Title:
NEGATIVE PRESSURE DRAIN DEVICE ATTACHED TO TISSUE OF TOOTH
Document Type and Number:
WIPO Patent Application WO/2017/124730
Kind Code:
A1
Abstract:
Disclosed is a negative pressure drain-device attached to the tissue of a tooth, comprising negative pressure machines (001, 101, 201), negative pressure testers (002, 102, 202), negative pressure control valves (003, 103, 203), and an enclosed part. The negative pressure machines (001, 101, 201) are connected to the negative pressure testers (002, 102, 202). The negative pressure testers (002, 102, 202) are connected to the negative pressure control valves (003, 103, 203). The negative pressure control valves (003, 103, 203) are connected to the enclosed part by interconnecting pieces (004, 104, 204). Passing through an apical pore structure of the tissue of a tooth per se can both perform drainage and form negative pressure in the cyst cavity. At the same time, there is no longer a need for long-term implantation of artificial devices for negative pressure drainage in the jaw, wherein same can greatly shorten the treatment cycle, reduce the chance of infection, reduce trauma and mouth discomfort, improve the clinical efficacy for treatment of odontogenic related diseases, and has achieved a very good effect in practice.
