Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and more specifically, to a breast tissue fixation device in breast MRI examination. Background Technology

[0002] In the field of medical diagnostics, breast magnetic resonance imaging (MRI), as an advanced medical imaging technology, is widely used for the early screening and diagnosis of breast diseases due to its non-invasive, radiation-free, and high-resolution characteristics. However, during actual examinations, physiological activities such as breathing and heartbeat, as well as changes in body position, often lead to motion artifacts in the images, thus affecting the accuracy and reliability of the diagnosis.

[0003] To address the aforementioned issues, we provide a breast tissue fixation device for breast MRI examination. Utility Model Content

[0004] To address the technical problem mentioned in the background art, where motion artifacts often appear in images due to physiological activities such as breathing and heartbeat, as well as changes in body position during actual examinations, thus affecting the accuracy and reliability of diagnosis, this utility model provides a breast tissue fixation device for breast MRI examination.

[0005] The present invention provides a breast tissue fixation device for breast MRI examination, which adopts the following technical solution:

[0006] A breast tissue fixation device for breast MRI examination includes a pair of delivery frames, a pair of contraction sleeves, and an air venting mechanism; the two contraction sleeves are sequentially arranged in the corresponding delivery frames; the air venting mechanism is connected to the two contraction sleeves through a pipeline; the interior of the contraction sleeves is filled with shaping particles.

[0007] Preferably, the shaped particles are polystyrene particles.

[0008] Preferably, the exhaust mechanism includes a vertical cylinder connected to the side end of the pipeline. A partition plate is fixedly connected inside the vertical cylinder. A movable rod is slidably connected to the top of the partition plate. A push pad is fixedly connected to the top of the movable rod, and a push pad is fixedly connected to the bottom of the movable rod. The push pad is arranged below the partition plate. An airbag is connected to the top of the vertical cylinder via a flexible hose. A partition plate is fixedly connected inside the vertical cylinder below the partition plate. The side opening of the pipeline is arranged below the partition plate. Exhaust holes are provided on both the partition plate and the push pad. An exhaust hole is provided on the outer side of the vertical cylinder between the partition plate and the push pad. Shielding components are provided on both the partition plate and the push pad.

[0009] Preferably, the shielding assembly includes a plurality of limiting rods fixedly connected to the top of the second partition, and a shielding ring is slidably sleeved between each of the limiting rods.

[0010] Preferably, the airbag cavity is larger than the cavity on the partition.

[0011] Preferably, the shrink sleeve is made of TPU material.

[0012] In summary, this utility model has the following beneficial technical effects:

[0013] 1. By placing two delivery frames sequentially in the grooves of the MRI machine's prone position (for breast examination), the patient lies prone, allowing the breast tissue to hang naturally under gravity and be placed within the contractile sleeve. The loose contractile sleeve adheres to the breast tissue. Then, the sleeve is vented and contracted through an air venting mechanism, allowing it to contract and conform to the breast tissue. The shaping particles within the sleeve, under the action of the sleeve, form a stable outline of the breast tissue. Magnetic resonance imaging (MRI) of the breast tissue is then performed. This structural design enables the stable acquisition of complete breast MRI images, which helps reduce the interference of artifacts caused by movement during the examination on the diagnostic results.

[0014] 2. At the same time, all materials used are non-magnetic, ensuring compatibility with the magnetic resonance imaging environment and not affecting the imaging quality of the magnetic resonance imaging.

[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0025] It should be noted that the accompanying drawings are schematic and not to scale.

[0026] Example 1

[0027] This utility model discloses a breast tissue fixation device for breast MRI examination. (Refer to...) Figures 1 to 4 A breast tissue fixation device for breast MRI examination includes a pair of delivery frames 1, a pair of contraction sleeves 2, and an exhaust mechanism 3; the two contraction sleeves 2 are sequentially arranged in the corresponding delivery frames 1; the exhaust mechanism 3 is connected to the two contraction sleeves 2 through a pipeline 4; the interior of the contraction sleeves 2 is filled with shaping particles 5.

