Disease analysis: some fingers are missing and have thumbs, while the other four fingers have more than one finger. People who still master the functions of thumb and relative fingers can wear silicone rubber simulated fingers or gloves to solve the aesthetic problem, which is very beautiful. Suggestion: As long as there is more than one movable finger, a silicone rubber artificial hand with skeleton can be specially designed and customized for science students to make up for the missing part, and things can be taken by the movement of real fingers.
