The present invention is with reference to the design of Hoffman-II type, and the most fixing pin have employed the fixed form of two one group, but
The mode that shank connection, bar bar connect improves, and redesigns fixing pin: 1. laterally fix pin and for two
The short vertical pole of root forms one group, and shank is connected by the special bayonet socket of designed, designed and fixes, and the convenient fixing making bayonet socket is simple；②
Being connected two groups of short vertical poles by the vertical pole of a root length, form whole external fixer, bar bar is connected by the special bayonet socket of designed, designed
Fixing, the convenient fixing making bayonet socket is simple, and can not be fixed in the case of same plane at two groups of short vertical poles, reduces
Operation easier is fixing with adaptation trans-articular；The most each group of backshank fixing pin uses bayonet type to contact with electric drill, the side of electric drill
Just install and remove, reducing the operating time for operation process；4. fix pin front and use the Schanz screw of self-tapping type, can
Directly screwed in by electric drill, reduce operation sequence；5. increase simple sleeve, during preventing from screwing in fixing pin, too much damage
Hinder pinprick surrounding soft tissue.
2) design requirement is followed that treatment of war wound is quick, easy, is prone to grasp operation, profile is light and handy, fixed is easy to
After the principle sent: 1. shank bayonet socket and the fixing of bar bar bayonet socket can be quickly completed, and operate without other aids, and
Fixing reliable really, even if fixing in the case of between pin, span is relatively big at two groups, fixing axle remains to bear bigger strength；
2. the design of bar bar bayonet socket can ensure also can quickly finish effective bar bar in the case of two groups of quarter butts form the bigger angle of cut
Connect；3. the front end fixing pin requires energy during low speed pierces from brill, tapping screw thread design, and the diameter design of pin
Prevent splitting and other damages of sclerotin, its requirement of strength can be met simultaneously；4. according to different parts, design and meet each
Position (forearm, upper arm, thigh, shank, across elbow joint, across knee joint, across ankle joint etc.) fixing war wound extenal fixation
Frame vertical pole diameter, fixing pin diameter and the model of bayonet socket.
3) related experiment of complete design and Biomechanics test carry out the biomechanics experiment of cadaver sample, mainly for
Lower parameter: 1. the most whole external fixer of Biomechanics test of the Biomechanics test of shank bayonet socket 2. bar bar bayonet socket connects
After completing, 4. the Biomechanics test of each connecting portion fixes the related assays of pin diameter, the depth of thread, pin length etc.,
Obtain optimal mechanics effect and sclerotin splitting 5. other biomechanical data can be prevented.
Experiment proves the external fixer in wartime that the present invention provides, and mechanical property is excellent, and good fixing effect.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed fortune
With, it can be applied to various applicable the field of the invention completely, for those skilled in the art, and can be easily
Realizing other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details with shown here as the legend with description.
