TREATMENT INSTRUMENT

PROBLEM TO BE SOLVED: To provide a treatment instrument used for sticking a covering material to an affected part in a body, facilitating work of spreading the covering material and capable of spreading a large-size covering material.SOLUTION: The treatment instrument 1 includes: a cylindrical body 2; wall bodies 3 and 4 protruding from an end face at one end of the cylindrical body 2; a wire 5 retractably inserted in the cylindrical body 2; a coupling support member 6 that is coupled and connected to the tip end of the wire 5; wing parts 7 and 8, one ends of which are rotatably journaled to the wall bodies 3 and 4 and include covering material arrangement surfaces 70 and 80 on which the covering material is placed; and transmission members 9 and 10, the one ends of which are rotatably journaled to the coupling support member 6 and the other ends of which are rotatably journaled to the other ends of the wing parts 7 and 8. When the wire 5 is retractingly/insertingly operated, the wing parts 7 and 8 rotate about the positions journaled by the wall bodies 3 and 4 via the coupling support member 6 and the transmission members 9 and 10. 【課題】体内の患部に被覆材を貼り付けるために使用される処置具であって、被覆材を広げる作業が容易であり、大きな寸法の被覆材を広げることが可能な処置具を提供する。【解決手段】本発明に係る処置具１は、筒体２と、筒体２の一端の端面から突出する壁体３，４と、筒体２内に進退自在に進退自在に挿通されたワイヤ５と、ワイヤ５の先端に連結固定された連結支持部材６と、壁体３，４に一端が回転自在に軸支されて、被覆材が配置される被覆材配置面７０，８０を備えた羽根部７，８と、一端が連結支持部材６に回転自在に軸支されて、他端が羽根部７，８の他端に回転自在に軸支される伝達部材９，１０とを備え、ワイヤ５を進退操作した場合には、連結支持部材６、伝達部材９，１０を介して、羽根部７，８が壁体３，４に軸支される位置を中心に回転するように構成されている。【選択図】図３
