(Uterine) endometrial multiple polyps are not treated satisfactorily with Hai Fu Knife. Helioblade is a high-intensity ultrasound focused tumor treatment system, the principle of which is that under the guidance of ultrasound or nuclear magnetism, the low intensity ultrasound waves outside the body will be focused in the process of penetrating the tissues to form a focal point of high energy density in the target area, which will lead to rapid heating of the tissues in the focal point area and coagulative necrosis, and then the necrotic tissues will be absorbed by the body mechanically. The surgery is suitable for single benign tumors with size not more than 5 centimeters, such as single uterine fibroid, adenomyoma with size not more than 5 centimeters are the good indications for Hai Fu Knife, and the surgery is non-invasive and the postoperative recovery is fast. For the multiple endometrial polyps, it is not suitable to apply the sea knife treatment, because it is a wide range of lesions, it is not easy to locate the focus, can not achieve the effect of elimination; and endometrial polyp treatment can be in the hysteroscopic electrocautery, it is non-invasive surgery does not need to use the sea knife. Women suffering from multiple endometrial polyps must go to a regular hospital to consult a specialist to choose the appropriate treatment.
