Abstract
The utility model discloses a femoral handle implant, which comprises a handle body 1, a neck collar 2 and a ball joint 3, wherein the handle body 1 and the neck collar 2 are movably connected, the ball joint 3 is arranged on a connecting position of the handle body 1 and the neck collar 2, a screw 4 is arranged on the neck collar 2, and a plurality of porous tantalum inverted teeth 5 are arranged on the side surface of the handle body 1. The femoral handle implant is more steady and durable, improves biocompatibility, and simplifies therapeutic process.
Description
Technical field
This utility model relates to a kind of femoral stem implantation body, relate in particular to a kind of stablize durable, biocompatibility is high, the femoral stem implantation body of simplifying treatment.
Background technology
The not strong shortcoming of existing femoral stem implantation body's existence and stability, be difficult to fixing or maintenance is unstable, between femoral stem and sclerotin, easily occur loosening, and femur bears gravity and is difficult to equilibrium, easily cause femoral stem to damage, shortened the service life of femoral stem, increased turnover rate and the treatment cost of femoral stem, made therapeutic process very complicated.
The utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide a kind of femoral stem implantation body durable, that biocompatibility is high, simplification is treated that stablizes.
To achieve these goals, this utility model by the following technical solutions: femoral stem implantation body comprises handle body, neck neck and ball-joint; Described handle body and described neck neck are for being flexibly connected, and described handle body and described neck neck junction are provided with ball-joint; Described neck neck is provided with screw; Described handle body side surface is provided with a plurality of porous tantalum pawls.
As the improvement to the technical program, described porous tantalum pawl vertically equidistantly distributes.
Compared with the prior art, this utility model, owing to having adopted technique scheme, stablizes femoral stem implantation body durable more, has improved the biocompatibility of femoral stem implantation body, has simplified therapeutic process.
The accompanying drawing explanation
The structural representation that Fig. 1 is this utility model embodiment.
In figure: 1 handle body, 2 neck necks, 3 ball-joints, 4 screws, 5 porous tantalum pawls.
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 femoral stem implantation body, as shown in Figure 1, femoral stem implantation body comprises handle body 1, neck neck 2 and ball-joint 3; Described handle body 1 and described neck neck 2 are for being flexibly connected, and described handle body 1 and described neck lead 2 junctions to be provided with ball-joint 3; Described neck neck 2 is provided with screw 4; Described handle body 1 side surface is provided with a plurality of porous tantalum pawls 5.
Preferably, described porous tantalum pawl 5 vertically equidistantly distributes.
During use, handle body and neck neck junction are provided with ball-joint, and handle body and neck neck are flexibly connected by ball-joint.Screw contributes to improve the connective stability of structure.The porous tantalum pawl can effectively improve the biocompatibility of structure, strengthens the stability of structure, prevents that the handle body from sinking.The femoral stem implantation body of this structure, simple and compact for structure, connect reliably, maintenance is stable, not only can make femoral stem relative with femur fixing, and the gravity balance that femur is born distributes, can effectively prevent between femoral stem and sclerotin occurring to become flexible, make structure not fragile, improve the ruggedness of femoral stem, save treatment cost, simplify therapeutic process.
Claims (2)
1. a femoral stem implantation body is characterized in that: described femoral stem implantation body comprises handle body (1), neck neck (2) and ball-joint (3); Described handle body (1) and described neck neck (2) are for being flexibly connected, and described handle body (1) and described neck neck (2) junction are provided with ball-joint (3); Described neck neck (2) is provided with screw (4); Described handle body (1) side surface is provided with a plurality of porous tantalum pawls (5).
