[0037] As shown in Figure 1 The utility model discloses an embodiment provides a multifunctional dental curet, including spoon handle 100, curet 200, adjusting assembly 300, limiting component 400.

[0038] The curet 200 is arranged at one end of the spoon handle 100;The adjusting assembly 300 is arranged between the spoon handle 100 and the curet 200, to enable the curet 200 to swing relative to the spoon handle 100;The limiting component 400 is arranged on the spoon handle 100, to limit the relative position of the curet 200 and the spoon handle 100.

[0039] The multifunctional dental curet provided in the embodiment is in the unlocked state before use, and medical staff can hold the spoon handle 100 and drive the curet 200 to swing relative to the spoon handle 100 according to the specific condition and treatment requirement of the patient, so as to be adjusted to a most suitable working angle.The adjustment process is not only simple and fast, but also can ensure that the curet 200 can accurately act on the diseased part in the subsequent treatment process.

[0040] Once the angle adjustment of the curet 200 is completed, the relative position between the curet 200 and the spoon handle 100 can be limited by operating the limiting component 400, to ensure that the curet 200 does not shake or deviate accidentally in the treatment process.This design not only improves the accuracy and safety of treatment, but also helps medical staff to focus more on treatment itself, so as to ensure the smooth progress of the treatment process.

[0041] More advanced, the multifunctional dental curette of the present embodiment also takes into account the dynamic needs during the treatment process. Even after the treatment has started, if the medical staff finds that the angle of the curette 200 needs to be fine-tuned to adapt to the new treatment situation, the relative position of the curette 200 and the handle 100 can also be conveniently unlocked by the limiting assembly 400. After unlocking, the curette 200 becomes swingable again, and the medical staff can make further adjustments according to actual needs until the optimal treatment angle is reached. This design greatly reduces the need for frequent replacement of instruments during treatment, not only saving valuable time, but also effectively improving the overall treatment efficiency.

[0042] In combination Figure 2 , Figure 3 As shown in FIG. 3, in some specific embodiments, the adjustment assembly 300 includes a hinged seat 310 and a hinged ball 320, the hinged seat 310 is arranged on the handle 100, the hinged seat 310 has a hinged groove 311 corresponding to the hinged ball 320, the hinged ball 320 is connected with the curette 200 and embedded in the hinged groove 311, and the hinged ball 320 can rotate in the hinged groove 311. When the hinged ball 320 is embedded in the hinged groove 311, a unique rotation mechanism begins to work. This mechanism allows the hinged ball 320 to rotate freely and smoothly in the hinged groove 311, thereby achieving the relative swing between the curette 200 and the handle 100.

[0043] It is worth mentioning that this relative swing adjustment mode realizes the characteristics of infinite adjustment. That is, the user can make subtle and accurate adjustments to the shape of the curette 200 according to actual needs, without being limited by fixed adjustment gears. This design makes the present embodiment more easily adapt to different patients or different lesion conditions, so as to adjust the most suitable shape to treat the patient.

[0044] This infinite adjustment design not only improves the treatment effect, so that the doctor can more accurately locate the lesion site and perform effective treatment operation; at the same time, it also reduces the treatment difficulty and relieves the doctor's work burden.

[0045] As Figure 4As shown, in some specific embodiments, the limiting assembly 400 comprises a rotating rod 410, and the spoon handle 100 is provided with a limiting channel 110 corresponding to the rotating rod 410, the limiting channel 110 being in communication with the hinged groove 311, and the rotating rod 410 is threaded into the limiting channel 110. As the rotating rod 410 gradually approaches, it will eventually come into contact with the hinged ball 320 and effectively limit the relative position between the hinged ball 320 and the hinged groove 311 through a tight-fitting manner. The end of the rotating rod 410 away from the hinged ball 320 is threaded out of the limiting channel 110. In this way, medical staff do not need to directly contact the spatula 200 part, but only need to operate at the end away from the spatula 200 to complete the locking or unlocking action between the spatula 200 and the spoon handle 100. This design not only makes the operation more simple and efficient, but also enables medical staff to easily perform locking or unlocking control when the spatula 200 is in the patient's ear, greatly improving flexibility and safety during treatment.

