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 to which the probe tip reaches the bottom of the pocket (where the gum and tooth are joined) is the periodontal pocket depth. A normal periodontal pocket depth is 1-3 mm; a depth exceeding 3 mm may indicate periodontitis.

[0003] Various factors typically influence the accuracy of periodontal pocket depth measurements, with probing pressure (the pressure applied by the probe tip to the periodontal tissue) having a significant impact on the reliability of the results. A probing pressure of 20-25g is generally recommended, as this level is sufficient to detect the actual pocket depth without causing significant pain. The pressure is usually controlled by the dentist's feel and experience, which can lead to human error. Excessive pressure (greater than 30g) may puncture the gum line (the pocket floor), while insufficient pressure (less than 15g) may fail to detect the pocket floor. Both excessive and insufficient pressure affect the true pocket depth, thus impacting diagnosis and subsequent treatment. Experienced dentists find it relatively easy to determine if the probe has accurately reached the pocket floor; however, novice dentists may apply excessive pressure due to lack of skill, resulting in false probing depths. Utility Model Content

[0004] This application discloses a periodontal probe that allows users to more accurately detect the depth of periodontal pockets.

[0005] The periodontal probe includes: handle; Force application component, the force application component being mounted on the handle; and A probe is rotatably connected to the handle and is used to probe a target object. A force-applying component is used to prevent the probe from rotating relative to the handle, so that the periodontal probe remains in its initial state. When the probing force of the probe is greater than or equal to a preset value, at least a portion of the probe rotates in a first rotation direction, so that the periodontal probe changes from the initial state to a warning state. The preset value is 20g to 25g, and the first rotation direction is the direction away from the direction in which the probe tip is pointing.

[0006] In some embodiments, the force-applying component includes a power component and a force-transmitting component, wherein the power component always acts on the force-transmitting component along a first direction, such that the force-transmitting component always abuts against the probe. When the probe is driven by an external force and rotates in the first rotation direction, the probe pushes the force transmission member to move in the second direction. When the external force is removed from the probe, the power member drives the force transmission member to move in the first direction, so that the force transmission member pushes the probe to rotate in the second rotation direction. Wherein, the first direction is the direction in which the force transmission component moves toward the probe, the second direction is the opposite direction of the first direction, and the second rotation direction is the opposite direction of the first rotation direction.

[0007] In some embodiments, the force transmission member has a first inclined surface that is inclined relative to the first direction at one end near the probe, and the probe has a second inclined surface that is inclined relative to the first direction at one end near the force transmission member; When the periodontal probe is in the initial state, the first inclined surface is close to the second inclined surface; when the periodontal probe is in the warning state, the end of the probe near the force transmission member abuts against the first inclined surface.

[0008] In some embodiments, the probe includes a needle body and an abutment. The needle body is movably inserted into the end of the handle and is rotatably connected to the abutment. The abutment is rotatably connected to the handle, and one end of the abutment away from the needle body abuts against the force transmission member. When the needle tip of the needle body contacts a foreign object, the needle body will be affected by the reaction force of the foreign object and move relative to the handle. The needle body will drive the abutment to rotate in the first rotation direction, so that the abutment pushes the force transmission member to move in the second direction. When the needle tip of the needle body no longer contacts the foreign object, the power member drives the force transmission member to move in the first direction, so that the force transmission member pushes the abutment to rotate in the second rotation direction. The abutment then drives the needle body to move relative to the handle and return to its original position.

[0009] In some embodiments, the handle includes a handle body and an extension section, the extension section being connected to the end of the handle body, the needle body being movably inserted into the extension section, and the abutment being rotatably connected to the handle body.

[0010] In some embodiments, the power element is a spring, which is sleeved on the outer periphery of the force transmission element, and the spring always elastically abuts against the force transmission element along the first direction.

[0011] In some embodiments, the power component includes a first magnet and a second magnet, the first magnet being disposed on the force transmission component, and the second magnet always repelling the first magnet along the first direction, so that the first magnet acts on the probe.

