Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to bar gauges. Background Technology

[0002] Dental implant technology is an important component of modern dentistry. During dental implant surgery, to ensure accurate placement by directly determining the implant direction based on the bone condition of the implant area, and to allow for clearer visualization of the surgical area during flap surgery, dentists frequently use dental implant guides. For example, patent CN202020163207.1 discloses a dental implant guide that includes a guide cylinder 1, a buccal positioning tip 2, and a handle 3. The guide is marked with the distance H between the horizontal plane where the buccal positioning tip is located and the lower end of the guide cylinder, and the distance D between the central axis of the guide cylinder extending downwards to the horizontal plane where the buccal positioning tip is located. Figure 1 Medical devices inevitably experience bumps or drops during daily use and sterilization. Dentists need to measure the helix height (H) and depth (D) to determine the accuracy of the buccal positioning tip's position and angle, and whether the implant guide needs calibration or repair. Currently, dentists typically use gauges to measure H and D, such as the gauge structure mentioned in application number 202421435480X. Figure 2The system includes a measuring rod, gauge dials, and a base. The measuring rod has several graduations on its outer wall. The base is fixed to the measuring rod, and one or more gauge dials are fixed to the measuring rod. The gauge dials can be evenly distributed on one side of the base or on both sides of the base. Each gauge dial is a circular platform with a shared central axis with the measuring rod. The radius of the gauge dial is smaller than the radius of the base, and the radii of each gauge dial are not equal. The radius value of each gauge dial is marked. Gauge dials closer to the base have larger radii, and those farther from the base have progressively smaller outer diameters. The spacing between adjacent graduations on the measuring rod is equal, and the thickness of each gauge dial is the same, with the same spacing between each adjacent graduation. For ease of description, the measurement method assumes that the distance D between the central axis of the guide mechanism marked on the dental implant guide and the horizontal plane where the buccal positioning tip is located is divided into three dimensions: 3mm, 4mm, and 5mm. The distance H between the horizontal plane where the buccal positioning tip is located and the lower end of the guide mechanism is divided into two dimensions: 8mm and 10mm. Different combinations of H and D result in six instruments of different sizes. For example, an instrument with D of 4mm and H of 10mm can be labeled as D4H10. Corresponding to the above size range of the dental implant guide, the spacing between the graduations on the measuring rod can be 2mm, and the thickness of the measuring disc can be 2mm. The measuring rod has three measuring discs with radii R of 3mm, 4mm, and 5mm, respectively, labeled as R3, R4, and R5. The accuracy of the three-dimensional spatial relationship between the buccal positioning tip and the guide mechanism of the D4H10 model dental implant guide is verified. It is necessary to measure whether the distance between the horizontal plane where the buccal positioning tip is located and the lower end of the guide mechanism is 10mm, and whether the distance between the central axis of the guide mechanism extending downwards to the horizontal plane where the buccal positioning tip is located is 4mm. The specific steps for testing the quality of the dental implant guide are as follows: Figure 3 As shown: (1) The measuring rod of the bar gauge fits tightly with the guiding mechanism of the dental implant guide. The measuring rod can be tightly inserted into the guiding mechanism. When the measuring rod is inserted into the guiding mechanism, the central axis of the measuring rod coincides with the central axis of the guiding mechanism of the dental implant guide; (2) Insert the measuring rod of the dental implant guide bar gauge into the guiding mechanism from the lower end of the guiding mechanism of the instrument. If the buccal positioning tip touches the outer edge of the R4 gauge plate, then D = 4mm. At this time, the D of the instrument is consistent with the mark; if the buccal positioning tip falls on the R4 gauge plate... The markings on the gauge indicate that D is less than 4mm, which is unqualified; if there is a distance between the cheek-side positioning tip and the outer edge of the R4 gauge, it is unqualified; (3) when the D of the instrument matches the marking, the bottom of its cheek-side positioning tip will contact the upper surface of the R5 gauge. If the third scale line of the measuring rod at the bottom of the guide mechanism is flush with the figure, and H is equal to the distance between the three scale lines plus the thickness of the two gauges, which is 10mm, it means that the H of the instrument matches the marking; if the bottom of the guide mechanism does not correspond to the third scale line, it is unqualified. Only when the measured D and H are consistent with the markings on the instrument is it qualified. Otherwise, it is unqualified. Its measurement method is too complicated, and the measurement results have a slight error. Summary of the Invention

[0003] In response to the aforementioned technical problems, this utility model provides a bar gauge that can quickly measure various models of dental implant guides. The measurement operation is simple and the measurement accuracy is high.

[0004] To achieve the above objectives, the technical means adopted by this utility model are as follows:

[0005] A gauge bar consists of a measuring rod, gauge discs, and a base. The measuring rod has several graduations on its outer wall. The base is fixed to the measuring rod, and several gauge discs are mounted on the base. Each gauge disc has a different radius, and the horizontal distance between each point on the outer edge of each gauge disc and the outer diameter of the measuring rod is equal.

[0006] Preferably, the guide plate can be a fan-shaped platform.

[0007] This utility model has the following advantages:

[0008] Because dental implant guides come in various sizes, the distance H between the horizontal plane where the buccal positioning tip is located and the lower end of the guide tube varies. Multiple graduations are provided on the measuring rod; the distance between each graduation and the base plate represents the distance H between the horizontal plane where the buccal positioning tip is located and the lower end of the guide tube for each model. The distance D between the central axis of the guide tube extending downwards to the horizontal plane where the buccal positioning tip is located also varies. The radius of each gauge plate represents the distance D between the central axis of the guide tube extending downwards to the horizontal plane where the buccal positioning tip is located for each model. Measurement is simple and yields accurate results. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0018] like Figure 4 and 5 As shown, the gauge bar includes a measuring rod, a gauge plate, and a base. The measuring rod 4 has several graduations 5 on its outer wall. The base plate 6 is fixed on the measuring rod. Several gauge plates 7 with fan-shaped platforms are provided on the base plate. The radius of each gauge plate is different, and the horizontal distance between each point on the outer edge of each gauge plate and the outer diameter of the measuring rod is equal.

[0019] When using this invention, the steps for testing the quality of the dental implant guide are as follows: The measuring rod of the guide bar is tightly fitted with the guide tube of the dental implant guide, allowing the measuring rod to be firmly inserted into the guide tube. When the measuring rod is inserted into the guide tube, its central axis coincides with the central axis of the guide tube of the dental implant guide. During downward movement, if the bottom of the buccal positioning tip can only touch the larger guide plate and cannot reach the base plate of the guide bar, the guide bar can be rotated to allow the buccal positioning tip of the dental implant guide to move downward along the smaller radius guide plate until it touches the base plate. Check if the scale line on the measuring rod corresponding to the bottom of the guide tube is the H value marked on the dental implant guide. If it is, it is qualified; otherwise, the dental implant guide is unqualified. Check if the tip of the buccal abutment can touch the outer edge of the guide plate with a radius of D. If it can touch, it is qualified; if it cannot, it is unqualified. See [link to relevant documentation]. Figure 6 .
