Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

example (b): referring to fig. 1 to 4, a full suture anchor comprises asuture 1 and athread anchor 2, wherein thethread anchor 2 is a flexible fixing member, thesuture 1 and thethread anchor 2 can slide relatively, thethread anchor 2 is formed by weaving, and at least one section of thesuture 1 and the thread anchor are woven to form a core-spun structure section 11. The core-spunstructural section 11 is a section through which thesuture 1 is passed from inside thebraided wire anchor 2, which section shortens in length and expands in wire diameter to form a knot as the suture is tightened when the wire anchor is contracted relative to the suture. The two ends of thesuture 1 extend to be connected with thethread anchor 2 through penetration to form a penetration structure section, and the thread anchor is folded and expanded to form a knot when the suture is tensioned. The core-spun structural section and the interpenetration structural section of the full suture anchor are symmetrically distributed in the anchoring center. As shown in fig. 2 and 4, the wire anchor of the full suture anchor is collapsed to form an anchoring portion disposed within the bone tissue passage.

The utility model relates to a full suture anchor nail, full suture anchor nail's characteristics lie in reaching sufficient pull-out strength and higher fixed strength with a small amount of material, and the diameter is little and the shallow bone destruction has been reduced to a certain extent that inserts. The flexible material and the structural design are utilized to enable the full suture anchor to have the characteristic of shape variability, the full suture anchor is implanted in a shape of slender and small diameter, the anchor is forced to deform to form a knot through external force after the full suture anchor is implanted, the fixation effect is achieved, the size is small, and the fixation strength is high.

The utility model discloses full suture anchor has two parts to constitute, includingsuture 1 and flexible fixedpart line anchor 2 promptly, can relative slip betweensuture 1 and flexible fixedpart line anchor 2. The flexiblefixation member anchor 2 is connected to thesuture 1 in a manner that includes piercing and cored, both symmetrically disposed on either side of the suture anchor, as shown in fig. 1, 2, 3, 4.

The utility model disclosesstylolite 1 generally adopts the ultra high molecular weight polyethylene yarn to make, and common specification includes 3-0 to 2 # stylolite, and stylolite length 900 supplyes 1200mm, and the stylolite can be by one or many and constitute side by side. Thethread anchor 2 can be made of ultra-high molecular weight polyethylene yarn or polyester yarn, and the diameter of the thread anchor is generally controlled to be 0.5-2mm, and the length of the thread anchor is controlled to be 10-30 mm.

The braidedwire anchor 2 is in a interspersed or cored configuration with the suture 1: the core-spun structural segment is characterized in that an internal suture thread is passed through the interior of the braided wire anchor. When the thread anchor contracts relative to the suture thread, the contraction characteristic of the core-spun structure section is that the length of the thread anchor at the section is shortened and the thread diameter is enlarged to form a knot after the suture thread is tensioned, and meanwhile, the folding parts at two sides are clamped in the bone passage. Compared with the implanted bone tissue channel used by the fully-folded knot anchor, the structure is shorter, and the core-spun section wire anchor plays a role in expanding the diameter of the whole wire anchor.

As shown in fig. 2 and 4, the implantation of the thread anchor can be realized by means of an inserter, and firstly, the thread anchor folded and bent into a U-shaped structure is pushed and inserted into an operation hole by using a metal rod, and after the thread anchor is implanted into thebone tissue 3, thesuture 1 is pulled to make the suture anchor become a knot. So that the anchor does not fall out of the hole of the bone bore. The diameter of the formed knot can be expanded by 2-3 times, the anti-extraction force after the knot is implanted into the bone tissue reaches 100-400N, and the knot plays a good role in fixation.

Fig. 1 and 2 show a full suture anchor having a core-spun structure section and a threaded structure section, in use, as shown in fig. 2. Fig. 3 and 4 illustrate another type of all suture anchor having a first cored-out structure section 101, a second cored-out structure section 102, and a third cored-out structure section 103, as shown in fig. 4, in use.

The processed product consists of two parts, namely a preset suture and a thread anchor, wherein the thread anchor can move on the preset suture in a telescopic way. The expansion may be provided by folding the middle section of the suture anchor after the pre-placed suture is straightened, as shown in fig. 2 and 4. The thread anchor with the shape is matched with an implanting instrument for use, the thread anchor is implanted into human bone tissues, and the preset suture is pulled after the implantation to ensure that the thread anchor is contracted longitudinally and expanded transversely. The resistance created by the expansion is sufficient to allow the wire anchor to be anchored in the bone tissue, completing the anchoring.

The implanted anchor becomes a bending structure and is fixed in the bone, the flexible fixing part can be changed in shape at will, the bone path required during fixing is small, and the bone removal amount is small; easy to remove and repair, can slightly enlarge the bone tunnel during repair, and adopts a large-size flexible fixing part. Even if the full suture anchor made of the flexible material is pulled out of the bone canal after being implanted, the full suture anchor does not damage the surrounding joints and the bone surface.

The above description is only an embodiment utilizing the technical content of the present disclosure, and any modification and variation made by those skilled in the art can be covered by the claims of the present disclosure, and not limited to the embodiments disclosed.
