The knee joint approach intramedullary nail is provided with a nail shank which is provided with a through hole inside; the nail shank is provided with the far end and the near end; the near end of the nail shank is provided with three multi-plane interlocking holes which are distributed on three planes with different angles respectively and of which a crossing angle b is between 23 and 27 DEG; a tilt angle a between the near end of the nail shank and a central axis of the nail shank is between 9 and 12 DEG; the far end of the nail shank is provided with two groups of interlocking holes of which the crossing angle is 90 DEG; the interlocking holes are provided with oval pressurizing lockholes and circular lockholes; the near end of the nail shank is provided with an apparatus connection positioning rebate and an apparatus connecting screw hole.
Description
Technical field
Knee joint approach intramedullary nail of the present invention relates to is a kind of far away, interlocking intramedullary nail that near-end has the cross lock screw hole, is applicable to fracture of tibia and supracondylar fracture of the femur.
Background technology
The internal fixation implant is the standard femoral interlocking intramedullary nail during fracture of shaft of femur operation at present, adopts special-purpose operating theater instruments to carry out standard femur locking mode.During the fracture of tibia operation, adopt the tibia interlocking intramedullary nail, need to adopt another kind of special-purpose operating theater instruments to carry out the tibia locking, and need to open bigger otch on osteoderm, time ratio is long in the operation process, brings unnecessary misery to the patient.
Summary of the invention
The present invention seeks to provides a kind of knee joint approach intramedullary nail at above-mentioned weak point, the interlocking intramedullary nail that has the cross lock screw hole at far away, near-end, serve many purposes, be applicable to fracture of tibia and supracondylar fracture of the femur, be applicable to the shaft fracture of shin, the nearly section of femur section 1/3 extremely far away simultaneously, can utilize operating theater instruments, under less invasive techniques, finish resetting and implanting intramedullary pin of fracture.
Knee joint approach intramedullary nail takes following scheme to realize: knee joint approach intramedullary nail has in nail bar, the nail bar and does not have through hole, the nail bar is provided with near-end and far-end, the near-end of nail bar is provided with the hole of plane interlocking more than three, the hole of plane interlocking more than three is distributed in respectively on the plane of three different angles, interlocking hole, many planes angle of the crossing b each other is 23～27 °, is 9～12 ° at the proximal hub axis and the nail bar central axis angle of inclination a of nail bar.The far-end of nail bar is provided with two groups of intersection locking nail holes, two groups of intersection locking nail hole intersecting angles are 90 °, described intersection locking nail hole is provided with Long Circle pressurization locking nail hole and circular locking nail hole, and Long Circle pressurization locking nail hole is used for the power pressurization, and circular locking nail hole is used to be locked in skeleton.Be provided with apparatus connection locating notch at the near-end of following closely bar and be connected screw with apparatus.
When knee joint approach intramedullary nail uses, according to different patients use operating theater instruments connect locking bar with knee joint approach intramedullary nail such as patient's femur cannon born folding by in the bone marrow pears nest implanted femur on the femur marrow, by self-locking nail respectively with the near-end far-end locking on femur.As patient's fracture of tibia, implant in (knee joint approach) tibia pulp cavity by self-locking nail respectively near-end, far-end locking on neck by tibial knee.
Reasonable in design, the compact conformation of knee joint approach intramedullary nail, it is a kind of interlocking intramedullary nail that has the cross lock screw hole at far away, near-end, serve many purposes, be applicable to fracture of tibia and supracondylar fracture of the femur, be applicable to the shaft fracture of shin, the nearly section of femur section 1/3 extremely far away simultaneously, comprise transverse fracture, comminuted fracture, spiral fracture, oblique fracture and incomplete fracture.Can utilize operating theater instruments, under less invasive techniques, finish resetting and implanting intramedullary pin of fracture.Owing to only need in the operation on osteoderm, to open less otch, and can shorten operating time, reduce the patient suffering, the back rehabilitation of being convenient to perform the operation.
