Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of molybdenum target diagnostic equipment, and specifically provides a device and method for early screening and diagnosis of breast surgical tumors. Background Technique
[0002] For early diagnosis of breast tumors, molybdenum target examination is generally used. Molybdenum target examination generates images by using low-dose X-rays to penetrate breast tissues to detect abnormalities. Molybdenum target examination can detect microcalcifications and early tumors. During molybdenum target examination, medical staff assist the patient to place the breast on the examination platform and gently press and fix it with a transparent plate. After the transparent pressing plate presses down, the shape of the breast is uniform in thickness. Then, X-rays are used to take pictures of the breast. The high-resolution imaging of X-rays enables even tiny calcification points (less than 1 mm) to be detected. Compressing the breast during the examination can reduce the overlap of breast tissues and make calcification foci easier to detect. Compression makes the breast tissues evenly distributed and reduces the possibility of missed diagnosis.
[0003] When using existing molybdenum target examination equipment to examine patients, a transparent pressing plate needs to be used to directly press down on the patient's breast. For patients with relatively dense breast tissues, the pain caused by the extrusion of the pressing plate is relatively obvious. Moreover, existing molybdenum target examination equipment can only diagnose the breast tissues under the pressing plate, and the breast tissues distributed around the breast cannot be pressed by the pressing plate, so the accuracy of the diagnosis result is reduced. Therefore, it does not meet the existing requirements. For this reason, we propose a device and method for early screening and diagnosis of breast surgical tumors. Summary of the Invention
[0004] The present invention provides a device and method for early screening and diagnosis of breast surgical tumors, which have the beneficial effects that before the pressing plate presses down on the patient's breast, rollers are used to roll and stretch the breast. After rolling, the shape of the breast is relatively uniform, increasing the contact area between the breast and the pressing plate, thereby reducing the pain caused by the pressing plate. After the breast is stretched, the breast tissues located around the breast will move downward to the area under the pressing plate, enabling the pressing plate to press more breast tissues, thus improving the accuracy of the diagnosis result. This solves the problems mentioned in the above background technique that when using existing molybdenum target examination equipment to examine patients, a transparent pressing plate needs to be used to directly press down on the patient's breast. For patients with relatively dense breast tissues, the pain caused by the extrusion of the pressing plate is relatively obvious. Moreover, existing molybdenum target examination equipment can only diagnose the breast tissues under the pressing plate, and the breast tissues distributed around the breast cannot be pressed by the pressing plate, so the accuracy of the diagnosis result is reduced.

[0018] A nozzle is arranged on the molybdenum target machine body, an oil pipe is mounted at the bottom of the oil storage box, and the other end of the oil pipe is connected to the nozzle.
[0019] This solution also proposes a method for early breast cancer screening and diagnosis, including the following specific steps:
[0020] S1. Preparation before examination: Clean and disinfect the support plate, rollers and pressing plate. The patient faces the molybdenum target machine, and the medical staff assists the patient to place the breast on the support plate. The patient leans forward so that the arc plate contacts the body, and the displacement of the electric slider is set according to the shape and size of the patient's breast;
[0021] S2. Flatten the breast: The pressing plate flattens the patient's breast to make the breast tissue evenly distributed and reduce breast stacking. The specific process is as follows:
[0022] a1. Make the rollers roll and stretch the breast;
[0023] a2. Before the rollers separate from the breast, the pressing plate gradually changes from an inclined state to a horizontal state;
[0024] a3. Spray lubricating oil at the bottom of the pressing plate. When the pressing plate presses down on the breast, it moves back and forth.
[0025] S3. Shooting and post-processing: Turn on the X-ray machine to shoot the breast. After shooting, the pressing plate resets. Finally, clean the lubricating oil on the support plate, roller and pressing plate.
