ARTIFICIELL HANDLED FOR EN ARMPROTES MED ETT PROTESFESTE OCH EN MED DETTA FORBUNDEN KONSTGJORD HAND, EVENTUELLT UTFORMAD SOM ETT ARBETSREDSKAP

摘要

The artificial wrist serves to connect an arm prosthesis shaft to an implement and comprises distal retaining means, a proximal retaining member adapted to extend into said prosthesis shaft and formed with first and second engaging surfaces, locking means interlocking with said distal retaining means and said first engaging surface to hold said distal retaining means and said proximal retaining member axially together, a sliding surface bearing adapted to rotatably connect an implement to said distal retaining means, and rotatable coupling means which engage said second engaging surface and are adapted to engage said prothesis shaft.
