Description

[Detailed description of the invention] (a) Field of the invention This invention relates to a device for measuring the body position and visual angle of a dentist, trainee, etc. when performing treatment.

(b) Background of the invention In recent years, dental learning devices for training dentists have been developed.

It has been proven that when performing actual dental treatment, once a patient's oral cavity point is determined, the operator can perform all treatments within a limited range of movement around this oral cavity point.

However, ordinary surgeons have never measured their own range of motion during treatment, and if they perform treatment while maintaining a natural posture, they will naturally be able to stay within the limited range of motion as described above. need to be perceived.

(c) Purpose of the invention The present invention provides a device for dentists, trainees, etc. to measure the range of motion during treatment, and to measure the line connecting the eyes and the patient's oral cavity, which is particularly important, that is, the visual angle. With the goal.

(d) Structure of the device This device has a central pillar on which the oral membrane mold is placed on the upper end of the base, and is movable in an arc on the base around the erected position of the central pillar, and A chair is provided so that its forward and backward position and vertical position can be adjusted, and an arc movement position measuring device is installed to measure the range of arc movement of this chair, and a rear measuring column that is linked to the arc movement of this chair is installed on the rear side of the chair. An elbow position measuring device for measuring the position of the elbow, a shoulder position measuring device for measuring the shoulder position, and a cervical vertebrae measuring device for measuring the position of the cervical vertebrae are installed on the rear measuring column, and the central column is sandwiched between the chairs. A front measurement pillar is installed at the opposite position, and is linked to the arc movement of the chair.The front measurement pillar is equipped with a knee position measurement device to measure the position of the knees, and a hand position measurement device to measure the position of the hands. In addition, a transparent top plate with a mark is placed between the operator's eye position and the oral cavity model, and the viewing angle is adjusted by freely changing the mounting angle of the top plate in the front and back positions and the top and bottom positions. The apparatus is characterized in that it is a dental operator's body position and visual angle measuring apparatus, in which a visual angle measuring apparatus for measuring the position and visual angle of a dental operator is attached to the upper end portion of the central support.

(e) Effects of the invention According to this invention, it is possible to measure the range of motion of the operator during treatment, and when the operator looks at the oral cavity while maintaining a natural posture with the back straight and the eyes straight. This measurement data can be used to find common points with the dental learning device, and it is possible to eliminate learning resistance in dental learning devices that only move within a limited range.

In addition, by making people who are already practicing dentistry aware that all post-treatment procedures are performed within a limited range of visual angles, they can easily re-train with the dental learning device. You can enter smoothly without feeling any resistance.

The dental operator body position and visual angle measuring device 10 configured as described above uses the oral cavity of the oral cavity model 13 as a working point, and measures the movements and visual angles of the entire body of the operator and trainee around this point.

The oral cavity model 13 is set so that the head side is located at the 12 o'clock direction and the foot side is located at the 6 o'clock direction on the clock face.

The operator sits on the chair 20 with his or her back against the back plate 33.
This posture is maintained by setting the vertical height and front/back position so as to be natural with respect to the oral cavity model 13.

Next, the operator creates a treatment posture for the oral cavity model 13, and measures the position and visual angle of each measurement site on the body with respect to this treatment posture.

When the operator moves to create one of the treatment postures described above, the operator moves laterally while sitting on the chair 20. At this time, the chair 20 is the oral cavity model 1
3 is the center, and when the operator reaches a predetermined position, the scale 32 of the base 11 indicates what hour and minute the operator is located.
Measure the position of the caster.

Next, an elbow position measuring device 35, a shoulder position measuring device 36, and a cervical vertebrae measuring device 3 are arranged on the rear measuring column 34.
7. Using the visual angle measurement device 100, the elbow, shoulder, and cervical vertebrae are measured as coordinates of the X, Y, and Z axes, and the visual angle is measured as an angle.

Furthermore, each part of the ankle and knee is measured on the X-axis, Y-axis, and
Measured as a Z-axis coordinate.

In this way, by measuring the position of each measurement site on the body for one treatment posture, performing such measurements for various treatment postures, and summing up these measurement results, the position of each measurement site on the body can be determined. The movement range and visual angle of the object can be measured.

By measuring the movement range and visual angle of the entire body, we found commonalities with dental learning devices.
Learning resistance to the dental learning device can be eliminated, and a training posture can be developed.
