Description
Technical field
The present invention relates to the field of medical instrument technology more particularly to epiphysis grinding heads and epiphysis sander.
Background technique
If the bone stump after amputation is without polishing, surface is sharp keen, is easy to cause to damage to peripheral vessels and tissue.
However, sander is all directed to cortex in the inner part and designs, it is impossible to be used in the polishing of lateral cortex.Currently, operative doctor is all to use
File carries out hand file, and to polish sharp position, the polishing time is long, and large labor intensity, bruting process is be easy to cause
Damaging surrounding tissue, grinding effect are also undesirable.
Summary of the invention
The present invention is intended to provide epiphysis grinding head and epiphysis sander, can polish to bone stump, grinding efficiency is improved,
Labor intensity is reduced, grinding effect is improved.
In order to achieve the above objectives, The technical solution adopted by the invention is as follows:
Epiphysis grinding head, including knife handle, cutter hub and blade, the knife upper end are connect with cutter hub, and the blade is mounted on
Cutter hub top surface, the cutting edge of the blade are located at the top surface of blade, and cutting edge is arranged radially, and cutting edge outer end is higher than inner end, cut
It cuts and is recessed into smooth arc shape in sword；Blade at least there are two, blade is provided at circumferentially spaced around the axis of knife handle.
Further, blade is arranged at equal intervals around the axis of knife handle.
Further, blade has 4-8.
Preferably, blade has 6.
Further, the cutter hub top surface is equipped with locating shaft, and locating shaft is coaxial with knife handle.
Further, blade tip is higher by the top of locating shaft.
Preferably, the height of locating shaft is 60mm-70mm, and the height of blade is 35mm-50mm.
Wherein, cutter hub is cylinder, and cutter hub is coaxial with knife handle.
Further, cutting edge extends to blade tip from the lower end of blade from inside to outside.
Preferably, the radius of cutting edge is 60mm-65mm.
Epiphysis sander further includes motor, knife handle is operably mounted at motor other than including above-mentioned epiphysis grinding head
On.
In use, the present invention is mounted on motor or electric drill by knife handle, locating shaft is then inserted into bone stump again
Pulp cavity in, and blade is made to be located at bone stump periphery, starts motor or electric drill, blade carries out circular motion, then that bone is residual
End polishes smooth.
Compared with prior art, the invention has the following advantages:
The present invention can polish to bone ends, improve grinding efficiency, shorten operating time, reduce labor intensity, and
And the smoothness of polishing is good, can avoid causing to damage to peripheral vessels and tissue.Bone stump after being particularly suitable for polishing amputation.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing, to the present invention into
Row is further described.
Embodiment one
As shown in Figure 1-3, epiphysis grinding head disclosed in the present embodiment, including knife handle 1, cutter hub 2 and blade 3,1 upper end of knife handle
It is connect with cutter hub 2, blade 3 is mounted on 2 top surface of cutter hub, and the cutting edge 31 of blade 3 is located at the top surface of blade 3, and cutting edge 31 is radial
Setting, 31 outer end of cutting edge are higher than inner end, are recessed into smooth arc shape in cutting edge 31；Cutting edge 31 is from inside to outside under blade 3
End extends to 3 top of blade.Blade 3 at least there are two, blade 3 around knife handle 1 axis it is equally circumferentially spaced.
The number of blade 3 is rationally arranged as needed, and usually, blade 3 has 4-8 to be advisable.Preferably, blade 3 has 6
It is a.
For convenience of positioning centering, 2 top surface of cutter hub is equipped with locating shaft 4, and locating shaft 4 and knife handle 1 are coaxial, and 4 top of locating shaft is high
3 top of blade out.In use, locating shaft 4 is first inserted into pulp cavity, positioning centering is carried out.Blade 3 is sheet, knife in the present embodiment
Piece 3 is parallel with the axis of knife handle 1.
Embodiment two
The present embodiment designs the size of epiphysis grinding head.In the present embodiment cutter hub 2 be cylinder, cutter hub 2 with
Knife handle 1 is coaxial.The height of locating shaft 4 is 60mm-70mm, diameter 8mm.The height of blade 3 is 35mm-50mm, cutting edge 31
It is inside recessed into smooth arc shape, the radius of the arc is 60mm-65mm, such as 64.9mm.
The diameter of cutter hub 2 is 70mm-100mm, is highly 10mm.The height of blade 3 is that the half of 2 diameter of cutter hub is advisable.
If the length of knife handle 1 is that 80mm blade 3 is sheet, with a thickness of 5mm.
Embodiment three
The difference between this embodiment and the first embodiment lies in: as shown in Figure 4,5, cutter hub 2 is not sheet in the present embodiment, but
It is gradually thinning from the bottom up, become most thin to the position of cutting edge 31.2 bottom of cutter hub is thick, can increase the intensity of cutter hub, adjacent
There is the chip space 5 being arranged radially between two cutter hubs 2.
