Abstract: A ventilation pipe sleeve system comprises a ventilation pipe sleeve, a first filter, and a cap attached to the ventilation pipe sleeve. The ventilation pipe sleeve includes a tubular body including an outer surface and an inner surface. The inner surface of the tubular body defines a conduit extending from a first end to a second end of the ventilation pipe sleeve. The first filter is liquid impermeable and is gas permeable, the first filter is fixed to the tubular body to form a watertight structure at a first end region of the tubular body. The cap covers the first filter and at least a portion of the outer surface of the tubular body.

Abstract: An endoscope includes an insertion portion, an operation portion, a moving member, a detent, a rod, a wire and a bearing. The insertion portion is configured for insertion into a subject, the insertion portion including an actuating mechanism. The operation portion, the moving member, the rod and the wire are translatable in conjunction with each other. The detent located distally relative to the moving member, and the detent is configured to prevent a distally forward translation of the moving member past the detent. The bearing is located distally relative to the moving member, the bearing including an opening having a contact surface. The rod extends through the opening and is in slidable contact with the contact surface, and the contact surface is made of resin.

Abstract: A treatment tool includes: an end effector configured to implement treatment of living tissue; an operation input portion configured to receive operation; a tubular portion provided along a longitudinal axis of the treatment tool, the tubular portion having a first end and a second end, the first end being connected to the end effector, the second end being provided with a first engagement portion; a driver configured to move along the longitudinal axis according to the operation on the operation input portion, the driver including a second engagement portion configured to engage with the first engagement portion; and a pusher configured to connect the tubular portion and the driver to each other by coming into contact with the tubular portion toward a central axis of the tubular portion in a state where the first engagement portion and the second engagement portion have engaged with each other.

Abstract: Treatment instrument includes an operation button for receiving a user operation provided in a housing. The housing has a pair of first surfaces spaced apart at predetermined intervals and a sliding portion of the operation button, provided with a curved second surface having a predetermined curvature, is located in the space between the pair of first surfaces and configured for rotation and to press a switch element in response to a user operation to affect an associated treatment operation.

Abstract: Ultrasonic treatment device includes a blade configured to apply ultrasonic vibrations to target tissue and a jaw movable relative to the blade between open and closed configurations. In some examples, the jaw includes a base having an inner channel and a plurality of slots in communication with the inner channel, and a pad having a plurality of protrusions, each protrusion configured to be received within a different slot of the plurality of slots. In further examples, the jaw includes a base having a pair of side walls defining an inner channel, one of the side walls including a rail member extending into the channel, and a pad having a single groove for receiving the rail member when the pad is positioned within the channel. A surface of the groove is configured to contact a surface of the rail when a force is applied against a grasping surface of the pad.

Abstract: An energy treatment instrument includes: a grip configured to be gripped by an operator; a transducer configured to generate ultrasound vibrations according to a supplied electric power; a first ultrasound terminal that is arranged in the transducer; a first high-frequency terminal that is arranged in the grip; and a base unit that is arranged in the grip. The base unit includes a second ultrasound terminal configured to electrically connect the first ultrasound terminal and a cable electrically connected to a control device outside the energy treatment instrument, by abutting on the first ultrasound terminal; and a second high-frequency terminal configured to electrically connect the first high-frequency terminal and a cable electrically connected to the control device outside the energy treatment instrument, by abutting on the first high-frequency terminal.

Abstract: An energy treatment tool includes: a grip to be held by an operator; a lever that is provided in a state of being exposed to an outside of the grip, the lever being configured to move in response to a changing operation by an operator, the changing operation being for changing an output state of energy; an electric switch that is arranged inside the grip the electric switch being configured to generate a signal for changing an output state of the energy; and a driver that is installed inside the grip such that the driver is rotatable about an axis intersecting an axis along a longitudinal axis correspondingly to movement of the lever, the driver being configured to switch the electric switch between a contacting state and a noncontacting state.
