Technical Field

[0001] The utility model relates to the field of breast nuclear magnetic resonance, in particular to an adjustable limb auxiliary bracket. Background Art

[0002] Breast MRI is a new medical imaging technology that uses the principle of nuclear magnetic resonance to image breast tissue. Compared with traditional mammography and ultrasound examinations, breast MRI has higher sensitivity and resolution, and can more accurately assess the nature of the lesions and determine the extent of the lesions. After breast surgery, the arms cannot move and an auxiliary bracket needs to be installed for rehabilitation activities.

[0003] Most of the existing auxiliary brackets require patients to move independently, and patients cannot control the range of movement, which may cause secondary injuries. Some auxiliary brackets are electrically controlled but cannot control the angle of movement, which may also cause patients to over-move. Therefore, those skilled in the art have provided an adjustable limb auxiliary bracket to solve the problems raised in the above background technology. Utility Model Content
