Abstract

The invention provides an integral annular suspension artificial ligament, which comprises a ligament woven part (1) and a traction line (2), wherein the ligament woven part (1) has an enclosed annular structure; and the traction line (2) is connected to the ligament woven part (1). The invention further provides a corresponding preparation method. The integral annular suspension artificial ligament has the beneficial effects that: fixation of the artificial ligament can be enhanced, and the contact area between the artificial ligament and a bone tunnel can be increased during reconstruction of a human anterior cruciate ligament by using the artificial ligament, so that healing of the artificial ligament and the bone tunnel is facilitated; and moreover, the integral annular suspension artificial ligament is simple in structure, and is convenient to use.

Description

Integral annular suspension artificial ligament

Technical field

The present invention relates to the artificial ligament of implant into body, the artificial ligament be especially connected with button plate, particularly, relate to integral annular suspension artificial ligament and preparation method thereof.

Background technology

At present, the more and comparatively ripe artificial ligament of world clinical application is the LARS artificial ligament of France, this ligament with high tenacity polyethylene terephthalate (PET) for raw material.Within 1994, start to be applied to clinical, within 2004, successfully use at home first, by European CE certification and Chinese SFDA certification.LARS artificial ligament is closed up by polymer fiber net wound on itself to be formed, and is divided into osseous tunnel portion, both sides, middle joint fiber portion and draught line portion, two ends.During LARS artificial ligament implantable bone tunnel, in femur and tibial tunnel, adopt one piece of metallic screw extruding fixing respectively.But, this fixed form not only reduces the contact area of ligament and osseous tunnel, and causes ligament inner space to be reduced because of the extruding of screw to ligament, affects autologous tissue and grows into, osseous tunnel inner bolt at a specified future date easily loosens, and finally causes the failure of artificial ligament.

Summary of the invention

Be unfavorable for ligament and the defect that bone road heals and fixed form is not good for LARS artificial ligament in prior art, the object of this invention is to provide a kind of integral annular suspension artificial ligament and preparation method thereof.Button plate can be connected according to artificial ligament provided by the invention and increase fixing firmness, and more can increase the contact area of artificial ligament and osseous tunnel, thus promote the healing of ligament and osseous tunnel.

According to an aspect of the present invention, provide a kind of integral annular suspension artificial ligament, 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 to described ligament knit unit 1.

Preferably, the mid portion that the relative two ends of described ligament establishment department are between U-shaped structure, described relative two ends closes up mutually.

Preferably, its line about the mid point at described two ends axisymmetricly.

According to another aspect of the present invention, a kind of preparation method of integral annular suspension artificial ligament is provided, comprises the steps:

Steps A: a rectangle pet fiber net is carried out wound on itself along major axis and becomes cylinder;

Step B: sewed up by these cylindrical two free ends, makes cylinder form a closed hoop as described ligament knit unit 1.

Preferably, also comprise the steps:

Step C: install described draught line 2 in one end of described ligament knit unit 1.

According to a further aspect of the invention, a kind of preparation method of integral annular suspension artificial ligament is provided, comprises the steps:

Steps A: prepare the rectangle pet fiber net that multiple mesh-densities are different, pet fiber net maximum for mesh-density is carried out wound on itself along major axis becomes cylinder as core, pet fiber net described in remaining carries out wound on itself along major axis successively become cylinder to form composite cylindrical body to wrap described core layer by layer according to mesh-density is descending;

Step B: sewed up by two of this composite cylindrical body free ends, makes composite cylindrical body form a closed hoop as described ligament knit unit 1.

Preferably, also comprise the steps:

Step C: install described draught line 2 in one end of described ligament knit unit 1.

The beneficial effect of patent of the present invention is, can, when using artificial ligament reconstructive people anterior cruciate ligament, strengthen the contact area of the fixing of artificial ligament and increase artificial ligament and osseous tunnel, thus promote the healing in artificial ligament and bone road, and structure be simple, easy to use.In ACL reconstruction operations, the ring loop between two femoral bone tunnel portions of the band button plate of corresponding length and artificial ligament is selected to be connected as required.When this artificial ligament implantable bone tunnel, femoral bone tunnel end adopts button plate to be connected with artificial ligament Suspending fixation.Because of in femur and tibial tunnel portion ligament and osseous tunnel to a greater degree contact area increase, and ligament inner space larger (without screw extruding), can reach the object of strengthening fixing.

Accompanying drawing explanation

By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present invention will become more obvious:

Fig. 1 illustrates the structural representation according to integral annular suspension artificial ligament of the present invention.

Detailed description of the invention

Fig. 1 illustrates the structural representation according to integral annular suspension artificial ligament of the present invention.Particularly, in the present embodiment, according to integral annular suspension artificial ligament provided by the invention, 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 to described ligament knit unit 1.Described ligament knit unit 1 can directly be connected with band button plate (Endobutton), and after implant into body femoral bone tunnel, the Endobutton button plate connected can block and is pressed in outside femoral bone tunnel mouth, plays Suspending fixation effect to ligament.

Preferably, the mid portion that the relative two ends of described ligament establishment department are between U-shaped structure, described relative two ends closes up mutually.Integral annular suspension artificial ligament about the mid point at described two ends line axisymmetricly.

The present invention also provides the preparation method of integral annular suspension artificial ligament.

In one embodiment of the invention, the preparation method of described integral annular suspension artificial ligament, comprises the steps:

Steps A: a rectangle pet fiber net is carried out wound on itself along major axis and becomes cylinder;

Step B: sewed up by these cylindrical two free ends, makes cylinder form a closed hoop as described ligament knit unit 1.

Preferably, also comprise the steps:

Step C: install described draught line 2 in one end of described ligament knit unit 1.

In another embodiment of the present invention, the preparation method of described integral annular suspension artificial ligament, comprises the steps:

Steps A: prepare the rectangle pet fiber net that multiple mesh-densities are different, pet fiber net maximum for mesh-density is carried out wound on itself along major axis becomes cylinder as core, pet fiber net described in remaining carries out wound on itself along major axis successively become cylinder to form composite cylindrical body to wrap described core layer by layer according to mesh-density is descending;
