Description

Technical Field

[0001] This application belongs to the field of oral medical device technology, specifically relating to a periodontal probe. Background Technology

[0002] A periodontal probe is a specialized tool used in dental examinations to measure the depth of periodontal pockets. During use, the probe tip is inserted into the periodontal pocket (the space between the tooth and gum). The depth of insertion when the tip reaches the bottom of the pocket (where the gum and tooth are joined) is the periodontal pocket depth. Periodontal probes typically have graduations on their tips, allowing operators to assess pocket depth. However, current graduation designs are flawed and hinder accurate pocket depth assessment. Utility Model Content

[0003] This application discloses a periodontal probe that helps users determine the insertion depth of a needle tip during the detection of periodontal pocket depth.

[0004] The periodontal probe includes: Handle; and A probe is attached to a handle. The end of the probe away from the handle is a probe tip for detection. The probe tip includes multiple segments, adjacent segments are different colors, and at least one segment is an oxidized segment. The oxidized segment includes a probe body, an anodic oxide film, a coloring layer, and a sealing layer. The anodic oxide film surrounds and covers the surface of the probe body and has multiple pores. The coloring layer is located in the pores. The sealing layer surrounds and covers the anodic oxide film and the coloring layer on the side away from the probe body. The oxidized segment presents a preset color through the coloring layer.

[0005] In one alternative implementation, the plurality of segments include a first segment, a second segment, and a third segment, wherein the distances from the first segment, the second segment, and the third segment to the tip of the needle increase sequentially, and the colors presented are all different.

[0006] In one alternative implementation, the first segment, the second segment, and the third segment are all oxidized segments.

[0007] In one optional implementation, the first segment is an oxidized segment, and the second and third segments are both non-oxidized segments.

[0008] In one optional embodiment, both the second segment and the third segment include a probe body and a coloring layer, wherein the coloring layer is formed by any one of the following processes: spraying, screen printing, UV printing, hand-painting, or coating.

[0009] In one alternative implementation, the colors of the first segment, the second segment, and the third segment are green, yellow, and red, respectively.

[0010] In one alternative implementation, the length of each segment is 2mm-5mm.

[0011] In one alternative embodiment, the thickness of the anodic oxide film is less than or equal to 5 μm.

[0012] In one alternative implementation, the handle and the probe are detachably connected.

[0013] In one alternative implementation, the handle is provided with an anti-slip structure.

[0014] Compared with the prior art, the beneficial effects of this application are as follows: In the periodontal probe provided in this application, the probe tip has multiple segments, and adjacent segments are different colors. This facilitates the determination of the insertion depth of the probe tip during the detection of periodontal pocket depth. Furthermore, at least one of the multiple segments is an oxidized segment. The coloring layer of this oxidized segment is located within the pores of the anodic oxide film and is covered by a sealing layer. This makes the coloring layer resistant to fading and discoloration. In other words, even with long-term use, the oxidized segment can maintain its original color, thus avoiding interference with the operator's judgment of the probe tip insertion depth due to fading or discoloration. In short, the oxidized segment can maintain its original color for a long time, which also helps in determining the insertion depth of the probe tip during the detection of periodontal pocket depth.

[0027] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0028] Please refer to Figures 1 to 2 This application provides a periodontal probe 1, which can be used to detect the depth of periodontal pockets. The periodontal probe 1 includes a handle 10 and a probe 20.

[0029] The handle 10 is a grip for holding, and its design is ergonomic for easy holding and operation. The handle 10 has an anti-slip structure to prevent slippage and interference with use. The anti-slip structure can be a raised texture, dispersed protrusions, or a non-cylindrical contour. Raised textures are ridges protruding from the handle surface, which can be horizontal or vertical, spiral, etc. Dispersed protrusions are multiple raised dots on the handle surface, which can be arranged regularly (e.g., in a grid or petal shape) or randomly. A non-cylindrical contour means the handle 10's cross-section is not circular; it can be polygonal, elliptical, triangular, etc. Using a non-cylindrical contour prevents slippage during rotation.

[0030] The probe 20 is connected to the handle 10, and the end of the probe 20 away from the handle 10 is a probe tip 21 for detection. The probe tip 21 includes multiple segments 210, which are arranged sequentially along a preset direction F, i.e., the length direction of the probe tip 21. Adjacent segments 210 are different colors, which makes it easier for the operator to distinguish the insertion depth of the probe tip 21. The color of each segment 210 can be, but is not limited to, black, red, yellow, green, blue, etc.

