Description

Technical Field

[0001] This invention relates to the field of medical breast examination beds, specifically a medical breast ultrasound examination bed. Background Technology

[0002] The core principle of breast ultrasound is the reflection of sound waves. The ultrasound probe emits high-frequency ultrasound waves, which penetrate breast tissue. When these sound waves encounter tissues of different densities, they are reflected, refracted, and scattered. The probe receives these returned "echo" signals, and the computer processes them in real time based on information such as the intensity and time of the echoes. Finally, a two-dimensional or three-dimensional image of the inside of the breast is formed on the screen. Doctors analyze the shape, boundaries, echo intensity, and blood flow characteristics of these images to determine the health status of the breast tissue.

[0003] Chinese patent announcement CN105361909B discloses a breast ultrasound scanning detection system, including an examination bed, a scanning imaging device, and an ultrasound diagnostic instrument. The cup includes a cup body for holding tissue fluid and accommodating the breast, a cup holder fixed below the cup body, and a cup base supporting the cup body and cup holder. The cup holder and cup base are connected by a bearing, and the cup base is fixed to the examination bed. A transducer is embedded in the cup body from the outside. The upper and lower ends of the drive device are connected to the cup holder and cup base, respectively, and a positioning device is installed on the drive device. During operation, the cup body, cup holder, and transducer constitute a rotating body that rotates under the drive device. The scanning imaging device also includes a cup holder reinforcement component fixedly connected to the cup holder. The transducer's wiring is fixedly connected to the control board and, together with the control board, is fixed to the cup holder reinforcement component via a control board fixing component.

[0004] Regarding the aforementioned technologies, it is difficult to adjust the position of the transducer embedded in the cup along the radial direction of the rotation circle. Furthermore, the width of the high-frequency linear array ultrasound probe in existing medical imaging technology is generally between 38 and 50 mm. When the patient's breast volume is large, the area of ​​the circle scanned by the transducer with limited width during rotation is smaller than the projected area of ​​the breast when the patient is prone on the examination table. This makes it difficult to achieve a comprehensive examination of the breast. Moreover, when the patient is prone, the breast may not be able to fully contact the rotation plane of the probe. Due to the curvature at the edge of the breast, scanning blind spots are easily generated.

[0005] In conclusion, existing breast ultrasound examination beds do not provide sufficient scanning and examination of the patient's breast. Summary of the Invention

[0006] Based on this, the purpose of the present invention is to provide a medical breast ultrasound examination bed to solve the technical problem that existing breast ultrasound examination beds are not easy to fully scan and examine the patient's breast.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a medical breast ultrasound examination bed, comprising a bed body, an embedded drive box installed at the front end of the bed body, a rotating gear disk coaxially rotatably connected to the drive box, and a telescopic column installed above the rotating gear disk and slidably connected to a telescopic plate in a direction parallel to the diameter of the rotating gear disk, wherein a probe body is installed on the telescopic plate.

[0008] By adopting the above technical solution, a rotating toothed disk is set at the location of the breast when the patient is in a prone position. A connecting plate that can move radially parallel to the rotating toothed disk is installed on the rotating toothed disk. The probe is installed on the connecting plate, allowing the probe to adjust its position radially along the rotating toothed disk. After rotating to detect the target area, the detection range can be expanded by adjusting the position of the probe away from the center, thus achieving a full scan and detection of the patient's breast.

[0009] The present invention is further configured such that the drive box is provided with a drive gear for driving the rotating gear disk, the top surface of the rotating gear disk is fixedly connected to a mounting column, the mounting column is fixedly connected to a mounting plate, the telescopic column is fixedly connected to the mounting plate, and a slide rail is provided on the side away from the mounting plate, the telescopic plate is slidably connected to the slide rail, and is fixedly connected to the telescopic part of the telescopic column.

[0010] Preferably, a drive mechanism installed inside the bed is used to control the rotation of the drive gear, and the rotational motion of the rotating gear is achieved by the meshing of the drive gear with the rotating gear.

[0011] The present invention is further configured such that a pressure ring is provided on the edge of the top of the drive box of the bed body, and an annular film is coaxially engaged with the pressure ring.

[0012] Preferably, the annular film is used to prevent the probe body from directly contacting the patient's breast.

