20090192388 | ULTRASONIC TRANSMISSION MEMBER - An ultrasonic transmission member including one end part and the other end part and transmitting an ultrasonic wave input into the one end part to the other end part is formed by preparing a main mold having a casting cavity corresponding to a whole outer shape of the ultrasonic transmission member, melting an alloy which is a material of a metallic glass, and pouring the melted alloy into the casting cavity of the main mold to solidify the melted alloy in a liquid phase state thereof. | 07-30-2009 |
20090193898 | ULTRASONIC WAVE VIBRATING APPARATUS - An ultrasonic wave vibrating apparatus includes a passive element converting electric energy to ultrasonic vibration, electrodes, a horn body arranged in a forward side of the element and amplifying the vibration, a backing arranged in the base side of the element and backing the element, and a horn connecting portion having one end connected to the body and the other end connected to the backing to connect the body and the backing to each other with the element sandwiched between the body and the backing. At least one of the body, the connecting portion and the backing is formed of metallic glass. The body and the connecting portion can be formed of the metallic glass integrally with each other. A cover covering the element may be included, and the cover, the body and the connecting portion can be formed of the metallic glass integrally with each other. | 08-06-2009 |
20090216157 | ULTRASONIC OPERATING APPARATUS - An ultrasonic treatment instrument is provided with an ultrasonic transducer, a probe portion to which ultrasonic wave outputted from the ultrasonic transducer is transmitted, a sheath portion into which the probe portion is inserted detachably, the sheath portion including at a distal end portion thereof, a grasping member rotatably supported so as to face the probe portion, and a handle portion coupled to a proximal end portion of the sheath portion detachably and operating the grasping member such that the grasping member is opened and closed to the probe portion, where the distal end portion of the probe portion includes a cavitation production portion where the distal end portion of the probe portion has, on a face thereof facing the grasping member, a flat face extending so as to intersect a vibration direction of the ultrasonic vibration, and cavitation is produced by the flat face in a state that a body tissue has been grasped between the grasping member and the distal end portion of the probe portion. | 08-27-2009 |
20100057117 | ULTRASONIC OPERATING APPARATUS - In an ultrasonic operating apparatus which is provided with an insertion portion including a sheath having a distal end and a proximal end and formed of a cylindrical body having at least partially flexibility and a procedure portion disposed at the distal end of the sheath and performing a procedure for resection of a body tissue, and an operation portion disposed at the proximal end of the sheath and operating the procedure portion, the procedure portion is provided with an ultrasonic transducer unit including an ultrasonic transducer generating ultrasonic vibration, a probe portion integrally coupled with the ultrasonic transducer and transmitted with ultrasonic waves output from the ultrasonic transducer, and a casing accommodating the ultrasonic transducer, a jaw caused to face the probe portion which configures a distal end of the ultrasonic transducer and including a supporting point held in a state that the supporting point is not moved to the probe portion axially relative to the probe portion and an operating point movable axially relative to the probe portion, the jaw being driven to be opened and closed to the probe portion, a cover member coupled to the distal end of the sheath and rotatably supporting the operating point of the jaw, and a supporting portion disposed at a distal end of the casing and supporting the supporting point of the jaw, the operation portion is provided with a movable handle moving the operating point of the jaw axially relative to the probe member via the sheath and the cover member and rotating the jaw about the supporting point to drive the jaw to be opened and closed to the probe portion, and the jaw is set in a state that the operating point and the supporting point are positioned on a line orthogonal to a center line of the probe portion in a state that the jaw has been closed to the probe portion. | 03-04-2010 |
20120330195 | PROBE ADAPTED TO TREAT LIVING TISSUE AND ACTUATION METHOD OF DEVICE - A probe which is configured for a treatment device which is configured to treat a body tissue using ultrasonic vibration, includes a base member which includes a base surface defined by a longitudinal direction and a width direction shorter than the longitudinal direction and which is a vibration-retardation member configured to hardly transmit the ultrasonic vibration, a waveguide main body which has a width smaller than a width of the base surface in a width direction, protrudes with respect to the base surface, and is extended along the longitudinal direction of the base surface, and an end effecter which is provided at a tip end portion of the waveguide main body and which is configured to treat the body tissue by the ultrasonic vibration transmitted through the waveguide main body. | 12-27-2012 |
20130060169 | MEDICAL APPARATUS - A treatment apparatus includes an ultrasonic vibration source, an ultrasonic treatment portion which is configured to treat living tissue by ultrasonic vibration transmitted from the ultrasonic vibration source, and a micrograin feeder which is configured to supply liquid containing micrograins to between the ultrasonic treatment portion and the living tissue. Whole micrograins within the micrograin-containing solution has a grain size equal to or smaller than an amplitude of the ultrasonic vibration. | 03-07-2013 |
20140350540 | HIGH-FREQUENCY ELECTROSURGICAL TREATMENT INSTRUMENT FOR OPERATIONS AND HIGH-FREQUENCY ELECTROSURGICAL SYSTEM FOR OPERATIONS - A high-frequency electrosurgical treatment instrument for operations, includes a pair of forceps pieces, an insulating member, a transmission member, a manipulation rod member, a distal end cover member, a shaft member and a manipulation portion. The instrument, includes a flow channel portion formed between the manipulation rod member and the shaft member, the flow channel portion being disposed along a longitudinal direction of the manipulation rod member to allow liquid to flow; a groove portion that communicates with the flow channel portion to allow the liquid to flow from the flow channel portion; and an opening portion that communicates with the groove portion to supply the liquid near the proximal end portions of the pair of forceps pieces. | 11-27-2014 |
20140378971 | TREATMENT DEVICE - A treatment device includes a first grip member having an elongated shape, and a second grip member which is displaced with respect to the first grip member to grip the biological tissue between the first grip member and the second grip member. The second grip member includes a grip section that comes into contact with a biological tissue as a gripping target. I/A | 12-25-2014 |
