Multi-dimensional mechanical information measurement device for evaluation of root canal shaping ability

Abstract

A multi-dimensional mechanical information measurement device for evaluation of root canal shaping ability comprises a three-dimensional displacement control device, a three-dimensional deflection control device, a six-dimensional force measurement device and an extracted tooth fixing device, wherein the three-dimensional displacement control device comprises an X-axis sliding block, a Z-axis sliding block, a Y-axis mounting base and a Y-axis sliding block, the Y-axis mounting base is fixed on the Z-axis sliding block, and the Y-axis sliding block can slide along the Y-axis mounting base; the three-dimensional deflection control device sequentially comprises a force sensor connector, an X-axis rotary steering engine, an Z-axis angle deflection adjustment steering engine and a Y-axis angle deflection adjustment steering engine in the axial direction of the X axis; the six-dimensional force measurement device sequentially comprises a root canal file and a six-dimensional force sensor fixed on the root canal file in the axial direction of the X axis, and the six-dimensional force sensor is fixedly connected with the force sensor connector; the extracted tooth fixing device comprises an extracted tooth fixedly arranged on the Y-axis sliding block, and the extracted tooth can be matched with the root canal file. The device can simulate root canal preparation operation and acquire multi-dimensional mechanical information in real time.

Description

technical field

[0001] The invention relates to the technical field of root canal forming evaluation, in particular to a multi-dimensional mechanical information measuring device for evaluating root canal forming ability. Background technique

[0002] Modern root canal therapy believes that good root canal preparation is the premise of strict root canal filling and the key to the success of root canal therapy. The main purpose of root canal preparation is to use mechanical removal of infected pulp while forming a root canal shape suitable for filling, and it is required to maintain the original anatomical direction of the root canal as much as possible. Therefore, root canal shaping is the main aspect of root canal preparation.

[0003] The research found that the effect of root canal shaping is mainly related to many factors such as the operator's operation, the characteristics of the root canal file, the output characteristics of the root canal treatment motor, the biolog...
