Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
As depicted in figs. 1 and 2, the utility model provides a kind of model equipment of simulation Epidural cavity occupy-place compressing effect, packet
Include main fixator 100 and compression mechanism 200.Internal screw thread mounting hole is offered in the inside of the main fixator 100 (not show in figure
Out), the outer wall of the main fixator 100 is also installed with screw thread 110.The compression mechanism 200 includes compressing screw rod 210, and
It is fixed in the nut 220 of 210 top of compressing screw rod.The compressing screw rod 210 is spirally connected solid with mounting hole mutual cooperation
It is fixed, the grooving (not shown) of indent is offered in the middle part of the bottom surface of the compressing screw rod 210, be arranged in this grooving with
The protector 300 of the grooving clearance fit.The contact surface that the protector 300 is contacted with skull dural surface uses soft material
Material is made.
Using the above structure, compressing screw rod 210 is protruded into the skull window held successfully in advance, until being sleeved on compressing screw rod
300 surface of protector of 210 bottoms is contacted with dural surface.Then it utilizes on main 100 outer wall of fixator than sharp screw thread
110 edges smoothly screw in main 100 part of fixator fixed in skull window.In order to increase the stability of main fixator 100,
It can also be in the link position of main fixator 100 and skull window, with tissue glue and dental cement by gap closing.It can be manually rotated
Nut 220 can operate compressing screw rod 210 to be goed deep into skull window, to simulate Epidural cavity occupy-place compressing effect.In compressing
Compressing screw rod 210 is not directly contacted with dural surface in the process, and the contact surface of protector 300 is made of soft material again, so as to
To protect brain tissue not by coup injury, simulation compressing effect can continue to carry out.Meanwhile passing through main fixator 100 and compressing
The cooperation of mechanism 200 simulates Epidural cavity occupation time adjusting, and stability is more preferably.
As one of optional embodiment, in order to protect compression mechanism 200 not scratched by animal, in the main fixation
The upper surface of device 100 offers card slot (not shown), and protection cap 400 is connected in the card slot, thus will pressure
Compel mechanism 200 to cover.The hemispherical structure of the protection cap 400, and be made of soft silica gel material.The protection cap of this structure
400 surfaces are smooth, and reduction, which is accidentally touched, falls probability.Protection cap 400 can be removed, always adjust compressing screw rod 210 deeply, it can be achieved that
The pathophysiological process that simulation Epidural cavity occupy-place is gradually increased.
Screw thread on the compressing screw rod 210 is constant worm pich, and example can be set into the spacing between two adjacent threads
The specific numerical value of such as 0.5cm, 1cm stays in external thread turns by observation compressing screw rod 210, can substantially calculate compressing
Screw rod 210 protrudes into the depth in skull window, and staff is facilitated to grasp practical oppression.
The protector 300 is including support rod 310 and oppresses rubber head 320, the support rod 310 structure cylindrical, this
Support rod 310 is fixed in the upper surface of the compressing rubber head 320.The compressing rubber head 320 is made of soft rubber material.Branch
After strut 310 is inserted in grooving, when adjusting compressing screw rod 210, the upper surface of the bottom surface and compressing rubber head 320 of oppressing screw rod 210 is supported
It connects, and support rod 310 is and oppresses the grooving clearance fit in screw rod 210, therefore when screw rod 210 is oppressed in rotation, it can
It avoids that compressing rubber head 320 is driven to rotate.
The compressing rubber head 320 is in convex structure, and the circular arc radian of the compressing rubber head 320 of this convex structure is
60 °~120 °.The compressing rubber head 320 of this structure can be such that contact area increases, will not while realizing simulation compression
Coup injury dural surface.
As shown in figure 3, in another embodiment, the hemispherical structure of the compressing rubber head 320 can test different compressings
Influence of the area to brain tissue.
The above is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all benefits
The equivalent structure made by the utility model specification and accompanying drawing content is directly or indirectly used in other relevant technology necks
Domain, similarly within the scope of patent protection of the utility model.
