Vaginal closer for laparoscopic hysterectomy

Abstract

The invention discloses a vaginal closer for laparoscopic hysterectomy. The vaginal closer comprises a power structure, a shell, a fixed handle and a movable handle, wherein one end of the shell is fixedly connected with a power cavity, the power structure is movably inserted into the power cavity, and the power structure is arranged in the shell. According to the vaginal closer for laparoscopic hysterectomy, the problem of tumor exposure when the uterus and the vagina are cut off in laparoscopic surgery for endometrial cancer or early cervical cancer is solved through the designed closer with a special structure, the closer extends into the abdominal cavity of a patient along a puncture hole, before the uterus and the vagina are cut off, the vagina is horizontally clamped by a closed cutting structure at the front end, the upper part of the vagina is closed by the closer, meanwhile, the lower vagina is cut off, the stump is kept open, the uterus and other specimens are taken out from the stump, then the vaginal stump is sutured, the potential risk of iatrogenic dissemination in the operation process is reduced, the non-tumor principle is realized, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vaginal closure device for laparoscopic hysterectomy. Background technique [0002] The application of laparoscopy has matured in the treatment of many gynecological diseases, including some gynecological malignancies such as early cervical cancer and endometrial cancer. Among them, in the operation involving total hysterectomy, the "no-tumor principle" has been the focus of attention in recent years. Whether it is early cervical cancer or endometrial cancer, when laparoscopic uterine and vaginal dissection is performed, the process of incising the vaginal wall may cause the tumor lesions to be completely or partially exposed to the pelvic and abdominal cavity. Spread planting within. At present, in clinical practice, some surgeons perform cerclage on the vagina before the uterus and vagina are separated through silk thread or autolyzed thread or plastic tie tape. Le...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a vaginal closer for laparoscopic hysterectomy, which solves the problem of tumor exposure during laparoscopic surgery for endometrial cancer or early cervical cancer when the uterus and vagina are severed. The problem is that the occluder is inserted into the patient's abdominal cavity along the puncture hole. Before the uterus and vagina are separated, the closed cutting structure at the front end is used to clamp the vagina horizontally. The stump is opened, and the vaginal stump is sutured after taking out the uterus and other specimens from the stump, which reduces the potential risk of "iatrogenic dissemination" during the operation and realizes the "tumor-free principle"

At the same time, most medical auxiliary devices are inconvenient to place after use, and the operation is not convenient enough, which is not conducive to sorting and summarizing medical auxiliary devices, and there are certain limitations in application.
