Generally, the dental elevator is composed of three parts: blade, handle and rod. The dental elevator has different specifications and shapes according to different tooth extraction needs.

[0003] The utility model patent with patent application number CN202320933635.1 discloses a minimally invasive dental extraction elevator with the function of disassembling and replacing the head, including a handle, the handle is a structure of being narrow at the top and wide at the bottom, the front and rear parts of the outer surface of the handle are both provided with notches, the front part of the outer surface of the handle is movably connected with a front tensioning mechanism, the rear part of the outer surface of the handle is movably connected with a rear tensioning mechanism, and the rear tensioning mechanism has the same structure as the front tensioning mechanism. The structure utilizes the front tensioning mechanism and the rear tensioning mechanism to improve the use of the dental elevator, increase the convenience of operation, and facilitate the disassembly and replacement of the working head.

[0004] However, when this structure is actually used, the working head of the dental extraction elevator needs to extend to the position of the gums and the teeth, so the working head of the dental extraction elevator is relatively sharp. In addition, there is a lack of a protective structure at the working head of the dental extraction elevator, which causes the working head to accidentally touch the gums of other teeth when it is inserted into the patient's mouth, causing discomfort to the patient. Moreover, once the dental extraction elevator falls, the working head may contact the ground, accelerating the wear of the working head. In view of this, the utility model proposes a minimally invasive dental extraction elevator. Utility Model Content

[0016] As attached Figure 1-4 The minimally invasive tooth extraction elevator shown comprises a working head 1 and a handle 2 , wherein the working head 1 is mounted on the top of the handle 2 .

[0017] Specifically, in this structure, the dental extraction elevator used for minimally invasive tooth extraction is composed of a working head 1 and a handle 2. One end of the working head 1 is used to extend into the patient's oral cavity and is located at the tooth that needs to be extracted. The handle 2 is taken by medical staff and is used to operate the working head 1 inside the patient's oral cavity. The working head 1 has various specifications and shapes according to needs, which are not considered too much in the present utility model.

[0018] In this embodiment, as shown in the attached Figure 1 , 2 As shown in Figures 3 and 4, a protective structure is provided on the outside of the working head 1, and the protective structure includes a protective sleeve 3, which is sleeved on the surface of the working head 1. Slide grooves 4 are provided on the front and rear surfaces of the handle 2, and guide rods 5 are provided inside the two slide grooves 4. A guide block 6 is provided on the outside of the guide rod 5, and a pull plate 7 is provided on the surface of the guide block 6. The number of pull plates 7 is set to two, and the two pull plates 7 are symmetrically distributed and fixedly installed on the corresponding surfaces of the guide blocks 6. The guide blocks 6 are slidably connected on the outside of the guide rod 5, and an extrusion spring 8 is provided on the outside of the guide rod 5 at the bottom of the guide block 6. A plurality of anti-slip arc grooves 9 are provided on the surface of the pull plate 7, and an L-shaped connecting rod 10 is fixedly installed on the pull plate 7, one end of the L-shaped connecting rod 10 is connected to the protective sleeve 3, the inner diameter of the protective sleeve 3 is larger than the outer diameter of the working head 1, the protective sleeve 3 is slidably connected on the outer surface of the working head 1, and the protective sleeve 3 is made of rubber material.

[0019] Specifically, the protective structure in the structure can protect the working head 1 to prevent the tooth extraction rod from falling to the ground and causing wear of the working head 1. At the same time, it can reduce the possibility that the working head 1 accidentally touches other parts of the tooth to be removed, such as the gums, when it is inserted into the patient's oral cavity.

[0020] In the initial state, a protective sleeve made of rubber is arranged at the top position of the working head 1. At this time, the tip of the working head 1 is wrapped by the protective sleeve, which can reduce the wear of the working head 1 caused by the dental lifter falling to the ground, and reduce the collision of the tip of the working head 1 with the fragile part of the gums of the patient's mouth.

[0021] The medical staff clasps the two pull plates 7 with their fingers and puts the palm against the lower end of the handle 2, so that the handle 2 can be used in a T-shape, which is convenient for the medical staff to operate. When it is necessary to extend one end of the working head 1 to the position where the patient needs to extract teeth, the palm is pressed against the lower end of the handle 2, and the two pull plates 7 are slid downward with the fingers. At this time, the guide block 6 can slide outside the guide rod 5 inside the slide groove 4 and squeeze the extrusion spring 8. In the process of extending the pull plate 7 downward, it can drive the protective cover to slide downward outside the working head 1 through the L-shaped connecting rod 10, so that the working part of the working head 1 is exposed, and then the working head 1 can perform tooth extraction on the patient. In this process, when the working head 1 is not in the patient's tooth extraction position, the protective cover outside the working head 1 is still in a wrapped state, thereby reducing damage to other parts of the patient's oral cavity;

[0022] If the medical staff accidentally drops the tooth extraction elevator, the extrusion spring 8 will reset after losing the extrusion, so that the pull plate 7 will reset, and then the L-shaped connecting rod 10 will drive the protective sleeve to return to the original position outside the working head 1. At this time, the protective sleeve outside the working head 1 is in a wrapped state, which has a protective effect on the working head 1 and reduces the wear of the working head 1 caused by falling to the ground.

[0023] Working principle of this utility model:

[0024] When the above structure is used, the medical staff clasps the two pull plates 7 with their fingers, and puts the palm against the lower end of the handle 2, extends one end of the working head 1 to the position where the patient needs to extract the tooth, and after finding the exact position for tooth extraction, puts the palm against the lower end of the handle 2, and uses the fingers to slide the two pull plates 7 downward;

[0025] At this time, the guide block 6 can slide outside the guide rod 5 inside the slide groove 4 and squeeze the extrusion spring 8. During the downward extension of the pull plate 7, it can drive the protective cover to slide downward outside the working head 1 through the L-shaped connecting rod 10, so that the working part of the working head 1 is exposed, and then the working head 1 can perform tooth extraction operation on the patient.

[0026] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
