Embodiment 1

[0036] This embodiment relates to the structure of the device, combined with Figure 1-3 A metal stud removal device for dental prosthetics, characterized in that it includes an industrial control cabinet 1, a display screen 2, an image control module 3, an opener 4, an operating handle 5, and a control pedal 6;

[0037] The industrial control cabinet 1 is connected with the operating handle 5 and the control pedal 6. The operating handle 5 is provided with a chuck and an ultrasonic transducer, and the metal pile 7 is clamped by the chuck, and the metal pile is loosened by the ultrasonic vibration of the ultrasonic transducer before being removed;

[0038] The display screen 2 is connected to the image control module 3, and the image control module 3 is connected to the gag 4. The gag 4 is provided with a camera 41 with multiple lighting functions, and the image control module 3 controls the image taken by the camera 41 on the gag 4 to be displayed on the display. on screen 2....

Embodiment 2

[0056] The present embodiment relates to the specific method of use of the device, specifically as follows:

[0057] First place the gag in the mouth, adjust the angle of the camera, and illuminate and shoot the position that needs to be operated;

[0058] The image displayed on the display device is selected through the display control module, one image can be displayed, and multiple images can also be selected to be displayed;

[0059] Remove the crown of the tooth at the operation position, and leak the metal post. For different metal posts, you can choose different operation methods.

[0060] For shorter metal stakes, the operating handle can be directly clamped on both ends of the metal stake, and then the ultrasonic vibration can be started to make the metal stake loose under the drive of ultrasonic vibration, and then it can be taken out;

[0061] For longer and thinner metal piles that leak out, you can use the drill bit of the operating handle to be fixed at one posi...

Abstract

The invention relates to a metal post pin removing device for the department of prosthodontics. A special mouth gag is designed, illumination and shooting in multiple directions can be provided, and operation of dentists is greatly facilitated; an operating handle is provided with an ultrasonic transducer, and the transducer can perform ultrasonic oscillation, so that a metal post is loosened under ultrasonic vibration and is easier to take out; the integrated operation handle is arranged, the side wall of the metal post can be perforated during vibration, ultrasonic contact efficiency is improved after perforation and operation time is shortened; multiple functions of perforation, grinding, clamping and ultrasonic vibration can be achieved by one operating handle, multiple types of operation can be conducted for different metal posts, efficiency of taking out the metal posts is greatly improved, and damage is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a device for removing metal studs in the department of dental restoration. Background technique [0002] A post crown is a full crown restoration that uses a metal post crown inserted into the root canal for retention. The length of the post crown should be sufficient, generally required to reach 2 / 3 to 3 / 4 of the root length, or about the same length as the completed crown; the thickness of the post crown is about 1 / 3 of the transverse diameter of the root surface. The shape of the post crown should be tapered, tapering towards the apex. The cross-section of the post crown should be consistent with the shape of the root, which is conducive to retention. [0003] Sometimes the patient's treatment requires removal of the old metal post. The metal piles are generally very firmly combined, and the hardness is very high, so they cannot be directly drilled and ground. However, th...
