Prosthetic wrist

Abstract

The invention relates to a prosthetic wrist having a base for fastening to a proximal prosthesis component and having a pivot part which is mounted on the base in such a way as to be pivotable about a pivot axis,—having at least one fastening device for securing a distal prosthesis component or prosthetic hand to the pivot part, wherein—at least one catch segment with form-fit elements arranged thereon is arranged on the pivot part, and—at least one locking element is mounted on the base in such a way as to be longitudinally displaceable along the pivot axis, which locking element can be brought from a locking position, in which the locking element is in engagement with a form-fit element of the catch segment, counter to a spring force into a release position, wherein the locking element has two release regions with which a first and a second release position are realized, the first release region being arranged spaced apart from the second release region in the direction of displacement, and the second release region being assigned a catch element which holds the locking element in the second release position.
