Abstract
The utility model discloses a skull implanting plate and belongs to the technical field of neurosurgery clinical speciality. The skull implanting plate is characterized by comprising a polymethylmethacrylate layer and two layers of alloy nets formed by Ti alloy wires; the two layers of alloy nets are arranged in the polymethylmethacrylate layer in parallel; wefts and warps of each layer of alloy net form angles of 60 degrees; warps of the two layers of alloy nets are coincided and the wefts of the two layers of alloy nets are not coincided under the overlook projection; the distances between the parallel net wires of each layer of alloy net are 16-20mm. Compared with the prior art, the skull implanting plate has the characteristics of better strength and high reliability.
Description
Technical field
This utility model relates to a kind of plate of implanting, and particularly a kind of skull is implanted plate.
Background technology
Cranioplasty is the common hands art of neurosurgery, at present, this type of operation of great majority is all used artificial skull to replace the skull at disappearance position, the most frequently used artificial skull material is exactly titanium alloy web plate, along with the raising of people's living standard, people not only will can reach dissection by skull repairing, physiological recovery, requirement to outward appearance beauty treatment is also more and more higher, for repairing body and chimeric more perfect of the former skull of patient, reconstruction operations be previously generally by doctor in the preoperative or in art according to the size and shape of patient's defect, strike by hand titanium alloy web plate processed, on patient's head, repeatedly repair type after relatively, cut seam, until meet the requirement of patient's defect, finally be screwed, this life of will seeking medical advice must produce as early as possible dummy according to the damaged shape of patient's skull on operating-table, but because the shape of each patient's skull defect is all different, repair materials titanium alloy web plate is difficult for being shaped, in art, need repeatedly moulding, this has just increased operating time, although the appearance of three-dimensional titanium plate is easier to the ratio of moulding change, shortened operating time, but its hardness is not as two-dimentional titanium plate.And the temperature conduction of titanium alloy web plate is stronger, be subject to the impact of ambient temperature and cause patient's intracranial discomfort, titanium alloy reticulated panel edges is sharp keen, and the complication such as scalp pain easily occur after the thinner operation in patients of scalp, and titanium alloy reticulated panel edges is scratched scalp can cause that cerebrospinal leak even infects.
Utility model content
Technical assignment of the present utility model is for above the deficiencies in the prior art, provides a kind of skull to implant plate.
The technical scheme in the invention for solving the technical problem is: a kind of skull is implanted plate, it is characterized in that: comprise the alloy network that polymethyl methacrylate layer and two-layer titanium alloy line form, described two-layer alloy network is set in parallel in polymethyl methacrylate layer inside; The warp of every layer of alloy network all becomes 60 ° of angles with parallel, and under downward projection, the warp of two-layer alloy network overlaps, and parallel does not overlap, and the distance between the parallel netting twine of described every lamination gold is 16mm ~ 20mm.
Distance between the parallel netting twine of above-mentioned every layer of alloy network is 18mm.
Compared with prior art, the utlity model has following outstanding beneficial effect.
1, the cooperation of polymethyl methacrylate layer and alloy stratum reticulare increases the intensity of whole skull implantation plate, dual fail-safe, and reliability is high.
2, the nearly human body skin of polymethyl methacrylate laminating, is not subject to the impact of ambient temperature, and effective titanium alloy reticulated panel edges is sharp keen, and the problem of the complication such as scalp pain easily occurs after the thinner operation in patients of scalp.
3, mesh is large, can fixing bone pin, increase whole skull and implant the intensity of plate, and net, apart from large, can see through X-ray, facilitates the inspection of intracranial disease situation.
4, the design of double-layer alloy net, guaranteeing that morphotropism is good, easily moulding, shorten in the situation of operating time, increased the intensity of hone lamella, the appearance that has alleviated medical worker's labor intensity and post-operative complication simultaneously.
Accompanying drawing explanation
Fig. 1 is this utility model side-looking section partial structurtes schematic diagrams.
Fig. 2 overlooks partial structurtes schematic diagram after the stack of this utility model double-layer alloy net.
The specific embodiment
Below in conjunction with specification drawings and specific embodiments, this utility model is further illustrated.
As shown in Figure 1, this utility model comprises the alloy network 2 that polymethyl methacrylate layer 1 and two-layer titanium alloy line form, and described alloy network 2 is set in parallel in polymethyl methacrylate layer 1 inside.
The warp of every layer of alloy network 2 all becomes 60 ° of angles with parallel, as shown in Figure 2, under downward projection, the warp of two-layer alloy network 2 overlaps, and parallel does not overlap, and the distance between the parallel netting twine of described every lamination gold is 16mm ~ 20mm, mesh is large, can fixing bone pin, nail both can be used for fixing two-layer alloy network 2, also can be used for fixing whole skull and implant plate.Net, apart from large, can see through X-ray, facilitates the inspection of intracranial disease situation.The design of double-layer alloy net, guaranteeing that morphotropism is good, easily moulding, shorten in the situation of operating time, increased the intensity of hone lamella, the appearance that has alleviated medical worker's labor intensity and post-operative complication simultaneously.
In prioritization scheme, the distance between the parallel netting twine of described every layer of alloy network 2 is 18mm.
Because polymethyl methacrylate is very high to+60 ° of room machine intensity in Celsius-183 °, can the easier plastotype of deliquescing between 70～90 ℃, character processed is moulded in cooling rear accurate maintenance.So during concrete operations, medical worker repaiies to this utility model according to the damaged shape of patient's skull that the temperature range of 70～90 ℃, to carry out secondary moulding, and because 2 layers of alloy networks have double-deck cross layered structure, the two coordinates the intensity that increases whole skull and implant plate, dual fail-safe, reliability is high.Polymethyl methacrylate layer 1 is pressed close to human body skin, is not subject to the impact of ambient temperature, and it is sharp keen effectively to have solved titanium alloy reticulated panel edges, and the problem of the complication such as scalp pain easily occurs after the thinner operation in patients of scalp.
It should be noted that; particular of the present utility model have been described in detail this utility model; for a person skilled in the art, the various apparent change of in the situation that not deviating from spirit and scope of the present utility model, it being carried out is all within protection domain of the present utility model.
