[Means for Solving the Problems]
The endoscope apparatus according to the present invention comprises an observation means provided at least on the tip side of a capsule-like container, an expanding / contracting balloon provided on the rear side of the observation means, a fluid inside the balloon or between the balloon and the capsule-like container. A capsule endoscope having a fluid inlet for injecting the fluid, and a flexible tube body for fluid supply detachable from the fluid inlet of the endoscope; An observation means provided on the tip side and an expanding / contracting balloon provided on the rear side of the observation means, and a tube for sending fluid to a fluid inlet for injecting fluid in the balloon or between the balloon and the capsule-like container The tip of the body is pierced to connect the tube body and the capsule endoscope, and with the balloon contracted, the capsule endoscope is swallowed, and the balloon is inflated at any point in the body cavity. Then, the balloon is fixed to the wall of the body cavity by frictional force, and then the connection between the tube body and the capsule endoscope is released, leaving the capsule endoscope in a state where the balloon is expanded in the body cavity, leaving only the tube body outside Pull out.
また、前記流体注入口は、前記チューブ体の先端部を突き刺すことによりバルーン内またはバルーンとカプセル状容器の間に流体を注入でき、チューブ体の先端を抜いた時には密閉して、内部の流体が抜け出ない構造にすることにより、上記構成の場合と同様にチューブ体とカプセル内視鏡が連結され、バルーンを収縮させた状態でカプセル内視鏡とは別体の内視鏡の処置具チャンネル内にチューブ体を挿入し、内視鏡と共にカプセル内視鏡を飲込み、内視鏡をガイドに体腔内の任意の箇所までカプセル内視鏡を運んだ後、バルーンを膨張させてからチューブ体とカプセル内視鏡の連結を解除し、バルーンが膨張した状態のカプセル内視鏡を残して、チューブ体および内視鏡を体外に抜き取ることも可能である。カプセル内視鏡を目的部位へ早く運びたい時には有効な手段である。
さらに本発明の内視鏡離脱方法は、請求項１から３のいずれかに記載の内視鏡装置において、前記チューブ体と連結された前記カプセル内視鏡を体腔内の任意の箇所で離脱させる方法であって、収縮させた状態のバルーンを膨張させるステップと、チューブ体とカプセル内視鏡の連結を解除するステップと、バルーンが膨張した状態のカプセル内視鏡を残してチューブ体のみを抜き取るステップと、を有することを特徴とする。
In addition, the fluid inlet can inject a fluid into the balloon or between the balloon and the capsule-like container by piercing the tip of the tube body, and the fluid inlet is sealed when the tip of the tube body is pulled out. By making the structure so as not to come out, the tube body and the capsule endoscope are connected as in the case of the above configuration, and in the treatment tool channel of the endoscope separate from the capsule endoscope in the state where the balloon is contracted. The tube body is inserted into the body, the capsule endoscope is swallowed with the endoscope, and after the capsule endoscope is transported to an arbitrary position in the body cavity with the endoscope as a guide, the balloon is expanded and then the tube body and the It is also possible to withdraw the tube body and the endoscope from the body leaving the capsule endoscope uncoupled and leaving the capsule endoscope with the balloon inflated. It is an effective means when it is desired to quickly carry the capsule endoscope to the target site.
Furthermore, according to the endoscope detachment method of the present invention, in the endoscope apparatus according to any one of claims 1 to 3, the capsule endoscope coupled with the tube body is detached at any position in a body cavity. A method comprising: inflating a balloon in a deflated state; disengaging a tube body from a capsule endoscope; removing only the tube body leaving a capsule endoscope in a state where the balloon is inflated. And providing a step.
本実施の形態は以下の効果を有する。
カプセル内視鏡２Ｃとチューブ体３Ｃの連結を解除した時には、針状細径部１１が二重管の外筒２８内に収納される構造をしているので、チューブ体３Ｃを抜去する時に針状部材により体腔内壁を誤って損傷するようなことはない。また、針状細径部１１を外筒２８内に収納しながら引く抜くことで、バルーン７を体腔内壁に密着させなくても連結が容易に解除できる。
略する。
The present embodiment has the following effects.
When releasing the coupling of the capsule endoscope 2C and the tube body 3 C is, since a structure in which needle-shaped small-diameter portion 11 is housed in the outer tube 28 of the double pipe, when removing the tube body 3C The needle-like member does not accidentally damage the internal cavity wall. Further, by retracting the needle-like small diameter portion 11 while storing it in the outer cylinder 28, the connection can be easily released without bringing the balloon 7 into close contact with the body cavity wall.
I will abbreviate.
