Embodiment Construction

[0012] Such as figure 1 , figure 2 , Figure 4 As shown, the present invention is composed of hydroxyapatite powder, silk net, hollow nylon net, coral hydroxyapatite particles added with antibiotics, and biological titanium screws. Hydroxyapatite powder 1 is located on the first layer, and silk net 2 is located on the The second, third, and fourth layers are hollow nylon mesh 3, the fifth and sixth layers are silk mesh 2, and the seventh layer is coral hydroxyapatite particles 4 with antibiotics added. Connected by adhesive; the hydroxyapatite skull implant is semicircular arc-shaped, with a diameter of 7-30cm, an arc height of 1-10cm, and a thickness of 1-2mm; there are fixing holes on the outer ring of the arc surface 5 , hole diameter: 1-2.5mm, hole center distance: 1.5mm, the inner ring is the drainage growth hole 6, hole diameter: 2.5-3.5mm, hole center distance: 1.5mm; biological titanium screws pass through the fixing hole 5 and The cranial phase is fixed. Such as ...

Abstract

The cranial bone implant consists of hydroxyapatite powder in the first layer, silk net in the second, third, fifth and sixth layers, hollow nylon net in the fourth layer, antibiotic adding coral hydroxyapatite particle in the seventh layer and biological titanium screws. There is adhesive between the layers. The implant is semicircular and has fixing holes in the outer circle and drainage and growth holes in the inner circle. It has high shock resistance, and can be formed easily and fused with autogenous bone.

Description

technical field [0001] The invention relates to a skull implant for medical equipment, in particular to a hydroxyapatite skull implant. Background technique [0002] There are currently several types of artificial skulls in the repair of skull defects at home and abroad: 1. Titanium skull repair materials are only in sheet form. Its advantage is strong impact resistance. The disadvantages are that it is difficult to shape, the temperature conductivity is strong, the patient is prone to intracranial discomfort, and it cannot be fused with the autogenous bone. 2. Hydroxyapatite biomaterials have been used in the United States. They need to be ordered in advance, and cannot be molded on site. They are expensive and easy to break. 3. For medical polymer composite materials, the glass fibers (fine fibers) in the materials are carcinogenic. Contents of the invention [0003] The purpose of the present invention is to provide a new type of skull defect repair material - hydrox...