[0012] In some embodiments, the handle has a receiving space and an opening, the opening being located at the end of the handle and communicating with the receiving space, the force-applying component being disposed within the receiving space, a portion of the probe being located within the receiving space of the handle, and another portion of the probe being located outside the handle, wherein when the periodontal probe is in the initial state, the probe passes through the opening; the handle also has a clearance opening, the clearance opening communicating with the receiving space and the opening, the clearance opening being located on the side of the handle opposite to the tip of the probe, wherein when the probe rotates in the first rotation direction, the probe can enter the clearance opening from the opening.

[0013] In some embodiments, the tip of the probe is provided with multiple scale segments.

[0014] In some embodiments, the periodontal probe further includes an adjustment member disposed at the end of the handle away from the probe needle, and the adjustment member is movable relative to the handle. The adjustment member is used to change the force applied by the force-applying component to the probe needle by moving relative to the handle, thereby changing the preset value.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: In the periodontal probe provided in this application, the probe needle is rotatably connected to the handle, and the handle is provided with a force-applying component. This component prevents the probe needle from rotating relative to the handle, thus maintaining the periodontal probe in its initial state. When the probing force of the probe needle is greater than or equal to a preset value, the probe needle rotates in a first rotation direction. The preset value is 20g~25g. Therefore, when using the periodontal probe provided in this application to probe the depth of periodontal pockets, the probing force of the probe needle can be gradually increased. If the probe needle suddenly rotates in the first rotation direction at a certain moment, it means that the probing force has just reached the preset value. In other words, the rotation of the probe needle serves as an early warning; the rotation in the first rotation direction reminds the user that the tip of the probe needle has just touched the bottom of the pocket without piercing it. Therefore, the detected depth of the periodontal pocket is relatively accurate. Thus, the periodontal probe provided in this application allows users to accurately probe the depth of periodontal pockets. Attached Figure Description

[0042] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0043] Please refer to Figures 1 to 3 This application provides a periodontal probe 1, which includes: a handle 10, a force application component 20, and a probe 30.

[0044] The handle 10 is used for gripping and is ergonomically designed for easy holding and operation. The surface of the handle 10 may have raised textures to improve grip stability. The cross-sectional shape of the handle 10 can be approximately circular, triangular, hexagonal, elliptical, etc. The material of the handle 10 can be, but is not limited to, metal, plastic, etc.

[0045] The force-applying component 20 is mounted on the handle 10. The probe 30 is rotatably connected to the handle 10, and the probe 30 has a tip away from the handle 10. The tip of the probe 30 is used to probe the target object, which can be a periodontal pocket. The force-applying component 20 is used to prevent the probe 30 from rotating relative to the handle 10, so that the periodontal probe 1 remains in its initial state. The initial state refers to the state of the periodontal probe 1 when it is not used and is not disturbed by human intervention; the initial state can also be called the natural state.

[0046] When the probing force of the probe 30 is greater than or equal to a preset value, at least a portion of the probe 30 rotates in the first rotation direction Y1, causing the periodontal probe 1 to change from the initial state (e.g., Figure 1 (as shown) changes to a warning state (e.g.) Figure 3 (As shown). The probing force refers to the pressure applied by the tip of the probe 30 to the target object. The first rotation direction Y1 is the direction away from the direction the tip of the probe 30 is pointing. The warning state refers to the state of the periodontal probe 1 after the probe 30 has rotated in the first rotation direction Y1. The preset value is 20g~25g, and the specific preset value can be set to 20g, 20.5g, 21g, 21.5g, 21.8g, 22g, 22.5g, 22.6g, 23g, 23.5g, 23.7g, 24g, 24.5g, 25g, etc.

