Abstract
The invention discloses a protruded bone integrated setting nail comprising a nail body and a nail tail. A metallic tantalum layer is at least arranged on the outer surface of the nail body; a longitudinal groove is semi-cylindrical; a tantalum column is arranged in the semi-cylindrical longitudinal groove and is tangential to the excircle of a spiral tooth; and the metallic tantalum layer is positioned on the outer side of the tantalum column. The invention has the advantages of favorable biological activity, capability of ensuring the bone grows and promoting the bone to be integrated, short heeling time and high heeling intensity.
Description
Technical field
The present invention relates to a kind of synthetism nail of processus styloideus radii conformability.
Background technology
The synthetism nail be used to realize the fixing of skeleton or connect, but the biological activity of synthetism nail is poor in the human body operation, lack bone inductive effect, do not have strong chemical bond with surrounding tissue, healing time is long, can not satisfy the requirement that clinical healing is fast, synosteosis intensity is high, still need improve.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, a kind of synthetism nail is provided, biological activity of the present invention is good, can make bone grow into, promote bone to integrate, and healing time is short, healing intensity height.
Its technical scheme is as follows:
A kind of synthetism nail of processus styloideus radii conformability comprises nail body and nail tail, and the outer surface at the nail body is provided with tantalum metal layer at least.
Because tantalum metal layer has excellent biological compatibility and chemical stability, tantalum metal layer is located at the surface that synthetism is followed closely, can induce the growth of bone, shorten the symphysis time, improve symphysis intensity.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
On described nail body, be provided with thread.Marginal portion at described nail body is provided with cannelure, and described tantalum metal layer is located in this cannelure.On the nail body, offer cannelure earlier, at the cannelure place tantalum metal layer is set again, reduced difficulty of processing, reduced manufacturing cost.
Described cannelure is at least two, and is circumferentially uniform along described ailhead.As adopt two cannelures, and two cannelures are 180 degree, as adopt three cannelures, are 60 degree between three cannelures respectively, and cannelure is uniform along circumferential direction, avoids the influence of cannelure to nail body intensity, and makes the nail body evenly stressed.
Described cannelure is half-cylindrical, in semi-cylindrical cannelure, be provided with the tantalum post and with the cylindrical of described thread inscribe mutually, described tantalum metal layer is positioned at the outside of tantalum post.Adding man-hour, the semi-cylindrical cannelure that can be earlier on the nail body, spud in, again with the tantalum column filling in cannelure, at the outer surface processing thread of nail body, can make the thread of being processed more regular again by this structure, avoid the be eager to excel influence of degree of synthetism.
The matrix of described nail body is that titanium alloy material is made, and described tantalum metal layer is a porous nano tantalum cladding layer.The nanometer tantalum layer combines with the titanium alloy layer alloying, improves the compatibility of nail body and osteocyte, and healing time is short, healing intensity height.
On described nail tail, be provided with screw grooves or screw base station.When the nail tail is provided with screw grooves, can be used as uses such as pedicle nail, when the nail tail is provided with base station, artificial tooth can be set on base station.
In sum, advantage of the present invention is: biological activity of the present invention is good, can make bone grow into, promote bone to integrate, and healing time is short, healing intensity height.

The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated:
Embodiment one
As shown in Figure 1, a kind of synthetism of processus styloideus radii conformability nail comprises nail body 1 and nail tail 2, and the outer surface at nail body 1 is provided with tantalum metal layer 5 at least.
Wherein, be provided with screw grooves 7 on nail tail 2, be provided with thread 3 on described nail body 1, be provided with cannelure 4 in the marginal portion of described nail body 1, described tantalum metal layer 5 is located in this cannelure 4; The matrix of described nail body is that titanium alloy material is made, and described tantalum metal layer 5 is a porous nano tantalum cladding layer.
Because tantalum metal layer 5 has excellent biological compatibility and chemical stability, tantalum metal layer 5 is located at the surface that synthetism is followed closely, can induce the growth of bone, shorten the symphysis time, improve symphysis intensity.
Embodiment two
As shown in Figure 2, in the present embodiment, described cannelure 4 is two, along described ailhead circumferentially uniform (promptly two cannelures 4 are 180 degree with respect to the center of circle of following closely body 1); Described cannelure 4 is half-cylindrical, in semi-cylindrical cannelure 4, be provided with tantalum post 6 and with the cylindrical of described thread 3 inscribe mutually, described tantalum metal layer 5 is positioned at the outside of tantalum post 6.Adding man-hour, the semi-cylindrical cannelure 4 that can spud on nail body 1 earlier is filled in tantalum post 6 in the cannelure 4 again, at the outer surface processing thread 3 of nail body 1, can make the thread of being processed 3 more regular by this structure again, avoids the influence that synthetism is eager to excel and is spent.
Embodiment three
As shown in Figure 3, in the present embodiment, described cannelure 4 is three, and three cannelures 4 are 120 degree with respect to the center of circle of following closely body 1.
Embodiment four
As shown in Figure 4, in the present embodiment, on nail tail 2, be provided with screw base station 8, artificial tooth 9 is installed on the screw base station.
Be specific embodiments of the invention only below, do not limit protection scope of the present invention with this; Any replacement and the improvement done on the basis of not violating the present invention's design all belong to protection scope of the present invention.
