Abstract
The utility model discloses a kind of two enhanced reduction of the fracture devices of class lever kinetic moment, including fixed plate, described fixed plate one end is fixedly connected with the telescopic rod perpendicular to fixed plate, fixed plate close to telescopic rod side is equipped with the threaded hole for passing through screw, and the axis of threaded hole and the telescopic direction of telescopic rod are parallel.The utility model makes one end far from telescopic rod of fixed plate, screw, telescopic rod constitute two class lever constructions, is not used only laborsaving, and can reduce the quantity of the fixing screws on backbone, reduce operating procedure in art, shorten operating time.Reset of the utility model suitable for reduction of the fracture operation, for fracture sites such as humerus head, toe head, fingers.
Description
Technical field
The utility model belongs to the field of medical instrument technology, more particularly to a kind of two enhanced fracture of class lever kinetic moment
Restorer.
Background technique
Traditional reduction of the fracture device is not provided with telescopic rod, using the screw for being fixed on backbone as fulcrum, is fixed by traction
Plate resets bone, and this mode uses more laborious.Application No. is in 200920290843.4 utility model patent
It discloses traction reduction pincers, this reduction forceps in a kind of art and lever principle traction reduction is although utilized, but need to be the two of fracture end
Upper one piece of screw respectively is held, the quantity of fixed thread nail is increased.The operating procedure in art is on the one hand increased in this way, it is another
Aspect increases the damage to bone.
Utility model content
Existing in the prior art above insufficient to solve, the utility model is intended to provide a kind of two class lever kinetic moments
Enhanced reduction of the fracture device is risen by making one end far from telescopic rod of fixed plate, screw, telescopic rod constitute two class lever constructions
To the quantity that can reduce the fixing screws on backbone, operating procedure in art is reduced, the purpose of operating time is shortened.
To achieve the above object, technical solution used by the utility model is as follows: a kind of two class lever kinetic moments increasing
Strong type reduction of the fracture device, including fixed plate, described fixed plate one end are fixedly connected with the telescopic rod perpendicular to fixed plate, close to stretch
The fixed plate of contracting bar side is equipped with the threaded hole for passing through screw, and the axis of threaded hole and the telescopic direction of telescopic rod are parallel.
As the improvement of the utility model, the fixed plate is equipped with multiple threaded holes, the axis of each threaded hole and flexible
The axle center of bar is located along the same line.
Due to the adoption of the above technical solution, compared with prior art, acquired beneficial effect is the utility model:
For the utility model by setting perpendicular to the telescopic rod of fixed plate, dead plate upper end point is power point, and screw is resistance
Force, telescopic rod are fulcrum, and one end far from telescopic rod of fixed plate, screw, telescopic rod is made to constitute two class lever constructions.Such phase
More traditional restorer not only increases power arm, and use is more laborsaving；And telescopic rod can be with fixed link to backbone distance
Reduction and shorten, remain and be in contact with backbone, play the effect of balance pivot.In addition, the utility model can root
According to backbone position, the threaded hole of suitable position in fixed plate is chosen, screw is passed through into threaded hole and is fixed on backbone.And this reality
A screw need to be only fixed on backbone with novel, compared the prior art in background technique, can be reduced the quantity of fixing screws,
Operating procedure in art is reduced, shortens operating time, the damage to bone can also be reduced.
The utility model is suitable for reduction of the fracture operation, for answering for the fracture sites such as humerus head, toe head, finger
Position.
Detailed description of the invention
With reference to the accompanying drawing and specific embodiment makees more detailed description to the utility model.
Fig. 1 is the structural schematic diagram of the utility model embodiment；
In figure: 1, fixed plate；2, telescopic rod；3, threaded hole；4, screw；5, backbone；6, fracture end.
Specific embodiment
Embodiment 1
A kind of two enhanced reduction of the fracture devices of class lever kinetic moment, as shown in Figure 1, include fixed plate 1, telescopic rod 2 and
Screw 4.
1 one end of fixed plate is fixedly connected with telescopic rod 2, and the telescopic direction of telescopic rod 2 is perpendicular to fixed plate 1.Close to flexible
The fixed plate 1 of 2 side of bar is equipped with threaded hole 3, and the axis of threaded hole 3 is parallel with the telescopic direction of telescopic rod 2.Fixed plate 1
Multiple threaded holes 3 are equipped with, the axle center of the axis and telescopic rod 2 of each threaded hole 3 is located along the same line, according to backbone 5 and bone
The relative position at end 6 is rolled over, the threaded hole 3 of suitable position in fixed plate 1 is chosen, screw 4 is passed through into threaded hole 3 and is fixed on backbone 5
On, so that one end, telescopic rod 2 and screw 4 of the fixed plate 1 far from telescopic rod 2 form two class lever constructions.
When using the present embodiment, fixed plate 1 is in contact with fracture end 6, elongation telescopic rod 2 makes telescopic rod and 5 phase of backbone
The threaded hole 3 of suitable position in fixed plate 1 is chosen in contact, and screw 4 is passed through threaded hole 3 and is fixed in backbone 5.Pass through traction
The fixed plate 1 being in contact with fracture end 6 resets fracture end 6 under leverage.
