Description

Technical Field

[0001] This utility model relates to dental root canal treatment instruments, and in particular to a fan-shaped root canal length measurement and recording ruler. Background Technology

[0002] In root canal treatment, the length of the root canal needs to be measured to facilitate subsequent filling. Currently, the measurement is mostly done by inserting a reamer into the root canal. The reamer has a float attached to it to mark the length of the root canal. After it is removed, the length of the reamer is measured with a ruler. When the patient has multiple root canals, the doctor has to remember the length of multiple root canals at the same time or the assistant needs to record them with pen and paper, which is prone to errors or increases the workload of the assistant. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing root canal rulers and provide a fan-shaped root canal length measurement and recording ruler that can measure and record the length of the enlarging needle during root canal treatment.

[0004] The technical solution adopted by this utility model is a fan-shaped root canal length measurement and recording ruler. Its key point is that it is made of several measuring strips hinged together. The measuring strips have length markings in the length direction. Grooves are made along the length direction of the measuring strips, and a sliding ruler that can move along the groove is placed in the groove.

[0005] This invention uses a fan-shaped measuring strip. Because the upper surface of the strip has length markings, each strip is laid out sequentially. When the reamer is inserted into the root canal, a float measures the canal length. The float is then placed against the top of the measuring strip; the position of the reamer tip indicates the root canal length. The vernier is moved to the tip position to record the measurement. The dentist records the reamer measurements sequentially on the measuring strips according to their preferred measurement sequence, eliminating the need for manual recording.

[0006] Further design: The zero line of the measuring bar is located at the top of the measuring bar.

[0007] Further design: The measuring strip is equipped with a fixing point for securing the magnifying needle. This fixing point ensures the magnifying needle remains perpendicular, thus improving measurement accuracy.

[0008] Further design: The fixing point is a hole that matches the buoy, and the zero point of the length indicator is located at the tangent of the lower edge of the hole. The buoy is inserted into the hole, and the magnifying pin is fixed to the upper surface of the measuring strip for measurement, ensuring measurement accuracy.

[0009] Further design: Each measuring strip has two grooves, each intersecting the length marking. This allows one measuring strip to record data from two magnifying pins, reducing the number of measuring strips required.

[0010] Further design: A fixing point for the enlarged pin is made above each groove.

[0011] Further design: The measuring strip has markings indicating the three-dimensional location of the root canal.

[0012] Further design features include a storage box around the measuring strip, with a hinge pin fixed to the box. The measuring strip is then fixed to the hinge pin and unfolds in a fan shape. This allows for easy storage of the measuring strip within the box.

[0013] This invention records the measurement data of the reamer by using a vernier scale on the measuring strip. The arrangement of multiple measuring strips along the fan-shaped structure allows the measurement data of the reamer to be marked in sequence, making it easier for doctors to read the measurement data of each root canal during subsequent treatments and reducing the likelihood of errors.

[0021] The present invention will be further described below with reference to the views. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] Example 1, as Figure 1 , 2 As shown in Figure 3, a fan-shaped root canal length measurement and recording ruler is composed of several measuring strips 2 hinged together. The measuring strips have length markings along their length, with the zero mark located at the top. The measuring strips are longer than 40mm and 3-10mm wide, divided according to the common root canal length range (15-31mm). Each measuring strip has a scale value from 0-40, with a number indicating values ​​ending in 10 (numbers are not shown on all measuring strips in the figure for clarity). There is a line every millimeter, with scale values ​​accurate to 0.5mm. The 0.5mm mark is a colored dot, helping medical personnel to more accurately estimate data down to the millimeter. For clarity, not all 0.5mm marks are shown; only one is depicted for illustration.

[0024] A groove is made along the length of the measuring strip, and a movable vernier scale 4 is placed in the groove. The groove and the vernier scale are structurally compatible, such as a cylindrical groove as shown in the figure, or a traditional dovetail groove. The vernier scale has a long strip at the top and its lower part matches the shape of the groove.

[0025] The measuring strips have markings for the three-dimensional locations of the root canal, which can be marked with colors or text. In the diagram, the six measuring strips correspond to the mesial buccal (MB), distal buccal (DB), mesial lingual (ML), distal lingual (DL), palatal (P), and MB2, respectively.

[0026] A storage box 1 is located outside the measuring strip. A hinge pin is fixed to the storage box, and the measuring strip is fixed to the hinge pin, unfolding in a fan shape. A hinged fixing buckle 3 is located at the top of the storage box. The measuring strip is fixed in the storage box for easy storage.

[0027] Example 2, as Figure 4As shown, each measuring strip has two grooves, each equipped with a vernier. Below each vernier are markings corresponding to the mesial buccal (MB), distal buccal (DB), mesial lingual (ML), distal lingual (DL), palatal (P), and MB2. This allows one measuring strip to record the dimensions of two enlarging needles, reducing the number of measuring strips required. The remaining undescribed parts are the same as in Example 1.

[0028] Example 3, as Figure 5 , 6 As shown, this is an improvement on Example 1. A fixing point for the magnifying needle is made on the measuring strip. The fixing point is a hole 22 that matches the float. Typically, the float is a flat cube, so the hole in this example is a rectangle that matches it. The zero point of the length indicator is located at the tangent of the lower edge of the hole. During measurement, the float of the magnifying needle is fixed in the hole 22 before taking the reading. The magnifying needle is not affected by the user's hand movements, which would cause the float to deviate from the top of the measuring strip, thus affecting the measurement accuracy. Furthermore, after fixing the magnifying needle, there is no need to hold it; the sliding scale can be moved directly by hand to the needle tip position.
