Description

Technical Field

[0001] This utility model relates to the field of dental instrument technology, specifically a replaceable dental probe. Background Technology

[0002] Dental probes are among the most commonly used instruments in clinical examination and treatment in dentistry. They are used to examine pits, fissures, cavities, and sensitive areas of teeth, as well as to probe periodontal pockets and sinus tracts, examine subgingival calculus, fillings, and the fit between restorations and crowns. They are also used to adjust the position of orthodontic brackets during bonding and to clean excess adhesive around the brackets.

[0003] For example, an existing Chinese patent (CN2125380U) discloses a dental probe that connects a rod with a curved needle to a holding rod using a tenon and a notch insertion method. Alternatively, the rod with the curved needle can be screwed to the holding rod using a nut or stud. After treating a patient, the rod with the curved needle can be pulled out, unscrewed, or discarded, and the holding rod can be connected to another new rod with a curved needle for later use. This avoids cross-infection of infectious diseases between patients.

[0004] However, the dental probe designed above still has some drawbacks in actual use: although the dental probe can be detached by using a threaded structure to avoid infection problems, the probe needs to apply force in the patient's mouth when using it, and the thread can easily rotate during the application of force, thus affecting the stability of the probe during use.

[0005] To address these issues, we designed a replaceable dental probe. Utility Model Content

[0006] The purpose of this invention is to provide a replaceable dental probe to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a replaceable dental probe, including a fixing rod and a connector threaded onto the top of the fixing rod. The probe body is provided on the top of the connector. A limiting cylinder and a fixing ring are respectively fixedly sleeved on the fixing rod and the connector. A sliding member is slidably arranged inside the limiting cylinder. A pull member is fixedly installed at the bottom of the sliding member. The bottom end of the pull member slides through the limiting cylinder. A locking member is provided on the top of the sliding member. A locking groove is opened at the bottom of the fixing ring. The top end of the locking member slides through the limiting cylinder and is inserted into the locking groove. A spring is provided on the top of the sliding member. The other end of the spring is located inside the limiting cylinder.

[0008] Furthermore, a pull block is fixedly installed at the end of the pull member away from the slider, and the outer surface of the pull block is provided with anti-slip texture.

[0009] Furthermore, the number of the sliding parts is two, and the number of the slots corresponds to the number of the sliding parts, and the two sliding parts are symmetrically slidably arranged in the limiting cylinder.

[0010] Furthermore, the limiting cylinder has two mounting cavities and a sliding opening respectively inside and at the top. The mounting cavity is connected to the sliding opening. The sliding member is slidably connected in the mounting cavity. The top end of the clamp is slidably inserted into the sliding opening. The end of the spring away from the sliding member is fixedly connected to the top wall of the mounting cavity.

[0011] Furthermore, two permanent magnets are symmetrically fixedly installed on the bottom wall of the mounting cavity, and two iron blocks are symmetrically arranged at the bottom of the slider. The iron blocks cooperate with the permanent magnets to resist each other and are magnetically connected.

[0012] Furthermore, two limiting rails are symmetrically opened on both sides of the limiting cylinder. The limiting rails are connected to the mounting cavity. Ball bearings are rotatably arranged on both sides of the slider, and the ball bearings are rolled and connected in the limiting rails.

[0013] Furthermore, limiting members are provided on both sides of the slider, and the ball is rotatably disposed within the limiting members, with a portion located outside the limiting members.

[0014] Furthermore, a threaded component is fixedly installed on the top of the fixing rod, and a threaded groove is opened at the bottom of the connector, with the threaded component threadedly inserted into the threaded groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by pulling down the puller, the puller can drive the sliding spring to move downward in the mounting cavity, so that the clip can slide completely out of the slot. Then, by rotating the connector, the connector can be detached from the fixed rod, which makes it easy to disassemble and replace the connector from the fixed rod. In use, by inserting the clip into the slot, the connector can be limited, preventing the connector from rotating on its own during use, thus improving the stability during use.

[0016] Compared with the prior art, the beneficial effects of this utility model are: when the permanent magnet is against the iron block, the permanent magnet can attract the iron block, which can easily position the sliding part, thus making it convenient for personnel to rotate the connecting part.

[0017] Compared with the prior art, the beneficial effects of this utility model are: during the sliding process of the slider, the slider will drive the ball to roll in the limiting rail, which can not only limit the slider in the mounting cavity and avoid the problem of movement deviation, but also change the sliding friction of the slider in the mounting cavity to rolling friction, thus making it easier for people to pull the block.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a replaceable dental probe, including a fixing rod 1 and a connector 2 threadedly sleeved on the top of the fixing rod 1. The top of the connector 2 is provided with a probe body 3. A limiting cylinder 5 and a fixing ring 4 are respectively fixedly sleeved on the fixing rod 1 and the connector 2. A sliding member 6 is slidably arranged inside the limiting cylinder 5. A pull member 7 is fixedly installed at the bottom of the sliding member 6. The bottom end of the pull member 7 slides through the limiting cylinder 5. A locking member 8 is provided at the top of the sliding member 6. A locking groove 9 is opened at the bottom of the fixing ring 4. The top end of the locking member 8 slides through the limiting cylinder 5 and is inserted into the locking groove 9. A spring 10 is provided at the top of the sliding member 6. The other end of the spring 10 is located inside the limiting cylinder 5. A threaded member 20 is fixedly installed at the top of the fixing rod 1. A threaded groove 19 is opened at the bottom of the connector 2. The threaded member 20 is threadedly inserted into the threaded groove 19.

