Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained without creative efforts belong to
The range of the utility model protection.
Fig. 1 is a kind of Medical bit structural schematic diagram that the utility model embodiment provides, and Fig. 2 is implemented for the utility model
A kind of radial schematic diagram for Medical bit that example provides, Fig. 3 are a kind of axis for Medical bit that the utility model embodiment provides
To schematic diagram, as shown in Figure 1 and Figure 2 comprising：Drill body 1 and the cutting blade for being set to 1 one end of the drill body
2。
The cutting blade 2 includes curvilinear sword line 21 and into knife face 22 and is moved back in 21 both sides of sword line
Knife face 23, the sword line 21 connect with the central axis 11 of the drill body 1 and the plane where the sword line 21 perpendicular to
The central axis 11 of the drill body 1, after Medical bit rotation, cutting blade 2 can drill through one vertically on bone
In the plane of the central axis 11 of the drill body 1, in follow-up drilling, can using the plane as the working face to drill,
The central axis for being used in the taper bit of drilling is vertical with the plane, and the taper bit used when to avoid drilling is because of taper
It is swung caused by the central axis of drill bit is not vertical with the estimated contact surface of bore position, and then improves borehole accuracy.
Specifically, in the present embodiment, the sword number of the cutting blade 2 is more than or equal to two-edged.Specific sword number can basis
The needs (bone hardness of the diameter, drilled position that such as drill) of drilling are selected, and the sword number of cutting blade 2 is preferably 3
Any one of sword, 4 swords, 5 swords, 6 swords (in Fig. 1 using the sword number of cutting blade be 6 swords as example).
Further, as shown in Fig. 2, the sword line 21 is in same plane, i.e. the sword line 21 of all cutting blades 2 is equal
In same plane.
On the other hand, when the sword number of cutting blade 2 is more than or equal to two-edged, shaft when being rotated due to Medical bit is to bore
The central axis of head ontology 1, therefore the cutting blade 2 can be uniformly distributed around the central axis 11 of the drill body 1,
It is specific as shown in Figure 3.
Fig. 3 is a kind of axial schematic diagram for Medical bit that the utility model embodiment provides, and plane shown in figure is
Plane where the sword line 21 of cutting blade 2.Six cutting blades that Fig. 3 includes, all sword lines 21 are met at a bit, the intersection point
On the central axis 11 of drill body 1, i.e., the described sword line 21 is connect with the central axis 11 of the drill body 1, and six
Bar sword line 21 is uniformly distributed around intersection point, to improve the precision of the plane drilled out.
Specifically, parallel with the central axis 11 of drill body 1 into knife face 22, it is understood that be into knife face 22 and sword line
Plane where 21 is vertical.
Specifically, since the plane where the sword line 21 of cutting blade 2 is perpendicular to the central axis 11 of drill body 1, because
This after rotation, Medical bit provided by the utility model can drill through a plane on bone.
During drilling through plane, due to curve-like sword line 21 make cutting blade 2 into knife face 22 and withdrawing face 23
Also curvilinear, and then reduce resistance when clast is discharged, to help bone bits to be smoothly discharged with the rotation of Medical bit.Into
One step, the curve-like can be parabolic shape.
Specifically, in the present embodiment, as shown in Figure 1, Medical bit further includes：Between the cutting blade 2 adjacent positioned at two
Chip pocket 3, chip pocket 3 is two adjacent cutting blades 2 into the groove between knife face 22 and withdrawing face 23, while described
Chip pocket 3 can limit drilling depth.
When Medical bit rotates, bone bits are discharged with the rotation of Medical bit from chip pocket 3, but flat what is drilled through
When face reaches certain depth, chip pocket 3, which fully enters, gets into the cave, and Medical bit provided in this embodiment not with chip pocket 3
Connected chip space causes bone bits that can not be discharged from chip pocket 3, therefore, when bone bits fill up chip pocket 3, can make bite
Sword 2 can not work on, and then Medical bit is made to be difficult to be further continued for deeply, to realize using provided in this embodiment medical
During bit bore, limiting device is not used, but drilling depth is directly limited in by safe range by chip pocket 3
It is interior.
Specifically, in the present embodiment, chip pocket 3 can be changed into the shape in knife face 22 and withdrawing face 23 by changing
Volume and depth, and then change to the limitation range of drilling depth.Specifically, as shown in Figure 1 and Figure 2, it is described into knife face 22 with
The central axis 11 of the drill body 1 is parallel, and the withdrawing face 23 can be curved surface.Further, as shown in Fig. 2, withdrawing
Face 23 can be recessed cambered surface, to increase the volume of chip pocket 3, and increase withdrawing face 23 and adjacent cutting blade 2 into
Angle between knife face 22, angle can facilitate after increasing carries out cleaning and aseptic process to the chip pocket 3 of Medical bit.It is alternative
, withdrawing face 23 or S type curved surfaces in the volume for increasing chip pocket 3 and conveniently to chip pocket 3 clean and sterile
While processing, the intensity of cutting blade 2 can also be increased.
Specifically, as shown in Figure 1, in the present embodiment, Medical bit can also include guide part 4, and the guide part 4 is used for
The Medical bit is limited to enter to bore path.
Guide part 4 can be arranged on drill body 1, and the diameter of guide part 4 can be more than the diameter of drill body 1.Or
Person, guide part 4 can be connect by card slot etc. with guider.
Guide part 4 can be other shapes or size, can also be connect by other means with guider, the present embodiment
Herein without limiting.
When drilling during surgery to bone, Medical bit provided in this embodiment can be used in estimated drilling first
Position drills out a plane as working face, then reuses taper bit in the prior art and drills on working face.
Due to having drilled out a plane as working face in advance, the central axis of taper bit can be made to hang down with contact surface
Directly, to be swung when avoiding drilling because the central axis of taper bit is not vertical with contact surface, and then practical brill is reduced
Hole site and it is expected that deviation between bore position, improves borehole accuracy.
The apparatus embodiments described above are merely exemplary, wherein the unit illustrated as separating component can
It is physically separated with being or may not be, some or all of module therein can be selected according to the actual needs
It achieves the purpose of the solution of this embodiment.Those of ordinary skill in the art are not in the case where paying performing creative labour, you can with
Understand and implements.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that：
It still can be with technical scheme described in the above embodiments is modified, or is carried out to which part technical characteristic etc.
With replacement；And these modifications or replacements, various embodiments of the utility model technology that it does not separate the essence of the corresponding technical solution
The spirit and scope of scheme.
