Embodiment Construction

[0027] The ultrasonic probe provided in this embodiment is an important part of ultrasonic diagnostic imaging equipment. The interior of the ultrasonic probe is provided with a heat-conducting film. The heat-conducting film is attached between the acoustic window and the matching layer or penetrates in the acoustic window. Graphite film, flexible graphite film has the characteristics of high thermal conductivity, so that the heat conduction film can transfer the heat energy inside the ultrasonic probe to the heat dissipation mechanism at the rear end, which improves the heat dissipation effect.

[0028] In one embodiment, an ultrasonic probe is provided, and the ultrasonic probe mainly uses a heat conduction film to accelerate heat dissipation.

[0029] Such as figure 1 As shown, the ultrasonic probe of the present embodiment mainly includes an acoustic window 2, a matching layer 3, a piezoelectric layer 4, a backing block 5 and a heat conduction film 6, and the surrounding of...

Abstract

The invention discloses an ultrasonic probe which includes an acoustic window, a matching layer, a piezoelectric layer, a backing block and a thermally conductive film. The thermally conductive film is attached between the acoustic window and the matching layer or arranged in the acoustic window in a penetrating mode, and the thermally conductive film extends out of the acoustic window in the direction of the backing block. Since the thermally conductive film is attached between the acoustic window and the matching layer or arranged in the acoustic window in a penetrating mode, and the thermally conductive film extends out of the acoustic window in the direction of the backing block, the thermally conductive film can transfer heat energy inside an ultrasonic probe body to a heat dissipation mechanism at the rear end , the heat dissipation effect is improved, and the problem that the ultrasonic probe is hot is effectively solved.

Description

technical field [0001] The present application relates to medical testing equipment, in particular to an ultrasonic probe. Background technique [0002] Ultrasound probe is an important part of ultrasonic diagnostic imaging equipment, mainly including acoustic window, matching layer, piezoelectric layer and backing block, and also includes circuit board connecting signal and ground. The working principle of the ultrasonic probe is to use the piezoelectric effect to convert the excitation electric pulse signal of the ultrasonic machine into an ultrasonic signal into the patient's body, and then convert the ultrasonic echo signal reflected by the tissue into an electrical signal, so as to realize the detection of the tissue. During the conversion process of electric-acoustic signal, the working ultrasonic probe will generate a lot of heat, which will cause the temperature of the probe to rise. On the one hand, the heating of the probe may affect the personal safety of the pat...
