Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of tooth-planting positions drill bit.
Background technology
Tooth-planting operation is first to be punched on the alveolar ridge of missing tooth, then Implant.During dental implant surgical,
For round bur to position implanted region, destruction surface layer cortex bone enables follow-up each stage drill bit that can pierce deep layer bone tissue easily, but
In the presence of it is partially sliding easily when the high-speed rotation the shortcomings that；Trigone brill pinpointing ability is strong, but presence can not easily be cut due to the strength that drills is small
The shortcomings that cortex of bone.
Doctor needs to constantly change surgical instrument during punching, and process is complicated；Therefore presently used instrument cannot be very
The good demand for adapting to clinical practice operation.
Utility model content
The technical issues of the utility model is mainly solved present in the prior art, provides a kind of tooth-planting spitting drill
Head.
The specific technical solution of the utility model is as follows：
A kind of tooth-planting positions drill bit, including drillstock；The drillstock rear end is provided with what is connect with tooth-planting mobile phone
Connecting portion；It is characterized in that：The drillstock front end is disposed with round bur except interior and trigone is bored；The drillstock, round bur and
The central shaft that trigone is bored is same straight line；It is positive triangular pyramid that the trigone, which is bored, and bottom surface is connect with round bur.
As preference：A diameter of 1.5-3mm. of the round bur
As preference：The height that the trigone is bored is 1-3mm.
As preference：The contact surface of the drillstock and round bur is that outer profile is round, a diameter of 1-2.5mm, and small
In round bur diameter.
As preference：The bottom surface that the trigone is bored is the equilateral triangle that the length of side is 1mm.
The technical solution of the utility model is ingenious in design, easy to operate, can complete to drill to alveolar ridge downwards simultaneously and
The operation of side cutting, the lower position bored of accurate control and angle；The type of drill bit used in doctor is advantageously reduced simultaneously, is simplified
Surgical procedure.
The utility model has the following advantages that：
（1）The utility model its trigone drilling row positional punch, while round bur can bore game clock layer cortex bone in operation；
Since the power that trigone is bored compares concentration, pinpointing ability is strong, so in drill process, round bur is not easy to slide partially, easy to operate, safety
Coefficient is high, while completes the operation punched downwards to alveolar ridge and side is cut；Doctor is avoided when using round bur to occur partially
Sliding danger improves medical efficiency and plantation drilling effect；
（2）Drill bit has certain diameter, so before drilled hole polishing starts, moves drill bit, drill bit is made to be positioned over conjunction
Suitable near and far and cheek tongue direction position, facilitates doctor accurately to be operated in tooth-implanting region.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the bottom view of the utility model；
In figure, drillstock 1, connecting portion 2, trigone brill 3, round bur 4.
Specific embodiment
The utility model is described further with reference to embodiment and attached drawing.
A kind of tooth-planting positions drill bit, including drillstock 1；1 rear end of drillstock is provided with to be connect with tooth-planting mobile phone
Connecting portion 2；It is characterized in that：1 front end of drillstock is disposed with round bur 4 except interior and trigone bores 3；The drillstock 1,
The central shaft that round bur 4 and trigone bore 3 is same straight line；It is positive triangular pyramid that the trigone, which bores 3, and bottom surface is connect with round bur 4；Its
Middle drillstock 1 and round bur 4, round bur 4 and trigone 5 coupling part areas of brill are as larger as possible, if coupling part area is inadequate
The mechanical strength of the drill bit can be influenced, coupling part is easily wrecked.
A diameter of 1.5-3mm. of round bur 4 in the present embodiment
The height that trigone bores 3 in the present embodiment is 1-3mm.
It is round, a diameter of 1-2.5mm, and less than ball that the contact surface of drillstock 1 and round bur 4, which is outer profile, in the present embodiment
Bore 4 diameters.
The bottom surface that trigone bores 3 in the present embodiment is the equilateral triangle that the length of side is 1mm.
The positioning drill bit mainly includes drillstock 1 and the round bur 4 positioned at 1 front end of drillstock is bored with the trigone for being fixed in the round bur
3；The central shaft that the drillstock 1, round bur 4 and trigone bore 3 is same straight line.
Round bur 4 is the spherical blade of a diameter of 1.5-3mm, and the drillstock 1 is connect with the top of round bur 4, the lower half of round bur 4
Sphere centre（Bottom）Protrusion is provided with trigone and bores 3, and trigone bores the triangular pyramid of 3 a height of 1-3mm；The round bur 4 and described three
The contact surface that rib bores 3 is the equilateral triangle that the length of side is 1mm.
During concrete application, on the alveolar ridge for preparing to plant tooth, mucous membrane and periosteum are cut, removes mucoperiosteum valve, exposure alveolus
Ridge top determines the position of tooth-implanting, and the trigone that will plant positioning drill bit bores and is directed at the position, and by drillstock long axis and adjacent teeth long axis
It is parallel, slightly to alveolar ridge pressuring direction, tooth-planting mobile phone is driven, tooth-planting is made to position bit, and constantly spray water, i.e.,
The operation of the downward punching and side cutting to alveolar ridge can be completed simultaneously.Occur partially when using round bur so as to avoid doctor
Sliding danger and the problem of can not bore cortex of bone when using triangular pyramid；Be conducive to doctor and use the less drill bit of type
Drilling operation can be completed.
Although this specification has more used drillstock 1, connecting portion 2, trigone bores 3, and 4 grade terms of round bur are not precluded
Use the possibility of other terms.The use of these items is only for more easily describing the essence of the utility model, it
To be construed to any one of the additional limitations be all contrary to the spirit of the present invention.
In above-mentioned technical proposal, the structure that connecting portion, round bur, trigone are bored is the prior art.
It should be understood that the part that this specification does not elaborate belongs to the prior art.
It should be understood that the above-mentioned description for preferred embodiment is more detailed, can not therefore be considered to this
The limitation of utility model patent protection domain, those of ordinary skill in the art are not departing under the enlightenment of the utility model
Under the ambit that the utility model claims are protected, replacement or deformation can also be made, each falls within the utility model
Within protection domain, the utility model is claimed range and should be determined by the appended claims.
