    Abstract: The disclosed technology is directed to a probe unit of an ultrasonic treatment tool that comprises an ultrasonic probe having respective opposed distal and proximal end sides in a longitudinal direction and configured to transmit ultrasonic vibrations. A treatment portion is attached to the distal end side of the ultrasonic probe in the longitudinal direction. The treatment portion includes a cutting surface of a shape having directionality. A handle portion having a cutting portion identifier that is engaged with an outer circumference of the proximal end side of the ultrasonic probe. The cutting portion identifier is configured to indicate a position of a reference side representing a direction in which the cutting surface is oriented and/or included in the cutting surface.

    Abstract: In an endoscope including a rear grasping portion extending along a second longitudinal axis that is a direction flexed relative to a first longitudinal axis along which the operation portion body extends, a bend preventing portion covering a universal cable extending out from the proximal end side of the rear grasping portion is joined to the proximal end side of the rear grasping portion via a movable joint portion so that a direction of the bend preventing portion can be changed by the movable joint portion to a first direction oriented to the inner side in the flexion direction of the rear grasping portion relative to the operation portion body and a second direction oriented to the outer side in the flexion direction of the rear grasping portion relative to operation portion body.
