Description
Technical field
It is especially a kind of for fracture convalescence or lopsided phalanges correction the invention belongs to the field of medical instrument technology
Finger miniature external fixing rack.
Background technology
Currently, following 3 requirements should be reached to hand fractures principle：(1) make every effort to anatomical reduction；(2) light and firm
Solid fixation；(3) early ambulant and functional exercise.It is clinical mainly to treat phalangeal fracture using following three kinds of modes at present.First
It is fixed in kind Kirschner wire.It is always the treatment most common method of fracture of metacarpal bone and phalanges of fingers because its is easy to operate, inexpensive, but the disadvantage is that
Stability maintenance is poor, and the bad processing of intra-articular fracture need to often cut interior fixation；It is fixed in second of miniature steel plate or screw.It is micro-
Shape steel plate is superior to other internal fixation methods in terms of surface rigidity, the stability of fracture site and union.But miniature steel
Plate it is fixed the disadvantage is that must open reduction, it is big to damaging surrounding tissue, be unfavorable for the healing of fracture, it is costly, and exist
Second operation takes out interior fixed problem.The fracture and intra-articular fracture far saved in tend not to apply or application effect not
It is good；The third phalanges external fixator phalangeal fracture.Its advantage：External fixator is simple in structure, and charge and discharge operations, fracture is convenient for be cured
After conjunction, interior fixation is removed without second operation, convenient for movable fracture site lower articular as early as possible, prevents anchylosis, hand function
Restore early, better function.It is at present imported product using external fixator in clinic, common ground is fixed for single armed, expensive,
Complicated for operation, fixing glue often by finger back side or the merging of back of the body outside, is easy to damage tendon, causes adhesion of tendon.
Invention content
For overcome the deficiencies in the prior art, the present invention provides a kind of finger miniature external fixing rack, which has
Operation is easy, both arms fixed traction is not easy to shift and has the reseting fracture position from stereo directional, and reaches continuous traction
Effect.
