根管治疗是口腔科一项经常性的工作。多年来,我院一直是用根管充填针一点一点地送入根管内部进行充填,手工操作很不方便,占用时间长,工作效率低。为解决这个问题,我们试制了一种微型根管充填机,现介绍如下: 一、根管充填机的原理及构造这种充填机,是根据蜂鸣器电磁铁吸引弹簧片产生高频率机械性震荡的原理试制的。主要是用连接杆延长弹簧片并带动充填针,使根管糊剂在充填针高频率震荡和引导下,沿着根管壁流入内部,达到充填根管的目的。这种装置主要由蜂鸣器、微动开关、连接杆、充填针、外接电源(6V直流或3～6V变压交流)组成。具体线路如附图。体积约6×4×2立方厘米,重量约90克左右。
Root canal therapy is a regular work in dentistry. Over the years, our hospital has been filled with root canal filling needle little by little into the root canal filling, manual operation is very convenient, take a long time, low efficiency. To solve this problem, we trial a miniature root canal filling machine, are described as follows: First, the principle and structure of root canal filling machine This filling machine is based on the buzzer magnet to attract the spring to produce high-frequency mechanical The principle of shock trial. Mainly use the connecting rod to extend the spring piece and drive the filling needle so that the root canal paste flows into the interior along the root canal wall under the high frequency concussion and guidance of the filling needle to achieve the purpose of filling the root canal. This device mainly consists of buzzer, micro switch, connecting rod, filling needle, external power supply (6V DC or 3 ~ 6V transformer AC). Specific lines as the photo. Volume of about 6 × 4 × 2 cubic centimeters, weighing about 90 grams.
