The advantages of present invention obtains and good effect are:
1, this fixing clamp is provided with lock, inner teeth road, external teeth road and fixinig plate and when in use protrudes into fixinig plate
In the drilling bored when opening cranium, then external teeth road is moved to suitable position along sutura with fixinig plate, then will latch to cranium
The position of bone sets movement, when at the suitable position that lock is moved to skull, at this point, by inner teeth road and external teeth road jail on lock
It is engaged and installed in firmly together, at this moment, is cut using routine operation and cut the external teeth road outside lock, which makes
Used time does not need to be completely covered using mating setting tool, easy to operate, skull gap, is not easy to keep bone flap or bone fragment prominent
Out, it loosens, deform；Since the inner teeth road of the fixing clamp can be removably engaged and installed in together with external teeth road,
If there is complication, the fixing clamp may be reused and take out it is extremely convenient, have great clinical meaning.
2, inner teeth road and internal framework, when fixed, the inner card cage in inner teeth road are provided in the lock of this fixing clamp
It can carry out coincideing with the exterior bayonet slot in external teeth road well and engage, form multiple identical points, Cranial-bone-flap or bone fragment and skull
Between connection it is stronger；External teeth road after internal framework can will be cut out is pressed into wherein, prevents the external teeth road after cutting out
Injury to scalp tissue；In addition, buckle structure can be designed according to human skull's radian, aesthetic effect is enhanced.
3, the shape in the external teeth road of this fixing clamp can be designed according to the width of sutura, effective over sutura, and
It can reasonably be detected according to skull thickness, make fixed effect more preferably.
4, the fixinig plate of this fixing clamp can be placed in skull close to meninx side, well with skull by Cranial-bone-flap or bone fragment
It is fixed in same plane or same cambered surface, had not only played good fixed effect, but also there is good aesthetic effect.
5, without using extra auxiliary tool when this fixing clamp uses, only needing routine operation to cut can be carried out operating, and make
With conveniently, operating time is greatly reduced.
Detailed description of the invention
