Description

この発明は、内視鏡の挿入を容易にする自動移動式の内視鏡挿入機に関するものである。  The present invention relates to an automatically moving endoscope insertion machine that facilitates insertion of an endoscope.

従来より内視鏡ファイバーの腸管の奥への挿入は困難を要し、胃内視鏡ファイバーにおいては十二指腸までの挿入が限度であり、又、大腸内視鏡ファイバーにおける挿入は挿入手技そのものが熟練の医師ですら時間を要し、患者に少なからず苦痛を強いるものとなっていて、一般的な大腸内視鏡ファイバーを用いた小腸の奥までの挿入は不可能であり、挿入時に患者に苦痛を生じる理由は大腸内視鏡ファイバーをある程度の力で外から押したり、引っ張ったりしなければ奥へは進めない部位が少なからず存在するからであり、外から加える力が大腸内視鏡ファイバーの先端に伝えずらい事が原因となっている。又、近年ダブルバルーン式のファイバーが開発され小腸までの観察が可能となっているが、やはり外から押したり引っ張ったりする作業が主体であり、先端に力が伝えずらい状態は改善されておらず一般の内視鏡カメラ検査より遥かに長い時間と苦痛を患者に強いるものとなっていて、操作が煩雑で、外からの外力をかなり要し、ファイバーの進行に難渋している。  Conventionally, it has been difficult to insert an endoscope fiber into the back of the intestinal tract, and insertion of gastroscope fiber up to the duodenum is limited. Even doctors take time, and it is not a little painful for the patient, and it is impossible to insert into the back of the small intestine using a general colonoscopy fiber. This is because there are not a few parts that cannot be advanced to the back unless the colonoscopy fiber is pushed or pulled from the outside with a certain amount of force. It is caused by things that are difficult to convey to the tip. In recent years, double-balloon fibers have been developed, and observation up to the small intestine is possible. However, the main task is to push and pull from the outside. First of all, the patient is forced to take much longer time and pain than a general endoscopic camera inspection, and the operation is complicated, and external force from outside is considerably required, and the progress of the fiber is difficult.

発明が解決しようとする課題Problems to be solved by the invention

この発明は内視鏡の挿入手技を内視鏡ファイバーを自動的に奥へ移動させてゆく事で容易とすると共に、内視鏡ファイバーをそのまま使い、小腸の奥までの挿入を可能とする事を目的とする。又、発明の構造は外部より内部が遮断された状態とし内部構造の衛生を保てるものとする。  This invention facilitates the insertion procedure of the endoscope by automatically moving the endoscope fiber to the back, and enables the insertion to the back of the small intestine using the endoscope fiber as it is. With the goal. In addition, the structure of the invention is such that the inside is shut off from the outside, and the hygiene of the internal structure is maintained.

