The detection mechanism comprises an X-ray detector and an ultrasonic detector, and when the to-be-detected object is subjected to X-ray detection, the ultrasonic detector can move out of the detection surface of the X-ray detector in the second direction, so that the ultrasonic detector cannot block the X-ray detector from receiving X-rays, and the X-ray detection can be completed. And when the to-be-detected object is subjected to ultrasonic detection, the ultrasonic detector can move to a proper position along the second direction to emit ultrasonic waves to perform ultrasonic detection on the to-be-detected object. In the process, X-ray image acquisition and ultrasonic image acquisition do not interfere with each other and do not influence each other, lesion details such as tiny calcification can be recognized through X-ray images, a complete image structure of lesion tissues can be seen through ultrasonic images, and the use flexibility of the detection mechanism is improved. Moreover, the time for completing X-ray examination and ultrasonic examination of the patient is greatly shortened, and the examination efficiency is improved.

Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a detection mechanism, a medical imaging device, and a medical puncture system. Background Art

[0002] At present, the examination of breast diseases and the early screening of breast cancer are mainly completed through breast X-ray imaging or breast ultrasound imaging. The principle of breast X-ray imaging is the same as that of other X-ray devices in terms of the exposure principle. It mainly utilizes the penetration performance of X-rays and the difference in the response of different human tissues to X-rays during the process of X-rays penetrating the human body. Finally, different energy accumulations form breast images with different gray levels (including two-dimensional and three-dimensional tomographic imaging) on the image. The principle of breast ultrasound imaging is to use an ultrasonic beam to scan the human body and obtain an image of internal organs by receiving and processing the reflected signals.

[0003] Taking X-ray imaging as an example, although X-ray imaging can identify lesion details such as microcalcifications and can detect potential breast lesions earlier, it is difficult to see the complete image structure of the lesion tissue. Therefore, the existing detection mechanisms have the problem of low usage flexibility. Summary of the Utility Model

[0004] Based on this, in view of the problem of low usage flexibility existing in the existing medical imaging systems, it is necessary to provide a detection mechanism.

[0005] A detection mechanism, the detection mechanism includes:

[0006] A compression unit for compressing an object to be detected;

[0007] An X-ray detector located on one side of the compression unit along a first direction to obtain an X-ray image of the object to be detected;

[0008] An ultrasonic detector spaced from the X-ray detector and capable of moving relative to the X-ray detector along a second direction.

[0009] In one embodiment, the X-ray detector is capable of moving relative to the compression unit along the first direction.

[0010] In one embodiment, the detection mechanism further includes an ultrasonic coupling medium, and at least a part of the ultrasonic coupling medium is disposed between the ultrasonic detector and the object to be detected.

[0011] In one embodiment, the ultrasonic coupling medium includes a liquid couplant;

[0012] The detection mechanism further includes a container, the liquid couplant is disposed in the container; the ultrasonic detector is located in the container.

[0013] In one embodiment, the X-ray detector is located inside the container.

[0014] In one embodiment, the ultrasonic coupling medium includes a first solid ultrasonic coupling material disposed between the ultrasonic detector and the object to be detected.

[0015] In one embodiment, the ultrasonic coupling medium includes a second solid ultrasonic coupling material disposed between the ultrasonic detector and the first solid ultrasonic coupling material.

[0016] In one embodiment, the detection mechanism includes a seal, and both the first solid ultrasonic coupling material and the ultrasonic detector are disposed within the accommodation space of the seal; the ultrasonic detector can reciprocate within the seal along the second direction.

[0017] In one embodiment, the detection mechanism further includes a bearing mesh disposed between the ultrasonic detector and the object to be detected.

[0018] A medical imaging device includes a frame and the above-described detection mechanism, and the detection mechanism is disposed on the frame.

[0019] In one embodiment, the frame includes a base and a support frame connected to one side of the base, and the detection mechanism is disposed on the support frame.

[0020] In one embodiment, a sliding portion extending in a first direction is provided on the support frame, and the pressing unit is slidably connected to the sliding portion.

[0021] A medical puncture system includes a puncture mechanism and the above medical imaging device.

