Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation fixture for assisting in cleaning an intraoral probe plate. Background Technology

[0002] An intraoral detector is a precision device used in the field of oral medicine, primarily for intraoral imaging and diagnosis. It helps dentists observe teeth, gums, and internal oral structures more clearly, with the detector's flat panel playing a key role. As a sophisticated electronic device, the protection and isolation of the detector's circuitry are crucial. During the Parylene coating process, protective adhesives (such as peelable UV adhesive, silicone foam, etc.) are typically used to protect the circuitry from external environmental influences. However, these traditional materials are often encapsulated by Parylene after coating, making them difficult to remove and potentially damaging the product during removal, affecting product quality and production efficiency.

[0003] While materials like peelable UV adhesive and silicone foam offer certain advantages in protective performance, removing them after coating with paraffin has become a technical challenge in the industry. In actual production, the common practice is to hold the intraoral detector plate with two fingers and pry it off with tweezers. This method easily leads to uneven force, causing localized deformation of the intraoral detector plate and affecting product quality and yield. This not only increases the difficulty of the production process but can also damage the product, impacting its final quality and performance. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a fixing fixture for assisting in cleaning the probe plate inside the mouth, so as to solve the problems in the prior art.

[0005] To achieve the above-mentioned and other related objectives, this utility model is obtained through the following technical solution.

[0006] This utility model provides a fixing fixture for assisting in cleaning an intraoral detector plate, including a detachably connected support base and an upper cover plate; the support base is provided with a limiting groove for accommodating the intraoral detector plate; the upper cover plate is provided with a limiting through hole corresponding to the limiting groove, and the upper cover plate is formed with a limiting edge for partially covering the limiting groove, so as to limit the intraoral detector plate within the limiting groove and expose it partially.

[0007] In one embodiment, the detachable connection is a snap-fit ​​and / or a fixed screw connection and / or a hinge.

[0008] In one specific embodiment, the limiting groove extends inward from the side wall of the supporting base.

[0009] In one specific embodiment, the inward extension length is less than the length of the intraoral detector plate, so that the corresponding part of the connecting gold wire of the intraoral detector plate is exposed.

[0010] In one specific embodiment, the upper cover plate has a U-shaped structure, and the open end of the U-shaped structure corresponds to the side wall opening of the limiting groove 11.

[0011] In one specific embodiment, the upper cover plate has two opposing limiting edges, and the ratio of the opening width L1 of the limiting through hole to the opening width L2 of the limiting groove is 0.6 to 0.7.

[0012] In one specific embodiment, the limiting edge is formed on the edge of the upper cover plate near the limiting through hole.

[0013] In one specific embodiment, the depth of the limiting groove is 0.2 to 1 mm greater than the thickness of the plate of the intraoral flat plate detector.

[0014] In one specific embodiment, the limiting edge is a sloped structure.

[0015] In one specific embodiment, the limiting edge is tilted downward at an angle of 15 to 30°.

[0016] In one specific embodiment, the sidewall of the limiting groove is provided with a silicone protective layer.

[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0033] Please see Figures 1 to 4 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0034] like Figures 1-4 As shown, this utility model provides a fixing fixture for assisting in cleaning an intraoral detector plate, including a detachably connected support base 1 and an upper cover plate 2; the support base 1 is provided with a limiting groove 11 for accommodating the intraoral detector plate 3; the upper cover plate 2 is provided with a limiting through hole 21 corresponding to the limiting groove 11, and the upper cover plate 2 is formed with a limiting edge 22 for partially covering the limiting groove 11, so as to limit the intraoral detector plate within the limiting groove 11 and expose it partially.

[0035] The aforementioned fixing fixture uses a top cover plate 2 and a supporting base 1 to jointly fix the intraoral detector plate 3, facilitating the cleaning of the protective adhesive 31 on the upper surface of the intraoral detector plate 3. A knife or tweezers can be used to reach under the protective adhesive 31, gently pry it up, and quickly remove it. Furthermore, this process ensures even force distribution on the intraoral detector plate 3, reducing scrap due to uneven force and improving the yield rate. Therefore, using this fixing fixture not only easily removes the protective adhesive 31 from the upper surface of the intraoral detector plate 3 but also reduces scrap caused by uneven force, improves the yield rate, and lowers production costs.

