FIELD: medical engineering. ^ SUBSTANCE: device has cylindrical uterine dilator. The dilator is manufactured from super-elastic material on the base of titanium nickelide as zigzag wire spiral rolled as cylinder and having end zigzag segments bent to 15-30° outwards. One or several distal zigzag end segments are elongated by 0.5-0.7 times cylinder diameter, closed and twisted and smoothly conjugated when being bent into cylindrical lumen in inclined position relative to its axis. ^ EFFECT: enhanced effectiveness of cervical canal dilation; simplified method for withdrawing the device. ^ 1 dwg |