[0013] The present invention is further configured such that a first connecting plate is fixedly installed on the telescopic plate, and a probe body is fixedly installed on the first connecting plate. The width direction of the probe body installed on the first connecting plate is the same as the moving direction of the telescopic plate, and it can pass through the axis of the rotating gear.

[0014] Preferably, the position of the probe body's rotation radius can be adjusted by moving the telescopic plate, thereby changing the detection range of the probe body.

[0015] The invention is further configured such that a second connecting plate is fixedly installed on the telescopic plate, a rotating seat is fixedly connected to the second connecting plate, a vertical rotating shaft is rotatably connected inside the rotating seat, a first rotating block is fixedly connected to the top of the rotating shaft, a second rotating block is rotatably connected to one side of the first rotating block, the second rotating block is fixedly connected to the receiving box, a probe body is installed inside the receiving box, and an elastic mechanism is provided between the second rotating block and the first rotating block for bringing the upper end of the receiving box closer to the first rotating block.

[0016] Preferably, while adjusting the position of the probe body on the rotating circular plane, the orientation of the probe body is adjusted by rotation, causing the probe body to move to a position close to the edge of the breast. In conjunction with the elastic mechanism at the pivot of the second rotating block, blind spot detection of the breast edge is achieved.

[0017] The present invention is further configured such that, before the receiving box is rotated, the width direction of the probe body is the same as the moving direction of the telescopic plate and can pass through the axis of the rotating gear disk, and after the receiving box is rotated, the probe body rotates ninety degrees along its own central vertical axis.

[0018] Preferably, the probe body, after being rotated and adjusted in position, can make more even contact with the edge of the breast.

[0019] The invention is further configured such that a compressed spring sheet is provided on the side of the first rotating block opposite to the second rotating block at a position lower than the axis of the second rotating block, and a plug is fixedly connected to the receiving box on the same side connected to the second rotating block. A socket for cooperating with the plug is fixedly connected to the second connecting plate. The front end of the plug is provided with a chamfer. When the plug is inserted into the socket, the top surface of the receiving box returns to a horizontal state.

[0020] Preferably, the cooperation between the insertion platform and the insertion post allows the container to return to a horizontal state during reverse rotation.

[0021] The invention is further configured such that the mounting plate on the rotating gear disk has two symmetrically arranged plates, one of which is used to mount the telescopic column, while the other mounting plate is fixedly connected to a baffle. After the receiving box rotates, the baffle can contact the end of the receiving box away from the second connecting plate.

[0022] Preferably, the baffle contacts the edge of the container, making the container more stable when moving.

[0023] The invention is further configured such that when the side of the receiving box connected to the insert post is parallel to the second connecting plate, the insert post restricts the receiving box from rotating in the reverse direction, and after the receiving box rotates 90 degrees in the forward direction, it is restricted by the second connecting plate from continuing to rotate in the forward direction.

[0024] Preferably, the insertion platform and the second connecting plate are used to limit the rotation range of the receiving box, and the probe body inside the receiving box can be quickly and accurately adjusted within a preset rotation angle.

[0025] The present invention is further configured such that, after the receiving box is rotated about the axis of the second rotating block by the elastic force of the elastic mechanism, the top of the probe body is higher than the state before rotation and tilted upward toward the axis of the rotating toothed disk.

[0026] Preferably, the probe body is designed to better contact the blind area at the edge of the breast.

[0027] In summary, the present invention has the following main beneficial effects:

[0028] This invention involves placing a rotating toothed disc at the location of the breast while the patient is in a prone position. A connecting plate that can move radially parallel to the rotating toothed disc is mounted on the rotating toothed disc. The probe is mounted on the connecting plate, allowing the probe to adjust its position radially along the rotating toothed disc. After detecting the target area by rotating the disc, the detection range can be expanded by adjusting the probe's position away from the center, thus achieving a thorough scan and detection of the patient's breast.

[0029] This invention places a disc above a rotating gear and attaches a leak-proof sleeve between the disc and the probe. This effectively prevents the coupling agent from leaking into the drive box during the testing process, while ensuring that no gaps or cavitation occur between the probe and the annular film, thereby guaranteeing the testing quality.

[0030] This invention allows the probe to rotate 90 degrees by rotating the connecting housing on a horizontally movable connecting plate. This changes the probe's position from parallel to the direction of movement of the telescopic plate to perpendicular to the direction of movement of the telescopic plate. Simultaneously, the probe's tip can be tilted upwards towards the axis of the rotating gear. As the telescopic plate reciprocates and extends, the rotating gear continuously rotates, thus enabling supplementary detection of blind areas at the edge of the breast and further improving the accuracy of breast detection for patients with larger breasts.

