動きが拘束されることにより、さらにその負担が
増加し、患者にとりきわめて苦しいものであつ
た。このため、この負担を少しでも軽減させるこ
とが強く望まれていた。 In general, when it is necessary to insert an endoscope deep into a body cavity from the oral cavity through the throat and esophagus, a tubular insertion aid is often used to guide the insertion portion of the endoscope through it. However, when using this insertion aid, the burden on the throat and esophagus in particular is significant. Furthermore, the burden on the patient increases as the movement of the head and neck is restricted, making it extremely painful for the patient. Therefore, it has been strongly desired to reduce this burden as much as possible.
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、使用時における患者の
負担を軽減できる内視鏡の挿入補助具を提供する
ことにある。 This invention was made with attention to the above circumstances,
The purpose is to provide an endoscope insertion aid that can reduce the burden on the patient during use.
以下、本考案の一実施例を第１図ないし第３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. 1 to 3.
第１図中１は挿入補助具を示し、この挿入補助

ある。 Reference numeral 1 in FIG. 1 indicates an insertion aid, and this insertion aid 1 is provided with an insertion port body 3 at the rear end of a flexible insertion tube 2, and further includes an insertion port 3 on the outer periphery of the rear end of the insertion tube 2. A mouthpiece 4 is fitted over the mouthpiece. The mouthpiece 4 is provided with a stopper screw 5,
By tightening the circumferential surface of the insertion tube 2, the position of the mouthpiece 4 is regulated. As shown in FIG. 3, the insertion tube body 2 has a distal end portion 6 and a rear end portion 7, each of which is composed of separate flexible members 8 and 9 of equal diameter, and is connected via a connecting tube 10. connected. That is, the ends of the flexible members 8 and 9 are respectively fitted into the coupling tube 10, and the thread 11 is wound around the outer side of the coupling tube 10 to connect and fix the flexible members 8 and 9. Furthermore, the flexible member 9 of the rear end portion 7 is made of a material having a lower hardness than the flexible member 8 of the front end portion 6, so that the rear end portion 7 is softer than the front end portion 6. be.
次に、上記挿入補助具１の使用方法を説明す
る。 Next, how to use the insertion aid 1 will be explained.
まず、内視鏡１２の可撓性挿入部１３を挿入口
体３からその挿入補助具１の挿入管体２内に挿入
しておいてから、第２図で示すように口腔より挿
入補助具１を体腔内に挿入する。このとき、マウ
スピース４のストツパねじ５をゆるめ、挿入管体
２の挿入長さを調節するとともに、適切な位置に
おいてストツパねじ５を締め付けて固定する。し
たがつて、患者に応じて挿入管体２を挿入設置す
ることができる。 First, the flexible insertion part 13 of the endoscope 12 is inserted through the insertion port body 3 into the insertion tube body 2 of the insertion aid 1, and then the insertion aid is inserted into the oral cavity as shown in FIG. 1 into the body cavity. At this time, the stopper screw 5 of the mouthpiece 4 is loosened to adjust the insertion length of the insertion tube 2, and the stopper screw 5 is tightened and fixed at an appropriate position. Therefore, the insertion tube body 2 can be inserted and installed depending on the patient.
そして、この状態において先端側部分６より柔
らかい後端側部分７は咽喉および食道内に位置す

腔である咽喉および食道には柔らかい後端側部分
７が当るため、患者の負担を軽減できる。しか
も、患者にとりその頭部および首の動きが比較的
拘束されることが少ないので、さらに患者の負担
を軽減できるのである。 In this state, the rear end portion 7, which is softer than the distal end portion 6, is located in the throat and esophagus. In other words, the soft rear end portion 7 comes into contact with the throat and esophagus, which are the lumens that are most likely to cause strain on the patient, so that the burden on the patient can be reduced. Moreover, since the movement of the patient's head and neck is relatively less restricted, the burden on the patient can be further reduced.
なお、本考案における挿入管体２の構成は上記
実施例のものに限定されるものではない。たとえ

することができる。 Note that the configuration of the insertion tube body 2 in the present invention is not limited to that of the above embodiment. For example, it may be configured as shown in FIG. 4 or FIG. 5. That is, the structure shown in FIG. 4 is characterized in that the outer periphery of the distal end portion 15 of a single flexible tubular member 14 is covered with another flexible tubular member 16. Therefore, the rear end side portion 17 of the insertion tube body 2
can be made to have a lower hardness than the distal end portion 15, that is, to be softer.

る。 In addition, in the case shown in FIG. 5, the insertion tube body 2 is constituted by a single flexible tubular member 18 made of a soft synthetic resin, for example, a polyurethane resin, and a portion corresponding to the distal end side portion 19 is It is cured by applying heat. In other words, the hardness of the unheated rear end portion 20 is relatively lower than that of the front end portion 19, that is, it is made soft.

で、さらに患者の負担を軽減できる。 As explained above, in the present invention, the rear end portion of the flexible insertion tube is formed to have a lower hardness than the distal end portion, so that the burden on the patient during use can be reduced. For example, when inserting from the oral cavity through the throat and esophagus deep into the body cavity,
Since the soft rear end portion of the insertion tube body is located in the throat and esophagus where the burden is most likely to be felt, the burden on the patient can be reduced. Moreover, since the movement of the patient's head and neck is relatively less restricted, the burden on the patient can be further reduced.
