Description
Technical field
The present invention relates to femoral head replacement fields, and in particular to a kind of percutaneous artificial femoral head replacement's device.
Background technique
At present for femoral head, neck of femur, greater trochanter fracture and caput femoris necrosis, it is on the verge of to collapse or collapse-deformation person
Feasible artificial femoral head replacement.Current artificial femoral head replacement surgery need to do posteriolateral incision, after appearing capsula articularis coxae, along hip
Mortar edge lines T shape is cut, and joint capsule is cut edge and is sling with cordonnet, and operative incision is big, and intraoperative hemorrhage is more, after cutting
Outside muscle group be easy to cause dislocation, increases operation risk.In view of this, how to reduce hand in artificial femoral head replacement surgery
Art notch reduces the complication such as intraoperative hemorrhage and muscle group dislocation, reduces operation risk, significant.
Summary of the invention
The purpose of the invention is to provide a kind of operative incision that can be effectively reduced in artificial femoral head replacement surgery, subtract
The complication such as few intraoperative hemorrhage and muscle group dislocation, to reduce percutaneous artificial femoral head replacement's device of operation risk.
The technical scheme is that
A kind of percutaneous artificial femoral head replacement's device, comprising:
Kirschner wire, for percutaneously squeezing into femoral head, to play the guiding role when taking out the femoral head of truncation, or for squeezing into stock
The greater trochanter of bone, to form pin hole on the greater trochanter of femur, or for percutaneously squeezing into neck of femur；
Bone drill is taken, takes bone drill for taking out the femoral head of truncation, interior be equipped with of bone drill is taken to take bone drill guide through hole, the Kirschner wire energy
Enough insertions take in bone drill guide through hole, so as to which bone drill is taken to move along Kirschner wire and rotate around Kirschner wire；
Femur openings lead device, femur openings lead device include guide through hole in guide post and the column being arranged in guide post, institute
It states guide through hole in column to be used for when Kirschner wire percutaneously squeezes into the greater trochanter of femur, play the guiding role to Kirschner wire；
Long guide pin, for being inserted into femur, in reaming on femur, to play the guiding role to reamer, or in marrow in reamer
When chamber file expands femoral bone cavitas medullaris, it play the guiding role to Myelocavity file；
Reamer, reamer are equipped with reamer for expanding the pin hole that Kirschner wire is formed on the greater trochanter of femur, reamer
Guide through hole, the long guide pin is inserted into reamer guide through hole, so that reamer is moved or rotated along long guide pin；
