[0031] The suspension assembly includes: an outer shell 410, a suspension cable 420, a drive motor 411, and a control panel 440. The outer shell 410 is fixedly connected to the crossbeam 310, a drum 413 is movably installed in the outer shell 410, and a suspension cable outlet is provided on the outer shell 410; one end of the suspension cable 420 is located outside the outer shell 410 and is fixedly connected to a limb fixing ring 421, and the other end of the suspension cable 420 extends into the outer shell 410 through the suspension cable outlet and is wound and fixed on the cylinder of the drum 413, and when the drum 413 rotates forward / reverse, the suspension cable 420 increases / decreases the length of the cable body rubbing against the cylinder of the drum 413 as the drum 413 rotates.

[0032] The driving motor 411 is installed in the outer shell 410, and its output shaft is coaxially connected to one end of the central axis of the reel 413 through a reducer 412, and the other end of the central axis of the reel 413 is installed on a bearing seat 414, and the bearing seat 414 is fixed to the inside of the outer shell 410.

In practice, the number of the suspension components can be further configured as 2 groups or 4 groups, and are symmetrically distributed on both sides of the crossbeam 310.

[0033] The working process of the above equipment is as follows:

[0034] First, the bed loaded with the patient is moved downward, and then the first motor 320 is started. Through the cooperation of the driving wheel and the driven wheel, the crossbeam 310 is moved to a suitable position along the track mechanism. Then, the first motor 320 is turned off, and the driving motor 411 is started. The driving motor 411 rotates forward, driving the reel 413 to rotate forward synchronously, so that one end of the suspension cable 420 moves vertically downward, and the limb fixing ring 421 moves to a position close to the patient's upper limb / lower limb. The staff turns off the driving motor 411 and fixes the patient's upper limb / lower limb to be suspended on the limb fixing ring 421. Then, the staff starts the driving motor 411 in the reverse direction, and the driving motor 411 drives the reel 413 to rotate in the direction, so that one end of the suspension cable 420 moves vertically upward, driving the patient's upper limb / lower limb into a suspended state. In this way, the patient's limbs are suspended and fixed during the operation.
