Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a breast support for radiological examination. Background Technology

[0002] Breast cancer is one of the most common cancers among women, and early detection is crucial for improving cure rates. With advancements in medical imaging technology, mammography has become one of the effective methods for early detection of breast cancer. However, precise control of the breast position is critical for obtaining the clearest images. Therefore, breast supports are designed to optimize this process, improving image quality by providing stable support while minimizing patient discomfort.

[0003] Chinese utility model patent CN212651240U discloses a breast support for radiotherapy, including a supine bed with a head recess and two chest recesses. Two hand positioning rods are located at the end of the bed near the head recess, closer to the end of the bed than the head recess. The bed has a sliding track for the hand positioning rods to move, with the two hand positioning rods moving synchronously in the same direction relative to the center point of the sliding track. This breast support improves the accuracy and effectiveness of radiotherapy by fixing the patient's hand position and reducing body distortion. However, it still has shortcomings in practical applications. Because it only supports radiotherapy in three basic lying positions (supine, prone, or lateral), certain treatment needs may require other more complex positions, such as a semi-sitting position or a position with a large tilt angle. The current design may not fully meet these special needs, limiting its application. Utility Model Content

The hydraulic cylinders 4 are used to drive the mounting plate 3 to rotate and adjust the examination angle. A groove is provided in the center of the mounting plate 3, and a slider 5 is slidably installed in the groove. A seat frame 7 is fixedly installed in front of the slider 5, providing a seat for the patient to sit and undergo examination. A motor 9 is fixedly installed on the upper part of the rear side of the mounting plate 3, and a lead screw is fixedly connected to the output shaft of the motor 9. 8. The lead screw 8 and the slider 5 are threaded together. Sliding frames 10 are symmetrically slidably installed on the upper left and right sides of the front support plate surface of the mounting plate 3. Each sliding frame 10 is hinged with a hinge plate 12. The hinge plate 12 is used to support the patient's arms. Arm straps 121 are provided on the opposite side of the two hinge plates 12. The patient sits on the seat frame 7 and leans against the mounting plate 3. The motor 9 drives the slider 5 and the seat frame 7 to rise and fall through the lead screw 8, so that the examination area of ​​patients of different heights can be raised and lowered to a suitable examination height. The patient brings their arms close to the hinge plate 12 and the arm straps 121 are used to stably bind the patient's arms to the hinge plate 12. Finally, the hydraulic cylinder 4 drives the support angle of the mounting plate 3 to change. The patient leaning against the mounting plate 3 can flexibly adjust the examination angle, so that this bracket can meet the examination needs of different patients' breasts.

[0022] like Figure 3 and Figure 4As shown, two electric push rods 11 are symmetrically fixedly installed on the upper part of the mounting plate 3. The push rod of the electric push rod 11 is connected to the sliding frame 10 on the same side. The electric push rod 11 is used to drive the hinge plate 12 on the sliding frame 10 to stably adjust the distance of the support arm. A second motor 14 is fixedly installed at the bottom of the sliding frame 10. The output shaft of the second motor 14 is connected to the rotating shaft of the hinge plate 12. The second motor 14 is used to drive the hinge plate 12 to rotate, thereby changing the angle of the support arm and improving the stability and comfort of the patient's arm.

[0023] like Figure 2 and Figure 4 As shown, an accordion baffle 6 is installed on the slide groove of the mounting plate 3.

A pillow 15 is fitted onto the top front side of the mounting plate 3. The pillow 15 is used to provide support for the patient's head, so that the patient's head can rest on the pillow 15 when the mounting plate 3 is tilted during the examination, thereby improving the patient's comfort during the radiological examination.

[0026] When using this support frame to assist patients in breast radiography examinations, the patient sits on the seat frame 7 with their back against the mounting plate 3. The drive motor 9 rotates the drive coil, allowing the slider 5 to move up and down along the groove, thereby adjusting the height of the seat frame 7 to accommodate patients of different heights. This ensures that the thymus examination site for each patient is accurately positioned at the ideal examination height. Simultaneously, to ensure proper and stable support for the patient's arms, both arms are placed on the side hinge plates 12 and corresponding extension plates 13. Depending on the actual length of the patient's arms, they are secured using arm straps 121. The hinge plates 12 used to secure the arms can be adjusted not only by the electric push rod 11 to adjust the support distance but also by the drive motor 14 to rotate and adjust the angle. This design caters to different body types and postures, providing optimal support and comfort, thereby improving the quality of radiographic images. Furthermore, the extension plates 13 at the front of the sliding frames 10 on both sides offer additional adjustment flexibility, ensuring that even slight movement of the patient's arm does not affect overall support, guaranteeing the arm remains in the correct examination position. Finally, before the specific radiographic examination, medical personnel can adjust the angle of the mounting plate 3 according to the examination needs. By activating the hydraulic cylinder 4, the mounting plate 3 is driven to rotate around the hinge axis 2, adjusting to the most suitable angle for imaging. During the examination, the lead neck brace 16 on the mounting plate 3 protects the neck from radiation, while the headrest 15 provides comfortable support for the head, further enhancing the safety of the examination and the patient's comfort.
