Abstract: A surgical instrument for fastening together opposing portions of a body organ. The instrument comprises a first support for supporting the first opposing portion of the body organ, a second support opposing the first support, for supporting the second opposing portion of the body organ, and a displacement-preventing member connected to the first or second support for preventing the supports from displacing relative to each other. The member comprises a pin protruding from one of the supports and a hole formed in the other of the supports. The pin is made of thermoplastic resin. When heated, the pin is softened and deformed, whereby the first and second supports are secured to each other, fastening together the opposing portions of the body organ.

Abstract: An ultrasonic diagnosis and treatment system having a thin tube which is capable of being inserted into a body cavity, and which has at its extreme end an observing ultrasonic vibrator for emitting ultrasonic waves for observation and a treating ultrasonic vibrator for emitting strong ultrasonic waves for treatment. Observation and treatment are performed by using ultrasonic wave. The system further includes a processing device for performing an operation other than the ultrasonic treatment at least on a region observed by using ultrasonic waves. A guide for enabling the processing device to reach the region observed by using ultrasonic waves is provided on the thin tube.

Abstract: A cleaning tube apparatus for an endoscope, comprises the endoscope having an observation optical system for observing a subject part at a forward-end portion, a cleaning tube detachable with respect to said endoscope, said cleaning tube being provided with a plurality of fluid jetting openings in a peripheral direction at one end of said cleaning tube, said fluid jetting openings being provided for leading cleaning fluid at least to said observation optical system, and a fluid supply unit connected to said cleaning tube, for supplying the cleaning fluid to said cleaning tube.

Abstract: A surgical device for stapling and fastening body tissues, comprises an insertion section extending from an operation section for insertion into a body cavity, stapling member connected to a distal end of the insertion section, for treating body tissues with a high-frequency current within a body cavity. The stapling member includes an anvil and a cartridge between which the tissues are sandwiched, and a cutter. Staples are applied to the anvil from the cartridge for stapling the tissues and the cutter cuts the tissue while it applies a high-frequency current thereto.

Abstract: Provided on the side of a distal end of an insertion part are an observation ultrasonic transducer for acquiring an ultrasonic image and a therapeutic ultrasonic transducer for outputting a therapeutic ultrasonic wave so as to be focused. Positioning or the like between the observation ultrasonic transducer and the therapeutic ultrasonic transducer is so conducted that a focusing point at which the therapeutic ultrasonic wave is focused is locked to a predetermined position within a scanning range of the observation ultrasonic wave. If the position of the focusing point is locked whereby a lesion part to be treated is set to a predetermined position on an ultrasonic image, it is necessarily possible to conduct the position setting to the focusing point. It is also made possible to confirm the position of the lesion part and to acoustically observe a state of the lesion part during irradiation of the therapeutic ultrasonic wave.

Abstract: Disclosed herein is a surgical device for applying surgical fasteners to body tissues in order to fasten the body tissues together. The device comprises an operation section having a housing having an inner space completely sealed from the outside, drive elements electrically driven and arranged in the inner space of the operation section, an insertion section including a housing which has a first end portion containing the fasteners and having an opening through which the fasteners are to be applied, and a second end portion removably coupled to the housing of the operation section, fastener-applying elements located in the housing of the insertion section, for applying the fasteners from the opening to body tissues, and force-transmitting elements for transmitting drive force from the drive elements to the fastener-applying elements.

Abstract: A trocar comprises an obturator having a piercing tip, and a cannula for forming a passage in tissue that is punched by the piercing tip. The cannula is formed from a flexible tube or a coil tube and transforms and libitum in accordance with the shape of the surgical tool that is to be inserted into the body cavity through the cannula. Therefore, the trocar of the invention allows insertion of a surgical tool curved in a circular arc into the body cavity without requiring no enlargement of the inside diameter of the cannula.
