Patent Number Title Of Patent Date Issued
5127420 Apparatus and method for fitting a prosthesis socket July 7, 1992
The service characteristics of a prosthesis shaft for a limb stump projecting from a pivotal articulation of a patient are determined by first fitting the shaft while engaged over the limb stump into a holder pivotal about a holder axis and then aligning the holder axis so that it ge
5046996 Planetary friction drive September 10, 1991
A planetary friction transmission, especially for miniature application as in prosthetic joints and the like, has cylindrical periphery planet wheels pressed by a stationary ring against a conical portion of the drive shaft, the ring being axially shiftable relative to the shaft and on a
5013326 Artificial hand May 7, 1991
An artificial hand has its finger gripper swingable about an axis which includes an angle of 30.degree. to 70.degree. with a plane normal to axis of a prosthesis connector and its fingers inclined at an acute angle to the finger carrier to provide a more natural orientation of the hand f
4923477 Prosthesis drive May 8, 1990
A prosthesis drive, especially for a hand prosthesis, can rapidly approach the grippers until resistance is sensed and then apply an increased force to the object. For this purpose, two electric motors drive selectively the respective planetary gearing in an arrangement in which the plan
4893648 Control valve January 16, 1990
A control valve for controlling the flow of a liquid, especially liquid of hydraulic damping unit with a hydraulic piston-and-cylinder arrangement, has a pressure chamber defined by lamellae extending along generatrices of a cylindrical housing wall and an end wall juxtaposed with this
4854428 Double-acting hydraulic piston-and-cylinder device August 8, 1989
A double-acting hydraulic piston-and-cylinder unit adapted to constitute a damper for movements in a human joint prosthesis has a boot sealingly connected to the cylinder and the piston rod to receive the hydraulic fluid under pressure as the hydraulic fluid is displaced from one or the
4795474 Rotary joint especially for a knee prosthesis January 3, 1989
A rotary joint, especially for a prosthesis, e.g. to allow a user to assume the lotus position, as a pair of relatively rotating parts including an outer part and an inner part braced at coaxial bosses by tapered rollers forming a play-eliminating tapered roller bearing. An inclined roll
4377305 Artificial hand March 22, 1983
This hand is provided with two clamping jaws (1,2) movable toward or respectively apart from each other, each of which is mounted in each case to a hinge quadrangle (3, 4). At each clamping jaw (1, 2) there is supported a gripping plate (8, 9) tiltable around an axis (5, 6) vertical
4186449 Swivel joint February 5, 1980
A swivel joint for a leg prosthesis has its relatively rotatable members urged into a neutral position by a multiple-disk compound axial compression spring bearing upon balls which ride along inclined ramps upon relative rotation of the members.