[0028] Specifically, two placement frames 1 are placed sequentially in the grooves of the MRI machine's breast examination bed (for breast tissue examination). The patient then lies prone, allowing the breast tissue to hang naturally under gravity and be placed within the contraction sleeve 2. The loose contraction sleeve 2 adheres to the breast tissue. The contraction sleeve 2 is then vented and contracted by the exhaust mechanism 3, allowing it to shrink and conform to the breast tissue. The shaping particles 5 within the contraction sleeve 2, under its influence, form a stable outline of the breast tissue. MRI examination of the breast tissue is then performed. This structural design ensures stable and complete breast MRI images, helping to reduce artifacts caused by motion during the examination. Furthermore, all materials used are non-magnetic, ensuring compatibility with the MRI examination environment and preventing any impact on the quality of the MRI imaging.

[0029] Specifically, shaping particle 5 is polystyrene particle.

[0030] like Figure 4 As shown, the exhaust mechanism 3 includes a vertical cylinder 300 connected to the side end of the pipeline 4. A partition 301 is fixedly connected inside the vertical cylinder 300. A movable rod 302 is slidably connected to the top of the partition 301. A push pad 303 is fixedly connected to the top of the movable rod 302, and a push pad 304 is fixedly connected to the bottom of the movable rod 302. The push pad 304 is located below the partition 301. An airbag 305 is connected to the top of the vertical cylinder 300 via a flexible hose. Inside the vertical cylinder 300, located below the partition 301... A partition plate 2 306 is fixedly connected to the position. The side opening of the pipeline 4 is arranged below the partition plate 2 306. Both the partition plate 2 306 and the push pad 2 304 are provided with exhaust holes. The outer side of the vertical cylinder 300 is provided with exhaust holes at the position between the partition plate 1 301 and the push pad 2 304. Both the partition plate 2 306 and the push pad 2 304 are provided with shielding components. The shielding components include multiple limiting rods 307 fixedly connected to the top of the partition plate 2 306. A shielding ring 308 is slidably sleeved between each limiting rod 307.

[0031] The exhaust mechanism 3 is used by pressing the airbag 305, which causes the gas inside the airbag 305 to enter the upper cavity of the partition 301. This pushes the push pad 303 downward (the air below the push pad 303 is compressed). The downward movement of the push pad 303 causes the moving rod 302 to move the push pad 304 downward. At this time, the air below the push pad 304 will push the push pad 304 upward through the exhaust hole on the push pad 304 and be discharged through the exhaust hole on the vertical cylinder 300. Releasing the lever... When the airbag 305 is in operation, the compressed air will be restored, causing the push pad 303 to move upward, which in turn drives the push pad 304 to move upward. When the push pad 304 moves upward, the shielding ring 308 on the push pad 304 will shield the exhaust hole on the push pad 304. Under the action of negative pressure, the shielding ring 308 on the partition 2 306 will be lifted, so that the air in the shrink sleeve 2 will enter the lower part of the push pad 304. This process is repeated to release the air in the shrink sleeve 2 and complete the shrink sleeve 2.

[0032] Specifically, the cavity of airbag 305 is larger than the cavity on partition 301. This design ensures the movement of the two push pads.

[0033] Specifically, the shrink sleeve 2 is made of TPU material.

[0034] It is worth noting that: Figure 7 As shown, the two shrink sleeves 2 can also be designed as a single piece to accommodate different patients.

[0037] Specifically, shaping particle 5 is polystyrene particle.

[0038] like Figure 5 and Figure 6 As shown, the exhaust mechanism 3 includes a detachable air pump 6 installed on the side of the pipeline 4, and a manual valve 7 is also installed inside the pipeline 4.

[0039] Specifically, by connecting the air pump 6 to the side end of the pipeline 4, the shrink sleeve 2 is shrunk by the air pump 6. Through this structural design, the air exhaust and shrinkage of the shrink sleeve 2 can be completed quickly.
