Publication number: 20170186567Abstract: An operation input unit includes a board unit including a switch, and a base. An external force application portion moves by a button portion being pushed, and changes an open or closed state of the switch by varying an external force acting on the board unit in accordance with the movement. A board deflection portion forms a space between the board deflection portion and the base in a state that the button portion is not pushed, and deflects toward a movement direction of the external force application portion by the external force application portion moving by the pushing of the button portion.Type: ApplicationFiled: March 14, 2017Publication date: June 29, 2017Applicant: OLYMPUS CORPORATIONInventors: Hideo SANAI, Masami OSHIDA

Publication number: 20060235455Abstract: An ultrasonic trocar includes a handpiece unit, a dilator, and a tubular cannula. The handpiece unit includes an ultrasonic transducer and a probe. The handpiece unit forms a puncture hole in a somatic wall by a tip end of the probe with ultrasonic vibration transmitted to the probe tip end from the transducer. The dilator includes a tubular body and a sheath. The body portion has a dilating portion which expands the puncture hole of the body wall, and the probe is inserted through from a proximal end portion of the body portion. The sheath is arranged in a state of protruding from a distal end portion of the body portion, and covers the peripheral surface of the probe with the probe tip end remained. The cannula includes the dilator inserted therethrough and is kept retained to the puncture hole expanded by the expanding portion.Type: ApplicationFiled: June 15, 2006Publication date: October 19, 2006Inventor: Masami Oshida