[0022] The above detection mechanism can both collect X-ray images and ultrasonic images. When performing X-ray detection on the object to be detected, the ultrasonic detector can be moved along the second direction to outside the detection surface of the X-ray detector, so that the ultrasonic detector does not block the X-ray detector from receiving X-rays, that is, the ultrasonic detector does not affect the operation of the X-ray detector, thus enabling X-ray examination to be completed. When performing ultrasonic detection on the object to be detected, the ultrasonic detector can be moved along the second direction to a suitable position to emit ultrasonic waves for ultrasonic examination of the object to be detected. During this process, X-ray image acquisition and ultrasonic image acquisition do not interfere with each other and do not affect each other. It can not only identify lesion details such as microcalcifications through X-ray images, but also see the complete image structure of the lesion tissue through ultrasonic images, improving the flexibility of use of the detection mechanism; and the time for the patient to complete X-ray examination and ultrasonic examination is significantly shortened, improving the examination efficiency.

Detailed Description of the Embodiments

[0032] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the specific embodiments of the present application in detail with reference to the drawings. Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0033] In the description of the present application, it should be understood that if there are terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. These are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0034] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0035] In the present application, unless otherwise clearly specified and limited, if there are terms such as "mounted", "connected", "joined", "fixed", etc., these terms should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0036] In the present application, unless otherwise clearly specified and limited, if there is a description such as a first feature being "on" or "under" a second feature, the meaning may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0038] Referring to Figure 1 As shown, a detection mechanism 100 provided in an embodiment of the present application includes a pressing unit 130, an X-ray detector 110, and an ultrasonic detector 120; the pressing unit 130 is used to press (squeeze) and / or fix the object to be detected 200; the X-ray detector 110 is located on one side of the pressing unit 130 along the first direction X to obtain an X-ray image of the object to be detected 200; the ultrasonic detector 120 is spaced from the X-ray detector and can move relative to the X-ray detector 110 along the second direction Y. In an actual application scenario, the first direction is the vertical direction and the second direction is the horizontal direction. As Figure 1 shown, the first direction is indicated by the X direction and the second direction is indicated by the Y direction.

[0039] The above detection mechanism 100 can both collect X-ray images and collect ultrasonic images. When performing X-ray detection on the object to be detected 200, the ultrasonic detector 120 can be moved along the second direction Y to outside the detection surface of the X-ray detector 110, so that the ultrasonic detector 120 does not block the X-ray detector 110 from receiving X-rays, that is, the ultrasonic detector 120 does not affect the operation of the X-ray detector 110, thereby enabling X-ray examination to be completed. When performing ultrasonic detection on the object to be detected 200, the ultrasonic detector 120 can be moved along the second direction Y to a suitable position to emit ultrasonic waves to perform ultrasonic examination on the object to be detected 200. During this process, the X-ray image acquisition and the ultrasonic image acquisition do not interfere with each other and do not affect each other. It can not only identify lesion details such as microcalcifications through X-ray images, but also see the complete image structure of the lesion tissue through ultrasonic images, improving the flexibility of use of the detection mechanism 100; and the time for the patient to complete X-ray examination and ultrasonic examination is greatly shortened, improving the examination efficiency.

[0040] In some embodiments, the X-ray detector 110 may be a device that converts X-ray energy into an electrical signal for recording. The X-ray detector 110 may receive X-ray irradiation and then generate an electrical signal proportional to the radiation intensity. The strength of the signal received by the X-ray detector 110 may depend on the density of the tissue within the cross-section of the object 200 to be detected. For example, bones have a relatively high density and absorb more X-rays, so the signal received by the X-ray detector 110 is relatively weak; tissues with a lower density, such as fat, absorb fewer X-rays, and the signal obtained by the X-ray detector 110 is relatively strong. Therefore, the state of the human tissue can be determined based on the strength of the signal received by the X-ray detector 110. The X-ray detector 110 may be a flat panel detector. The detection surface of the X-ray detector 110 may be the area within the plane of the flat panel detector where the detection function can be realized. Structurally, the detection surface may be the area of the flat panel detector where the electronic components with photoelectric conversion function are located, excluding the frame.

