Abstract
The invention discloses an artificial hip joint on a bone trabecula microporous surface, which is designed for solving the problem of secondary operation repairing caused by later-period loose or sunk acetabulum or femoral stem existing in a traditional artificial hip joint. The artificial hip joint on a bone trabecula microporous surface comprises a femoral stem body, wherein a stem neck is arranged at the upper end of the femoral stem body and is in socket joint with an acetabulum liner, a femoral ball head is in socket joint outside the acetabulum liner, an acetabulum cup is in socket joint outside the femoral ball head, and a bone trabecula microporous layer is formed on at least one of the outer surfaces of the femoral stem body and the acetabulum cup. After the artificial hip joint is implanted into a human body, the artificial hip joint and natural bones can be integrally fixed to effectively enhance the fixation effect, prevent the artificial hip joint from loosening or sinking for a long time and prolong the service life.
Description
Technical field
The present invention relates to a kind of artificial hip joint, relate in particular to the artificial hip joint that a kind of surface of using has bone trabecula microporous layer in the surgery joint replacement surgery, belong to technical field of medical instruments.
Background technology
At present, the artificial hip joint replacing operation, become the medical circle treatment hip joint a kind of unique effective method that the class disease generally adopts of disabling, in this operation, acetabular bone that implant in the postoperative joint and the fixed effect between femoral stem and the natural bone are the decision artificial joint keys in service life.Fixing means commonly used now has two kinds, and a kind of is the bone cement technique for fixing that is applicable to elderly patient, and another kind is the biological fixation technology that is applicable to young patient.Wherein, general biological fixation technology forms the micropore surface layer by methods such as pellet sintering or the braidings of titanium silk on acetabular bone and femoral stem, for growing into of osteocyte creates conditions, yet the porosity of this microporous layers is low, 10-20% is only arranged, and the osteocyte amount of growing into is few and trickle.In addition, also a large amount of in recent years modes that adopt at acetabular bone and femoral stem surface spraying titanium valve or spraying hydroxyapatite induce osteocyte to grow into by titanium valve or hydroxyapatite, and be attached to realize on the rough surface of prosthese fixing.Above-mentioned various biological fixation method, through clinical confirmation for many years, frequent appearance makes troubles and misery to the patient because of loosening, the sinking of late period acetabular bone or femoral stem cause second operation to be overhauled.
Bone trabecula is the extension of cortical bone in spongy bone, be that bone trabecula is connected with cortical bone, in cortical bone, form irregular space network, as Retinervus Luffae Fructus sample or spongy, between network, form the micropore of countless mutual perforations, these micropores play supporting role, for soft tissue and vascularization provide the growing space.
Summary of the invention
The purpose of this invention is to provide a kind of artificial hip joint on bone trabecula microporous surface, this artificial hip joint can be realized the integrated fixing of prosthese and natural bone, prevents the loosening and sinking of prosthese.
For achieving the above object, the present invention adopts following technical scheme:
Artificial hip joint on bone trabecula microporous surface provided by the invention, comprise a femoral stem body, the upper end of this femoral stem body is provided with the handle neck, be socketed with the femur bulb on this handle neck, this femur bulb overcoat is connected to the mortar lining, the outer acetabular cup that is socketed with of this mortar lining, at least one in described femoral stem body and the acetabular cup outer surface is formed with bone trabecula microporous layer.
Wherein, the outer surface of described bone trabecula microporous layer is provided with hydroxyapatite coating layer or titanium valve layer.
Further, the outer surface and the surface of internal cavity of described bone trabecula microporous layer are provided with hydroxyapatite coating layer or titanium valve layer.
The thickness of described bone trabecula microporous layer is 0.5--10mm.
Described bone trabecula microporous layer is the Retinervus Luffae Fructus shape, is connected and composed by metal bar rule and/or irregular being interweaved.
The rugosity of described metal bar or diameter are 0.1--3mm.
The material of described metal bar is titanium alloy or cobalt alloy.
The top of described femoral stem body is the nearly triangle bodily form, the bottom is cone-shaped, and described femoral stem body top is tapered from top to bottom excessively, and inboard tapered excessive by the lateral, femoral stem body upper inner is interior circular arc; The external side of femoral stem is shape linearly.
The bone trabecula microporous layer of described femoral stem external surface is arranged on the outer surface on handle body top or is arranged on the outer surface of whole handle body.
Artificial hip joint on bone trabecula microporous surface provided by the invention, be bone trabecula microporous layer to be set at femoral stem body that has the artificial hip prosthesis now and acetabular cup outer surface, this bone trabecula microporous layer is the Retinervus Luffae Fructus shape, connect and compose by metal bar rule or irregular being interweaved, formation is similar to bone trabecular architectural feature, porosity reaches 50-80%, and intensity is between cortical bone and the spongy bone; Behind artificial hip joint implant into body of the present invention, the osteocyte president that human body natural's bone bears goes in the microporous layers, in microporous layers, be interweaved,, and follow soft tissue to grow into and the vascularization generation around locking, form new bone trabecula, natural bone and prosthese are grown together, thereby realize the integrated fixing of prosthese and natural bone, strengthen fixed effect effectively, can prevent the loosening and sinking of articular prosthesis for a long time, increase the service life.
