The specific embodiment
Embodiment 1
As shown in Figure 1 to Figure 3, a kind of portable outside fixed frame for external osteosynthesis of the present invention, comprises body frame bar 1 and a plurality of locking pin 2 by carbon fibre material, made.Carbon fibre material rigidity is high, lightweight, and can see through x-ray.The long 20cm of body frame bar 1, wide 2cm, high 1.5cm, cross section is half elliptic.The body of rod stage casing of body frame bar 1 have evenly distributed nine vertically to tapped through hole D, these nine vertical direction and body frame bars to tapped through hole D move towards perpendicular and are positioned on the line of symmetry of body frame bar 1, these nine vertically to spacing 1.5cm between adjacent two in tapped through hole D, and two of outermost end vertically to the corresponding end outer rims of tapped through hole D and body frame bar 1 4cm apart.The body of rod two ends of body frame bar 1 all have the first symmetrical oblique tapped through hole A, the second oblique tapped through hole B and the 3rd oblique tapped through hole C, between three at a distance of 1cm, the first oblique tapped through hole A, direction and the body frame bar 1 of the second oblique tapped through hole B and the 3rd oblique tapped through hole C move towards oblique, be in triangular distribution and towards not parallel mutually, specifically: the first oblique tapped through hole A is positioned at outward-dipping 10 ° of body of rod outermost end and centerline hole, upper end and centerline hole that the second oblique tapped through hole B is positioned at the body of rod slope inwardly 5 °, the body of rod lower end of the 3rd oblique tapped through hole C between the first oblique tapped through hole A and the horizontal level of the second oblique tapped through hole B, the centerline hole of the 3rd oblique tapped through hole C slopes inwardly 5 °.Nine vertical diameters to tapped through hole D and the first oblique tapped through hole A, the second oblique tapped through hole B and the 3rd oblique tapped through hole C are 5mm.
The stage casing of locking pin 2 is provided with and the external screw thread vertically matching to tapped through hole or oblique tapped through hole, and one end of locking pin 2 is that taper self tapping is from drill point head.By each locking pin 2 stage casing external screw threads with corresponding nine vertically to the threaded engagement of tapped through hole D and the first oblique tapped through hole A, the second oblique tapped through hole B and the 3rd oblique tapped through hole C, locking pin 2 lockings are arranged on body frame bar 1.The taper self tapping of individual locking pin 2 is used for fixing human bone from drill point head.Each locking pin 2 as required difference of fixing brothers, upper limb or lower limb has three kinds of models (i.e. No. 1 pin, No. 2 pins and No. 3 pins), its stage casing diameter is 5mm, and its needle body total length, stage casing external thread length and taper self tapping are respectively from drill point head end length: No. 1 pin: 10cm, 1.5cm, 3mm; No. 2 pin: 15cm, 2.5cm, 4mm; No. 3 pin: 20m, 3.5cm, 5mm.
Embodiment 2
The present embodiment is with the difference part of embodiment 1: 1, use the first body frame bar 1-1 and the second body frame bar 1-2 that size is identical, when the first body frame bar 1-1 and the second body frame bar 1-2 are symmetrical arranged up and down, upper each the corresponding tapped through hole of the first body frame bar 1-1 and the second body frame bar 1-2 connects mutually, to same locking pin 2 is installed.2, for increasing by two body frame bars frictional force each other, the plane surface that the first body frame bar 1-1 and the second body frame bar 1-2 have is matsurface.The parameter of the first body frame bar 1-1 and the second body frame bar 1-2 and locking pin 2 is all identical with relevant parameter in embodiment 1.
As shown in Figure 4 and Figure 5, the present embodiment in use, can be according to the needs of constant intensity and/or regular length, the first body frame bar 1-1 and the complete coincidence system of the second body frame bar 1-2 are symmetrical arranged, or the first body frame bar 1-1 and the second body frame bar 1-2 mode of partially overlapping are symmetrical arranged, now, locking pin 2 can be arranged on the first body frame bar 1-1 and the second coincidence of body frame bar 1-2 and the spiral through hole of non-coincidence part, be positioned at locking pin 2 in the intersection of the first body frame bar 1-1 and the second body frame bar 1-2 when playing fixing human bone, also play the effect of fixing the first body frame bar 1-1 and the second body frame bar 1-2 relative position.
In use, locking pin 2 can directly be squeezed into sclerotin through medical electric drill to the portable outside fixed frame for external osteosynthesis of the present invention, has avoided needing the complicated procedures such as boring, tapping in the past.The model size that each locking pin 2 designs according to different fracture sites is also not identical, but it is all identical with the diameter of each tapped through hole on body frame bar 1 that its main part is especially provided with the diameter of externally threaded stage casing part, both guarantee the constant intensity between locking pin 2 and body frame bar 1, be applicable to again the needs of different parts fracture fixation.Cross section is that half elliptic body frame bar 1 has facilitated the fixing of locking pin, locking pin 2 through on body frame bar 1 vertically to tapped through hole or oblique tapped through hole, squeeze into human bone after directly lock with body frame bar 1, both improve resistance to plucking and gone out stress, simplified again component parts, operate simple and easy, easy to usely, avoided the situation of external fixer complex structure, complex operation in the past.Body frame bar 1 can use two modes that are used in conjunction with, and Formation cross-section is complete oval-shaped integral body, and is fixedly connected with by locking pin 2.
Building block of the present invention is few, operates simple and easyly, is connected and installed conveniently, practical, has met the demand that war and field emergency are used.
