摘要：
A prosthetic device having a proximal interphalangeal joint (PIP) and a metacarpophalangeal joint (MCP), comprising a first prosthetic digit comprising one or more first phalanges and a four-bar linkage to operatively couple the PIP joint to the MCP joint, a first engagement portion positioned on one of the first phalanges, the first engagement portion comprising a locking linkage extending along the phalange, the locking linkage being part of the four-bar linkage, and a first stopping portion comprising a stopping element configured to be positioned above the locking linkage, wherein the locking linkage is capable of engaging with the stopping element by passing the one of the first phalanges in which the locking linkage is positioned through a mechanical singularity to lock the first prosthetic digit such that each of the one or more phalanges is in a position of flexion in response to a force applied to the first prosthetic digit.
