Description
Technical field
The present invention is related to and belongs to medical apparatus and instruments manufacturing field, is related to repair for the filling of skull hole and Cranial-bone-flap resets admittedly
Fixed device, specially a kind of fixing device for the filling of drill for craniotomy hole and preparation method thereof.
Background technology
Neurosurgery operation of opening cranium needs the suitable position drilling on skull using drill for craniotomy (such as pneumatic drill or electric drill),
Then Cranial-bone-flap is separated using supporting miller for craniotomy knife, then carries out the lesion resection of skull lower floor, then needed skull
Lobe carries out replacement and fixation, and the little defect of poroid or other shapes of skull caused because of drill for craniotomy can be also remained after replacement and fixation.Pin
The fixed demand resetted to Cranial-bone-flap and the reparation demand of the little defect of skull, the solution of clinician can be existing according to hospital
Product select fixed or repair mode.For example select titanium connection sheet and titanium nail to carry out the fixation of reset Cranial-bone-flap, need supporting
Instrument twists screw, and operation is relatively not easy enough, and screw is shot skull and has damage in various degree, if child patient titanium material is produced
Product are often avoided, and nuclear-magnetism inspection can be affected after titanium material implants in addition.Bone hole or sutura after Cranial-bone-flap is resetted
Reparation demand brings a new difficult problem to doctor, and usual doctor has to select the broken bone or medical collagen of some residuals extra large
Silk floss is used cooperatively, and in addition to skeletonization effect on driving birds is not good, increased the risk of infection on the contrary.Certainly, with indivedual artificial bones
Clinical practice, different degrees of solve the problems, such as Bone Defect Repari, but or artificial bone hardness is exactly greatly very much too crisp, almost
Without toughness, so being difficult to moulding, and the immunologic rejection risk of potential animal derived materials.
The content of the invention
In order to solve the above problems, the present invention provides a kind of fixing device for the filling of drill for craniotomy hole and its making side
Method, it is easy to use, safe effective, in addition to it can reach the stability of fixed reset Cranial-bone-flap, it is also possible to different degrees of rush
Enter defect of skull position new bone tissue to be formed, reach reconstruction.
The present invention is adopted the following technical scheme that：
A kind of fixing device for the filling of drill for craniotomy hole, the thick rivet shape of fixing device generally class of drill for craniotomy hole filling
Shape, including the edge of a knife one, the edge of a knife two, the edge of a knife three, vertical component and horizontal component；The horizontal component is convex surface arc, described to hang down
Straight part is cylinder；Horizontal component is horizontally disposed with, and vertical component is vertically arranged, the coaxial one of horizontal component and vertical component into
After type, horizontal component and vertical component are coaxially integrally formed, the penetrating cutting of horizontal direction are carried out to vertical component and forms gap, stitched
Gap forms the edge of a knife one, the edge of a knife two and the edge of a knife three.
After the horizontal component and vertical component are coaxially integrally formed, penetrating cutting are carried out to vertical component and forms " Lv " word
Capitiform, " well " font, " X " font, " two " font or " three " font gap.
