Publication number: 20230320873Abstract: This disclosure provides systems, apparatuses, and devices for a prosthetic digit usable with persons with amputations at or proximal to the metacarpophalangeal joint. The device restores prehension in a person with missing fingers or thumb by providing opposition to forces in the extension direction via a spring-loaded pawl and locking rack ratchet mechanism, thereby allowing an individual to manipulate or stabilize objects. The digit may be spring-loaded in the extension direction by a torsion spring or other biasing member. The pawl may be automatically disengaged from the rack when the digit reaches full flexion, and the full flexion disengage stop may be adjustable. The pawl may be automatically engaged with the rack when the digit reaches full extension, and the extension stop may be adjustable. The pawl may contain a lateral feature that creates interference with the anchoring linkage under load and limits deflection of the structure.Type: ApplicationFiled: December 9, 2022Publication date: October 12, 2023Inventors: Erich Theodore Griebling, Catherine Rocille Treadwell, Bradley Arthur Crittenden

Publication number: 20230263645Abstract: The disclosure provides apparatus and methods of use pertaining to a biomechanical finger brace assembly. In one embodiment, the assembly includes a coupling tip, a proximal ring configured to concentrically receive a user's finger, a distal ring configured to concentrically receive the finger, and a rocker formed in an H-shape. The distal ring and the rocker are pivotally suspended between a proximal coordinated pivot point anchored on the proximal ring and a distal coordinated pivot point anchored on the coupling tip, such that movements of the finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. The coupling tip may include an open end or an enclosed recess to accept a minimally-amputated or non-amputated finger. Other embodiments are also disclosed.Type: ApplicationFiled: February 3, 2023Publication date: August 24, 2023Inventors: Robert Thompson, JR., Jon Bengtsson, Anthony Charles Peto, Charles Colin Macduff, Sydney Tye Minnis, Eric Dennis Klumper, Bradley Arthur Crittenden

Publication number: 20220378586Abstract: The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. In one embodiment, the assembly includes an eccentric metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A ring configured to receive a user's residual finger is disposed upon the articulation assembly, and may be adjusted to a target location based on a length of the residual finger. The articulation assembly is configured to utilize vertical movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-z plane, and the MCP pivot is configured to utilize lateral movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-y plane. Other embodiments are also disclosed.Type: ApplicationFiled: August 8, 2022Publication date: December 1, 2022Inventors: Robert Thomspon, JR., Jon Bengtsson, Anthony Charles Peto, Sydney Tye Minnis, Eric Dennis Klumper, Bradley Arthur Crittenden

Publication number: 20220313456Abstract: A prosthetic digit usable with capacitive panels is provided. The digit includes at least one conductive layer surrounding the body of the digit, and a non-conductive sealing layer around the conductive layer preventing direct external contact of the conductive layer with the capacitive panel. The digit may have a conductive tip pad to create a series capacitive pathway between the conductive layer of the body and the electrodes of the capacitive panel. Using the digit with a capacitive panel does not require a direct conductive pathway, e.g., a pathway between the capacitive panel and the structure of the device, the user's skin, or metallic sink.Type: ApplicationFiled: April 2, 2021Publication date: October 6, 2022Inventors: Ana Rosa Acevedo, Bradley Arthur Crittenden, Erich Theodore Griebling, Rachel Adsit Lowing, Liam Aloysha Mooney, Catherine Rocille Treadwell

Publication number: 20220054283Abstract: The disclosure provides apparatus and methods of use pertaining to a prosthetic finger assembly. In one embodiment, the assembly includes a coupling tip and a distal ring coupled with the coupling tip. The assembly further includes a proximal ring coupled with the distal ring. A rocker formed in a Y-shape with a first end forming a single prong and a second end forming a split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and Y-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring and the distal articulate the distal ring together with the rocker to curl and bend the coupling tip. Other embodiments are also disclosed.Type: ApplicationFiled: November 5, 2021Publication date: February 24, 2022Inventors: Robert Thompson, JR., Jon Bengtsson, Anthony Charles Peto, Charles Colin Macduff, Sydney Tye Minnis, Eric Dennis Klumper, Bradley Arthur Crittenden
