Device for heating and filling tooth in dental canal

Abstract

The invention discloses a device for heating and filling a tooth in a dental canal, which comprises a heating tip, a high-temperature resistant insulation sleeve, a low-impedance inner conductor, a low-impedance outer conductor, a cathode and an anode, wherein the heating tip is made of a high-temperature resistant heating material; the rear of the heating tip is connected with the low-impedance inner conductor and the low-impedance outer conductor which galvanize a high-frequency controllable current at the position of the heating tip, so that a resistor at the position of the heating tip generates a great amount of heat under the action of the current; a layer of high-temperature resistant insulation sleeve is arranged between the low-impedance inner conductor and the low-impedance outer conductor; the low-impedance inner conductor is connected with the anode, while the low-impedance outer conductor is connected with the cathode; and the diameter of the heating tip is 0.1 to 1mm. The temperature of a filling needle used by a process of the invention is easy to control, and the problem that a root tip and a branched canal cannot be completely filled in the canal filling and the problem that a cavity is formed in the canal filling are solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a tooth root canal heating and filling device. Background technique [0002] Currently, there are two options for tooth root canal filling treatment. One is filling with cold gutta-percha, and filling the root canal with a root canal expansion needle. This method is difficult to fill evenly, and the treatment effect is poor. Not in place; another filling with heated gutta-percha, the traditional heating gutta-percha filling method: heat the vertical pressurizer with an alcohol lamp outside the oral cavity in advance, after the vertical pressurizer is hot, quickly put the root canal into the tooth, pressurize A gutta-percha that has been implanted in the root canal to complete the root canal filling. Because the temperature on the vertical presser passes through secondary transmission, the temperature of the tip of the vertical presser is not easy to control. It is completely based...

[0002] Currently, there are two options for tooth root canal filling treatment. One is filling with cold gutta-percha, and filling the root canal with a root canal expansion needle. This method is difficult to fill evenly, and the treatment effect is poor. Not in place; another filling with heated gutta-percha, the traditional heating gutta-percha filling method: heat the vertical pressurizer with an alcohol lamp outside the oral cavity in advance, after the vertical pressurizer is hot, quickly put the root canal into the tooth, pressurize A gutta-percha that has been implanted in the root canal to complete the root canal filling

Because the temperature on the vertical presser passes through secondary transmission, the temperature of the tip of the vertical presser is not easy to control. It is completely based on the doctor's feeling and experience. If the temperature is too high, the gutta-percha will be carbonized; if the temperature is too low, the gutta-percha will fill the root canal of the side branches Not in place, resulting in the failure of root canal treatment
