Description
Technical field
The invention belongs to bone surgery apparatus field, it is related to a kind of hollow nail guide pin to aim at and fixing equipment, and in particular to
Torsion angle pinpoints the wrong guide pin sight and hollow nail designed away from method as reference system using vertical adjustable before with neck of femur
Fixed system.
Background technology
Three pieces of nail treatment fractures of neck of femur refer to through cortex of bone on the outside of near end of thighbone, by femoral neck bone broken line to neck of femur
Three pieces of hollow screw groups of interior screw-in, different stress are undertaken by rational deployment respectively, treat a kind of method of fracture of neck of femur.Three
Piece nail treatment fracture of neck of femur advantage be：Wound is small, and three pieces of thread steel nails are squeezed into neck of femur correct position；Wound is small,
Healing is fast, safe, severe complication seldom occurs；Curative effect affirms that postoperative a couple of days can discharge.
Three pieces of nail treatment fracture of neck of femur surgical effects are closely related with three pieces of nail location layouts, and not straightforward manipulation, is X
Operated under actinoscopy X.Fixation has turned into the medium-sized standard art formula with remote fracture of neck of femur of neck in three pieces of hollow nails, and its key is
Insert correct position and the ideal length of guide pin.Conventional guide pin inserts many range estimations by doctor and experience at present, lacks visitor
Being adjusted in measurement, the art of sight standard cannot also quantify, and there are the following problems：
1st, height relies on radioscopy；2nd, near end of thighbone is operated repeatedly causes Cranial defect, iatrogenic fracture, screw to hold
Power declines, loosens or move back nail；3rd, not only position and angle of the guide pin in neck of femur can not precisely determine, and be unable to reach reason
The guide pin length thought, guide pin and screw easily break through articular cartilage, damage pelvic cavity viscera and joint；4th, in the preoperative art of surgical doctor
Reusability C arm machine is needed to position, and surgical experience by clinician adjusts puncture needle and tries positioning on repeatedly.Young or face
When not abundant enough the doctor of bed experience operates, unavoidable increase perspective film making number of times, amount of radiation suffered by doctors and patients increases, and increases puncture time
Number, increases patient suffering.Even if the abundant doctor of clinical experience, be also used for multiple times in positioning unavoidably C arm machine film making positioning and
Repeatedly punctured using Kirschner wire.5th, in the natural calamity such as basic hospital and generation earthquake typhoon area, shortage C arm X-ray machines etc.
Equipment, the operation risk is very big.
At present, the dissection for only relying near end of thighbone, the femur neck hollow nail guide pin for being independent of radioscopy in art are lacked
Aim at fixed system.Therefore, it is badly in need of simple clinical one kind, practicality, reduces operating difficulty, improve procedure efficiency, increases hand
The femur neck hollow nail guide pin of art security is aimed at and hollow nail fixed system.
The content of the invention
It is an object of the invention to provide a kind of simple structure, esy to use, safe and reliable, accurate, raising procedure efficiency, increase
Plus torsion angle reference system-fixed point is wrong away from guide pin aiming hollow nail fixed system before the neck of femur of operation safety.The present invention is referred to
Neck of femur before the torsion angle dihedral angle that to be neck of femur longitudinal central axis face formed near end of thighbone coronal-plane, the angle is by neck of femur
Reverse to be formed forwards along its longitudinal central axis line；Different from the top rake of neck of femur, (i.e. neck of femur longitudinal central axis line is near with femur
The end line face angle that is formed of coronal-plane, the angle be neck of femur near end of thighbone longitudinal central axis line as axle, forward rotation formed).
To achieve these goals, the technical scheme is that：Torsion angle reference system-vertically adjustable before neck of femur is provided
Formula fixed point is wrong to be aimed at and hollow nail fixed system away from guide pin, wherein, including neck of femur near point positioner, neck of femur far point positioning