課題を解決するための手段Means for solving the problem

この課題を解決するための請求項１の発明は内筒１２の後方に後方バルーン４を備えた後方空洞バルーン台３を取り付け、内筒１２の壁面に空気注入チューブ１を埋め込み、後方空洞バルーン台３に空気流入孔２を設け、内側伸展円筒６と外側伸展円筒７、さらに前方バルーン１０を備えた移動空洞バルーンリング９及び後方空洞バルーン台３で周囲を密閉する形態で伸展円筒空洞部８を形成し、前方方向圧力弁５、後方方向圧力弁１３のみが空気の出入可能な部位とし、前方壁１４と移動空洞バルーンリング９を繋ぐ形で伸展収縮外套１１を設け内部を完全に外部より遮断する形態としたもので、空気注入チューブ１に陽圧で空気を送り込むと、空洞バルーン台３の空洞部の空気圧が上昇し後方バルーン４が拡張し、後方空洞バルーン台３に取り付けた前方方向圧力弁５が開き伸展円筒空洞部８へと空気が流入し内側伸展円筒６と外側伸展円筒７が伸展する事で移動空洞バルーンリング９が前方へ移動する。次いで移動空洞バルーンリング９に取り付けてある前方方向圧力弁５が空気圧で開き、前方バルーン１０が拡張する。逆に空気注入チューブ１より陰圧で空気を抜いてゆくと、まず後方バルーン４が縮小し、次いで後方方向圧力弁１３が開き伸展円筒空洞部８から空気が流出し内側伸展円筒６と外側伸展円筒７が収縮する事で移動空洞バルーンリング９が後方へ移動する。さらに陰圧で空気が抜かれると移動空洞バルーンリング９に取り付けてある後方方向圧力弁１３が開き前方バルーン１０が縮小する。この一連の運動を繰り返す事で本発明を前進させる事ができ、内筒１２の内側に内視鏡ファイバーを固定する事で内視鏡ファイバーを腸管の奥へと進めてゆく事ができる。前方方向圧力弁５は後方の空気圧が一定の圧以上となると前方方向へのみに空気が流出する弁であり、後方への空気の流れは遮断する弁である。後方方向圧力弁１３は前方の空気圧が一定の圧以上となると後方方向へのみに空気が流出する弁であり、前方への空気の流れは遮断する弁である。  In order to solve this problem, the invention according to claim 1 is such that a rear cavity balloon base 3 having a rear balloon 4 is attached to the rear of the inner cylinder 12, the air injection tube 1 is embedded in the wall surface of the inner cylinder 12, and the rear cavity balloon base is provided. 3 is provided with an air inflow hole 2, and an extending cylindrical cavity 8 is formed in such a manner that the periphery is sealed with a moving cavity balloon ring 9 having a front balloon 10 and a rear cavity balloon base 3. The front pressure valve 5 and the rear pressure valve 13 are formed so that only the air can enter and exit, and the expansion and contraction mantle 11 is provided to connect the front wall 14 and the moving cavity balloon ring 9 to completely shut the inside from the outside. When air is fed into the air injection tube 1 with positive pressure, the air pressure in the cavity of the cavity balloon base 3 rises and the rear balloon 4 expands, and the rear cavity balloon base 3 Moving the cavity by the forward direction the pressure valve 5 opens extended cylindrical hollow portion 8 attached and the air flows inside the extension cylinder 6 outer extension cylinder 7 is extended balloon ring 9 moves forward. The forward pressure valve 5 attached to the moving cavity balloon ring 9 is then opened pneumatically and the forward balloon 10 is expanded. On the contrary, when the air is drawn out from the air injection tube 1 by the negative pressure, the rear balloon 4 is first contracted, then the rearward pressure valve 13 is opened, and the air flows out from the extension cylinder cavity 8 so that the inner extension cylinder 6 and the outer extension are extended. As the cylinder 7 contracts, the moving cavity balloon ring 9 moves backward. Further, when air is extracted by negative pressure, the rearward pressure valve 13 attached to the moving cavity balloon ring 9 is opened and the front balloon 10 is contracted. By repeating this series of movements, the present invention can be advanced, and by fixing the endoscope fiber inside the inner cylinder 12, the endoscope fiber can be advanced to the back of the intestinal tract. The forward pressure valve 5 is a valve that allows air to flow out only in the forward direction when the rear air pressure exceeds a certain pressure, and blocks the flow of air in the rear. The rearward pressure valve 13 is a valve through which air flows out only in the rearward direction when the front air pressure exceeds a certain pressure, and the forward airflow is blocked.

