Traditional abortion surgery, the doctor can not see the shape of the uterine cavity, completely under blind vision to do this operation, so there is a lot of blindness, easy to lead to incomplete suction, leakage of suction and other complications occur. So now the safer abortion methods are as follows: first, abortion under the B ultrasound, is a doctor in the belly above the B ultrasound, and then the B ultrasound can completely see the embryo in the uterine cavity location, size, the following a doctor in the operation, will follow the ultrasound to check the situation of the embryo began to attract, this is a safer abortion method. Secondly, the ultra-guided visual microtube, using a suction tube with a camera to enter the uterine cavity, there is a TV screen next to the operating table, when the suction tube enters the uterine cavity, the TV screen will clearly show the shape of the uterine cavity, the doctor can see where the embryo is in the uterus, and then attract to this embryo, this will be very safe, and the damage to the uterus is also very small.
