Technical field
The utility model is related to fracture site resetting tool technical fields, are specifically related to a kind of shaft fracture closed reduction
Tool.
Background technology
In Orthopedic Clinical treatment, fracture of femoral shaft is relatively conventional, predominantly traffic accident, the violences such as fall, injure by a crashing object and hit institute
It causes.At present to the treatment of fracture of femoral shaft based on performing the operation, substantially divides in marrow and be fixed outside marrow, is i.e. open reduction and closure
Two kinds of redution-in-fixed, at present to be fixed as standard in closed reduction intramedullary nail.It finds, is closed by a large amount of clinical test
There are following some difficulties for reduction fixation therapeutic scheme:
First, because leg muscle is abundant, fracture site displacement is apparent, and swelling is apparent in addition, and gimmick and traction can not be to stocks
The shaft fracture broken ends of fractured bone carries out active homing, is difficult to maintain to reset by patient and assistant's hand strength, and operating space is limited, from
And influence operation;
Secondly, fracture of femoral shaft generally will appear cripetura and lateral displacement, we will not only solve the shifting of sagittal plain in art
Position will also correct the displacement of Coronal, depend merely on manpower and be difficult to reset and maintain;
Again:Fracture of femoral shaft amount of bleeding is big, and 3-7 days generally after wound are to choose date for operation opportunity, if any thrombosis, hand
Art period can be postponed, therefore organization of hematoma makes reset more difficult, and also needing to Limited exposure when necessary could reset.
In conclusion it is fixed in clinically widely used fracture of femoral shaft closed reduction intramedullary nail at present, it is multiple in art
Position technology is more important, and manipulative reduction has clearly disadvantageous place, extends operating time and a large amount of muscle power for consuming patient,
Operation risk is increased, or even has the possibility for leading to operative failure, therefore to current fracture of femoral shaft repositioning method and instrument
It is very necessary to be improved.
