Description

Technical Field

[0001] The utility model belongs to the technical field of medical detection assistance, and specifically relates to a support device for breast magnetic resonance imaging. Background Art

[0002] At present, magnetic resonance imaging (MRI), as an imaging modality with high resolution and no radiation, has been widely applied in the screening of breast lumps, identification of early-stage cancers, and postoperative follow-up processes. To ensure image quality, breast magnetic resonance imaging usually requires the subject to take a prone position, allowing the breasts to hang naturally and be placed inside the coil, so as to reduce artifact interference and improve imaging accuracy. Therefore, the breast positioning and support device matched with the magnetic resonance examination bed plays an important role in clinical detection.

[0003] Most of the existing support devices for breast magnetic resonance imaging adopt a fixed structure, generally only providing a simple prone position support function, and cannot be flexibly adjusted according to patients of different body types or specific examination items, which easily causes patient discomfort, and further affects the cooperation degree and image stability. Some devices are not provided with a height-adjustable structure, resulting in insufficient fit between the breast and the examination hole when the patient is in a prone position, causing breast compression or suspension and thus generating image artifacts. In addition, for male breast examination scenarios, the traditional structure does not perform sealable treatment on the hollowed-out holes, which easily leads to privacy exposure and physical discomfort, limiting the versatility and humanistic adaptability of the equipment.

[0004] In summary, the existing support devices for breast magnetic resonance imaging have the following technical problems: first, the structure lacks flexibility, the height of the prone support platform cannot be adjusted, and it is difficult to meet the examination needs of patients with different body types; second, there is no openable and closable examination hole structure, which cannot be automatically opened or closed according to the gender of the examined subject, easily leading to poor examination experience and privacy exposure problems. Contents of the Utility Model

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a support device for breast magnetic resonance imaging, which can realize a support device for breast magnetic resonance imaging with an adjustable structure, convenient operation and a wide range of applicable subjects, so as to improve the adaptability and comfort of breast imaging examination.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a support device for breast magnetic resonance imaging, comprising a base plate and a lifting support plate, wherein the base plate is placed on magnetic resonance equipment, four corners of the top of the base plate are each provided with a vertical cylinder, the lifting support plate is arranged above the base plate, four corners of the bottom of the lifting support plate are each provided with a support column, and the bottom of the support column slides inside the vertical cylinder;

[0007] The upper surface of the lifting support plate has a centrally concave curved structure. One end of the upper surface of the lifting support plate has a hollow hole. A hole sealing mechanism is installed at the bottom of the lifting support plate. The hole sealing mechanism is used to seal the hollow hole.

[0008] The lifting support plate is hinged to a waist support inclined plate on the side opposite to the hollow hole. The waist support inclined plate is inclined to support the waist.

[0009] Furthermore, a bidirectional screw is rotatably installed at the bottom between the two vertical cylinders on the same side. A knob is installed at the end of the bidirectional screw, and sliders are symmetrically screwed onto the surface of the bidirectional screw. The two sliders rotate on different thread surfaces of the bidirectional screw respectively.

[0010] Furthermore, the bottom of the lifting support plate is symmetrically provided with protrusions, and the top of the slider is hinged with a connecting rod, with the tops of the two connecting rods on the same side both hinged to the protrusions.

[0011] Furthermore, one end of each of the two bidirectional screws is provided with a belt drive mechanism, which is used to make the two bidirectional screws rotate synchronously.

[0012] Furthermore, the bottom of the lifting support plate is symmetrically provided with sliding grooves on both sides, and the hole sealing mechanism includes a sliding plate that slides between the two sliding grooves, with space left between the sliding plate and the lower surface of the lifting support plate.

[0013] Furthermore, the lower surface of the skateboard is symmetrically provided with fixing cylinders, and two fixing cylinders are slidably penetrated by fixing rods. A sealing arc plate is provided between the tops of the two fixing rods. The sealing arc plate is placed in the space between the skateboard and the lifting support plate, and the sealing arc plate is adapted to the internal size of the hollow hole.

[0014] Furthermore, a connecting crossbar is provided between the bottoms of the two fixed rods, and a spring is sleeved on the surface of the fixed rod. The spring is placed inside the fixed cylinder and applies an upward thrust to the sealing arc plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, a vertical cylindrical structure is set on the base plate, and a supporting column is set at the bottom of the lifting support plate to cooperate with it. A height adjustment mechanism is constructed using components such as bidirectional screws, sliders, and connecting rods. This allows for precise vertical adjustment of the lifting support plate, enabling the breast perforation hole to adapt to the natural sagging position of the breasts of patients with different body types. This solves the problem in the prior art where the support device has a fixed height and cannot adapt to different patient body types, resulting in the breast being suspended or compressed. It also improves the fitting accuracy between the breast imaging area and the magnetic resonance equipment coil, avoids image artifacts caused by positional deviations, and improves imaging quality.

