Abstract

The utility model relates to an artificial skull lamina, which belongs to an operation built-in object for treating brain trauma or skull defects after the operations for tumours in skull formation operations. The utility model is an elliptical tray-shaped lamina made of ultrahigh molecular weight polyethylene material. Small lamina holes are uniformly distributed on the artificial skull lamina, the convex surface of the artificial skull lamina is compressed into a coarse pitting surface provided with granule or cloth mark, and the concave surface of the artificial skull lamina is a smooth surface. The utility model has the advantages that the material can be economically taken; the manufacturing process is simple; the compatible performance of the artificial skull lamina with human organism is good; the hardness is moderate; the artificial skull lamina is non-perishable; the opportunity of subcutaneous dropsy and infection can be reduced after operation; the operation is simple; the success ratio of the operation can reach 100%; new trauma or pain can happen to patients.

Description

Artificial skull lamina

This utility model relates to a kind of artificial cranium plate, belongs to skull and forms a kind of operation inner matter for the treatment of cerebral trauma or tumor post-operation defect of skull in the art.

At present skull forms that the operation inner matter generally uses poly (methyl methacrylate) plate in the art, uses hydrops under the early stage concurrent scalp of this inner matter and the danger of infection is arranged, and the later stage lucite is easily aging, and slight bump is then easily broken; Use silicane rubber plate from body bone, titanium alloy sheet, synthetic terylene net, composite rib osseous tissue lobe etc. instead for what overcome that above-mentioned shortcoming has, material is different with structure, but all there is different defectives, as from the body bone, do not allow sometimes to take off and complete bury stand-by from the body skull, the easily downright bad or absorption of this bone, its survival rate only has 44%, titanium alloy sheet, and it is to the caloric response sensitivity, be difficult for mouldingly, and scalp hydrops and infection take place easily; The silicane rubber plate of synthetic terylene net, its hardness is little, easy loose shift, composite rib osseous tissue lobe wound face is big, gives patient at spirit, the human body with cause big burden economically, is difficult for promoting.

The purpose of this utility model is to overcome weak point of the prior art and provides a kind of does not increase new wound and misery to patient, durable in use, hardness is moderate, and is good with the tissue compatibility performance, cracky does not use back hypohydrops and the few a kind of artificial cranium plate of infection chance.

The purpose of this utility model is achieved in that artificial cranium plate adopts ultra-high molecular weight polyethylene, compression moulding is the shallow dished plate in ellipse garden, approximate with the profile of division header skull, be evenly distributed with little plate hole above, its convex surface is compression molded into and has granule sample or the thick pitted skin of cloth grain pattern, for the scalp tissue attached lid of growing, concave surface is even surface (need not fineness).

The purpose of this utility model can also realize by following measure: get out equidistant little plate hole on cranium plate face, distance between borehole is the 25-30 millimeter, the aperture is the 2-2.5 millimeter, the cranium plate is made large, medium and small three models, large size is 190 * 120 millimeters, medium size is 120 * 90 millimeters, and trumpet is 100 * 80 millimeters.

This utility model has following advantage compared to existing technology:

1, the economy of drawing materials is convenient to sterilization, and is good with the tissue compatibility performance;

2, this artificial cranium plate has enough flintinesses, so cracky not;

3, hydrops and infection chance are few under this artificial cranium slab of use;

4, operation method is simple, does not increase new wound and misery to patient.

The drawing of accompanying drawing is described as follows:

Accompanying drawing is a structural representation of the present utility model.

Among the figure: cranium plate convex surface (1), little plate hole (2), cranium plate concave surface (3).

Embodiment is described in further detail below in conjunction with (accompanying drawing): be compression molded into the shallow dished plate in ellipse garden with superhigh molecular weight polyethylene material, referring to accompanying drawing.Be drilled with equidistant little plate hole (2) on the cranium face, cranium plate convex surface (1) is compression molded into pitted skin, and concave surface (3) is made the even surface of no fineness, looks wound face when artificial cranium plate is made above-mentioned large, medium and small three models for operation and selects to use.

When using artificial cranium plate, the preceding size of art according to patient's defect of skull, choose the artificial cranium plate of respective model, it is standby to sterilize, in the art finishing of periphery that the cranium plate is damaged and remove a little outside plate after, again artificial cranium plate finishing is conformed to size with the shape of defect of skull, its edge just in time buckle closure bores 4-6 hole respectively in artificial cranium panel edges and bone edge on it again, fixes with stainless steel silk, behind the normal saline flushing operation wound, sew up flap and get final product.

Claims

1, a kind of artificial cranium plate, compression moulding is the shallow dished plate in ellipse garden, and is approximate with the profile of division header skull, it is characterized in that it is to be made by superhigh molecular weight polyethylene material, be evenly distributed with little plate hole above, its convex surface is compression molded into and has granule sample or the thick pitted skin of cloth grain pattern, and concave surface is an even surface.

2, artificial cranium plate according to claim 1 is characterized in that the platelet distance between borehole is the 25-30 millimeter, and the aperture is the 2-2.5 millimeter.