[0031] This invention improves the stability of the container during movement by installing a baffle on the mounting column at the position corresponding to the position of the container after rotation adjustment. This ensures that the container maintains its 90-degree rotation state during the reciprocating motion along the direction of the telescopic plate after rotation adjustment.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] The embodiments of the present invention will now be described.

[0052] First embodiment:

[0053] A medical breast ultrasound examination bed, please refer to Figure 1-7 The device includes a bed frame 1, with an embedded drive box 2 installed at the front end of the bed frame 1. Specifically, the bed frame 1 is a breast ultrasound examination bed. The mattress of the examination bed is made of foam and covered with synthetic leather, which provides the examinee with the best comfort when lying prone for the examination. The synthetic leather also makes it easier for the user to clean, maintain and disinfect.

[0054] It also includes a rotating gear disk 3, which is coaxially rotatably connected to the drive box 2. The drive box 2 is equipped with a drive gear 201 for driving the rotating gear disk 3. A mounting column 4 is fixedly connected to the top surface of the rotating gear disk 3. A mounting plate 5 is fixedly connected to the mounting column 4. A telescopic column 6 is fixedly installed on the mounting plate 5 along the horizontal direction. A slide rail 601 is provided on the side of the telescopic column 6 away from the mounting plate 5. The telescopic plate 7 is slidably connected to the slide rail 601 and fixedly connected to the telescopic part of the telescopic column 6. The drive mechanism provided in the bed 1 controls the rotation of the drive gear 201. The rotational motion of the rotating gear disk 3 is realized by the meshing of the drive gear 201 with the rotating gear disk 3.

[0055] It also includes a telescopic column 6, which is installed above the rotating toothed disk 3 and is slidably connected to a telescopic plate 7 in a direction parallel to the diameter of the rotating toothed disk 3. The probe body 25 is installed on the telescopic plate 7.

[0056] Furthermore, the bed body 1 has a pressure ring 22 at the top edge of the drive box 2. The pressure ring 22 is coaxially engaged with an annular film 23. Specifically, the edge of the annular film 23 has two locking blocks, while the edge of the pressure ring 22 has two recesses for adapting to the locking blocks, which allows the annular film 23 to be installed quickly and stably. The annular film 23 is used to prevent the probe body 25 from directly contacting the patient's breast, which can prevent the probe body 25 from pinching the examinee when moving. At the same time, it can compress the breast when the examinee is lying down, so that the ultrasound penetration is better and the whole breast scan is more complete. This annular film 23 is a replaceable accessory and can be replaced according to the frequency of use.

[0057] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-7 Below the annular film 23, a first disc 20 is also provided. The bottom end of the first disc 20 contacts the top end of the mounting post 4, and a recessed part is also provided for engaging with the top end of the mounting post 4 to ensure that the first disc 20 and the rotating gear disc 3 rotate synchronously. Specifically, the first disc 20 is provided with a rectangular opening, and a leak-proof sleeve 24 is provided between the opening and the probe body 25. Both ends of the leak-proof sleeve 24 are provided with elastic rubber rings. One end is fitted onto the probe body 25, and the other end is fitted onto the opening of the first disc 20. The leak-proof sleeve 24 can effectively prevent the ultrasonic coupling agent from leaking into the drive box 2.

[0058] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-6 A first connecting plate 8 is fixedly installed on the telescopic plate 7, and a probe body 25 is fixedly installed on the first connecting plate 8. Specifically, a fixing plate 801 is rotatably connected to the first connecting plate 8. The side of the fixing plate 801 facing the probe body 25 is made of elastic material. When installing the probe body 25, the probe body 25 is first placed in the space inside the first connecting plate 8 for placing the probe body 25. After adjusting the height of the probe body 25, the fixing plate 801 is rotated and covered. The fixing plate 801 is then brought closer to the probe body 25 by the bolt mechanism at the edge of the fixing plate 801. Specifically, the fixing plate 801 passes through the bolt mechanism at a waist hole. The elastic deformation of the elastic material can press and fix the probe body 25 to prevent the probe body 25 from loosening during the detection process.