[0026] The present invention has the following beneficial effects:
[0027] 1. For the early screening and diagnosis device and method for breast surgery tumors, when the pressing plate moves downward with the electric slider, the cross bar arranged on the pressing plate drives the trapezoidal plate to move downward. Since the hypotenuse of the trapezoidal plate is in sliding contact with the guide rod, when the trapezoidal plate moves downward, the guide rod drives the roller to move along the through groove. At the same time, the roller rolls the breast. After rolling, the shape of the breast changes from a hemispherical shape to a disc shape, thus increasing the contact area between the breast and the pressing plate, which is beneficial to reducing the pain caused to the patient by the direct downward pressure of the pressing plate. In addition, when the roller rolls, the friction between the roller and the breast skin tissue pulls the breast to move. Further, the breast skin tissue pulls the breast tissue around the breast to move, so that more breast tissues are pulled to the bottom of the pressing plate, increasing the number of breast tissues under the pressing plate. Therefore, the molybdenum target device can capture more breast tissues each time, reducing the occurrence of missed detections, and thus improving the accuracy of the diagnosis result.
[0028] 2. For the early screening and diagnosis device and method for breast surgery tumors, during the downward movement of the pressing plate, the arc plate is always in contact with the upper edge of the breast. Therefore, when the roller stretches the breast, the breast tissue around the breast moves under the pressing plate, and the friction between the arc plate and the skin tissue will prevent the breast tissue from resetting. In addition, before the roller detaches from the breast, under the action of the torsion spring, the pressing plate gradually tends to be horizontal from an inclined state. Before the breast shape rebounds, the pressing plate flips and presses down, ensuring the effectiveness of the roller stretching, ensuring that there is a large contact area between the breast and the pressing plate, and thus increasing the reliability of the device.
[0029] 3. For the early screening and diagnosis device and method for breast surgery tumors, the movable rod is slidably installed on the electric slider. When the electric slider drives the movable rod to move downward, the second convex block installed at one end of the movable rod is in sliding contact with the first convex block. With the cooperation of the third compression spring, the movable rod moves back and forth while moving downward. The movable rod further drives the pressing plate to move back and forth through the mounting plate, sleeve, positioning rod and cross bar. The pressing plate moves back and forth while pressing down on the breast, which is beneficial to kneading the breast tissue in the middle of the breast evenly and preventing the breast tissue from piling up. Since the breast tissue is evenly distributed under the pressing plate, after X-ray imaging, it is beneficial to improve the clarity of the shooting and facilitate the observation of the early calcification spots of breast cancer, thus further improving the reliability of the device;
[0030] In addition, when the trapezoidal plate moves downward, the bottom end of the trapezoidal plate contacts the airbag, and the gas in the airbag enters the oil storage box through the trachea. The pressure in the oil storage box increases, causing the lubricating oil in the oil storage box to be sprayed to the bottom of the pressing plate through the oil pipe and the nozzle, thereby reducing the friction between the pressing plate and the patient's breast, reducing the discomfort caused by the pressing plate pressing down on the breast and rubbing it back and forth, and improving the practicality of the device.

DETAILED DESCRIPTION
[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0043] Embodiment 1: This embodiment aims to solve the problem that when the existing molybdenum target examination equipment examines the patient, it is necessary to use a transparent pressing plate to directly press down the patient's breast. For patients with dense breast tissue, the pain caused by the pressing plate is more obvious. In addition, the existing molybdenum target examination equipment can only diagnose the breast tissue under the pressing plate, while the breast distributed around the breast cannot be pressed by the pressing plate, so the accuracy of the diagnosis result is reduced. Please refer to Figures 1 to 10 A breast surgical tumor early screening and diagnosis device comprises a molybdenum target machine body 101, a support plate 102 for placing a breast is installed on the molybdenum target machine body 101, an electric slider 104 is arranged on the molybdenum target machine body 101, and a pressing plate 103 for pressing the breast is arranged on the side of the electric slider 104, wherein a pair of vertical plates 201 are installed on the support plate 102, and a through groove 204 is opened on the vertical plate 201, and the through groove 204 is arranged as an arc through groove, and the bottom of the pressing plate 103 is provided with The roller 202 has guide rods 212 installed at both ends of the roller 202. The guide rods 212 are slidably installed in the through grooves 204. The guide rods 212 are transmission-connected with the pressing plate 103. When the pressing plate 103 moves downward, the roller 202 rolls and stretches the breast. When the pressing plate 103 moves upward, the roller 202 automatically resets. After the breast is rolled, the shape of the breast changes from a hemispherical shape to a disc shape. After the breast is stretched, the breast tissue around the breast is pulled to the lower side of the pressing plate 103.
