Based on the embodiments in the embodiment, other embodiments obtained by those skilled in the art without any creative work belong to the protection scope of the present invention.

Reference in the specification to "one embodiment" or "an example" means that a particular feature, structure or characteristic described in connection with the embodiment itself may be included in at least one embodiment of the patent disclosure. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

The first embodiment is as follows:

as shown in fig. 1, the present embodiment provides a tactile ultrasonic photoacoustic breast cancer detector, which is used for detecting breast cancer, the overall shape of the detector is similar to that of a female bra, and a patient needs to wear the detector on his body during detection, and the detector includes a cup portion 1, a tactile module for collecting tactile pressure signals, an ultrasonic detection module for collecting ultrasonic signals, and a photoacoustic detection module for collecting photoacoustic signals, wherein the cup portion 1 is used for providing a necessary space required by the worn breast, and also provides a space for the tactile module, the ultrasonic detection module, and the photoacoustic detection module.

The distribution of the tactile sensors 21, the ultrasonic probe 3 and the phased LED array in the cup part 1 is as shown in fig. 2, the tactile module comprises a plurality of tactile sensors 21, the plurality of tactile sensors 21 are uniformly distributed on the inner side wall of the cup part 1, the tactile sensors 21 are additionally provided with a telescopic device 22 for applying pressure to the part to be detected, and the part to be detected extends to the part to be detected through the telescopic device 22, so that the tactile sensors 21 are applied with pressure. The telescoping device 22 may be a pneumatic telescoping rod and/or an electric telescoping rod, but is not limited thereto.

The photo acoustic detection module comprises a phased LED array comprising a number of LED light sources 4 distributed over the inner side walls of the cup portion 1. A plurality of LED light sources 4 included in the phased LED array irradiate the organ to be detected from different directions, and then the ultrasonic probe 3 receives sound waves emitted by the tissues of the organ to be detected absorbing the heat of the LED light sources 4.

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 touch sensor 21 and the LED light source 4 are alternately and uniformly distributed on the inner side wall of the cup portion 1, and the distribution area of the touch sensor and the LED light source is smaller than the surface area of the inner side wall of the cup portion 1, so as to reserve the installation position of the ultrasonic probe 3, and the ultrasonic probe 3 is uniformly distributed on the inner side wall of the cup portion 1 corresponding to the root of the breast. When the patient wears the touch ultrasonic photoacoustic breast cancer detector, the touch sensor 21 and the telescopic device 22 only perform touch detection on the front half part of the breast, and the plurality of ultrasonic probes 3 surround the root part 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. The piezoelectric sensor array element layer 33 is used for transmitting/receiving ultrasonic waves to complete the sound electricity and electricity-electricity conversion work, and can convert an electric signal into an ultrasonic signal and convert the ultrasonic signal into an electric signal, namely, the piezoelectric sensor array element layer has double functions of ultrasonic transmission and ultrasonic receiving. Under the power-on state, the piezoelectric material can generate elastic deformation, so that ultrasonic waves are generated; in the opposite case, when the ultrasonic wave passes through the piezoelectric material, it can generate elastic deformation, and then the voltage is changed. The backing material layer 34 serves to dampen vibrations from the piezoelectric material, shorten the wavelength and improve axial resolution. The ultrasonic probe generates a desired image by controlling an ultrasonic signal transmitted therefrom or using a received ultrasonic signal, and allows the image to be displayed in real time, without radiation exposure, with high safety. The ultrasound probe 3 further comprises a support frame 35. The support frame 35 is used for mounting the ultrasonic probe 3 on the inner side wall of the cup portion 1, and the sequence of the layers of the ultrasonic probe 3 sequentially from the detected organ to the inner side wall of the cup portion 1 is as follows: the acoustic lens layer 31, the matching layer 32, the piezoelectric sensor array layer 33, and the backing material layer 34, in this embodiment, the backing material layer 34 of the ultrasonic probe 3 is mounted on the support frame 35, that is, the piezoelectric sensor array layer 33 is located between the matching layer 32 and the backing material layer 34. The acoustic lens layer 31, matching layer 32, and piezoelectric sensor array layer 33 are mounted on a support frame 35 by a backing material layer 34.

When the tactile ultrasonic photoacoustic breast cancer detector is used, a patient wears the tactile ultrasonic photoacoustic breast cancer detector provided by the embodiment:

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. The sequence of the ultrasonic probes 3 for transmitting ultrasonic waves and the sequence of the ultrasonic probes 3 for receiving ultrasonic waves can be flexibly set by a doctor according to actual clinical needs, and are not limited herein. Compared with the existing ultrasonic examination, generally, the ultrasonic examination is of a supination type, the handheld ultrasonic probe is clung to the breast skin for detection, the ultrasonic image mainly takes two-dimensional imaging, and the breast tissue is soft, so that the breast can deform along with the extrusion of the probe, and the conventional ultrasonic examination method cannot accurately image.

In the aspect of the photoacoustic detection module, the coupling agent is also needed to be assisted, and the coupling agent is the same as the coupling agent in the aspect of the ultrasonic detection module, and the details are not repeated here. When the photoacoustic detection is carried out, the irradiation sequence of the LED light sources 4 included in the phased LED array is preset, the LED light sources 4 included in the phased LED array irradiate the detected organ from different directions according to the preset sequence, and when the tissue of the detected organ is irradiated by light beams, the energy of the light is absorbed by the tissue to generate thermoelastic expansion, and then sound waves are generated. Because tumor cells stimulate the generation of new blood vessels during growth, the distribution of local aerobic and anoxic hemoglobin of the tumor is changed, and therefore, when the tumor cells are irradiated by near infrared light, different absorption rates which are obviously different from surrounding tissues can be generated, and further, different sound wave emission is generated. The ultrasonic probe 3 receives the sound wave generated by the tissue of the organ to be detected absorbing the heat of the LED light source 4. Three-dimensional acoustic data of the detected organ can be obtained by irradiating the tissue of the detected organ from different directions, and then image reconstruction is carried out to form an accurate three-dimensional functional image. Different from a single laser light source of the photoacoustic system in the prior art, the embodiment adopts the cheaper LED as the light source, so that the overall price of the touch ultrasonic photoacoustic breast cancer detector is low.

When the tactile ultrasonic photoacoustic breast cancer detector provided by the embodiment is used, three modalities can be imaged simultaneously or respectively, or any two modalities can be selected for imaging according to actual clinical requirements of doctors, which is not limited herein.

The touch sense ultrasonic photoacoustic breast cancer detector provided by the embodiment can perform autonomous tomography in a standing state of a patient to form an accurate three-dimensional image, the ultrasonic probe forms a photoacoustic image by means of a phased LED array while providing a three-dimensional image of an ultrasonic morphological structure, and can also provide a large amount of information such as the form, hardness, size, margin, activity, homogeneity inside a tumor body and the like of a lesion inclusion block, so that information from various imaging sources can be comprehensively expressed on one image, the diagnosis accuracy is improved, a doctor can know the comprehensive condition of lesion tissues or organs conveniently, a more accurate diagnosis is made or a more scientifically optimized treatment scheme is made, the patient does not need to carry out detection in multiple places, the burden of the patient is reduced, and the diagnosis efficiency is improved.
