Description
Technical field
The present invention relates to medical instruments fields, and in particular to a kind of positioning auxiliary device for fracture of neck of femur.
Background technology
Fracture of neck of femur is adult's multiple fracture, in recent years, as average human life increases, fracture of neck of femur incidence
In apparent ascendant trend, such fracture has higher disability rate and the death rate, patient once to fracture, if without operative treatment,
Long-term bed is then needed, related complication occurrence probability is caused to greatly increase, such as hypostatic pneumonia, bedsore, deep vein thrombosis, muscle
Atrophy, osteoporosis, urinary system infection contamination, osteoporosis, and caput femoris necrosis probability can be increased.
Internal fixation treatment is carried out to fracture of neck of femur, its purpose is that carrying out anatomical reduction to fracture as far as possible, reduces femur
The downright bad occurrence probability of head, makes fracture obtain strong fixation, is conducive to patient's early ambulation, reduce complication rate.
The selection of fracture of neck of femur internal fixation method, for the patient less than 60 years old, be typically chosen three pieces of pulling force it is hollow plus
Screw is pressed to fix fracture, three pieces of screws are placed in neck of femur in three-dimensional perspective.The internal fixation method can provide neck of femur for patient and be cured
Chance is closed, once caput femoris necrosis occurs later, considers further that row prosthetic replacement treats, corrective surgery expense can be reduced in this way
With as far as possible using the joint of patient oneself.It is auxiliary usually using the C-arm X-ray machine with radiophotography function in surgical procedure
It helps, is resetted patient femur's fracture of cervical vertebra using bone traction frame, combine sighting device later, hollow screw guide pin is placed in stock
Bone neck precalculated position reuses hollow boring bit and drills along guide pin, is screwed into hollow screw.
Under current medical conditions, doctor is usually led by rule of thumb when guide pin is placed in neck of femur precalculated position
Needle is placed in, and tends not to that guide pin is disposably placed in precalculated position, need to be injected, be extracted repeatedly, and operation is repeated, until position is full
Meaning, this serial procedures increases operating time, operation wound, amount of bleeding, and Reusability C-arm X-ray machine is needed to be had an X-rayed
Operation makes patient and medical worker absorb excessive X-ray, high risks patient and medical worker's health.