[0059] Furthermore, the probe body 25 mounted on the first connecting plate 8 has the same width direction as the telescopic plate 7 and can pass through the axis of the rotating gear 3 during telescopic movement. The position of the rotation radius of the probe body 25 can be adjusted by moving the telescopic plate 7, thereby changing the detection range of the probe body 25.

[0060] Second embodiment:

[0061] A medical breast ultrasound examination bed, please refer to Figure 1-16Based on the first embodiment, the difference from the first embodiment is that a second connecting plate 9 is fixedly installed on the telescopic plate 7, a rotating seat 12 is fixedly connected to the second connecting plate 9, a vertical rotating shaft 1301 is rotatably connected inside the rotating seat 12, a first rotating block 13 is fixedly connected to the top of the rotating shaft 1301, and a second rotating block 14 is rotatably connected to one side of the first rotating block 13. Specifically, the axis of rotation of the second rotating block 14 is orthogonal to the axis of rotation of the rotating shaft 1301.

[0062] Furthermore, the second rotating block 14 is fixedly connected to the receiving box 15, and the receiving box 15 is equipped with the probe body 25. Specifically, when installing the probe body 25, it needs to be inserted into the receiving box 15 from the bottom upward. After the probe body 25 is adjusted to the correct height, the knob 19 located on the receiving box 15 is rotated. The screw fixedly connected to the knob 19 extends towards the probe body 25, pushing the pressure plate 18 to slide in the slide groove 1501, thereby pressing and fixing the probe body 25. Similarly, the side of the pressure plate 18 facing the probe body is provided with an elastic material such as rubber. In order to avoid the pressure plate 18 interfering with the rotation of the receiving box 15, both ends of the pressure plate 18 do not exceed the range of the sides of the receiving box 15.

[0063] Furthermore, an elastic mechanism is provided between the second rotating block 14 and the first rotating block 13 to bring the upper end of the receiving box 15 closer to the first rotating block 13. While adjusting the position of the probe body 25 on the rotating circular plane, the orientation of the probe body 25 is adjusted by rotation, so that the probe body 25 moves to a position close to the edge of the breast. In conjunction with the elastic mechanism at the rotating shaft of the second rotating block 14, blind spot detection of the breast edge is achieved.

[0064] Specifically, in this embodiment, a compressed spring piece 1401 is provided on the side of the first rotating block 13 and the second rotating block 14 opposite each other at a position lower than the axis of the second rotating block 14. After the insertion post 16 and the insertion platform 17 are separated, the compressed spring piece 1401 can push the second rotating block 14 to rotate, so that the top of the second rotating block 14 is close to the first rotating block 13. In other disclosed embodiments, a torsion spring can also be provided in the rotating shaft of the second rotating block 14.

[0065] For details regarding the above embodiments, please refer to [link / reference]. Figure 8-9 The difference from the first embodiment is that in this embodiment, a second disk 21 is used instead of the first disk 20 in the first embodiment. Specifically, the width of the rectangular opening of the second disk 21 is greater than the width of the rectangular opening of the first disk 20, so as to ensure that the probe body 25 can still move smoothly after rotating ninety degrees.

[0066] For details regarding the above embodiments, please refer to [link / reference]. Figure 10-13The rotating gear plate 3 has two symmetrical mounting plates 5. One mounting plate 5 is used to mount the telescopic column 6, while the other mounting plate 5 is fixedly connected to a baffle 10. After the receiving box 15 rotates, the baffle 10 can contact the end of the receiving box 15 away from the second connecting plate 9. The baffle 10 contacts the edge of the receiving box 15, making the receiving box 15 more stable when moving. Specifically, when the receiving box 15 moves to the area corresponding to the baffle 10, the probe body 25 performs the detection of the breast edge position. The receiving box 15 needs to move back and forth along the moving direction of the telescopic plate 7. At this time, the baffle 10 and the second connecting plate 9 cooperate to effectively prevent the receiving box 15 from rotating along the rotation axis 1301. When the receiving box 15 is reset, the telescopic plate 7 needs to be reset first so that the baffle 10 cannot interfere with the rotation of the receiving box 15.

[0067] For details regarding the above embodiments, please refer to [link / reference]. Figure 10-14 Before the housing box 15 is rotated, the width direction of the probe body 25 is the same as the moving direction of the telescopic plate 7, and it can pass through the axis of the rotating gear 3. After the housing box 15 is rotated, the probe body 25 rotates ninety degrees along its own central vertical axis, so that the probe body 25 after the rotation and adjustment can more evenly contact the edge of the breast.