[0044] Specifically, please refer to Figure 1 and Figure 2 A cross bar 203 is provided on the pressing plate 103. Trapezoidal plates 205 are installed at both ends of the cross bar 203. The hypotenuse of the trapezoidal plate 205 is in sliding contact with the guide rod 212. In addition, a rotating block 213 is rotatably installed on the guide rod 212. A first vertical plate 208 is installed on the vertical plate 201. A return spring 207 is connected between the first vertical plate 208 and the rotating block 213. Specifically, when the trapezoidal plate 205 moves downward, the guide rod 212 moves from the top to the bottom along the through slot 204. At the same time, the roller 202 rolls on the breast. When the roller 202 rolls, the friction between the roller 202 and the breast skin tissue pulls the breast to move. Further, the breast skin tissue pulls the mammary gland tissue around the breast, so that more mammary glands are pulled to the bottom of the pressing plate 103.
[0045] In addition, a pair of second vertical plates 206 are provided on the vertical plate 201. A first compression spring 209 is installed on the side of the second vertical plate 206 close to the through slot 204. The other end of the first compression spring 209 is installed with a rack 210. The side of the rack 210 is in sliding fit with the vertical plate 201. A gear 214 for meshing with the rack 210 is provided on the guide rod 212. With the cooperation of the first compression spring 209, the rack 210 and the gear 214 are always meshed. Therefore, when the gear 214 moves, it will drive the guide rod 212 and the roller 202 to rotate. Moreover, when the roller 202 rotates, a friction force will be generated between the roller 202 and the breast skin tissue, and the direction of this friction force is the same as the direction in which the skin tissue is pulled.
[0046] This embodiment also proposes a method for early screening and diagnosis of breast surgical tumors, including the following specific steps:
[0047] S1. Preparation before examination: Clean and disinfect the support plate 102, the roller 202 and the pressing plate 103. The patient faces the mammography machine, and the medical staff assists the patient to place the breast on the support plate 102. The patient leans forward so that the arc plate 304 contacts the body. According to the shape and size of the patient's breast, the displacement of the electric slider 104 is set;
[0048] S2. Flattening the breast: The pressing plate 103 flattens the patient's breast to make the mammary gland distribution uniform and reduce the mammary gland stacking. The specific process is as follows:
[0049] a1. Make the roller 202 roll and stretch the breast;
[0050] a2. Before the roller 202 separates from the breast, the pressing plate 103 gradually changes from an inclined state to a horizontal state;
[0051] a3. Spray lubricating oil on the bottom of the pressing plate 103. When the pressing plate 103 presses the mammary gland, it moves back and forth;
[0052] S3. Shooting and post-processing: Turn on the X-ray machine to take pictures of the breast. After shooting, the pressing plate 103 resets, and finally, clean the lubricating oil on the support plate 102, the roller 202, and the pressing plate 103.
[0053] In this embodiment: When the pressing plate 103 moves downward with the electric slider 104, the cross bar 203 arranged on the pressing plate 103 drives the trapezoidal plate 205 to move downward. Since the hypotenuse of the trapezoidal plate 205 is in sliding contact with the guide rod 212, when the trapezoidal plate 205 moves downward, the guide rod 212 drives the roller 202 to move along the through groove 204. At the same time, the roller 202 rolls the breast. After rolling, the shape of the breast changes from a hemispherical shape to a disc shape, thereby increasing the contact area between the breast and the pressing plate 103, which is beneficial to reducing the pain caused to the patient by the direct downward pressure of the pressing plate 103. In addition, when the roller 202 rolls, the frictional force between the roller 202 and the breast skin tissue pulls the breast to move. Further, the breast skin tissue pulls the breast tissue around the breast to move, so that more mammary glands are pulled to the bottom of the pressing plate 103, increasing the number of mammary glands under the pressing plate 103. Therefore, the molybdenum target device can capture more mammary gland tissues each time, reducing the occurrence of missed detections, and thus improving the accuracy of the diagnosis results.
