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.

Ring F is connect with the adjustable wire loop B closed loop；Second fixed button A2, the described second fixed button A2 are equipped with and described the
The matched one or more through-holes of the shape of two fixed button A2, it is solid that the fixed wire loop F passes through described second in a closed loop manner
Determine one or more through-holes of button.
It optionally, further include the draught line C with the first color pattern on the reconstructing system, the draught line C has
For the first end and second end by the through-hole, area of section the cutting less than the adjustable wire loop B of the draught line C
Face area.
Optionally, the reconstructing system further includes turning over the line D that stumbles with the second color pattern, the second color pattern with
The first color pattern is different, and the line D that stumbles that turns over has for the third end and the 4th end by the through-hole, and described turn over is stumbled
The area of section of line D is less than the area of section of the adjustable wire loop B.By by draught line C and turning over the line D that stumbles and being set as different
Pattern to draught line C and can turn over the line D that stumbles and quickly identified when in use convenient for user, convenient to use.By by draught line
It C and turns over the line D that stumbles and is set as lesser area of section, can reduce draught line C under the premise of guaranteeing to exert oneself intensity in this way and turn over
It stumbles the fineness of line D, while draught line C and turning over can be reduced accordingly and stumbled the pore size of through-hole that line D passes through, save
Space.
Specifically, adjustable wire loop B can be made of litzendraht wire, pass through the leading in the fixed button by the litzendraht wire
The adjustable wire loop is knitted to form in hole.
Alternatively situation, the adjustable wire loop B can also be made of fiber line, by the way that the fiber line exists
The adjustable wire loop is wound in the through-hole of the fixed button.
During actual use, user can be adjusted by adjusting adjusting line B2 and B3 in adjustable wire loop
The length for saving the pars contractilis for adjusting line composition of the side B1 applies pressure to winding wire loop E and fixed wire loop F by pars contractilis, into
And the pressure between the first fixed fixed button A2 of button A1 and second is made to be in adjustable state.Pass through above-mentioned dynamic pressurized
Ligament reconstructive system flexibly and effectively can be bound or be fixed to ligament.
