Description

Technical Field

[0001] The present invention relates to the technical field of molybdenum target diagnostic equipment, and in particular to an early screening and diagnostic device and method for breast surgical tumors. Background Art

[0002] Early diagnosis of breast tumors generally uses mammography. Mammography uses low-dose X-rays to penetrate breast tissue to generate images to detect abnormalities. Mammography can detect tiny calcifications and early tumors. During the mammography, medical staff assist the patient in placing the breast on the examination platform and gently press it with a transparent plate to fix it. After the transparent pressing plate is pressed down, the breast shape becomes uniform in thickness. Then X-rays are used to photograph the breast. The high-resolution imaging of X-rays can detect tiny calcifications (less than 1 mm). Compressing the breast during the examination can reduce the overlap of breast tissue, making calcifications easier to detect. Compression makes the breast tissue evenly distributed, reducing the possibility of missed diagnosis.

[0003] When the existing molybdenum target examination equipment examines the patient, it is necessary to use a transparent pressure plate to directly press down the patient's breast. For patients with relatively dense breast tissue, the pain caused by the squeezing of the pressure plate is more obvious. In addition, the existing molybdenum target examination equipment can only diagnose the breast tissue under the pressure plate, while the breast distributed around the breast cannot be pressed by the pressure plate, thereby reducing the accuracy of the diagnosis result. Therefore, it does not meet the existing needs. In this regard, we propose an early screening and diagnosis device and method for breast surgical tumors. Summary of the invention

[0004] The present invention provides an early screening and diagnosis device and method for breast surgical tumors. The device and method are provided with a roller for rolling and stretching the breast before a pressure plate is pressed down on the patient's breast. The shape of the breast after rolling is relatively uniform, and the contact area between the breast and the pressure plate is increased, thereby reducing the pain caused by the pressure plate. After the breast is stretched, the mammary glands around the breast will move under the pressure plate, so that the pressure plate can press more mammary gland tissues, thereby improving the accuracy of the diagnosis result. The device and method solve the problem that the existing mammary gland target examination equipment mentioned in the above background technology needs to use a transparent pressure plate to directly press down the patient's breast when examining the patient. For patients with relatively dense breast tissues, the pain caused by the squeezing of the pressure plate is relatively obvious. In addition, the existing mammary gland target examination equipment can only diagnose the breast tissue under the pressure plate, while the mammary glands distributed around the breast cannot be pressed by the pressure plate, thereby reducing the accuracy of the diagnosis result.

[0019] This protocol also proposes a method for early screening and diagnosis of breast surgical tumors, including the following specific steps:

[0020] S1. Preparation before examination: clean and disinfect the support plate, rollers and pressure plate. The patient faces the molybdenum target machine. The medical staff assists the patient to place the breast on the support plate. The patient leans forward so that the curved plate contacts the body. The displacement of the electric slider is set according to the shape and size of the patient's breast.

[0021] S2, breast flattening: The pressing plate flattens the patient's breasts to make the breasts evenly distributed and reduce breast stacking. The specific process is as follows:

[0022] a1. Use rollers to roll and stretch the breasts;

[0023] a2. Before the roller separates from the breast, the pressing plate gradually changes from tilted to horizontal;

[0024] a3. Spray lubricating oil on the bottom of the pressing plate, and the pressing plate will move back and forth while pressing the breast;

[0025] S3, shooting and post-processing: Turn on the X-ray device to shoot the breast. After shooting, the pressing plate is reset, and finally the lubricating oil on the support plate, roller and pressing plate is cleaned.

[0026] The present invention has the following beneficial effects:

[0027] 1. The early screening and diagnosis device and method for breast surgical 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 groove, and the roller rolls the breast at the same time. The shape of the breast after rolling changes from a hemispherical shape to a disc shape, thereby 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 involves the breast to move, and further the breast skin tissue involves the breast tissue around the breast to move, so that more breasts are involved to the bottom of the pressing plate, and the number of breasts under the pressing plate is increased. Therefore, the molybdenum target device can capture more breast tissues each time, reducing the occurrence of missed detection, thereby improving the accuracy of the diagnosis result.

