本考案は体腔内に挿入される内視鏡の挿入部を
案内する内視鏡用ガイドチユーブに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope guide tube that guides the insertion portion of an endoscope inserted into a body cavity.
たとえば胃の噴門部や食道などにおいてその体
内の狭腔に続く閉塞部（病変部）を内視鏡によつ
て観察や処置を行なう際、内視鏡の挿入路を確保
するため、上記狭腔を拡張するガイドチユーブを
用いるのが普通である。第１図は体内の狭腔１内
に従来のガイドチユーブ２を通じて内視鏡の挿入
部３を挿入した状態を示すが、その閉塞部（病変

胃液などの分泌液や出血液が涌溜し、閉塞部（病
変部）４を覆つてしまうことによつて内視鏡によ
る観察や処置を妨げることがあつた。 For example, when using an endoscope to observe or treat a blockage (lesion) that follows a narrow cavity in the body, such as the cardia of the stomach or the esophagus, the narrow cavity is It is common to use a guide tube to extend the FIG. 1 shows a state in which the insertion section 3 of the endoscope is inserted through a conventional guide tube 2 into a narrow cavity 1 in the body. Secretions such as gastric juice and bleeding blood accumulate and cover the obstructed area (lesioned area) 4, thereby interfering with observation and treatment using an endoscope.
本考案は上記事情に着目してなされたもので、
その目的とするところは狭腔内の閉塞部（病変
部）に当接する先端部内に涌溜する胃液などの分
泌液や出血液を排除する手段を設けてそれが溜ら

障を来たさないようにした内視鏡用ガイドチユー
ブを提供することにある。 This invention was made with attention to the above circumstances,
The purpose of this is to provide a means to remove secretions such as gastric juice and blood that accumulate in the distal end that comes into contact with the obstructed part (lesioned part) in the narrow cavity, and to prevent this from accumulating. An object of the present invention is to provide a guide tube for an endoscope that does not interfere with observation or treatment.
以下、本考案の一実施例を第２図ないし第５図
にもとづいて説明する。 An embodiment of the present invention will be described below with reference to FIGS. 2 to 5.
第２図中１１はその内視鏡用ガイドチユーブ１

（図示しない。）に連通する吸引チユーブ（図示し
ない。）を接続するようになつている。 11 in Fig. 2 is the guide tube 1 for the endoscope.
This guide tube body 11 is formed by attaching and fixing a cylindrical mouthpiece 14 to the proximal end of a flexible insertion tube 13. Each inner diameter is larger than the outer diameter of an insertion section 16 of an endoscope, which will be described later. Further, inside the distal end portion 13a of the insertion tube 13 in the guide tube body 11, the inner lumen 1 is provided.
A suction port 17 facing 5 is formed. and,
This suction port 17 extends within each wall of the insertion tube 13 and the mouthpiece 14 and is connected to a suction conduit 18 formed along the longitudinal axis of the guide tube body 11 . Note that the suction line 18 is connected to the insertion tube 1.
3, and a small hole 20 formed in the wall of the cap 14 so as to communicate with the side hole 19. It is blocked. The base 14 also has a connection port 22 that communicates with the small hole 20.
A suction tube (not shown) that communicates with a vacuum source (not shown) is connected to this connection port 22 .
次に、上記内視鏡用ガイドチユーブ１２の使用
方法とその作用を説明する。 Next, a method of using the guide tube 12 for an endoscope and its function will be explained.
たとえば第５図で示すように食道などの狭腔Ａ
の途中にある閉塞性の病変部Ｂを内視鏡によつて
観察あるいは処置する場合、その狭腔Ａに内視鏡
の挿入部１６を直接に挿入すると、その狭腔Ａの
粘膜や病変部Ｂが挿入部１６の先端面に密着して
しまい、観察できなくなる。そこで、この内視鏡
用ガイドチユーブ１２を使用するのである。 For example, as shown in Figure 5, narrow spaces such as the esophagus A
When observing or treating an obstructive lesion B in the middle of the narrow cavity A with an endoscope, inserting the insertion section 16 of the endoscope directly into the narrow cavity A will cause damage to the mucous membrane and the lesion in the narrow cavity A. B comes into close contact with the distal end surface of the insertion section 16, making it impossible to observe it. Therefore, this guide tube 12 for an endoscope is used.
まず、ガイドチユーブ本体１１の挿入管１３を
狭腔Ａの病変部Ｂまで挿入し、その先端部１３ａ
の先端を病変部Ｂ当てることによりその先端部１
３ａの内部に病変部Ｂを出つ張らせる。そして、
内視鏡の挿入部１６を病変部Ｂとの間に一定の間
隔をあけた状態でその内視鏡により観察あるいは
処置を行なう。 First, insert the insertion tube 13 of the guide tube body 11 to the lesion B of the narrow cavity A, and
By applying the tip of the lesion B to the lesion B, the tip 1
The lesion B is made to protrude inside 3a. and,
Observation or treatment is performed using the endoscope with a fixed distance between the insertion section 16 of the endoscope and the lesion B.
この際、病変部Ｂからの出血液や胃のほうから
涌き出てくる胃液などの分泌液はその先端部１３
ａ内に溜ろうとするが、これを吸引口１７および
吸引管路１８を通じて真空吸引することにより外
部に排出し、その先端部１３ａ内に溜らないよう
にするのである。したがつて、出血液や分泌液な
どで病変部Ｂが覆われることを防止でき、内視鏡
による観察や処置に支障を来たさない。 At this time, the blood bleeding from the lesion B and secretions such as gastric juice flowing out from the stomach are removed from the tip 13.
However, by vacuum suctioning through the suction port 17 and the suction conduit 18, it is discharged to the outside to prevent it from accumulating in the distal end portion 13a. Therefore, the lesion B can be prevented from being covered with bleeding blood, secreted fluid, etc., and observation and treatment using an endoscope will not be hindered.
特に、上記吸引口１７はガイドチユーブ本体１
１の内腔１５に臨んで形成されているので、この
ガイドチユーブ１２を食道などの狭腔Ａに挿入さ
せてもその狭腔内壁面によつて閉塞されることが
ない。つまり、出血液や分泌液などを確実かつす
みやかに排出できる。 In particular, the suction port 17 is connected to the guide tube body 1.
Since the guide tube 12 is formed facing the inner lumen 15 of the guide tube 12, even if the guide tube 12 is inserted into a narrow cavity A such as the esophagus, it will not be blocked by the inner wall surface of the narrow cavity. In other words, bleeding blood, secretions, etc. can be discharged reliably and quickly.
