Nut is connected with, described nut is rotatablely connected with drawing pedestal inner end.
Further, there is the guide groove of axial direction on described screw rod, pull and be provided with pedestal in embedded guide groove
Guide finger, prevent screw rod from producing rotation by guide finger effect.
Described drawing pedestal inner end has the cavity coordinated with nut gap, and nut periphery offers circumferential recess,
Position-limitting pin is installed into the circumferential recess from drawing pedestal inner end, acting on nut by position-limitting pin can only turn
Move and limit the axial movement of nut.
There is the neck for being caught in the connecting rod to simplify structure, on described drawing pedestal, drawing pedestal provided with from
The clamping screw of neck clamping sides connecting rod.
Drawing steel wire is adjusted for convenience of changing, described drawing steel wire is pressed on fixed pedestal by lock screw.
The beneficial effects of the invention are as follows：The present invention can make full use of the internal space of exterior fixing rack, in processing fracture
The problem of handling defect of skin simultaneously, coordinated by the transmission between screw rod, nut, the position of flexible modulation skin traction device with
Wound shape is adapted to,, can be with after being closed in advance apart from small wound for the irregular of wound during skin traction
Individually extract the drawing steel wire of the closure surface of a wound out, and the not closed surface of a wound can further be drawn, and adjusted in wound side skin
Save it is bad in the case of remain to use, can also individually pull the good side of edge of wound skin to reduce or close the surface of a wound.
Brief description of the drawings

In figure：1. exterior fixing rack 1-1. connecting rods 2. pull pedestal 2-1. necks 3. and pull the spiral shell of 4. fixed pedestal of steel wire 5.
The lock screw of 6. 9. clamping screw of nut 6-1. circumferential recess 7. guide finger, 8. position-limitting pins of bar 5-1. guide grooves 10.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of skin traction device supporting based on exterior fixing rack as shown in FIG. 1 to 3, the exterior fixing rack 1
Including setting up the connecting rod 1-1 of both sides separately and being connected to the cross bar of connecting rod 1-1 upper and lower sides.
The skin traction device includes：Drawing pedestal 2 on the connecting rod 1-1 of exterior fixing rack 1 can be clamped in, for installing
The fixed pedestal 4 of steel wire 3 is pulled, there is the neck 2-1 for being caught in the connecting rod 1-1 on drawing pedestal 2 therein, pull pedestal
2 are provided with the clamping screw 9 from neck 2-1 clamping sides connecting rods 1-1, and the drawing steel wire 3 with protective case passes through locking screw
Silk 10 is pressed on fixed pedestal 4.
Described drawing pedestal 2 has the endoporus of axial direction, and the inner end of drawing pedestal 2 of the nearly side of fixed pedestal 4 has one
Individual diameter is more than the cavity of endoporus, is equipped with one end in the endoporus of drawing pedestal 2 and passes the cavity and passes through with fixed pedestal 4
The connected screw rod 5 of pin, drawing pedestal 2 inner end side are provided with the nut 6 being threadedly coupled with screw rod 5, and there is nut 6 one to tie
The cavity gap of the rotation section of structure and limiting section, the wherein limiting section of nut 6 and the drawing inner end of pedestal 2 coordinates.
Especially, the limiting section periphery of nut 6 offers circumferential recess 6-1, from the drawing inner end of pedestal 2 to the circumference
The position-limitting pin 8 that the restricted nut 6 of installation moves axially in groove 6-1；Similarly, there is leading for axial direction on described screw rod 5
To groove 5-1, pull the guide finger 7 being provided with pedestal 2 in embedded guide groove 5-1, by the effect of guide finger 7 prevent screw rod 5 with
Nut 6 produces rotation phenomenon when coordinating and moving, and position-limitting pin 8 then prevents from producing axial movement when nut 6 from rotating.
In use, the drawing steel wire 3 pulled in wound skin is pressed abd fixed on fixed pedestal 4 with lock screw 10,
Rotating nut 6 makes screw rod 5 move axially to correct position, and the connecting rod 1-1 of exterior fixing rack 1 is caught on drawing pedestal 2
In neck 2-1, with clamping screw 9 from clamping sides connecting rod 1-1, when skin drawing slowly recovers for a period of time, then
Next suitable drawing position is moved to by the adjusting screw rod 5 of nut 6, continues that skin pull until recovery from illness.If
Tractor need to axially be made to adjust up and down along connecting rod 1-1 during skin drawing, need only unclamp clamping screw 9, will pull
Pedestal 2 axially makees moving for certain distance along connecting rod 1-1, tightens clamping screw 9 after moving into place again.
The present invention can be coordinated according to the shape of wound and pull pedestal 2 by the transmission between screw rod 5 and nut 6
Moved axially along connecting rod 1-1, realize the position of flexible modulation skin traction device to adapt to wound shape；In skin traction
Cheng Zhong, for the irregular of wound, after being closed in advance apart from small wound, it can individually extract the drawing steel wire of the closure surface of a wound out
3, and the remaining not closed surface of a wound can further be drawn, and remain to make in the case where skin regulation in wound side is bad
With can individually pull the good side of edge of wound skin to reduce or close the surface of a wound.This is based on the supporting skin of exterior fixing rack 1
Skin tractor can make full use of the internal space of exterior fixing rack 1, while fracture is handled the problem of processing defect of skin.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
