Abstract

Claims (14)

1. A prosthetic device, comprising:

a foot member comprising an end effector working element and one or more connecting members, the end effector working element comprising a ground-contacting bottom surface, wherein the end effector working element and the one or more connecting members are rigidly connected to one another, the foot member further including a first joint and a second joint, wherein the first joint and the second joint are located between a toe end and a heel end of the foot member;

a moveable body including a first joint and a second joint;

a base body directly coupled to the first joint of the foot member at a first location, the base body configured to couple to a residual limb of a user at a second location such that the base body is fixed or non-rotational with respect to the user;

a compliant linking member disposed between and connected to the second joint of the foot member and the first joint of the moveable body; and

an actuator disposed between and connected to the base body and the second joint of the moveable body,

wherein the foot member is configured to rotate as a single body relative to the moveable body.

2. The prosthetic device of claim 1 , further including a passive linking member coupled between a third joint of the foot member and a third joint of the moveable body.

3. The prosthetic device of claim 1 , wherein the compliant linking member includes a spring or flexible beam.

4. The prosthetic device of claim 1 , wherein the actuator includes a motor member, a moveable member, and a shaft between the motor member and the moveable member.

5. The prosthetic device of claim 1 , wherein the base body includes a shank and a housing configured to fit onto the residual limb of the user.

6. The prosthetic device of claim 1 , wherein the actuator is configured to output a linear motion in a direction along a height of the prosthetic device.

7. The prosthetic device of claim 1 , further comprising a prismatic joint member coupled between the base body and the moveable body, in parallel with the actuator.

8. The prosthetic device of claim 7 , wherein the prismatic joint member is a slidable linear bearing configured to reduce loading on the actuator.
