Description

A kind of non-invasive uterine pulling forceps

technical field

The utility model belongs to the technical field of medical forceps tools, in particular to a non-damaged uterus pulling and holding forceps.

Background technique

For a long time, cervical cancer has been regarded as a high-risk and high-morbidity female cancer, threatening the lives and health of the majority of women. In 1994, the French scholar Dargent first reported the use of fertility-preserving radical trachelectomy. Since then, the concept of fertility-preserving surgery for young nulliparous patients with cervical cancer has gradually been accepted, and the surgical methods have become increasingly perfect and diversified. Radical trachelectomy mainly includes transvaginal radical trachelectomy, transabdominal radical trachelectomy and laparoscopic radical trachelectomy. But at present the most mastered by clinicians is the abdominal radical trachelectomy. Abdominal extensive cervical resection is a new cervical cancer surgery in recent years, which can be used as the first choice for the treatment of early cervical cancer patients with fertility requirements. Because the purpose of the operation is to preserve the uterus, extensive excision of the cervix is required, and the uterus must be pulled repeatedly during the operation. The key to the operation is to protect the preserved uterus, because this is the key to the patient’s fertility after surgery, and it is also safe for the operation. guarantee.

At present, two methods are commonly used to stretch the uterus repeatedly. One is to use hemostatic forceps to clamp the uterine attachments of the bilateral round ligaments to stretch the uterus; the other is to use the oval forceps (or towel forceps) directly Clamping the uterus to pull the uterus has achieved the purpose of exposing the operative field. However, among these two methods, the former uses the ligament connected to the uterus to stretch the uterus, so the pulling effect is not good and the exposure of the operative field is not obvious; however, the latter uses the injury forceps to directly pull the uterus, although the pulling effect can be guaranteed, but The small contact area of the forceps or the clamping method of the forceps tends to cause more serious damage to the uterus, and the uterus is damaged more at the place where the forceps is pinched, and the uterus needs to be pulled repeatedly during the operation to change the position, which makes the damage even greater. In severe cases, uterine avulsion bleeding will occur during the operation, leading to hysterectomy, which will adversely affect future fertility. Therefore, there is an urgent need for a surgical instrument that can not only pull the uterus, but also reduce the damage caused to the uterus.
