Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically the structure of artificial ligaments, and more particularly to an artificial ligament made of gauze tissue. Background Technology

[0002] Artificial ligaments are medical devices used to replace or repair damaged ligaments, and are widely used in sports medicine and orthopedics. Currently, the main structures of artificial ligaments include the following:

[0003] (1) Single bundle structure: The single bundle structure is the simplest artificial ligament design, usually composed of a single high-strength fiber or fiber bundle. The advantages of this structure are that it is simple to manufacture and has a low cost, but its mechanical properties are relatively simple and it is difficult to simulate the complex mechanical behavior of natural ligaments.

[0004] (2) Multi-bundle structure: The multi-bundle structure consists of multiple fibers or fiber bundles arranged in parallel, which can provide higher strength and better mechanical properties. The design of the multi-bundle structure can more closely resemble the mechanical properties of natural ligaments, but there are certain complexities in terms of weaving and fixation.

[0005] (3) Woven Structure: A woven structure is formed by interlacing multiple fibers or fiber bundles in a specific weaving method to create a three-dimensional mesh structure. This structure can better simulate the anisotropic mechanical properties of natural ligaments, providing better biocompatibility and mechanical properties. During weaving, warp yarns, weft yarns, and skein yarns can be used to form a porous structure. For example, CN218356467U discloses a novel artificial ligament, including an artificial ligament body. The artificial ligament body includes a free portion, a first bone marrow tract woven portion, a first traction portion, a first fixation portion, a second bone marrow tract woven portion, a second traction portion, and a second fixation portion. The first and second bone marrow tract woven portions are connected to both ends of the free portion. The other end of the first bone marrow tract woven portion is connected to the first traction portion, and the other end of the first traction portion is connected to the first fixation portion. A traction wire is fixedly connected to the first fixation portion. The other end of the second bone marrow tract woven portion is connected to the second traction portion, and the other end of the second traction portion is fixedly connected to the second fixation portion. A bone screw is fixedly connected to the other end of the second fixation portion. The weaving method of this scheme is relatively complex and takes a long time to manufacture.

[0006] Although artificial ligaments have achieved some success in clinical practice, there are still some problems with their structural design, mainly including mismatch in mechanical properties. Existing artificial ligament structures are often unable to adapt to complex stress environments in terms of mechanical properties, and their tensile strength decreases during long-term use, leading to fatigue fractures or loosening.

[0007] Meanwhile, there is a biocompatibility problem, the artificial ligament may cause an immune response or an inflammatory response after being implanted in the body, and the thickness of the artificial ligament is difficult to reduce under the premise of meeting a certain tensile force, and the human body has a foreign body sensation. Practical new type content

The two ends of the main body section are connected with the first traction section and the second traction section respectively, which are composed of uninterwoven ground warp and / or twisted warp. The integrated artificial ligament structure is stable, and the traditional artificial ligament mesh sewing forming process is omitted, the artificial ligament manufacturing method is simplified, the manufacturing time is shortened, and the mechanical properties and biocompatibility are improved.

[0017] Further, the length of the main body section is 300-500 mm, the circumference is 5-15 mm, and the thickness is 1.5-2.0 mm.

[0018] Further, the density of the weft yarns in the main body section is not the same, the main body section comprises a central joint cavity section and first and second bone marrow channel sections at two ends of the joint cavity section, and the density of the weft yarns in the joint cavity section is lower than that of the weft yarns in the first and second bone marrow channel sections.

The artificial ligament of the heddle organization of the utility model can also realize the increase of the density of the yarn at both ends, the reduction of the pore density and the increase of the bonding force with the anchor nail through the adjustment of the weft density or the composition of different shuttle loom structures.

[0036] Specifically, the main body section 1 is 360mm long and adopts a three-spindle structure. The warp yarns, specifically the ground warp and the skein warp, are twisted in a one-to-one twist pattern, with each of the two traction threads being 260mm long. The main body section 1 is a hollow tube with a circumference of 9mm. The thickness of the artificial ligament is 1.8–1.9mm. This artificial ligament structure provides a tensile strength of 1500N, exhibits structural stability, and is simple to weave, specifically including the following steps:

[0037] (1) Warp threading: The warp is threaded on the loom using the forward threading method. The warp yarns are 14 strands of 500D / 3 polyester twisted yarn. The ground warp and skein warp are in a one-twist-one-twist configuration, using 49# steel reeds, 2 yarns / reed. To make the edges of the left and right folds of the tubular fabric smooth, a special yarn with high tension is threaded into each end of the warp yarns. The special yarn is 1600D / 3 ultra-high molecular weight polyethylene screen twisted yarn. The special yarn is threaded separately in an independent heald frame. During weaving, the special yarn is not woven into the fabric. When the fabric is removed from the loom, the special yarn can be pulled out.

The shape or size of the plies may be uniform or different. Plies may be composed of homogeneous materials or a combination of multiple materials. Due to the different thicknesses and strengths of the warp and weft yarns, different resistances, as well as different pore sizes and porosities, can be achieved under the same structure, for example, pore sizes of 0.1–1 cm and porosities of 10–90%.

[0041] It is understood that the main body section in the above embodiment adopts three-spindle yarn, but it can also adopt any one of one-spindle yarn, five-spindle yarn, seven-spindle yarn, or nine-spindle yarn.

The special yarn is 1600D / 3 ultra-high molecular weight polyethylene screen twisted yarn. The special yarn is threaded separately in an independent heald frame. During weaving, the special yarn is not woven into the fabric. When the fabric is removed from the loom, the special yarn can be pulled out.
