Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
As shown in Fig. 2, the cured artificial ligament in interval provided by the utility model includes woven fabric 1, woven fabric 1 in embodiment
Multiple solidification bands 21 are formed on length extending direction, woven fabric 1 forms former ribbon in the two neighboring part solidified between band 21
22, the multiple solidification band 21 is taking turns flow arrangement along 1 length direction of woven fabric with multiple former ribbons 22.In the length along woven fabric 1
On extending direction, solidification 21 length of band is 3~10mm, and former 22 length of ribbon is 10~50mm, and the length of multiple original ribbons 22 is deposited
In difference, when doctor needs the braid over braid of specific length, need to be only cut out on suitable two solidifications band 21, when
In right preference, the length of former ribbon 22 is also possible to equal, processes relatively simple, but cutting in braid over braid in this way
Taking accordingly can be insufficient in the selection of length.
As shown in Figure 1, woven fabric 1 includes braiding layer 31 and collagen film 32, the collagen film 32 is connected to braiding
On one of end face of 31 through-thickness of layer, two end faces or on whole two end faces.Collagen film 32 passes through Static Spinning
Be processed into, and spraying, suture or processed by way of directly fitting in braiding layer 31.The braiding layer 31 includes warp
Yarn 310 and weft yarn, the warp thread 310 extend along 1 width direction of woven fabric, and the weft yarn extends along knitted body length direction, implement
In example, the material of warp thread 310 and weft yarn is following any or appoints a variety of: collagen and polyvinyl alcohol composite monofilament, collagen and being gathered
Vinyl alcohol compound multifilament yarn, polylactic acid base polymer monofilament, polylactic acid base polymer multifilament, specifically, such as PLLA, PLGA,
The materials such as PGLA, PGA.In change case, the woven fabric 1 is only made of braiding layer 31.It is as shown in Figure 3, Figure 4, described in preference
Former ribbon 22 includes the soft band 221 of longitude and latitude and the soft band 222 of weft, and the braiding layer 31 of the soft band 221 of longitude and latitude includes warp thread 310 and latitude
Yarn, the braiding layer 31 of the soft band 222 of weft only include weft yarn, and in use, the soft band 222 of weft is located in articular cavity,
Since rigidity is relatively low, it is more suitable for the activity in joint；Preferably, it is processed when in braiding layer 31 by collagen film 32,
Covering collagen film 32 is not had on the soft band 222 of weft.Preferably, the weft yarn includes the first weft yarn 311 and the second weft yarn
312,311 material of the first weft yarn is degradation material, and 312 material of the second weft yarn is non-degradable material, along 1 width of woven fabric
On extending direction, the first weft yarn 311 is taken turns flow arrangement with the second weft yarn 312 or is sequentially arranged.
Solidification band 21 in woven fabric 1 be melted by blanching or ultrasonic heat it is standby, make braid over braid hot melt solidification, when in use,
As needed, it is cut into certain length, crop position is the solidification band 21, and crop position is made not occur loose fiber.This reality
Include the following two kinds structure with novel middle woven fabric 1: the first is only comprising braiding layer 31；Second includes braiding layer 31 simultaneously
With collagen film 32.The processing is simple for the first structure, and production cost can be greatly saved while reaching therapeutic effect；The
Two kinds of structures are after implanting, and as collagen film 32 is gradually degraded, human body itself connective tissue is grown into tough
Band micropore, forms overall structure, accelerates wound healing.And braiding layer 31 is because of its excellent mechanical strength and good flexibility,
It can be made to keep mechanically stable in activity repeatedly, restore joint motion, while with the growth of itself connective tissue, braiding
The gradually slowly degradation of layer 31, combines together with tissue, to reach comparatively ideal ligament reconstructive reparation.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.In the absence of conflict, the spy in embodiments herein and embodiment
Sign can be arbitrarily combined with each other.
