|20140135756||ENDOSCOPIC FORCEPS - An endoscopic forceps is provided. A movable blade electrode and a fixed blade electrode form a pair of electrodes. The fixed blade electrode is electrically contacted onto an external electric conductor of a coaxial cable in the sheath conduit. A force application point of the movable blade electrode is connected to a center electric conductor of the coaxial cable. A pivot point of the movable blade electrode is provided on the movable blade electrode. The coaxial cable is slid with respect to the sheath conduit so that parallel moving added to the coaxial cable is transmitted to the movable blade electrode as turnable moving about the pivot point via the force application point of the movable blade electrode. A high frequency wave can be applied between the movable blade electrode and the fixed blade electrode via the external electric conductor and the center electric conductor of the coaxial cable.||05-15-2014|
|20140128860||BIPOLAR NEEDLE TYPE MICROWAVE OPERATION DEVICE - The present invention provides a bipolar needle type microwave operation device, wherein at least one pair of rod-like electrodes are parallel to a center axis of the electrodes in their entirety, an insulator being filled between the paired electrodes. Preferably, at least two pairs of electrodes are alternate so that the electrodes having the same polarity are not adjacent to each other, and the ends of the paired electrodes having the same polarity are bridged with the same material as the electrodes. Preferably, a perpendicular distance between each of the electrodes and the center axis is within 2 mm.||05-08-2014|
