Abstract
The invention provides a material for artificial ligament, which is characterized by comprising compound yarns for bearing load and an earth tissue structure for bounding the compound yarns; each compound yarn comprises an inner core and an external protective layer wrapping the inner core; and the compound yarns are weaved into the earth tissue structure in a weft insertion manner. The material for artificial ligament has the characteristics of simple manufacturing method, high tensile strength, and good fatigue restraint ability and biocompatibility, and can be adjusted within certain range of elongation; and meanwhile, when the artificial ligament made of the material is fixed in a suspension manner, the bearing fiber at the fixed position can not be easy to damage due to the outer layer wrapped with wear-resisting polyester fiber.
Description
Technical field
The present invention relates to a kind of medical embedded material, particularly relate to a kind of artificial ligament material that can be used for biological joint.
Background technology
The artificial ligament that substitutes articular ligament has multiple, mainly comprises biomechanics characteristic and biocompatibility for the requirement of such artificial ligament.In the research of artificial ligament, the modification of raw material, raw material combination mode and raw material is an emphasis, and wherein the raw material combination mode not only has influence on the biomechanics characteristic of final finished, also might have influence on final finished fixed form in vivo.
At present, on artificial ligament raw material combination mode, domestic adopt short fiber non-woven felt or multiple layers of different materials combinations more.Its drawback is the short fiber non-woven felt in permanent application process, and fiber might come off from the felt body, and the intensity of short fiber non-woven felt body is lower and percentage elongation is higher, and discomfort is fit to do the higher ligament of requirement of strength; The multiple layers of different materials combination, the anti-interlayer shear poor-performing of material, and processing technique is complicated.
Summary of the invention
The purpose of this invention is to provide a kind of artificial ligament material that can be used for biological joint, the artificial ligament of sewing up with this material has the good mechanical performance and can satisfy suspension artificial ligament fixed form.
In order to achieve the above object, a technical scheme of the present invention has provided a kind of artificial ligament and used material, it is characterized in that: comprise the ground organizational structure of complex yarn with the constraint composite yarn of bearing load, complex yarn inweaves the ground organizational structure with the inlaid thread mode.
Preferably, described complex yarn comprises the outer protection layer that inner core is outer with being coated on inner core, and inner core is the high-strength multifilament of polyester full-drafting, and the outer protection layer is the wear-resisting type polyester capillaries, and the outer protection layer coats inner core according to the segmentation of ligament size.
Preferably, said inner core is applied certain twist forward or backwards, to guarantee that after the artificial ligament finished product is made completion the high-strength multifilament of polyester full-drafting that is positioned at human synovial has required certain anglec of rotation.
Preferably; Said wear-resisting type polyester capillaries adopts weaving method; Size according to final artificial ligament finished product; Be coated on part as the polyester full-drafting high strength yarn of the inner core outside, coated length greater than the artificial ligament finished product in organism, be used to suspend in midair fixed segment length and only parcel be in abarticular inner core.
Preferably, said ground organizational structure is a knitted structure.
Compared with prior art, the present invention has following characteristics:
The material method that is used for artificial ligament provided by the present invention is simple; Material has that hot strength height, anti-fatigue performance are good, the characteristics of scalable, good biocompatibility in the percentage elongation certain limit; Simultaneously when the artificial ligament by this material adopts the suspension fixing means, at the bearing fiber of bearing because outer coating resistant polyester fiber is difficult for impaired.

Fig. 2 is the special-purpose fabric construction sketch map of artificial ligament.
The specific embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, for being used for the complex yarn 1 of bearing load in the artificial ligament material, comprise inner core 3 and outer protection layer 4.Inner core 3 is the high-strength multifilament of polyester full-drafting, need apply certain twist forward or backwards to the high-strength multifilament of this polyester full-drafting, after guaranteeing that material is processed the artificial ligament finished product, is positioned at IA fibre bundle and has required certain anglec of rotation.Outer protection layer 4 is the wear-resisting type PFY, according to final artificial ligament finished size, is coated on part as the high-strength multifilament of the polyester full-drafting of inner core 3 outside.Coated length is used to suspend in midair fixed segment length greater than artificial ligament in organism, be in IA fibre bundle but can not be coated to.Outer protection layer 4 plays the protective effect to inner core 3 high-strength multifilament in the bearing of artificial ligament finished product.
As shown in Figure 2, use the material monolithic structure for artificial ligament, comprise complex yarn 1, ground organizational structure 2.Complex yarn 1 serves as a contrast in knitting ground of the people organizational structure 2 with the mode of inlaid thread.Requirement is in the course of processing, and ground organizational structure 2 guarantees to obtain construction unit as shown in Figure 2 on yarn configuration, organizational structure and weaving process.In a of artificial ligament material portion section, c portion section, complex yarn 1 is fettered by the ground stitch yarn 5 in the ground organizational structure 2; B portion section is a unprotect layer portion section in the complex yarn 1, and is not fettered by ground stitch yarn 5; D portion section is the complex yarn 1 with outer protection layer 4.
