Powered Finger With Locking Rack Mechanism
US Patent:
2021036, Nov 25, 2021
Filed:
May 10, 2021
Appl. No.:
17/316357
Inventors:
- Olympia WA, US
Catherine Rocille Treadwell - Olympia WA, US
Catherine Rocille Treadwell - Olympia WA, US
International Classification:
A61F 2/58
A61F 2/70
A61F 2/70
Abstract:
This disclosure provides systems, apparatuses, and devices for a powered prosthetic digit. The disclosed devices restore prehension in a person with missing fingers or thumb by providing motor-driven extension and flexion, and opposition to forces in the extension direction via a pawl and locking rack ratchet mechanism, thereby allowing an individual to manipulate or stabilize objects. In one embodiment, a digit comprises a base configured to be removably couplable to an anchor, a first segment pivotably coupled to the base, and a second segment removably coupled to the first segment. The first segment comprises a rack with a plurality of rack teeth and a pawl with a nose configured to engage with the rack to prevent pivoting of the first segment in a rotational direction corresponding to extension of the prosthetic digit. The second segment comprises a drive gear operable to pivot the first segment with respect to the base.

Biomedical Finger Assembly With Ratcheting Lock
US Patent:
2021008, Mar 25, 2021
Filed:
Sep 22, 2020
Appl. No.:
17/028792
Inventors:
- Olympia WA, US
Catherine Rocille Treadwell - Olympia WA, US
Bradley Arthur Crittenden - Olympia WA, US
Catherine Rocille Treadwell - Olympia WA, US
Bradley Arthur Crittenden - Olympia WA, US
International Classification:
A61F 2/58
Abstract:
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.
