Embodiment approach 1

[0034] figure 1 It is a schematic diagram showing the configuration of the endodontic treatment device 100 according to the first embodiment. figure 2 It is a block diagram showing the functional configuration of the root canal treatment device according to the first embodiment. In addition, the dental treatment device according to Embodiment 1 will be described as an endodontic treatment device 100 including systems such as root canal enlargement and root canal length measurement in the handpiece 1 for dental endodontic treatment. However, the dental treatment device according to the present invention is not limited to the root canal treatment device 100, and can be applied to a dental treatment device having the same structure.

[0035] figure 1 The illustrated endodontic treatment device 100 includes a handpiece 1 for dental endodontic treatment, a motor unit 6 , and a control box 9 inside the handpiece 1 . which is, figure 1 The root canal treatment device 100 shown i...

Embodiment approach 2

[0081] In the root canal treatment device 100 according to Embodiment 1, the two-stage control is switched between the driving of the reverse control 112 and the driving of the fail-safe control 113 based on the positional relationship between the position of the tip of the cutting tool 5 and the reference position. explained. However, it is not limited thereto, and the root canal treatment device 100 may switch between the drive of the reverse control 112 and the drive of the fail-safe control 113 under conditions other than the positional relationship between the position of the tip of the cutting tool 5 and the reference position. stage control. Two-stage control executed in the root canal treatment device according to Embodiment 2 will be described using a flowchart. Figure 9 It is a flowchart for explaining the two-stage control executed in the endodontic treatment device 100 according to the second embodiment. In addition, since the root canal treatment device 100 acc...

Abstract

This dental therapy device comprises: a drive unit that is structured from a micro motor (7) and a motor driver (13), or similar; a control unit (11); and a root canal length measurement circuit (12). The control unit (11) forward-rotationally drives a cutting tool (5), which is retained in a head unit (2), in a direction in which the same cuts a cutting target. When the cutting tool (5) is forward-rotationally driven and the root canal length measurement circuit (12) detects the arrival of a tip of the cutting tool (5) at a reference location, the control unit (11) reverse-rotationally drives the cutting tool (5) in the opposite direction from the forward-rotational driving. When the cutting tool (5) is reverse-rotationally driven and the root canal length measurement circuit (12) detects movement of the tip of the cutting tool (5) in the direction of a root tip location, the control unit (11) performs failsafe control.

Description

technical field [0001] The present invention relates to a dental treatment device provided with a handpiece, and more particularly to a dental treatment device for cutting and enlarging the inner wall of a root canal (hereinafter also simply referred to as a root canal) of a tooth and a driving method thereof. Background technique [0002] In dental treatment, root canal cutting and widening are sometimes performed. In this treatment, a dental treatment device in which a cutting tool called a file or a reamer is attached to the head of a handpiece is used, and the root canal is cut and enlarged by driving the cutting tool. When a dental treatment device drives a cutting tool to cut and expand a root canal, the blade of the cutting tool bites into the wall of the root canal, and in a state where the cutting tool is restrained by the biting portion, the cutting tool is further forcibly rotated to cut the root canal. Tools are sometimes twisted and broken. [0003] In the den...
