Abstract
The utility model discloses a dental crown dismounting clamp. A handle is arranged on one side of the hinged point of the dismounting clamp, and a jaw is arranged on the other side of the hinged point and can be expanded along with the kneading of the handle; and a wedge-shaped expansion block is arranged in each of expanding directions of the end of the jaw. The dental crown dismounting clamp is simple in structure and convenient to use.
Description
Technical field
This utility model relates to the medical device of dental field, in particular, relates to the aid of removing the corona cover.
Background technology
When if the corona cover needs to remove, need usually to break out slight crack with broken hat car pin one at corona cover jaw face, lingual surface, buccal surface, again the corona cover is extractd, but between corona cover and the tooth adhesives is arranged, extract quite difficulty.
The utility model content
Technical problem to be solved in the utility model is to realize a kind of instrument that can conveniently remove the corona cover after broken hat car pin is with corona cover cutting slight crack.
To achieve these goals, the technical solution adopted in the utility model is: the corona cover is removed pincers, and this dismounting pincers pin joint one side is handle, and opposite side is jaw, described jaw is expanded with the kneading of handle, and described jaw end respectively is provided with the expansion piece of a wedge shape along dimension.
Described handle and jaw integrally bending are curved.
Be provided with return spring between described handle, described return spring is under stress not, and two expansion pieces of jaw are overlapping.
Described expansion piece end angle is the 30-60 degree.
Described decreased food is more than three times of jaw length.
It is simple, easy to use that advantage of the present utility model is that this corona cover is removed wrench structure.
Description of drawings
Below the content of every width of cloth accompanying drawing expression in this utility model description and the labelling among the figure are made brief description:
Fig. 1 removes view for mediating pliers with the corona cover;
Fig. 2 jaw when not mediating can be filled in corona cover slight crack view; (
Fig. 3 removes pincers user mode sketch map for the corona cover;
Fig. 4 removes side schematic view for the corona cover;
Labelling among the above-mentioned figure is: 1, hands handle; 2, jaw; 3, expansion piece; 4, return spring; 5, corona cover.
The specific embodiment
Referring to Fig. 1-3 as can be known, it is handle 1 that the corona cover is removed pincers pin joint one side, and opposite side is jaw 2, and the jaw 2 of these dismounting pincers is expanded with the kneading of handle 1, and the interface point place is provided with position-limit mechanism, and making the corona cover remove pincers can only be by merging phase to expansion state.Respectively be provided with the expansion piece 3 of a wedge shape along dimension in jaw 2 ends, the preferred 30-60 degree of its wedged gap, as shown in Figure 3, filling in corona under two expansion piece 3 coincidence status overlaps 5 gaps (this moment, interface point was in spacing initial point state, restriction dismounting pliers grip can only be mediated and make the jaw expansion, and handle can not be expanded), when the expansion piece 3 of wedge shape is mediated at handle 1, embed the gap of corona cover 5 and tooth, thereby peel off corona cover 5 easily.Simultaneously, as shown in Figure 4, it is curved with jaw 2 integrally bendings that corona cover is removed the handle 1 of pincers, is convenient to the doctor and will hands handle 1 and jaw 2 is stretched into carry out the corona cover in the patient oral cavity and remove.
For making equipment easy to use, as shown in Figure 2, be provided with return spring 4 on 1 on handle, this return spring 4 is under stress not, two of jaw 2 expansion pieces 3 are overlapping, are convenient to the doctor and will remove pincers and put into patient's corona and overlap 5 gaps, and while handle 1 length is more than three times of jaw 2 length, to strengthen the leverage of removing pincers, the convenient corona cover 5 of removing.
By reference to the accompanying drawings the present invention has been carried out exemplary description above; obviously this utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving design of the present invention and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
