Prosthetic system consists from an excitation winding of the lifting unidirectional electromagnet (6), the pressure switch (5) and the battery (7), which are located in the body of the prosthesis (4). Orthopaedist directly during an operation (an amputation) pin down with screws to the bone stump (1) a ferromagnetic material (3), while the bone stump (1) is covered with conventional manner by a soft tissue (2). Pressure switch (5) disposed in the distal portion of the prosthesis (4) ensure switching on of the electric circuit of the excitation coil of the electromagnet (6), while proportionally of the size of the pressure bone stump (1) on the bottom of the prosthesis body the electrical current is increased in the coil of the electromagnet (6) and the generated electromagnetic field by means of ferromagnetic material (3) pressuring directly onto a bone stump (1). |
