Surgical system

technical field

The present disclosure relates to the technical field of medical devices, and in particular, the present disclosure relates to a surgical system.

Background technique

For women of childbearing age, endometrial polyps, uterine fibroids and intrauterine adhesions are very common gynecological diseases. These diseases can cause abnormal uterine bleeding, menorrhagia leading to hemorrhagic anemia, and infertility and other symptoms. Women's physical and mental health caused great damage. Among women of reproductive age, the prevalence of endometrial polyps is as high as 20%-25%. The incidence of uterine fibroids is 25%-30% (of which submucosal fibroids account for 10%-15% of uterine fibroids).

The power system for endoscope used in hysteroscopic surgery is suitable for intrauterine surgery performed by trained gynecologists under hysteroscope to remove intrauterine tissues including submucosal fibroids and endometrial polyps.

With the development of medical technology and the wide application of endoscopic technology, hysteroscopic surgery has also developed, and the overall trend is safer, non-invasive or minimally invasive, and more efficient.

Before performing hysteroscopic surgery, the uterus is perfused with uterine distension fluid to fill the uterine cavity to form a space for operation and vision. During the operation, intrauterine tumors and polyps are removed through the planing handle, and waste fluid and tissues are removed from the body through the negative pressure suction function, and part of the uterine distention fluid is absorbed by the body, so it needs to be continuously perfused into the uterus The uterine distension fluid keeps the pressure of the uterine cavity at the preset value. However, excessive absorption of uterine distention fluid can lead to serious complications, including hyponatremia, water intoxication and other complications, and even death. Too long uterine distension time or excessive uterine distension pressure will lead to excessive absorption of uterine distention fluid.

To prevent complications of hysteroscopic surgery, it is necessary to accurately measure the use time of intraoperative uterine distension medium, uterine distension pressure, input volume and output volume, and quickly terminate when an imbalance is found. The volume is basically input by pressurized uterine distension pump, and the output is mainly based on simple down-flow, without accurate statistics on the amount of in-out volume.
