Description
Technical field
The present invention relates to orthopedic medical device field, more particularly to it is a kind of solid with marrow cavity of femur form matches near-end
Determine intramedullary pin.
Background technology
Femur is the maximum elongated tubular stock of human body, in human body lower limbs thigh, carries all of human body top half
Weight, near-end participates in composition hip joint connection basin bone, and distal end participates in composition knee joint connection calf shank.But Diaphysial disease,
Fracture phenomenon occurs often.
Locking steel plate inner fixation treatment of femoral shaft fractures and intramedullary nail treatment fracture of shaft of femur are that current two kind mainly control
Treatment mode.It is that femur external edge surface is fixed to fracture area using fixing steel plate that locking steel plate is fixed, to fracture into
Row treatment.Intramedullary nail treatment, is to insert to position femur in femoral bone cavitas medullaris using steel nail, and Fracture of femur is treated.
For the fracture of the special tibia sites that cannot apply intramedullary pin, Interal fixation still can not replace, but intramedullary pin is also increasingly
It is widely used in the treatment of fracture of tibia.
However, its primary stability and biomechanicss fixed effect thereafter are undesirable after intramedullary pin implantation at present, Jing is normal
Generation such as loosens, sinks, rotates and subsides the phenomenon.Related mechanics study shows, is implanted in the form of intramedullary pin and femoral bone cavitas medullaris
Form be mutually matched, the transmission that can make load forces more conforms to psychological need.Avoid because interface produces between implant and bone
Tangential motion and cause the loosening of implant, reduce stress shielding the problems such as.
During clinical operation, doctor need constantly to contrast implant, moulding (bending cutting etc.) not only handss
The art time is long, and effect is poor, and also add the pain degree of patient.In addition femoral bone cavitas medullaris are an irregular conical pipes
Chamber, into irregular curve form, from the close-by examples to those far off, the major axis of tomography is into outward turning trend, this distortion near end of thighbone for femoral bone cavitas medullaris
The presence of angle, certainly will cause expanding appearance rotation in the middle of marrow and implant security protection process, cause the change of top rake, in addition existing
Vertical state is approximately some intramedullary pins more, causing implant and femoral bone cavitas medullaris to match completely more difficult.
The intramedullary pin that Current Domestic is used mostly is import or copies foreign country, but the parameter of Chinese and western femur measurement
It is different, so using this imitated external intramedullary pin matched well cannot be carried out with state's human femur.Now the country has
A little medical apparatus and instruments producers design intramedullary pin according to the femur parameter and standard of compatriots, and arrange different size.But due between patient
Individual variation, the morphological requirements of intramedullary pin still cannot meet the demand between Different Individual.
To sum up, the fixation of existing intramedullary pin mainly has problems with：
1. the main nail fracture of intramedullary pin, discontinuity equalization；
2. Intramedullary nailing is unstable, and the implantation later stage can produce loosening；
3. the form of intramedullary pin cannot carry out Perfect Matchings with the geometric shape of femoral bone cavitas medullaris, easily occur in implantation process
Distortion, it is difficult to meet good biomechanicss requirement.
The content of the invention
A kind of near-end fixation intramedullary pin matched with marrow cavity of femur form is embodiments provided, is solved existing
There is the intramedullary pin form in technology to carry out Perfect Matchings with the geometric shape of femoral bone cavitas medullaris, easily occur turning round in implantation process
It is bent, it is difficult to meet good biomechanicss requirement, and unstable easy generation of fixation loosen and power is unbalanced easily causes main nail
The technical problem of fracture.
