Detailed description of the invention
As shown in Figure 1 and Figure 2, this utility model automatic centering formula is ring-type takes the complete operation tool of bone drill, including T-shaped cutter 5,
Taking bone object 6 and detachable automatic centering formula is ring-type takes bone drill, wherein, the ring-type bone drill that takes of detachable automatic centering formula includes ring-type
Hollow drill bit 1, connecting portion 3, the heart is bored 4 and the ring-type brill handle 2 that is connected with rotating driving device, at circular hollow
The front end of drill bit 1 is provided with band saw dentation blade, and the rear end of circular hollow drill bit 1 is connected with one end of connecting portion 3,
The other end of connecting portion 3 is connected with ring-type brill handle 2, the heart bores 4 and includes boring handle 42 to heart drill bit with to the heart,
The rear end that the heart bores 4 drill bits is connected with to heart brill handle 42, the heart is bored handle 42 and is detachably arranged in connecting portion 3
On, the heart is bored the axis of axis and circular hollow drill bit 1 of 4 on same straight line, the heart is bored 4 chisel edges at ring
Shape hollow drill bit 1 front end is outside or the heart bores 4 front ends with circular hollow drill bit 1 front end at grade.
As shown in Figure 6, Figure 7, T-shaped cutter 5 is T-shaped cutter 5 conventional in prior art dental operation, also known as T-shaped brill,
End vertical at drilling rod 51 is provided with a disk drill bit 52, is provided with cutting tooth 53 at the edge of disk drill bit 52.
As shown in Figure 8, take bone object 6 described in and take bone object 6 for what prior art was commonly used.The described size taking bone object 6 should be with
The detachable ring-type size taking bone drill of automatic centering formula matches.
The heart is bored 4 design with circular hollow drill bit 1 concentric bore, it is ensured that the thickness of ring-type bone and center；Removable
Unloading design, can dismantle internal to heart brill 4 after ensureing concentric locating, the endoporus being drilled can play centralized positioning effect.
As shown in Figure 4, Figure 5, it can be some drill bit 41, fluted drill drill bit 43 or cortex bone drill that the heart bores 4 drill bits
Drill bit.
To the heart bore handle 43 for standard dental rotation apparatus footstalk bar portion, corresponding connecting portion 3 be with to the heart
Bore the standard cell phone connection handle that handle matches.The heart is bored the standard that handle 43 is standard GB/T 5046.1-85 defined
Dentistry rotates the footstalk bar portion of apparatus.The standardized design of connecting portion 3 can install multiple brill, fluted drill or cortex
Bone drill, improves range of application of the present utility model.Multiple drill bit can be changed during using.
As it is shown on figure 3, the external diameter of connecting portion 3 is more than the diameter of ring-type brill handle 2, the external diameter of connecting portion 3 is less than ring-type
The external diameter of hollow drill bit 1.
Further, observe the location that the heart is bored 4 for convenience, the sidewall of circular hollow drill bit 1 is provided with multiple length
Square peephole.Multiple peepholes can uniform be arranged on the sidewall of circular hollow drill bit 1.Preferably, at circular hollow
3 rectangle peepholes it are laid with on the sidewall of drill bit 1.A length of circular hollow drill bit 1 length of peephole
0.5-0.8, the width of peephole is the 0.5-0.8 of circular hollow drill bit 1 diameter.So can not either affect surgical staff
Sight line ensure that again the intensity that circular hollow drill bit 1 is enough.
Distance between front end and place, the circular hollow drill bit 1 front end plane of some drill bit 41 is 1-5mm.The most right
When the heart bores 4 sites brill, the position of some drill bit 41 is positioned at the outside of place, circular hollow drill bit 1 front end plane, is using
Time, first boring location with point, emplacement depth is 1-5mm, and then circular hollow drill bit 1 just starts to bore.So it can be avoided that ring
Shape hollow drill bit 1 is in use subjected to displacement, it may appear that take ring-type bone inner and outer wall not with one heart, bone wall thickness not
The most even take the phenomenons such as bone is imperfect.
Distance between front end and the circular hollow chisel edge place plane of fluted drill drill bit is 0-5mm.
Circular hollow drill bit 1 rear end is provided with annular joint face, and the internal diameter of annular joint face is more than the internal diameter of connecting portion 3, ring
The edge of shape joint face is connected with circular hollow drill bit 1 rear end, and the end, one end of connecting portion 3 is connected with annular joint face
Connect.
The other end of connecting portion 3 is provided with end face, and the end face of connecting portion 3 other end is connected with the end face of ring-type brill handle 2.
Circular hollow drill bit 1, connecting portion 3 and ring-type brill handle 2 can weld together after processing respectively, it is also possible to for
It is integrally machined and forms.
The work process of this example: by bore or fluted drill to the heart bore handle 42 be installed to connecting portion 3, by ring-type brill hands
Handle 2 is installed on rotating driving device, and some drill bit 41 or fluted drill drill bit 43 turn with circular hollow drill bit 1 simultaneously
Dynamic, center is pinpointed, pierces about 1mm under bone in circular hollow drill bit 1 front end, pull down and the heart is bored 4, then with ring-type
Hollow drill bit 1 is taken out after continuing to be drilled into desired depth, pulls down and ring-type takes bone drill, loads onto the T-shaped cutter 5 of appropriate size, be put into
Ring-type bone inwall, selects suitable rotating speed to circle along the ring-type manual dextrorotation of bone inwall, stops the rotation, by T-shaped cutter 5
Position is moved to center, takes out T-shaped cutter 5, is placed into above ring-type bone with taking bone object 6, after position is put well, pushes down
Ring-type articular cortex, to not having the side of draw-in groove firmly, moves away from parent by ring-type bone, takes out ring-type bone.
Above an embodiment of the present utility model has been described in detail, but described content be only of the present utility model relatively
Good embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range
Impartial change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