請求項２の発明は内筒１２の後方外側に内筒１２を螺旋状に取り巻く様に螺旋型空気注入チューブ１６を空気注入チューブ１と前方バルーン１０を備えた移動空洞バルーンリング９を連結させる形で取り付け、内側伸展円筒６と外側伸展円筒７、さらに移動空洞バルーンリング９及び前方壁１４で周囲を密閉する形態で伸展円筒空洞部８を形成し、移動空洞バルーンリング９に取り付けた前方方向圧力弁５、後方方向圧力弁１３のみが空気の出入可能な部位とし、後方壁１５と移動空洞バルーンリング９を繋ぐ形で伸展収縮外套１１を設け内部を完全に外部より遮断する形態としたもので、空気注入チューブ１に陽圧で空気を送り込むと、螺旋型空気注入チューブ１６より移動空洞バルーンリング９へ空気が注入されてゆき前方バルーン１０が拡張し、次いで前方方向圧力弁５が開き伸展円筒空洞部８へと空気が流入し内側伸展円筒６と外側伸展円筒７が空気圧により伸展する事で移動空洞バルーンリング９が後方へ移動する。逆に空気注入チューブ１より陰圧で空気を抜いてゆくと、まず前方バルーン１０が縮小し、次いで移動空洞バルーンリング９に取り付けた後方方向圧力弁１３が開き伸展円筒空洞部８から空気が流出し内側伸展円筒６と外側伸展円筒７が収縮する事で移動空洞バルーンリング９が前方へ移動する。この一連の運動を繰り返す事で本発明を前進させる事ができ、内筒１２の内側に内視鏡ファイバーを固定する事で内視鏡ファイバーを腸管の奥へと進めてゆく事ができる。  In the invention of claim 2, a spiral air injection tube 16 is connected to a moving cavity balloon ring 9 provided with an air injection tube 1 and a front balloon 10 so as to surround the inner cylinder 12 in a spiral manner outside the inner cylinder 12. The extension cylinder cavity portion 8 is formed in such a manner that the periphery is sealed by the inner extension cylinder 6 and the outer extension cylinder 7, the moving cavity balloon ring 9 and the front wall 14, and the forward pressure attached to the movement cavity balloon ring 9 is Only the valve 5 and the rearward pressure valve 13 are used as a part where air can enter and exit, and an extension / shrink mantle 11 is provided to connect the rear wall 15 and the moving cavity balloon ring 9 so that the inside is completely blocked from the outside. When air is fed into the air injection tube 1 at a positive pressure, air is injected from the spiral air injection tube 16 into the moving cavity balloon ring 9 and the forward balloon 10 Expanded, then it moves cavity balloon ring 9 in that a forward direction pressure valve 5 is air flows into the extension cylindrical cavity 8 opening inner extension cylinder 6 and the outer extension cylinder 7 is extended by the air pressure to move backward. On the other hand, when the air is extracted from the air injection tube 1 with negative pressure, the front balloon 10 first shrinks, and then the rearward pressure valve 13 attached to the moving cavity balloon ring 9 opens to allow air to flow out from the extended cylindrical cavity 8. When the inner extension cylinder 6 and the outer extension cylinder 7 contract, the moving cavity balloon ring 9 moves forward. By repeating this series of movements, the present invention can be advanced, and by fixing the endoscope fiber inside the inner cylinder 12, the endoscope fiber can be advanced to the back of the intestinal tract.

発明の効果The invention's effect

本発明はこの様な形態であるから、内視鏡ファイバーを自動的に腸管の奥へ進めてゆく事ができ、内視鏡ファイバーの挿入手技を容易とし、内視鏡ファイバーを用いそのまま小腸の奥までの挿入を可能にできる。又、内部は外部から完全に遮断された状態で清潔に保つ事が出来、本発明に関する内視鏡ファイバーは従来の内視鏡ファイバーと同様に洗浄して使用する事が出来る。  Since the present invention has such a configuration, the endoscope fiber can be automatically advanced to the back of the intestinal tract, facilitating the insertion procedure of the endoscope fiber, and using the endoscope fiber as it is, Insertion to the back is possible. Further, the inside can be kept clean while being completely cut off from the outside, and the endoscope fiber according to the present invention can be washed and used in the same manner as a conventional endoscope fiber.

