Description

Technical Field

[0001] The invention relates to the technical field of breast X-ray imaging equipment, and in particular to a breast positioning photography mechanism and a breast X-ray imaging equipment. Background Art

[0002] At present, in the diagnosis and treatment process of breast diseases, X-ray imaging is often used to take X-ray photos of the patient's breast or breast sampled tissue to detect abnormal conditions such as tumors or calcified tissue. In the scenario where a breast tissue biopsy is required and a breast tissue puncture sampling is required, the punctured tissue needs to be X-rayed after sampling to confirm whether the sampling area is accurate. Existing breast X-ray imaging equipment needs to move the patient's breast to make room for X-ray imaging of the breast tissue specimen obtained by sampling, and it is impossible to complete the shooting of the specimen without moving the patient's breast. And each time the patient's breast is moved, the breast needs to be repositioned when the puncture sampling is performed again, resulting in multiple compression and trauma to the patient's breast, increasing the pain suffered by the patient during the sampling process. For this reason, it is necessary to design a new breast positioning photography mechanism that can realize X-ray imaging of the sampled specimen without moving the patient's breast. Summary of the invention

[0003] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a breast positioning photography mechanism that can achieve X-ray imaging of breast tissue sampling specimens in a specimen box module without moving the patient's breast, thereby avoiding multiple compression and trauma to the patient's breast and improving the detection experience of medical staff and patients.

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below. Figure 1 and Figure 2, an embodiment of the present invention provides a breast positioning photography mechanism, including a support arm 100, a carrier platform 200, an X-ray tube (not shown in the figure), a positioning mechanism 300, a collimator 400 and a control system. The support arm 100 is used to connect with the frame of the device, the carrier platform 200 and the X-ray tube are respectively arranged at both ends of the support arm 100, the carrier platform 200 is used to carry the patient's breast, and the X-ray tube is used to emit X-rays to the carrier platform 200. The positioning mechanism 300 is arranged on the support arm 100, and is used to fix the patient's breast in the center of the carrier platform 200. The collimator 400 is arranged on the side of the X-ray tube facing the carrier platform 200, and is used to adjust the irradiation range of the X-rays emitted by the X-ray tube on the carrier platform 200. The control system is used to control the operation of the X-ray tube, the positioning mechanism 300 and the collimator 400. At least one first mounting structure 220 for mounting the specimen box module 210 is disposed on the carrier 200, and a second mounting structure 213 matching the first mounting structure 220 is disposed on the specimen box module 210. The specimen box module 210 is detachably mounted on the carrier 200 through the first mounting structure 220 and the second mounting structure 213. A sensor for detecting the specimen box module 210 is disposed at the first mounting structure 220, and a trigger structure for triggering the sensor is disposed on the second mounting structure 213, and the sensor is electrically connected to the control system.

[0029] When the breast positioning photography mechanism needs to perform X-ray imaging on the breast tissue specimen obtained by puncture sampling, there is no need to operate the positioning mechanism 300 to release the positioning of the patient's breast. The specimen only needs to be placed in the specimen box module 210 and the specimen box module 210 is installed on the carrier 200. After the control system detects the trigger structure on the specimen box module 210 through the sensor, the control system controls the position of the light shield of the collimator 400 according to the preset parameters to adjust the irradiation range of the X-ray emitted by the X-ray tube, so that the X-ray just irradiates the range of the specimen box module 210, thereby completing the X-ray imaging of the breast tissue sample without moving the patient's breast and reducing the irradiation of the patient with X-rays. By adopting the breast positioning photography mechanism, the number of repeated positioning of the patient's breast during the detection process can be reduced, thereby avoiding multiple compression and trauma to the breast during the detection process, and there is no need for medical staff to frequently operate the equipment, thereby improving the detection experience of medical staff and patients.

