MAGNETIC DETACHABLE NEGATIVE Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: device has electric coil with core as magnetic field source and two half-negatives each being produced from magnetizable molding material having working cavity, two horizontal polar plates of both negatives, one of pairs of plates of the same polarity being provided with slots for anatomic object to pass through. Both half-negatives plates of the same polarity are hingedly connected to each other and to the core of the electric coil near one of end faces. Detachable negative has headpieces for modeling required members of an anatomical object, and borders for molding material. The modeling headpieces are provided with protrusions and recesses are produced from non-ferromagnetic material, ferromagnetic material or their combination. The borders of each of negative halves optionally have modeling units for fixing modeling headpieces in negative. Semiannular ferromagnetic inserts are placed in the slot for anatomic object to pass through. Thin non-ferromagnetic separating plates are to be placed along the plug of one of negative halves. Modeling headpieces are in the area of the kneepan proper ligaments and at the level of knee joint slit and popliteal fossa for producing crus negative. EFFECT: facilitated process of polar plates production; low labor costs; wide range of technological application. 7 cl, 5 dwg
