Description

Uterus line cutter

Technical Field

The invention relates to the technical field of gynecological medical instruments, in particular to a uterus line cutter for cutting a uterus after cutting the vagina fornix in vitro in a laparoscopic total hysterectomy.

Background

Total hysterectomy is a common gynecological procedure. With the continuous development of medical technology, the full hysterectomy under the laparoscope is gradually developed and matured, and the operation generally selects the uterus of less than 12 gestational weeks. The minimally invasive society of China defines the uterus with the gestational period of more than or equal to 12 as the large uterus. In recent years, surgeons skilled in laparoscopic techniques have gradually developed laparoscopic major hysterectomies. With the continuous improvement of laparoscopic surgical techniques, more and more surgeons are performing laparoscopic hysterectomy of the large uterus. However, after the oversized uterus is isolated, it is difficult to remove it from the vagina. The existing method is to split or cut the uterus into pieces and take out the pieces from the vagina with a scalpel or scissors, the bigger the uterus is, the more difficult the uterus is to be decomposed, the operation process is time-consuming and labor-consuming, and bleeding, vaginal stump tearing, bladder injury, intestinal canal injury and the like can be caused sometimes. The use of vaginal uterine electrorotary cutter has also been reported, which requires purchase of instruments, has high cost, low safety and cost performance, and has not been popularized yet. Therefore, the development of laparoscopic hysterectomy requires a low-cost cutting instrument that is easy and convenient to operate and easy to popularize.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a transvaginal uterus linear cutter which has the advantages of simple structure, novel conception, convenient operation, low manufacturing cost, simple and convenient operation process, safe and quick cutting of the separated uterus, one or more times of longitudinal dissection of the uterus, easy taking out of the uterus from the vagina, labor saving and labor saving in operation and avoidance of vagina injury.

The invention relates to a uterine tube cutter, which comprises a circular cup body 1 and cutting lines 3, wherein through holes 2 are symmetrically and longitudinally arranged on two sides of the cup wall of the circular cup body 1, and two ends of each cutting line 3 penetrate through the through hole 2 on one side, so that the cutting lines 3 are distributed in a U shape.

And the middle section of the cutting line 3 is provided with cutting teeth 8.

Two ends of the cutting line 3 are respectively provided with a pull line ring 4.