[0028] 2. In the device and method for early screening and diagnosis of breast surgical tumors, the arc plate is always in contact with the upper edge of the breast during the downward movement of the pressure plate. Therefore, when the roller stretches the breast, the breast tissue around the breast moves to the bottom of the pressure plate, and the friction between the arc plate and the skin tissue will hinder the repositioning of the breast tissue. In addition, before the roller is separated from the breast, the pressure plate gradually tends from tilt to horizontal under the action of the torsion spring, and before the breast shape rebounds, the pressure plate flips and presses down, ensuring the effectiveness of the roller stretching and ensuring a larger contact area between the breast and the pressure plate, thereby increasing the reliability of the device.

[0029] 3. The early screening and diagnosis device and method for breast surgical tumors, the movable rod is slidably installed on the electric slider, when the electric slider drives the movable rod to move downward, the second protrusion installed at one end of the movable rod slides and contacts with the first protrusion, and with the cooperation of the third compression spring, the movable rod reciprocates while moving downward, and the movable rod further drives the pressure plate to reciprocate through the mounting plate, sleeve, positioning rod and cross bar, and the pressure plate 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 pressure plate, after X-ray imaging, it is conducive to improving the clarity of shooting, facilitating the observation of early calcification foci of breast cancer, thereby 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] For details, please refer to Figure 1 , Figure 2 A cross bar 203 is provided on the pressing plate 103, and 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, and a No. 1 vertical plate 208 is installed on the vertical plate 201. A return spring 207 is connected between the No. 1 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 groove 204, and the roller 202 rolls the breast. When the roller 202 rolls, the friction between the roller 202 and the breast skin tissue involves the breast to move, and further the breast skin tissue involves the mammary gland tissue around the breast, so that more mammary glands are involved to the bottom of the pressing plate 103.

[0045] In addition, a pair of No. 2 vertical plates 206 are provided on the vertical plate 201, and a No. 1 compression spring 209 is installed on the side of the No. 2 vertical plate 206 close to the through groove 204, and a rack 210 is installed on the other end of the No. 1 compression spring 209. The side of the rack 210 is slidably fitted with the vertical plate 201, and a gear 214 for meshing with the rack 210 is provided on the guide rod 212. With the cooperation of the No. 1 compression spring 209, the rack 210 and the gear 214 are always meshed, so when the gear 214 moves, it will drive the guide rod 212 and the roller 202 to rotate, and the rotation of the roller 202 will generate friction between the breast skin tissue, and the direction of the friction is the same as the direction in which the skin tissue is pulled.

[0046] This embodiment also provides 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, roller 202 and pressing plate 103. The patient faces the molybdenum target machine. 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. The displacement of the electric slider 104 is set according to the shape and size of the patient's breast.

[0048] S2, breast flattening: The pressing plate 103 flattens the patient's breast to make the breast glands evenly distributed and reduce breast gland stacking. The specific process is as follows:

[0049] a1. Using the roller 202 to roll and stretch the breast;

[0050] a2. Before the roller 202 separates from the breast, the pressing plate 103 gradually changes from being inclined to being horizontal;

[0051] a3. Spray lubricating oil on the bottom of the pressing plate 103, and the pressing plate 103 moves back and forth while pressing the breast;

[0052] S3, photographing and post-processing: Turn on the X-ray device to photograph the breast. After photographing, the pressing plate 103 is reset, and finally the lubricating oil on the supporting plate 102, the roller 202 and the pressing plate 103 is cleaned.

