Abstract
The invention discloses an acetabulum cushion block which is planted into a hip joint acetabulum. The acetabulum cushion block comprises a bone trabecula (1), wherein a plurality of holes (2) are formed in the bone trabecula (1); an acetabular bone can enter the holes (2) for integrating the bone trabecula (1) with the acetabulum. The acetabulum cushion block disclosed by the invention is convenient and flexible for operation, and more practical; the bone ingrowth is good, the prosthesis implantation is stable and the fixation is relatively firm.
Description
Technical field
The present invention relates to a kind of medical prosthesis, particularly relate to a kind of acetabular bone cushion block of replacing acetabular bone necroses.
Background technology
Acetabular bone cushion block is the surgical implant replacing human hip acetabular bone part, it is mainly used in the case having serious hip defect in the replacement operation of hip joint for acetabular bone, existing acetabular bone cushion block is processed by titanium alloy material, has easy to process, processing cost advantages of higher.
Although existing acetabular bone cushion block can substitute the human body acetabular bone of Cranial defect, but but find when reality uses itself and human body acetabular bone install after clinical loosening rate higher, cause again to carry out revision procedure, bring the misery on very large health and loss economically to patient.
Existing acetabular bone cushion block mainly has following shortcoming:
1) difficulty is installed in operation, and acetabular bone cushion block is the works machined in advance by drawing standardization, cannot the concrete condition according to patient in operation process adjust flexibly;
2) surface is blasting craft, and surface is coarse not, and Bone Ingrowth is poor, in motor process long-term in human body, easily causes loosening of acetabular bone cushion block, causes the dislocation of acetabular bone.
Summary of the invention
One is the object of the present invention is to provide to be fixed on supracotyloid acetabular bone cushion block.
For achieving the above object, the concrete technical scheme of a kind of acetabular bone cushion block of the present invention is:
A kind of acetabular bone cushion block, for implanting in hip joint acetabular bone, is characterized in that, comprising bone trabecula, bone trabecula is provided with multiple hole, acetabular bone can enter in hole to make bone trabecula and acetabular bone merge.
Further, bone trabecula is provided with nail, nail is the through hole running through bone trabecula both ends of the surface, and screw can be connected with acetabular bone through nail, is fixed on acetabular bone to make bone trabecula.
Further, the multiple holes on bone trabecula are cellular on bone trabecular outer surface.
Further, bone trabecular outside wall surface is matsurface.
The advantage of a kind of acetabular bone cushion block of the present invention is:
1) facilitating operation, flexibly, more practical;
2) Bone Ingrowth is good, and Using prosthesis is stablized, and fixing comparatively firm, the surface of prosthese has loose structure, for Bone Ingrowth provides space, promotes the ankylose of cambium and prosthese;
3) external form of acetabular bone cushion block and the bone trabecula of human body similar, can be raw in biological support, enhance the bond strength of acetabular bone cushion block and skeleton;
4) can punch on acetabular bone cushion block prosthese by the concrete condition of patient in clinical operation temporarily, make acetabular bone cushion block fixing more reasonable.
Accompanying drawing explanation
Fig. 1 is the structural representation of acetabular bone cushion block of the present invention;
Fig. 2 is the partial side view of acetabular bone cushion block of the present invention.
Detailed description of the invention
In order to better understand object of the present invention, structure and function, below in conjunction with accompanying drawing, further detailed description is done to a kind of acetabular bone cushion block of the present invention.
As depicted in figs. 1 and 2, it shows for a kind of acetabular bone cushion block of the present invention, for replacing the necroses of hip joint acetabular bone, comprise bone trabecula 1, bone trabecula 1 is provided with multiple hole 2, hole 2 forms according to the arrangement of certain regular array, and acetabular bone can enter in hole 2 to make bone trabecula 1 and acetabular bone merge, the cell tissue facilitating acetabular bone combines with acetabular bone cushion block, and acetabular bone cushion block Absorbable organic halogens is implanted in acetabular bone.It should be noted, the scope arranging hole 2 covers on whole bone trabecula 1, and multiple hole 2 in cellular, can incorporate completely in acetabular bone pad to make the acetabular bone after in implantation acetabular bone on the outer surface of bone trabecula 1.
Further, the outside wall surface of bone trabecula 1 is matsurface, and acetabular bone pad can be fixed in acetabular bone, not easily loosens, and avoids acetabular bone dislocation.
Further, bone trabecula 1 is provided with nail 3, nail 3 is for running through the through hole of bone trabecula 1 both ends of the surface, and screw can be connected with acetabular bone through nail 3, is fixed on acetabular bone to make bone trabecula 1.Wherein, bone trabecula 1 being provided with multiple nail 3, can the concrete condition according to patient in clinical operation punch in the position of nail, and to make bone trabecula and acetabular bone rationally be fixed together, operation is installed more convenient.
A kind of acetabular bone cushion block of the present invention, facilitating operation, flexibly, more practical; Bone Ingrowth is good, and Using prosthesis is stablized, and fixing comparatively firm, the surface of prosthese has loose structure, for Bone Ingrowth provides space, promotes the ankylose of cambium and prosthese; The external form of acetabular bone cushion block is similar to the bone trabecula of human body, can give birth to, enhance the bond strength of acetabular bone cushion block and skeleton in biological support; Can punch on acetabular bone cushion block prosthese by the concrete condition of patient in clinical operation temporarily, make acetabular bone cushion block fixing more reasonable.
Further describe invention has been by specific embodiment above; but it should be understood that; here concrete description; should not be construed as the restriction to the spirit and scope of the invention; one of ordinary skilled in the art to the various amendments that above-described embodiment is made, belongs to the scope that the present invention protects after reading this specification.
