Embodiment approach 1

[0028] The root canal treatment device according to Embodiment 1 of the present invention is a root canal treatment device including a root canal enlargement and root canal length measurement system equipped with a head. However, the root canal treatment device described below is an example, and it can also be applied to a dental treatment device having the same configuration.

[0029] The endodontic treatment apparatus according to Embodiment 1 performs root canal enlargement by cutting the root canal wall of the tooth by rotating a cutting tool (file, reamer, etc.) held in the head portion by a motor. In addition, the endodontic treatment apparatus can electrically detect the position of the distal end of the cutting tool in the root canal by using the cutting tool as the measurement electrode. Therefore, the endodontic treatment apparatus can control the driving of the cutting tool according to the position of the tip of the cutting tool. Here, the rotation in the directio...

Embodiment approach 2

[0072] In the root canal treatment device according to Embodiment 1, when the position of the tip of the cutting tool 5 reaches the predetermined setting position 50b, the cutting tool 5 is reversed by a predetermined setting angle (for example, 180 degrees) and stopped. rotate. However, in the endodontic treatment apparatus according to Embodiment 2 of the present invention, control is performed to detect the load applied to the cutting tool 5 after the cutting tool 5 is driven in reverse at a set angle. In addition, the configuration of the endodontic treatment device according to Embodiment 2 has different control contents, but it is basically the same as the configuration of the endodontic treatment device according to Embodiment 1, so detailed description is omitted, and only different control contents are described. illustrate. In addition, the reference numerals used in the configuration of the endodontic treatment device according to the first embodiment are similarly...

Embodiment approach 3

[0081] The endodontic treatment apparatus 100 according to the second embodiment executes the following control: after the position of the tip of the cutting tool 5 reaches the predetermined set position 50b and the cutting tool 5 is driven in reverse to set the angle, it detects that Tool 5 load. However, in the endodontic treatment apparatus according to Embodiment 3 of the present invention, control is performed to detect the load applied to the cutting tool 5 when the cutting tool 5 is driven to rotate in the normal direction. In addition, the configuration of the endodontic treatment device according to Embodiment 3 has different control contents, but it is basically the same as the configuration of the endodontic treatment device according to Embodiment 1, so detailed descriptions are omitted, and only different control contents are described. illustrate. In addition, the reference numerals used in the configuration of the endodontic treatment device according to the fi...

Abstract

Provided is a root canal treatment device which, when the rotation of a cutting tool is stopped after the leading end of the cutting tool reaches a preset position, prevents shavings from being pushed back into a root canal while releasing a blade of the cutting tool which has cut into the wall of the root canal. This root canal treatment device is provided with: a hand piece, on a head part, for holding a cutting tool in a drivable manner; a motor driver and a micromotor for driving the cutting tool; a root canal length measurement circuit; and a control unit. The root canal length measurement circuit electrically detects the position of the leading end of the cutting tool in a root canal using the cutting tool as measurement electrodes. When the position of the leading end of the cutting tool detected by the root canal length measurement circuit reaches a preset position, the control unit reverses the cutting tool by a preset angle (180 degrees) and then drives the cutting tool to stop the rotation thereof.

Description

technical field [0001] The present invention relates to a root canal treatment device for treating a root canal of a tooth. Background technique [0002] In a conventional root canal treatment device, a root canal is cut by rotating a cutting tool (hereinafter also referred to as a file) having a helically formed blade. Furthermore, in the root canal treatment device described in Japanese Patent Application Laid-Open No. 09-038108 (Patent Document 1), when the file is rotated in the forward rotation direction to cut the root canal, when the file reaches a predetermined set position (root point position), the file is controlled to rotate in the reverse direction or to stop the rotation. In addition, in the root canal treatment device described in Patent Document 1, when the load (for example, torque) applied to the file is greater than the set load, the file is rotated in the reverse direction or stopped in order to avoid damage to the file. Rotational controls. [0003] F...
