Technical Field

The utility model relates to the field of medical equipment, especially an endoscope cutting electrocoagulation device that coincide and mechanism that coincide thereof.

Background

In recent years, laparoscopic surgery has been widely used in clinic, and with the rapid development of technology, laparoscopic surgery has also taken an important position in gynecological tumor surgery. Laparoscopic hysterectomy is one of the most common gynecological procedures. The treatment of a sutured vaginal discontinuity is one of the key steps in the overall procedure. The current conventional means is to use an electrosurgical instrument or ultrasonic blade to sever the vagina, which has 2 disadvantages. Firstly, the hemostatic effect of the electrical appliance is not exact when the vagina is disconnected, and the larger blood vessels beside the vagina or on the vaginal wall are not closed completely, so that bleeding is caused, and the visual field of the operation is influenced; second, when the vagina is not closed, tumor cells may fall off from the cervix or uterine cavity to the pelvic cavity, and cause graft metastasis in other parts along with pneumoperitoneum of carbon dioxide, which affects the prognosis of the patient. Some doctors use a laparoscope linear cutting anastomat to break the vagina to avoid exposing tumor cells, but the cutting closer is bidirectional, the broken end and the stump of the vagina are simultaneously closed, and if a specimen is taken out of the vagina, the anastomosis nail at the stump of the vagina must be removed, so that the operation time is prolonged. Therefore, there is a need for a device that can achieve both side anastomosis and side non-anastomosis with hemostasis.

The existing electrocoagulation cutter on the market can solve the problem of vaginal incisal edge bleeding, but can not realize closed cutting, and has the risk of exposing tumor cells; the disposable endoscope linear cutting anastomat can cut and break the vagina in a closed manner to avoid exposing tumor cells, but is closed in a two-way manner, and an anastomosis nail at the residual end of the vagina must be removed when a specimen is taken, so that the operation time is prolonged.
