Abstract
The utility model provides a kind of skull repairing system.The skull repairing system, include the repairing main body of poly aryl ether ketone material shaping, the skull repairing system also includes being used for the butt strip for connecting the repairing main body and Preserve selef-cranium, and the butt strip is integrally formed with the repairing main body.Because the skull repairing system includes the butt strip for being used for connecting the repairing main body and Preserve selef-cranium, it is no longer needed for connecting repairing main body and Preserve selef-cranium with other connection members in operation, therefore skull repairing system use of the present utility model is more convenient.
Description
Technical field
It the utility model is related to a kind of human body implanted component, and in particular to a kind of skull repairing system.
Background technology
Cranioplasty is one of most common operation of neurosurgery, and its main purpose is to prevent brain tissue from damaging again
Wound, recover cranial cavity seal, treat skull defect syndrome.The research to skull repairing prosthese is concentrated mainly on titanium at present
On material, titanium is a kind of metallic element, and after skull repairing prosthese is made as, the skull repairing prosthese of titanium net is mostly a sheet of planar
The metal plate-like thing with higher hardness.In order that titanium net is completely covered damage location and reduces its sharp edges to pars affecta
The stimulation of position, conventional method are to reserve 1 cm or so at titanium net edge to cover bone window edge, still, after such titanium net implantation
Easily there is the problems such as alice, edge protuberance is exposed.In patent of invention CN103549990A, a kind of PEEK skull repairings are disclosed
Web plate, instead of titanium using PEEK materials has more preferable biocompatibility, and will not cause secondary damage to injured skull
Wound, but need in addition to connect repairing net and skull with connection sheet in surgical procedure, in-convenience in use.
The content of the invention
The purpose of this utility model in current technology is overcome skull repairing prosthese need when in use in addition with connection
Part connects skull repairing prosthese and Preserve selef-cranium so that skull repairing prosthese to be fixed, and inconvenient problem with use, carries
Skull repairing system a kind of easy to use and with good biocompatibility is supplied.
The purpose of this utility model is achieved by following technical solution：
A kind of skull repairing system, includes the repairing main body of poly aryl ether ketone material shaping, and the repairing main body is provided with
Butt strip, the butt strip, which has, to be used to connect the repairing main body and the extension of Preserve selef-cranium, and the butt strip is with repairing main body
It is integrally formed.
The repairing main body matches with the size, shape, radian of defects with skull bone window.
The poly aryl ether ketone material（PAEK）For polyether-ether-ketone (PEEK), PEKK (PEKK), polyether-ketone, polyether-ketone
In ether ketone ketone (PEKEKK) or polyether ether ketone ketone (PEEKK) any one or at least two mixture, preferably polyethers ether
Ketone (PEEK).
The poly aryl ether ketone material that the utility model uses has more preferable biocompatibility compared with titanium net, avoids gold
Belong to stimulation of the web plate to skull tissue, produce allergy, rejection, and it is artifact-free to have good intensity, toughness and imaging
Feature.The repairing main body is that the data gathered according to patient CT, MRI carry out the design that three-dimensional reconstruction completes personalization, so
It is made by 3D printing and/or machining mode, is matched completely with the shape, size, radian of defects with skull afterwards.Led with repairing
Body by integral forming also has the butt strip for being used for being connected with Preserve selef-cranium.The repairing main body and autologous cranium are connected with butt strip
Bone, it is no longer needed for connecting repairing main body and Preserve selef-cranium with other connector in operation, uses more convenient.
Preferably, mounting hole is preferably provided with the extension, so when operation, avoids the need for additionally opening again
Hole, directly skull repairing system can be fixed with screw.
Preferably, the thickness of the extension is 1.2 ~ 1.5 mm.
Preferably, the length of the extension is 8 ~ 10 mm, and the width of the extension is 4 ~ 9 mm.
Preferably, the edge of the extension is rounded edges.The design of rounded edges can be avoided because of sharp component pair
The damage that the possibility of skull or its hetero-organization is brought.
Preferably, the quantity of the butt strip is 3 ~ 6.Butt strip quantity is not limited in any way, and can be set according to being actually needed
It is fixed, can sufficiently stable fixed skull repairing system.
Preferably, the butt strip can be distributed uniformly or non-uniformly in around the repairing main body.
Design method between the butt strip and the repairing main body is including but not limited to following two.
One of which is that the extension of the butt strip is to be extended to be formed by the edge of the repairing main body.Using this scheme
When, it is necessary to first grind butt strip accommodating chamber on the relevant position of Preserve selef-cranium in cranioplasty surgery, then prolonging butt strip
Exhibition portion is placed in accommodating chamber.Because extension is to be extended to be formed by the edge of the repairing main body, therefore the skull repairing system
After system is fixed, the butt strip is embedded in Preserve selef-cranium, and extension and surrounding cranial bone are in smooth excessiveness, more attractive.
Another kind be the butt strip extension by located at it is described repairing body rim convex portion with repair main body be connected,
So that surface of the upper surface of the extension higher than the repairing main body.Under this design, the skull repairing system makes
Used time, the lower surface of the butt strip directly can be bonded with Preserve selef-cranium, can be not required to mill bone and are directly fixed, can simplify operation behaviour
Make.
The design method of butt strip described above, doctor can be selected according to being actually needed.
Preferably, the thickness of the repairing main body is 1 ~ 8mm.
Preferably, it is provided with through hole in the repairing main body.
It is highly preferred that the aperture of the through hole is 2 ~ 3 mm, through hole spacing is 10 ~ 15 mm.
The setting of through hole can be advantageous to the discharge of Cerebrospinal fluid, effectively reduce hypohydropses.
Compared with prior art, the utility model has following advantageous effects：
Skull repairing system provided by the utility model, according to patient's skull defect situation, produce and defects with skull
The repairing main body that shape, size, radian match, repairs main body and bone window fits like a glove.Skull repairing when butt strip is conveniently performed the operation
The fixation of system, it is no longer necessary to connect repairing main body and skull with other connection member.And the skull repairing system is
Make and be molded of PAEK material, there is good biocompatibility, avoid producing rejection phenomenon.
