Abstract
The utility model relates to a fiber multihole titanium rod for repairing caput femoris with ischemic necrosis. The fiber multihole titanium rod comprises a fiber multihole titanium rod body and a nano fermorite layer coated on the outer surface of the fiber multihole titanium rod body, wherein the diameter of the fiber multihole titanium rod body is 1 to 2 cm; the fiber multihole titanium rod body is 50 to 80 cm high; the aperture is 100 to 800 mu m; the porosity is 80.0+/-2.0 percent; and holes can be communicated with one another. The fiber multihole titanium rod is embedded into the caput femoris with ischemic necrosis, can replace the part with ischemic necrosis to achieve a powerful supporting effect, and promote adhesion, increment and differentiation of cells on the basis of keeping the characteristic of the conventional fiber multihole material, so that bones are effectively induced to be formed, and bone integration and bone bonding are improved.
Description
Technical field
This utility model relates to the material in a kind of biomedical engineering technology field, relates in particular to a kind of fiber multihole titanium rod that ischemic necrosis of femoral head is repaired that is used for.
Background technology
Ischemic necrosis of femoral head (ANFH) is the osteocyte gangrenosum acne pathological changes that causes owing to femoral head blood supply disorder that a variety of causes causes, is one of orthopedics department pathological changes of being difficult to cure, and the patient takes action limited, and health is very painful.The cause of disease of ischemic necrosis of femoral head mainly is because the ischemic femoral head face causes femur head necrosis, the collapse of the femoral head that the stressed heavy burden of femoral head causes.
At present, clinical general employing operative treatment.As core decompression add that bone grafting, blood vessel are implanted, band boat lobe or vascular pedicle bone lobe implant and various bone-culting operation, with the capital blood fortune of try reconstruct, capitally further subsides but all can't stop, its reason is mainly due to lacking strong support in the femoral head.
Summary of the invention
The purpose of this utility model provides a kind of fiber multihole titanium rod that ischemic necrosis of femoral head is repaired that is used for exactly in order to address the above problem, it is implanted in the femoral head of ischemic necrosis, plays strong supporting role.
The purpose of this utility model is achieved in that
A kind of fiber multihole titanium rod that is used for the ischemic necrosis of femoral head reparation of this utility model; Comprise fiber multihole titanium rod body and the nanometer saamite layer that is wrapped in said this external surface of fiber multihole titanium rod; The excellent diameter of said fiber multihole titanium rod body is 1～2cm, and excellent height is 50～80cm, and pore-size distribution is 100～800 μ m; Porosity is 80.0 ± 2.0%, is interconnected between the hole.
The above-mentioned fiber multihole titanium rod that is used for the ischemic necrosis of femoral head reparation, wherein, said fiber multihole titanium rod body is processed by pure titanium fiber.
The above-mentioned fiber multihole titanium rod that is used for the ischemic necrosis of femoral head reparation, wherein, the comprcssive strength of said fiber multihole titanium rod body is 15.0～16.0Mpa, elastic modelling quantity is 0.90～1.20GPa.
Above-mentioned be used for the fiber multihole titanium rod that ischemic necrosis of femoral head is repaired, wherein, the component and the mass percent thereof of described nanometer saamite layer are respectively: 66.46% nanometer saamite, 0.299% sodium chloride and 33.24% distilled water.
This utility model fiber multihole titanium rod; It is implanted in the femoral head of ischemic necrosis, not only can substitute defect area, play strong supporting role; Can also be on the basis that keeps original fiber multihole material behavior; Promote osteoblasticly to stick, breed and break up, more effectively induce the formation of bone, enhance bone is integrated and the bone bonding.
Description of drawings
Fig. 1 is the structural representation (broken section) of this utility model.
The specific embodiment
See also Fig. 1, this utility model fiber multihole titanium rod 1 is used for the ischemic necrosis of femoral head reparation; Comprise fiber multihole titanium rod body 2 and the nanometer saamite layer 3 that is wrapped in said fiber multihole titanium rod body 2 outer surfaces; The excellent diameter of fiber multihole titanium rod body 2 is 1～2cm, and excellent height is 50～80cm, and pore-size distribution is 100～800 μ m; Porosity is 80.0 ± 2.0%, is interconnected between the hole.This fiber multihole titanium rod body 2 is processed by pure titanium fiber, and its comprcssive strength is 15.0～16.0Mpa, and elastic modelling quantity is 0.90～1.20GPa.The component and the mass percent thereof of described nanometer saamite layer 3 are respectively: 66.46% nanometer saamite (Sr
10(PO

6(OH)
2), 0.299% sodium chloride and 33.24% distilled water.
This utility model fiber multihole titanium rod is implanted in the femoral head of ischemic necrosis, can be substituted defect area, play strong supporting role.Fiber multihole titanium rod and the compound repairing bone defect of nanometer saamite can be on the bases that keeps original fiber multihole material behavior, promote osteoblasticly to stick, breed and break up, and more effectively induce the formation of bone, enhance bone integration and bone bonding.
Above embodiment only supplies to explain the usefulness of this utility model; But not to the restriction of this utility model; The technical staff in relevant technologies field under the situation of spirit that does not break away from this utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of this utility model, should be limited each claim.
