Description

  This utility model relates to the field of medical equipment, and in particular to a disposable collection bag for laparoscopic hysteromyoma crushing.

  Laparoscopic gynecological minimally invasive surgery is performed in the abdominal pelvic cavity, and the doctor operates the surgical instrument inserted in the abdominal pelvic cavity outside the abdominal cavity while looking directly at the monitor screen. Finalize. Laparoscopic hysterectomy or uterine fibroid enucleation involves laparoscopic removal of the uterus or fibroid, followed by cutting and crushing the tissue in the abdominal cavity with a high-speed rotating blade of a fibroid crusher. The diseased tissue is removed from the incision.

  According to an analysis by the US Food and Drug Administration (FDA), undetected uterine sarcoma is found in 1 in 350 cases of hysterectomy or hysteromyconucleation. This is because high-speed rotating blades can disperse tumor tissue in the pelvis and abdominal cavity, leading to cancer cell dissemination, greatly reducing the likelihood of patient survival.

  In order to reduce the dissemination of the diseased tissue and reduce the risk of transmission in the abdominal cavity and pelvis, some clinical medical institutions have tried using collection bags in the crushing procedure. Currently, surgical disposable collection bags are made of medical polymer material into a cylinder shape, placed in the front sheath rod, can enter the surgical area smoothly through the sheath, and are collected by a soft memory wire expansion device The bag mouth of the bag can be widened. If the excised material is stored in a collection bag and the excised material is soft and the volume is relatively small, pull the handle of the inner sheath outward to pull the bag port of the collection bag into the outer sheath rod and puncture tool. Store and remove the collection bag from the body at the same time with the excised collection bag. If the excised material is soft but the volume is relatively large, fold the inner sheath rod of the extraction tool, extract the outer sheath rod and the puncture tool, and perform surgery. After the collection bag is exposed outside the cut end, it can be spread out, and it can be taken apart by forceps in several times.

  However, in such a collection bag: 1. The collection bag is not opened completely by the abdominal cavity and is accidentally cut by the rotating blade head. 2. When the tumor tissue is rotationally excised, because the bag mouth is in an expanded state, some of the tumor tissue is still scattered outside the bag and enters the abdominal cavity. Since water vapor easily accumulates on the bag wall, there are problems such as poor visibility when observing through the bag, and important organs in the abdominal pelvic cavity are accidentally damaged by the rotating blade head.
