Abstract
A cordless complex root canal plugger for dental clinics is disclosed. The root canal plugger includes a battery charger; a pen-type vertical spreader having a rechargeable battery unit and a control unit therein; and a gun-type injection device having both a rechargeable battery unit and a control unit therein. The battery charger, the pen-type vertical spreader and the gun-type injection device are provided as a group of complementary products. The cordless complex root canal plugger allows an endodontist to move freely in a dental clinic while executing a root canal plugging procedure using the cordless complex root canal plugger during nerve treatment. Thus, the endodontist can more easily, rapidly and precisely pack a root canal with a filler material and, therefore, the cordless complex root canal plugger induces en-dodontists to buy it.