[0047] It is understood that the aforementioned preset value is the critical force value for the probe 30 to rotate in the first rotation direction Y1. This application sets the critical force value (i.e., the preset value) to 20g~25g. A probing force of 20g~25g is sufficient to detect the actual periodontal pocket depth without piercing the pocket floor. Therefore, during the process of probing the periodontal pocket depth using the periodontal probe 1 provided by this application, the probing force of the probe 30 can be gradually increased. If the probe 30 suddenly rotates in the first rotation direction Y1 at a certain moment, it means that the probing force has just reached the preset value. In other words, the rotation of the probe 30 serves as an early warning; the rotation of the probe 30 in the first rotation direction Y1 reminds the user that the tip of the probe 30 has just touched the pocket floor without piercing it. Therefore, the periodontal pocket depth detected at this time is relatively accurate. Thus, the periodontal probe 1 provided by this application allows users to accurately detect the periodontal pocket depth.

[0048] Please refer to Figure 4 The force application component 20 includes a power component 210 and a force transmission component 220. Regardless of whether the periodontal probe 1 is in the initial state or the warning state, the power component 210 always acts on the force transmission component 220 along the first direction Z1 so that the force transmission component 220 always abuts against the probe 30, thus preventing the probe 30 from shaking.

[0049] When the probe 30 is rotated in the first rotation direction Y1 by an external driving force, the probe 30 pushes against the force transmission member 220 to move in the second rotation direction Z2. When the external driving force is removed from the probe 30, the power member 210 drives the force transmission member 220 to move in the first rotation direction Z1, so that the force transmission member 220 pushes the probe 30 to rotate in the second rotation direction Y2. It should be noted that the above-mentioned external driving force refers to an external force, for example, the force exerted by a person pressing the probe 30, or, for example, the reaction force experienced by the probe 30 when probing the periodontal pocket depth.

[0050] Wherein, the first direction Z1 is the direction from which the force transmission component 220 faces the probe 30, and this first direction Z1 is parallel to the length direction of the handle 10; the second direction Z2 is the opposite direction of the first direction Z1; and the second rotation direction Y2 is the opposite direction of the first rotation direction Y1.

[0051] Understandably, the above configuration allows the probe 30 to rotate back to its initial position in the second rotation direction Y2, regardless of how much it has rotated in the first rotation direction Y1. This ensures that the periodontal probe 1 is in its initial state, meaning the probe 30 has an automatic return function and does not require manual adjustment.

[0052] It should be noted that when the periodontal probe 1 is in the initial state, in one embodiment, the force exerted by the force application component 20 on the probe needle 30 can just pass through the rotation center axis of the probe needle 30, at which time the probe needle 30 does not have a rotational tendency; in another embodiment, the force exerted by the force application component 20 on the probe needle 30 may not pass through the rotation center axis of the probe needle 30, so that the probe needle 30 has a tendency to rotate in the second rotation direction Y2.

[0053] It should be noted that, in this application, the rotation of the probe 30 in the first rotation direction Y1 and the second rotation direction Y2 can be either the entire probe 30 rotating or only a part of the probe 30 rotating. These two forms will be given separately later.

[0054] Example 1: The entire probe is rotated. Please refer to Figures 5 to 7The force transmission component 220 has a first inclined surface M1 at one end near the probe 30, which is inclined relative to the first direction Z1. That is, the angle formed between the straight line parallel to the first direction Z1 and the first inclined surface M1 is greater than 0° and less than 90°.

[0055] The probe 30 has a second inclined surface M2 at one end near the force transmission member 220, which is inclined relative to the first direction Z1. That is, the angle formed between the straight line parallel to the first direction Z1 and the second inclined surface M2 is greater than 0° and less than 90°.

[0056] When the periodontal probe 1 is in its initial state, the first inclined surface M1 is pressed tightly against the second inclined surface M2, as follows: Figure 5 As shown, the contact area between the probe 30 and the force transmission member 220 is large due to the contact between the first inclined surface M1 and the second inclined surface M2, thereby ensuring that the periodontal probe 1 can be stably maintained in the initial state. When the periodontal probe 1 is in the warning state, the probe 30 abuts against the first inclined surface M1 at the end of the force transmission member 220 (hereinafter referred to as the abutment end 321), as shown. Figure 6 and Figure 7 As shown. That is to say, regardless of whether the periodontal probe 1 is in the initial state or the warning state, the first inclined surface M1 will abut against the probe needle 30. It can be seen that the setting of the first inclined surface M1 realizes the mutual conversion between the rotational motion of the probe needle 30 and the linear motion of the force transmission component 220.

