Fixator, rationally, structure is simple for design, is easy to use, the good fixing effect of finger, can effectively prevent generation position at sufferer
It moves, shortens and restore the period, promote therapeutic effect.
A kind of second metacarpal bone spiral fracture fixator described in the utility model includes that wrist fixed cylinder, index finger are fixed
Cylinder, thumb fixed cylinder, connecting shaft and locating rod, the wrist fixed cylinder include arc panel A and arc panel B, arc panel A's
One end is hinged by one end of hinge and arc panel B, and the arc panel A is respectively arranged with the other end of arc panel B to be connect
Plate, two connecting plates are connected by fastening bolt, and the structure and above-mentioned wrist of the index finger fixed cylinder and thumb fixed cylinder are solid
The structure of safety barrel is identical, is fixedly connected with locating rod in wrist fixed cylinder at position corresponding with second metacarpal bone, locating rod with
Index finger fixed cylinder is fixedly connected, and is also fixedly connected with centainly at position corresponding with first metacarpal bone in the wrist fixed cylinder
Position bar, the locating rod are fixedly connected with thumb fixed cylinder.
A kind of second metacarpal bone spiral fracture fixator described in the utility model, rationally, structure is simple, convenient for making for design
With the good fixing effect of finger can effectively prevent and be subjected to displacement at sufferer, shortens and restores the period, promote therapeutic effect.