[0041] In some embodiments, the ultrasonic detector 120 may scan the human body with an ultrasonic beam and obtain an image of internal organs by receiving and processing the reflected signals. It can be understood that when performing an ultrasonic examination, the air between the ultrasonic probe of the ultrasonic detector 120 and the patient's skin will prevent the ultrasonic waves from entering the human body. Referring to Figure 1 As shown, in some embodiments, the detection mechanism 100 further includes an ultrasonic coupling medium 140. At least a part of the ultrasonic coupling medium 140 is disposed between the ultrasonic detector 120 and the object 200 to be detected, so that the ultrasonic detector 120 can obtain the ultrasonic image of the object 200 to be detected and the ultrasonic coupling medium 140 to obtain a high-quality ultrasonic image. By using the ultrasonic coupling medium 140 to connect the ultrasonic probe and the patient's body surface, the effect of ultrasonic detection can be improved. Part of the ultrasonic coupling medium 140 may be a coupling agent with relatively low fluidity, such as a water-based coupling agent, a gel coupling agent, or an oil-based coupling agent, etc.

[0042] In some embodiments, a driving mechanism (not shown in the figure) is connected to the ultrasonic detector 120. The driving mechanism drives the ultrasonic detector 120 to move along the second direction Y, so as to avoid the X-ray detector 110 or move to a suitable detection position. The driving mechanism may be a robotic arm or a linear driving member, etc., to realize the position adjustment of the ultrasonic detector 120.

[0043] Referring to Figure 2As shown, in one embodiment, the X-ray detector 110 can move relative to the pressing unit 130 along the first direction X to adjust the distance between the X-ray detector 110 and the object to be detected 200. By moving the X-ray detector 110 closer to the object to be detected 200, the attenuation of X-rays can be reduced, and the quality of the X-ray image can be improved. Correspondingly, a driving mechanism is also connected to the X-ray detector 110, and the driving mechanism is used to drive the X-ray detector 110 to move along the first direction X.

[0044] Refer to Figure 1 or Figure 2 As shown, in one embodiment, the ultrasonic coupling medium 140 includes a liquid couplant 141; the detection mechanism 100 further includes a container 150, and both the liquid couplant 141 and the ultrasonic detector 120 are disposed in the container 150.

[0045] Among them, the container 150 forms a receiving space for accommodating the liquid couplant 141. By filling the liquid couplant 141 in the entire container 150, the isolation effect of the liquid couplant 141 from air can be ensured, thereby ensuring the quality of the ultrasonic image. The shape of the container 150 is not limited. For example, in this embodiment, the cross-sectional shape of the container 150 is rectangular. The container 150 can be made of alloy materials or polyester materials, etc. The liquid couplant 141 can be mineral oil, etc.

[0046] Refer to Figure 2 As shown, in another embodiment, both the ultrasonic detector 120 and the X-ray detector 110 are located in the container 150, and the X-ray detector 110 can move along the first direction X to reduce the attenuation of X-rays and improve the quality of the X-ray image. Among them, both the ultrasonic detector 120 and the X-ray detector 110 can be connected to the inner wall of the container 150, and the position adjustment is achieved by the movement of the ultrasonic detector 120 and the X-ray detector 110 relative to the container 150. The form of connection between the ultrasonic detector 120 and the X-ray detector 110 and the inner wall of the container 150 can be not limited, as long as the functions of relative fixation and movement can be achieved. The driving mechanism for driving the X-ray detector 110 and the ultrasonic detector 120 to move can be disposed in the container 150.

[0047] Such as Figure 2As shown, in one embodiment, the detection surface of the X-ray detector 110 is disposed opposite to the inner side surface of the container 150, wherein the inner side surface of the container 150 is the plate surface at the top of the container 150. The ultrasonic detector 120 is movably disposed in the container 150. The ultrasonic detector 120 can also move and fit against the inner side surface in the container 150. That is, X-rays can enter the detection surface of the X-ray detector 110 through the inner side surface of the container 150. The ultrasonic detector 120 moves within the container 150 as needed. The ultrasonic detector 120 can fit against the inner side surface of the container 150. When the object to be detected 200 is placed on the outer wall of the container 150, the ultrasonic detector 120 can detect the object to be detected 200 through the inner side surface of the container 150. Wherein, the object to be detected 200 can be breast tissue.

