As shown in figs. 1-7, in a specific embodiment of the utility model, a kind of bone drill, including drilling rod 1 and linkage are set
Set the drill bit assembly on 1 head of drilling rod；The drill bit assembly includes the spitting drill 2 and use for positioning for the drilling rod 1
In the cutting burr 3 of cutting sclerotin, the cutting burr 3 is arranged in 2 periphery of spitting drill.It is arranged by linkage on 1 head of drilling rod
Spitting drill 2 and cutting burr 3 so that can either be positioned when cutting sclerotin, and be able to carry out sclerotin cutting, and
The periphery of spitting drill 2 is arranged in cutting burr 3, so that the positional accuracy of spitting drill 2 is higher more stable, so that ability of feeling relieved is good,
It can be further ensured that drilled edge without chipping, mitigates patient suffering when carrying out sclerotin drilling.The wherein use not office of bone drill
It is limited to electronic form or manually form, since the periphery of spitting drill 2 is arranged in cutting burr 3, then cutting burr 3 and positioning
Bore between 2 can there are certain gaps to consider to be worth doing for accommodating the bone that cuts away, can not also there are cut away for accommodating
The gap of bone bits, as long as can guarantee that spitting drill 2 can position, cutting burr 3 can be cut, in addition, for spitting drill 2
Specific structure without limitation, as shown in figure 5, can be taper positioning, can be cylindrical positioning, can be infundibulate positioning,
As shown in fig. 6, being also possible to spiral shape, as long as positioning action can be played, the specific structure of cutting burr 3 is not also done
It limits, can be annular cutting burr 3, can be square cut and bore 3, be also possible to rectangle cutting and bore 3, as long as cutting can be played
The effect of sclerotin.
In another specific embodiment of the utility model, the central axis of the drilling rod 1, spitting drill 2 and cutting burr 3
It is overlapped.Stability when bone is bored in order to further increase, so that the central axis phase mutual respect of drilling rod 1, spitting drill 2 and cutting burr 3
It closes, so that the center of entire bone drill is more steadily stablized all in same horizontal line, when so that boring bone.
In another specific embodiment of the utility model, as shown in Fig. 2 or 3 or 4,2 front end of spitting drill with
The linear distance on 1 head of drilling rod is greater than or equal to the linear distance of 3 front end of cutting burr and 1 head of drilling rod,
So that the bit part of spitting drill 2 is concordant or slightly longer with the bit part of cutting burr 3, in this case, can guarantee advanced
Row positioning carries out cutting sclerotin again, or is positioned and cut simultaneously, so that cutting is more accurate while more stable,
It is further ensured that drilled edge without chipping.
In another specific embodiment of the utility model, as shown in Figures 4 and 5, the spitting drill 2 includes being used for as institute
The positioning end 5 of the positioning of drilling rod 1 and the cutting edge 6 for cutting sclerotin are stated, the positioning end 5 is set to the center of the drilling rod 1
On line, cutting edge 6 is set to the two sides of the positioning end 5.What needs to be explained here is that the concrete shape and quantity of positioning end 5 are not
Be specifically limited, can be taper, be also possible to it is rectangular, can also be rectangle and one or more, as long as can position i.e.
Can, the cutting edge 6 of 5 two sides of positioning end is cooperated to make spitting drill 2 also be able to carry out cutting sclerotin while positioning
The cutting of cutting burr 3 so that sclerotin cutting it is more stable, while cutting burr 3 carries out cutting sclerotin pass through spitting drill 2
Cutting edge 6 polishing skeletonization bits are carried out to sclerotin, guarantee cut edge while positioning without chipping, but also cutting is more thin
It causes.As shown in Figures 6 and 7, the shape for cutting edge 6 and quantity setting are not specifically limited, and can be designed according to the different needs
The diversified forms such as diamondwise face or gore and rectangular surfaces, multiple quantity, as long as can serve the same role,
In, as shown in Figure 7, positioning end 5 is used to position for drilling rod 1, and for cutting sclerotin, the both ends of cutting edge 6 are provided with cutting edge 6
For cutting the cut surface 8 of sclerotin, when drilling rod 1 is when carrying out rotation cutting sclerotin, positioning end 5 helps drilling rod 1 to be determined
, for the cut surface 8 on cutting edge 6 for cutting sclerotin, it is two that wherein cut surface 8, which is preferable to provide, is of coursed, can also root
Multiple cut surfaces 8 are arranged in both ends according to demand cutting edge 6 again, as long as can reach identical technical effect.
In another specific embodiment of the utility model, as shown in Figure 1, the cutting burr 3 includes and the drilling rod 1
Cut surface 8 of the cutting wall 7 of head connection with cutting 7 front end of wall is arranged in and for cutting sclerotin, along the cutting
The multiple cutting teeths being circumferentially arranged in face 8, the cutting wall 7 setting in 2 periphery of spitting drill, the cutting wall 7 with it is described
The bone for accommodating bone bits is formed between spitting drill 2 considers receiving portion to be worth doing.The shape of cutting burr 3 is optimized in the present embodiment, excellent
It is selected as the cutting burr 3 of tubular, wherein the periphery of spitting drill 2 is arranged in cutting wall 7, is enclosed in spitting drill 2 such as tubular structure
Outside, while the bone bits receiving portion formed between wall 7 and spitting drill 2 for accommodating the sclerotin cut down or bone bits is cut, this
In it should be noted that sclerotin and bone bits do not do specific differentiation, do not limit specific diameter shape, the shape of cutting teeth and
Number is also not specifically limited, as long as being able to carry out cutting sclerotin reaches identical technical effect, in the positioning of positioning end 5
Under, cutting teeth can generate a large amount of bone bits by cutting sclerotin, and bone bits receiving portion can accommodate the bone bits of generation.
In another specific embodiment of the utility model, it is used for as shown in figure 3, being additionally provided on the cutting wall 7
The chip-removal hole 9 of bone bits is discharged.The sclerotin that cutting burr 3 generates during being cut can enter in bone bits accommodating chamber, but
If being that bone bits are excessive, the rotation that can consider spitting drill 2 in accommodating chamber to be worth doing to bone generates obstruction, to influence the normal work of spitting drill 2
Make, by be arranged chip-removal hole 9, can make bone bits accommodating chamber in sclerotin with cutting burr 3 and spitting drill 2 rotation and from
It is discharged in bone bits accommodating chamber, so that spitting drill 2 and/or cutting burr 3 can continue to work normally.
It further include connection ring 4 in another specific embodiment of the utility model, the drill bit assembly passes through the company
Ring 4 is connect to connect with 1 head of drilling rod.On the one hand the stability that drill bit assembly is connected with 1 head of drilling rod is increased, on the other hand
Also certain mark and restriction are carried out to the drilling depth of bone drill, improve the safety of bone drill drilling.
In conclusion the bone drill of the utility model, centering ability is good, and drilled edge mitigates patient suffering and knot without chipping
Structure is simple.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