[0030] It is understandable that the puncture sampling of the patient's breast tissue can be completed by the medical staff holding the puncture device, or by the medical staff operating the puncture sampling mechanism under the guidance of the X-ray image. The carrier 200 can be installed on the support arm 100 in a quick-release manner. Different carrier modules are provided with mechanisms with different functions. The function of the carrier 200 can be realized by replacing the carrier 200. The carrier 200 is provided with an electrical connection interface for electrically connecting to the control system in the support arm 100, such as a USB interface, a plug terminal or a TYPE-C interface. The control system can determine whether the carrier 200 is provided with a puncture sampling function by detecting the electrical signal of the electrical connection interface. Refer to Figures 1 to 3 On the carrier platform module with automatic puncture sampling function, a puncture mechanism 500 is arranged on the table top of the carrier platform 200, and the puncture mechanism 500 includes a puncture sampling mechanism 510 and a puncture transverse movement mechanism 520. The puncture sampling mechanism 510 is used to puncture and sample the patient's breast. The puncture sampling mechanism 510 is arranged on the puncture transverse movement mechanism 520. The puncture sampling mechanism 510 can be moved laterally relative to the carrier platform 200 under the drive of the puncture transverse movement mechanism 520, so as to avoid the puncture sampling mechanism 510 blocking the X-ray when the specimen box module 210 is subjected to X-ray imaging, thereby affecting the shooting result.

[0031] Reference Figure 3 In this embodiment, the puncture sampling mechanism 510 includes a puncture device 511, a puncture lifting mechanism 512 and a puncture longitudinal movement mechanism 513. The puncture device 511 is arranged on the puncture longitudinal movement mechanism 513, the puncture longitudinal movement mechanism 513 is arranged on the puncture lifting mechanism 512, and the puncture lifting mechanism 512 is arranged on the puncture transverse movement mechanism 520. The puncture device 511 can move longitudinally relative to the carrier 200 under the drive of the puncture longitudinal movement mechanism 513, and can cooperate with the puncture transverse movement mechanism 520 to adjust the puncture position. The puncture longitudinal movement mechanism 513 can move up and down relative to the table of the carrier 200 under the drive of the puncture lifting mechanism 512, so that the puncture cone of the puncture device 511 can penetrate into the breast tissue of the breast fixed on the carrier 200 by the positioning mechanism 300, and complete the puncture sampling of the breast tissue.

[0032] It can be understood that in some embodiments, in order to be able to more flexibly perform X-ray imaging of breast tissue samples without moving the patient's breast, so as to avoid X-rays irradiating other parts of the patient such as the arm, a pair of first mounting structures 220 are provided on the support platform 200, and the two first mounting structures 220 are respectively arranged on both sides of the positioning mechanism 300 and the puncture mechanism 500. When in use, the specimen box module 210 can be installed on the first mounting structure 220 on either side according to actual needs. The control system controls the collimator 400 to adjust the radiation range of the X-ray according to the actual installation position of the specimen box module 210, so that the X-ray irradiates the side where the specimen box module 210 is installed.

[0033] It is understandable that the sensor can be triggered by the trigger structure in a contact or non-contact manner, and the sensor can be a photoelectric switch, a Hall sensor 222 or a micro switch, etc. Figure 4 In this embodiment, the sensor is a Hall sensor 222, and the trigger structure is a magnet 214. The Hall sensor 222 is disposed on a sensor circuit board 221, and is electrically connected to the control system through the sensor circuit board 221. The sensor circuit board 221 is disposed behind the first mounting structure 220, so that after the specimen box module 210 is mounted on the table of the carrier 200, the Hall sensor 222 can detect the magnetic field of the magnet 214.

