The ultrasonic probe comprises ultrasonic probes 3, which ultrasonic probes 3 are also distributed on the inner side walls of the cup portion 1. In this embodiment, the ultrasonic detection module further comprises a couplant bag 6 and a couplant conduit 5 which are located outside the cup portion 1, and the couplant in the couplant bag 6 enters the cup portion 1 through the couplant conduit 5.
In this embodiment, the tactile sensors 21 and L ED light sources 4 are alternately and uniformly distributed on the inner side wall of the cup portion 1, the distribution area of the tactile sensors 21 and L ED light sources is smaller than the surface area of the inner side wall of the cup portion 1 to reserve the installation position of the ultrasonic probe 3, the ultrasonic probes 3 are uniformly distributed on the inner side wall of the cup portion 1 corresponding to the root of the breast, after the tactile ultrasonic photoacoustic breast cancer detector is worn by a patient, the tactile sensors 21 and the telescopic device 22 only perform tactile detection on the front half part of the breast, and the ultrasonic probes 3 surround the root of the breast to perform ultrasonic detection and photoacoustic detection on the vicinity of the breast.
As shown in fig. 3, the ultrasonic probe 3 includes an acoustic lens layer 31, a matching layer 32, a piezoelectric sensor array layer 33, and a backing material layer 34. The acoustic lens layer 31 is an end directly contacting the organ to be detected to focus in the lateral and/or longitudinal directions. The matching layer 32 serves to reduce multiple reflections due to the difference in acoustic impedance between the skin and the acoustic lens layer 31. The piezoelectric sensor array element layer 33 includes a piezoelectric material, which may be a piezoelectric crystal or a composite piezoelectric material, and the geometric shape and size thereof may be designed according to the diagnostic scenario and requirements, including various shape designs such as a convex array, a linear array, etc., which are not limited herein.

in the tactile module, since the tactile sensor 21 is disposed in the cup portion 1, the doctor cannot apply pressure to the tactile sensor 21 by hand, and therefore the extension/contraction device 22 attached to the tactile sensor 21 extends to apply pressure to the organ tissue 36 to be detected. By using the tissue elastography principle, the physical pressure signal of clinical palpation is converted into a digital signal, an image of surface pressure distribution can be immediately generated, and two-dimensional and three-dimensional images of lesions can be displayed in real time. When the tactile sensor 21 touches the mammary gland and a certain pressure is applied by the extension device 22, the tactile sensor 21, i.e. the pressure sensor, can obtain the reaction forces generated by the tissues with different hardness, and then the information of the forces is detected by the tactile sensor 21 and converted into an electric signal through an electric circuit. The image features formed by the generated digital signals of the touch module are clear and definite, a great deal of information such as the shape, hardness, size, margin, activity, tumor internal homogeneity and the like of a lesion mass can be obtained, the recognition and analysis are easy, and the real-time recording and playback can be carried out.
In the aspect of the ultrasonic detection module, as the ultrasonic detection needs the assistance of the couplant, the couplant in the couplant bag 6 enters the cup part 1 through the couplant conduit 5, and as the tactile ultrasonic photoacoustic breast cancer detector is worn, the couplant entering the cup part 1 can be naturally extruded in a narrow space and smeared on the surface of the detected organ. And the couplant in the couplant bag 6 can enter the cup part 1 in a manual extrusion mode, a conveying device can be additionally arranged on the couplant bag 6, the couplant is automatically injected according to the set demand of the couplant, and the couplant in the cup part 1 can be recovered to the couplant bag 6 through the conveying device after use. The transfer of fluids, such as coupling agents, is not limited herein, as is known in the art. When ultrasonic detection is carried out, ultrasonic wave transmitting sequences of a plurality of ultrasonic probes 3 and ultrasonic wave receiving sequences of the plurality of ultrasonic probes 3 are preset, according to the preset, the ultrasonic probes 3 which transmit ultrasonic waves, the ultrasonic probes 3 which receive the ultrasonic waves receive transmitted ultrasonic waves 37 and/or reflected ultrasonic waves 38, the organ tissues 36 to be detected are subjected to tomography, the mammary gland is detected in an all-around mode, accurate three-dimensional images are formed, and judgment of a doctor on the position of the breast tumor is improved.
