INSTRUMENT HAVING ROTATION DEVICE Russian patent published in 2004 - IPC

FIELD: medical engineering. SUBSTANCE: device has rotation mechanism, handle and hollow casing. The hollow casing has articulated parts having two and more pairs of end surfaces arranged at an angle to longitudinal casing axis for conjugating to hollow axle. The hollow axle is arranged in perpendicular to the end surfaces. The rotation mechanism has rotating shaft in the inside of the casing and working jaws. The rotating shaft is mounted in proximal casing area with respect to handles. Driven shaft is mounted in deviating part of the instrument. The shafts have gears at their ends being in constant engagement at any rotation angle. The working jaws are engageable with the driven shaft via the screw transmission and hinge system via conic gears. The driven shaft has movable working jaws or one movable jaw. EFFECT: wide range of functional applications; reduced risk of traumatic complications. 5 cl, 12 dwg
