Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
The working principle is as follows:
taking a total-resection operation of the uterus as an example,
1. taking a bladder lithotomy position, conventionally disinfecting and paving a towel, observing the length of a vagina, adjusting the relative position between a central guide rod and a central sleeve according to the required excision length of the vagina, selecting whether a fixed sleeve and a gasket are required to be sleeved on a uterine lifting cup or not according to the distribution condition of tumors, and not needing to sleeve a gasket and the fixed sleeve if the excision or excision of less vaginas is not required; if a certain length of vagina needs to be cut, the fixing sleeve or the gasket and the fixing sleeve are clamped on the uterine lifting cup according to the required cutting length of the vagina, the uterine lifter enters through the vagina after adjustment, the upper edge of the uterine lifting cup is attached to the cervix and the fornix of the vagina, the lower end of the cervix enters the uterine lifting cup, the insertion end of the central sleeve extends into the cervix, negative pressure treatment is carried out on the uterine lifting cup, the annular air bag is filled with water or air through the air charging pipeline, when the uterine lifter completely seals and fixes the cervix, the water or the air charging is stopped, the air charging is closed, the annular air bag is ensured to keep a full state, a closed structure is formed through the uterine lifting cup and the annular air bag, annular expansion joint closure is formed, the blood flow of the focus part can be closed, and the cervical canceration part forms a closed structure;
2. inserting a needle with a 10mm incision at the upper edge or lower edge of the umbilicus to establish CO2And (3) performing pneumoperitoneum to ensure that the abdominal pressure reaches 12-15mmHg, and after puncturing by a 10mm sheath clamp, entering the laparoscope and adjusting the body position to be in a head-low hip-high position. The vaginal air bag is adjusted to be above the vaginal orifice, the first one-way valve is opened, the main air bag is inflated by continuously pressing the auxiliary air bag to form a closed structure, the escape of inflation in the abdominal cavity is prevented, and the normal operation in the pneumoperitoneum process is ensured;
3. probing the abdominal and pelvic cavities, observing the size and shape of the uterus, the condition of double attachments and whether the pelvic cavities are adhered or not, performing puncture fixation, sewing and fastening the vagina on the annular groove on the uterus lifting cup if a part of the vagina needs to be cut, cutting the uterus according to positioning, changing the air inlet direction of the first one-way valve after cutting, releasing the air in the main airbag, and taking the cut uterus out of the vagina through a handle part; the specimen is firmly sealed on the uterine lifting cup before being taken out, the uterine lifter and the extirpated uterus can be directly taken out through the vagina, tumor cells in the uterus cannot be contacted with the abdominal cavity and the vagina, the separation can be prevented when the uterine lifting cup is separated from the uterus, the scattering and planting of the tumor cells are avoided, and the recurrence of the tumor is effectively prevented;
4. the vaginal air bag is taken down and inflated again, the spherical air bag is arranged in the main air bag to form a columnar structure, the vaginal opening is blocked, the pneumoperitoneum state is kept, the pelvic peritoneum is continuously sutured, and the wound surface is embedded.