[0034] It is understandable that the first mounting structure 220 and the second mounting structure 213 can be detachably connected through a quick-release structure such as a magnetic attraction or a tenon structure, so that the specimen box module 210 can be quickly assembled and disassembled without the need for other tools. Figures 5 to 9 In this embodiment, a traverse mechanism cover 521 for protecting the puncture traverse mechanism 520 is disposed outside the puncture traverse mechanism 520. The front end surface of the traverse mechanism cover 521 is perpendicular to the table surface of the carrier 200, and serves as a mounting surface for mounting the specimen box module 210. The first mounting structure 220 is disposed on the front end surface of the traverse mechanism cover 521. The first mounting structure 220 is a U-shaped tenon, and the U-shaped opening of the first mounting structure 220 faces upward. The second mounting structure 213 is a slot that matches the shape of the tenon. The magnet 214 is disposed on one side of the slot. The sensor circuit board 221 is disposed on the inner side of the traverse mechanism cover 521. The sensor circuit board 221 is disposed directly behind the corresponding first mounting structure 220. When the first mounting structure 220 is inserted into the second mounting structure 213, the magnet 214 is aligned with the corresponding Hall sensor 222.

[0035] Reference Figure 8 and Fig. 9In this embodiment, the specimen box module 210 includes two types: a common photographic specimen box and an enlarged photographic specimen box. When the common photographic specimen box is installed on the carrier 200, the box body 212 fits the table surface of the carrier 200; when the enlarged photographic specimen box is installed on the carrier 200, there is a certain height difference between the box body 212 and the table surface of the carrier 200, so that after the X-ray irradiates the specimen in the box body 212, the image projected to the detector under the carrier 200 becomes larger, thereby realizing the shooting of the enlarged X-ray image of the specimen. In order to facilitate the control system to distinguish between the two specimen box modules 210, refer to Figure 4 A Hall sensor 222 is disposed at each end of the sensor circuit board 221. The relative position relationship between the magnet 214 and the second mounting structure 213 on the ordinary photographic specimen box and the magnified photographic specimen box is different. Figure 8 and Fig. 9 In this embodiment, the magnet 214 of the common photography specimen box is arranged on the right side of the second mounting structure 213, and the magnet 214 of the magnified photography specimen box is arranged on the left side of the second mounting structure 213. When the Hall sensor 222 on the right side of the sensor circuit board 221 is triggered, it is determined that the common photography specimen box is installed, and the control system controls the collimator 400 and the X-ray tube and other mechanisms according to the preset parameters of the common specimen photography; when the Hall sensor 222 on the left side of the sensor circuit board 221 is triggered, it is determined that the magnified photography specimen box is installed, and the control system controls the collimator 400 and the X-ray tube and other mechanisms according to the preset parameters of the magnified specimen photography.

[0036] It is understandable that the box body 212 of the specimen box module 210 is preferably flat, and a detachable box cover 211 is provided on the box body 212 to place the breast tissue specimen. The box body 212 is preferably made of transparent or translucent material, waterproof and visible, and the specimen photography surface, that is, the bottom surface of the box body 212, should not have artifacts. Fig. 9 The bottom surface of the box body 212 of the magnifying photographic specimen box is provided with a bracket with a conical side surface, and the second mounting structure 213 is provided on the back side of the bottom of the bracket.

[0037] Reference Figure 1 and Figure 2 In this embodiment, the positioning mechanism 300 includes a compression plate 310 and a compression plate driving mechanism 320. The compression plate 310 is disposed between the carrier 200 and the collimator 400. The compression plate 310 is connected to the compression plate driving mechanism 320. The compression plate 310 can approach or move away from the table surface of the carrier 200 under the drive of the compression plate driving mechanism 320. The compression plate 310 is provided with an avoidance hole for the puncture cone of the puncture device 511 to pass through. It is understandable that the positioning mechanism 300 can also adopt other commonly used fixing structures in clinical practice to complete the fixation of the patient's breast.

