[0002] Laparoscopic myomectomy is a common minimally invasive gynecological surgery. It makes several small incisions in the abdomen, inserts a laparoscope and surgical instruments, and directly removes uterine fibroids from the uterus while preserving the integrity of the uterus. This surgery has the advantages of small trauma, less bleeding, fast recovery, short hospital stay, and beautiful abdominal incisions, and has become one of the main methods for treating uterine fibroids, being deeply favored by patients and doctors. In the prior art, the method of removing the tumor is to place the fibroid in a sterile retrieval bag, drag the bag mouth out from a small abdominal wall incision, and then gradually cut the fibroid tissue with a blade. However, this method has the following problems: during the cutting process, it is easy to cut through the sterile bag, resulting in the fibroid falling into the abdominal cavity, posing a risk of fibroid dissemination and causing adhesions, which does not conform to the principle of tumor-free surgery. At the same time, if the fibroid is large, it is time-consuming and laborious to remove, and it is difficult to cut. Often, the abdominal wall incision needs to be enlarged, damaging the integrity and strength of the abdominal wall, not only increasing the damage to the patient but also affecting the postoperative aesthetics. Therefore, in view of the above problems in the prior art, this solution proposes an auxiliary tumor removal device during laparoscopic myomectomy. Summary of the Invention
