Description
Technical field
The utility model is related to a kind of bone ring cutting brill, it is mainly used in the tool brill for promoting operation outside dentistry maxillary sinus, is belonged to
In the field of medical instrument technology.
Background technology
Currently, when carrying out promoting operation outside maxillary sinus during tooth-implanting, bone ring cutting use is carried out, used tool is
Metal zigzag bone ring cutting bores, and as described in Fig. 1, is cut to alveolar bone using bone ring cutting brill, when sawtooth cuts through alveolus
After bone, being easy to encounter maxillary sinus film makes maxillary sinus film be damaged.
Utility model content
The utility model is to overcome above-mentioned technical problem, and provide a kind of bone ring cutting brill, can effectively be prevented in cutting tooth
The phenomenon that slot bone mistiming damages maxillary sinus film.
The technical scheme in the invention for solving the above technical problem is：A kind of bone ring cutting brill, including drillstock and tubular
Drill bit, one end of the drillstock is equipped with the department of assembly of connection drilling machine, and the cylinder of the drill bit, which is equipped with, takes bone mouth, described
The external contacting surface of drillstock and drill bit detachable connection, the drill bit bottom is equipped with the smooth silicon carbide layer in bottom surface.Using this kind
The zigzag of existing drill bit bottom is changed to cut using the smooth silicon carbide layer in bottom surface by technical solution, and by drillstock and
Drill bit is set as detachable connection, can select the drill bit or drillstock of different size model as needed, can when cutting alveolar bone
Preferably control depth of cut, and the flatness cut is also higher, the phenomenon that further effectively preventing from damaging maxillary sinus film.
Further, further include nut in the utility model, the upper top surface of the drill bit is equipped with mounting hole, the drillstock
The other end is equipped with boss portion, fixed part and interconnecting piece successively, and the interconnecting piece is external thread structure, and one end of the drillstock passes through
The mounting hole is simultaneously threadedly coupled by the nut portion of being connected thereto, and the fixed part is connected with the mounting hole, described convex
The radius in platform portion is more than the radius size of the mounting hole.In actual use due to the utility model, drill bit is in high speed and revolves
Turn state, using this kind of connection type, drill bit and drillstock stable connection are not in loosen the phenomenon that skidding, and dismantle installation
It is convenient.
Further, it is hexagonal hole in the mounting hole of the utility model.
The utility model is compared with the prior art, and is had the advantages that：The utility model is simple in structure, and design is closed
Reason, installation is relatively simple with dismounting, and compared with the prior art, the silicon carbide layer hardness that the utility model uses is higher, and cuts essence
Degree and cutting hardness are also higher, and detachable connection between drill bit and drillstock can select the brill of different size model as needed
Head or drillstock further preferably control depth of cut and flatness.
Description of the drawings
Fig. 1 is the structural schematic diagram that prior art bone ring cutting bores.
Fig. 2 is the structural schematic diagram of the utility model.
Fig. 3 is the decomposition diagram of the utility model.
Fig. 4 is the drill bit overlooking structure diagram of the utility model.
In attached drawing：1 is drillstock, and 11 be department of assembly, and 12 be boss portion, and 13 be fixed part, and 14 be interconnecting piece, and 2 be drill bit, 21

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment, and following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Referring to Fig. 2-Fig. 4, the present embodiment includes drillstock 1, drill bit 2 and nut 3, and drillstock 1 and drill bit 2 are detachable connection
Structure.
One end of drillstock 1 is equipped with the department of assembly 11 of connection drilling machine, and the other end of drillstock 1 is equipped with boss portion successively
12, fixed part 13 and interconnecting piece 14, interconnecting piece 14 are external thread structure.
Drill bit 2 is tubular structure, is equipped in the cylinder of drill bit 2 and takes bone mouth 21, and the external contacting surface of 2 bottom of drill bit is equipped with bottom surface
Smooth silicon carbide layer 22.It is equipped with the mounting hole 23 of regular hexagon in the upper top surface of drill bit 2.
One end of drillstock 1 passes through mounting hole 23 and is connected thereto portion 14 by nut 3 and is threadedly coupled, fixed part 13 and fixation
Hole 23 is connected, and the radius of boss portion 12 is more than the radius size of mounting hole 23.
Above example has made more detailed description to the utility model, but these descriptions are not to this practicality
Novel limitation, i.e. the utility model are not limited to the concrete structure and description of above-described embodiment.The protection of the utility model
Range includes that those obviously convert or substitute and retrofit to those skilled in the art.
