Patent ID: 8652132

Claim:
A grasping treatment device comprising: a probe extending along a longitudinal axis; a sheath through which the probe is inserted so that the probe protrudes toward a distal direction; a jaw which is attached to a distal portion of the sheath rotatably around a rotation axis perpendicular to the longitudinal axis, and which is configured to open/close relative to a distal portion of the probe in open/close directions perpendicular to the longitudinal axis and perpendicular to the rotation axis; a fixing member which is provided between the probe and the sheath, and which is configured to fix a most-distal fixed position of the probe with respect to the sheath in a state that the fixing member prevents contact between the probe and the sheath, the most-distal fixed position of the probe being at a position where the probe is fixed with respect to the sheath on the most distal direction side in directions parallel to the longitudinal axis; and an attachment portion which attaches the jaw to the sheath in a state that the rotation axis of the jaw passes through the probe at the most-distal fixed position.
