The specific embodiment
Embodiment 1
To shown in Figure 3, a kind of portable external fixation of fracture frame of the present invention comprises the body frame bar 1 and a plurality of locking pins 2 processed by carbon fibre material like Fig. 1.Carbon fibre material rigidity is high, and is in light weight, and can see through the X line.Body frame bar 1 long 20cm, wide 2cm, high 1.5cm, cross section are 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 are vertically moved towards perpendicular and are positioned on the line of symmetry of body frame bar 1 to the direction of tapped through hole D and body frame bar; These nine vertical spacing 1.5cm between adjacent two in tapped through hole D, two of outermost end vertically to the corresponding end outer rim 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 symmetric first oblique tapped through hole A, the second oblique tapped through hole B and the 3rd oblique tapped through hole C; Between the three at a distance of 1cm; Direction and the body frame bar 1 of the first oblique tapped through hole A, the second oblique tapped through hole B and the 3rd oblique tapped through hole C move towards oblique; Be in triangular distribution and not parallel towards 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 horizontal level of the first oblique tapped through hole A and the second oblique tapped through hole B, and 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 that vertically matches to tapped through hole or oblique tapped through hole, and an end of locking pin 2 is that the taper self tapping is from the drill point head.Through each locking pin 2 stage casing external screw thread and nine corresponding vertical threaded engagement, locking pin 2 lockings are installed on the body frame bar 1 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.The taper self tapping of individual locking pin 2 is used for fixing the human body bone from the drill point head.The difference of the fixed as required brothers of each locking pin 2, 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.
Present embodiment is with the difference part of embodiment 1: 1, use the size identical first body frame bar 1-1 and the second body frame bar 1-2; When the first body frame bar 1-1 and the second body frame bar 1-2 are symmetrical set up and down; The first body frame bar 1-1 and the second body frame bar 1-2 go up each corresponding tapped through hole and connect each other, so that 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 a matsurface.The parameter of the first body frame bar 1-1 and the second body frame bar 1-2 and locking pin 2 all with embodiment 1 in relevant parameter identical.
Like Fig. 4 and shown in Figure 5; Present embodiment in use; Can the first body frame bar 1-1 and the complete coincidence system of the second body frame bar 1-2 be symmetrical set according to the needs of constant intensity and/or regular length, perhaps the first body frame bar 1-1 and the second body frame bar 1-2 mode of partially overlapping be symmetrical set; At this moment; Can locking pin 2 be installed on the spiral through hole of coincidence and non-intersection of the first body frame bar 1-1 and the second body frame bar 1-2, be positioned at locking pin 2 on the intersection of the first body frame bar 1-1 and the second body frame bar 1-2 when playing the fixing human bone, also play the effect of the fixing first body frame bar 1-1 and the second body frame bar 1-2 relative position.
The portable external fixation of fracture frame of the present invention in use, locking pin 2 can directly be squeezed into sclerotin through medical electric drill, needing to have avoided complicated procedures such as boring, tapping in the past.Each locking pin 2 is also inequality according to the model size that different fracture sites design; But the diameter that its main part especially is provided with externally threaded stage casing part all with body frame bar 1 on the diameter of each tapped through hole identical; Both guarantee the constant intensity between locking pin 2 and the body frame bar 1, be applicable to the needs of different parts fracture fixation again.The cross section is that half elliptic body frame bar 1 has made things convenient for the fixing of locking pin; Locking pin 2 is through vertically directly locking with body frame bar 1 after tapped through hole or oblique tapped through hole are squeezed into the human body bone on the body frame bar 1; Both improve resistance to plucking and gone out stress; Simplify component parts again, operated simple and easyly, easy to use, avoided the situation of external fixer complex structure, complex operation in the past.Body frame bar 1 can use two modes that are used, and forming the cross section is complete oval-shaped integral body, and is fixedly connected through locking pin 2.
Building block of the present invention is few, operates simple and easyly, is connected and installed conveniently, and is practical, satisfied the demand of war and field emergency use.