[0054] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that after the breast is rolled and stretched by the roller, the shape of the breast will rebound to a certain extent, reducing the rolling and stretching effects. This embodiment is an improvement based on Embodiment 1. Specifically, please refer to Figures 1 to 10 , an arc-shaped plate 304 is installed at one end of the pressing plate 103 close to the patient. The arc-shaped plate 304 abuts against the upper skin tissue of the patient's breast. The pressing plate 103 is hinged to the cross bar 203. A torsion spring 215 is arranged on the cross bar 203. One end of the torsion spring 215 is connected to the cross bar 203, and the other end of the torsion spring 215 is connected to the pressing plate 103. The pressing plate 103 is inclined. When the electric slider 104 moves to the set position, the pressing plate 103 returns to horizontal.
[0055] It should be noted that when the electric slider 104 moves downward, the arc-shaped plate 304 always contacts the upper edge of the breast. Therefore, when the roller 202 stretches the breast, the breast tissue around the breast moves under the pressing plate 103, and the frictional force between the arc-shaped plate 304 and the skin tissue will hinder the reset of the breast tissue. In addition, since the roller 202 will separate from the breast after rolling and stretching the breast, before the roller 202 separates from the breast, the pressing plate 103 gradually returns to horizontal under the action of the torsion spring 215. Before the shape of the breast rebounds, the pressing plate 103 turns from an inclined state to a horizontal state for downward pressing.
[0056] Specifically, please refer to Figure 1 、 Figure 5 、 Figure 6, a movable rod 301 is arranged on the side of the electric slider 104. Mounting plates 302 are installed at both ends of the movable rod 301. A sleeve 303 is installed at one end of the mounting plate 302 away from the movable rod 301. A positioning rod 306 is slidably installed in the sleeve 303. The bottom end of the positioning rod 306 is fixedly connected to the cross bar 203. A second compression spring 307 is arranged in the sleeve 303. The other end of the second compression spring 307 abuts against the positioning rod 306. A connecting rod 305 is hinged to the bottom of the mounting plate 302. The other end of the connecting rod 305 is hinged to the pressing plate 103. Moreover, the length of the connecting rod 305 is less than the total length of the sleeve 303 and the positioning rod 306.
[0057] It should be noted that in the initial state, although the torsion spring 215 is in a state of storing energy, due to the length of the connecting rod 305 being less than the total length of the sleeve 303 and the positioning rod 306, the pressing plate 103 cannot rotate with the cross bar 203 as the axis. As the electric slider 104 moves downward, since the arc-shaped plate 304 contacts the edge of the patient's breast, the positioning rod 306 moves into the sleeve 303 against the elastic force of the second compression spring 307. At this time, the total length of the sleeve 303 and the positioning rod 306 gradually decreases, and the pressing plate 103 can rotate smoothly. Under the action of the torsion spring 215, the pressing plate 103 gradually rotates and tends to be horizontal.
[0058] In this embodiment: during the downward movement of the pressing plate 103, the arc-shaped plate 304 always contacts the upper edge of the breast. Therefore, when the roller 202 stretches the breast, the mammary gland tissue around the breast moves to the lower part of the pressing plate 103. The frictional force between the arc-shaped plate 304 and the skin tissue will hinder the reset of the mammary gland tissue. In addition, before the roller 202 detaches from the breast, under the action of the torsion spring 215, the pressing plate 103 gradually changes from an inclined state to a horizontal state. Before the breast shape rebounds, the pressing plate 103 flips and presses downward, ensuring the effectiveness of the stretching by the roller 202, ensuring that there is a large contact area between the breast and the pressing plate 103, thereby increasing the reliability of this device.
