<p>This treatment tool (1) for medical use comprises a treatment part (10), an operation member (20) the leading end of which is connected to the base end section of the treatment part (10) and at least one portion of which is flexible, and a flexible sheath (30) into which the operation member (20) penetrates so as to be retractable in the longitudinal direction. The operation part (20) is formed so that a range thereof of a prescribed length from the end is a hard section (20A) having a higher rigidity than other sections. A connection section (17) between the treatment part (10) and the operation member (20) is located outside the sheath (30) when the operation member (20) is in its most retracted state. The length of the hard section (20A) is such that when the operation part (20) is in its most advanced state other regions of the operation part are not exposed outside of the sheath (30).</p> |
