Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, and in particular to a working tip and a dental cleaning machine. Background Technology

[0002] When eating, food debris can remain on the surface, in the crevices, and at the roots of teeth. If oral hygiene is poor and food debris is not cleaned promptly, bacteria will cause plaque and tartar to form on the teeth, which are harmful to teeth and gums. To protect the health of your teeth and gums, regular dental cleanings are necessary.

[0003] A dental scaler is a device that uses ultrasonic technology to clean dental plaque and tartar. The component of the dental scaler that comes into direct contact with the teeth is the working tip, which is mounted on the handle of the scaler. The contact between the tip of the working tip and the teeth can be considered as point contact.

[0004] Existing cleaning tips present problems of inconvenience and poor cleaning effect when cleaning the middle position of the lingual-palatal side (the side closer to the tongue) of molars:

[0005] Molars are relatively large and located deep within the oral cavity. When cleaning the middle section of the lingual / palatal side of a molar, in addition to ensuring that the tip of the cleaning tool contacts this area, it is also necessary to ensure that other parts of the tool tip do not contact the tooth. To achieve this, the wrist holding the handle needs to be bent to a considerable extent. However, this grip is not only inconvenient to operate but also affects the force exerted by the hand, resulting in uneven contact force between the tip of the cleaning tool and the tooth, ultimately affecting the cleaning effect. Utility Model Content

[0006] The purpose of this invention is to overcome the defects of the prior art and provide a working tip and a dental cleaning machine. By setting a smooth curved part on the working rod of the working tip, the problems of inconvenient operation and poor cleaning effect when cleaning molars are solved.

[0007] To solve the above problems, this utility model provides: a working tip, including a connecting rod and a working rod, wherein the head end of the connecting rod is connected to the tail end of the working rod;

[0008] The working rod includes a smooth curved section;

[0009] There is a middle surface between the line connecting the centers of the head and tail ends of the connecting rod and the line connecting the centers of the head and tail ends of the working rod. The connecting rod and the working rod are placed on both sides of the middle surface, wherein the protrusion of the curved part faces the middle surface.

[0010] As a further improvement to the above technical solution, the angle between the line connecting the centers of the head and tail ends of the connecting rod and the line connecting the centers of the head and tail ends of the working rod is 30°~120°.

[0011] As a further improvement to the above technical solution, an arc transition section is provided between the head end of the connecting rod and the tail end of the working rod.

[0012] As a further improvement to the above technical solution, the connecting rod is a bent rod;

[0013] The connecting rod has an arc-shaped protrusion, wherein the protrusion of the arc-shaped protrusion faces the middle surface.

[0014] As a further improvement to the above technical solution, the midpoint of the arc-shaped protrusion does not protrude beyond the line connecting the center of the tail end of the connecting rod and the center of the head end of the working rod.

[0015] As a further improvement to the above technical solution, the connecting rod is a straight rod.

[0016] As a further improvement to the above technical solution, a first flow hole is provided inside the connecting rod, and a second flow hole is provided inside the working rod, wherein the first flow hole and the second flow hole are connected.

[0017] As a further improvement to the above technical solution, a connector is provided at the tail end of the connecting rod, and the head end of the connector is connected to the tail end of the connecting rod.

[0018] The connector has a threaded hole inside, which is connected to the first flow hole and penetrates the bottom surface of the connecting rod.

[0019] As a further improvement to the above technical solution, the shape of the connector is cylindrical or prismatic.

[0020] This utility model also provides: a dental cleaning machine, including the working tip described above.

[0021] The beneficial effects of this invention are as follows: The working tip includes a connecting rod and a working rod, the working rod having a smooth curved portion. Due to the positional relationship between the connecting rod and the working rod, and the convex direction of the curved portion, when cleaning the middle position on the lingual-palatal side of a patient's molar, the dentist's wrist does not need to bend or only needs to bend slightly to ensure that the tip of the working tip contacts this position, while maintaining sufficient distance between the working tip and the tooth at all other points except the tip.

[0022] Because of the small range of wrist flexion, the dentist can easily control the contact force between the tip of the cleaning tool and the middle position of the lingual and palatal side of the molar, thus ensuring the effectiveness of the cleaning.

[0023] This working tip is easy to use and can effectively improve the cleaning results. Attached Figure Description

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0033] See Figure 1 In this embodiment, a working tip is proposed, including a connecting rod 1 and a working rod 2, wherein the head end of the connecting rod 1 is connected to the tail end of the working rod 2. The length of the connecting rod 1 is greater than the length of the working rod 2, and the connecting rod 1 and the working rod 2 are an integral structure.

[0034] The working rod 2 includes a smooth curved portion 3, which can be obtained through processing techniques such as bending. Since the working tip needs to be placed in the oral cavity, the curved portion 3 must be smooth and free of sharp corners, burrs, etc., in order to protect the tissues inside the oral cavity from being scratched or punctured.

[0035] Because of the presence of the bend 3, a concave space 4 corresponding to the bend 3 will naturally form on the concave side of the bend 3.

[0036] Reference Figure 1 The protrusion of the curved part 3 faces the connecting rod 1, so that the concave space 4 can avoid the teeth during the teeth cleaning process. At the same time, due to the presence of the concave space 4, the working tip can be prevented from obstructing the view, allowing the dentist to more easily observe the surface condition of the teeth being cleaned.

