Method for measuring the displacement of bone fragments treated with external fixation and a device for measuring the relative displacement of the bone fragments treated with external fixation

摘要

how to measure movements of bone treated with external stabilizer is characterized by the fact that one fastened to the stabilizer and to external offshoot of marrow bone nut (15) essentially perpendicular to its length between zewnu0119trzn stabilizer um,a splinter bone zamocowuje is tangentially napru0119u017conu0105 to wkru0119tu marrow (15) przesuwnu0105 axial needle measuring (7) zu0142u0105czonu0105 with the second cover (1b) of the aircraft (1), which capacitor flat first, parallel and naprzeciwlegu0142a to the other cover (la) is affixed to the stabilisation lizatora externalis then measured in the unladen condition a stabilised bone volume air capacitor flat (1), then is stabilized bone and re measured aircraft capacity capacitor flat (1) in the load condition.on the basis of the change of the aircraft (1) flat capacitor is calculated distance displacement wkru0119tu marrow (15) at a measuring needle (7),and then considering the relationship of wkru0119tu marrow (7) between a splinter bone and needle measuring (7) during the test and measurement between the needle (7) and the place attachment wkru0119tu marrow (15) in stabilizatorze outside on the basis talesa is calculated from legu0142ou015bu0107 movement of marrow.device for measuring the relative movements of bone treated with external stabilizer is characterized by the fact that the aircraft is built with flat capacitor (1), whose first cover (la), naprzeciwlegle and parallel to the other, is affixed to the rami in the first (2) mounted to a slider (3a) displacement mechanism (3) located in a body (4),a second cover (1b) placed on suwaku (6), ending after naprzeciwlegu0142ej side needle measuring (7) and mounted on the second arm (5) fastened to the body (4), with the mounted arm (5) second zipper (6) napru0119u017cony is a spring element (8) in the direction rozwieraju0105c a flat capacitor covers aircraft (1).
