摘要：
The invention relates to a negative pressure drainage device attached to dental tissue. The negative pressure drainage device has a negative pressure machine, a negative pressure tester, a negative pressure control valve and a sealing part. The negative pressure machine is connected to the negative pressure tester, the negative pressure tester is connected to the negative pressure control valve, and the negative pressure control valve is connected to the sealing part through a connecting part. The device, by using the apical foramina structure of the dental tissues per se, cannot only drain and form negative pressure in the cyst cavity, but also no longer need a long-term implantation of a negative pressure drainage artificial device in the jaw.