[0057] During the transition from the initial state to the warning state of the periodontal probe 1 (i.e., as the probe 30 gradually rotates in the first rotation direction Y1), the first inclined surface M1 disengages from the second inclined surface M2, and the abutment end 321 slides from the upper part to the lower part of the first inclined surface M1. The abutment end 321, by pushing against the first inclined surface M1, causes the force transmission component 220 to gradually move in the second direction Z2. During the transition from the warning state to the initial state of the periodontal probe 1 (i.e., as the probe 30 gradually rotates in the second rotation direction Y2), the power component 210 drives the force transmission component 220 to gradually move in the first direction Z1, thereby causing the abutment end 321 to slide from the lower part of the first inclined surface M1 to the upper part of the first inclined surface M1, until the first inclined surface M1 and the second inclined surface M2 are in contact.

[0058] It is understandable that during the switching between the initial state and the warning state, the contact end 321 of the periodontal probe 1 not only slides on the first inclined surface M1, but also rotates on the first inclined surface M1. That is, the movement of the contact end 321 on the first inclined surface M1 is sliding-rotating. For this purpose, a fillet 3211 can be provided on the contact end 321 (e.g., Figure 7 As shown), this allows the abutment end 321 to slide more smoothly on the first inclined surface M1.

[0059] Example 2: Part of the probe rotates. Please refer to Figures 8 to 10 The probe 30 includes a needle body 310 and an abutment 320. The needle body 310 is movably inserted into the end of the handle 10. Specifically, the end of the handle 10 has a through hole X5, and the needle body 310 can be movably inserted into the through hole X5. It can be understood that the needle body 310 inserted into the through hole X5 can basically only move along the axis of the through hole X5, thereby avoiding large-scale shaking of the needle body 310. Furthermore, the needle body 310 is rotatably connected to the abutment 320, and the abutment 320 is rotatably connected to the handle 10 through a rotating shaft 40, and the end of the abutment 320 away from the needle body 310 movably abuts against the force transmission member 220.

[0060] When the tip of the needle body 310 contacts a foreign object, the needle body 310 will move relative to the handle 10 due to the reaction force of the foreign object. The needle body 310 will also drive the abutment member 320 to rotate relative to the handle 10 in the first rotational direction Y1, causing the abutment member 320 to push the force transmission member 220 in the second direction Z2. During this process, the needle body 310 and the abutment member 320 rotate relative to each other, and the included angle between them gradually decreases.

[0061] When the needle tip of the needle body 310 no longer contacts the foreign object, the power component 210 drives the force transmission component 220 to move in the first direction Z1, so that the force transmission component 220 pushes the abutment component 320 to rotate relative to the handle 10 in the second rotation direction Y2. The abutment component 320 then drives the needle body 310 to move relative to the handle 10 and return to its original position. During this process, the needle body 310 and the abutment component 320 rotate relative to each other, and the included angle between them gradually increases.

[0062] The handle 10 includes a handle body 110 and an extension section 120. The extension section 120 is connected to the end of the handle body 110. The needle body 310 is movably inserted into the extension section 120. The abutment 320 is rotatably connected to the handle body 110.

[0063] The handle 110 has a receiving space X1 and an opening X2. The opening X2 is located at the end of the handle 110 and communicates with the receiving space X1. The force-applying component 20 is disposed within the receiving space X1. A portion of the probe 30 is located within the receiving space X1 of the handle 110, and the other portion of the probe 30 is located outside the handle 110. When the periodontal probe 1 is in the initial state, the probe 30 passes through the opening X2.

[0064] The handle 110 is also provided with a clearance opening X3, which connects the receiving space X1 and the opening X2. The clearance opening X3 is located on the side of the handle 110 opposite to the direction in which the probe tip of the probe 30 is facing. When the probe 30 rotates in the first rotation direction Y1, the probe 30 can enter the clearance opening X3 from the opening X2.

