Abstract
The utility model discloses a femur implant. The femur implant is composed of a femur neck 1 and a femur stem 2. The femur stem 2 is made of a porous tantalum material. The femur neck 1 is made of a compact metal material. One or more horizontal protruding edges 3 are arranged on the femur stem 2, wherein the protruding edges 3 are parallel to one another, the heads of the protruding edges 3 are aligned, the tails of the protruding edges 3 are aligned, and the protruding edges 3 are arranged at equal intervals. By the adoption of the femur implant with the structure, the femur implant is not prone to rotation and sinking, the safe reliability of the femur implant is improved, the biocompatibility of the femur implant is improved, and the femur implant can well play a role.
Description
Technical field
This utility model relates to a kind of femur implant, relates in particular to that a kind of difficult rotation sinking, security reliability are high, the femur implant of good biocompatibility.
Background technology
Implant operation is a kind for the treatment of and the operation of repairing bone injury, in the treatment at each position of health, has brought into play great role, is widely applied.Implant operation often is used for the treatment of Hip injury, will plant the implant implant into body to substitute original osseous tissue.In prior art, the femur implant surfaces generally has longitudinal fluting, its role is to reduce shearing force, increases the adhewsive action of bone cement to implant.But existing implant easily rotates sinking, the maintenance shakiness, security reliability is not high.And existing implant material therefor biocompatibility is not strong, easily causes post-operative recovery not good, affects implant and gives full play to effectiveness.
The utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide that a kind of difficult rotation sinking, security reliability are high, the femur implant of good biocompatibility.
To achieve these goals, this utility model by the following technical solutions: the femur implant is comprised of neck of femur and femoral stem; Described femoral stem consists of the porous tantalum material, and described neck of femur consists of the compact metal material; Described femoral stem is provided with the fin of one to multiple level; Described fin is parallel to each other, the head and the tail alignment, and spacing distance equates.
As the improvement to the technical program, the quantity of described fin is 3 to 6.
As the improvement to the technical program, blasting treatment has been carried out on described femoral stem surface.
Compared with the prior art, this utility model, owing to having adopted technique scheme, makes implant be difficult for rotation and sinks, and has improved the security reliability of implant, has strengthened the biocompatibility of implant, and implant is played effectiveness better.
The accompanying drawing explanation
The structural representation that Fig. 1 is this utility model embodiment.
In figure: 1 neck of femur, 2 femoral stem, 3 fins.
The specific embodiment
Below by embodiment, this utility model is specifically described; be necessary to be pointed out that at this following examples are only for being further detailed this utility model; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.
Embodiment: a kind of femur implant, as Figure 1-3, the femur implant is comprised of neck of femur 1 and femoral stem 2; Described femoral stem 2 consists of the porous tantalum material, and described neck of femur 1 consists of the compact metal material; Described femoral stem 2 is provided with the fin 3 of one to multiple level; Described fin 3 is parallel to each other, the head and the tail alignment, and spacing distance equates.
Preferably 3 to 6 of the quantity of described fin 3.The present embodiment is 4.
In order to strengthen the adhesive force of bone cement to implant, blasting treatment has been carried out on described femoral stem 2 surfaces.
On femoral stem, the design of fin can effectively prevent implant rotation sinking, with respect to common longitudinal fluting, has better retention effect, and security reliability is higher.The porous tantalum material can improve whole biocompatibility, improve implant and human body bone in conjunction with effect, be conducive to postoperative fast quick-recovery, implant is played effectiveness better.