[0048] As Figure 2 shown, in some embodiments, the inner side surface of the container 150 and the X-ray detector 110 can be spaced apart, that is, there is a space between the inner side surface of the container 150 and the X-ray detector 110. The vertical distance between the inner side surface of the container 150 and the X-ray detector 110 can be adjusted as needed. The ultrasonic detector 120 can move in the horizontal plane between the inner side surface of the container 150 and the X-ray detector 110. When X-ray detection of the object to be detected 200 is required, the ultrasonic detector 120 can be moved in the horizontal plane between the inner side surface of the container 150 and the X-ray detector 110 so that the ultrasonic detector 120 is away from the object to be detected 200 and the X-ray detector 110. That is, the ultrasonic detector 120 does not block the X-ray detector 110 from receiving X-rays. At this time, the ultrasonic detector 120 does not affect the operation of the X-ray detector 110. When ultrasonic detection of the object to be detected 200 is required, the ultrasonic detector 120 can be moved between the X-ray detector 110 and the inner side surface of the container 150. Since the X-ray detector 110 does not need to operate at this time, the ultrasonic detector 120 can be moved above the X-ray detector 110 and can emit ultrasonic waves to detect the object to be detected 200.

[0049] As Figure 2As shown, in one embodiment, the detection surface of the ultrasonic detector 120 may be parallel to the inner side surface of the container 150. The path of the horizontal movement of the ultrasonic detector 120 between the X-ray detector 110 and the inner side surface of the container 150 is not limited, as long as the ultrasonic detector 120 and the X-ray detector 110 do not interfere with each other when they are working respectively. A slideway (not shown in the figure) may be provided on the plane between the X-ray detector 110 and the inner side surface of the container 150, and the ultrasonic detector 120 may slide on the slideway.

[0050] As Figure 2 As shown, in some embodiments, the X-ray detector 110 is movably arranged in the accommodation space in the vertical direction. That is, when the inner side surface of the container 150 is horizontally arranged, the X-ray detector 110 can approach or move away from the inner side surface of the container 150 in the vertical direction. When performing X-ray detection on the object to be detected 200, the X-ray detector 110 can be moved in the vertical direction to make the X-ray detector 110 approach the inner side surface of the container 150. The X-ray detector 110 approaching the inner side surface of the container 150 can improve the accuracy of X-ray reception. When the X-ray detector 110 is not required to work, the X-ray detector 110 can be moved away from the inner side surface of the container 150. A relatively large space can be left between the inner side surface of the container 150 and the X-ray detector 110. At this time, the ultrasonic detector 120 can be moved horizontally to the space between the X-ray detector 110 and the inner side surface of the container 150. Thus, the object to be detected 200 placed on the inner side surface of the container 150 can be detected by the ultrasonic detector 120. It can be understood that a slide rail arranged in the vertical direction (not shown in the figure) may be provided in the accommodation space, and the X-ray detector 110 may be slidably arranged on the slide rail. A plurality of clamping structures may be arranged at intervals on the slide rail. The clamping structures can limit the position of the X-ray detector 110 on the slide rail, that is, can define the distance of the X-ray detector 110 relative to the inner side surface of the container 150.

[0051] In one embodiment, the detection mechanism further includes a first slide rail (not shown in the figure) arranged in the horizontal direction, the first slide rail is arranged between the inner side surface of the container and the X-ray detector, and the ultrasonic detector is slidably arranged on the first slide rail. It can be understood that the ultrasonic detector can be connected to a driving mechanism, and the ultrasonic detector can be driven to move through the driving mechanism.

[0052] In one embodiment, the detection mechanism further includes a second slide rail (not shown in the figure), the second slide rail is disposed in the accommodation space along the vertical direction, and the X-ray detector is slidably disposed on the second slide rail. The X-ray detector can slide up and down along the second slide rail to adjust the distance between the X-ray detector and the object to be detected in the vertical direction, thereby improving the accuracy of X-ray reception.

[0053] As Figure 2 shown, in one embodiment, the ultrasonic detector 120 is in contact with the inner side surface of the container 150. Therefore, the ultrasonic detector 120 is closer to the object to be detected 200, and the detection effect is better. At the same time, since the ultrasonic detector 120 is in contact with the inner side surface of the container 150, the inner side surface of the container 150 defines the horizontal plane of movement of the ultrasonic detector 120, so it is convenient to guide and control the movement of the ultrasonic detector 120. At the same time, the compactness of the detection mechanism 100 can be further improved to reduce the space occupied by the detection mechanism 100.

