Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a body positioning support device for a mammography machine used in radiology. Background Technology

[0002] A mammogram is a medical research instrument used in clinical medicine. It can diagnose early-stage breast cancer lesions, breast hyperplasia, and other diseases. It produces clear images, clearly displaying breast structure, and is characterized by its comprehensiveness, intuitiveness, and ease of operation. For breast cancer patients, it can be used for follow-up examinations after radiotherapy and chemotherapy, and for regular monitoring of the healthy breast.

[0003] Current detection methods typically involve the patient standing naturally, with both breasts placed on the mammography machine's support plate according to the required imaging positions (routine bilateral nipple-tail position + internal and external oblique position) for compression imaging. However, because the examination time is relatively long, patients are prone to body swaying, affecting the imaging results; moreover, some patients may not be able to maintain a standing posture for an extended period due to physical reasons.

[0004] Chinese patent application CN 114403910 B discloses a mammography machine positioning support device for radiology, including a base, a seat, and a support structure. This device allows patients to maintain a seated position during imaging and also enables them to straighten their chests to bring their breasts closer to the mammography machine. However, this support device still has the following problems in use:

[0005] 1. During routine mammography examinations, patients are usually in a natural standing position. Therefore, patients should be able to stand during the examination as much as possible, and only sit when necessary. However, this support device cannot fix the patient's body when standing, and cannot meet the requirements of both standing and sitting positions.

[0006] 2. The support device can rotate the soft pad through the cam to help the patient maintain the chest-opening posture. However, the support device cannot fix the patient's shoulders or other parts of the upper body. The patient may also experience involuntary swaying or movement when the chest is open for a long time, which will affect the shooting effect.

[0007] 3. The seat of this support device cannot rotate or move on a flat surface. In order to ensure that the patient's breast can be placed on the mammography machine, the seat needs to face the mammography machine and be close to it. As a result, it is inconvenient for the patient to get on and off the seat.

[0008] 4. The support device lacks a structure to support the patient's lower back, which can easily cause stiffness and fatigue in the lower back when the patient maintains an upright posture for a long time. Summary of the Invention

[0009] To address the aforementioned problems, this invention aims to provide a body positioning support device for a mammography machine in radiology. This device can both fix the patient's shoulders in a normal standing position for convenient examination and allow the patient to undergo mammography in a seated position. The seat position is rotatable and movable, making it easy for the patient to get on and off the seat.

[0010] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0011] A positioning support device for a mammography machine in radiology includes a movable guide rail, on which a mounting base is slidably connected. The device is characterized in that: a standing plate is rotatably connected to the mounting base, a back plate is fixedly mounted on the top of one side of the standing plate, two sets of shoulder fixing components are symmetrically and slidably connected on the back plate, and a first driving component for driving the two sets of shoulder fixing components to move is installed on the side of the back plate away from the standing plate.

[0012] Furthermore, each of the shoulder fixing components includes a movable rod, and the back plate has a first movable through hole that matches the movable rod. The front end of the movable rod is movably connected to an arc-shaped limiting rod, and the bottom of the limiting rod movably passes through the first movable through hole.

[0013] Furthermore, the first drive assembly includes a telescopic rod mounted on the back plate, the output end of the telescopic rod being fixedly connected to a first fixing plate, the first fixing plate being fixedly connected to the rear ends of the two movable rods; a second drive assembly for driving the two limiting rods to rotate is installed inside the first fixing plate.

[0014] Furthermore, the end of the moving rod near the limiting rod is rotatably connected to a first rotating shaft, and the limiting rod is fixedly connected to the first rotating shaft; the second driving assembly includes a bidirectional driving motor, and both output ends of the bidirectional driving motor are connected to a second rotating shaft, and the two second rotating shafts are connected to the two first rotating shafts in a transmission connection.

[0015] Furthermore, a first gear is fixedly fitted on each of the first rotating shafts, and a second gear is fixedly fitted on each of the second rotating shafts. The first gear and the second gear are connected by a first chain. A balance bar is also fixed inside the moving rod, and a collar is provided at the end of the balance bar. The collar is rotatably fitted on the first rotating shaft.

[0016] Furthermore, an adjustable lumbar pad is slidably connected to the back plate. The lumbar pad includes a lumbar pad body, and side wings are provided on both sides of the lumbar pad body. The rear side of the lumbar pad body slides through the back plate via a connecting block. A second fixing plate is fixedly provided on the rear side of the connecting block. The first fixing plate and the second fixing plate are fixedly connected by two connecting plates. A third driving component for driving the deformation of the side wings is provided in the second fixing plate.

