Description

The hip joint combined handle of use is transplanted in a kind of bone displacement
Technical field
This utility model relates to the displacement of medical domain bone and transplants the artificial joint of use, relates in particular to a kind of bone displacement and transplants the hip joint combined handle of use.
Background technology
When the hip joint that clinical medicine various hip joint disease late periods for the treatment of such as a variety of causes such as femur head necrosis, osteoarthritis cause destroys, generally adopt the method for hip replacement surgery, the hip joint made of implantable artificial in vivo, to rebuild the anatomical structure of human hip, and make it obtain normal mechanical property to complete certain physiological function, reach thus alleviating pain, improve the purpose of function.
Artificial hip joint is to consist of femoral stem and the first-class parts of femur, and wherein femoral stem, as the link that connects human femur under loading and human body far-end, plays fixing and supporting role in human body.But when the artificial hip joint femoral shaft of existing existing design is installed, after this handle is implanted, as the cone mouth direction of handle, namely lean forward direction need to adjust the time, operate extremely inconvenient, and need the another special-purpose instrument that adopts, increased the time of replacement, increased the weight of patient's physiological load.In addition, it is selected with structure the certain defect of upper existence is set, and causes it to there will be repulsion with tissue after long-time the use, and biocompatibility is poor and affect its service life.These problems are directly connected to the therapeutic effect of hip replacement surgery, thereby need to be resolved hurrily.
The utility model content
The purpose of this utility model is to provide a kind of bone displacement to transplant the hip joint combined handle of use, and this femoral hip stem can facilitate promptly realizes install and adjust, and has good biocompatibility concurrently.
The purpose of this utility model is achieved in that
The hip joint combined handle of use is transplanted in a kind of bone displacement, it is to include the femoral hip stem that cervical vertebra mouth, handle neck, handle body and handle WEILIAN body form, it is characterized in that: described cervical vertebra mouth, described handle neck and described handle body all are set to the porous tantalum product, adopt one-body molded; The lower end of described handle body is provided with locating hole; An end that is connected with the handle body on described handle tail is provided with positioning boss, to coordinate the locating hole on the installing handle body, and realizes connection both; Be provided with long trough on the proximal end face of described handle body and squeeze into hole.
Above-mentioned cervical vertebra mouth, above-mentioned handle neck and above-mentioned handle body all are set to the porous tantalum product, and its porosity is 60~70%.These porous tantalum products, 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 bone is grown into, hole on rough external surface is inwardly grown, the structure of growing in formation, organically combine as a whole with body bone tissue, mutually embed after can making femoral stem implant pulp cavity and between spongy bone, 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.
An end that is connected with the handle body on above-mentioned handle tail also is provided with Rotary-table, can prevent that this femoral hip stem from sinking.
The long trough that arranges 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.
Adopt interference type to insert between locating hole on positioning boss on above-mentioned handle tail and above-mentioned handle body and is connected, more and more tighter under the effect of human bady gravitational, connect reliably.
The utlity model has following beneficial effect:
This femoral hip stem, owing at the handle tail, being provided with Rotary-table, can prevent that this femoral hip stem from sinking; Squeeze into hole owing to being provided with long trough on the proximal end face at the handle body again, erecting tools can directly be squeezed into hip joint stalk and adjust the cone mouth direction by this hole, reduced the time of replacement, has reached easy for installation, purpose accurately.In addition, this femoral hip stem has not only improved the biocompatibility of this artificial joint greatly, and mechanics and the similar people's bone of biological property, well met its mechanical property simultaneously, has greatly improved the service life of this artificial joint and has implanted comfort level.
