Description
Technical field
The invention belongs to the field of medical instrument technology, are related to a kind of interlocking stock for preventing hip-joint replacement prosthesis from sinking
Bone handle prosthetic appliance.
Background technique
Artificial bones of the body joint replacement is the serious bones of the body arthropathy of current clinical treatment and femoral neck fracture in elders and portion
Divide the most effectual way of intertrochanter fracture of femur, and with aging of population, bone and joint diseases are increasing, and the whole world is often only
Bones of the body joint replacement is just about 1,000,000, it has rebuild the function in lesion joint, significantly improves the ability to work and life of patient
Bioplasm amount, the treatment means as a kind of maturation are at home and abroad widely applied.
However, type femoral bone end prosthesis surrounding fracture is all that mono cortex screw is fixed, such fixed form is easy
Cause operation wound larger, the length that screw is capable of fixing is too short and easy loosening, it is fixed unstable the problems such as, to cause under prosthese
It is heavy, therefore, it is badly in need of a kind of can be reduced operation wound and fixed more steady type femoral bone end prosthesis fixing means.
Summary of the invention
The object of the present invention is to provide a kind of for preventing the interlocking type femoral bone end prosthesis device of hip-joint replacement prosthesis sinking,
Solve the problems, such as that existing type femoral bone end prosthesis fixed form operation wound is big and prosthese is easy to sink to loosening.
The technical scheme adopted by the invention is that the interlocking type femoral bone end prosthesis dress for preventing hip-joint replacement prosthesis from sinking
It sets, including femur shank body, femur shank body upper end is fixed with handle neck, and handle neck upper end is provided with button, is arranged on the external wall of femoral stem
There are several fins, femur shank body side is additionally provided with the fixed frame for resected femur shank body.
Femur shank body upper end is additionally provided with fixing groove.
Several screw holes for running through femur shank body are horizontally arranged in femur shank body.
Fixed frame includes fixed link, connecting rod and sighting bar, the both ends of connecting rod respectively with fixed link and sighting bar
One end connects and composes L shape structure, and the other end of fixed link is embedded in fixing groove.
It is provided with several sight holes on sighting bar, a sleeve is provided in each sight hole, screw is worn by sleeve
Enter in screw hole.
The number of screw hole and the number of sight hole are consistent.
The invention has the advantages that a kind of interlocking type femoral bone end prosthesis dress for preventing hip-joint replacement prosthesis from sinking
It sets, fixed frame is set, sight hole is set on fixed frame, sleeve is set in sight hole, it is convenient to be squeezed into screw by sleeve
Femur shank body is fixed in femur shank body, is fixedly connected with femur shank body with fixed frame, hip joint is can effectively prevent and sets
Prosthese sinking is changed, several fins is provided on the external wall of femoral stem, the combination of femur shank body and knee ossis can be made tighter
It is close, prevent femur shank body from loosening, which not only reduces reduction operation wound and fixation is more steady.
