【Abstract】 Objective To design a set of implanted electric artificial intelligent metacarpophalangeal joint and investigate a new strategy for the reconstruction of hand function after brachial plexus injuries. Methods The implanted electric artificial intelligent metacarpophalangeal joint was made of implanted materials and designed with the methods combined medicine with technology. The major function was checked with the demonstration of corpse. Its activity and practicability was observed. Results The design of the implanted electric artificial intelligent metacarpophalangeal joint was completed successfully. The demonstration of corpse revealed that the design was rational and fixed easily in the operation. The range of activity of the artificial metacarpophalangeal joint was between 90 degree of flexion and 0 degree of extension. The major function was comparable with the requirement of artificial articulation. Conclusion The implanted electric artificial intelligent metacarpophalangeal joint provides a new and hopeful strategy for the reconstruction of hand function after brachial plexus injuries.更多还原
