Abstract
An electrode device is for microwave coagulation therapy disclosed in which the direction of its electrode tip can be controlled by operation in its proximal region. The device comprises: a handpiece provided with a rigid hollow support shaft extending toward a distal end, a movable support provided at the distal end of the support shaft and carrying thereon an electrode, a coaxial cable which is connected at its proximal end to a coaxial connector and extending through the support shaft and connected in the movable support to the electrode, wherein: (a) the movable support comprises one or more links each surrounding the coaxial cable and longitudinally connected to the distal end of the support shaft so that the movable support can be bent and stretched in a single plane, and (b) the electrode device comprises a resilient stiff member fixed at one of its end to the deflection side of the most distal one of the links composing the movable support and extending through the support shaft and so connected at its proximal end to a control section of the handpiece that the resilient stiff member can be pulled and pushed back at the proximal end of the handpiece.
