Prosthetic coupling device apparatus and method

A coupling device comprising:

• an internal mount including a proximate shaft portion and a distal mounting portion;
• a threaded sleeve formed around the distal mounting portion of the internal mount, the threaded sleeve including outer threads and secured to the internal mount via a fastening device to prevent the rotation of the threaded sleeve around the internal mount;
• a rotatable barrel formed around the proximate shaft portion and the distal mounting portion of the internal mount, the rotatable barrel including internal barrel threads that interface with the outer threads of the threaded sleeve;
• a detachable coupler formed to fit within the distal mounting portion of the internal mount, the detachable coupler including a coupler detent formed on a radially external surface of the detachable coupler wherein a distal end of the detachable coupler is couplable to a prosthetic foot via a pylon;
• a horizontal ball bearing shaft formed through the internal mount, the horizontal ball bearing shaft housing a ball bearing set wherein the ball bearing set interfaces with the coupler detent to lock the detachable coupler to the internal mount when the outer threads of the threaded sleeve are fully seated into the internal barrel threads;
• a retaining ring slot formed in an interior surface of the rotatable barrel;
• and a retaining ring formed into the retaining ring slot to prevent the rotatable barrel from being fully unscrewed from the internal mount and threaded sleeve.

A prosthetic coupling device comprising:

• an internal mount including a proximate shaft portion and a distal mounting portion, the proximal shaft portion couplable to a socket of a prosthetic device;
• a threaded sleeve formed around the distal mounting portion of the internal mount, the threaded sleeve including outer threads;
• a rotatable barrel formed around the proximate shaft portion and the distal mounting portion of the internal mount, the rotatable barrel including internal barrel threads that interface with the outer threads of the threaded sleeve;
• a detachable coupler formed to fit within the distal mounting portion of the internal mount, the detachable coupler including a coupler detent formed on a radially external surface of the detachable coupler, wherein a distal end of the detachable coupler is couplable to a prosthetic foot via a pylon;
• a horizontal ball bearing shaft formed through the internal mount, the horizontal ball bearing shaft housing a ball bearing set wherein the ball bearing set interfaces with the coupler detent to lock the detachable coupler to the internal mount when the outer threads of the threaded sleeve are fully seated into the internal barrel threads;
• a retaining ring slot formed in an interior surface of the rotatable barrel;
• a retaining ring formed into the retaining ring slot to prevent the rotatable barrel from being fully unscrewed from the internal mount and threaded sleeve;
• and a spring and ball channel formed vertically into a top surface of the threaded sleeve to house a spring and tactile ball bearing.
