Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an adsorption forceps for taking out a huge uterus.
Background
Clinically, uterine fibroids and adenomyomas are common benign tumors in gynecology, and the diseases often cause uterine enlargement, and cause clinical manifestations of lower abdominal mass, abnormal uterine bleeding, lower abdominal pain, large leucorrhea and the like. In the face of huge uterus, for perimenopausal women with the requirement of no fertility, the traditional operation mode usually selects a transabdominal total hysterectomy operation. With the popularization of minimally invasive concepts, more and more gynecologists choose to resect a large uterus by laparoscopic surgery. Laparoscopic surgery is a common minimally invasive surgery mode at present, and is widely accepted by doctors and patients due to the advantages of small incision, clear surgical field, less bleeding during surgery, quick postoperative recovery and the like. However, how to successfully remove the huge uterus through the vagina becomes a practical problem for many gynecologists. Traditional transvaginal uterine extraction methods: the assistant vagina draw hook fully exposes the vaginal stump and exposes the excised cervical tissue, the left hand of the main knife clamps the cervix by using cervical forceps or cloth-towel forceps, and the right hand of the main knife cuts the uterus body along the center by using a scalpel close to the vaginal incising edge or cuts the uterus body by wedge-shaped blocks, thereby taking out the uterus smoothly through the vagina.
In the face of a large uterus, the traditional transvaginal withdrawal mode has drawbacks: for the irregularly enlarged uterus, the uterus is cut or resected in a block shape along the median line, the requirement on the operation skill of an operator is high, the size and the position of the uterus need to be fully known before resection, the consumed time is long, the uterus can not be completely removed in one time, and the uterus needs to be continuously rotated to a corresponding position, such as the position of a posterior fornix, so that the isolated tissue can be smoothly removed; in the process of excision, the abdominal cavity with the easily dropped uterus needs to be delivered to the vaginal stump with the assistance of the laparoscope again. The technique is not easy to master, and the excess force or uneven stress in the traction process is easy to damage the stump and the vaginal wall, which leads to the bleeding of the stump and the massive bleeding of the abdominal cavity caused by injuring the parauterine artery, etc.