[0068] Specifically, the receiving box 15 is fixedly connected to a post 16 on the same side as the second rotating block 14. The second connecting plate 9 is fixedly connected to a platform 17 for cooperating with the post 16. The front end of the post 16 is provided with a chamfer. When the post 16 is inserted into the platform 17, the top surface of the receiving box 15 returns to a horizontal state. The cooperation between the platform 17 and the post 16 enables the receiving box 15 to return to a horizontal state during the reverse rotation.

[0069] Furthermore, when the side of the receiving box 15 connected to the insertion post 16 is parallel to the second connecting plate 9, the insertion platform 17 restricts the receiving box 15 from rotating in the reverse direction. After the receiving box 15 rotates 90 degrees in the forward direction, it is restricted by the second connecting plate 9 and cannot continue to rotate in the forward direction. The insertion platform 17 and the second connecting plate 9 are used to limit the rotation range of the receiving box 15. The probe body 25 inside the receiving box 15 can be adjusted quickly and accurately within the preset rotation angle.

[0070] For details regarding the above embodiments, please refer to [link / reference]. Figure 10-13 , Figure 16 After the housing 15 rotates around the axis of the second rotating block 14 under the elastic force of the elastic mechanism, the top of the probe body 25 is higher than before it rotates and tilts upward toward the axis of the rotating toothed disk 3, so that the probe body 25 can better contact the blind area of ​​the breast edge.

[0071] In practical operation, this invention:

[0072] One end of the leak-proof sleeve 24 is attached to the probe body 25, and the other end is attached to the opening of the second disc 21. After covering the second disc 21, the leak-proof sleeve 24 is pressed down to expose the probe body 25. Sufficient ultrasonic coupling agent is applied to the probe body 25. Then, ultrasonic coupling agent is applied to the central area of ​​the side of the annular film 23 that contacts the subject. The side of the annular film 23 that contacts the probe body 25 is fully coated with ultrasonic coupling agent. Then, the annular film 23 is snapped onto the pressure ring 22.

[0073] With the operator's assistance, the examinee lies prone, aligns the nipple of the breast to be examined with the center of the annular membrane 23, and then lies down naturally, placing the breast on the annular membrane 23. It is important to keep the breast as flat as possible. The examinee turns their head to the opposite side, and the arm on the side being examined hangs down naturally. The other arm is placed on the side of the body according to the shape of the chest or hangs down naturally.

[0074] The drive mechanism inside the bed 1 controls the rotation of the rotating gear disk 3 to realize the rotational movement of the probe body 25. After the probe body 25 completes the detection work on the rotating circular surface, the telescopic column 6 pushes the telescopic plate 7 to slide out, allowing the probe body 25 to move to a position further away from the center of rotation. The rotating gear disk 3 continues to rotate to realize the detection of the breast over a larger area by the probe body 25.

[0075] When a blind spot test is required on the edge of the breast, after the test of the rotating circular surface is completed, the telescopic column 6 retracts first to reset the telescopic plate 7, and then the bidirectional motor 11 drives the receiving box 15 to rotate 90 degrees in the forward direction. When the insertion column 16 exits from the insertion platform 17, the receiving box 15 is in a state of tilting upward towards the axis of the rotating gear 3 due to the elastic force of the elastic mechanism at the shaft of the second rotating block 14. Then the telescopic column 6 extends to move the receiving box 15 to the area where the baffle 10 is located. At this time, the receiving box 15 is restricted by the baffle 10 and the second connecting plate 9 and cannot rotate along the rotating axis 1301.

[0076] When detecting the edge of the subject's breast, the telescopic column 6 first extends, causing the probe body 25 to move beyond the breast area, and then retracts in the opposite direction. During the retraction process, the probe body 25 contacts the annular film 23 corresponding to the breast edge. The elastic mechanism at the pivot of the second rotating block 14 ensures that the probe body 25 maintains contact with the annular film 23 corresponding to the breast edge during the movement. Then, the gear disk 3 rotates to a preset angle, and the telescopic column 6 repeats the extension and retraction. This cycle is repeated to achieve blind spot detection of the breast edge.

[0077] After each inspection, please clean the annular film 23 with alcohol or water. If the annular film 23 cannot be cleaned, please replace it with a new one.

[0078] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
