Inner fixer of the present utility model catches on anterior superior iliac spine by hook portion, and anterior superior iliac spine is fixed by portion by the arm of force, whole fixation procedure is very rapid, operates very simple, fixing very firm, stable, and need not to hole by epiphysis, can not cause secondary damage to epiphysis.
As preferably, described hook portion comprises two circular arc hook plates, is provided with groove between described two circular arc hook plates.
Adopt two circular arc hook plates corresponding with skeletal shape, fixed effect is fine, and is provided with groove between the hook plate, makes hook portion and fracture site contact surface avoid damaging tendon less.
As preferably, described arm of force portion comprises at least two card articles that tilt to described hook portion direction.
Arm of force portion adopts the form of inclination card article, can when in use the inclination card article be put into 0 ℃ environment, then the inclination card article be bent, make the inclination card article become 90-95 ° of angle with body, holing at ilium in the back, location, inserts arm of force portion bone fixation folding position, then by 35 ° of warm saline flushings, the restoring force that is produced by the memorial alloy self-characteristic pressurizes to fracture end and forms different cambers with body, bone fixation folding position to greatest extent, good fixing effect, very firm.
As preferably, described inclination card article becomes 20-35 ° of angle with described body.
Above-mentioned angle setting, good fixing effect.
As preferably, described inclination card article is provided with the tooth that extends to described body direction.
The fixed effect of inclination card article and skeleton is further strengthened in the existence of tooth, prevents from getting loose, and is fixing very firm, stable.
As preferably, described tooth becomes 15-30 ° of angle with described inclination card article.
Effective at above-mentioned angular range internal fixation.
As preferably, described body two sides are the arc surface that caves inward.
Adopt the arc surface of sunken inside, not only reduced the materials of body, and satisfied under the prerequisite of structural strength, make body be convenient to bending and skeleton fits, make good fixing effect.
As preferably, described body is that thickness is the connecting plate of 3mm.
Adopt the form of connecting plate, be convenient to make and bending, be conducive to improve the fixed effect of whole inner fixer.
As preferably, described body, hook portion and arm of force portion is one-body molded makes.
Adopt integrated mode to make, process velocity is fast, quality good.
Compared with prior art, advantage of the present utility model is: the structure that has taken into full account anterior superior iliac spine, by the holder that adopts medical Ultimum Ti material to make, can avoid that internal fixation is loosening, the generation of situations such as fracture and bone does not connect, avoid skeleton is caused secondary damage, simple to operate, shortening operating time can produce sustained stress to fracture end and promote union of fracture.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further:
Fig. 1 is the structural representation of this utility model one embodiment;
Fig. 2 is fixedly sketch map of Fig. 1 arm of force portion bending.
Among the figure:
The 1-hook portion;
The 2-body;
The 21-sides of body;
3-arm of force portion;
The 31-tooth.
The specific embodiment
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1,2, a kind of anterior superior iliac spine inner fixer that resets, the arm of force portion of being made by memorial alloy that comprises that body, the hook portion that is connected with described body one end and the described body other end connect.In the present embodiment, described body, hook portion and arm of force portion are one-body molded, make by memorial alloy, and arm of force portion and hook portion are to relative direction bending.
Described hook portion comprises two circular arc hook plates, is provided with groove between described two circular arc hook plates.The curved transition in the junction of described hook portion and described body.The hook portion top is arc surface, and this arc surface is linked to be by the arc transiting surface of a plurality of angles.
Described arm of force portion comprises at least two inclination card articles that tilt to described hook portion direction.In order to strengthen fixed effect, arm of force portion can also comprise three or four inclination card articles that tilt to described hook portion direction.Described inclination card article is provided with the tooth that extends to described body direction.Described inclination card article becomes 20-35 ° of angle with described body, card article was better with the fixed effect of fracture position when described inclination card article became 25 ° of angles with described body.Described tooth becomes 15-30 ° of angle with described inclination card article, and when described tooth became 20 ° of angles with described inclination card article, card article was better with the fixed effect of fracture position.Described body two sides are the arc surface that caves inward.
At first the anterior superior iliac spine inner fixer is placed under 0 ° of environment in the art, a plurality of inclination card articles of arm of force portion and the angle of body are converted into 90-95 °, then hook portion is launched to be fixed on the free bone piece due to the fracture, after resetting arm of force portion and ala of ilium contact point are holed, and the arm of force deployed in the hand-hole, then with 35 ° of warm saline flushings, finally the restoring force that is produced by the memorial alloy self-characteristic is to the fracture end internal fixation that pressurizes, the angle of arm inclination card article and body of exerting all one's strength is returned to 25 ° of initial angles, tooth on the card article simultaneously tilts, the fixing of arm and human fracture end of further exerting all one's strength is more firm, prevents from becoming flexible.When the angle of the inclination card article of arm of force portion and body was replied initial angle, the body two sides caved inward, and are fitted to greatest extent in body and duverney fracture position, the fixedly fastness of increase inner fixer.
More than explanation only is to explanation of the present utility model, make enforcement this programme that those of ordinary skills can be complete, but be not to restriction of the present utility model, those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this description, these all are not creative modifications.But as long as in claim scope of the present utility model, all be subjected to the protection of Patent Law.
