Abstract
The invention provides a sectional-type annular suspended artificial ligament which comprises a femoral end ring loop (1), a first femoral tunnel weaving part (2), a first intra-articular free fiber part (3), a first tibial tunnel weaving part (4), a tibial end ring loop (5), a second tibial tunnel weaving part (6), a second intra-articular free fiber part (7) and a second femoral tunnel weaving part (8) that are connected end to end sequentially to form a ring. The invention further provides a preparation method of the sectional-type annular suspended artificial ligament. The sectional-type annular suspended artificial ligament has the benefits that when the artificial ligament is used to reconstruct a human anterior cruciate ligament, the fixation of the artificial ligament is intensified, and a contact area between the artificial ligament and a bone tunnel is increased, thereby promoting the healing of the artificial ligament and the bone tunnel; and the 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 stagewise ring-type suspention 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.
