Problems solved by technology

For malignant uterine tumors such as uterine sarcoma, it is difficult to quickly distinguish them from uterine fibroids during surgery. For example, tumor fragmentation with a tumor fragmentation device may increase the risk of sarcoid pelvic-peritoneal metastasis, and at the same time significantly reduce the patient's disease-free survival and overall survival. catastrophic for patients

Embodiment Construction

[0017] Combine below figure 1 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not as a limitation to the present invention.

[0018] Such as figure 1 , the present invention provides a disposable anti-spread tumor fragmentation device, which includes a sleeve 1 placed in the incision of laparoscopic surgery. The sleeve can be made of medical materials such as hard silica gel or plastic, and the sleeve extends into the One end of the incision is provided with a bagging 2, and the bagging is generally made of flexible materials, such as medical silica gel, rubber, etc., and is disposable, which not only can avoid cross-infection, but also facilitates collection. The backguy 3 that passes through from this sleeve pipe other end is connected with described sleeve bag. During the implementation, when the tumor is put into the bag, the pulverizer 4 penetrates throug...

Abstract

The invention relates to medical instruments, in particular to a disposable dissemination-preventing and tumor-smashing device. The device comprises a cannula arranged in an incision of an endoscopicsurgery; a sleeve bag is arranged at the end, extending into the incision, of the cannula; a pull wire penetrating through the other end of the cannula is connected with the sleeve bag; and after a tumor is put into the sleeve bag, a smasher extends into the sleeve bag from the cannula through a bag opening of the sleeve bag, and then the bag opening is tightened by pulling the pull wire, so thatthe smasher smashes the tumor in the sealed sleeve bag. The simple cannula, sleeve bag and pull wire are adopted, and the tumor can be wrapped and smashed in the sealed sleeve bag through the existingsmasher; the device is ingenious in design, simple in structure and convenient to operate; and the crushing process is good in leakproofness, so that tumor dissemination and planting can be effectively prevented.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable anti-spread tumor fragmentation device. Background technique [0002] Uterine fibroids are the most common benign tumors in women of reproductive age. Surgical treatment is often recommended for symptomatic patients with uterine fibroids. With the development of laparoscopic technology, larger tissues can be taken out through small incision electric pulverization, which avoids the extension of incision and shortens the operation time. More and more patients with uterine fibroids choose laparoscopic surgery. But there are more and more complications caused by laparoscopic electric morcellator. In 2014, the US Food and Drug Administration (FDA) issued a warning on the use of tissue morcellators in laparoscopic uterine fibroid surgery: it is not encouraged to use laparoscopic electric morcellation to remove the patient's uterus or uterine fibroids, especially It is for patients sus...