[0065] It should be noted that the following content is based on the structure corresponding to "Example 1: the entire probe rotates" described above for illustrative purposes only. In the absence of any contradictions, the following content can be applied to the scheme corresponding to "Example 2: a part of the probe rotates".

[0066] The following describes two feasible implementation forms of the power component 210 with reference to the attached drawings.

[0067] First implementation form: Spring type Please refer to Figure 4 The power component 210 is a spring, which can be a tension spring or a compression spring, and can generate elastic force in the length direction. The spring is sleeved on the outer periphery of the force transmission component 220, and the spring always elastically abuts against the force transmission component 220 along the first direction Z1. That is, the spring applies an elastic force to the force transmission component 220 along the first direction Z1, thereby causing the force transmission component 220 to act on the probe 30.

[0068] It should be noted that in this embodiment, the spring can be in a stretched state or a compressed state. A stretched state refers to the spring being elongated from its initial length, while a compressed state refers to the spring being shortened from its initial length. The initial length refers to the natural length of the spring when not subjected to any external force. This application only illustrates the spring in a compressed state as an example.

[0069] Please refer to Figure 11 In one embodiment, the force transmission member 220 may include a rod body portion 221, an annular portion 222, and an abutment portion 223 connected in sequence. The abutment portion 223 is used to abut the probe 30. A spring is sleeved on the outer periphery of the rod body portion 221, and one end of the spring elastically abuts against the annular portion 222, while the other end elastically abuts against the handle 10.

[0070] Please refer to Figure 12In another embodiment, the periodontal probe 1 further includes an adjusting member 50, which is disposed at the end of the handle 10 away from the probe needle 30, and is movable relative to the handle 10. The adjusting member 50 is used to change the force applied by the force-applying component 20 to the probe needle 30 by moving relative to the handle 10, thereby changing the preset value. Specifically, the periodontal probe 1 further includes an adjusting member 50, which is movably disposed at the end of the handle 10 away from the probe needle 30. The adjusting member 50 has a receiving hole X4 through which the force-transmitting component 220 is inserted. The force transmission component 220 may include a rod portion 221, an annular portion 222, and an abutment portion 223 connected in sequence. The abutment portion 223 abuts against the probe 30. A spring is sleeved on the outer periphery of the rod portion 221, with one end of the spring elastically abutting against the annular portion 222 and the other end abutting against the adjusting component 50. The adjusting component 50 adjusts the length of the spring by moving relative to the handle 10 in a first direction Z1 or a second direction Z2. That is, when the adjusting component 50 moves in the first direction Z1 or the second direction Z2, it causes the spring to shorten or lengthen, thereby changing the spring's length. After the spring's length changes, the elastic force exerted by the spring on the force transmission component 220 changes, and the difficulty of the probe 30 transitioning from its initial state to the warning state changes; that is, the preset value will change. Furthermore, by providing the receiving hole X4, the adjusting member 50 and the force transmission member 220 can move relative to each other in the first direction Z1 or the second direction Z2. For example, when the adjusting member 50 moves relative to the handle 10, the adjusting member 50 will move relative to the force transmission member 220. Similarly, when the probe 30 rotates, the force transmission member 220 will move relative to the adjusting member 50. It is understood that by providing the adjusting member 50, this embodiment allows the user to adjust the aforementioned preset value according to their needs.

[0071] Please refer to Figure 12Optionally, the adjusting member 50 is threadedly connected to the handle 10. Specifically, the adjusting member 50 is inserted into the handle 10, which has an internal thread, while the adjusting member 50 has an external thread. The adjusting member 50 and the handle 10 are screwed together by the internal and external threads. When the adjusting member 50 rotates clockwise or counterclockwise, it drives the spring to extend or shorten. Further, a portion of the adjusting member 50 is located inside the handle 10, and another portion is located outside the handle 10. This configuration allows the user to directly screw on the adjusting member 50 located outside the handle 10. Example: Assume the current preset value of the periodontal probe 1 is 22g. If the user screws on the adjusting member 50 clockwise, the adjusting member 50 moves in the first direction Z1, causing the spring to shorten. This increases the elastic force of the spring on the force transmission member 220, strengthening the contact force between the force transmission member 220 and the probe 30, thereby increasing the preset value from 22g to 23g. If the user turns the adjusting component 50 counterclockwise, the adjusting component 50 will move in the second direction Z2, causing the spring to extend. This reduces the elastic force of the spring on the force transmission component 220, weakens the contact between the force transmission component 220 and the probe 30, and thus reduces the preset value from 22g to 21g.

