Abstract
A prosthetic finger can include a hub that attaches to a bone implant, a first phalange coupled to the hub, and a second phalange coupled to the first phalange. The first phalange can move in at least one of flexion or extension relative to the hub. The prosthetic finger can include a lever coupled to the first phalange. The lever can move between a first position and a second position. In the first position, the lever can prevent movement of the first phalange and the second phalange in extension. In the second position, the lever can allow movement of the first phalange and the second phalange in extension.
Claims20
A prosthetic finger comprising:
- a hub that attaches to a bone implant;
- a first phalange coupled to the hub, wherein the first phalange moves in at least one of flexion or extension relative to the hub;
- a second phalange coupled to the first phalange;
- and
- a lever coupled to the first phalange, wherein the lever moves between a first position and a second position, and wherein:
- in the first position, the lever is configured to prevent movement of the first phalange and the second phalange in extension;
- and
- in the second position, the lever is configured to allow movement of the first phalange and the second phalange in extension.
A prosthetic finger comprising:
- a first phalange, wherein the first phalange moves in at least one of flexion or extension;
- a second phalange coupled to the first phalange;
- a third phalange coupled to the second phalange;
- and
- a lever coupled to the first phalange, wherein the lever moves between a first position and a second position, and wherein:
- in the first position, the lever allows movement of the first phalange, the second phalange, and the third phalange in flexion;
- and
- in the second position, the lever allows movement of the first phalange, the second phalange, and the third phalange in extension.
A prosthetic finger comprising:
- a track that attaches to a bone implant;
- a first phalange coupled to the track, wherein the first phalange moves in at least one of flexion or extension along the track;
- a second phalange coupled to the first phalange;
- and
- a lever coupled to the first phalange, wherein the lever moves between a first position and a second position, and wherein:
- in the first position, the lever prevents movement of the first phalange and the second phalange in extension;
- and
- in the second position, the lever allows movement of the first phalange and the second phalange in extension.
