Further: the number of the tensioning ropes 1 is two, and the two tensioning ropes 1 are symmetrically distributed.
The beneficial effects of the further scheme are as follows: the balance of the whole device can be ensured by arranging a plurality of pull ropes.
Further: the body chain 2 and the locking component 3 are both absorbable magnesium alloy, and the tensioning rope 1 is an absorbable wire.
The beneficial effects of the further scheme are as follows: this arrangement allows the device as a whole to be absorbed.
Further: one end of the locking screw 32, which is in contact with the inner side of the C-shaped clamping block 31, is in a grinding shape and is provided with absorbable cotton.
The beneficial effects of the further scheme are as follows: the locking bolt arranged in this way can prevent the discomfort of the patient caused by over-compression on the ribs.
