Abstract
A bionic cervix uteri dilator comprises a power supply circuit, an oscillating circuit, a voltage step-up circuit and curing electrodes, wherein the output terminal of the power supply circuit is connected to the input terminal of the oscillating circuit the output terminal of the oscillating circuit is connected to the input terminal of the voltage step-up circuit, and the output terminal of the voltage step-up circuit is connected to the curing electrodes. The present invention has advantages of novel structure, safety and reliability. With a narrow pulse of frequency 1-200 Hz (being preferably selected from 5 to 150 HZ, further being preferable in between 5-50 HZ.) outputted on the output terminal, the cervix uteri can be effectively dilated by stimulating ear acupoints, so that gynecological diseases treatments can be facilitated, and the pains caused by cervical dilating by the use of instruments can be alleviated. The present invention is worth widely popularizing and utilizing.
