摘要：
A treatment device includes a flexible sheath； a control wire that can move axially within the flexible sheath； a first treatment member connected to a distal end of the control wire； a second treatment member connected to a distal end of the first treatment member； and a protection member that covers the second treatment member depending on the mode of operation. When the treatment device is in a first treatment mode, the second treatment member projects from a distal end of the protection member. When the treatment device is in a second treatment mode, the first treatment member projects from the distal end of the flexible sheath, and the protection member covers the second treatment member.