[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, and 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 by the direct downward pressure of the pressing plate 103 to the patient. In addition, when the roller 202 rolls, the friction between the roller 202 and the breast skin tissue involves the breast to move, and further the breast skin tissue involves the mammary gland tissue around the breast to move, so that more mammary glands are involved to the bottom of the pressing plate 103, and the number of mammary glands under the pressing plate 103 is increased. Therefore, the molybdenum target device can capture more mammary gland tissue each time, reducing the occurrence of missed detection, thereby improving the accuracy of the diagnosis result.

[0054] Embodiment 2: This embodiment aims to solve the problem that after the breast is rolled and stretched by the roller, the breast shape will rebound to a certain extent, reducing the rolling and stretching effect. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figures 1 to 10 An arc plate 304 is installed at one end of the pressing plate 103 close to the patient, and the arc plate 304 contacts the skin tissue on the upper part of the patient's breast. The pressing plate 103 is hinged to the cross bar 203, and 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 tilted. When the electric slider 104 moves to the set position, the pressing plate 103 returns to the horizontal position.

[0055] It should be noted that when the electric slider 104 moves downward, the arc plate 304 is always in contact with the upper edge of the breast. Therefore, when the roller 202 stretches the breast, the breast tissue around the breast moves to the bottom of the pressing plate 103. The friction between the arc plate 304 and the skin tissue will hinder the repositioning of the breast tissue. In addition, after the roller 202 rolls and stretches the breast, the roller 202 will separate from the breast. Therefore, before the roller 202 separates from the breast, the pressing plate 103 gradually recovers to a horizontal position from being tilted under the action of the torsion spring 215. Before the breast shape rebounds, the pressing plate 103 flips from being tilted to being horizontal and presses down.

[0056] For details, please refer to Figure 1 , Figure 5 , Figure 6A movable rod 301 is arranged on the side of the electric slider 104, and 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, and 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, and a No. 2 compression spring 307 is arranged in the sleeve 303. The other end of the No. 2 compression spring 307 is in conflict with the positioning rod 306. A connecting rod 305 is hinged at the bottom of the mounting plate 302, and the other end of the connecting rod 305 is hinged to the pressure plate 103, and 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 force, since the length of the connecting rod 305 is 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, the arc plate 304 contacts the edge of the patient's breast, and the positioning rod 306 overcomes the elastic force of the No. 2 compression spring 307 and moves into the sleeve 303. At this time, the total length of the sleeve 303 and the positioning rod 306 gradually decreases, and the pressing plate 103 is able to 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: when the pressing plate 103 moves downward, the arc plate 304 is always in contact with the upper edge of the breast. Therefore, when the roller 202 stretches the breast, the breast tissue around the breast moves to the bottom of the pressing plate 103. The friction between the arc plate 304 and the skin tissue will hinder the resetting of the breast tissue. In addition, before the roller 202 separates from the breast, the pressing plate 103 gradually becomes horizontal from tilt under the action of the torsion spring 215. Before the breast shape rebounds, the pressing plate 103 flips over and presses down, ensuring the effectiveness of the stretching of the roller 202 and ensuring a larger contact area between the breast and the pressing plate 103, thereby increasing the reliability of the device.

[0059] Embodiment 3: This embodiment is intended to promote the solution of the problem that breast tissue is more distributed in the middle of the breast, breast tissue is piled up after the breast is squeezed by the pressing plate, and breast tissue imaging is unclear after X-ray shooting. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figures 1 to 10 The movable rod 301 is slidably mounted on the electric slider 104. A reciprocating mechanism 4100 is provided on the molybdenum target machine body 101. When the pressing plate 103 presses down the breast, the pressing plate 103 moves back and forth.

[0060] For details, 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 Fig.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 collides with 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, so that the lubricating oil in the oil storage box 407 is sprayed to the bottom of the pressing plate 103 through the oil pipe 409 and the nozzle 410, thereby reducing the friction between the pressing plate 103 and the patient's breast, reducing the discomfort caused by the pressing plate 103 pressing down on the breast and rubbing it back and forth, and improving the practicality of the device.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
