Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a crown remover with adjustable angle. Background Art

[0002] In current oral treatment, it is very common to make a protective crown for a tooth with severe tooth tissue loss or that has undergone root canal treatment. Correspondingly, it is also common to need to remove the crown after encountering some special problems later.

[0003] At present, when a crown needs to be removed, medical staff often use a crown remover to remove it. However, conventional crown removers can only separate the connection between the crown and the tooth one by one, and due to the limitation of oral space, the crown removal process requires constant adjustment of the angle, and it is difficult for the tip of the crown remover to be completely located in the gap between the tooth and the crown. The whole process is cumbersome and inefficient. Summary of the invention

[0004] The utility model aims to provide an angle-adjustable crown remover, which solves the problem that conventional crown removers need to repeatedly adjust their positions to separate different connecting parts of teeth and crowns when removing crowns, which results in cumbersome operation; at the same time, it solves the problem that the crown remover is difficult to obtain the best angle when working due to the small oral space, resulting in low efficiency; the requirement for the patient's mouth opening is significantly reduced, thereby reducing the additional pressure and discomfort on the patient's teeth; the crown and tooth are separated at multiple locations simultaneously, and the angle is adjustable, thereby simplifying the entire crown removal process.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An angle-adjustable crown remover comprises a gripping rod and a crown removing device, characterized in that a striking head is fixedly arranged on the top of the gripping rod, a rotating shaft connecting portion is connected to the bottom of the gripping rod, the gripping rod is connected to the rotating shaft via the rotating shaft connecting portion, and the crown removing device is connected to the lower end of the rotating shaft.

[0007] A retaining groove is arranged at the lower side of the holding rod, and the retaining groove is provided with two card slots, one high and one low, for inserting the docking part of the retaining card; a plurality of retaining holes are arranged on the rotating shaft, and the retaining holes are used for inserting the end of the retaining card.

[0008] Furthermore, the crown removal device includes a crown portion, and the crown portion is connected to the lower end of the rotating shaft.

[0009] Furthermore, threaded screws are respectively provided on both sides of the tooth sleeve part.

[0010] Furthermore, the crown removal device also includes a crown removal hook, and the crown removal hook is fixedly connected to the socket part through the screw rod.

[0011] Furthermore, a latex pad with anti-slip stripes is arranged on the inner side of the lower end of the crown removing hook.

[0012] Furthermore, an inertia ring is sleeved on the holding rod.

[0013] Advantages of the utility model:

[0014] 1) The crown remover provided by the utility model has an adjustable angle function, allowing medical staff to adjust the angle of the crown remover according to the specific conditions of the patient, ensuring that the tip of the crown remover can be more accurately aligned with the gap between the crown and the tooth. This design significantly reduces the difficulty of operation caused by oral space limitations and improves the efficiency and safety of the crown removal process.

[0015] 2) By adjusting the angle, the crown remover significantly reduces the patient's mouth opening requirements, reducing the extra pressure and discomfort on the patient's teeth. In addition, the latex pad with anti-slip stripes can effectively increase the friction between the crown and the crown remover, maintaining stability, thereby reducing the pain and discomfort that may be caused to the patient during the operation.

[0016] 3) The new crown remover design allows simultaneous action on multiple points of the crown, and the pressure of each contact point is precisely controlled through the adjustable crown remover hook and screw, which not only ensures uniform force on the crown, but also greatly shortens the entire crown removal process. At the same time, this multi-point simultaneous action method is more effective than the traditional point-by-point separation method, and can safely remove the crown in a shorter time, especially in complex or difficult crown removal cases.
