Description
Technical Field
The present invention relates to the field of medical devices, and more particularly, to a vaginal closure system that can be used laparoscopically.
Background
Laparoscopic surgery is a newly developed minimally invasive method and is a necessary trend for the development of future surgical methods. With the rapid advance of industrial manufacturing technology, the fusion of related disciplines lays a firm foundation for the development of new technology and new method, and the more and more skillful operation of doctors makes many of the past open operations replaced by the intracavitary operations, thereby greatly increasing the operation selection opportunities. The laparoscopy technology is that 3-5 small incisions of 0.5-1cm are made on the abdomen of a patient, a channel-shaped working channel called trocar is inserted into each incision, and all subsequent operations are performed through the 3-5 channels; and then special lengthened surgical instruments are used for completing the same steps as the open surgery under the television monitoring, so that the same surgical effect is achieved. The laparoscopic surgery has very small scars, which is more noticeable for young people and beauty-conscious women. Secondly, the operation is a single-knife straight-in entry, the damage to surrounding tissues is reduced to the minimum, and the chance of postoperative adhesion is reduced. Third, the patient had significantly reduced pain from post-operative wounds. Fourthly, the number of hospital stay days is small, some patients can be discharged after 2-3 days, and the patients can completely recover health and put into operation after 7 days, so that the burden cost of the patients is greatly reduced, and the turnover rate of hospital beds is accelerated.
Cervical cancer is the most common gynecological malignancy. The age of the primary cancer is 30-35 years old, the invasive cancer is 45-55 years old, and the incidence of the primary cancer tends to be younger in recent years. The widespread use of cervical cytology screening in recent decades has made cervical cancer and precancerous lesions early in detection and treatment, and the incidence and mortality of cervical cancer has decreased year by year. The operation is mainly used for early cervical cancer patients. The common operation includes total hysterectomy; sub-extensive hysterectomy and pelvic lymph node debridement; extensive hysterectomy and pelvic lymph node debridement; peri-aortic lymphadenectomy or sampling. Different operation formulas are selected according to different stages of patients.
Clinical studies show that: compared with the traditional wide hysterectomy with abdomen opening, the wide hysterectomy for cervical cancer, which is currently performed by most gynecological tumor doctors in the industry, has higher recurrence rate of tumors and poor prognosis. The reasons for this study may be the following: 1. CO in endoscopic surgery2The cause of pneumoperitoneum; 2. the reason why the use of the uterine lifting cup in the cervical cancer operation extrudes the local focus of the cervix; 3. the reason why the tumor tissue of the cervix is exposed to the abdominal cavity when the electric knife cuts the vaginal wall is near the end of the operation.
How to improve the existing technology in hysterectomy and avoid the probability of tumor recurrence, a proper operation system cannot be found in the prior art.
