Abstract
The utility model belongs to a clinical therapeutic instrument for a department of orthopedics. The front end of a fixer is provided with two symmetrical arc-shaped crab clamps, and the head part of the crab clamp is in a tip-shaped structure. A juncture of a fixer body and the crab clamps is connected with two movable connecting rods which are symmetrical, the back end of each of the movably connecting rods is connected with a spiral leading screw, both ends of each of the connecting rods penetrated through by the spiral leading screw are hinged with the back end of the fixer body, and a nut for adjusting pressure is arranged on the leading screw. The utility model has the advantages of simple and reasonable structural design and convenient operation, and therefore, the utility model is favorable for fixing and healing after fractures restore positions.
Description
This utility model belongs to orthopaedics clinical treatment apparatus, mainly proposes a kind of link-type fracture external fixator that can be used for oblique type fracture.
Be used for the external fixator of clinical fracture now, have polytype.The folder formula external fixator that is used for oblique type fractures, its front end be two and symmetricly be circular arc and head is the fixation clamp of pointed structure, and the pin portion of circular arc fixation clamp front end thrusts behind the fracture site by adding press fit in use.The pressing mechanism particular importance of this kind holder will be adjusted involutory degree of circular arc clevis and will guarantee stable after fixing by it, but it is adjusted pressing mechanism and still lacks comparatively ideal structural design at present.
The purpose that the utility model proposes the link-type fracture external fixator promptly is further to improve its pressurization guiding mechanism, thereby improves the treatment of fractures effect.
This utility model is finished the technical scheme that its invention task takes: the holder front end has two symmetric circular arc Eriocheir sinensiss folders, Eriocheir sinensis chuck portion is pointed structure, the intersection of retainer body and circular arc Eriocheir sinensis folder is connected with symmetric two movable rods, and two movable rod rear ends are connected with screw.The connecting rod two ends that screw passes are hinged with the retainer body rear end respectively.The nut of regulating circular arc Eriocheir sinensis folder folding degree is arranged on the screw.
This utility model is applicable to unstable fractures such as extremity are long tiltedly, short tiltedly, spiral, but clamping humerus, chi are scratched bone, tibia, femur.Make the reduction of the fracture under perspective, arrive the leading screw end adjusting the nut pine, holder front end folder portion promptly struts, and finds two bites after the reduction of the fracture accurately, fixation clamp is set up in sterilization anesthesia, tightens the adjustment nut, can fracture site is firmly fixing, fracture into the angle for preventing it, small splints fixation is arranged outward.
Structural design of the present utility model is comparatively reasonable, and especially the pressurization guiding mechanism of holder adopts link rod structure, and is comparatively unique and simple, can be by the fixing involutory degree that needs to adjust the circular arc clevis, and easy to operate, help the healing of fracture site.
Embodiment:
Accompanying drawing 1 is this utility model structural representation.
Accompanying drawing 2 is the vertical view of Fig. 1.
With reference to accompanying drawing its structure is further specified:
As shown in drawings: the holder front end has two symmetric circular arc Eriocheir sinensis folders 3, Eriocheir sinensis chuck portion is pointed structure, retainer body 5 is connected with symmetric two movable rods 4 with the intersection of circular arc Eriocheir sinensis folder, two movable rod rear ends are connected with screw 2, connecting rod 6 two ends are hinged with retainer body 5 rear ends respectively, but constitute the bascule of retainer body folding.Screw 2 passes the medium pore of connecting rod 6, and its rear end is equipped with adjusting nut 1.7 is bearing pin among the figure.Connecting rod 6 is square structure with retainer body 5 cross sections, and enough strength clamping fracture are arranged.Circular arc Eriocheir sinensis folder cross section is a cylinder, and head end is pointed, circular arc Eriocheir sinensis folder 3 be structure as a whole with holder body 5 and the two between become 35 ° of angles, be convenient to installation and carry.Material adopts stainless steel, and its corrosion resistance and histocompatibility meet national medical apparatus and instruments requirement standard.