[0017] Furthermore, the third drive assembly includes a third rotating shaft rotatably connected within the second fixed plate. Two first pulleys and two fourth gears are fixedly sleeved on the third rotating shaft. Each fourth gear has a second rack meshing at its bottom. The second rack passes through the second fixed plate and the back plate, and the front ends of the two second racks are respectively movably connected to the two side wings. The third rotating shaft is connected to the two second rotating shafts in a transmission manner.

[0018] Furthermore, a seat plate is movably connected to the back plate, and a hidden groove matching the seat plate is provided on the back plate. The hidden groove is located below the shoulder fixing component, and a fourth drive component for driving the seat plate to rotate is provided between the mounting base and the back plate.

[0019] Furthermore, a second drive motor is installed on the top of the mounting base. The output end of the second drive motor is fixedly connected to the standing plate. An arc-shaped rotating groove is provided on the top surface of the mounting base. The rotating groove is circular with the center of the output end of the second drive motor as the center, and the depth of the rotating groove gradually decreases from the outside to the inside.

[0020] Furthermore, the fourth drive assembly includes a drive rod movably connected within the rotating groove. The top of the drive rod extends through the back plate, and the top of the drive rod near the seat plate has teeth. The seat plate is rotatably connected within the hidden groove via a fourth rotating shaft, and a third gear matching the teeth is fixedly sleeved on the fourth rotating shaft. A limiting groove matching the drive rod is provided on the back plate, and a return spring is fixed between the top of the limiting groove and the top of the drive rod.

[0021] The beneficial effects of this invention are: compared with the prior art, the improvement of this invention lies in that...

[0022] 1. The body position support device of the present invention hides and stores a seat on the back panel. When the seat is stored, the patient can stand on the standing board with his back against the back panel and maintain a normal standing posture for mammography. If the patient is not comfortable maintaining a standing posture for a long time, the seat can be adjusted to be parallel to the standing board so that the patient can maintain a sitting posture for mammography. This makes it suitable for patients in different situations.

[0023] 2. In the process of adjusting the seat to be parallel with the standing board, the body positioning support device of the present invention drives the entire standing board and backboard to rotate 90 degrees via the second drive motor. During the rotation, the drive rod rotates in the rotation groove. Due to the structure of the rotation groove being deeper on the outside and shallower on the inside, the drive rod moves upward while rotating in the rotation groove, thereby driving the third gear to rotate through the teeth on the drive rod. When the third gear rotates, it drives the entire seat to rotate. That is, when the seat is adjusted to be parallel with the standing board, the entire structure formed by the standing board and backboard will rotate 90 degrees, so that the patient located on the side of the moving guide rail can easily get on and off the seat. When the seat is stored in the hidden groove, and the patient stands on the standing board for examination, there is no need to rotate the angle of the standing board and backboard, and the patient can directly stand on the standing board from the side.

[0024] 3. The body positioning support device of this invention has two shoulder fixation components slidably mounted on the back plate. The shoulder fixation components are moved up and down by a telescopic rod, which can fix the shoulders of patients who are standing or sitting on the seat, as well as patients of different heights. The patient maintains an upright posture, and the shoulders are fixed to ensure that the patient's shoulders do not shake, thereby improving the accuracy of the examination. The limiting rod in the shoulder fixation component can be adjusted at any angle under the cooperation of the bidirectional drive motor and the second rotating shaft, the first rotating shaft, and the first gear and the second gear, thus making it suitable for patients of different body types.

[0025] 4. The body position support device of this invention also has a lumbar pad that moves up and down on the back plate, which can support the patient's waist and prevent the patient from experiencing soreness in the waist when maintaining the same posture for a long time. The lumbar pad moves up and down with the shoulder fixation component, and while the two limiting rods on the shoulder fixation component rotate, they can drive the second rack to move back and forth through the transmission connection between the third rotating shaft and the second rotating shaft. This causes the two side wings on the lumbar pad to rotate, wrapping around the patient's waist on both sides, further fixing the patient and improving the support effect on the patient's waist, reducing the patient's discomfort.

Detailed Implementation

[0048] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0049] Example 1:

[0050] See attached document Figure 1-8 As shown, a positioning support device for a mammography machine in radiology includes a movable guide rail 1, a mounting base 2 slidably connected to the movable guide rail 1, a standing plate 3 rotatably connected to the mounting base 2, a back plate 4 fixedly mounted on the top of one side of the standing plate 3, two sets of shoulder fixing components symmetrically and slidably connected to the back plate 4, and a first driving component for driving the movement of the two sets of shoulder fixing components is installed on the side of the back plate 4 away from the standing plate 3.

