Abstract
The utility model relates to an adjustable bone tractor which belongs to medical equipment. The adjustable bone tractor has the structure that a traction frame is provided with a hook. The utility model is characterized in that the traction frame is formed by a way that three supporting rods are orderly hinged into a triangle; each supporting rod is composed of screw rods which are spirally connected to both sides of a thread sleeve; the rotating direction of screw threads at both sides of the thread sleeve is opposite; the hook is fixed on an apical angle of the traction frame; draw rods are arranged on two bottom angles of the traction frame. The utility model has the advantages that the variation of the traction direction is continuous, and the utility model is good for the correction of the angulation deformity of the fracture part.
Description
Technical field: this utility model belongs to medical apparatus and instruments, is specifically related to a kind of adjustable bone tractor.
Background technology: the rectification of existing angulation deformity to fracture site is undertaken by traction apparatus, and the structure of traction apparatus is that a plurality of hook towing pads are set on arc support, links up with on support different positions by conversion and adjusts pull strength and lead; Its shortcoming is a trivial operations, and lead changes discontinuous, is unfavorable for the rectification to the angulation deformity of fracture site.
Summary of the invention: the purpose of this utility model provides a kind of simple to operate, but the adjustable bone tractor of lead continually varying.
The technical solution of the utility model is: a kind of adjustable bone tractor, on traction frame, establish hook, and it is characterized in that traction frame links triangularity successively by three poles and constitutes; Pole is made up of the screw rod that is threaded with the swivel nut both sides, and the thread rotary orientation of swivel nut both sides is opposite; Hook is fixed on the drift angle of traction frame, and traction frame is established pull bar on two base angles.
Owing to adopt technique scheme, during use, utilize draw point to pass sclerotin, the draw point two ends are fixed on the pull bar, rotate swivel nut as required, change strut lengths, can adjust lead continuously; Thereby have the lead variation continuously, help the corrigent advantage of fracture site angulation deformity.
Description of drawings: come the technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments.Accompanying drawing is a structural representation of the present utility model.
The specific embodiment: with reference to the accompanying drawings, a kind of adjustable bone tractor is established hook 1 on traction frame, and traction frame links triangularity successively by three poles and constitutes; Pole is made up of the screw rod 3 that is threaded with the swivel nut both sides, and the thread rotary orientation of swivel nut 2 both sides is opposite; Hook 1 is fixed on the drift angle of traction frame, and traction frame is established pull bar 4 on two base angles.During use, the rotation swivel nut changes strut lengths, can adjust lead continuously.