[0046] In some specific embodiments, the limiting assembly 400 further comprises a movable rod 420, which is threaded into the limiting channel 110 and located between the rotating rod 410 and the hinged ball 320. The rotation of the rotating rod 410 relative to the spoon handle 100 can push the movable rod 420 towards the hinged ball 320 and abut against the surface of the hinged ball 320. The ingenuity of this design lies in that it effectively solves the problem that may occur when the rotating rod 410 is tightened against the hinged ball 320 after adjusting the relative angle between the spatula 200 and the spoon handle 100 and completing the adjustment. Specifically, without the presence of the movable rod 420, the tightening end of the rotating rod 410 may drive the hinged ball 320 to rotate when it is rotated, thereby causing unnecessary movement of the spatula 200 and affecting the accuracy of the adjustment. However, with the movable rod 420, this problem is effectively solved.

[0047] When the rotating rod 410 is rotated and pushes the movable rod 420, the movable rod 420 will only approach the hinged ball 320 along the limiting channel 110 and will not rotate. This design ensures that no additional rotating force is generated when the hinged ball 320 is tightened, thereby improving the accuracy of the relative limiting of the hinged ball 320 and the hinged groove 311. This improvement in accuracy is crucial for ensuring the adjustment of the relative position between the spatula 200 and the spoon handle 100, making the entire medical device more stable and reliable during use, and improving the accuracy and safety of treatment.

[0048] In some specific embodiments, the handle 100 is composed of multiple components connected by screwing or the like. This multi-component design allows the handle 100 to have great length adjustability, so that medical staff can freely select and combine different numbers of components according to actual treatment needs, thereby accurately determining the final length of the handle 100.

[0049] More importantly, considering the variety of lengths of the handle 100, the rotating rod 410 passing through the limiting channel 110 is also optimized accordingly. The length of the rotating rod 410 is not fixed, but can be flexibly selected or increased or decreased in number according to the length of the selected handle 100. This design ensures that the rotating rod 410 can consistently play its limiting role regardless of the length of the handle 100, and maintain effective contact and tight fit with the articulated ball 320.

[0050] Through this multi-component combination and length-adjustable design of the rotating rod 410, the medical instrument of the present embodiment can be applied to more use scenarios. Whether it is for individual differences of different patients or to meet different treatment needs, medical staff can easily adjust the length of the handle 100 to ensure that the spatula 200 can accurately reach the target position and achieve precise treatment.

[0051] In some specific embodiments, the side of the movable rod 420 is provided with a first spline 421, and the movable rod 420 is connected with the limiting channel 110 through a key groove. This design not only enhances the structural strength of the movable rod 420, but more importantly, it makes it possible to achieve stable connection between the movable rod 420 and the limiting channel 110.

[0052] At the same time, the inner wall of the limiting channel 110 is also provided with a key groove matching the first spline 421. When the movable rod 420 passes through the limiting channel 110, a close fitting relationship is formed between the first spline 421 and the key groove. This fitting relationship not only ensures the stable positioning of the movable rod 420 in the limiting channel 110, but more importantly, it effectively limits the rotational freedom of the movable rod 420 during extension and retraction.

[0053] In other words, even if the rotating rod 410 exerts a pushing force on the movable rod 420, due to the close fitting between the first spline 421 and the key groove, the movable rod 420 will only move in the direction of the limiting channel 110, and will not rotate unnecessarily with the rotating rod 410. This design greatly improves the stability and accuracy of the movable rod 420 during movement, thereby ensuring the reliability and accuracy of the entire limiting assembly 400 when the articulated ball 320 is tightened.

[0054] In some specific embodiments, the end of the rotating rod 410 away from the articulated ball 320 is provided with a rotating handle 411, which facilitates the rotating operation of the rotating rod 410 by medical staff.

