FIELD: medical engineering; prosthetics and prosthesis engineering. SUBSTANCE: hand prosthesis comprises framework of palm coupled with wrist imitator with rotator and with 1st finger with the help of flat articulation joints. These flat joints can be flexible from both sides with the help of locking/unlocking pushbuttons located at convenient points.
