COMBINED ADJUSTING DEVICE FOR LOWER LIMB PROSTHESIS Russian patent published in 1999 - IPC

FIELD: prosthetics engineering. SUBSTANCE: device is used in prostheses of crus and thigh after exatriculation of high. It provides for linear and angular adjustment operations in frontal and sagittal planes independently from each other. It also ensures rotary motions of distal and proximal sections of prosthesis with respect to each other and correction of prosthesis length in process of experimental wearing. Device has two adapters. One of them contains through pairs and spherical recess at end face, and the other has spherical projection and tapered round holes from one of its sides. Four bolts pass through recesses and holes. One of adapters is provided with rectangular holes and the other, with round ones. Bolts passing through these holes have two nuts and one spherical washer each. EFFECT: enhanced efficiency. 2 dwg