[0031] At least one of the segments 210 is an oxidized segment, that is, all segments 210 may be oxidized segments, or only some segments 210 may be oxidized segments, while the other part of segments 210 may be non-oxidized segments.

[0032] Please refer to Figure 3The oxidation section includes a probe body X1, an anodic oxide film layer X2, a coloring layer X3, and a sealing layer X4. The probe body X1 is columnar. The anodic oxide film layer X2 surrounds and covers the surface of the probe body X1. The anodic oxide film layer X2 has multiple pores X21, the coloring layer X3 is located within the pores X21, and the sealing layer X4 surrounds and covers the side of the anodic oxide film layer X2 and the coloring layer X3 opposite to the probe body X1. The oxidation section exhibits a preset color through the coloring layer X3. The probe body X1 is the main structure of the probe 20 and serves as the substrate for forming the anodic oxide film layer X2. The material of the probe body X1 can be, but is not limited to, martensitic stainless steel, austenitic stainless steel, titanium alloy, nickel-titanium alloy, molybdenum alloy, aluminum alloy, cobalt-chromium-tungsten alloy, tungsten carbide cobalt-based alloy, tungsten carbide nickel-based alloy, etc.

[0033] The fabrication process for the oxidation zone can be as follows: First, the probe body X1 is anodized, resulting in an anodized film layer X2 with a porous structure X21 on its surface. Then, a coloring process is performed, allowing dye to penetrate the pores X21 of the anodized film layer X2 to form a coloring layer X3. Finally, a sealing process is performed to form a sealing layer X4. The sealing layer X4 seals the pores X21 of the anodized film layer X2, firmly locking the coloring layer X3 within the pores and preventing fading and discoloration. This sealing layer X4 also comprehensively improves the hardness, wear resistance, and corrosion resistance of the oxidation zone. This fabrication process will be referred to as the anodizing coloring process.

[0034] In related technologies, each section 210 is colored using spraying or printing processes, but the colored layer X3 formed by these processes is prone to wear or corrosion. In this application, the anodic oxide film layer X2 is generated by the probe body X1 and is not physically attached, so there is no risk of peeling; secondly, the covering layer X4 can improve hardness, wear resistance and corrosion resistance, so the colored layer X3 can stably maintain its original color, and the colored layer X3 can be selected according to the required color.

[0035] In summary, in the periodontal probe 1 provided in this application, the tip 21 of the probe 20 is provided with multiple segments 210, and adjacent segments 210 have different colors. This facilitates the determination of the insertion depth of the tip 21 during the detection of periodontal pocket depth. In addition, at least one of the multiple segments 210 is an oxidized segment. The coloring layer X3 of the oxidized segment is located in the pores X21 of the anodic oxide film layer X2 and is covered by the sealing layer X4. This makes the coloring layer X3 less prone to fading and discoloration. In other words, even with long-term use, the oxidized segment can maintain its original color, thereby avoiding interference with the operator's judgment of the insertion depth of the tip 21 due to fading or discoloration. That is, the oxidized segment can maintain its original color for a long time, which also helps to determine the insertion depth of the tip 21 during the detection of periodontal pocket depth.

[0036] The number of segments 210 provided on the needle tip 21 can be 2, 3, 4, etc. The following description uses the example of the needle tip 21 having three segments 210.

[0037] Please refer to Figure 2 Optionally, the plurality of segments 210 include a first segment 211, a second segment 212, and a third segment 213. The distances from the first segment 211, the second segment 212, and the third segment 213 to the needle tip surface M21 increase sequentially, and the colors they present are different from each other. That is, the first segment 211, the second segment 212, and the third segment 213 present three different colors, which makes the distinction between the three segments 210 more obvious and makes it easier for the operator to judge the insertion depth of the needle tip 21 during the detection of periodontal pocket depth.

[0038] The first segment 211, the second segment 212, and the third segment 213 can be green, yellow, red, blue, black, white, orange, etc. For example, the colors of the first segment 211, the second segment 212, and the third segment 213 could be green, yellow, and red, respectively, meaning that the color layer X3 of the first segment 211 is green, the color layer X3 of the second segment 212 is yellow, and the color layer X3 of the third segment 213 is red. It is understandable that the human eye is highly sensitive to green, yellow, and red, allowing the operator to judge the needle insertion depth based on the color boundaries. As another example, the colors of the first segment 211, the second segment 212, and the third segment 213 could be black, white, and blue, respectively, meaning that the color layer X3 of the first segment 211 is black, the color layer X3 of the second segment 212 is white, and the color layer X3 of the third segment 213 is blue.

