Description
Technical field
The utility model relates to the field of medical instrument technology, in particular to a kind of fixation button for ligament reconstructive.
Background technique
Cruciate ligaments of knee joint is also known as ligamentum cruciatum, is located in femur between ectocondyle, front and back two crosses one another.Preceding friendship
Fork ligament arises from the outer rear portion of fossa intercondylaris femoris, forward, it is interior, under terminate on front side of shin bone spine.Posterior cruciate ligament of knee arises from fossa intercondylaris femoris
Interior front, backward, outside, under terminate on rear side of shin bone spine.Anterior cruciate ligament prevents shin bone from shifting forward；Posterior cruciate ligament of knee then prevents shin
Bone rearward displacement.Cross ligament damage is mostly as caused by hyperextension violence or outreach outward turning shank.Its tear can occur starting point,
Body portion or stop.Often merge the avulsion fracture of shin bone spine.Posterior cruciate ligament injuries are mostly since proximal ends of tibia is directly hit in violence
Caused by front.Tearing can occur at femur or shin bone attachment.When such as damaging, for knee joint position in semiflexion, combinable front fork is tough
Band damage.
Inventor has found in the process of implementing the utility model, after ligamentaum cruciatum damages, will lead to joint
Degeneration that is unstable and causing its hetero-organization.Since the self-repairing capability of ligament is very poor, the ligament after damage must pass through
Operating substitution is to restore its function.Although existing in the prior art by way of screw or the fixed ligament of suspension method,
It is limited to the limitation of fixed device, bungee jumping effect and rain brush effect caused by being not fixed firmly as transplanting tendon often occurs,
These can all influence subsequent ligament reconstructive effect.
