Abstract
The invention provides a kind of femoral prosthesis, including：Femoral stem main body；Prolonging handle；Transition member, the first end of transition member are connected with femoral stem main body, and the second end of transition member is connected with prolonging handle.It is more difficult that the femoral prosthesis of the present invention solves the problems, such as that femoral prosthesis of the prior art takes out.
Description
Technical field
The present invention relates to artificial prosthesis field, in particular to a kind of femoral prosthesis.
Background technology
The type femoral bone end prosthesis with anterior arch is currently there are, but it is left and right side prosthesis that these, which have the prosthese of anterior arch,
Separate, i.e., left side hip replacement and the anterior arch prosthese of right hips displacement are separated, it is necessary to according to circumstances select different
Anterior arch prosthese.The stock of product when can thus increase operation, also easily the surgeon to lack experience is caused to cause mistake
Operation.
Artificial hip joint replacing is to treat one of hip joint disease effective means the most universal, Periprosthetic fracture at present
It is the serious complication of total hip arthroplasty latter.In recent years, Periprosthetic fracture incidence has the trend increased, leads
The reason for causing postoperative Periprosthetic fracture has a lot, including the dissolving of osteoporosis, bone, prosthetic loosening etc..There are some after fracturing
Need to overhaul after prosthese is taken out, in fact, more than prosthese need to be taken out and be overhauled by Periprosthetic fracture, prosthese such as occur not
Situations such as stable, prosthese hits, it is also desirable to take out prosthese.
It is bone cement prosthese for Primary replacement prosthese, the taking-up of its type femoral bone end prosthesis is relative to be easier to, main difficulty
Topic is to take out bone cement in itself.It is uncemented prostheses for Primary replacement prosthese, the taking-up of femoral stem is often more tired
Difficulty, because there is good Bone Ingrowth between type femoral bone end prosthesis and bone tissue, taking out such prosthese needs first to separate metal with instrument
With the interface of bone, and dynamics is needed to be grasped, because beating for Violent easily causes bone to perforate, to operation technical requirements pole
Height, and perform the operation and expend time length, the risk of increase patient's infection.
