ELBOW, 2-1/2 INCH SIZE WITH HALF CYCLE ALTERNATOR

Abstract

An elbow 2-1/2 in. size with half cycle alternator was designed and developed for use by very short above elbow, shoulder disarticulation and fore quarter amputees. The elbow provides the amputee with a means of positively locking the forearm with respect to the arm in 13 separate positions of flexion from the fully extended to the fully flexed position of approximately 5 degrees to 140 degrees. The locking mechanism can be engaged or disengaged with the same control motion. Flexion and operation of the terminal device is accomplished by energy transferred from the harness through a cable system to the elbow unit and terminal device. Forearm rotation is permitted between the top portion of the elbow unit and the turntable to which the upper arm shell is fastened. The amount of resistance to rotation is determined by the tension maintained to the attaching bolts.
