Abstract
The invention provides a double-hole suspension type artificial ligament. The double-hole suspension type artificial ligament comprises a thighbone tunnel free fiber portion, a thighbone tunnel knitting portion, a joint internal free fiber portion, a tibia tunnel knitting portion, a tibia tunnel free fiber portion and a draft line portion which are connected sequentially. The thighbone tunnel knitting portion is provided with a thighbone end single hole, and the tibia tunnel free fiber portion is provided with a tibia end single hole. The invention further provides a corresponding preparation method. The double-hole suspension type artificial ligament has the advantages that when a human anterior cruciate ligament is rebuilt by the artificial ligament, fixing of the artificial ligament is enhanced, contact area between the artificial ligament and a bone tunnel is enlarged, and accordingly, healing of the artificial ligament and the bone tunnel is facilitated. Further, the double-hole suspension type artificial ligament is simple in structure and convenient to use.
Description
Technical field
The present invention relates to the artificial ligament of implant into body, the artificial ligament that especially is connected with button plate particularly, relates to diplopore suspension artificial ligament and preparation method thereof.
Background technology
At present, clinical practice more and comparatively ripe artificial ligament in the whole world is the LARS artificial ligament of France, and this ligament is take high tenacity polyethylene terephthalate (PET) as raw material.Began to be applied to clinical in 1994, successfully used at home first in 2004, authenticate by European CE authentication and Chinese SFDA.The LARS artificial ligament is to be reeled to close up by polymer fiber net self to form, and is divided into both sides osseous tunnel section, middle joint fiber section and two ends draught line section.During LARS artificial ligament implantable bone tunnel, in femur and tibial tunnel, adopt respectively one piece of metallic screw extruding fixing.But, this fixed form has not only reduced the contact area of ligament and osseous tunnel, and because screw causes the ligament inner space to be reduced to the extruding of ligament, affects autologous tissue and grow into, osseous tunnel inner bolt at a specified future date easily occurs loosening, finally causes the failure of artificial ligament.
Summary of the invention
Be unfavorable for the defective that ligament and the healing of bone road and fixed form are not good for LARS artificial ligament in the prior art, the purpose of this invention is to provide a kind of diplopore suspension artificial ligament and preparation method thereof, can connect button plate according to artificial ligament provided by the invention and increase fixing firm degree, and more can increase the contact area of artificial ligament and osseous tunnel, thereby promote the healing of ligament and osseous tunnel
