How to avoid pulling out the radish and bringing out the mud during puncture interventional surgery?

Not only people think this way, but many colleagues in the industry also believe that "puncture can easily cause tumor metastasis", which is a misunderstanding that has been formed for a long time.

First of all, there are tens of millions of primitive tumor cells in the human blood circulation, but they are cleared by the immune system in time every day, and cannot really form tumors. The tumor cells brought out by the puncture needle are very few, far less than the number in the normal blood circulation of the human body, so the chance of metastasis is very small.

Secondly, the concept of puncture biopsy and the instruments used have also been improved in recent years, and the practice of directly puncturing the tumor and then pulling it out of the body has gradually been eliminated. At present, there is a protective jacket outside the device for puncture and material collection. The instrument is like a ballpoint pen. After the outer pen holder is attached to the surface of the tumor, press the switch to let the refill inside the pen holder pierce into the tumor body. into the barrel. Since the pen rod punctured into the body does not contact the tumor, the puncture needle avoids the leakage of tumor cells during the process of pulling out the puncture needle, and protects the human body to the greatest extent. Therefore, it can be said responsibly that the current puncture technology will theoretically not lead to the occurrence of tumor metastasis.
