A plasma root canal therapeutic apparatus is disclosed, including a plasma generating space communicated with a conduit which enables ionizable gas to enter the plasma generating space an electrode, which is disposed at the periphery of the plasma generating space and is coated with a dielectric a power supply part, which is connected with the electrode, making the electrode form a electrode field to allow the ionizable gas to form plasma a high-voltage amplification coil is disposed between the electrode and power supply part and a needle tube is disposed at a position different from the conduit and is communicated with the plasma generating space to enable the plasma to be erupted through the needle tube to form a needle-shaped plasma. The needle-shaped plasma then can be used to remove infected tissue in the dental pulp, and the plasma can be used to destroy bacteria and microorganism with the polymorphic species therein, so as to achieve the efficacies of debridement, sterilization, and disinfection at the same time as dentist performing the root canal operation.一種電漿根管治療器,包含:一電漿產生空間與一導管相通,該導管可供一可解離氣體進入至該電漿產生空間內;一電極設置於該電漿產生空間周邊處且該電極外包覆介電質;一電源供應部與電極電連結並可使電極形成電場,使該可解離氣體解離形成電漿,且該電極與該電源供應部間設有一高壓放大線圈;及一針管設置於與該導管相異之位置上與該電漿產生空間相通,使電漿可透過該針管噴出形成針型電漿。利用針型電漿移除牙髓內受感染的組織,且針型電漿內的多型態物種對細菌及微生物產生破壞,讓牙醫從事根管治療手術時,同時達到清創與殺菌消毒功效。(A)...電漿(1)...電漿產生空間(2)...導管(3)...可解離氣體(4)...電極(41)...介電質(5)...電源供應部(6)...高壓放大線圈(7)...針管(71)...針型電漿
