Experiences with the vibrodilatator of the Soviet Union

The vibrodilatator developed in the Sovet Union works on the principle of transforming 50 Hz electric frequency to mechanical vibrations of 100 Hz with the aid of an electromagnetic vebrator. The end-piece has a vibration amplitude of 1.5-2 mm. Dilatation lasts about 10 seconds depending on the rigidity of the uterus. Sound measurements of the uterus must be made before the procedure is stanted since the dilatator is inserted deep (7-9 cm) into the uterus. There are 3 dilatator sizes. The complication rate is decidedly decreased with this method since the risks of bleeding cervix rupture and perforation are minimal. The advantges for the patient are in fact so great that the vibrodilatator method should replace every other dilatation procedure.
