Description

Disposable collection bag for laparoscopic uterine fibroids

Technical field

The invention relates to the field of medical instruments, in particular to a disposable collection bag for laparoscopic uterine fibroid comminution surgery.

Background technique

Laparoscopic gynecological minimally invasive surgery is performed in the pelvic and abdominal cavity. The physician looks directly at the surveillance screen and manipulates the surgical instruments inserted into the abdominal cavity of the pelvis outside the abdominal cavity to complete the operation. Laparoscopic hysterectomy or uterine fibroids removal is performed by laparoscopically cutting the uterus or fibroids, cutting and smashing the tissue in the abdominal cavity using a fibroid rotating machine, and removing the diseased tissue through a small incision.

According to the US Food and Drug Administration (FDA) analysis, about 1 in every 350 cases of hysterectomy or hysteromyoma removal, a patient with a secret uterine sarcoma was found because the rapidly rotating blade would treat the tumor tissue. Dispersed in the pelvis and abdomen, which may lead to the spread of cancer cells, greatly reducing the chances of survival.

In order to curb the spread of diseased tissue and reduce its risk of transmission in the abdomen and pelvis, some clinical medical institutions have attempted to use collection bags in comminution procedures. At present, the disposable collection bag for surgery is made of medical polymer material as a barrel-shaped collection bag, placed in the front sheath rod, and can smoothly enter the operation area through the sheath, and the collection bag can be opened through the soft memory wire opening device. Open, the surgical resection is placed in the collection bag. When the excision is soft and the volume is small, the inner sheath handle is pulled out, the bag pocket is collected into the outer sheath rod and the trocar, and the collection bag is pulled out together with the excision. When the excision is soft but the volume is large, the sheath rod in the extractor can be broken, the outer sheath rod and the puncture device can be pulled out, the collection bag is exposed to the outside of the surgical incision, and the excision is removed by splitting the jaws.

However, this collection bag has the following problems: 1. The collection bag cannot be fully deployed in the abdominal cavity, causing the rotary cutter head to be miscutted into the collection bag; 2. The bag mouth is expanded when the tumor tissue is rotated, and some tumor tissues are still It will splash out of the bag and enter the abdominal cavity; 3. Because the wall of the bag is easy to accumulate water vapor, the view of the bag is unclear, which may cause the rotating blade to accidentally injure the important organs of the pelvic cavity.

Summary of the invention

The object of the present invention is to provide a disposable collection bag for laparoscopic uterine fibroid comminution surgery, so that the tumor tissue does not splash out of the bag, and the operation is safe.

To this end, the present invention employs the following technical solutions:
