Description

Mammary tissue fixing device in mammary gland nuclear magnetic examination Technical Field The utility model relates to the technical field of medical equipment, in particular to a mammary tissue fixing device in mammary gland nuclear magnetic examination. Background In the field of medical diagnosis, breast magnetic resonance imaging (MR I) is widely used for early screening and diagnosis of breast diseases as an advanced medical imaging technique due to its characteristics of non-invasiveness, non-radiation and high resolution. However, in the actual examination process, due to physiological activities such as respiration and heartbeat of the subject and body position changes, motion artifacts often occur in the image, so that accuracy and reliability of diagnosis are affected. Based on the above problems, we provide a mammary tissue fixing device in mammary gland nuclear magnetic resonance examination. Disclosure of utility model In order to solve the technical problems that in the prior art, due to physiological activities such as respiration and heartbeat of a detected person and body position changes, motion artifacts often occur in images, and further accuracy and reliability of diagnosis are affected, the utility model provides a mammary gland tissue fixing device in mammary gland nuclear magnetic resonance examination. The utility model provides a mammary tissue fixing device in mammary gland nuclear magnetic examination, which adopts the following technical scheme: A mammary tissue fixing device in mammary gland nuclear magnetic resonance examination comprises a pair of throwing frames, a pair of shrinkage sleeves and an exhaust mechanism, wherein the two shrinkage sleeves are sequentially arranged in the corresponding throwing frames, the exhaust mechanism is communicated with the two shrinkage sleeves through a pipeline, and shaping particles are filled in the shrinkage sleeves. Preferably, the shaped particles are polystyrene particles. Preferably, the exhaust mechanism comprises a vertical cylinder communicated with the side end of the pipeline, a first partition plate is fixedly connected to the inside of the vertical cylinder, a movable rod is slidably connected to the top of the first partition plate, a first push pad is fixedly connected to the top end of the movable rod, a second push pad is fixedly connected to the bottom end of the movable rod, the second push pad is arranged below the first partition plate, an air bag is arranged at the top of the vertical cylinder through hose communication, a second partition plate is fixedly connected to the inside of the vertical cylinder at a position below the partition plate, a side opening of the pipeline is arranged below the second partition plate, exhaust holes are formed in the second partition plate and the second push pad, exhaust holes are formed in the position, between the first partition plate and the second push pad, of the outer side face of the vertical cylinder, and shielding assemblies are arranged on the second partition plate and the second push pad.
