[0038] The pointer 3 is arranged in the center of the test plate 2, the pointer 3 is perpendicular to the test plate 2, and the two ends of the pointer 3 respectively extend from the test plate 2.

[0039] It should be further pointed out that when calibrating the lateral positioning precision, the test plate 2 is arranged horizontally on the horizontal mounting part, the pointer is arranged in the center of the test plate 2, and then the calibration seat 1 is placed on the treatment head, the needle tip is found in the B-ultrasound image, and the lateral deviation value of the needle tip center to the focal point central axis is measured.

If the size of the damage point meets the expectation, it is proved that the output power of the treatment head is accurate.

[0054] Exemplarily, the pointer 3 is made of metal, which has high density and elastic modulus, and the reflection of ultrasonic waves is very obvious.

[0055] Exemplarily, the calibration seat 1 is made of plastic.

[0056] It also needs to be explained that the calibration seat 1 is made of plastic material, which can reduce the weight of the calibration seat 1 while ensuring the structural strength.

[0059] Exemplarily, the calibration seat 1 is further provided with a connecting groove on the large-end end face, and the connecting groove is used to connect with the treatment head.