[0051] Specifically, the movable guide rail 1 has two guide rail grooves 101, and a lead screw 24 is rotatably mounted in each guide rail groove 101 via a bearing. Each lead screw 24 is provided with a matching lead screw nut 2401. One end of the lead screw 24 is rotatably connected to the inner wall of the corresponding guide rail groove 101, and the other end of the lead screw 24 is fixedly provided with a fifth rotating shaft 34. One end of the fifth rotating shaft 34 is rotatably connected to the inner wall of the corresponding guide rail groove 101 via a bearing, and the other end of the fifth rotating shaft 34 rotatably passes through the movable guide rail 1 via a bearing. A third drive motor 25 is installed outside the movable guide rail 1. The fifth rotating shaft 34 is located outside the movable guide rail 1. The end of the 4 is fixedly connected to the output end of the third drive motor 25. The two fifth rotating shafts 34 are each fitted with a second pulley 35, and the two second pulleys 35 are connected by a second transmission belt 36. The mounting base 2 is fixedly connected to the top of the two lead screw nuts 2401. When the third drive motor 25 rotates, it drives the fifth rotating shaft 34 connected to it to rotate. Then, through the mutual cooperation between the two second pulleys 35 and the second transmission belt 36, it drives another fifth rotating shaft 34 to rotate in the same direction. When the two fifth rotating shafts 34 rotate, they drive the two lead screws 24 to rotate synchronously, thereby driving the two lead screw nuts 2401 to move synchronously, and finally driving the mounting base 2 to move.

[0052] The standing plate 3 can be mounted on the mounting base 2 by rotating the motor, and the standing plate 3 and the back plate 4 form an integral L-shaped structure.

[0053] Furthermore, each of the shoulder fixing components includes a movable rod 5. The back plate 4 has a first movable through hole 401 matching the movable rod 5. The movable rod 5 can move up and down within the corresponding first movable through hole 401. An arc-shaped limiting rod 6 is movably connected to the front end of the movable rod 5. A connecting rod 601 is fixedly mounted on one end of the limiting rod 6 near the movable rod 5. A first rotating shaft 9 is vertically fixed within the connecting rod 601. A clearance groove 501 is formed on one end of the movable rod 5 near the limiting rod 6. The first rotating shaft 9 is rotatably connected within the clearance groove 501, and both ends of the first rotating shaft 9... All ends are located inside the movable rod 5; the rotation of the first rotating shaft 9 can realize the rotation of the limiting rod 6 at any angle. The bottom of the limiting rod 6 moves through the first movable through hole 401, so that the size of the space enclosed between the limiting rod 6 and the back plate 4 can be adjusted arbitrarily, which is convenient for fixing the shoulder of patients of different body types. When fixing the patient's shoulder, first rotate the limiting rod 6 to the top, then place the patient's shoulder on the limiting rod 6 and close to the back plate 4, rotate the limiting rod 6 in the opposite direction, pass the limiting rod 6 through the patient's armpit, and then pass it into the first movable through hole 401 to fix the patient's shoulder.

[0054] Furthermore, the first driving assembly includes a telescopic rod 7 installed on the top of the back plate 4 away from the standing plate 3. The output end of the telescopic rod 7 is fixedly connected to a first fixing plate 8, which is fixedly connected to the rear ends of the two moving rods 5. The telescopic rod 7 is an electric telescopic rod, which can synchronously drive the first fixing plate 8 and the two moving rods 5 to move up and down. A second driving assembly for driving the two limiting rods 6 to rotate is installed inside the first fixing plate 8. The second driving assembly includes a bidirectional drive motor 10, whose two output ends are perpendicular to the moving rods 5, and both output ends are connected to a second rotating shaft 11. The first fixing plate 8 has mounting slots for mounting the bidirectional drive motor 10 and the second rotating shaft 11. The end of shaft 11 away from the bidirectional drive motor 10 is rotatably connected to the mounting slot; a first gear 12 is fixedly sleeved on each of the first rotating shafts 9, and a second gear 13 is fixedly sleeved on each of the second rotating shafts 11. The first gear 12 and the second gear 13 are connected by a first chain 14; the moving rod 5 and the first fixed plate 8 are also provided with mounting slots for the first chain 14 to pass through, ensuring the normal operation of the first gear 12, the second gear 13 and the first chain 14; in order to improve the stability of the operation of the first gear 12, the second gear 13 and the first chain 14, a balance rod 15 is also fixedly installed in the moving rod 5. The end of the balance rod 15 away from the moving rod 5 is fixedly connected to the first fixed plate 8, and the end of the balance rod 15 is provided with a collar 16, which is rotatably sleeved on the first rotating shaft 9. When the bidirectional drive motor 10 is working, it drives the two second rotating shafts 11 to rotate synchronously. Under the action of the first gear 12, the second gear 13 and the first chain 14, the second rotating shaft 11 drives the first rotating shaft 9 to rotate, thereby realizing the rotation of the limit rod 6.

