Nuclear magnetic resonance auxiliary device for knee joint

Abstract

The invention discloses a nuclear magnetic resonance auxiliary device for a knee joint. The nuclear magnetic resonance auxiliary device for a knee joint effectively solves a problem that an imaging effect is affected due to the fact that a patient is prone to shaking during nuclear magnetic resonance of a knee joint. The nuclear magnetic resonance auxiliary device for a knee joint comprises a shell, a concentric-square-shaped plate is hinged into the shell through a rotating shaft, a guide plate is arranged on the concentric-square-shaped plate, a guide groove is formed in the guide plate, a sliding block is arranged in the shell, an insertion column is arranged on the sliding block, a first leg plate is hinged to an upper end of the concentric-square-shaped plate, a second leg plate is hinged to a right end of the first leg plate, the rotating shaft is sleeved with a T-shaped cylinder, an upper end of the T-shaped cylinder is hinged to the first leg plate, an H-shaped block is rotationally connected into the shell, and a cylindrical block is slidably connected into the shell through an ejector rod; and U-shaped rods are hinged to the first leg plate and the second leg plate, an arc-shaped plate is arranged at an upper end of each U-shaped rod, a pressing rod is slidably connected to the first leg plate and the second leg plate, respectively, a pressing plate is arranged at an upper end of each pressing rod, and the pressing rod is hinged to each U-shaped rod through a supporting rod. The device has an ingenious conception, is convenient to use, improves an imaging effect and also brings convenience to medical staff.

Description

technical field [0001] The invention relates to the technical field of radiology auxiliary equipment, in particular to a knee joint nuclear magnetic resonance auxiliary device. Background technique [0002] Nuclear magnetic resonance imaging is to use the principle of nuclear magnetic resonance, according to the different attenuation of the released energy in different structural environments inside the material, and through the detection of the emitted electromagnetic waves by an external gradient magnetic field, the position and type of the atomic nucleus that constitutes the object can be known. From this it is possible to draw a structural image of the interior of the object. When the knee has interlocking, effusion, instability, severe pain or limited mobility, and no obvious abnormalities are found on CT and X-ray films, consider ligament injury, synovial disease or meniscus The damage of these tissues does not develop on X-ray films and CT, and MRI examination is req...