図１は本発明の平面断面図であり、空気注入チューブ１に陽圧で空気を送り込むと、空気流入孔２より後方空洞バルーン台３へ空気が注入されてゆく事により空洞バルーン台３の空洞部の空気圧が上昇し後方バルーン４が拡張し、空気圧が一定の値を上回ると後方空洞バルーン台３に取り付けた前方方向圧力弁５が開き伸展円筒空洞部８へと空気が流入し内側伸展円筒６と外側伸展円筒７が空気圧により伸展する事で移動空洞バルーンリング９が前方へ移動する。伸展円筒空洞部８の空気圧が一定の値を上回ると移動空洞バルーンリング９に取り付けてある前方方向圧力弁５が開き移動空洞バルーンリング９に空気が流入し前方バルーン１０が拡張する。逆に空気注入チューブ１より陰圧で空気を抜いてゆくと、まず空洞バルーン台３の空洞部の空気圧が陰圧となり後方バルーン４が縮小し、空気圧が一定の陰圧を下回ると後方空洞バルーン台３に取り付けた後方方向圧力弁１３が開き伸展円筒空洞部８から空気が流出し内側伸展円筒６と外側伸展円筒７が収縮する事で移動空洞バルーンリング９が後方へ移動する。伸展円筒空洞部８の空気圧が一定の陰圧を下回ると移動空洞バルーンリング９に取り付けてある後方方向圧力弁１３が開き移動空洞バルーンリング９より空気が流出し前方バルーンが縮小する。この一連の運動を繰り返す事で本発明を前進させる事ができ、内筒１２の内側に内視鏡ファイバーを固定する事で内視鏡ファイバーを腸管の奥へと進めてゆく事ができる。  FIG. 1 is a plan sectional view of the present invention. When air is fed into an air injection tube 1 at a positive pressure, air is injected into the rear cavity balloon table 3 from the air inlet hole 2, whereby the cavity of the cavity balloon table 3 When the air pressure of the part rises and the rear balloon 4 expands, and the air pressure exceeds a certain value, the forward pressure valve 5 attached to the rear cavity balloon base 3 opens and air flows into the extension cylinder cavity part 8 and the inner extension cylinder The moving hollow balloon ring 9 moves forward as the outer cylinder 6 and the outer cylinder 7 extend by air pressure. When the air pressure in the extension cylindrical cavity 8 exceeds a certain value, the forward pressure valve 5 attached to the moving cavity balloon ring 9 opens and air flows into the moving cavity balloon ring 9 to expand the front balloon 10. Conversely, when air is extracted from the air injection tube 1 with negative pressure, the air pressure in the cavity portion of the hollow balloon base 3 becomes negative pressure first, and the rear balloon 4 contracts. When the air pressure falls below a certain negative pressure, the rear hollow balloon The rearward pressure valve 13 attached to the table 3 is opened, air flows out from the extension cylinder cavity 8 and the inner extension cylinder 6 and the outer extension cylinder 7 contract, whereby the moving cavity balloon ring 9 moves rearward. When the air pressure in the extension cylindrical cavity 8 falls below a certain negative pressure, the backward pressure valve 13 attached to the moving cavity balloon ring 9 opens and air flows out of the moving cavity balloon ring 9 and the front balloon shrinks. By repeating this series of movements, the present invention can be advanced, and by fixing the endoscope fiber inside the inner cylinder 12, the endoscope fiber can be advanced to the back of the intestinal tract.

When air is fed into the air injection tube 1 at a positive pressure, air is injected from the spiral air injection tube 16 into the moving cavity balloon ring 9 and forward balloons. 10 expands. When the air pressure exceeds a certain value, the forward pressure valve 5 attached to the moving cavity balloon ring 9 opens, and air flows into the extension cylinder cavity 8 and the inner extension cylinder 6 and the outer extension cylinder 7 extend by air pressure. The moving cavity balloon ring 9 moves backward. Conversely, when air is extracted from the air injection tube 1 with negative pressure, the air pressure in the cavity of the moving cavity balloon ring 9 first becomes negative pressure, and the front balloon 10 contracts. When the air pressure falls below a certain negative pressure, the moving cavity The rearward pressure valve 13 attached to the balloon ring 9 is opened, air flows out from the extension cylinder cavity 8 and the inner extension cylinder 6 and the outer extension cylinder 7 contract, so that the moving cavity balloon ring 9 moves forward.
