Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments. The present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1 and 2, the present embodiment provides an ultrasonic probe device for a magnetic wave blade, including a probe holder 1, a probe connecting rod 2, and a plurality of probe units 3. The main body of the probe bracket 1 is cylindrical, and a plurality of mounting grooves 11 are distributed on the circumferential side wall of the bracket. The number of the mounting grooves 11 corresponds to the number of the probe units 3, and is at least two, and preferably three in the present embodiment. The number of the probe units 3 is three, and the three probe units are respectively embedded into the three mounting grooves 11. A focusing surface 31 is provided on the outer side surface of each probe unit 3 for forming an ultrasonic focusing focus, and the focusing surface 31 is wound around the probe holder 1. Generally, the ultrasound focusing focal points of at least one probe unit 3 and other probe units 3 are different in depth, and in the present embodiment, it is preferable that the curvature radii of the three focusing planes 31 are different from each other, so that the depth distances of the corresponding ultrasound focusing points are different from each other, and thus, the method can be applied to three different application scenarios. One end of the probe connecting rod 2 is fixedly connected with the probe bracket 1 through threads, and the external probe control mechanism can drive the probe bracket 1 to rotate and move through the probe connecting rod 2. The whole manufacturing material of the probe device is nonmagnetic and is completely compatible with MRI equipment.
