A self-locking tourniquet for laparoscopic myomectomy

Abstract

The invention discloses a laparoscope myomectomy tourniquet with the self-locking function. The laparoscope myomectomy tourniquet with the self-locking function comprises an elastic shrinkage bandage and a self-locking stop buckle fixed to one end of the elastic shrinkage bandage. The self-locking stop buckle comprises a self-locking stop buckle body. The end, connected with the elastic shrinkage bandage, of the self-locking stop buckle is provided with a self-locking hole, wherein the other end of the elastic shrinkage bandage can penetrate through the self-locking hole, and the self-locking hole can lock the elastic shrinkage bandage. The other end of the self-locking stop buckle is provided with an opening self-locking slot, the outer end of the opening self-locking slot is splay, the two inner sides of the opening self-locking slot are provided with spigots respectively, and the two spigots are arranged oppositely. The laparoscope myomectomy tourniquet with the self-locking function is reasonable in structural design, convenient to use and operate and low in cost, integrity of the uterus can be guaranteed, the probability of conversion to laparotomy of the laparoscope is reduced, the possibility of blood transfusion is reduced or eliminated, the ovarian function and the fertility function are prevented from being affected, patients can recover more easily, the possibility of bleeding in myomectomy can be obviously reduced, and the laparoscope myomectomy tourniquet with the self-locking function has more obvious advantages for complex operations such as large uterine myomas and multiple myomas.

Description

technical field [0001] The invention relates to a medical tourniquet, in particular to a tourniquet for laparoscopic myomectomy with self-locking function. Background technique [0002] Uterine fibroids are benign tumors with a high incidence in women, with an incidence rate of more than 20%. The treatment methods include: expectant treatment, conservative drug treatment and surgical treatment. Medication can control or reduce the volume of fibroids, relieve symptoms and reduce bleeding, but it is not a radical treatment. Surgical treatment includes hysterectomy and myomectomy. Myomectomy is a surgical procedure to remove fibroids and retain the uterus. It is suitable for young patients who want to preserve their reproductive function, and it is also suitable for elderly patients who want to keep their uterus. The methods can be through laparotomy, vaginal or endoscopy. Among them, endoscopy includes laparoscopy and hysteroscopy, because of its minimal invasiveness, it has ...

Problems solved by technology

The current hemostasis methods include suturing under the microscope, uterine artery ligation and cutting, monopolar electrocoagulation, bipolar electrocoagulation, and intraoperative injection of oxytocin or pituitary hormone. These methods have the following disadvantages in the process of use: (1 ) endoscopic suturing, large uterine fibroids, especially large intramural fibroids or multiple fibroids, due to large incisions, deep tumor cavities, or multiple incisions, even with high suture skills, it will take a certain amount of time, and there will be More bleeding; (2) Ligation and cutting of the uterine artery not only requires the surgeon to be familiar with the anatomical structure of the pelvis, the operation is complicated, but also because the ligation of the uterine artery may affect the blood supply to the ovary and cause a decline in ovarian function, which is especially unfavorable for young patients; (3) )Unipolar coagulation and bipolar coagulation have limited effect due to limited energy, and hemostasis is not ideal when removing fibroids; Vomiting, rapid heart rate or arrhythmia reactions may also cause allergic reactions. When applied in large doses, it can cause high blood pressure or water retention. The half-life is 1-6 minutes, the action time is limited, and it cannot be used in large quantities; The composition and side effects of uterine, also contains antidiuretic hormone, antidiuretic hormone can constrict blood vessels, increase blood pressure, increase unsafe factors in the operation, and it is not suitable for patients with hypertension
