Title: Innovations by John W. Stephenson
Introduction
John W. Stephenson is an accomplished inventor based in Dallas, TX (US). He has made significant contributions to the field of prosthetics, particularly in developing devices that assist upper extremity amputees. With a total of 2 patents, his work focuses on enhancing the quality of life for individuals with disabilities.
Latest Patents
Stephenson's latest patents include a swing regulating mechanism and a wrist emulator designed to assist amputees in swinging a golf club. The golf prosthesis he developed comprises first and second prosthetic sockets that accommodate the amputee's limbs. An extension pylon extends from the first socket towards the golf club, ensuring that the amputee maintains proper alignment of the shoulders, back, and hips during the swing. This design allows for a more complete transfer of energy from the body into the swing.
The wrist terminal device connects the extension pylon to the golf club, emulating the natural cocking and release of the wrists during a conventional golf swing. It features a club holder that firmly grips the golf club and a rotary joint that is restrained from rotation except in a preselected plane. This plane can be adjusted based on the direction the amputee wishes to hit the ball. The rotary joint allows for controlled rotation during the swing, and in some embodiments, spring action encourages the device to return to a rest position, ensuring the golf club is properly aligned when the amputee addresses the ball.
