1. the structure is simple, and the supporting force provided to the forearms is not uniform;

2. uncomfortable to use for a long time;

3. the suspension mode is not beneficial to maintaining a good reduction state of the broken bone and rapid healing of the fracture;

4. the bracket type suspension device adopts a supporting plate made of composite materials to support the forearm, the elasticity and rigidity of the supporting plate are difficult to achieve the best matching effect, and the optimal rehabilitation effect cannot be achieved when the supporting plate is too hard or too soft;

5. once the existing suspension device for upper arm fracture is fixed, a patient can not adjust the suspension device with one hand;

6. the upper limbs keep a high posture for a long time in front of the chest, which is easy to cause fatigue and numbness, causes unsmooth blood circulation and is not beneficial to the rapid healing of broken bones;

7. the existing suspension device has no damping and buffering functions, so that pain is easily generated in daily life of a patient, and the healing of epiphysis is influenced;

8. most of the existing devices adopt an upper limb suspension device with a cloth belt wound around a neck brace, and the oppression on the neck and the cervical vertebra is inevitable;

9. the existing neck-winding belt mode is not suitable for patients with clavicle fracture, and the neck-winding belt mode can compress the clavicle to a certain extent and affect the healing of the clavicle;
