摘要： A hydraulic controller for the motion of a prosthetic joint has a piston--cylinder unit whose working chambers on opposite sides of the piston are connected to each other by a connecting passage and to a compensating chamber which stores a volume of hydraulic fluid to compensate for the difference in the volumes of the cylinder chambers resulting from the fact that the piston rod passes through one of them. Regardless of the direction of movement of the piston in the cylinder, utilizing checkvalves and adjustable throttle elements, the flow is controlled between the chambers so that separate throttle elements can effectively control the opposite movements while check valves permit filling of chambers.

摘要： 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 planet wheels of the two gearings engage a common gear between the sun and ring gear of one planetary gearing or the sun and ring gear of the other planetary gearing, the gearings being coaxial with one another and with the motors. A circuit responding to an increase in the current of the high speed motor above a threshold value is provided to control the switchover.

摘要： 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 generally traverses the articulation. The shaft and holder are then moved by the stump pivotally about the axis to establish extreme positions of the holder that cause discomfort to the patient. Movement within the extreme positions is established as an actual-value range and compared with a desired-value range. Then the fit of the shaft on the stump is adjusted and the first three steps are repeated until the actual-value range generally corresponds to the desired-value range. Normally the holder is pivotal about two generally perpendicular and coplanar holder axes and the intersection of the axes being set generally at the articulation.

摘要： 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 cylindrical wall. Since the lamellae are flexible, when there is a pressure increase in the chamber, the lamellae are deflected outwardly to reduce the free cross section of the throttle gap.

摘要： The invention relates to a hinge joint or swivel coupling in orthopaedic sthesis and ortheses, with an upper joint component (1), a lower joint component (2) and, if applicable, interposed control arms (9, 10) (hereinafter designated collectively as "hinge joint members") and a control element (4), that effectively engages both sides of a hinge joint member (1; 1, 2) (hereinafter "articulated joint member") each via one hinge point (7, 8) distanced from a pivot (3; 20, 21; 25, 26). To effect an improvement, the invention proposes that at least one of the above-mentioned hinge points (7, 8) is kinematically connected to at least one other hinge joint member (2; 9, 10; 9) via a mechanical geared coupling (11, 12, 13, 14; 15, 16, 17; 18, 24; 30, 31) and is arranged in such a way that it can change position in relation to its articulated joint member (1; 1, 2).

摘要： 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 other of two cylinder chambers upon displacement of the piston rod. The boot has a conically widening region or segment sealingly secured to the rod and adjoining the cylindrical segment of the boot surrounding the cylinder in a transition segment formed as an outwardly convex bulge and designed to ensure that initial inward movement of the piston rod will give rise to a plate membrane deformation of the elastic boot while only further displacement will result in a rolling action of the membrane. This ensures a generally cylindrical uniform configuration of the boot in all positions of the rod as is essential for effective use in a prosthesis.

摘要： 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 roller bearing is provided between outer peripheries of disk portions of these parts. A housing enclosing the parts contains a locking device in which a locking element is spring biased to engage the parts with teeth of the locking element engaging in teeth of the two parts. A push-button can be depressed to retract the locking element and permit relative rotation.
