Description
Technical field
The present invention relates to the reduction units on a kind of human body long bone fracture reduction apparatus, and in particular to a kind of controllable limbs are whole
Multiple unit arranges regulation contraposition for human body limb long bone fracture, belongs to medical instruments field.
Background technique
The treatment method for medically adopting artificial reduction synthetism always in terms for the treatment of long bone of limbs folding at present, mainly there is biography
The operation Plate internal fixiation method of system, splinting, closed-plaster method, traction treatment etc..It is basic to belong to but from the point of view of synthetism operation
In empirical and hand-manipulated, not only large labor intensity, but also, shortage science and accuracy poor to line there is aligning, and
It is completely dependent on the experience and sense of responsibility of attending physician.From the point of view of outer fixation, there is also the fixations after reduction at present not
It needs to bundle when stablizing, and fixing, extends the healing cycle of knochenbruch.From the point of view of inner fixed law, although fixed stability
It is good, but it requires operation horizontal high, need to cut muscle, tendon, push nerve, periosteum aside after followed closely Interal fixation with gong in fractures
Blood circulation is destroyed in position, is easy to happen infection, it is long to restore the period, and need to carry out second operation, increases the pain of patient
And financial burden.Since synthetism is ineffective, disability rate is high, and the especially treatment of " marathon " formula causes greatly to patient
Pain, patient is difficult to pay expensive medical expense.Early recovery, being worked for patient early is very urgent and needs
, and hospital influences its economic benefit because medical cycle is long, bed turnover utilization rate is low.
In conclusion existing reduction unit is unfavorable for due to that can not adjust at any angle to the progress of spicule
The healing of patient leads to the problem that synthetism effect is poor or even disability rate is high.
Summary of the invention
The purpose of the present invention is to solve existing reduction units due to can not carry out any angle to spicule
