Abstract
The utility model relates to a single-side adjustable external fixer for fracture. Axial grooves (2) are arranged on bolts (1); a plurality of bolts (1) are positioned in sliding grooves (4) of a fixing frame (3); steel needles (5) are inserted in the grooves (2) and fixed by nuts (6); flat gaskets or inclined gaskets (7) are arranged between bolts (1) and steel needles (5).
Description
This utility model belongs to the Orthopeadic Surgery medical apparatus and instruments.
The conventional treatments of fracture is that material large tracts of land such as Gypsum Fibrosum, clamping plate are fixed on fracture, or adopts steel plate, screw bone to be analysed carry out internal fixation, and all there is shortcoming significantly in these methods; Generally adopt the non-operative treatment apparatus of external fixator at present both at home and abroad as fracture, Buddhist nun's (Bastiani) apparatus and Chinese patent CN85200828u and CN86200021u etc. as Huffman (Hoffmann) apparatus, Wagner (Wagner) apparatus and Bath, but these apparatuses or complex structure or poor stability, or degree of regulation is little.
The purpose of this utility model provides a kind of simple in structure, good stability, easy to operate one-sided adjustable fracture external fixator.
This utility model (being embodiment) is achieved in that and has axial groove 2 on the bolt 1, several bolts 1 are arranged in the sliding tray 4 of fixed mount 3, fix in draw point 5 insertion grooves 2 and by nut 6, be lined with one or several packing rings 7 between bolt 1 and the draw point 5, packing ring 7 is divided into faced washer and inclined-plane packing ring.
Fixed mount 3 can adopt aluminum alloy materials to make, and other parts all adopt stainless steel material to make, and the epiphysis that advances of draw point 5 has screw thread.
During use, the epiphysis that advances of draw point 5 is fixed in the bone, in the other end insertion groove 2, pass through fixedly draw point 5 of nut 6 then, swivel bolt 1 rectifiable fracture side angulation displacement, adjust the front and back angulation displacement of the rectifiable fracture of different-thickness of two draw point packing rings 7 of same fracture segment, adjust the same thickness or the lateral displacement that enter the degree of depth rectifiable fracture of draw point 5 in bolt 1 of two draw point packing rings 7 of same fracture segment, the rectifiable rotation displacement of inclined-plane packing ring.
The utlity model has simple in structure, good stability, easy to operate advantage, especially bolt 1 moves flexibly in fixed mount 3, so the entry point of draw point 5 is unrestricted, can correct the partial fracture displacement by adjusting bolt 1 and packing ring 7 simultaneously.
Accompanying drawing 1 is this utility model structural representation.
Accompanying drawing 2 is this utility model user mode sketch map.
Among the figure: 1-bolt, 2-groove, 3-fixed mount, 4-sliding tray, 5-draw point, 6-nut, 7-packing ring.
Claims (2)
1, one-sided adjustable fracture external fixator is characterized in that having on the bolt (1) axial groove (2), and several bolts (1) are arranged in the sliding tray (4) of fixed mount (3), fixes in draw point (5) insertion groove (2) and by nut (6).
2, by the described one-sided adjustable fracture external fixator of claim 1, it is characterized in that being lined with one or several packing rings (7) between bolt (1) and the draw point (5), packing ring (7) is divided into faced washer and inclined-plane packing ring.
