path 9a, and in this state, saliva is sucked through the suction port 10a.
このような構成の場合には、挿入部本体内の吸
引路および操作部の切換え操作弁がそれぞれ単一
でよくなるから、構造が簡単でコスト的に有利と
なるとともに、小形化を図ることができる利点が
ある。 In the case of such a configuration, the suction passage in the insertion section main body and the switching operation valve of the operation section are each required to be single, so the structure is simple and cost-effective, and the device can be made smaller. There are advantages.

合致させるようにすればよい。 Note that depending on the type of endoscope, etc., the insertion depth of the insertion section is not constant, so it may be difficult to set the position of the suction port in the flexible part in advance at a position that corresponds to the pharynx. However, in such a case, a plurality of suction ports may be formed along the longitudinal direction of the flexible portion, and one of the suction ports may be made to correspond to the pharynx.

る。 As explained above, according to the present invention, a suction port is formed on the side surface of the soft part corresponding to the pharynx, and saliva in the pharynx is inhaled and removed through the suction port, thereby causing pain to the patient. It can reduce discomfort and discomfort, and is particularly effective during long medical treatment.
