Description
Technical field
This utility model relates to medical instruments field, is specifically related to gingival forming device.
Background technology
In tooth-implanting operation, in implantation body's secondary operation stage, need to excise the part mucoperiosteum that implantation body covers nut surface, to lay gingiva plastotype base station.When excision implantation body covers the part mucoperiosteum of nut surface, conventionally adopt circular trephine excision.Because circular trephine is a hollow cylinder, its otch is circular, so the otch forming on gingiva can only be used in conjunction with the general moulding base station of cylindrical gingiva, the gingiva forming is like this different from the oval or round triangle outward appearance of natural teeth cervical region, and after artificial tooth has been installed, thereby easily cause gingival margin position change to expose hat metal edge, produce the shortcomings such as black triangle that tooth faces gap, have a strong impact on attractive in appearance.In addition, circular trephine, when excision mucoperiosteum, need to connect air motor, and this not only easily makes patient produce the feared state of mind, and can increase medical treatment cost.
Summary of the invention
The object of this invention is to provide a kind of gingival forming device, do not need to be connected with air motor use, manually can with excision mucoperiosteum, excision mucoperiosteum cutting knife can from gingiva mucoperiosteum, eject, be conducive to alleviate doctor's operation process, alleviate patient's misery.
A gingival forming device, comprises sleeve pipe, connecting rod, spring, column mucosa groove and cutting knife, and the sealing of described column mucosa groove one end, the other end offer hollow cavity, and the opening of described column mucosa groove is connected with cutting knife; The blind end of described column mucosa groove is connected with connecting rod, and on described connecting rod, cover has spring, and the upper end of described spring is fixed on connecting rod, and described spring is located in sleeve pipe, and the lower ending opening diameter of described sleeve pipe is less than spring outer diameter.
Described cutting knife is hollow columnar, is provided with cross-sectional area diminishing hollow cavity from top to bottom in described cutting knife, and described cutting knife lower end is provided with the oval edge of a knife.
In described column mucosa groove, in hollow cavity and cutting knife, the cross section of hollow cavity is oval.
Two sections of elliptic arcs that the described oval edge of a knife is symmetrical in its major axis upwards cave in respectively curved.
Symmetrically on described column mucosa groove offer several holes.
The upper end of described connecting rod is provided with gland.
Beneficial effect:
While adopting this utility model gingival forming device excision gingiva mucoperiosteum, elasticity due to spring, the cutting knife of excision mucoperiosteum can eject from gingiva mucoperiosteum, be conducive to shorten doctor's operation process, especially the patient who simultaneously performs the operation for a plurality of positions, can greatly simplify operating difficulty, alleviate patient's misery.For same patient, can in the situation that retaining sleeve pipe, according to the difference of tooth position, change mucosa groove and the cutting knife of different model.Because the edge of a knife of cutting knife is oval-shaped, so the otch cross section forming on gingiva is also oval-shaped, more approach the form of natural teeth cervical region, on this otch, artificial tooth is installed, can reduce to greatest extent the black triangle that tooth faces gap.In column mucosa groove, in hollow cavity and cutting knife, the cross section of hollow cavity is oval, and excision gingiva mucoperiosteum is more laborsaving.In addition, two sections of elliptic arcs that are symmetrical in its major axis due to the oval edge of a knife of the present utility model upwards cave in respectively curved, the shape of a saddle cross section of such structure and gingival mucosa and its below alveolar bone norma sagittalis is suitable, is easy to easily excise mucoperiosteum, alleviates corrective surgery misery.Hole on mucosa groove, is conducive to the soft tissue of cutting to be rejected, and is beneficial to continue to use after next cleaning and sterilizing.This utility model gingiva cuff molding device does not need to be connected with air motor use, manually can with excision mucoperiosteum, can not make patient produce the feared state of mind, reduce medical treatment cost.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model, 1-sleeve pipe wherein, and 2-spring, 3-column mucosa groove, 4-cutting knife, 5-gland, 6-Spring Card, 7-connecting rod, the oval edge of a knife of 8-, 10-refers to hold up portion.
Fig. 2 be the B of Fig. 1 to view, 3-column mucosa groove wherein, the oval edge of a knife of 8-.
Fig. 3 is the cutaway view of another optimal way of this utility model, 1-sleeve pipe wherein, and 2-spring, 3-column mucosa groove, 4-cutting knife, 5-gland, 6-Spring Card, 7-connecting rod, the oval edge of a knife of 9-, 10-refers to hold up portion.
The specific embodiment
By reference to the accompanying drawings 1,2 and Fig. 3 the technical solution of the utility model is described.
As illustrated in fig. 1 and 2, gingival forming device, comprises sleeve pipe 1, connecting rod 7, spring 2, column mucosa groove 3 and cutting knife 4, and the 3 one end sealings of column mucosa groove, the other end offer hollow cavity, and the opening of column mucosa groove 3 is connected with cutting knife 4; The blind end of column mucosa groove 3 is connected with connecting rod 7, and on connecting rod 7, cover has spring 2, the upper end of spring 2 to be fixed on the Spring Card 6 of connecting rod 7, and spring 2 is located in sleeve pipe 1, and the lower ending opening diameter of sleeve pipe 1 is less than spring 2 external diameters.
The cross section of column mucosa groove 3 interior hollow cavities and cutting knife 4 interior hollow cavities is oval, adapts like this with the oval edge of a knife, makes to excise gingiva mucoperiosteum more laborsaving.
Symmetrically on column mucosa groove 3 offer several holes, convenient the mucoperiosteum of excision is disposed.
The upper end of connecting rod 7 is provided with gland 5, and lower end and the connecting rod of gland 5 are suitable, and the diameter of upper end is greater than casing inner diameter.
In the outside of sleeve pipe upper end, be provided with and refer to hold up portion 10, described finger to hold up portion 10 for symmetrically arranged two projections, for finger locating, be more conducive to exert pressure on gland.
As shown in Figure 3, two sections of elliptic arcs that the oval edge of a knife is symmetrical in its major axis upwards cave in respectively curved preferred technical scheme.Because so the oval edge of a knife of shape and the shape of a saddle shape of gingiva cross section are suitable, so doctor's accurate positioning, more laborsaving while excising mucoperiosteum, patient suffering can be alleviated.
During operation, the cutting knife of this utility model gingival forming device is positioned over to gingival surface, then compresses gland and cutting knife is pressed downward to and excised mucoperiosteum.Unclamp gland, cutting knife outwards ejects in mucoperiosteum, and now cut mucoperiosteum will be taken out of, is embedded in column mucosa groove, in the hole on mucosa groove side, easily rejects.