[0039] Example explanation: Assume that the first segment 211 is green, the second segment 212 is yellow, and the third segment 213 is red. During the process of probing the depth of periodontal pockets, if the gingival margin corresponds to the green area, it indicates that the gingiva is normal. If the gingival margin corresponds to the yellow area, it indicates that there is moderate or mild periodontitis. If the gingival margin corresponds to the red area, it indicates that there is moderate or severe periodontitis.

[0040] Please refer to Figure 4 In one embodiment, the first segment 211, the second segment 212, and the third segment 213 are all oxidized segments. That is to say, the coloring layer X3 of the three segments 210 is not easy to fade or change color. Even with long-term use, it can maintain its original color, thereby avoiding interference with the operator's judgment of the insertion depth of the needle tip 21 due to fading or discoloration.

[0041] Please refer to Figure 5 In another embodiment, the first segment 211 is an oxidized segment, and the second segment 212 and the third segment 213 are both non-oxidized segments. The third segment 213 includes a probe body X1 and a coloring layer X3, wherein the coloring layer X3 is formed by any one of the following processes: spraying, printing (screen printing, UV printing), hand-painting, or coating.

[0042] Understandably, because the second segment 212 and the third segment 213 are far from the tip surface M21 of the needle, they are not frequently used in probing the depth of periodontal pockets. That is, the first segment 211 experiences more friction, and only a small number of patients have periodontal pockets deep enough to reach the second segment 212 and the third segment 213. Even if the coloring layer X3 of the second segment 212 and the third segment 213 is formed by spraying, printing, hand-painting, or coating, the probability of wear or corrosion will be reduced. In addition, the anodizing process has certain limitations on the type of substrate and color, while spraying, printing, hand-painting, and coating do not have these limitations. Therefore, in this embodiment, the first segment 211 is an oxidized segment (i.e., anodizing is used for coloring), which has better color stability. The second segment 212 and the third segment 213 are non-oxidized segments, formed by spraying, printing, hand-painting, or coating, which offer greater freedom in color selection.

[0043] Please refer to Figure 3 Optionally, the length H1 of each segment 210 in the preset direction F can be 2mm-5mm, specifically 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc. It should be noted that the length of each segment 210 can be the same or different.

[0044] In one embodiment, the length H1 of each segment 210 is 3 mm. For example, the length H1 of the first segment 211, the second segment 212, and the third segment 213 is 3 mm, and the total length of the three segments 210 is 9 mm.

[0045] In another embodiment, the length H1 of each segment 210 is 4 mm. For example, the length H1 of the first segment 211, the second segment 212, and the third segment 213 mentioned above is 4 mm, and the total length of the three segments 210 is 12 mm.

[0046] In another embodiment, the length H1 of each segment 210 is 5mm. For example, the length H1 of the first segment 211, the second segment 212, and the third segment 213 mentioned above is 5mm, and the total length of the three segments 210 is 15mm.

[0047] In another embodiment, the length H1 of each segment 210 is not all the same. For example, the lengths H1 of the first segment 211, the second segment 212, and the third segment 213 are 3mm, 3mm, and 2mm, respectively. That is, the length H1 of the first segment 211 is 3mm, the length H1 of the second segment 212 is 3mm, and the length H1 of the third segment 213 is 2mm.

[0048] In another embodiment, the length H1 of each segment 210 is different from each other. For example, the lengths H1 of the first segment 211, the second segment 212, and the third segment 213 are 3mm, 4mm, and 5mm, respectively. That is, the length H1 of the first segment 211 is 3mm, the length H1 of the second segment 212 is 4mm, and the length H1 of the third segment 213 is 5mm.

[0049] Please refer to Figure 3 Optionally, the thickness H2 of the anodic oxide film layer X2 can be less than or equal to 5 μm. Specific values ​​for the thickness H2 can be 1.5 μm, 2 μm, 2.6 μm, 3 μm, 3.3 μm, 4 μm, 4.62 μm, 5 μm, etc.

[0050] Optionally, the handle 10 and the probe 20 are detachably connected. The detachable connection can be a threaded connection, a magnetic connection, a screw connection, etc., facilitating the replacement of different probe 20 models. Specifically, a threaded connection means that either the handle 10 or the probe 20 has an internal thread, and the other has an external thread, and the two are screwed together by the internal and external threads. A magnetic connection means that either the handle 10 or the probe 20 has a magnet, and the other has a magnetic object that can be attracted by the magnet, and the two are magnetically attracted together by the magnet and the magnetic object. A screw connection means that the handle 10 and the probe 20 are connected together by a screw.

It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.
