Description

Disposable uterine fibroid tumor breaking protection device under laparoscope

Technical Field

The utility model relates to a medical instrument, in particular to a disposable hysteromyoma and tumor breaking protection device under a laparoscope.

Background

Laparoscopic hysteromyoma removal is a common minimally invasive surgical method at present, and specifically comprises making 4 skin incisions of 0.5-1.0cm on the abdomen, establishing an operation channel through a puncture outfit, and removing hysteromyoma by means of a facilitated surgical instrument. The hysteromyoma removal operation under the laparoscope has the advantages of small wound, attractive appearance, light pain of a patient and quick recovery.

After the hysteromyoma is cut off, how to completely take out the specimen without leakage is a difficult problem in clinic at present. Most of the existing methods are unprotected broken tumors, which can cause the planting and dissemination of myomas, and if the myomas are malignant, iatrogenic tumors can be upgraded in stages, thereby bringing irreparable consequences to patients. Based on this, the us FDA has banned the use of tumor breakers clinically to break up fibroids. Some students enlarge the incision when taking the sample, but the method has greatly reduced the advantages of the laparoscopic minimally invasive surgery, and for myoma with larger volume, the sample still needs to be taken a lot of time after a certain incision is enlarged.

Although the FDA in the united states prohibits the use of tumor crushers, it is still widely used in europe, asia, etc., outside the united states. Because the myoma specimen is taken out in a tumor crushing mode, the operation efficiency can be obviously improved, and the operation time is shortened. In fact, the tumor breaking device is not a crime, and the tumor breaking device without protection is a problem. In order to avoid the spreading of the myoma in the process of breaking the myoma, a method of filling the myoma into a specimen bag and then breaking the myoma is adopted by scholars. The problems are that the myoma is difficult to load when the size is too large, the space for crushing the myoma is narrow, and the operation is not safe and time-consuming. In addition, because the specimen bag is not completely closed, myoma fragments splash in the process of tumor crushing, and the myoma fragments still have the possibility of scattering into the abdominal cavity of the basin.

The breakthrough point for solving the problem of unprotected tumor breaking is as follows: 1. the myoma with larger volume can be conveniently packed into a bag; 2. there is a sufficiently large enclosed volume of the aneurysm.
