用カプセルを体腔内の所定位置に長時間にわたり固定し
ておかなければならないことがある。For example, it is known that medical capsules are used to measure pH, temperature, pressure, etc. in body cavities, or to spray drugs. Depending on the purpose of use, the medical capsule may need to be fixed at a predetermined position within the body cavity for a long period of time.

セルを体壁に吸着させるようにする。As a means for fixing the medical capsule at a predetermined position within a body cavity, it has been considered to utilize suction force. That is, in this case, a cape is connected to the medical capsule, guided to the target area under X-ray fluoroscopy, and after the medical capsule is brought into close contact with the body wall at this area, the cape is connected to the cape and the cape is connected to the cape. The medical capsule is made to adhere to the body wall by creating a negative pressure through the capsule.

うことが困難となる。However, with this method, it may not be possible to bring the medical capsule into close contact with the body wall depending on the condition of the body wall, such as the hardness and degree of the core surface. Even if it is possible to reliably attach it, the adsorption state will be impaired due to body wall movement, etc., and it will fall off. Therefore, it is difficult to securely fix the medical capsule at a predetermined position within the body cavity for a long period of time to perform various measurements and achieve therapeutic purposes.

することかで角る。Next, a method of using the above medical capsule will be explained. First, the nine capsule bodies 1 are assembled as described above.
Once the capsule body 1 is inserted into the body cavity by having the patient swallow it, the capsule body 1 is set at a target site on the body wall 11 using an endoscope (not shown). Next, the thread-cutting forceps cut the thread-like member 16.16 exposed on the outer surface of the capsule body 1 using an electric heater (none of which is shown) through the treatment channel of the endoscope. As shown in the figure, the coils kdhxs, 1g, which were held in a compressed state by the bending force of the thread-like members 76 and 76, expand, and the ends of the pair of needle-like members 14 and 74 are caused by the biasing force of the coils 15 and 16. The side protrudes from the through hole 11.12 and sticks into the body wall 11, so that the capsule body l is fixed to the body @1r4r. Therefore, the capsule body I is
in the target area for a long time, that is, a pair of needle-like members 14゜1
4 can be identified until it dissolves, and during that time the pH in the body cavity can be continuously measured using the pH sensor 9.
また、一対の針状部材１４．１４の通孔１２゜１２かも
突出した部分け、これら通孔１１．１２が９０度以上の
逆ハの字状に傾斜している喪め。Also, the through holes 12.12 of the pair of needle-shaped members 14.14 also protrude, and these through holes 11.12 are inclined at an angle of 90 degrees or more in an inverted V-shape.

ル本体Ｉの固定が確実となる。The body intersects at an obtuse angle of 90 degrees or more according to this inclination angle
Since it sticks into the body wall 11, it does not come off from the body wall 11, and the fixation of the capsule body I is ensured.
ざらに、一対の針状部材１４．１４が所定時ｃ 間経
過後に溶けれは、カプセル本体１の固定状態が解除され

Ｉ６を交換することにょし、再利用することができる。Generally speaking, if the pair of needle-like members 14, 14 melts after a predetermined period of time c has passed, the fixed state of the capsule body 1 is released, so the capsule body 1 is recovered and the thread-like member 16°I6 is replaced. Of course, it can be reused.
第３図と第４図は薬剤散布用の医療用カプセルに適用し
九この発明の第２の実施例を示す。FIGS. 3 and 4 show a second embodiment of the present invention applied to a medical capsule for dispensing a drug.

One needle member 14 at one end of one coil spring 2J provided.
The other needle-like member 14 is biased at the other end.

互いに逆方向に回して両端部を結ぶようにした。Roughly speaking, in order to hold the pair of needle-like members 14 and 14 against the biasing force of the coiled spring 21, both ends of each needle-like member 1,
At the same time, a thread-like member II of jll is provided connected to the end @ of the first thread-like member 21, and a thread-like member ZS of [2] is provided by intertwining the middle part with this first thread-like member 21, and this second thread-like member 23 is connected to the upper cover J. After the capsule was led out of the capsule body 1 through the outflow hole 20, both ends were turned in opposite directions toward the center of the capsule body 1 to tie the two ends together.

If the thread-like member 23 is cut, the pair of needle-like members 14.14 will be inserted into the through hole 12. Because it protrudes from JX' and pierces the body wall 17,
The capsule body l can be fixed. Then, while the capsule body 1 is fixed, the outflow hole 2 of the upper cover 3 is
The medicine 18 continues to gradually flow out from the patient, and the affected area is treated.
また、カプセル本体１の回収、再利用や一対の針状部材

ることなく固定することができる。As described above, the present invention provides a needle-like member whose sharp portion is urged by the urging member in a direction to protrude outside the capsule body, and the needle-like member is moved by the urging member. Since we have provided a fixing means consisting of a thread-like member that holds the capsule body against the urging force of Since it sticks, the capsule body can be fixed. In other words, the needle-like member sticks into the body wall regardless of its hardness, flatness, etc.
The capsule body can be securely fixed without falling off due to body wall movement or the like.
