Abstract
The utility model relates to a simple artificial hip joint femoral component prosthesis. The prosthesis comprises a hip joint femoral component which is formed by connecting a cervical vertebrae opening (1), a handle neck (2) and a handle body (3). The prosthesis is characterized in that the cervical vertebrae opening (1), the handle neck (2) and the handle body (3) are integrally formed through adopting medical titanium alloys; grooves of 5-10 millimeters are also respectively formed on the front and back surfaces of the handle body (3), and porous tantalum workpieces (5) are respectively attached to the grooves, so that the grooves after being attached are parallel and level to the surface of the handle body (3); and an elongated slot punch hole (4) is formed in a near end face of the handle body (3). The hip joint femoral component is simple in structure, and bones can grow into the porous tantalum workpieces which are attached onto the surfaces of the handle, so that the porous tantalum workpieces and human bone tissues can organically combined into a whole, so that real biological fixation is realized.
Description
Technical field
This utility model relates to the medical domain artificial joint, relates in particular to a kind of simple and easy artificial hip joint femoral shaft prosthese.
Background technology
Known medical science hip replacement surgery is the hip joint of manufacturing by implantable artificial in vivo, to rebuild the anatomical structure of human hip, and makes it obtain normal mechanical property to complete certain physiological function.
Artificial hip joint is to consist of the first-class parts of femoral stem, acetabular cup and femur, wherein femoral stem is as the link that connects human femur under loading and human body far-end, play fixing and supporting role in human body, its structural design and material property are directly connected to the therapeutic effect of hip replacement surgery.But the artificial hip joint femoral shaft of existing existing design exists in application: after long-time the use and tissue there will be repulsion, biocompatibility is poor and affect its service life; Fitting operation is extremely inconvenient, adjusts the direction that leans forward and need to adopt special-purpose instrument, has increased the time of replacement, has increased the weight of patient's physiological load.These problems are directly connected to the therapeutic effect of hip replacement surgery, thereby urgently to be resolved hurrily.
The utility model content
The purpose of this utility model is to provide a kind of simple and easy artificial hip joint femoral shaft prosthese, and this femoral hip stem has good biocompatibility, and install and adjust is very convenient rapidly.
The purpose of this utility model is achieved in that
A kind of simple and easy artificial hip joint femoral shaft prosthese, it is to include the femoral hip stem that cervical vertebra mouth, handle neck and handle body disjunctor form, and it is characterized in that: described cervical vertebra mouth, described handle neck and described handle body adopt medical titanium alloy one-body molded; Also be provided with the groove of 5～10 millimeters on the handle surface of the front and back side of described handle body, be attached with the porous tantalum product in this groove, so that this groove flushes with the handle surface after adhering to; Be provided with long trough on the proximal end face of described handle body and squeeze into hole.
The porous tantalum product adhered in groove on the handle surface of the front and back side of above-mentioned handle body, its porosity is 60～70%.This porous tantalum product, can adopt the preparations such as foam dipping method, die pressing.Through the discovery that studies for a long period of time: adopt the femoral hip stem of this porous tantalum product when greatly having improved its biocompatibility, also well met its mechanical property, greatly improve service life and implanted comfort level, and the porous tantalum product structure that can make bone grow into, hole on rough external surface is inwardly grown, the structure of growing in formation, with body bone tissue, organically combine as a whole, after can making femoral stem implant pulp cavity and between spongy bone, mutually embed, can increase on the one hand the stability after prosthese is implanted, can increase on the other hand the anti-verticity of prosthese, the final prosthese stability at a specified future date that increases.
The surface of above-mentioned handle body also evenly is provided with the hydroxyapatite surface coating, so that it has the function of inducing bone cell growth.
The long trough arranged on the proximal end face of above-mentioned handle body is squeezed into hole, its long 1～15 millimeter, wide 1～10 millimeter, dark 1～15 millimeter.If this size is excessive, can affect the intensity of handle body; If too small, can affect the intensity of erecting tools.
The utlity model has following beneficial effect:
This femoral hip stem is simple in structure, and the porous tantalum product that its handle surface is adhered to can make bone grow into, and has realized organically combining as a wholely with body bone tissue, reaches real biological fixation.In addition, the long trough on the handle body is squeezed into hole, has facilitated erecting tools hip joint stalk to be squeezed into and adjusted the cone mouth direction, has reduced the time of replacement, has reached easy for installation, purpose accurately.
The accompanying drawing explanation
Fig. 1 is the structural representation of the simple and easy artificial hip joint femoral shaft prosthese in this utility model embodiment 1.
Fig. 2 is that the K that squeezes into pore structure that arranges on handle body proximal end face in Fig. 1 is to view.
The specific embodiment
Be below this utility model preferred embodiment, and be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Fig. 1～2: a kind of simple and easy artificial hip joint femoral shaft prosthese, it is to include the femoral hip stem that cervical vertebra mouth 1, handle neck 2 and handle body 3 disjunctors form, the size of its overall dimensions and existing artificial hip joint stem is basic identical; Its cervical vertebra mouth 1, handle neck 2 and handle body 3 adopt medical titanium alloy one-body molded; Also be provided with the groove of 6 millimeters deep on handle body 3 surfaces of the front and back side of handle body 3, dash area in the porous tantalum product 5(figure that to be attached with porosity in this groove be 60～70%) so that this groove after adhering to handle body 3 flush; Be provided with long trough on the proximal end face of handle body 3 and squeeze into hole 4, this squeeze into hole 4 length be 8 millimeters, wide be 4 millimeters, be 3 millimeters deeply; The surface of this handle body 3 also evenly is provided with the hydroxyapatite surface coating, so that it has the function of inducing bone cell growth.
When femoral stem in the present embodiment is installed, what can directly by driver, be applied to it squeezes into hole 4 install and adjust cone mouth directions, simple to operate, reliable, rapid.
