Abstract: A thrombus aspiration catheter is disclosed which can shear a thrombus and efficiently aspirate the thrombus. When the pressure of the inside of an inner tube is made negative, an outer tube is rotated around an axis relative to the inner tube, and an inner opening portion and an outer opening portion are positioned at an open position at which the inner opening portion and the outer opening portion overlap each other, a thrombus enters the inside of the inner tube through the inner opening portion and the outer opening portion. When the outer tube is further rotated up to a closed position at which the whole outer opening portion does not overlap the inner opening portion, the thrombus is sheared by an edge portion of the inner opening portion and an edge portion of the outer opening portion and into the inside of the inner tube.

Abstract: According to one embodiment, a checkout apparatus includes an apparatus body, a monitor, a rotation mechanism, a lock mechanism, a notification unit, and a control unit. The apparatus body can switch a mode for checkout processing between a cashier mode in which a cashier operates the apparatus and a self-service mode in which a customer operates the apparatus. The monitor is provided on the apparatus body and displays a status of the checkout processing. The rotation mechanism rotates the apparatus body. The lock mechanism locks the rotation of the rotation mechanism at least at two positions. The notification unit causes the monitor to display guidance showing a procedure for mode switching, including locking and unlocking by the lock mechanism. The control unit switches checkout processing modes in response to that the rotation of the rotation mechanism is stopped at one of the positions with the locking by the lock mechanism.
