Technical Field

[0001] The present invention relates to the field of medical instruments, and specifically to a breast tomosynthesis elastography device. Background Art

[0002] Breast cancer is a phenomenon in which breast epithelial cells undergo uncontrolled proliferation under the action of various carcinogenic factors. In the early stage of the disease, it often presents symptoms such as breast lumps, nipple discharge, and enlarged axillary lymph nodes. In the late stage, due to distant metastasis of cancer cells, multiple organ lesions may occur, directly threatening the life of the patient. Due to the increasing number of breast cancer patients in recent years, breast cancer has also become a malignant disease that is highly regarded among the female population. Therefore, breast examinations are even more important.

[0003] Among the existing breast examinations, the use of ultrasonic tomosynthesis elastography examination is the most effective examination method, which has irreplaceable advantages such as a low error rate, no harm to the body, and low examination costs.

[0004] Therefore, it is necessary to design a breast tomosynthesis elastography device to address the deficiencies of existing breast examination devices. Summary of the Invention

[0017] The cavity block is fixedly installed at the top of the pinion gear and is arranged inside the water tank.

[0018] The bellows spring is fixedly installed at the top of the cavity block.

[0019] The chute is opened on the upper surface of the cavity block, and the chute is opened on the left side of the bellows spring.

[0020] The slider is slidably arranged inside the chute, and the slider is fixedly connected to the right side of the bellows spring.

[0021] Preferably, the slider further includes:

[0022] The support piece is arranged on the upper surface of the slider. The support piece fits against the right edge of the slider, and the connection mode between the support piece and the slider is snap connection.

[0023] The sound transmission piece is fixedly arranged at the upper end of the support piece.

[0024] Preferably, the brake handle further includes:

[0025] The brake wire is fixedly connected to the right side of the brake handle. The brake wire passes through the pinion gear, the cavity block and the bellows spring, and is connected to the left side of the slider.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: The device for breast tomosynthesis elastography can be used to examine breast lesions, detect possible diseased tissues, so as to achieve early detection and early treatment of breast cancer. The device uses ultrasonic waves to detect the breast in depth, and at the same time uses a sound transmission piece to squeeze the breast 360 degrees, form an image in a computer, and then compare the elasticity of the body to detect the location of the lesion, so as to realize the examination of breast lesions. The device has the characteristics of low examination cost and no harm to the body, and elastography can assist tomographic imaging in the diagnosis of the affected area.

[0027] 1. Through the water tank, the device uses ultrasonic waves for detection and imaging. Since ultrasonic waves have better propagation effects in water, the water tank needs to be filled with water, which is beneficial to ultrasonic wave propagation and imaging, ensures the normal operation of the device, improves imaging clarity, and at the same time avoids water leakage. The water-proof bearing is used to ensure that there is no water leakage during normal rotation.

[0028] 2. By utilizing the extrusion effect of the extrusion mechanism, since the hardness of the tumor lesion site in the body is harder than that of normal muscle and fat tissues, during the process of extruding human tissues near the tumor outside the body, the normal softer muscle and fat will deform significantly, while the harder tumor lesion tissues hidden in the muscle and fat will deform less or not at all. Ultrasonic imaging takes an image before extruding human tissues and another image after extruding human tissues. By comparing the two images, tissues with less or no deformation can be found, and it can be determined that they are suspected lesion tissues. By pulling the brake lever, the brake wire is pulled, thereby pulling the slider, so that the acoustic transmission sheet squeezes the breast. The acoustic transmission sheet allows ultrasonic waves to pass through without affecting imaging, facilitating the detection by the annular ultrasonic probe and completing the imaging.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1-3As shown in the figure, the breast tomosynthesis elastography device includes: a water tank 1 for containing water to facilitate ultrasonic wave propagation and imaging, and an annular ultrasonic probe 2 that moves up and down is arranged inside it; an extrusion mechanism 8 that is rotatably arranged inside the water tank 1; a grip 3 that is arranged below the water tank 1; a brake lever 4 that is arranged inside the grip 3, and the connection method between the brake lever 4 and the grip 3 is a sliding connection. The grip 3 further includes: a bevel gear 6 that is fixedly connected to the right side of the grip 3; a locking button 7 that is installed at the left end of the grip 3. The water tank 1 further includes: a water-sealing bearing 10 that is fixedly arranged at the lower end of the water tank 1. Through the water tank 1, this device uses ultrasonic waves for detection and imaging. Since ultrasonic waves have a better propagation effect in water, it is necessary to fill the water tank 1 with water, which is beneficial to ultrasonic wave propagation and imaging, ensures the normal operation of the device, improves imaging clarity, and avoids water leakage. The water-sealing bearing 10 is adopted to ensure no water leakage under normal rotation conditions.

