[0018] 2. In this invention, by driving the swing plate in the lifting mechanism to move up and down repeatedly, the swing plate causes the patient's arm and hand to move up and down synchronously, thereby accelerating the blood return of the patient's arm, preventing ischemia and hypoxia at the surgical site, and thus improving the recovery effect and recovery speed of flap or finger replantation surgery.

[0019] 3. In this invention, the sponge sleeve in the massage mechanism rotates slowly. As the patient's hand is raised, the back of the hand comes into contact with the sponge sleeve. The rotation of the sponge sleeve massages the back of the patient's hand, thereby ensuring blood circulation in the patient's hand and further improving the recovery effect and speed of flap or finger replantation surgery.
