PROBLEM TO BE SOLVED: To provide a treatment instrument capable of easily expanding a covering material and expanding a large-size covering material, the treatment instrument to be used for attaching the covering material to an affected part in the body.SOLUTION: A treatment instrument 1 of the present invention includes a cylindrical body 2, a wire 3 retractably inserted into a hole 2a of the cylindrical body 2, and a rod material 6 connected to the tip end of the wire 3 and extending to the outside of the cylindrical body 2. A covering material H is disposed on facing side faces 60 and 61 of the rod material 6 such that, in a state where the wire 3 is retracted, the covering material H is bent along the tip end of the rod material 6, and the state where the covering material H is disposed on the side faces 60 and 61 of the rod material 6 is retained by an event that end portions Ha and Hb of the covering material H are clamped between the cylindrical body 2 and the rod material 6. When the wire 3 is made to advance, the rod material 6 advances along with the wire, so that the clamping of the end portions Ha and Hb of the covering material H is released. |
