PROBLEM TO BE SOLVED: To provide a treatment instrument for administering a covering material to an affected area inside a body without swelling of the covering material by absorbing moisture.SOLUTION: According to a treatment instrument 1 in this invention, a covering material H can be thrown in a space between flanges 4, 5 inside a cylindrical body 2 from an opening 2a of the cylindrical body 2 by operation of moving a wire 3 to a distal end side of the cylindrical body 2 to put out the flange 5 from the opening 2a at a distal end of the cylindrical body 2. Further, the covering material H can be retained inside the cylindrical body 2 with the covering material H tightly sealed by the flanges 4, 5 by operation of moving the wire 3 to a proximal end side of the cylindrical body 2 to arrange the flanges 4, 5 inside the cylindrical body 2. In addition, the covering material H thrown in the space between the flanges 4, 5 can be discharged outside the cylindrical body 2 by operation of moving the wire 3 to the distal end side of the cylindrical body 2 to put out a range between the flanges 4, 5 out of the opening 2a of the cylindrical body 2.SELECTED DRAWING: Figure 2 |
