Abstract: With the improvement of medical techniques and increase in the awareness of reproductive health，more and more patients with fibroids require uterine sparing，and myomectomy is favored. Due to widespread use of laparoscopy and ignorance of tumor-free principle，there have been frequent occurrences of widespread dissemination and planting of parasitic fibroids，even sarcomas，in the abdominal cavity recently，which seriously endanger women's life and health，becoming a significant public health issue.The U.S. FDA issued a black box warning about power morcellation for myomectomy. Therefore，it is imperative to establish the tumor-free strategy. Aiming at the multi-cause of iatrogenic tumor metastasis in myomectomy and emphasizing medical education as the basis，hospital management as the guarantee，scientific and technological innovation as the guidance，we build an all-round and multi-level safety prevention and control barrier，pay attention to detail management，and take corresponding measures to prevent tumor exposure，tissue debris spread，and body fluid or blood pollution，so as to ensure the safety of patients after myomectomy.

Key words: tumor-free strategy, myomectomy, minimally invasive, containment system, port site metastasis