[0036] The supporting base 1 is detachably connected to the upper cover plate 2. This detachable connection is achieved through snap-fit ​​and / or fixing screws and / or hinges, with the number of screws ranging from 1 to 6. For example,... Figure 1 As shown, the supporting base 1 and the upper cover plate 2 are connected by fixing screws, with the four screws evenly distributed.

[0037] In a like Figures 1-4 In the specific embodiment shown, the limiting groove 11 extends inward from the side wall of the supporting base 1. The opening in the side wall of the limiting groove 11 facilitates the insertion or removal of the in-orifice detector plate 3.

[0038] In a like Figure 4 In a more specific embodiment shown, the inward extension length is less than the length of the intraoral detector plate, which is used to expose the corresponding part of the connecting gold wire of the intraoral detector plate. Along the length direction of the intraoral detector plate 3, an adhesive layer 31 is provided on the lower surface of one end of the intraoral detector plate 3 to cover and protect the connecting gold wire. The connecting gold wire is used to connect the conversion layer and the printed circuit board to realize signal transmission and processing. Since the connecting gold wire has poor mechanical strength and is easy to break, the setting that the connecting gold wire does not contact the limiting groove 11 avoids the gold wire from breaking due to uneven force, which would cause product scrap and improve the pass rate of the product after plating with Pyrene.

[0039] In a like Figures 1-3 In a more specific embodiment shown, the upper cover plate 2 has a U-shaped structure, and the open end of the U-shaped structure corresponds to the side wall opening of the limiting groove 11.

[0040] In a like Figures 1-3In the specific embodiment shown, the upper cover plate 2 has two opposing limiting edges 22, and the ratio of the opening width L1 of the limiting through hole 21 to the opening width L2 of the limiting groove 11 is 0.6 to 0.7. For example, the ratio can be 0.6, 0.61, 0.62, 0.63, 0.64, 0.65, 0.66, 0.67, 0.68, 0.69, or 0.70. If the ratio is too large, it will affect the limiting of the detector plate 3 inside the aperture; if the ratio is too small, it will affect the ability of cleaning tools such as knives to reach the bottom of the protective adhesive 31 for cleaning. In a case such as... Figures 1-3 In a more specific embodiment shown, the limiting edge 22 is formed on the edge of the upper cover plate 2 near the limiting through hole 21. Increasing the contact area with the intraoral detector plate 3 during cleaning of the protective adhesive 31 helps to ensure uniform force distribution on the intraoral detector plate 3.

[0041] In a like Figure 3 In the specific embodiment shown, the depth of the limiting groove 11 is 0.2 to 1 mm greater than the thickness of the intraoral flat panel detector plate. For example, it can be 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, or 1.0 mm. If the depth of the limiting groove 11 is too large, it will cause the intraoral flat panel detector plate 3 to have an excessively large tilt angle within the limiting groove 11 when cleaning the protective adhesive 31. This will cause the contact between the intraoral flat panel detector plate 3 and the fixing fixture to change from surface contact to line contact, resulting in uneven force and localized deformation.

[0042] In a like Figures 1-3 In the specific embodiment shown, the limiting edge 22 is a sloped structure.

[0043] In a more specific embodiment, the limiting edge 22 is inclined downward at an angle of 15 to 30°. When using a cleaning tool such as a knife or tweezers to pry off the protective adhesive from the bottom of the protective adhesive 31, the inclined surface can adjust the insertion angle of the cleaning tool such as the knife or tweezers so that it can reach the bottom of the protective adhesive 31 for cleaning.

[0044] This application does not specifically limit the shape of the bevel, as long as the insertion angle of the cleaning tool such as a knife or tweezers can be adjusted to the bottom of the protective adhesive 31 and the cleaning tool remains stable during the cleaning process. For example, the shape of the bevel can be a plane, an arc, a wavy surface, or a zigzag surface, etc. As an example, such as... Figure 2 The two sides and the bottom slope of the U-shaped top cover plate 2 are all flat, and the rounded corners are curved.

[0045] In one specific embodiment, the sidewall of the limiting groove 11 is provided with a silicone protective layer to prevent damage when the intraoral detector plate 3 contacts the side and / or end face of the limiting groove 11 during the cleaning process, thereby improving the product qualification rate.

[0046] This application does not specifically limit the shape and size of the support base 1, as long as it can accommodate the intraoral detector. For example, the support base 1 can be rectangular, circular, or trapezoidal. As an example, ... Figure 2 The supporting base 1 is rectangular.

[0047] In one specific embodiment, the upper cover plate 2 and the supporting base 1 are made of bakelite.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