[0037] like Figure 2 As shown, there is an intermediate surface 5 between the line connecting the centers of the head and tail ends of the connecting rod 1 and the line connecting the centers of the head and tail ends of the working rod 2. The connecting rod 1 and the working rod 2 do not intersect the intermediate surface 5 and are placed on both sides of the intermediate surface 5. The protrusion of the curved part 3 faces the intermediate surface 5.

[0038] The line connecting the centers of the head and tail ends refers to the line connecting the center of the head end and the center of the tail end; the middle surface 5 is a hypothetical surface. Figure 2 In the diagram, the two dashed lines represent the lines connecting the centers of the two ends of connecting rod 1 and the two ends of working rod 2, respectively, and the dotted line represents the intermediate surface 5. Due to the projection angle, Figure 2 The center plane is displayed as a line.

[0039] In this embodiment, the angle between the line connecting the centers of the two ends of the connecting rod 1 and the line connecting the centers of the two ends of the working rod 2 is 30° to 120°, including 30° and 120°. Theoretically, this angle can be set as needed, but given that the dimensions of the connecting rod 1, the working rod 2, and the curvature of the bent part 3 are fixed: if the angle is too small, it will affect the operation and may obstruct the view; if the angle is too large, it will affect the vibration transmission effect.

[0040] Reference Figure 2In this embodiment, the angle between the line connecting the centers of the two ends of the connecting rod 1 and the line connecting the centers of the two ends of the working rod 2 is 90°.

[0041] To avoid sharp parts, a rounded transition section 6 is provided between the head end of the connecting rod 1 and the tail end of the working rod 2.

[0042] like Figure 1 As shown, in this embodiment, connecting rod 1 is a bent rod.

[0043] The connecting rod 1 has an arc-shaped protrusion 7, wherein the protrusion direction of the arc-shaped protrusion 7 is towards the middle surface 5.

[0044] To control the curvature of the arc-shaped protrusion 7 and avoid affecting operation, the midpoint of the arc-shaped protrusion 7 does not protrude beyond the line connecting the center of the tail end of the connecting rod 1 and the head end of the working rod 2. Specifically, in Figure 1 The dashed line in the diagram represents the line connecting the center of the end of the connecting rod and the center of the beginning of the working rod 2.

[0045] The working tip is connected to the dental scaler's handle, and it uses vibrations to loosen or break up plaque, tartar, and calculus, thus cleaning the teeth. During this process, to enhance the cleaning effect, the teeth need to be continuously rinsed with water, which carries away the loosened debris.

[0046] To allow water to flow into the oral cavity for rinsing, a first flow hole is provided inside the connecting rod 1, and a second flow hole is provided inside the working rod 2. The first and second flow holes are connected, and the second flow hole passes through the working tip and forms an opening at the working tip. Water flows through the handle, through the first and second flow holes, and finally out from the opening at the working tip.

[0047] The position of the opening can be set according to actual needs, for example, it can be located on the side of the tip of the working point.

[0048] In order to connect to the dental cleaning handle, the tail end of the connecting rod 1 is provided with a connector 8, and the head end of the connector 8 is connected to the tail end of the connecting rod 1.

[0049] Furthermore, the connector 8 has a threaded hole 9 inside, which communicates with the first flow hole and penetrates the bottom surface of the connecting rod 1. The internal thread of the threaded hole 9 matches the external thread on the end of the dental cleaning handle.

[0050] In this embodiment, the connector 8 is cylindrical. In other embodiments, the connector 8 may also be prismatic or similar in shape.

[0051] This cleaning tip is easy to use and effectively improves teeth cleaning results. When cleaning the middle section of the lingual / palatal side of a patient's molars, the dentist's wrist does not need to bend, or only needs to be bent slightly, to ensure that the tip of the cleaning tip contacts this area while maintaining a certain distance between the tip and the tooth. Because of the small wrist bend, the dentist can easily control the contact force between the tip of the cleaning tip and the middle section of the lingual / palatal side of the molar, thus ensuring a thorough cleaning.

[0052] Since molars are located deep in the oral cavity, this working tip can effectively clean them. Therefore, it will be even easier and more convenient to clean teeth in other locations. Thus, the working tip proposed in this embodiment can not only effectively clean molars but also easily reach the middle positions of all teeth, specifically the area from the lingual ridge to the buccal ridge. A ridge is a longitudinal ridge on the axial surface extending from the cusp to the neck of the tooth. The ridge on the buccal surface of posterior teeth is called the buccal ridge, and the ridge on the lingual surface of canines and posterior teeth is called the lingual ridge.

[0053] In this embodiment, a dental cleaning machine is also proposed, including a dental cleaning handle and a working tip as described above, wherein the working tip is threadedly connected to the end of the dental cleaning handle via a connector 8. Example

[0054] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that the connecting rod 1 is a straight rod.

[0055] like Figure 4 As shown, the angle between the line connecting the centers of the two ends of connecting rod 1 and the line connecting the centers of the two ends of working rod 2 is different from that in Embodiment 1. In this embodiment, the angle is 60°.

[0056] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0057] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