[0072] Please refer to Figure 13 Optionally, the adjusting member 50 may be provided with multiple scale lines 510, which are arranged at intervals along the length direction of the adjusting member 50 (which is parallel to the first direction Z1). Each scale line 510 corresponds to a scale value 520, and each scale value 520 represents a different preset value. When the end face M3 of the handle 10 away from the probe 30 is aligned with a certain scale line 510, the scale value 520 corresponding to that scale line 510 is the current preset value of the periodontal probe 1. (Example description follows) Figure 13 As shown): The adjusting member 50 has three scale lines 510: a first scale line 511, a second scale line 512, and a third scale line 513, and three scale values ​​520: a first scale value 521 (21g), a second scale value 522 (22g), and a third scale value 523 (23g). The first scale value 521 corresponds to the first scale line 511, the second scale value 522 corresponds to the second scale line 512, and the third scale value 523 corresponds to the third scale line 513. When the adjustment member 50 is moved so that the first scale value 521 is aligned with the end face M3 of the handle 10, the preset value of the periodontal probe 1 is 21g; when the adjustment member 50 is moved so that the second scale value 522 is aligned with the end face M3 of the handle 10, the preset value of the periodontal probe 1 is 22g; when the adjustment member 50 is moved so that the third scale value 523 is aligned with the end face M3 of the handle 10, the preset value of the periodontal probe 1 is 23g.

[0073] The above is an introduction to the use of a spring in the power component 210.

[0074] Second implementation method: Magnet form Please refer to Figure 14 The power component 210 includes a first magnet 211 and a second magnet 212. The first magnet 211 is disposed on the force transmission component 220, and the second magnet 212 always repels the first magnet 211 along the first direction Z1, so that the first magnet 211 acts on the probe 30. That is, the first magnet 211 and the second magnet 212 are opposite each other with the same poles; they can be arranged with their N poles opposite each other or their S poles opposite each other.

[0075] Please refer to Figure 14 In one embodiment, the force transmission member 220 may include a rod body portion 221, an annular portion 222, and an abutment portion 223 connected in sequence. The abutment portion 223 is used to abut the probe 30. A spring is sleeved on the outer periphery of the rod body portion 221. A first magnet 211 is disposed on one side of the annular portion 222, and a second magnet 212 is connected to the handle 10.

[0076] Please refer to Figure 15In another embodiment, the periodontal probe 1 further includes an adjusting member 50, which is disposed at the end of the handle 10 away from the probe needle 30, and is movable relative to the handle 10. The adjusting member 50 is used to change the force applied by the force-applying component 20 to the probe needle 30 by moving relative to the handle 10, thereby changing the preset value. Specifically, the periodontal probe 1 further includes an adjusting member 50, which is movably disposed at the end of the handle 10 away from the probe needle 30. The adjusting member 50 has a receiving hole X4 through which the force-transmitting component 220 is inserted. The force transmission component 220 may include a rod portion 221, an annular portion 222, and an abutment portion 223 connected in sequence. The abutment portion 223 abuts against the probe 30. A first magnet 211 and a second magnet 212 are both sleeved on the outer periphery of the rod portion 221. The first magnet 211 is located on the side of the annular portion 222 near the second magnet 212, and the second magnet 212 is located on the side of the adjusting component 50 near the first magnet 211. The first magnet 211 and the annular portion 222 may or may not be fixedly connected. The second magnet 212 and the adjusting component 50 may or may not be fixedly connected. The adjusting component 50 adjusts the distance between the first magnet 211 and the second magnet 212 by moving relative to the handle 10 in a first direction Z1 or a second direction Z2. In other words, when the adjusting member 50 moves in the first direction Z1 or the second direction Z2, it will cause the second magnet 212 to move closer to or further away from the first magnet 211, thereby changing the distance between the two magnets. After the distance between the two magnets changes, the force exerted by the first magnet 211 on the force transmission member 220 will change, and the difficulty for the probe 30 to switch from the initial state to the warning state will change, that is, the preset value will change. In addition, by providing the receiving hole X4, the adjusting member 50 and the force transmission member 220 can generate relative movement in the first direction Z1 or the second direction Z2. For example, when the adjusting member 50 moves relative to the handle 10, the adjusting member 50 will move relative to the force transmission member 220. Or, for example, when the probe 30 rotates, the force transmission member 220 will move relative to the adjusting member 50. It can be understood that by providing the adjusting member 50, this embodiment allows the user to adjust the above-mentioned preset value according to their needs.

