できる。The ultrasonic standoff 31 is inserted between the ultrasonic probe and the surface of the subject, and the material of the body surface contact portion is a thin film of rubber, a high molecular compound, a water bag made of resin, or a gel-like substance. It is composed of an ultrasonic transmission material. The puncture needle has an oblique through hole 31a for guiding the puncture needle into the subject projected by the ultrasonic beam, and the periphery 31b of the through hole exit is convex. The skin is stretched by the compression by the convex portion, and the elasticity of the skin in the living body insertion portion when the puncture needle 32 is inserted is reduced, and the adhesion between the ultrasonic standoff 31 and the body surface is increased. As a result, the generation of an air layer between the ultrasonic standoff 31 and the body surface can be suppressed, and an ultrasonic image without shadow can be obtained.
