Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly, to a tumor extractor for uterine fibroids surgery. Background Art

[0002] Uterine fibroids are the most common benign tumors in gynecology. The annual number of myomectomy surgeries is huge. In the past, laparotomy was performed, but now more than 90% of them are basically completed under laparoscopy. However, in gynecological laparoscopic surgery, the extraction of large and awkwardly located uterine fibroids is a challenge. Due to the limited space in laparoscopic surgery, when doctors perform myomectomy operations, they are faced with limitations in the pulling angle and direction. Especially, the tip of the laparoscopic instrument is small, and the clamping force and pulling force are far less than the direct pulling of the hand and traditional instruments (such as allis forceps and towel clips) used in laparotomy, resulting in inferior force application and convenience of the instrument during laparoscopic uterine fibroid resection compared to traditional laparotomy.

[0003] Especially for larger fibroids, lateral broad ligament fibroids, and fibroids in the lower uterine segment, the exposure and dissection process of existing digestive tract uterine fibroid extraction devices is more difficult, time-consuming, and prone to more bleeding. In addition, the design of existing instruments often fails to fully consider the special requirements in the laparoscopic surgery environment, such as force conduction and angle adjustment.

[0004] Therefore, there is an urgent need for a tumor extractor for uterine fibroids surgery to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a tumor extractor for uterine fibroids surgery, which has a simple structure and is easy to use, and can ensure the surgical field and wrap and limit the uterine fibroids.
