[0010] As a preferred technical solution of the utility model, the flushing and drainage pipe is specifically a soft silicone pipe with a length of 40 cm, wherein the length of the third drainage pipe section is 5 cm.

[0011] As a preferred technical solution of the present utility model, the drainage holes are specifically micropores with a pore diameter of 2 mm.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting up the puncture needle body, it is convenient to guide the flushing and drainage pipeline into the patient's perianal abscess, and then the puncture needle body is inserted out, and the third drainage tube section of the flushing and drainage pipeline is left in the abscess, and flushing or drainage is performed through the drainage hole. The abscess is drained by the second drainage tube section in cooperation with the control valve, the negative pressure drainage ball and the negative pressure drainage ball pipeline. The puncture needle body is conveniently disassembled through the first internal thread and the first external thread, and the flushing and drainage pipeline is left in the patient's abscess, so as to facilitate multiple drainage and flushing. After removing the puncture needle body, the external flushing equipment can be connected to the first drainage tube section to flush the inside of the abscess. In summary, the device is convenient to be left in the patient's abscess, its hardness is relatively small, and it is not easy to cause discomfort to the patient, thereby avoiding multiple puncture flushing and drainage and reducing the patient's pain.
