词条 | Iron hand (prosthesis) |
释义 |
Most iron hands are based on the same constructive principles, although there are considerable differences in complexity. Fingers can be flexed passively (for example using the healthy hand) and are locked in place by a ratchet mechanism, similar to those of contemporary flintlocks. Extension of the fingers works by spring pressure. Bibliography