[0077] Please refer to Figure 15Optionally, the adjusting member 50 is threadedly connected to the handle 10. Specifically, the adjusting member 50 is inserted into the handle 10, which has an internal thread, while the adjusting member 50 has an external thread. The adjusting member 50 and the handle 10 are screwed together by the internal and external threads. When the adjusting member 50 rotates clockwise or counterclockwise, it drives the second magnet 212 away from or towards the first magnet 211. Further, a portion of the adjusting member 50 is located inside the handle 10, and another portion is located outside the handle 10. This configuration allows the user to directly screw on the adjusting member 50 located outside the handle 10. Example: Assume the current preset value of the periodontal probe 1 is 22g. If the user rotates the adjusting member 50 clockwise, the adjusting member 50 moves in the first direction Z1, causing the second magnet 212 to move closer to the first magnet 211. This increases the force exerted by the first magnet 211 on the force transmission member 220, thus strengthening the contact between the force transmission member 220 and the probe 30, thereby increasing the preset value from 22g to 23g. If the user rotates the adjusting member 50 counterclockwise, the adjusting member 50 moves in the second direction Z2, causing the second magnet 212 to move away from the first magnet 211. This decreases the force exerted by the first magnet 211 on the force transmission member 220, weakening the contact between the force transmission member 220 and the probe 30, thereby decreasing the preset value from 22g to 21g.

[0078] Please refer to Figure 16 Optionally, the adjusting member 50 may be provided with multiple scale lines 510, which are arranged at intervals along the length direction of the adjusting member 50 (which is parallel to the first direction Z1). Each scale line 510 corresponds to a scale value 520, and each scale value 520 represents a different preset value. When the end face M3 of the handle 10 away from the probe 30 is aligned with a certain scale line 510, the scale value 520 corresponding to that scale line 510 is the current preset value of the periodontal probe 1. (Example description follows) Figure 16 As shown): The adjusting member 50 has three scale lines 510: a first scale line 511, a second scale line 512, and a third scale line 513, and three scale values ​​520: a first scale value 521 (21g), a second scale value 522 (22g), and a third scale value 523 (23g). The first scale value 521 corresponds to the first scale line 511, the second scale value 522 corresponds to the second scale line 512, and the third scale value 523 corresponds to the third scale line 513. When the adjustment member 50 is moved so that the first scale value 521 is aligned with the end face M3 of the handle 10, the preset value of the periodontal probe 1 is 21g; when the adjustment member 50 is moved so that the second scale value 522 is aligned with the end face M3 of the handle 10, the preset value of the periodontal probe 1 is 22g; when the adjustment member 50 is moved so that the third scale value 523 is aligned with the end face M3 of the handle 10, the preset value of the periodontal probe 1 is 23g.

[0079] The above is an introduction to the use of magnets in the power component 210.

[0080] Please refer to Figures 17 to 19 The handle 10 has a receiving space X1 and an opening X2. The opening X2 is located at the end of the handle 10 and communicates with the receiving space X1. The force-applying component 20 is disposed within the receiving space X1. A portion of the probe 30 is located within the receiving space X1 of the handle 10, and the other portion of the probe 30 is located outside the handle 10. When the periodontal probe 1 is in the initial state, the probe 30 passes through the opening X2.

