The intestinal device fixing device according to the present invention is a fixing device for surrounding and fixing a device provided in the intestinal tract for the purpose of protecting an anastomosis site after the excision operation of a tubular organ, and having a predetermined thickness. The body includes a band-shaped body having a width and a width, and the body is a biodegradable (water-absorbing) substance or a non-water-absorbing substance, which is made of a material that does not react with foreign substances in the human body, and has a low elongation in the longitudinal direction of the body. It is characterized in that both widthwise edges of the body are treated in a flexible form so as not to damage the outer surface of the intestine when contacting the outer surface of the intestine. According to the present invention, a strip-shaped fixing device for fixing a device provided in the intestinal tract outside the intestinal tract to protect the anastomosis site after the surgical operation of the tubular organ is less than 10% long. It has a high elongation rate, and both edges of the band have a flexible shape, and the instrument is fixed outside the organ with appropriate pressure to maintain the shape of the intestinal wall of the organ, but does not affect the organ ..本発明による腸管内器具固定装置は、管状の臓器の切除手術後、吻合部位保護のために腸管内に設けられる器具を腸管の外部で取り囲んで固定するための固定装置であって、所定の厚さ及び幅を有する帯状の胴体を含み、前記胴体は生分解性(吸水性)物質又は非吸水性物質で、人体内で異物反応がない素材から構成され、胴体の長手方向に低い伸び率を有し、胴体の幅方向の両縁端は、腸管の外表面に接触したとき、腸管の外表面に傷を付けないように柔軟な形態に処理されていることを特徴とする。このような本発明によれば、管状の臓器の切除手術後、吻合部位保護のために腸管内に設けられる器具を腸管の外部で取り囲んで固定するための帯状の固定装置が10%未満の長さ伸び率を有し、帯の両縁端が柔軟な形態になり、器具を臓器の外部で適当な圧力で固定して臓器の腸壁の形態を維持しながらも臓器には影響を与えなくなる。
