Description

Technical Field

[0001] The utility model relates to the technical field of medical device measurement, in particular to a rod gauge. Background Art

[0002] Oral implant technology is an important part of modern stomatology. Oral implant guides are tools frequently used by dentists. For example, patent CN202020163207.1 discloses an oral implant guide, which includes a body, a guide mechanism, a buccal positioning tip, and a handle. Two values, D and H, are marked on the oral implant guide. D represents the distance between the central axis of the guide mechanism extending downward to the horizontal plane where the tip of the buccal positioning tip is located, and H represents the distance between the horizontal plane where the tip of the buccal positioning tip is located and the lower end of the guide mechanism. Figure 1 . Doctors can obtain the three-dimensional relationship value between the implant and the buccal bone wall by measuring the patient's jaw CT image, and then select the oral implant guide according to the D and H marked on the instrument. It is inevitable that the instrument will be bumped or dropped during daily use and disinfection. The buccal positioning tip of the oral implant guide is relatively prominent in the overall appearance of the instrument and is relatively slender. It is easy to bend and deform due to accidents, resulting in changes in the spatial three-dimensional relationship between it and the guide mechanism, making the actual H and D of the instrument inconsistent with the instrument's markings. Therefore, dentists need to frequently measure the actual H and D of the instrument to confirm whether they are consistent with the markings. If they are inconsistent, the doctor needs to replace the new instrument to avoid misleading the doctor. Due to the irregular structure of the oral implant guide, there is currently no tool that can accurately measure its D and H. Dentists cannot accurately measure it with a ruler, resulting in the inability to determine whether the three-dimensional relationship between its buccal positioning tip and the guide mechanism is consistent with the markings. Utility Model Content

[0003] Based on the technical problems raised above, the utility model provides a rod gauge, which can measure the distance D between the central axis of the guide mechanism of the oral implant guide extending downward to the horizontal plane where the tip of the buccal positioning tip is located, and the distance H between the horizontal plane where the tip of the buccal positioning tip is located and the lower end of the guide mechanism, to measure whether they are consistent with the marked ones, with accurate measurement and easy use.

[0004] In order to achieve the above purpose, the technical means adopted by the utility model are as follows:

[0005] A rod gauge includes a plug measuring rod, a gauge plate and a base plate. There are several scales on the outer wall of the plug measuring rod. The base plate is fixed on the plug measuring rod. One or several gauge plates are fixed on the plug measuring rod. Several gauge plates can be arranged on one side of the base plate or on both sides of the base plate. The gauge plate is a circular platform. The gauge plate and the plug measuring rod share a central axis. The radius of the gauge plate is smaller than the radius of the base plate, and the radii of each gauge plate are not equal. The radius value of the gauge plate is marked on each gauge plate. The radius of the gauge plate close to the base plate is large, and the outer diameter of the gauge plate away from the base plate becomes smaller successively. The spacing between adjacent scale lines on the plug measuring rod is equal, and the thickness of each gauge plate is the same and the spacing between adjacent scale lines is the same.

[0006] The utility model has the following advantages:

[0007] (1) It can measure the distance D between the central axis of the guide mechanism of the oral implant guide and the horizontal plane where the buccal positioning tip is located, and the distance H between the horizontal plane where the buccal positioning tip is located and the lower end of the guide mechanism, and measure whether they are consistent with the marked ones.

[0014] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] Example 1

[0016] like Figure 2 As shown, a rod gauge includes a plug rod, a gauge plate and a chassis. There are several scales 5 on the outer wall of the plug rod 4, a chassis 6 is fixed on the plug rod, and several gauge plates 7 are fixed on the plug rod, and several gauge plates are arranged on both sides of the chassis. The gauge plate is a circular platform, the gauge plate and the plug rod share a central axis, the radius of the gauge plate is smaller than the radius of the chassis, and the radius of each gauge plate is not equal, and the radius value of the gauge plate is marked on each gauge plate. The radius of the gauge plate close to the chassis is large, and the outer diameter of the gauge plate away from the chassis becomes smaller successively. The spacing between adjacent scale lines on the plug rod is equal, and the thickness of each gauge plate is the same and the spacing between adjacent scale lines is the same.

[0017] It should be noted that a plurality of gauge disks may be arranged on one side of the plug measuring rod, or there may be only one gauge disk.

[0018] When the utility model is in use, for the sake of convenience of description, it is assumed that the distance D between the central axis of the guide mechanism marked on the oral implant guide and extending downward to the horizontal plane where the tip of the buccal positioning tip is located is divided into three sizes of 3mm, 4mm, and 5mm, and the distance H between the horizontal plane where the tip of the buccal positioning tip is located and the lower end of the guide mechanism is divided into two sizes of 8mm and 10mm. Different H and D are combined to form six instruments of different sizes. The instrument identification method, such as one instrument with D of 4mm and H of 10mm, can be identified as D4H10.

[0019] Corresponding to the size range of the oral implant guide above, the spacing of the scale lines of the plug rod on the rod gauge can be 2mm, and the thickness of the gauge disc can be 2mm. There are three gauge discs on the plug rod, and the radius R is 3mm, 4mm, and 5mm respectively, which are recorded as R3, R4, and R5 gauge discs.

[0020] Check whether the three-dimensional spatial relationship between the buccal positioning tip and the guide mechanism of the D4H10 oral implant guide is accurate. It is only 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 10 mm, and whether the distance between the central axis of the guide mechanism extending downward to the horizontal plane where the buccal positioning tip is located is 4 mm.

[0021] The specific steps for testing whether the oral implant guide is qualified are as follows: Figure 3 As shown:

[0022] (1) The plugging rod of the rod gauge is tightly matched with the guide mechanism of the oral implant guide, and the plugging rod can be tightly inserted into the guide mechanism. When the plugging rod is inserted into the guide mechanism, the central axis of the plugging rod coincides with the central axis of the guide mechanism of the oral implant guide.

[0023] (2) Insert the measuring rod of the oral implant guide rod gauge from the lower end of the guide mechanism of the instrument into the guide mechanism. If the buccal positioning tip touches the outer edge of the R4 gauge disk, D = 4 mm. At this time, the D of the instrument is consistent with the mark; if the buccal positioning tip falls on the R4 gauge disk, it means that D is less than 4 mm and it is unqualified; if there is a distance between the buccal positioning tip and the outer edge of the R4 gauge disk, it is unqualified.

[0024] (3) When the D of the device matches the mark, the bottom of its buccal positioning tip will contact the upper surface of the R5 gauge disk. If the bottom of the guide mechanism is flush with the third scale line of the plug rod as shown in the figure, H is equal to the distance between the three scale lines plus the thickness of the two gauge disks, which is 10mm, indicating that the H of the device matches the mark; if the bottom of the guide mechanism does not correspond to the third scale line at this time, it is unqualified.

[0025] Only when the measured D and H are consistent with the device markings, it is qualified. Otherwise, it is unqualified.