[0081] Please refer to Figures 17 to 19 The handle 10 is also provided with a clearance opening X3, which connects the receiving space X1 and the opening X2. The clearance opening X3 is located on the side of the handle 10 opposite to the tip of the probe 30. When the probe 30 rotates in the first rotation direction Y1, the probe 30 can enter the clearance opening X3 from the opening X2.

[0082] Please refer to Figure 19 The periodontal probe 1 also includes a rotating shaft 40, through which the probe 30 is rotatably connected to the handle 10. In one embodiment, the rotating shaft 40 is fixed to the handle 10 (e.g., the rotating shaft 40 is fixed to the handle 10 by bonding or interference fit), and the probe 30 is rotatably sleeved on the rotating shaft 40. In another embodiment, the rotating shaft 40 is fixed to the probe 30 (e.g., the rotating shaft 40 is fixed to the probe 30 by bonding or interference fit), and the rotating shaft 40 is rotatably connected to the handle 10. Of course, there are other connection methods between the rotating shaft 40, the probe 30, and the handle 10, which will not be listed here.

[0083] Please refer to Figure 20 The probe 30 includes a needle body 310 and an abutment 320 connected to each other, with the abutment 320 rotatably connected to the handle 10. The needle body 310 is the component used to detect the depth of periodontal pockets. The abutment 320 abuts against the force transmission component 220 of the force application assembly 20. In one embodiment, the needle body 310 and the abutment 320 are detachably connected, for example, by threaded connection, snap-fit ​​connection, or screw connection, which facilitates subsequent maintenance and replacement. In another embodiment, the needle body 310 and the abutment 320 are non-detachably connected, for example, by bonding or welding, which improves overall consistency and prevents the needle body 310 from easily wobbling or falling off. In yet another embodiment, the needle body 310 and the abutment 320 are an integral structure made of the same material, which provides better structural strength.

[0084] Please refer to Figure 21 The probe 30 has multiple graduated segments 311 at its tip. These graduated segments 311 indicate the current depth at which the probe tip is inserted into the periodontal pocket, which is the desired periodontal pocket depth. In other words, during the periodontal pocket depth measurement, if the user observes that the probe 30 has rotated, indicating that the probe tip has reached the bottom of the periodontal pocket, the insertion can be stopped, and the exposed state of the graduated segments 311 can be observed to estimate the insertion depth of the probe tip.

[0085] The number of scale segments 311 can be, but is not limited to, 2, 3, 4, etc.

[0086] The length of each scale segment 311 can be the same or different. For example, the length of each scale segment 311 can be 3mm, 4mm, 5mm, etc. Or, for example, some scale segments 311 have a length of 3mm and some scale segments 311 have a length of 1mm.

[0087] Adjacent scale segments 311 can be different colors to facilitate determining the estimated insertion depth. For example, the scale segments 311 can be set with alternating black and yellow colors. Alternatively, different scale segments 311 can be different colors such as black, yellow, and blue.

[0088] Example illustration: such as Figure 21 As shown, scale segment 311 includes a first scale segment 3111, a second scale segment 3112, and a third scale segment 3113. The length of the first scale segment 3111, the second scale segment 3112, and the third scale segment 3113 is 3mm. The first scale segment 3111 is green, the second scale segment 3112 is yellow, and the third scale segment 3113 is red.

[0089] It is understood that the periodontal probe 1 provided in this application can be disinfected before use to avoid the spread of bacteria. Optionally, in the above-mentioned spring-type or magnet-type solutions, the spring (or magnet) can be enclosed in the handle 10 to isolate the spring (or magnet) from the outside world, preventing disinfectant from entering the space containing the spring (or magnet) and causing the spring (or magnet) to be disturbed, thereby affecting the normal force value (i.e., the aforementioned preset value).

[0090] The technical means disclosed in this application are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. 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.
