The specific embodiment
Embodiment 1
As shown in Figure 1 to Figure 3, a kind of portable fracture locking external fixer of this utility model comprises body frame bar 1 and a plurality of locking pin 2 made by carbon fibre material.Carbon fibre material rigidity is high, and is lightweight, and can see through x-ray.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 the 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 first symmetrical 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, 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 horizontal level of the first oblique tapped through hole A and 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 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.By each locking pin 2 stage casing external screw thread 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 installed on the body frame bar 1.The taper self tapping of individual locking pin 2 is used for the fixing human bone from the 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.
Present embodiment is with the difference part of embodiment 1: 1, use size identical the 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 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, in order 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 among the embodiment 1.
As shown in Figure 4 and Figure 5, 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, perhaps the first body frame bar 1-1 and the second body frame bar 1-2 mode of partially overlapping are symmetrical arranged, at this moment, locking pin 2 can be installed on the spiral through hole of the coincidence of the first body frame bar 1-1 and the second body frame bar 1-2 and non-coincidence part, 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 fixing the first body frame bar 1-1 and the second body frame bar 1-2 relative position.
The portable fracture of this utility model locks external fixer in use, and locking pin 2 can directly be squeezed into sclerotin through medical electric drill, needing to have avoided the complicated procedures such as boring, tapping in the past.Each locking pin 2 is also not identical 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 is all identical with the diameter of each tapped through hole on the body frame bar 1, both guarantee the constant intensity between locking pin 2 and the body frame bar 1, be applicable to again the needs of different parts fracture fixation.The cross section is that half elliptic body frame bar 1 has made things convenient for the fixing of locking pin, locking pin 2 through on the body frame bar 1 vertically squeeze into human bone to tapped through hole or oblique tapped through hole after directly lock with body frame bar 1, both improve resistance to plucking and gone out stress, simplified again component parts, operate simple and easyly, easy to use, avoided the in the past situation of external fixer complex structure, complex operation.Body frame bar 1 can use two modes that are used, and Formation cross-section is complete oval-shaped integral body, and is fixedly connected with by locking pin 2.
This utility model building block is few, operates simple and easyly, is connected and installed conveniently, and is practical, satisfied the demand that war and field emergency use.
