Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings and examples. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and are not intended to limit the scope of the present utility model.
As shown in fig. 1 and 2, the utility model relates to a single-sided three-frequency ultrasonic endoscopic probe, which comprises an acoustic backing layer 1, a piezoelectric composite layer 2 and an acoustic matching layer 3, wherein the piezoelectric composite layer 2 is arranged on the acoustic backing layer 1, the acoustic matching layer 3 is arranged on the piezoelectric composite layer 2, the piezoelectric composite layer 2 comprises three-frequency single-frequency piezoelectric composite layers, the single-frequency piezoelectric composite layers are connected with a core wire, a ground wire 4 is arranged in the acoustic backing layer, and the core wire and the ground wire 4 are intersected at a core wire and ground wire combination point 5. The acoustic backing layer is an epoxy glue acoustic backing layer. The whole inner snoop head is made of high-frequency composite material.
The piezoelectric composite layer 2 includes a 15MHZ piezoelectric composite layer 21, a 20MHZ piezoelectric composite layer 22, and a 10MHZ piezoelectric composite layer 23, the 15MHZ piezoelectric composite layer 21 being connected to a 15MHZ core wire 24, the 20MHZ piezoelectric composite layer 22 being connected to a 20MHZ core wire 25, the 10MHZ piezoelectric composite layer 23 being connected to a 10MHZ core wire 26.
The 15MHZ core 24, the 20MHZ core 25, the 10MHZ core 26 and the ground wire 4 meet at a core-ground wire joint 5.
The top of the 15MHZ core wire 24 is provided with a 15MHZ core wire connecting point 27, the top of the 20MHZ core wire 25 is provided with a 20MHZ core wire connecting point 28, and the top of the 10MHZ core wire 26 is provided with a 10MHZ core wire connecting point 29.
When excitation voltage is given to a 15MHz core ground wire connection point, a 15MHz core wire and a ground wire input energy into a 15MHz piezoelectric composite layer, then energy (ultrasonic waves: electric energy is converted into mechanical energy) is generated from the 15MHz piezoelectric composite layer, back energy is attenuated by an acoustic backing, front energy is released to an object to be detected through an acoustic matching layer (the material can better release the energy to the external object) to realize ultrasonic detection, pulse waves reflected by a detected defect point are absorbed through the 15MHz piezoelectric composite layer, and then the detected defect point is imaged into reality through an instrument algorithm, and the probe is characterized in that: the longitudinal wave detection distance is short and the definition is high.

The utility model provides a single-sided three-frequency ultrasonic endoscopic probe, which has high detection efficiency, is greatly improved in manpower and material resources, is simple to operate, and is safe and higher in practicability. Compared with the prior ultrasonic endoscopic probe, the ultrasonic endoscopic probe has the advantages that the ultrasonic endoscopic probe belongs to a single-frequency probe before, and three kinds of frequency signals which cannot be detected simultaneously (three points of long longitudinal range, clear longitudinal near range and large transverse detection range) cannot be achieved on one side.