[0035] As Figures 1-3 As shown in the figure, the extrusion mechanism 8 of the breast tomosynthesis elastography device further includes: a small bevel gear 9 that is rotatably installed at the lower end of the water-sealing bearing 10, and the small bevel gear 9 extends to the inside of the water tank 1. The small bevel gear 9 is connected to the bevel gear 6 through meshing; a cavity block 15 that is fixedly installed at the top of the small bevel gear 9 and is arranged inside the water tank 1; a corrugated spring 12 that is fixedly installed at the top of the cavity block 15; a chute 11 that is opened on the upper surface of the cavity block 15, and the chute 11 is opened on the left side of the corrugated spring 12; a slider 13 that is slidably arranged inside the chute 11, and the slider 13 is fixedly connected to the right side of the corrugated spring 12. The slider 13 further includes: a support piece 14 that is arranged on the upper surface of the slider 13, the support piece 14 fits the right edge of the slider 13, and the connection method between the support piece 14 and the slider 13 is a snap connection; an acoustic transmission sheet 16 that is fixedly arranged at the upper end of the support piece 14. The brake lever 4 further includes: a brake wire 5 that is fixedly connected to the right side of the brake lever 4, and the brake wire 5 passes through the small bevel gear 9, the cavity block 15, and the corrugated spring 12 and is connected to the left side of the slider 13. By using the extrusion of the extrusion mechanism 8, since the hardness of the tumor lesion site in the body is harder than that of the normal muscle and fat tissue, during the process of squeezing the human tissue near the tumor outside the body, the normal softer muscle and fat will deform significantly, while the harder tumor lesion tissue hidden in the muscle and fat will deform less or not deform. The ultrasonic imaging takes an image before squeezing the human tissue and an image after squeezing the human tissue. By comparing the two images, the tissue with less or no deformation can be found, and it can be determined as a suspected lesion tissue. By pulling the brake lever 4 and pulling the brake wire 5, the slider 13 is pulled, so that the acoustic transmission sheet 16 squeezes the breast. The acoustic transmission sheet 16 can allow ultrasonic waves to pass through without affecting imaging, thus completing the elasticity detection.

[0036] In summary, during use, the tester needs to place the breast into the annular ultrasonic probe 2 of the water tank 1. The annular ultrasonic probe 2 starts ultrasonic detection and performs imaging processing. After imaging is completed, the breast needs to be squeezed. By rotating the grip 3, the bevel gear 6 is driven to rotate, causing the small bevel gear 9 to start rotating. While the small bevel gear 9 is rotating, the water-proof bearing 10 prevents water leakage in the water tank 1, thereby driving the extrusion mechanism 8 to start rotating. When the rotation reaches the angle to be squeezed, the locking button 7 is pressed to complete the angle locking. The brake handle 4 is pulled, and the brake handle 4 pulls the brake wire 5. The brake wire 5 passes through the small bevel gear 9 and through the cavity block 15, pulling the slider 13. The slider 13 slides in the chute 11. At the same time, the corrugated spring 12 can reset the slider 13, and the corrugated spring 12 also prevents water leakage. A support piece 14 is clamped on the slider 13, and a sound-transmitting piece 16 is connected above to achieve the extrusion of the breast. After extrusion, the annular ultrasonic probe 2 performs another detection and imaging, and the results of the two imaging are compared to find the difference in elasticity between the two, thereby realizing the positioning of the diseased tissue. The image comparison is completed by a computer. (Or during the dynamic extrusion process, the computer can identify tissues with less deformation). The computer can directly mark the suspected diseased tissues with less deformation or no deformation.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
