A self-locking tourniquet for laparoscopic myomectomy

Abstract

The invention discloses a tourniquet for laparoscopic myomectomy with a self-locking function, which includes an elastic contraction band and a self-locking buckle fixed on one end of the elastic contraction band. The self-locking buckle includes a self-locking buckle. The main body of the self-locking buckle has a self-locking hole at one end connected to the elastic shrinkage tie for the other end of the elastic contraction tie to pass through and lock the elastic contraction tie. The other end of the self-locking buckle body There is an open self-locking slot, the outer end of the open self-locking slot is in the shape of a figure eight, and stop openings are fixed on both inner sides of the open self-locking slot, and the two stop openings are arranged oppositely. The invention has reasonable structural design, convenient use and operation, low cost, can ensure the integrity of the uterus, reduce the probability of conversion to laparotomy, reduce or eliminate the possibility of blood transfusion, avoid the impact on ovarian function and reproductive function, and make it easier for patients to recover and can It can significantly reduce bleeding during myomectomy, which is more advantageous for complex surgeries such as larger uterine fibroids and multiple fibroids.

Description

A self-locking tourniquet for laparoscopic myomectomy technical field The invention relates to a medical tourniquet, in particular to a tourniquet for laparoscopic myomectomy with self-locking function. Background technique 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, beca...

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
