Abstract

An electronic radial ultrasonic probe comprising an electronic radial array which comprises a plurality of ultrasonic transducers being continuously arrayed circularly around an insertion axis as center and also for which a transmission/reception of an ultrasonic wave is controlled by electronically selecting the plurality of ultrasonic transducer, comprises: a support member equipped on the electronic radial array; a lock member featured with a cavity in which the support member is inserted and with a lock groove for locking a balloon which is mounted in a manner to cover the electronic radial array and in which an ultrasonic medium is filled; and a filler member which is constituted by an adhesive material converting from a fluid state to a solid state, and is filled in the cavity.

Claims1

Dependent claims

An electronic radial ultrasonic probe comprising:

ultrasonic transducer elements composed of a first electrode and a second electrode facing each other, wherein the ultrasonic transducer elements are continuously lined up and form a cylinder so that the first electrode is positioned on an inner circumference side;
a tubular member positioned within the cylinder so as to be parallel to an axial direction of the cylinder;
a circular flange connected to one end of the tubular member, wherein the circular flange is positioned within the cylinder so as to be vertical to the axial direction of the cylinder, and wherein an opening of the tubular member and an opening of the torus are in communication with each other;
an electrode pad equipped on the flange and electrically connected to the first electrode;
and
a signal wire introduced through an other end of the tubular member, leading from the opening of the flange, and connected to the electrode pad.
