PROBLEM TO BE SOLVED: To provide a body pasting treatment instrument of a patch sheet, which can introduce a patch sheet into a body, and paste the patch sheet to an affected part of a body, by developing the patch sheet surely.SOLUTION: A body pasting treatment instrument 10 is used for introducing a patch sheet S patched to an affected part of a body, and developing the patch sheet, and comprises: two laminated film sheets 111, 111； and a tubular element 12 having a lumen, and whose tip end part is inserted between the film sheets 111, 111. By sealing outer peripheral edges of the film sheets 111, 111, a bag member 11 which has a gap 112 which can fluid communicate with only a lumen of the tubular element 12, is formed between the film sheets, the bag member 11 has a pocket part 113 which can store the patch sheet between the folded film sheets, by a configuration in which, an end part opposite to an end part into which a tip end part of the tubular element 12 is inserted, is folded so that, external surfaces of respective film sheets 111, 111 are folded to inside so as to face each other.SELECTED DRAWING: Figure 1【課題】貼付シートを体内に導入して体内の患部に確実に展開して貼付することができる貼付シートの体内貼付処置具を提供する。【解決手段】 体内貼付処置具１０は、体内の患部に貼付される貼付シートＳを体内へ導入し展開するためのものであって、２枚の重なるフィルムシート１１１、１１１と、内腔を有し、フィルムシート１１１、１１１の間に先端部が挿入される管状部材１２とを備え、フィルムシート１１１，１１１の外周縁が封止されることにより、フィルムシートの間に管状部材１２の内腔のみと流体連通可能な隙間１１２を有する袋部材１１が形成され、袋部材１１は、管状部材１２の先端部が挿入される側の端部と反対側の端部が、前記の各フィルムシート１１１、１１１の外面が内向きとなって対向するように内側に折り込まれることにより、折り込まれたフィルムシート間に貼付シートの収容が可能なポケット部１１３が形成されている。【選択図】図１