[0038] It is understandable that the puncture lifting mechanism 512, the puncture longitudinal movement mechanism 513, the puncture transverse movement mechanism 520 and the compression plate driving mechanism 320 can be a linear driving mechanism composed of components such as a motor, a lead screw pair and a slide rail, and the collimator 400 is composed of a field lamp for displaying the irradiation range, four light shielding plates for adjusting the irradiation range and their respective light shielding plate driving mechanisms, multiple filters, and a filter switching driving mechanism for driving the switching of the filters. The specific structure of the above mechanism is common knowledge in the art, and the specific structure of the above mechanism is not repeated here.

[0039] Reference Fig.10 The control system includes a photography control unit, a collimator 400 control unit and a positioning control unit, and the photography control unit, the collimator 400 control unit and the positioning control unit are connected to each other in communication. The photography control unit is used to determine the parameters of the X-ray tube according to the installation of the specimen box module 210, and drive the X-ray tube to emit X-rays of corresponding power to the carrier 200. The collimator 400 control unit is used to adjust the irradiation range of the X-ray according to the installation of the specimen box module 210, and the positioning control unit is used to control the positioning mechanism 300 to work. It can be understood that the collimator 400 control unit includes a collimator 400 control processor, a field lamp driving circuit, a driving circuit of a light shielding plate driving mechanism of four light shielding plates in front, behind, left and right, and a driving circuit of a filter switching driving mechanism. The photography control unit includes a photography control processor and an X-ray tube driving circuit. The positioning mechanism 300 includes a positioning control processor and a driving circuit of a compression plate driving mechanism 320. The processors are connected to each other through a CAN bus for communication, and each driving circuit is electrically connected to the corresponding processor.

[0040] Reference Fig.11 In some embodiments, the control system also includes a puncture sampling control unit for controlling the puncture mechanism 500, and the puncture sampling control unit includes a puncture sampling control processor and a driving circuit for the puncture transverse movement mechanism 520, the puncture lifting mechanism 512 and the puncture longitudinal movement mechanism 513.

[0041] In the breast positioning photography mechanism of the embodiment of the present invention, the control system first detects whether the puncture mechanism 500 is installed. If the puncture mechanism 500 is detected, it is determined that the puncture photography mode needs to be adopted. The control system controls the collimator 400 to cover the puncture sampling area with the irradiation range of the X-ray, and controls the X-ray tube to expose the puncture sampling area with the exposure parameters required for the puncture photography. Then, it is detected whether there is a specimen box module 210 installed on the carrier 200. After the specimen box module 210 is detected, it is determined that the specimen photography mode needs to be adopted. Then, the installation position and type of the specimen box module 210 are determined according to the position of the triggered Hall sensor 222, and the collimator 400 is controlled to adjust the irradiation range of the X-ray according to the installation position and type of the specimen box module 210, so that the range of the X-ray covers the box body 212 of the specimen box module 210. At the same time, the puncture transverse movement mechanism 520 is controlled to drive the puncture sampling mechanism 510 to translate a certain distance in the opposite direction of the specimen box module 210 to avoid blocking interference to the X-ray, and the X-ray tube is controlled to expose the breast tissue specimen in the specimen box module 210 according to the exposure parameters required for specimen photography. After the exposure is completed, the X-ray image is sent to the image processing unit, the specimen area is automatically identified, and the image is automatically cropped and segmented to obtain the X-ray image of the breast tissue specimen area. If the installation of the puncture mechanism 500 and the specimen box module 210 is not detected, it is determined that the ordinary photography mode needs to be adopted, and the control system controls the collimator 400 to cover the range of the compression plate 310 with the irradiation range of the X-ray, and controls the X-ray tube according to the exposure parameters of the ordinary photography mode to expose the breast of the patient who is compressed and positioned on the carrier 200.

[0042] The breast X-ray imaging device of the embodiment of the present invention includes the above-mentioned breast positioning photography mechanism, and the support arm 100 of the breast positioning photography mechanism is rotatably arranged on the frame of the device so as to perform X-ray photography detection on the patient's breast more flexibly.
