Title:
HANDPIECE HAVING ROOT CANAL LENGTH MEASUREMENT FUNCTION
Document Type and Number:
WIPO Patent Application WO/2023/074977
Kind Code:
A1
Abstract:
The present invention relates to a handpiece having a root canal length measurement function such that a practitioner can identify the result of measuring the length of a root canal by using a change in color of an LED light source. A handpiece having a root canal length measurement function according to an embodiment of the present invention may comprise: an angle having a part made of a diffusion material for diffusing LED light from the LED light source, the part comprising one side provided with a root canal treatment pile for removing dental pulp inside the root canal and for expanding the root canal; a lip hook provided such that same can be cradled on the subject's lips; a body portion electrically connected to the pile through a first terminal connector, into which a first terminal provided on the other side of the angle is to be inserted, and electrically connected to the lip hook through a second terminal connector, into which a second terminal of the lip hook is to be inserted; and an LED light source for emitting LED light from one end of the body portion. The body portion may comprise: multiple connectors for electrically connecting a battery, the LED light source, the pile, and the lip hook; and a control module for controlling operations of the battery such that the color of LED light emitted by the LED light source changes according to position information and length information of a dental root end, which are acquired by measuring an impedance value that varies as the pile approach from the tooth surface to the dental root end.
