Technical Field

[0001] The utility model relates to the technical field of dental tools, in particular to a protective dynamic pressure crown remover for porcelain teeth. Background Art

[0002] In restorative dentistry, porcelain teeth are a common restoration method that uses porcelain materials to cover the tooth surface to repair tooth defects and improve tooth color and shape. However, due to the strong adhesion between porcelain teeth and teeth, when porcelain teeth need to be removed, traditional removal tools are often inconvenient to operate and easily damage teeth or porcelain tooth surfaces. Therefore, it is particularly important to develop a tool that can remove porcelain teeth conveniently, quickly and safely.

[0003] Most of the crown removers on the market are designed with a simple lever principle. Although they can meet the needs of removing porcelain teeth to a certain extent, there are still many shortcomings in the actual operation process. For example, when traditional crown removers clamp porcelain teeth, the connection structure between the clamping part and the handle is not stable enough, which may easily cause the porcelain teeth to fall off or be damaged during the crown removal process. In addition, traditional crown removers usually require doctors to continuously apply a large operating force when in use, which not only consumes too much physical strength of the doctor, but also makes it inconvenient for the doctor to operate when continuously applying force, which increases the difficulty of the doctor's operation.

[0004] In view of the above problems, the utility model document proposes a protective dynamic pressure crown remover for porcelain teeth. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1

[0027] Reference Figure 1-4 , crown remover, including:

[0028] The protective dynamic pressure crown remover for porcelain teeth is mainly composed of a crown remover body 1, which is further subdivided into a first clamp body 2 and a second clamp body 3. The first clamp body 2 includes a first clamp part 4, a first rotating part 5 and a first handle 6, while the second clamp body 3 includes a second clamp part 7, a second rotating part 8 and a second handle 9. The first rotating part 5 and the second rotating part 8 are combined by a rotational connection to realize the combination of the first clamp body 2 and the second clamp body 3. This rotational connection allows the two clamp bodies to rotate relative to each other when necessary, thereby changing the distance between the clamping parts.

[0029] In order to realize auxiliary rotation and positioning between the two pliers bodies, a connecting plate 14 is introduced in this embodiment. The connecting plate 14 is not only used to connect the two pliers bodies, but also realizes the adjustment and fixation of the relative positions of the two pliers bodies through its specific structural design.

[0030] Specifically, a first groove 10 is provided at the bottom of the first handle 6, and a rotating groove 11 is provided on the top inner wall of the first groove 10. A rotating rod 15 is rotatably connected to the top inner wall of the rotating groove 11. The bottom of the rotating rod 15 is fixedly connected to the connecting plate 14, and the rotating rod 15 is located at one end close to the connecting plate 14. Such a design enables the rotating rod 15 to drive the connecting plate 14 to rotate.

[0031] Similarly, a second groove 12 is provided at the bottom of the second handle 9, and a slide groove 13 is provided on the top inner wall of the second groove 12. The slide groove 13 runs through the top of the second handle 9. A limit rod 17 is fixedly installed on the top of the connecting plate 14. The limit rod 17 is located at the end of the connecting plate 14 away from the rotating rod 15. One end of the limit rod 17 runs through the slide groove 13 and slides with the inner wall of the slide groove 13. This sliding fit design allows the connecting plate 14 to be connected to the first pliers body 2 and the second pliers body 3 by sliding the limit rod 17 in the slide groove 13 when the first handle 6 and the second handle 9 rotate relative to each other.

[0032] In order to ensure that the first handle 6 and the second handle 9 can remain in an open state when not affected by external force, a torsion spring 16 is provided on the outer wall of the rotating rod 15, one end of the torsion spring 16 is fixedly connected to the top of the connecting plate 14, and the other end is fixedly connected to the top inner wall of the rotating groove 11. The torsion spring 16 provides a continuous rotation force for the connecting plate 14, thereby realizing the continuous open state of the first handle 6 and the second handle 9, the first clamping part 4 and the second clamping part 7.

[0033] In order to fix the position of the limit rod 17 in the slide groove 13 and avoid the situation where the user needs to press and apply force for a long time when using it, the outer wall of the limit rod 17 is provided with a thread, and a fixing nut 18 is threadedly connected thereto. The fixing nut 18 is located above the second handle 9 and cooperates with the top of the second handle 9. By tightening the fixing nut 18, the position of the limit rod 17 in the slide groove 13 can be fixed.

[0034] In addition, the present application can be used in the field of dental tool technology and can also be used in other fields suitable for the present application.

[0035] Example 2

[0036] refer to Figure 1 , 2 3. Improvement on the basis of Example 1: A protective dynamic pressure crown remover for porcelain teeth, which is applied to the field of dental tool technology;

[0037] In addition, in order to improve the user's gripping experience and increase the friction between the fixing nut 18 and the second handle 9 , the outer walls of the first handle 6 and the second handle 9 are both provided with a rubber layer.

[0038] Finally, in order to ensure that the first clamping part 4 and the second clamping part 7 have a good clamping effect on the porcelain tooth, anti-slip grooves are provided on the side where the two are tightly attached to each other. The design of such anti-slip grooves not only increases the friction between the clamping part and the porcelain tooth, but also effectively prevents the porcelain tooth from slipping and being damaged during the crown removal process.

[0039] The working principle and use process of the present technical solution are as follows: when in use, the user can use the crown remover body 1 to clamp the patient's porcelain tooth so as to complete the corresponding crown removal later; when the crown remover body 1 is in use, since the connecting plate 14 is continuously subjected to the torsion force of the torsion spring 16, the connecting plate 14 will continuously rotate in one direction, and then through the sliding of the limit rod 17 in the slide groove 13, the connecting plate 14 will continuously abut against the first clamp body 2 and the second clamp body 3 to separate, which can ensure that the first clamping part 4 and the second clamping part 7 are continuously in the open state, so that the user can use it at any time; when the user holds the crown remover body 1 and completes the clamping of the patient's porcelain tooth, the user The fixing nut 18 can also be turned to rotate and gradually approach the connecting plate 14. After rotation, the fixing nut 18 will clamp the second handle 9 with the connecting plate 14. As the friction between the connecting plate 14, the fixing nut 18 and the second handle 9 increases, the fixing nut 18 can fix the position of the limit rod 17. At this time, the distance between the first handle 6 and the second handle 9 is fixed, and the first clamping part 4 and the second clamping part 7 at the other end will be maintained in a fixed clamping state. The user does not need to continuously press the first handle 6 and the second handle 9, which is more labor-saving and convenient for the user to complete the crown removal operation of the porcelain tooth.
