In one embodiment, a switch is provided near the drainage port.

In one embodiment, the first plug is provided with an injection hole passing through the first plug, and the first plug is further provided with a second plug capable of covering the injection hole.

In one embodiment, the diameter of the three-terminal puncture catheter is 7-9 mm, and the width of the widest part of the spatula is 5-7 mm.

Advantage and beneficial effect of the present utility model are:

The utility model can not only drain the pus through the negative pressure drainage device, but also when a new pus cavity is formed around the abscess cavity, use a spatula to destroy the separation of the abscess cavity through the operation port of the puncture catheter, unobstructed drainage, and scrape out the part Non-liquefied necrosis, and the spatula can be operated repeatedly, so the trauma to the human body is small, the operation is convenient, and the treatment cost is relatively low, specifically:

This device only needs to make a small incision on the mammary gland skin, and the puncture is less traumatic, avoiding the large incision of traditional surgical incision and drainage, and there are multiple side holes at the end of the abscess, which can effectively drain pus and avoid Disadvantages of incomplete pus aspiration by fine needle aspiration;

This device can be inserted into the spatula through the operation port. Under the guidance of color ultrasound, it can not only effectively destroy the separation of the abscess cavity, but also destroy the incompletely liquefied tissue in the abscess cavity, and after the initial treatment, it can be repeated several times for the newly formed abscess cavity around the original lesion. Operate through the operation port for the first time.
