Device for controlling temperature of the implant and cement bone in cemented arthroplasty

摘要

This invenu00c7u00c3o relates to a device for temperature control of the implant bone cement and bone in its stage of polymerization.The device constituu00cddo termoelu00c9ctricas pads (1), operating under the effect of "Peltier", which are connected to the control unit (2) and a face of the wafer (1) in contact with the part (3), for its part, in contact with the bone implant (4), and if sensors of tempera Tura (5) connected to the control unit (2),It regulates the heat flows in termoelu00c9ctricas inserts (1) and the other face of the wafer (1) is in contact with heat sinks (6). A sensor of "Bragg" (9) is introduced into the bone cement (13) to measure the temperature and is connected to the control unit (2).This ensured the temperature control of the implant and bone cement at the stage of the polymerization, increasing the mechanical resistance of bone implant cement interface and reducing the effect of thermal necrosis in the bone.