[0017] In this invention, the lifting support plate is provided with a concave curved surface structure and is combined with a hinged lumbar support inclined plate, which can support the patient's chest, abdomen and waist, enhance the postural stability during the prone process, improve the phenomenon that patients are prone to fatigue or displacement due to planar support in traditional devices, effectively reduce the discomfort caused by long-term examination, help patients maintain long-term static cooperation, and further ensure the image continuity and integrity of magnetic resonance examination.

[0018] In this invention, a perforated hole is provided on the lifting support plate as a breast imaging window, and a sliding hole sealing mechanism is provided below it. The perforated hole can be controlled to be opened and closed by components such as a sliding plate, a sealing arc plate, a fixing rod, and a spring. The imaging hole can be selectively opened or blocked according to the gender of the examinee, which solves the problems of poor versatility of existing support devices and lack of privacy protection when male examinees are examined. The spring structure can drive the sealing arc plate to automatically reset and fit, and the closed state is flat and without protrusions, which improves the comfort and humanistic care of the examination experience.

[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] Example 1

[0031] refer to Figures 1-6 As shown, a support device for breast magnetic resonance imaging includes a base plate 1 and a lifting support plate 2. The base plate 1 is placed on the magnetic resonance equipment and serves as the connection base between the overall device and the magnetic resonance examination table. Vertical cylinders 11, hollow cylindrical structures, are installed at the four corners of the top of the base plate 1 to accommodate support columns 22 and provide guiding support. The lifting support plate 2 is placed above the base plate 1, and support columns 22 are provided at the four corners of the bottom of the lifting support plate 2. The support columns 22 can slide vertically within the cylinders 11 to achieve height adjustment, avoiding problems caused by poor fit between the breast and the imaging aperture due to different patient body shapes. The upper surface of the lifting support plate 2 has a centrally concave curved structure. The structure allows the chest and abdomen to fit naturally when the examinee is prone, reducing pressure discomfort and stabilizing the examination posture. One end of the upper surface of the lifting support plate 2 has a perforated hole 21, which is a reserved window for breast imaging and is sized to match the structure of the human breast. A hole sealing mechanism 4 is installed at the bottom of the lifting support plate 2. The hole sealing mechanism 4 is used to cover the perforated hole 21 when breast examination is not being performed, improving the versatility and privacy protection function of the device. A waist support inclined plate 3 is hinged to the side of the lifting support plate 2 away from the perforated hole 21. The waist support inclined plate 3 is inclined and located longitudinally at the lower edge of the lifting support plate 2 to support the waist and relieve muscle pressure fatigue caused by long-term prone position.

[0032] refer to Figures 2-4 As shown, a bidirectional screw 12 is rotatably mounted at the bottom between the two vertical cylinders 11 on the same side via a bearing assembly. The bidirectional screw 12 has left and right threads in the middle, which can realize the synchronous movement of the two sliders 14 towards or away from each other. A knob 13 is externally mounted on one end of the bidirectional screw 12. The knob 13 is used to manually adjust the rotation of the bidirectional screw 12 to adjust the height of the lifting support plate 2. Sliders 14 are symmetrically screwed onto the surface of the bidirectional screw 12. The sliders 14 adopt a nut sleeve structure and are screwed onto the left and right threaded sections of the bidirectional screw 12 respectively. The rotation of the bidirectional screw 12 realizes linear movement in the centripetal or centrifugal direction.

[0033] refer to Figures 3-5As shown, the bottom of the lifting support plate 2 is symmetrically provided with protrusions 23, which are structural reinforcements and serve as mounting hinge points for the connecting rod 15. The top of the slider 14 is hinged to the connecting rod 15 via a pin structure. The connecting rod 15 is a rigid tie rod, and its length matches the sliding stroke of the lifting support plate 2. The tops of the two connecting rods 15 on the same side are both hinged to the protrusions 23, forming a stable double-hinged connection mechanism. When the bidirectional screw 12 rotates and drives the slider 14 to move, the connecting rod 15 synchronously drives the lifting support plate 2 to rise and fall as a whole, thereby adapting to the height and body shape of different patients and improving examination efficiency and image quality.

[0034] refer to Figure 4 As shown, a belt drive mechanism 16 is provided at one end of each of the two bidirectional screws 12. The belt drive mechanism 16 includes a drive belt, a pulley, and a bearing housing assembly. The belt drive mechanism 16 is used to transmit the rotational force of one bidirectional screw 12 to the other bidirectional screw 12 through the belt, thereby realizing the synchronous rotational movement of the two bidirectional screws 12. This structure can maintain the horizontal stability of the lifting support plate 2 during the vertical lifting process, avoid tilting that would cause the patient's center of gravity to shift, and ensure the accurate alignment of the imaging area.

