Convenient-to-use root canal apex locator

Abstract

The invention belongs to the field of medical instruments and particularly relates to a convenient-to-use root canal apex locator. The convenient-to-use root canal apex locator comprises a host, wherein a controller and a drive device are arranged in the host; a display screen and a reducing bender are arranged outside the host; the reducing bender is rotationally connected with a root canal file; the drive device drives the root canal file to rotate; a conductive elastic element is clamped between the end surface of the root canal file and the inner side surface of a machine cover; the tail end of the host is connected with a lip hook through a measurement line I; a jack is connected with an input end of the controller; the reducing bender is a metal housing and connected with the input end of the controller through a wire; the controller is used for controlling the length of a display root canal of the display screen; and a silicon rubber case sleeves on the outside of the reducing bender. The convenient-to-use root canal apex locator has the beneficial effects that due to the conductive elastic element, the reducing bender and the root canal file are electrically connected always, the impedance is stable and measurement is accurate; the exposed measurement line does not need to be arranged, signal transmission can be isolated from an oral cavity and measurement is accurate; and an elastic metal clamp does not need to be manually pinched additionally, so that the convenient-to-use root canal apex locator is convenient to use.

Description

Technical field [0001] The invention belongs to the field of medical equipment, and specifically relates to a convenient root canal treatment instrument. Background technique [0002] Root canal treatment is the most commonly used and effective treatment method for endodontic and periapical diseases. The principle of root canal treatment is to remove most of the infections in the root canal through mechanical and chemical methods, and to fill the root canal and seal the crown. To prevent the occurrence of periapical lesions or promote the healing of existing periapical lesions. [0003] In clinical root canal treatment, the measurement of root canal length and root canal enlargement are crucial steps. The measurement of root canal length is most commonly determined by root canal length measuring instrument and X-ray method. When root canal enlargement Commonly used methods of combining mechanical and chemical treatments. In the clinical treatment process, different medical equipm...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the instability of the impedance measured by the root canal file in the prior art, the influence of the exposed measurement line on the measurement accuracy, and the need to manually clamp the elastic metal clip in the middle of the root canal file handle. Inconvenient defect, there is always an electrical connection between the deceleration bender and the root canal file, the impedance is stable, and the measurement is accurate; there is no need to set exposed measurement lines, the signal transmission path can be completely isolated from the patient's mouth, and the measurement is accurate , the effect of root canal treatment is good; it is an easy-to-use root canal treatment instrument that does not need to manually hold the elastic metal clip
