Description
Technical field
The present invention relates to medical instruments fields, especially a kind of to establish the curved tunnel operation positioning device of kneecap.
Background technology
Kneecap is the maximum sub- bone of human body, is located in front of knee joint, has and protects kneed effect.The subsequent pass of kneecap
Nodal section is opposite with femoral bone pulley face.Quadriceps muscle of thigh is attached to kneecap upper limb, and part fascia in front of kneecap through extending for ligamentum patellae, only
In tibial tubercle.Kneecap plays a crucial role in human knee moves, for example, the intermediate knot as Quadriceps mechanism
Structure, the pulling force that quadriceps muscle of thigh generates is transmitted to kneecap tendon by it；Kneecap plays leverage when stretching knee, can effectively increase and stretch knee dress
Set the lever arm of force that axis point is bent and stretched for knee joint；By sliding of the kneecap on femoral bone pulley face, a strand four-head can also be cut down
Flesh is to the friction before distal part of femur.
Clinical manifestation：
Acute traumatic dislocation of the patella：- it is more common in teenager, there is knee trauma history.
- swelling is apparent, lateral margin tenderness in kneecap, limitation of activity.
- enuflex position：Kneecap shifts outward.
- upward dislocation：Kneecap is high-order.
Habitual dislocation of patella：
- microtrauma is repeatedly dislocated.
- knee is soft, pain, difficulty in walking, dare not be painstaking.
Sign shows：
Tenderness on the inside of kneecap, the experiment of kneecap fear are positive.
Nuclear-magnetism shows：
Band damage is supported in lateral margin bone bruise in kneecap, condylus lateralis femoris bone bruise, inside.
It is traditional all to use row twin tunnel method when dislocation of the patella carries out stabilizing procedure operative treatment, however traditional row
Twin tunnel method is to complete to turn back in kneecap offside, due to being operated on the outside of kneecap, is often made to kneecap lateral ligament
At different degrees of damage.And for row twin tunnel method, ligament needs to extend transversely through kneecap, and the use length of ligament can be very
Greatly.
Therefore this field, which is required to realize, establishes the curved tunnel of kneecap, by establishing curved tunnel, utilizes semitendinosus weight
Kneecap medial ligament is built, the matched medical appurtenance of this operation method of condylus medialis femoris is fixed on.
