Description
Technical field
The present invention relates to reduction of the fracture device technical field, specially a kind of composite bone fracture restorer.
Background technology
In the prior art, resetted for fracture fixation and be generally divided into two classes, a class is interior fixation, it is another kind of to be outer solid
It is fixed, steel plate and intramedullary needle etc. are inside fixed with, Plate internal fixiation is larger to soft tissue injury, it is necessary to two operations, the pain of patient
Greatly, intramedullary needle fixes destruction pulp cavity inner membrance blood fortune, and anti-rotation, bend resistance power are poor, be unfavorable for reduction of the fracture healing, folder is fixed with outside
Plate is fixed, plaster fixing and outer fixation etc. of threading a needle, and Boards wall is not firm enough, ties up cumbersome, not manageability, influences soft group
Blood fortune is knitted, caused complication is more, and plaster fixing is not firm, and influence closes on joint motion, the outer single arm type that is fixed with of threading a needle is consolidated
Fixed and ring type fixation etc., the anti-axial force of single arm type fixation is poor, though ring type fixes fixation, volume is larger, is difficult behaviour
Make, it is heavy, it is unfavorable for patient and rests, such as Patent No. 87210403.6, it is mainly by holding pin adjustment frame, needle stand, pin folder, angle
The composition such as adjustable plate and adjustment arm is spent, the fixing reductor substantially overcomes single arm type fixing reductor and ring type fixed reset
The shortcoming of device, but still there are the following problems, complicated, requirement on machining accuracy is high, thus cost of manufacture is high；It can be used only in length
On bone, it is impossible to which, according to the random dismountable of the state of an illness, the use of privileged sites is subject to certain restrictions；It is cumbersome, it is difficult to control,
