Wrist Joint for Prosthesis (v2)

grabcad

The "Wrist Joint for Prosthesis (v1)" is specifically designed to be a single assembly 3D print. However, this version can also be printed separately using an FDM printer. The ball and socket feature allows it to function as a swift disconnect system for attaching various terminal devices. The Socket (Yellow) has the capability to lock at 45 degrees in eight directions and at 90 degrees in four directions. Locking Pins (Red), either one or more, can be inserted into aligned holes to secure it further. Although a 3D printed Locking Pin is displayed, regular hardware can also be used as an alternative. By using two opposing pins, the ball joint can be transformed into a pivot joint. To demonstrate its versatility, a Pulley (Green) was attached to the Socket along with a quick-disconnect fitting and a 3D printed attachment (hair comb), which were previously submitted for the VA Innovation Creation Challenges under the title Quick Disconnect Interface (Snappy Tools).
