Description

Absorbable ligament with curing band

Technical Field

The present invention relates to the field of medical devices, and in particular to an absorbable ligament with a curing band.

Background

When the knee joint is excessively turned in or out, the pulled ligament is damaged by tearing, breaking and the like due to exceeding physiological load, and the diseases mainly represented by swelling, pain, dysfunction, pressure pain points and the like of the knee joint are treated. The knee is straightened, the outer side of the knee or leg is hit or pressed by strong violence, so that the knee is excessively abducted, and the medial collateral ligament can be partially or completely broken. In contrast, the medial knee or leg is struck or heavily stressed by violence, causing excessive adduction of the knee, partial or complete rupture of the lateral collateral ligaments, and in severe trauma cases, simultaneous injury of the collateral ligaments, the cruciate ligament, and the meniscus.

Ankle sprains are very common in athletic injuries, with supination injuries of the ankle, i.e., injuries to the lateral collateral ligaments of the ankle, including injuries to the anterior talofibular ligament, the calcaneofibular ligament, and the posterior talofibular ligament being the most common. The supination injury is in fact a combination of actions including pronation of the ankle, varus of the calcaneus navicular joint and adduction of the forefoot, which are difficult to break apart during the injury. During exercise, the body loses the center of gravity for some reason, or the foot of the user is stepped on when jumping up and landing, or the foot is stepped on and stumbled during exercise, and the like, the action of supination of the foot can be generated, so that the lateral ligament of the ankle is damaged.

For the treatment of collateral ligament injuries, ligament dead center reconstruction should be performed when the ligament is torn off from the dead center and is difficult to join directly. At this time, artificial collateral ligaments are needed, the length of collateral ligaments on the market is 400mm,500mm,600mm or 800mm, in actual clinical use, doctors need to cut collateral ligaments into needed length, and collateral ligaments are strip-shaped fabrics with a woven structure, when the collateral ligaments are cut by scissors, the ends of the collateral ligaments are loose, ligament reconstruction is difficult to suture, loose fibers are easy to fall off particles, and inflammatory reaction is easy to cause.

As shown in fig. 1 to 5, the absorbable ligament with a curing band provided by the present invention comprises a round bar structure 4, and the round bar structure 4 is manufactured by the following steps: step S1: forming a woven fabric layer 31 by using warp yarns 310 and weft yarns on a loom, and paving collagen films 32 on one or both end surfaces of the woven fabric layer 31 in the thickness direction to form a woven fabric 1; step S2: a plurality of woven fabric curing belts 21 are processed in the length extending direction of the woven fabric 1 by a hot stamping or ultrasonic hot melting method, and a woven fabric raw webbing 22 is formed at the part of the woven fabric 1 between two adjacent woven fabric curing belts 21; step S3: cutting out a fabric 1 with a required length along the fabric curing belt 21, wherein two ends of the cut fabric 1 along the length direction respectively form a first knitting part 11 and a second knitting part 12; step S4: the fabric 1 is wound around the long axis of the fabric 1 as a rotation axis, both ends of the wound fabric 1 are sewn and fixed by a hook or a suture needle to obtain a round bar structure 4, the first bone tunnel implant portion 41 and the second bone tunnel implant portion 42 correspond to the first woven portion 11 and the second woven portion 12, respectively, the fabric solidified tape 21 and the fabric raw webbing 22 correspond to the bone tunnel solidified tape 51 and the rolled raw webbing 52, respectively, and the fabric woven layer 31 and the collagen film 32 correspond to the rolled woven layer 53 and the absorbable layer 54, respectively. The bone tunnel-curing strips 51 are present on the bone tunnel-implant, the round bar structure 4 forms rolled raw webbing 52 at a portion between two adjacent bone tunnel-curing strips 51, the plurality of bone tunnel-curing strips 51 and the plurality of rolled raw webbing 52 are alternately arranged in an axial direction along the round bar structure 4, and lengths between the plurality of rolled raw webbing 52 are equal or different. As shown in fig. 12, the rolled braid 53 and the absorbable layer 54 are alternately arranged in the radial direction of the cross-section of the bone tunnel implant. Accordingly, in the extending direction of the length of the fabric 1, the length of the fabric curing belt 21 is 3-10 mm, the length of the fabric original webbing 22 is 10-50 mm, and the lengths of the plurality of original webbing are different, when a doctor needs a webbing with a specific length, only the two proper fabric curing belts 21 need to be cut, however, in a preferred embodiment, the lengths of the fabric original webbing 22 may be equal, so that the processing is relatively simple, but the cutting length of the fabric 1 is correspondingly insufficient.

