Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The skull plugging device of the present embodiment includes the eccentric cylinder made of bone material (animal bone), and (off-centre operation is ellipse
Circle, i.e., close to round ellipse), the wherein end face of the eccentric cylinder formed with its integrally formed circular cover, it is circular
Formed with bar-shaped trough on cover plate, and formed with the graticule consistent with the long axis direction of eccentric cylinder.
The skull plugging device of the present embodiment realizes the closure to the perforate after the completion of skull operation, and activity bone flap is risen
Fixation, the scalp for avoiding tapping collapse, while protect the brain tissue of tapping not come to harm.Perforate is usual
Circular (directly being drilled with drill bit), when making eccentric cylinder, make its short axle close to or equal to perforate diameter, major axis is slightly
Slightly larger than the diameter of perforate, Camlock structure is formed, by major axis graticule alignment activity bone flap (due to the activity bone flap after cutting
The opening being slightly less than after cutting, skull plugging device can be placed in tune with perforate by major axis towards activity bone flap), by full dog point socket set
In the bar-shaped trough of knife alignment product, (positive and negative all can) angle is gently rotated, so as to which skull plugging device is locked in perforate,
It is set to be not easy to skid off.
People's bone has individual difference, and universal skull thickness B value in 5mm or so, i.e. Fig. 2 is generally 3.5~8.5mm.
Therefore, the thickness of skull plugging device is 3.5~8.5mm.Because the variable thickness of bone material surely reaches 6.5~8.5mm's
Thickness, therefore the skull plugging device of big specification needs to splice, and makes its thickness reach 6.5~8.5mm, for thickness be 3.5~
6.5mm skull plugging device then uses integral structure.

Middle end face forms circular cover；
Step S2, bar-shaped trough is formed in circular cover, and form the graticule consistent with the long axis direction of eccentric cylinder.
The skull plugging device step S1 spliced for needs includes：,
Step S11, make the first cylinder and the second cylinder respectively using bone material.In the present embodiment, first with milling machine system
Into the first cylinder and the second cylinder.
Step S12, dovetail groove is formed in the wherein end face of the first cylinder, and formed in the wherein end face of the second cylinder
Swallow-tail form is raised.Specifically process dovetail groove respectively on CNC milling machine and dove-tail form is raised.
Step S13, first cylinder and the second cylinder are assembled together by the dovetail groove and swallow-tail form projection,
To form whole cylinder.
Step S14, the whole cylinder spliced is processed into eccentric cylinder, and deviates from one end of dovetail groove in the first cylinder
Face forms circular cover, to form the eccentric cylinder being made up of the first sub- eccentric cylinder and the second sub- eccentric cylinder.
Wherein, step S14 is specifically included：The circumferentially rotary cutting, and cutting vertically since the end face of the second cylinder
Untill from the first cylinder other end preset distance, so as to form whole eccentric cylinder, and the circle of the first sub- eccentric cylinder
Cover plate.
In the present embodiment, (can be before S14, can also be after S14) also includes after S13：Screw is processed, and
The screwed hole through the first cylinder and the second cylinder is formed, screw is rotated in the screwed hole, and cuts screw protrusion
Part.Specifically, by the dovetail groove processed and dovetail tangs to connecting；To the whole cylinder connected, then add bit bore, attack
Silk；It is added in manufactured M4 screws fastening on numerically controlled lathe；Screw is stretched into unnecessary part to cut away.