[0055] The working principle of the mammography machine positioning support device in this embodiment is as follows: When using the positioning support device, the patient stands on the standing board 3, with their chest out and back pressed against the backboard. The height of the moving rod 5 is adjusted by the telescopic rod 7 so that the moving rod 5 is just above the patient's shoulder. Then, the bidirectional drive motor 10 is started, driving the two second rotating shafts 11 to rotate synchronously. Under the action of the first gear 12, the second gear 13 and the first chain 14, the second rotating shaft 11 drives the first rotating shaft 9 to rotate, thereby realizing the rotation of the limiting rod 6. The limiting rod 6 rotates until the patient's shoulder is locked between the limiting rod 6 and the... The backplate 4 stops; then the third drive motor 25 is started, which drives the fifth rotating shaft 34 connected to it to rotate. Through the cooperation between the two second pulleys 35 and the second transmission belt 36, another fifth rotating shaft 34 is driven to rotate in the same direction. At the same time, the two fifth rotating shafts 34 rotate, which drives the two lead screws 24 to rotate synchronously, thereby driving the two lead screw nuts 2401 to move synchronously. Finally, the mounting base 2, the standing plate 3 and the backplate 4 are moved as a whole, so that the patient is close to the mammography machine. The height of the plate on the mammography machine is adjusted, and the patient's chest is placed on the plate of the mammography machine for examination.

[0056] Example 2:

[0057] Based on Embodiment 1, in order to reduce the discomfort in the lower back when the patient maintains a standing posture for a long time, an adjustable lumbar support 26 is slidably connected to the back panel 4. The lumbar support 26 is located between the two shoulder fixation components, as shown in the attached figure. Figure 9-12 As shown.

[0058] The lumbar pad 26 includes a lumbar pad body 2601, with side wings 2602 on both sides of the lumbar pad body 2601. The lumbar pad body 2601 and the two side wings 2602 form an integral structure. This lumbar pad 26 structure can be an existing elastic lumbar pad, which can be bent and deformed. The rear side of the lumbar pad body 2601 slides through the back plate 4 via a connecting block 27. The back plate 4 has a second moving through hole 404 for the connecting block 27 to move up and down. A second fixing plate 28 is fixedly provided on the rear side of the connecting block 27. The second fixing plate 28 is located on the rear side of the back plate 4, and the first fixing plate 8 and the second fixing plate 28 are fixedly connected by two connecting plates 29 to form an integral structure. Under the action of the telescopic rod 7, the whole structure can move up and down, thereby driving the shoulder fixing component and the lumbar pad 26 to move up and down synchronously. The second fixing plate 28 is provided with a third driving component for driving the deformation of the side wings 2602.

[0059] The third drive assembly includes a third rotating shaft 30 rotatably connected within the second fixed plate 28. The second fixed plate 28 has a mounting groove. Both ends of the third rotating shaft 30 are rotatably mounted within the mounting groove via bearings. Two first pulleys 31 and two fourth gears 32 are fixedly sleeved on the third rotating shaft 30. Three pulleys 37 are fixedly sleeved on both second rotating shafts 11. Each first pulley 31 and its corresponding third pulley 37 are connected via a first transmission belt 38. A second rack 33 meshes with the bottom of each fourth gear 32. The second rack 33 passes through the second fixed plate 28 and the back plate 4, and the front ends of the two second racks 33 are respectively hinged to the two side wings 2602.

[0060] In this embodiment, when the lumbar pad is in use, the telescopic rod 7 first drives the shoulder fixing component and the lumbar pad 26 to move up and down synchronously to a suitable position. When the bidirectional drive motor 10 and the second rotating shaft 11 drive the limiting rod 6 to rotate, the second rotating shaft 11 drives the third rotating shaft 30 to rotate through the cooperation of the first pulley 31, the third pulley 37 and the first transmission belt 38. The rotation of the third rotating shaft 30 drives the fourth gear 32 on it to rotate, which in turn drives the second rack 33 to move back and forth. When the second rack 33 moves back and forth, it will drive the two side wings 2602 of the lumbar pad 26 to rotate, thereby wrapping the two side wings 2602 around the patient's waist, improving the fixation effect on the patient's waist, and reducing the discomfort of the waist when the patient maintains the same posture for a long time.

