Abstract
The utility model relates to a cranio-maxillofacial bone plate which is a plate body. The shape of the plate body can be changed according to different use portions, the plate body is provided with a plurality of through holes, the through holes are kidney-shaped, the upper half portion of each through hole is provided with a step, and the bottom face of each step is a curved surface in smooth transition. According to the cranio-maxillofacial bone plate, by means of changing of the structure of the through holes, after threaded sections of screws are connected with a bone in a threaded mode, the tail portions of the screws make contact with the steps, and then the bone plate is connected with the bone; besides, the screws can continue to be screwed, due to the fact that the tail portions of the screws abut against the bottom faces, in smooth transition, of the steps, the screws slide in the kidney-shaped through holes, and accordingly the bone can slightly move, and growth of a new bone at a fracture portion of the bone is facilitated. In addition, the surface of the cranio-maxillofacial bone plate is provided with a hydroxyapatite coating, and hydroxyapatite is a main component of human body bone tissue. After the cranio-maxillofacial bone plate is implanted into a human body, calcium and phosphorus are disassociated from the surface of a material and are absorbed by body tissue, and new tissue can grow.
Description
Technical field
This utility model relates to the internal fixation implantation instrument in medical apparatus and instruments, particularly relates to a kind of cranium jaw face blade plate.
Background technology
Cranium jaw face blade plate is fixing for cranium maxillofacial fracture.The cranium jaw face blade plate using at present, be generally a plate body, the shape of plate body changes according to different use positions, on plate body, be disposed with several through holes, screw is located in through hole, and after the thread segment of screw is threaded with skeleton, the afterbody of screw is spacing by through hole, and plate body is fixed on skeleton, realizes being fixedly connected with between the skeleton of fracture.But the fracture of skeleton, in recovery process, if fracture remains on a fixing state always, is just unfavorable for the growth of new skeleton, is unfavorable for the rehabilitation of fracture.
Utility model content
Technical problem to be solved in the utility model is: the cranium jaw face blade plate that a kind of new bone growth of the fracture that can promote skeleton is provided.
For addressing the above problem, the technical solution adopted in the utility model is: cranium jaw face blade plate, it is a plate body, the shape of plate body changes according to different use positions, on plate body, be disposed with several through holes, described through hole is long waist shaped, and the first half of through hole is provided with step, the curved surface that the bottom surface of step is smooth transition.
The outer setting of described plate body has hydroxyapatite coating layer.
The beneficial effects of the utility model are: above-mentioned cranium jaw face blade plate, it is simple in structure, easy to use.By changing the structure of through hole, after the thread segment of screw is threaded with skeleton, the afterbody of screw contacts with step, realize being connected of blade plate and skeleton, and can be by continuing to screw screw, screw is due to the conflict of the step bottom surface of afterbody and smooth transition, and screw slides in the through hole of long lumbar hole, thereby can make skeleton occur displacement slightly, be beneficial to the growth of the new skeleton of the fracture of skeleton.In addition, its surface is provided with hydroxyapatite coating layer, and hydroxyapatite is that skeleton is organized main component.After implanting, calcium and the phosphorus material surface that can dissociate is absorbed by bodily tissue, and the tissue that makes new advances of growth.
Accompanying drawing explanation
Figure l is structural representation of the present utility model;
Fig. 2 is the plan structure schematic diagram of through hole in figure l;
Fig. 3 is the sectional structure schematic diagram of through hole in Fig. 2;
In figure: l, plate body, 2, through hole, 3, step.
The specific embodiment
Below by specific embodiment, cranium jaw face blade plate described in the utility model is described in further detail.
As shown in Figure l, cranium jaw face blade plate, be a plate body l, the shape of plate body l changes according to different use positions, on plate body l, be disposed with several through holes 2, as shown in Figure 2 and Figure 3, described through hole 2 is long waist shaped, the first half of through hole 2 is provided with step 3, the curved surface that the bottom surface of step 3 is smooth transition.
As preferred version, the outer setting of described plate body l has hydroxyapatite coating layer.Hydroxyapatite is that skeleton is organized main component.After implanting, calcium and the phosphorus material surface that can dissociate is absorbed by bodily tissue, and the tissue that makes new advances of growth.
Above-mentioned cranium jaw face blade plate is by changing the structure of through hole 2, after the thread segment of screw is threaded with skeleton, the afterbody of screw contacts with step 3, realize being connected of blade plate and skeleton, and can be by continuing to screw screw, screw is due to the conflict of step 3 bottom surfaces of afterbody and smooth transition, and screw slides in the through hole 2 of long lumbar hole, thereby can make skeleton occur displacement slightly, be beneficial to the growth of the new skeleton of the fracture of skeleton.
The above embodiments are principle and effect thereof of illustrative the invention only, and the embodiment of part utilization, but not for limiting this utility model; It should be pointed out that for the person of ordinary skill of the art, not departing under the prerequisite of this utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
Claims (2)
1. cranium jaw face blade plate, is a plate body, and the shape of plate body changes according to different use positions, on plate body, be disposed with several through holes, it is characterized in that: described through hole is long waist shaped, and the first half of through hole is provided with step, the curved surface that the bottom surface of step is smooth transition.
2. cranium jaw face blade plate according to claim 1, is characterized in that: the outer setting of described plate body has hydroxyapatite coating layer.
