Description
(1) technical field
The present invention relates to medical instruments field, particularly a kind of bone tractor.
(2) background technology
Bone traction mode conventional after extremity fracture comprises traction and ulna olecranon traction on calcaneal traction, skeletal traction through tibial tubercle, condyle of femur, for stable fracture, corrects cripetura and angulation deformity.Conventional bone tractor need select thicker draw point to prevent draw point when drawing limbs from bending.And draw point is thicker, larger to the damage of soft tissue and skeleton.
(3) summary of the invention
The present invention, in order to make up the defect of prior art, provides a kind of rigidity, the bone tractor that reduces soft tissue and skeleton trauma that increase draw point.
The present invention is achieved through the following technical solutions:
A kind of bone tractor, is characterized in that: comprise the U-shaped structure be made up of the joint of two draft arms and arc, the upper end of described draft arm is provided with draw point fixture, and the lower end of described draft arm is provided with draft arm device for spreading.
Described draft arm device for spreading comprises the leading screw be threaded with a wherein draft arm, and the outer end of described leading screw is provided with turning handle, and the inner of described leading screw and another root draft arm are connected axle turnablely.
Described screw mandrel is only provided with screw thread in the one end be threaded with draft arm.
Described draft arm device for spreading comprise band two nuts threaded rod, with the plane orthogonal at U-shaped structure place strut fixed via, with strut fixed via supporting be strut set bolt and hold-down nut, described in strut set bolt head be provided with the via hole that can hold threaded rod and pass through.
Described draw point fixture comprises the fixed via with the plane orthogonal at U-shaped structure place, with fixed via supporting be set bolt and hold-down nut, the screw rod of described set bolt is provided with steel pinhole.
Described joint is provided with the connector connecting pull rope.
All parts are made by stainless steel material.
Described connector is rustless steel machine leader with holes.
Described connector is towing pad.
The invention has the beneficial effects as follows:
Structure of the present invention is simple, easy to use, is applicable to selecting thinner draw point, reduces soft tissue and skeleton trauma.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Fig. 1 be the first embodiment of the present invention main TV structure schematic diagram;
Fig. 2 be the second embodiment of the present invention main TV structure schematic diagram.
In figure, 1 draft arm, 2 joints, 3 leading screws, 4 turning handles, 5 screw threads, 6 fixed vias, 7 set bolts, 8 hold-down nuts, 9 steel pinholes, 10 machine leaders, 11 towing pads, 12 threaded rods, 13 nuts, 14 strut fixed via, and 15 strut set bolt, 16 via holes.
(5) detailed description of the invention
Accompanying drawing is specific embodiments of the invention.Be illustrated in figure 1 the first embodiment, this kind of bone tractor, all parts are made by stainless steel material, and it comprises the U-shaped structure be made up of the joint 2 of two draft arms 1 and arc, the upper end of draft arm 1 is provided with draw point fixture, and the lower end of draft arm 1 is provided with draft arm device for spreading.
Draft arm device for spreading comprises the leading screw 3 be threaded with a wherein draft arm 1, and the outer end of leading screw 3 is provided with turning handle 4, and the inner of leading screw 3 and another root draft arm 1 are connected axle turnablely: can directly withstand on inside draft arm 1 by leading screw 3; Also can open a blind hole inside draft arm 1, the end of leading screw 3 withstands in blind hole; Can also be hinged on draft arm 1 by the end of leading screw 3, also can be the method that other known leading screw 3 axles turn; Pass draft arm 1 for convenience of by leading screw 3, screw mandrel is only provided with screw thread 5 in the one end be threaded with draft arm 1.
Draw point fixture comprises the fixed via 6 with the plane orthogonal at U-shaped structure place, with fixed via 6 supporting be set bolt 7 and hold-down nut 8, the screw rod of set bolt 7 is provided with steel pinhole 9, and this steel pinhole 9 can hold draw point and pass.
Joint 2 is provided with the connector connecting pull rope, and this connector can be machine leader 10 with holes as shown in Figure 1, also can be a towing pad 11 as shown in Figure 2; Machine leader 10 can be fixed on joint 2, also can be hinged on joint 2; Also can be other modes, such as fasten the ring etc. on joint 2; No matter be towing pad 11 or machine leader 10, be all positioned at the middle part in joint 2.
Figure 2 shows that the second embodiment, draft arm device for spreading is only with the difference of the first embodiment, this draft arm device for spreading comprises a threaded rod 12, with two nuts 13 on threaded rod 12, draft arm 1 has with the plane orthogonal at U-shaped structure place strut fixed via 14, with strut fixed via 14 supporting be strut set bolt 15 and hold-down nut 8, the head strutting set bolt 15 is cross section is polygonal cylinder, has the via hole 16 that can hold threaded rod 12 and pass through above it.
During use, by draw point through the two ends after skeleton, set bolt 7 being through draw point, after set bolt 7 being inserted the fixed via 6 of draft arm 1 upper end, tighten hold-down nut 8, such draw point has just been fixed, in a first embodiment, leading screw 3 withstood on another draft arm 1 through after draft arm 1, being rotated further turning handle 4 can distraction arm 1; In the second embodiment, be through on the two ends of threaded rod 12 by strutting set bolt 15, now two nuts strut the inner side of set bolt 15 at two, fixed via 14 is strutted by what strut that set bolt 157 inserts draft arm 1 lower end, tighten hold-down nut 8, the nut turned on threaded rod 12 makes nut be close to the head strutting set bolt 15, then continues to turn nut, can distraction arm 1; Tension draw point while distraction arm 1, according to the drawing tension of degree of crook adjustment to draw point of draw point during Bone traction.After adjusting, pull rope is connected on the hole of towing pad 11 or machine leader 10, just can does Bone traction.
Except technical characteristic described in description, all the other technical characteristics are those skilled in the art's known technology.
