Full visual angle micro-convex B-ultrasound probe

The utility model relates to a type-B ultrasonic probe, in particular to a whole visual angle and micro convex array type-B ultrasonic probe used in gynecological operations, which is mainly used for the type-B ultrasonic monitoring in gynecological operations. The type-B ultrasonic probe includes a hollow plastic shell, a signal transmission line which is positioned in the plastic shell and a transducer which is fixed at the front end of the plastic shell and is connected with the signal transmission line; the type-B ultrasonic probe is characterized in that the plastic shell is shaped like L, the surface of the plastic shell which is contacted with a lower vane of a standard speculum takes the shape of an inwardly concave arc surface, and the radian of the arc surface is identical to that of the surface of the lower vane of the standard speculum. The beneficial effects of the type-B ultrasonic probe are that: (1) the whole visual angle and micro convex array type-B ultrasonic probe of the utility model can