[0059] Embodiment 3, this embodiment aims to promote the solution to the problem that more mammary gland tissues are distributed in the middle of the breast. After the breast is squeezed by the pressing plate, the mammary gland tissues are piled up together. After X-ray imaging, the imaging of the mammary gland tissues is not clear. This embodiment is an improvement based on Embodiment 2. Specifically, please refer to Figures 1 to 10 , the movable rod 301 is slidably installed on the electric slider 104. A reciprocating mechanism 4100 is arranged on the molybdenum target machine body 101. When the pressing plate 103 presses down on the breast, the pressing plate 103 moves reciprocally.
[0060] Specifically, please refer to Figure 8The reciprocating mechanism 4100 includes a No. 3 vertical plate 401, which is mounted on the molybdenum target machine body 101. A plurality of No. 1 protrusions 402 are arranged on the No. 3 vertical plate 401. A No. 2 protrusion 403 is arranged at one end of the movable rod 301 close to the No. 1 protrusion 402. The No. 2 protrusion 403 is located directly above the No. 1 protrusion 402, and the No. 2 protrusion 403 and the No. 1 protrusion 402 are both arranged to be protrusions with semicircular cross-sections. A No. 3 compression spring 404 is arranged at the other end of the movable rod 301. An L-shaped plate 411 is installed on the electric slider 104, and the other end of the No. 3 compression spring 404 is in conflict with the L-shaped plate 411.
[0061] Also, please refer to Figure 10 , an airbag 405 is provided on the support plate 102, and the airbag 405 is located directly below the trapezoidal plate 205. An oil storage box 407 for storing lubricating oil is provided on the support plate 102, and an air pipe 406 is connected between the oil storage box 407 and the airbag 405. A one-way valve 408 for balancing the air pressure is installed on the top of the oil storage box 407. The one-way valve 408 can only allow gas to enter the oil storage box 407 in one direction. A nozzle 410 is provided on the molybdenum target machine body 101, and an oil pipe 409 is installed at the bottom of the oil storage box 407. The other end of the oil pipe 409 is connected to the nozzle 410, wherein the airbag 405 is configured as a rubber airbag, and the airbag 405 can automatically restore by spring cooperation. The one-way valve 408 includes a baffle hinged in the pipeline, and the baffle can only be opened in one direction by spring cooperation, thereby ensuring the one-way passage of gas. The specific structure and principle of the one-way valve 408 are well known to those skilled in the art and will not be described here.
[0062] In this embodiment: the movable rod 301 is slidably mounted on the electric slider 104. When the electric slider 104 drives the movable rod 301 to move downward, the second protrusion 403 installed at one end of the movable rod 301 slides and contacts with the first protrusion 402. With the cooperation of the third compression spring 404, the movable rod 301 reciprocates while moving downward. The movable rod 301 further drives the pressing plate 103 to reciprocate through the mounting plate 302, the sleeve 303, the positioning rod 306 and the cross bar 203. The pressing plate 103 reciprocates while pressing the breast downward, which is conducive to kneading the breast tissue in the middle of the breast evenly and preventing the breast tissue from piling up. Since the breast tissue is evenly distributed under the pressing plate 103, after X-ray imaging, it is conducive to improving the clarity of the shooting and facilitating the observation of the calcification foci of early breast cancer, thereby further improving the reliability of the device.
[0063] In addition, when the trapezoidal plate 205 moves downward, the bottom end of the trapezoidal plate 205 abuts against the airbag 405, and the gas in the airbag 405 enters the oil storage box 407 through the air pipe 406. The pressure in the oil storage box 407 increases, causing the lubricating oil in the oil storage box 407 to be sprayed onto the bottom of the pressing plate 103 through the oil pipe 409 and the nozzle 410. Therefore, the friction between the pressing plate 103 and the patient's breast is reduced, the discomfort caused by the pressing plate 103 pressing down on the breast and rubbing back and forth is reduced, and the practicability of the device is improved.