As shown in fig. 11, in the embodiment, the woven fabric 1 includes a woven layer 31 and a collagen film 32, and the collagen film 32 is connected to one or both of the two end surfaces of the woven layer 31 in the thickness direction. The collagen film 32 is formed by an electrostatic spinning process and is processed on the braid 31 by spraying, sewing or direct bonding. After the invention is implanted into a body, the connective tissue of a human body gradually grows into ligament micropores along with the gradual degradation of the collagen membrane 32 to form an integral structure, so that the wound healing is quickened. The braid 31 can keep mechanical stability in repeated movements due to excellent mechanical strength and good flexibility, and the joint movements are recovered, meanwhile, the braid 31 is gradually and slowly degraded along with the growth of connective tissues, and is integrated with tissues, so that more ideal ligament reconstruction and repair are achieved. The woven fabric layer 31 includes warp yarns 310 and weft yarns, the warp yarns 310 extend along the width direction of the woven fabric layer 31, and the weft yarns extend along the length direction of the woven fabric layer 31, in which, in an embodiment, the warp yarns 310 and the weft yarns are made of any one or more of the following materials: the material of the collagen-polyvinyl alcohol composite monofilament, collagen-polyvinyl alcohol composite multifilament, polylactic acid polymer monofilament, polylactic acid polymer multifilament, or the like is, for example, PLLA, PLGA, PGLA, PGA. In a preferred embodiment, as shown in fig. 4 and 5, the original webbing includes a warp and weft soft belt 221 and a weft soft belt 222, the woven fabric layer 31 of the warp and weft soft belt 221 includes warp yarns 310 and weft yarns, and the woven fabric layer 31 of the weft soft belt 222 includes only weft yarns; as shown in fig. 3, the round bar structure 4 further forms an intra-articular free wire portion 43 in the axial direction, and the first bone tunnel implant portion 41, the intra-articular free wire portion 43, and the second bone tunnel implant portion 42, and the weft soft belt 222 corresponds to the intra-articular free wire portion 43. During use, the intra-articular free wire portion 43 corresponding to the weft tape 222 is located in the joint cavity, and is more suitable for joint movement due to its relatively low rigidity. Of course, in the preferred embodiment, as shown in fig. 1 and 2, the woven fabric tape 22 may also include only the warp and weft soft tapes 221, and accordingly, the round bar structure 4 forms only two bone tunnel implants, i.e., the first bone tunnel implant 41 and the second bone tunnel implant 42, in the axial direction, which is simpler to manufacture, but cannot well accommodate the movement of the joint after being installed in the body. Preferably, the soft weft tape 222 is not covered with the collagen film 32 when the collagen film 32 is processed on the braid 31. Preferably, the weft yarns include a first weft yarn 311 and a second weft yarn 312, the first weft yarn 311 is made of a degradable material, the second weft yarn 312 is made of a non-degradable material, and the first weft yarn 311 and the second weft yarn 312 are alternately arranged or sequentially arranged along the width extending direction of the fabric 1. Preferably, in step S4, both ends of the woven fabric 1 in the width direction may be rolled on the same surface, and the cross-sectional shape after the rolling is completed may be spiral or C-shaped, or may be rolled on two different upper and lower planes, and the cross-sectional shape after the rolling is completed may be 8-shaped.

