Abstract
The utility model provides an integrated annular suspended artificial ligament which comprises a ligament woven portion (1) and a traction line (2). The ligament woven portion (1) is of a closed loop structure, and the traction line (2) is connected with the ligament woven portion (1). The integrated annular suspended artificial ligament has the advantages that before the artificial ligament is used for rebuilding human anterior cruciate ligament, the artificial ligament is fixed to enlarge the contact area between the artificial ligament and a bone tunnel to improve union between the artificial ligament and the bone tunnel; and the integrated annular suspended artificial ligament is simple in structure and convenient to use.
Description
Technical field
This utility model relates to the artificial ligament of implant into body, and the artificial ligament that especially is connected with button plate particularly, relates to integrated ring-type suspention artificial ligament.
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 occurs loosening easily, finally causes the failure of artificial ligament.
The utility model content
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 utility model provides a kind of integrated ring-type suspention artificial ligament and preparation method thereof.The artificial ligament that provides according to this utility model can connect the fixing firm degree of button plate increase, and more can increase the contact area of artificial ligament and osseous tunnel, thereby promotes the healing of ligament and osseous tunnel.
According to an aspect of the present utility model, a kind of integrated ring-type suspention artificial ligament is provided, comprise ligament knit unit 1 and draught line 2, wherein, described ligament knit unit 1 is closed loop configuration, described draught line 2 is connected in described ligament knit unit 1.
Preferably, the relative two ends of described ligament knit unit are the U font structure, and the mid portion between the described relative two ends closes up mutually.
Preferably, it is about the line of the mid point at described two ends axisymmetricly.
The beneficial effect of this utility model patent is, can when using artificial ligament to rebuild people's anterior cruciate ligament, strengthen the contact area of fixing and increase artificial ligament and the osseous tunnel of artificial ligament, thereby promote the healing in artificial ligament and bone road, and simple in structure, easy to use.In the ACL reconstruction operations, the band button plate of selecting as required corresponding length is connected with ring loop between two femur tunnel sections of artificial ligament.When this artificial ligament implantable bone tunnel, femur tunnel end employing button plate is connected with artificial ligament to suspend in midair and fixes.Because of to a greater degree contact area increase in femur and tibial tunnel section ligament and the osseous tunnel, and ligament inner space larger (without the screw extruding), can reach and strengthen fixing purpose.
Description of drawings
By reading the detailed description of non-limiting example being done with reference to the following drawings, it is more obvious that other features, objects and advantages of the present utility model will become:
Fig. 1 illustrates the structural representation according to integrated ring-type suspention artificial ligament of the present utility model.
The specific embodiment
Fig. 1 illustrates the structural representation according to integrated ring-type suspention artificial ligament of the present utility model.Particularly, in the present embodiment, suspend artificial ligament in midair according to the integrated ring-type that this utility model provides, comprise ligament knit unit 1 and draught line 2, wherein, described ligament knit unit 1 is closed loop configuration, and described draught line 2 is connected in described ligament knit unit 1.Described ligament knit unit 1 can directly be connected with band button plate (Endobutton), and behind the implant into body femur tunnel, the Endobutton button plate that connects can block and is pressed in outside the femur tunnel face, and ligament is played the suspention fixation.
Preferably, the relative two ends of described ligament knit unit are the U font structure, and the mid portion between the described relative two ends closes up mutually.Integrated ring-type suspention artificial ligament about the line of the mid point at described two ends axisymmetricly.
In an embodiment of the present utility model, the preparation method of described integrated ring-type suspention artificial ligament comprises the steps:
Steps A: a rectangle pet fiber net is carried out self being wound into cylinder along major axis;
Step B: should sew up by cylindrical two free ends, make cylinder form a closed hoop as described ligament knit unit 1.
Preferably, also comprise the steps:
Step C: described draught line 2 is installed at an end of described ligament knit unit 1.
In another embodiment of the present utility model, the preparation method of described integrated ring-type suspention artificial ligament comprises the steps:
Steps A: prepare to throw the net the different rectangle pet fiber net of lattice density more, the pet fiber net of mesh-density maximum is carried out self being wound into cylinder as core along major axis, remaining described pet fiber net carries out self being wound into cylinder along major axis successively and forms the composite cylindrical body to wrap layer by layer described core according to mesh-density is descending;
Step B: two free ends of this composite cylindrical body are sewed up, made the composite cylindrical body form a closed hoop as described ligament knit unit 1.
Preferably, also comprise the steps:
Step C: described draught line 2 is installed at an end of described ligament knit unit 1.
More than specific embodiment of the utility model is described.It will be appreciated that this utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or modification within the scope of the claims, and this does not affect flesh and blood of the present utility model.
Claims (3)
1. an integrated ring-type suspention artificial ligament is characterized in that comprise ligament knit unit (1) and draught line (2), wherein, described ligament knit unit (1) is closed loop configuration, and described draught line (2) is connected in described ligament knit unit (1).
2. integrated ring-type suspention artificial ligament according to claim 1 is characterized in that the relative two ends of described ligament knit unit are the U font structure, and the mid portion between the described relative two ends closes up mutually.
