Abstract
An energy and/or ultrasonic wave treatment device includes a sheath including a hollow portion and having a central axis along which the sheath extends; a probe inserted into the hollow portion; a fixed handle provided at a proximal end of the sheath; a movable handle configured to move relative to the fixed handle; a jaw provided at a distal end of the movable handle; a metal member provided at a position including a rotation axis; and a preventing member which prevents the metal member from falling out from its position. The jaw has a jaw side hole portion centered on the rotation axis, the sheath has a sheath side hole portion centered on the rotation axis, and a diameter of the jaw side hole portion on an outer surface of the jaw away from the sheath is larger than a diameter of the sheath side hole portion.
