Abstract

The utility model relates to a simple artificial hip joint femoral component for bone replacement transplantation. The simple artificial hip joint femoral component for bone replacement transplantation comprises a head portion (2) and a component body (1) and is characterized in that a plurality of longitudinal grooves (11) are evenly distributed in the circumference of the lower end of the component body (1); the head portion (2) and the component body (1) are made of titanium alloy and integrally formed; annular grooves with the depth ranging 5mm to 10mm are further formed in the surface of the upper end of the component body (1) and each annular multi-hole tantalum part (12) is attached to one annular groove, so that each annular groove is flush with the surface of the component body (1) after one annular multi-hole tantalum part (12) is attached. The simple artificial hip joint femoral component for bone replacement transplantation is simple and stable in structure and good in biocompatibility.

Description

The simple and easy artificial hip joint femoral shaft of use is transplanted in a kind of bone displacement
Technical field
This utility model relates to the displacement of medical domain bone to be transplanted, and relates in particular to a kind of bone displacement and transplants the simple and easy artificial hip joint femoral shaft of use.
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, reach thus alleviating pain, improve the purpose of 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, in human body, play fixing and supporting role, its structural design and material property are directly connected to the therapeutic effect of hip replacement surgery.
Due to the increase of the anatomical difference of human femur under loading pulp cavity and various deformity of hip joint and even the operation of more and more hip revision, the demand degree that prosthetic designs is adapted to various deformities is more and more higher.And traditional metal hip joint handle exists; The design of borrowed structure complexity and shape is not in place, and this has directly affected the fixed effect of hip joint; Select and the structure of hip joint combined handle arranges the certain defect of upper existence, causes it after long-time the use, with tissue, to there will be repulsion, and biocompatibility is poor and affect its service life etc.How to address the above problem is the problem that this area is urgently studied at present.
The utility model content
The purpose of this utility model is to provide a kind of bone displacement to transplant the simple and easy artificial hip joint femoral shaft of use, and this hip joint stalk is simple in structure, stable, has good biocompatibility concurrently.
The purpose of this utility model is to realize like this;
The simple and easy artificial hip joint femoral shaft of use is transplanted in a kind of bone displacement, and it comprises head and handle body, it is characterized in that: on the circumference of described handle body lower end, be uniformly distributed a plurality of longitudinal grooves, to strengthen its antitorque and anti-rotational stability; Described head and described handle body adopt titanium alloy one-body molded; On De Bing surface, described handle body upper end, also be provided with the degree of depth and be the annular recess of 5~10 millimeters, in this annular recess, be attached with ring-type porous tantalum product, so that this annular recess place flushes with the handle surface after adhering to.
Above-mentioned ring-type porous tantalum product, its porosity is 60~70%.Find that through studying for a long period of time the porous tantalum product, in the biocompatibility that has greatly improved femoral hip stem, has also well met its mechanical property, greatly improved its service life and implanted comfort level.Above-mentioned porous tantalum product, can adopt the preparations such as foam dipping method, die pressing.
For further optimizing the structural design of this femoral stem, above-mentioned head is cylindrical shape; Above-mentioned handle body lower end is oval column, and far-end is taper.
The utlity model has following beneficial effect:
In this utility model this femoral hip stem is through adopting titanium alloy one-body molded, its structure more simple and stable, be easy to processing, be convenient to suitability for industrialized production.Its handle body lower end is uniformly distributed a plurality of longitudinal grooves, has strengthened its antitorque and anti-rotational stability; Handle body upper end has the porous product structure that bone is grown into, hole on rough external surface is inwardly grown, the structure of growing in formation, with body bone tissue, organically combine as a whole, reach real biological fixation, strengthened the stability that femoral stem is implanted, greatly improved the service life of this artificial joint and implanted comfort level.
The accompanying drawing explanation
Fig. 1 is the structural representation that the simple and easy artificial hip joint femoral shaft of use is transplanted in the bone displacement in this utility model embodiment 1.
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 Figure 1: the simple and easy artificial hip joint femoral shaft of use is transplanted in a kind of bone displacement, and it comprises head 2 and handle body 1; Its head 2 is cylindrical shape, and handle body 1 lower end is oval column, and far-end is taper, and is uniformly distributed a plurality of longitudinal grooves 11 on the circumference of handle body 1 lower end, to strengthen its antitorque and anti-rotational stability; Head 2 and handle body 1 adopt titanium alloy one-body molded; On handle body 1 surface of handle body 1 upper end, also be provided with the degree of depth and be the annular recess of 5 millimeters, in this annular recess, be attached with ring-type porous tantalum product 12 so that this annular recess place after adhering to handle body 1 flush; This ring-type porous tantalum product 12, its porosity is 60~70%.
The two ends, handle body up and down of this artificial hip joint femoral shaft are respectively arranged with longitudinal groove 11 and ring-type porous tantalum product 12, not only strengthened its antitorque and anti-rotational stability, also has the loose structure that bone is grown into, hole on rough external surface is inwardly grown, the structure of growing in formation, as a whole with the body bone tissue combination, reach real biological fixation, strengthened the stability that femoral stem is implanted.