[0022] In practice, the operator can hold the fixed rod 1 and then insert the connector 2 and probe body 3 into the patient's mouth to examine the teeth. After the patient's examination is completed and the connector 2 and probe body 3 are replaced, the puller 7 needs to be pulled down. This causes the puller 7 to pull the slide 6 and stretch the spring 10, which then moves downward within the mounting cavity 12 until the top of the clip 8 is completely slid out of the slot 9. Then, the connector 2 is rotated, allowing it to rotate off the fixed rod 1 and disengage from the threaded part 20. This makes it easy to remove and replace the connector 2 from the fixed rod 1. During use, the clip 8 is inserted into the slot 9 to limit the position of the connector 2, preventing it from rotating on its own and improving stability during use.

[0023] See Figure 1-4 A pull block 11 is fixedly installed at the end of the pull member 7 away from the slider 6. The outer surface of the pull block 11 is provided with anti-slip texture. By pulling the pull block 11, the pull member 7 can be moved, which makes it easier for the person to apply force when pulling the pull member 7. In addition, the anti-slip texture can increase the friction between the person's hand and the pull block 11, thereby avoiding the problem of hand slippage.

[0024] See Figure 1-4 There are two sliding parts 6, and the number of slots 9 corresponds to the number of sliding parts 6. The two sliding parts 6 are symmetrically slidably arranged in the limiting cylinder 5. The arrangement of the two sliding parts 6 can position both ends of the bottom of the fixing ring 4, thereby further improving the limiting ability of the connecting part 2.

[0025] See Figure 1-4 The limiting cylinder 5 has two mounting cavities 12 and a sliding opening 13 respectively inside and at its top. The mounting cavities 12 and the sliding opening 13 are connected. The sliding member 6 is slidably connected in the mounting cavity 12, and the top end of the locking member 8 is slidably inserted into the sliding opening 13. The end of the spring 10 away from the sliding member 6 is fixedly connected to the top wall inside the mounting cavity 12. This design facilitates the installation of components inside the limiting cylinder 5 and allows for normal movement of the components inside the limiting cylinder 5, avoiding motion interference problems.

[0026] It should be noted that for the installation of internal components of the limiting cylinder 5, the limiting cylinder 5 can be set in half first, which makes it easy to open the installation cavity 12 and the sliding port 13 inside the limiting cylinder 5, thus facilitating the installation of components. Finally, the two halves of the limiting cylinder 5 can be closed and installed.

[0027] See Figure 1-4 Two permanent magnets 14 are symmetrically fixedly installed on the bottom wall of the mounting cavity 12, and two iron blocks 15 are symmetrically arranged at the bottom of the slide 6. The iron blocks 15 and the permanent magnets 14 cooperate to resist each other and are magnetically connected.

[0028] In specific implementation, based on the above implementation, when the permanent magnet 14 and the iron block 15 are in contact, the permanent magnet 14 can attract the iron block 15, which can easily position the sliding part 6, thus making it convenient for personnel to rotate the connecting part 2.

[0029] It should be noted that the permanent magnet 14 can only generate magnetic force to attract the iron block 15 when the iron block 15 moves to half of the total distance between it and the permanent magnet 14, thus ensuring the stability of the permanent magnet 14 and preventing the iron block 15 from attracting the permanent magnet 14 on its own.

[0030] See Figure 1-4 Two limiting rails 16 are symmetrically opened on both sides of the limiting cylinder 5. The limiting rails 16 are connected to the mounting cavity 12. Rollers 18 are rotatably arranged on both sides of the sliding member 6. The rollers 18 are rotatably connected in the limiting rails 16. Limiting members 17 are opened on both sides of the sliding member 6. The rollers 18 are rotatably arranged in the limiting members 17, and part of them are located outside the limiting members 17.

[0031] In specific implementation, based on the above implementation, during the sliding process of the slider 6, the slider 6 will drive the ball 18 to roll in the limiting rail 16. This not only limits the slider 6 in the mounting cavity 12 to avoid the problem of movement deviation, but also changes the sliding friction of the slider 6 in the mounting cavity 12 to rolling friction, thus making it easier for personnel to pull the pull block 11.

[0032] Working principle: During use, the operator holds the fixing rod 1 and then drives the connector 2 and probe body 3 to be inserted into the patient's mouth to examine the teeth. After the patient's examination is completed and the connector 2 and probe body 3 are replaced, the pull block 11 needs to be pulled down. This allows the pull block 11 to drive the pull piece 7 and the slide piece 6 to stretch the spring 10 and move downwards within the mounting cavity 12 until the top of the locking piece 8 is completely slid out of the slot 9. Then, the connector 2 is rotated, allowing it to rotate off the fixing rod 1 and disengage from the threaded part 20. This makes it easy to remove and replace the connector 2 from the fixing rod 1. During use, the locking piece 8 is inserted into the slot 9 to limit the connection of the connector 2, preventing it from rotating on its own and improving stability during use.

[0033] During the above operation, when the permanent magnet 14 comes into contact with the iron block 15, the permanent magnet 14 can attract the iron block 15, which can easily position the sliding part 6, thus making it convenient for personnel to rotate the connecting part 2.

[0034] In addition, during the sliding process of the slider 6, the slider 6 will drive the ball 18 to roll in the limiting rail 16. This not only limits the slider 6 in the mounting cavity 12 to avoid the problem of movement deviation, but also changes the sliding friction of the slider 6 in the mounting cavity 12 to rolling friction, thus making it easier for people to pull the pull block 11.