[0054] Referring to Figure 3 shown, in one of the embodiments, the above-mentioned container 150 may not be provided. The ultrasonic coupling medium 140 includes a first solid ultrasonic coupling material 142 disposed between the ultrasonic detector 120 and the object to be detected 200. By using the first solid ultrasonic coupling material 142 to connect the ultrasonic probe to the patient's body surface, the effect of ultrasonic detection can be improved, and high-quality ultrasonic images can be obtained. The first solid ultrasonic coupling material 142 is used to support the object to be detected that is being compressed, and it can be made of a rigid material with a certain rigidity. For example, the first solid ultrasonic coupling material 142 can be a high-crystalline transparent plastic material, such as polymethylpentene (TPX), which can optimize the propagation of ultrasonic waves, improve the image quality and diagnostic accuracy.

[0055] Referring to Figure 3As shown, in one of the embodiments, the ultrasonic coupling medium 140 includes a second solid ultrasonic coupling material 143 disposed between the ultrasonic detector 120 and the first solid ultrasonic coupling material 142. Among them, the second solid ultrasonic coupling material 143 is made of a flexible material, and the second solid ultrasonic coupling material 143 can adhere to the surface of the first solid ultrasonic coupling material 142 to reduce the possibility that the rigid first solid ultrasonic coupling material 142 is not easily infiltrated and affects the coupling effect between the ultrasonic coupling medium 140 and the ultrasonic detector 120. In this way, through the cooperation of the first solid ultrasonic coupling material 142 and the second solid ultrasonic coupling material 143, the quality of the ultrasonic image is further improved. The second solid ultrasonic coupling material 143 can be an acoustic pad, which can act as an acoustic coupling medium between the ultrasonic probe and the patient's skin, help eliminate the air gap between the ultrasonic probe and the skin, ensure that ultrasonic waves can effectively be transmitted from the ultrasonic probe to the patient's body, reduce the attenuation of ultrasonic waves at the air interface, and thus improve the image quality. The acoustic pad helps increase the near-field distance of the ultrasonic probe, enables the lesion tissue to be located within the sound beam focusing area, and improves the detection ability of the lesion tissue.

[0056] Refer to Figure 4 and Figure 5As shown, in one embodiment, the detection mechanism 100 includes a seal 160 filled with a liquid couplant 141, and the first solid ultrasonic coupling material 142 and the ultrasonic detector 120 are both disposed in the accommodation space of the seal 160; the ultrasonic detector 120 can reciprocate in the seal 160 along the second direction. It can be understood that the seal 160 can be a sealed synchronous belt structure. When the ultrasonic detector 120 moves along the second direction, the seal 160 will move synchronously. And in the accommodation space of the seal 160, a liquid couplant 141 such as a water-based couplant, a gel couplant or an oil-based couplant is also provided around the first solid ultrasonic coupling material 142 and the ultrasonic detector 120, so as to discharge the air between the first solid ultrasonic coupling material 142 and the ultrasonic detector 120 and improve the coupling effect between the two. Among them, the ultrasonic detector 120 can move synchronously with the seal 160. Specifically, the ultrasonic detector 120 can be connected to an external linear drive such as a linear motor or a telescopic cylinder, and the ultrasonic detector 120 is driven by the external drive to drive the seal 160 to move synchronously; or the seal 160 can be connected to an external linear drive, and the seal 160 is driven by the external drive to drive the ultrasonic detector 120 to move synchronously, so that the ultrasonic detector 120 moves along the second direction to outside the detection surface of the X-ray detector 110 and does not affect the operation of the X-ray detector 110; or the ultrasonic detector 120 can move to a suitable position along the second direction to emit ultrasonic waves to perform ultrasonic examination on the object to be detected 200. The specific driving method can be set according to actual needs. By using a solid ultrasonic coupling material for ultrasonic coupling, the attenuation of X-rays can be reduced and the quality of X-ray images can be improved. At the same time, the layout of the entire detection mechanism 100 is more compact.

[0057] Referring to Figure 5 As shown, in one embodiment, the detection mechanism 100 further includes a carrier net 170 disposed between the ultrasonic detector 120 and the object to be detected 200. The carrier net 170 is coated with a part of ultrasonic coupling medium 140, such as a hydrogel is coated on the carrier net 170. Taking the object to be detected as a breast as an example, during breast imaging, since the breast needs to be compressed before imaging, the ultrasonic coupling medium 140 will make the breast surface slippery and the compression and positioning become difficult. Therefore, adding the carrier net 170 can not only ensure the air isolation effect, but also increase the friction between the object to be detected 200 and the ultrasonic detector 120, which is convenient for positioning. Among them, the carrier net 170 can specifically be a mesh.