As shown in fig. 9 and 10, a plurality of petals 71 are cut out from the two bone tunnel implants, i.e., the first bone tunnel implant 41 and the second bone tunnel implant 42, so that the bone tunnel implant has a petal-shaped cross section, and the petal-shaped bone tunnel implant includes the petals 71, a first suture 81, and a second suture 82. A plurality of the petals 71 are arranged along the circumferential direction, and a first suture 81 is sewn on the petals 71 along the circumferential direction of the single petals 71; the second suture 82 is sewn to the bone tunnel implant along the circumferential direction of the bone tunnel implant's outer contour. Under the constraint of the first suture thread 81, the valve bodies 71 are shaped like a circle, two adjacent valve bodies 71 cannot be closely close, but form a containing gap 72, a filling piece 9 is arranged in the containing gap 72, and the filling piece 9 is made of degradable materials. In the actual use process, after the filling piece 9 is plugged into the object containing gap 72, the second suture line 82 is used for sewing, so that the flap 71 has an extrusion effect on the filling piece 9 to prevent the filling piece 9 from falling off, when the filling piece 9 is implanted into a bone cavity, degradation can be continuously carried out, and human ligament tissues can enter a space generated after the degradation of the filling piece 9, so that the connection area between the flap and the bone tunnel implantation part is increased, and the connection stability is further increased; when the ligament tissue of the human body fills the containing gap 72, the extrusion force between the valve body 71 and the valve body 71 can further strengthen the fixation effect on the ligament tissue of the human body.

As shown in fig. 6 to 8, a central skeleton 6 may be further added to the interior of the bone tunnel implant, the central skeleton 6 is made of a memory alloy, the central skeleton 6 includes a main bone 61 and a plurality of branch bones 62, the plurality of branch bones 62 are connected to both ends of the main bone 61 in the width direction along the length extending direction of the main bone 61, and the central skeleton 6 is capable of being switched between two states, namely, a storage state and a distraction state: in the storage state, the branch bones 62 are mutually close in the circumferential direction; in the expanded state, the struts 62 are spaced apart from one another in the circumferential direction. In actual use, the central skeleton 6 can be designed as: under a low-temperature environment, such as a zero-degree ice water mixed phase, the central framework 6 is in a collection state; when subjected to a temperature environment approaching body temperature, such as degrees celsius, the central framework 6 becomes a distracted state. When the first bone tunnel implantation part 41 and the second bone tunnel implantation part 42 of the round bar structure 4 are implanted, the central framework 6 is in a storage state, and the round bar structure 4 can be more easily penetrated into a bone tunnel; after the implantation operation is finished, the central framework 6 is changed from a collection state to a spreading state under the action of body temperature, on one hand, the round bar structure 4 can be spread in the radial direction, the contact force between the first bone tunnel implantation part 41 and the second bone tunnel implantation part 42 and the corresponding bone tunnels is increased, and the fixing strength is further increased; on the other hand, a cavity is formed in the round bar structure 4, so that a space is provided for the growth of the human body self-tissue, and the integration of the ligament graft and the human body self-tissue is promoted. Therefore, the arrangement of the center frame 6 can achieve the three effects. In the preferred embodiment, the central skeleton 6 may not include the supporting ribs 62, but is entirely in a cambered surface shape, in the storage state, the circumferential outline area of the central skeleton 6 is reduced, in the opening state, the circumferential outline area of the central skeleton 6 is increased, and the structure makes the opening force larger and the structure more stable, but due to the larger surface area of the cambered surface, the combination of the human body tissue and the yarn inside the round bar structure 4 is not facilitated, and the final fixing effect is reduced.

The foregoing describes specific embodiments of the present invention. It is to be understood that the invention is not limited to the particular embodiments described above, and that various changes and modifications may be made by one skilled in the art within the scope of the claims without affecting the spirit of the invention. The embodiments of the present application and features in the embodiments may be combined with each other arbitrarily without conflict.