[0055] In some specific embodiments, the spatula 200 is provided with a mounting rod 210, the articulated ball 320 is provided with a mounting seat 321, the mounting seat 321 is provided with a mounting groove 322, the mounting rod 210 is arranged in the mounting groove 322, and the mounting rod 210 and the mounting groove 322 are connected by a connecting piece. This connecting piece can be a locking screw, a buckle structure or other reliable fasteners, which can stably fix the mounting rod 210 in the mounting groove 322 and prevent the spatula 200 from loosening or falling off during use.

[0056] Through this design, medical staff can easily replace the spatula 200 on the articulated ball 320 according to actual treatment needs. Whether it is for the treatment needs of different patients or to cope with the wear and tear and damage of the spatula 200, the old spatula 200 can be removed and a new spatula 200 can be installed by simply disassembling the connecting piece. This flexibility and maintainability greatly improves the practicality and service life of medical equipment.

[0057] In some specific embodiments, the connecting piece includes a first magnetic piece 220 and a second magnetic piece 323. The first magnetic piece 220 is arranged on the mounting rod 210, and the second magnetic piece 323 is arranged in the mounting groove 322. The first magnetic piece 220 and the second magnetic piece 323 are made of high-performance permanent magnetic material and have strong magnetic attraction and stable magnetic performance. The first magnetic piece 220 and the second magnetic piece 323 can be relatively adsorbed, which facilitates the quick assembly or disassembly of the spatula 200 and the articulated ball 320.

[0058] When the spatula 200 needs to be assembled on the articulated ball 320, the mounting rod 210 is only needed to be aligned with the mounting groove 322 and gently approached. The first magnetic piece 220 and the second magnetic piece 323 will immediately generate strong magnetic attraction and tightly adsorb each other. This magnetic attraction type connection is not only easy to operate, but also firmly connected, which can maintain a stable connection state even in a complex treatment environment.

[0059] Similarly, when the spatula 200 needs to be disassembled, the mounting rod 210 can be pulled out of the mounting groove 322 with light force. Due to the existence of magnetic attraction, this disassembly process is also easy and fast, without the need for any tools or additional force.

[0060] In some specific embodiments, the side wall of the mounting rod 210 is provided with a second spline 211, which not only enhances the structural strength of the mounting rod 210, but more importantly, provides a reliable basis for achieving stable cooperation between the mounting rod 210 and the mounting groove 322.

[0061] At the same time, the inner wall of the mounting groove 322 is also optimized to form a key groove that matches the second spline 211. When the mounting rod 210 is inserted into the mounting groove 322, a close fitting relationship is formed between the second spline 211 and the key groove. This fitting relationship not only ensures the stable positioning of the mounting rod 210 in the mounting groove 322, but more importantly, it effectively limits the rotational freedom of the mounting rod 210 during treatment.

[0062] In other words, even if the spatula 200 is subjected to forces from different directions during treatment, due to the close cooperation between the second spline 211 and the key groove, the mounting rod 210 will not rotate in the mounting groove 322, thereby ensuring that the relative position between the spatula 200 and the articulated ball 320 remains stable at all times. This design greatly improves the reliability and safety of medical devices during treatment, avoiding treatment errors or accidents caused by the rotation of the spatula 200.

[0063] In some specific embodiments, the outer side wall of the handle 100 is provided with anti-slip lines 120, which are not only regular in shape, evenly distributed, and moderately deep, but also provide sufficient friction to prevent slipping or dropping.

[0064] The design of the anti-slip lines 120 not only considers aesthetics, but more importantly, its practicality. In a wet or greasy environment, the anti-slip lines 120 can significantly enhance the friction between the handle 100 and the healthcare worker's hand, ensuring stable grip even in adverse conditions. In addition, the anti-slip lines 120 can also disperse hand pressure to some extent, reducing the fatigue of healthcare workers when holding for a long time.

[0065] In summary, by providing anti-slip lines 120 on the outer side wall of the handle 100, we have successfully improved the reliability and comfort of healthcare workers when holding the handle 100, providing a strong guarantee for the precise operation and long-term use of medical devices.