[0061] Example 3:

[0062] Based on Embodiment 1 or Embodiment 2, to facilitate examinations for patients whose legs cannot maintain standing for extended periods, a seat 17 is movably connected to the backrest 4. The backrest 4 has a hidden groove 402 matching the seat 17, located below the shoulder fixation assembly. A fourth drive assembly for driving the seat 17 to rotate is provided between the mounting base 2 and the backrest 4, as shown in the attached figure. Figure 13-21 As shown. By rotating the seat 17, the seat 17 can be stored in the hiding slot 402. At this time, the entire back panel 4 is on the same plane. When the patient needs to sit on the seat 17 for examination, the seat 17 can be rotated out from the hiding slot 402.

[0063] Specifically, a second drive motor 18 is installed on the top of the mounting base 2. The output end of the second drive motor 18 is fixedly connected to the standing plate 3. The second drive motor 18 drives the entire standing plate 3 and back plate 4 to rotate, so that the seat plate 17 can face the side of the moving guide rail 1, making it convenient for the patient to sit on the seat plate 17. An arc-shaped rotating groove 19 is opened on the top surface of the mounting base 2. The rotating groove 19 is circular with the center of the output end of the second drive motor 18 as the center, and the depth of the rotating groove 19 gradually decreases from the outside to the inside.

[0064] The fourth drive assembly includes a drive rod 20 movably connected within the rotating groove 19. The bottom surface of the drive rod 20 matches the shape of the rotating groove 19, and the drive rod 20 contacts but is not connected to the rotating groove 19. The top of the drive rod 20 penetrates the back plate 4, and the top of the drive rod 20 is provided with teeth 21 on the side near the seat plate 17. A fourth rotating shaft 1701 is fixedly sleeved inside the seat plate 17, and both ends of the fourth rotating shaft 1701 penetrate the seat plate 17. Both ends of 1701 are rotatably connected to the hidden groove 402; a third gear 22 matching the teeth 21 is fixedly sleeved on the fourth rotating shaft 1701; a partition groove corresponding to the third gear 22 is opened on the seat plate 17, which does not affect the rotation of the third gear 22; a limiting groove 403 matching the drive rod 20 is opened on the back plate 4, the limiting groove 403 is connected to the hidden groove 402, and a return spring 23 is fixed between the top of the limiting groove 403 and the top of the drive rod 20.

[0065] In this embodiment, the seat 17 is hidden in the concealed groove 402 when not in use. When needed, the second drive motor 18 is activated, causing the standing plate 3 and back plate 4 to rotate. Simultaneously, the drive rod 20 rotates within the rotating groove 19. Due to the decreasing depth of the rotating groove 19, the drive rod 20 moves upwards during rotation. As the drive rod 20 moves upwards, it drives the third gear 22 on the fourth rotating shaft 1701 to rotate, thereby causing the fourth rotating shaft 1701 and the seat 17 to rotate. This allows the seat 17 to rotate from the concealed groove 402 to be parallel with the standing plate 3, and the entire standing plate 3 and back plate 4 also rotate 90 degrees, so that the seat 17 faces the side of the moving guide rail, making it convenient for the patient to sit on the seat 17. It should be noted that the rotation angle of the fourth rotating shaft 1701 is 90 degrees. Once the seat 17 is parallel to the standing plate 3, the seat 17 will not continue to rotate.

[0066] After the patient sits on the seat 17, the entire standing board 3 and back board 4 need to be rotated to face the end of the moving guide rail 1. At this time, due to the patient's own weight, the fourth rotating shaft 1701 cannot rotate in the opposite direction, and the third gear 22 remains stationary. The third gear 22 supports and limits the teeth 21 on the drive rod 20, so that the drive rod 20 will not move downward. At this time, the second drive motor 18 is controlled to rotate in the opposite direction to adjust the angle of the standing board 3 and back board 4. The drive rod 20 rotates along the direction of the rotating groove 19, but will not move downward.

[0067] After the patient's examination is completed, the standing board 3 and back board 4 are rotated again so that the seat board 17 faces the side of the moving guide rail 1. The patient gets off the seat board 17. At this time, the drive rod 20 contacts the highest position of the rotating groove 19. At this time, the seat board 17 is not affected by the patient's gravity. When the second drive motor 18 rotates in the opposite direction, under the action of the return spring 23, the drive rod 20 rotates and moves downward, thereby driving the seat board 17 to rotate into the hidden groove 402 for storage.
