Artificial hip joint device without handle

Abstract

A non-handle artificial hip joint unit is composed of a reinforcing plate for supporting femur and with more through holes for inserting the fixing parts through them to fix the reinforcing plate to the surface of femur, a reinforcing bone nail passing through the holes on reinforcing plate and inserted in fermur, a central bone nail screwed with said reinforcing bone nail, and a femur neck protector fixed to another end of said central bone nail. Its advantage is high strength and stability.

Description

technical field [0001] The invention relates to a device for jointing a femoral head damaged or broken due to disease, in particular to a handleless artificial hip joint device. Background technique [0002] For the joint method of the fractured femoral neck, the existing technology generally resets the fractured part, then covers it with a plate-shaped steel, and then drives it into the femur with two nails to fix it. In addition to the shortcomings of instability, the newly grown blood vessels and calluses cannot effectively cover the steel, so the plate steel cannot be fully integrated with the femur and protected, resulting in the fractured femur and The coated steel has limited strength and is easy to separate, which greatly reduces the practicality and increases the pain of patients. These shortcomings have long plagued medical professionals and patients. [0003] And another kind of femoral neck protector, though is to put a hollow cylindrical body on the femoral nec...

Problems solved by technology

[0002] For the joint method of the fractured femoral neck, the existing technology generally resets the fractured part, then covers it with a plate-shaped steel, and then drives it into the femur with two nails to fix it. In addition to the shortcomings of instability, the newly grown blood vessels and calluses cannot effectively cover the steel, so the plate steel cannot be fully integrated with the femur and protected, resulting in the fractured femur and The coated steel has limited strength and is easy to separate, which greatly reduces the practicality and increases the pain of patients. These shortcomings have long plagued medical professionals and patients.

[0003] And another kind of femoral neck protector, though is to put a hollow cylindrical body on the femoral neck to protect the femoral neck, but this hollow cylindrical body is only fixed on the femoral neck by means of a screw rod passing through the center, so that , for young people with better bone quality, the curative effect is quite good, but for the elderly and osteoporosis patients, the central screw will occasionally loosen

At the same time, this femoral neck protection device does not have any device to protect the femoral shaft. If the femur has poor bone quality or suffers from osteoporosis, the recovery speed will be slowed down.
