METHOD OF metal screws for osteosynthesis AND DEVICE FOR ITS IMPLEMENTATION

摘要

1.Sposob of metal screws through the bone for osteosynthesis according to which access the damaged bone, the comparison of the bone fragments (repositioning) the temporary fixation Bone holding forceps fracture splinting damage zone plate with holes through which the channels are formed with threaded walls for the screws that fix the plate to the surface, characterized in that the threading is carried out while controlling the torque and depth of thread cutting with limited depth of at an equal reduction in the torque to a value of 0.7-0.8 and the maximum current output visual information for the doctor, and the introduction of the screws operate to control the torque and the screwing depth, limiting the torque at the final stage of the maximum level of 0.8-1.2 when narezanii.2. An apparatus for metal screws for fixation through bone, comprising: a DC geared motor with a collet chuck with exchangeable tools on the output shaft, the block motor reducer control, characterized in that it further comprises a torque sensor rotation output shaft of the geared motor, a sensor the number of revolutions of the output shaft of the geared motor unit job parameters, a microprocessor data transfer apparatus and two comparison unit, wherein the torque sensor and outputs rotation speed you a shaft geared motor connected to the data inputs of the microprocessor unit and the first inputs of the first and second comparison unit, respectively, second inputs of which are connected to first and second outputs parameter setting unit
