Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.
[0020] As shown in FIGS. 1 and 2 , this example includes a B ultrahigh frequency linear array probe 2 with a wire 3 . A fixing frame 1 is fixed at the bottom of the B ultrahigh frequency linear array probe 2 , and the bottom surface of the fixing frame 1 is on the same plane as the bottom surface of the B ultrahigh frequency linear array probe 2 . An oblique puncture frame 5 is fixed on one side of the fixed frame 1 , and the overall direction axis 15 of the puncture frame 5 forms an included angle of 30° with the bottom surface of the B ultrahigh frequency linear array probe 2 . The setting of the puncture frame 5 requires ensuring that the overall direction axis 15 of the puncture frame 5 intersects with the vertical line downward from the center point of the B ultrahigh frequency line array probe 2 (this line is perpendicular to the bottom surf...
