Abstract
The utility model discloses a femoral implanted prosthesis. The femoral implanted prosthesis consists of a femoral neck 1 and a femoral stem 2. The femoral stem 2 is made of porous tantalum materials, and the femoral neck 1 is made of compact metal materials. The femoral stem 2 is provided with more than one or more horizontal grooves 3. The grooves 3 are parallel to each other, and aligned with each other in a head-to-tail manner. Moreover, spacing distances are equal. The femoral neck 1 is in threaded connection with the femoral stem 2. The femoral implanted prosthesis in such structure improves the steadiness and durability, enhances the biocompatibility, and shortens the treatment course.
Description
Technical field
This utility model relates to a kind of femur implanting prosthetic, relates in particular to the femur implanting prosthetic of a kind of firm lasting, good biocompatibility, short treating period.
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 is often used for the treatment of Hip injury, will plant implanting prosthetic implant into body to substitute original osseous tissue.Easily there is the firm not lasting phenomenon of maintenance in existing implanting prosthetic.And existing implanting prosthetic material therefor biocompatibility is not strong, easily causes post-operative recovery not good, the course for the treatment of is longer.
Utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide the femur implanting prosthetic of a kind of firm lasting, good biocompatibility, short treating period.
To achieve these goals, this utility model by the following technical solutions: femur implanting prosthetic is comprised of neck of femur and femoral stem; Described femoral stem consists of porous tantalum material, and described neck of femur consists of compact metal material; Described femoral stem is provided with the groove of one to multiple level; Described groove is parallel to each other, head and the tail alignment, and spacing distance equates; Described neck of femur with femoral stem for being threaded.
As the improvement to the technical program, blasting treatment has been carried out on described femoral stem surface.
As the improvement to the technical program, the quantity of described groove is 4.
Compared with the prior art, this utility model, owing to having adopted technique scheme, has improved the firm persistency of implanting prosthetic, has strengthened the biocompatibility of implanting prosthetic, has shortened the course for the treatment of.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Fig. 2 is that each parts of this utility model embodiment split schematic diagram.
In figure: 1 neck of femur, 2 femoral stem, 3 grooves.
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 implanting prosthetic, as shown in Figure 1-2, femur implanting prosthetic is comprised of neck of femur 1 and femoral stem 2; Described femoral stem 2 consists of porous tantalum material, and described neck of femur 1 consists of compact metal material; Described femoral stem 2 is provided with the groove 3 of one to multiple level; Described groove 3 is parallel to each other, head and the tail alignment, and spacing distance equates; Described neck of femur 1 with femoral stem 2 for being threaded.
In order to strengthen the adhesive force of bone cement to implanting prosthetic, blasting treatment has been carried out on described femoral stem 2 surfaces.
Preferably 4 of the quantity of described groove 3.
The design of femoral stem upper groove can effectively prevent implanting prosthetic rotation sinking, has good retention effect, and firm persistency is high.Porous tantalum material can improve whole biocompatibility, is conducive to postoperative fast quick-recovery, Shorten the Treatment Process.
