Description

Technical Field

[0001] The utility model relates to the technical field of root canal file measurement, in particular to a root canal file measuring device. Background Art

[0002] The root canal file is an indispensable instrument in the root canal treatment process. Its main function is to clean and shape the root canal for subsequent root canal filling and other operations. There are many types of root canal files, such as K files, H files, etc. Different types of root canal files differ in design and function to adapt to different root canal morphologies and treatment needs. When using a root canal file, it is often necessary to use a measuring ruler to accurately measure the length of the file entering the root canal. The specific measurement method is: after straightening the root canal file, put the positioning ring into the corresponding groove of the measuring ruler, and then the length value can be determined.

[0003] However, it should be noted that the pre-bending direction and angle of the root canal file are not replicable. If it is straightened when measuring the length, it may not be able to reach the working length when entering the root canal again due to the loss of the original pre-bending shape. This will have an adverse effect on the treatment and may even lead to treatment failure. Therefore, when measuring the length of the root canal file, it is not desirable for the root canal file to be straightened, but its original bending state should be maintained as much as possible to ensure that it can accurately reach the corresponding position in the root canal in subsequent operations and achieve a good treatment effect. Therefore, in view of the above phenomenon, a root canal file measuring device is proposed to meet the needs of actual use. Utility Model Content

The front end of the root canal file body 100 after pre-bending is inserted from the top of the mounting seat 1 and enters the interior of the hose 4. The hose 4 has a small wall thickness and is easy to bend. It will bend under the action of the front end of the root canal file body 100. The front end of the root canal file body 100 also contacts the side of the positioning column 6. Under the advancement of the root canal file body 100, the positioning column 6 moves toward the bottom end of the hose 4. After the bottom surface of the positioning ring 101 contacts the top surface of the mounting seat 1, the scale line 5 corresponding to the positioning column 6 is the root canal depth. After the root canal file body 100 is taken out, the front end of the root canal file body 100 can still maintain the pre-bent state, so as to enter the root canal again and reach the working length.
