The structure for an artificial limb includes a domed element and a hollow cylindrical coupling defining a beveled outer surface at one end thereof. The hollow cylindrical coupling is positionable within the beveled outer surface adjacent the domed element to form a bondable joint therebetween.

An elastomeric sleeve, for retaining and attaching a prosthesis to a stump of an amputee. Typically, the sleeve is made of polyurethane, soft elastomer reinforced with a nylon or polyurethane mesh. This reinforcement, among other things, eliminates the possibility of support failure caused by a small tear or cut. The polyurethane elastomer is selected to have a resilience, load bearing capability and energy and impact absorption similar or close to that of the enclosed limb adjacent to the sleev...

A brace or limb protector, which in hinging, matches the complex bending motion of the natural knee of a human being. The hinge mechanism has supports for the upper and lower leg which are attached to each other by a hinging mechanism which is connected to and pivots on the support at a first position (50) and a second position (72) respectively. Connection of the supports at the first position (50) is to the plate of the hinge mechanism and at the second position (72) to the arm which pivots on...

A bow includes a riser and a pair of limbs attached to the support member and riser with a reed assembly including a string strip. The limbs are attached to rear of the riser. The bow may also include a string guide attached to the support member or support portion of the riser.

The present invention provides an articular endoskeletal prosthesis 1 for providing a user with at least one of a mechanically operable pivoting wrist, elbow and shoulder joint. The prosthesis 1 has at least one elongate endoskeletal tube upper limb member 5 with a proximal end portion 6 having a pivotal connection 7 to a support body 9 therefor. One of said upper limb member proximal end portion 6 and said support body 9 has a fixed worm gear wheel means 19 and the other a drive motor 22 having...

The present invention includes a band for a person's limb or digit. The band has a body portion, at least one first strap portion extending in cantilever fashion from one side of the body portion toward another side of the body portion and at least one second strap portion extending in cantilever fashion from the another side of the body portion toward the one side of the body portion. The body and strap portions define an opening for receiving a limb or digit. The first and second strap portion...

A six degree of freedom limb movement resistance system is described in which a linkage system of links and joints couples a fixed point in space to a movable end-point of the linkage. A limb coupling cuff is attached to the end point. Variable resistance force can be applied to the linkage via computer controls through a feedback path from position and velocity sensors. The linkage endpoint force acting to resist limb motion is in a direction opposite to the endpoint velocity vector.

A lower limb prosthesis as a prosthetic foot and an elongate rod formed substantially of unidirectional long fibers embedded in a thermoplastic matrix, the fibers extending substantially parallel to the length of the rod. An adjustment apparatus for the prosthesis includes a pair of pods which may be clamped to the rod and rotated at controlled angles once the thermoplastic rod has been heated to its deformation temperature.

This invention is a flexible limb capable of changing length, bending in any direction, twisting, and changing cross-sectional size. Its skeletal structural design promotes optimal simplicity of control, ease of construction, lightness, and stiffness.

A prosthetic limb (10) for a below-the-elbow amputee is constructed having a removable effector (16) removably mounted in a mount (18) having semicircular bands (20) set by "hand lapped" construction in sides of a body (12) near a closed end (22) thereof. The effector (16) is offset from the body (12) and is provided with supports (60, 62), each having a C-shaped slot (64, 66) for receiving a horizontally oriented bar, such as that on a chainsaw. A pair of semi-circular gripping members (68, 70)...