[0058] As Figure 8As shown in the figure, further, an embodiment of the present application further provides a medical imaging device 10, which includes an imaging component and the detection mechanism 100 as described above. It can be understood that it also includes an X-ray emission source 500, such as an X-ray tube. An object to be detected 200 can be placed between the X-ray emission source 500 and the X-ray detector 110. The X-rays emitted by the X-ray emission source 500 can be received by the X-ray detector after passing through the object to be detected 200, and the imaging component can be used to display X-ray images and ultrasonic images in cooperation. When the medical imaging device 10 is in use, it can collect X-ray images and ultrasonic images, and the two do not interfere with each other, thus improving the flexibility of use of the medical imaging device; and the time for patients to complete X-ray examinations and ultrasonic examinations is greatly shortened, improving the examination efficiency. The imaging component can be a display screen, and the operator can observe the detection image through the display screen. In an actual application scenario, the medical imaging device can be a mammography machine.

[0059] As Figure 8 shown, in one embodiment, the medical imaging device 10 includes a frame 400, and the detection mechanism 100 is disposed on the frame 400. The frame 400 is used to support the detection mechanism 100, so that the detection mechanism 100 can remain stable even during movement, avoiding image blurring and helping to obtain high-quality detection images.

[0060] Specifically, as Figure 8 shown, the frame 400 includes a base 410 and a support frame 420 connected to one side of the base 410. The support frame 420 extends relative to the base 410, and the detection mechanism 100 is disposed on the support frame 420. Among them, the X-ray emission source 500 is disposed at the upper end of the support frame 420, and the detection mechanism 100 is disposed at the lower end of the support frame 420. The X-rays emitted by the X-ray emission source 500 can be received by the X-ray detector in the detection mechanism 100 after passing through the object to be detected.

[0061] As Figure 8 shown, further, a sliding portion 421 extending in the vertical direction is provided on the support frame 420, and the pressing unit 130 is slidably connected to the sliding portion 421. By moving the pressing unit 130 up and down along the sliding portion 421, the position of the pressing unit 130 is adjusted, so as to squeeze the object to be detected, so that the tissue to be detected of the object to be detected can be evenly compressed, reducing the tissue thickness, improving the image quality, and reducing the radiation dose. The sliding portion 421 can specifically be a chute or a guide rail and other components that can allow the pressing unit 130 to extend into.

[0062] In some other embodiments, shielding materials can also be provided inside the frame to reduce the influence of scattered X-rays on the surrounding environment and protect the health of the operator and the object to be detected.

[0063] Refer to Figure 6 and Figure 7 As shown, an embodiment of the present application further provides a medical puncture system, including a puncture mechanism and a medical imaging device as described above. In a specific embodiment, the medical puncture system can be a breast puncture system. Among them, the puncture mechanism can include a needle holding instrument for holding the puncture needle 300. Among them, the puncture direction of the puncture needle 300 can be selected according to actual needs. For example, in Figure 6 the embodiment shown, the puncture needle 300 enters the needle along the vertical direction; in Figure 7 the embodiment shown, the puncture needle 300 enters the needle along the horizontal direction.

[0064] For the above-mentioned medical puncture system, by combining an ultrasonic detector and an X-ray detector, the X detector can locate the lesion position, that is, the three-dimensional coordinates of the lesion tissue, so as to determine the puncture depth of the puncture needle. Using the needle holding instrument to hold the puncture needle can directly reach the lesion tissue; at the same time, the entire puncture process can also be observed through the ultrasonic image, so that the position of the puncture needle and the position of the lesion tissue can be observed in real time. There is no need for the doctor to repeatedly move the ultrasonic detector to judge the puncture tissue and the position of the puncture needle, so as to accurately complete the intracavitary puncture operation and improve the detection accuracy and detection efficiency. Specifically, based on the matching of the X-ray detector and the ultrasonic detector in spatial position, the matching of the acquired image coordinates can be realized through an algorithm. When observing the X-ray image, the system can automatically track the ultrasonic image, and the lesion point displayed on the X-ray image can be automatically tracked and displayed on the ultrasonic image to improve the puncture accuracy.

[0065] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0066] The above-mentioned embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
