Background

Modern medical technology is rapidly developed, the average life of human beings is gradually prolonged, and the treatment requirements of people on diseases are not only satisfied with the curative effect, but also the requirements on the quality of life after treatment are higher and higher. Therefore, in addition to considering the treatment of the disease itself, there is more concern about selecting a more minimally invasive approach to ensure a higher quality of life after surgery, both in doctors and patients, which also motivates surgeons to continually seek less invasive, faster recovery surgical approaches.

In the gynaecological field, laparoscopic surgery has become one of the main surgical modes, especially in gynaecological benign diseases, which is a safe and reliable mainstream choice. In recent years, along with the continuous improvement of laparoscopic surgery technology and the increasingly updated surgical instruments, the application range of laparoscopic surgery is continuously expanded, benign to malignant tumors are covered, and the development of single-port laparoscopic surgery through umbilicus and single-port laparoscopic surgery through vagina is also in rapid progress. Compared with the traditional operation, various laparoscopic operations have smaller wounds, more concealed and beautiful incisions, are favored by female patients, and are more and more favored by gynecologic surgeons. The operation of various accessory (accessory refers to oviduct, ovary) swellings is a considerable proportion of gynecological laparoscopic surgery, involving benign tumor and malignant tumor operations. For women without menopause, the accessory tumor operation often needs to be stripped off, and whether the operation range needs to be enlarged is determined according to the pathological result in the operation. When the accessory tumor is peeled off, an operator needs to lift or fix the accessory tumor by using pliers, then an ultrasonic knife or scissors or other professional instruments are selected to cut a small opening at a relatively thick part of the ovarian cortex to the tumor coating layer, the tumor is gradually and completely separated and peeled off, finally the object taking bag is placed into the abdominal cavity from the puncture hole of the laparoscope, the peeled off tumor is placed into the object taking bag, and then the object taking bag can be taken out from the incision, so that the tumor is taken out. If the tumor size is large and can not be taken out from the incision, the tumor can be penetrated into the object taking bag by scissors to puncture the tumor, the cyst fluid is sucked out, and the solid tumor is taken out in small blocks. The tumor is broken in the isolation protection bag all the time, so that the tumor tissue is not scattered into the body and the tumor is not spread.

However, approximately half of the accessory tumor patients may experience intraoperative tumor rupture, particularly in laparoscopic surgery. When the tumor is peeled or resected, the tumor is required to be prevented from moving, so that the tumor is kept in a relatively fixed state, and the operation of cutting and separating the tumor is convenient. In the prior art, pliers are usually used for lifting or clamping the surface of a tumor, so that the tumor is often broken due to the fact that the tumor envelope is too thin or is stressed unevenly or is forced improperly, and the risk that the cyst fluid or cyst contents containing tumor cells overflows and the tumor is transferred in the pelvic cavity and the abdominal cavity is caused, so that the prognosis of a patient is influenced. That is, the prior art has the problems of easy tumor rupture and tumor spreading and metastasis when adopting pliers to stabilize or lift the tumor under the condition of no protective measures.
