Abstract
The utility model relates to an ulna and radius fracture and dislocation traction reduction device. In skeletal injuries of a crus, when both the tibia and the fibula are fractured, the traditional manual method requires at least two persons for operation and is very toilsome, and most traction reduction devices in the market are universal instruments and are worse in pertinence. The ulna and radius fracture and dislocation traction reduction device comprises two traction pipes, an adjusting mechanism and two elastic joint fixing rings; the traction pipes includes a first traction pipe and a second traction pipe; the adjusting mechanism comprises a plurality of ratchet pawls and a screw rod; the ratchet pawls are fixed in the pipe cavity of the first traction pipe; trapezoidal threads are arranged at the screw part of the screw rod, and the tail end of the screw rod is fixed in the pipe cavity of the second traction pipe; the trapezoidal threads at the front ends are clamped on the ratchet pawl; the two elastic joint fixing rings are arranged at the tail ends of the first traction pipe and the second traction pipe respectively. The ulna and radius fracture and dislocation traction reduction device is simple in structure, low in cost, convenient to operate and flexible in adjustment, and is particularly suitable for traction reduction of ulna and radius fracture and dislocation.
Description
Technical field
This utility model relates to a kind of orthopedic medical device, particularly a kind of tibia, fibula double fracture dislocation traction resetting device.
Background technology
In the shank orthopedics injuries, when tibia, fibula all fracture, be easy to occur the dislocation of section bone, when physics docking or operation, all need first the knochenbruch of dislocation to be pulled open and resets by traction, be for further processing, traditional treatment method is by manually pulling open again, and this method at least needs two people to be operated, and require great effort very much, some traction resetting devices also occurred on the market now, but mostly be universal apparatus, specific aim is poor.
The utility model content
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of tibia, fibula double fracture dislocation traction resetting device are provided.
For solving the problems of the technologies described above, this tibia, fibula double fracture dislocation traction resetting device comprise two traction tubes, a governor motion and two elastic joint retainer rings, described traction tube comprises the first traction tube and the second traction tube, described governor motion comprises some ratchets and a screw mandrel, described ratchet is fixed in the first traction tube tube chamber, the silk section of described screw mandrel is trapezoidal silk, the screw mandrel end is fixed in the second traction tube tube chamber, the trapezoidal silk of front end is stuck on ratchet, and described two elastic joint retainer rings are separately positioned on the first traction tube and the second traction tube end.
So design, utilize two elastic joint retainer rings to be separately fixed at ankle joint and knee joint, changes the relative distance of two traction tubes by governor motion, carrys out the length of regulating and controlling device by the relative position of ratchet clamping screw mandrel, realizes the reduction by traction of knochenbruch.
As optimization, described the first traction tube is provided with fastening positioning screw.
As optimization, described the first traction tube and the second traction tube pipe for can mutually being socketed.
As optimization, it is 80～100mm that described screw mandrel exposes the outer length of the second traction tube.
A kind of tibia of this utility model, fibula double fracture misplace, and traction resetting device is simple in structure, with low cost, easy to operate, flexible adjustment, is particularly useful for the reduction by traction of tibia, the dislocation of fibula double fracture.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, a kind of tibia of this utility model, fibula double fracture dislocation traction resetting device are described further:
Fig. 1 is the perspective view of this tibia, fibula double fracture dislocation traction resetting device;
Fig. 2 is the main view plane structural representation of this tibia, fibula double fracture dislocation traction resetting device;
Fig. 3 is the part section structural representation (along vertical bisector plane rip cutting) of this tibia, fibula double fracture dislocation traction resetting device.
In figure: 1-traction tube, 2-governor motion, 3-elastic joint retainer ring, 4-the first traction tube, 5-the second traction tube, 6-ratchet, 7-screw mandrel, the fastening positioning screw of 8-.
The specific embodiment
As Figure 1-3, this tibia, fibula double fracture dislocation traction resetting device comprise two traction tubes 1, a governor motion 2 and two elastic joint retainer rings 3, described traction tube 1 comprises the first traction tube 4 and the second traction tube 5, described governor motion 2 comprises some ratchets 6 and a screw mandrel 7, described ratchet 6 is fixed in the first traction tube 4 tube chambers, the silk section of described screw mandrel 7 is trapezoidal silk, screw mandrel 7 ends are fixed in the second traction tube 5 tube chambers, the trapezoidal silk of front end is stuck on ratchet 6, and described two elastic joint retainer rings 3 are separately positioned on the first traction tube 4 and the second traction tube 5 ends.
Described the first traction tube 1 is provided with fastening positioning screw 8.Described the first traction tube 4 and the pipe of the second traction tube 5 for can mutually being socketed.It is 80～100mm that described screw mandrel 7 exposes the second traction tube 4 outer length.
This utility model includes but not limited to above-mentioned embodiment, and any product that meets the description of these claims, within all falling into protection domain of the present utility model.