[0035] refer to Figure 5 and Figure 6 As shown, the bottom of the lifting support plate 2 is symmetrically provided with sliding grooves 24 on both sides. The sliding grooves 24 are guide structures arranged laterally along the device, and their cross-section is "U" shaped, which is used to guide the sliding plate 41 to slide and move in them. The hole sealing mechanism 4 includes a sliding plate 41 that slides between the two sliding grooves 24. The sliding plate 41 is a rectangular structural plate, and its width is closely matched with the sliding grooves 24, so that the sliding is smooth. There is a space between the sliding plate 41 and the lower surface of the lifting support plate 2. This space is used to accommodate the sealing arc plate 43 and the spring return mechanism, so as to avoid the mechanism components being limited by the assembly height due to direct attachment.

[0036] refer to Figure 5 and Figure 6 As shown, two fixed cylinders 42 are symmetrically arranged on the lower surface of the slide plate 41. The fixed cylinders 42 are hollow cylinders that axially penetrate and accommodate the fixed rods 44. The fixed rods 44 are slidably passed through both fixed cylinders 42. The fixed rods 44 are vertically arranged and connected to the sealing arc plate 43 to form an up-down control device. The sealing arc plate 43 is arranged between the tops of the two fixed rods 44. The sealing arc plate 43 has a curved structure that matches the contour structure of the hollow hole 21, which can achieve tight coverage. The sealing arc plate 43 is placed in the space between the slide plate 41 and the lifting support plate 2, and can automatically reset through elastic force, ensuring that the sealing arc plate 43 can automatically spring up to cover the inspection hole when not in use, thereby improving the human-centered adaptability and privacy protection effect of the device.

[0037] refer to Figure 6As shown, a connecting crossbar 45 is provided between the bottoms of the two fixed rods 44. The connecting crossbar 45 is an integral pull member used to synchronously press down the two fixed rods 44. A spring 46 is sleeved on the surface of the fixed rod 44. The spring 46 is located inside the fixed cylinder 42. One end of the spring 46 abuts against the bottom of the fixed cylinder 42, and the other end abuts against the lower surface of the sealing arc plate 43. It is used to apply an upward elastic force to the sealing arc plate 43, so that it automatically fits the upper surface of the hollow hole 21. When performing a female breast examination, the connecting crossbar 45 is pulled to move the sealing arc plate 43 downward and separate it from the hollow hole 21 to avoid interfering with image acquisition. When the examination is completed or when performing a male examination, the crossbar 45 is released, and the spring 46 can drive the sealing arc plate 43 to move upward and automatically fit into the hollow hole 21, ensuring the shielding effect and preventing foreign objects from entering the imaging area.

[0038] The working principle of this utility model is as follows: The base plate 1 is fixed on the mobile bed of the magnetic resonance equipment. The patient lies face down on the lifting support plate 2. The lumbar support inclined plate 3 can support the waist, so that the breast is placed inside the hollow hole 21 to facilitate the detection of the breast. When in use, the height of the lifting support plate 2 can be adjusted to adapt to different detection environments. When adjusting, the knob 13 is rotated to control the rotation of the bidirectional screw 12 on one side. The belt transmission mechanism 16 enables the two bidirectional screws 12 to rotate synchronously. When the bidirectional screws 12 rotate, the two sliders 14 are controlled to move closer or further apart through different thread surfaces. At this time, the height of the lifting support plate 2 can be adjusted through the connecting rod 15 to improve practicality.

[0039] When examining breast cancer, the perforated hole 21 can be left open; conversely, when examining males, the perforated hole 21 can be closed. The slide plate 41 can slide along the surface of the slide groove 24. When the sealing arc plate 43 slides to a position corresponding to the perforated hole 21, the elastic force of the spring 46 can cause the sealing arc plate 43 to move upward and seal the perforated hole 21 to prevent embarrassment during male examination. The highest position of the spring 46 on the sealing arc plate 43 should ensure that the sealing arc plate 43 is flush with the upper surface of the perforated hole 21 after moving upward to prevent discomfort caused by protrusion or depression. When examining female breast cancer, the perforated hole 21 can be left open. The bottom connecting crossbar 45 can be pulled down to control the downward movement of the sealing arc plate 43 through the fixing rod 44. After the sealing arc plate 43 has completely moved downward and disengaged from the perforated hole 21, it can slide to one side to make the sealing arc plate 43 misaligned with the perforated hole 21.

[0040] Example 2

[0041] To further enhance comfort, a U-shaped headrest can be used. During testing, the headrest can be adjusted to accommodate different individuals by varying the distance between itself and the lifting support plate. Resting one's head on the U-shaped headrest provides greater comfort.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
