The effect of uterine fibroids treatment with Hai Fu Knife is better. The effect of uterine fibroids treatment with Hai Fu Knife is affirmed clinically. Hai Fu Knife treatment does not require abdominal opening, recovery is fast, patients can be hospitalized without hospitalization, and it can reduce the intraoperative adhesion to a certain extent, and patients with fertility requirements can prepare for pregnancy six months after the operation. Hai Fu Knife is a new technology for the treatment of uterine fibroids. Its principle of action is to use the properties of ultrasound, focusing low-energy ultrasound waves on the fibroid, which, when reaching a certain intensity, can cause the fibroid to denature, liquefy, necrosis and absorption. Fibroids located under the mucosa may be discharged directly through the vagina after treatment. However, there is still the possibility of fibroid recurrence or residual fibroids in the treatment of fibroids by Hai Fu Knife. In addition, a biopsy of the fibroid is required before the operation to rule out the possibility of malignant changes before Hai Fu Knife treatment is carried out, and it is recommended that the patient go to a regular hospital for treatment.
