Detailed Description
The present invention will be described in further detail with reference to the following examples and drawings.
As an embodiment, the utility model provides an amniotic membrane material product for tendon injury repair, as shown in fig. 1, including amniotic membrane body 1, amniotic membrane body 1 includes carrier layer 101, auxiliary material layer 102 and amniotic membrane layer 103, between carrier layer 101 and the auxiliary material layer 102, all be connected through tie coat 104 between auxiliary material layer 102 and the amniotic membrane layer 103, still be equipped with inertia polyvinylidene fluoride layer 105 between auxiliary material layer 102 and the amniotic membrane layer 103, be connected through tie coat 104 between auxiliary material layer 102 and inertia polyvinylidene fluoride layer 105, inertia polyvinylidene fluoride layer 105 and the amniotic membrane layer 103. The dimensions of the drawings in the present application are appropriately scaled.
The utility model provides a new amniotic membrane material product for tendon damage is restoreed, this amniotic membrane body for in the prosthetic amniotic membrane material product of tendon damage includes carrier layer, auxiliary material layer and amniotic membrane layer, and still is equipped with inertia polyvinylidene fluoride layer between auxiliary material layer and the amniotic membrane layer, and this setting can make the texture of this amniotic membrane material product harder, the operation in the operation of being convenient for.
The auxiliary material layer is made of gauze, synthetic fiber dressing, polymeric film dressing, foaming polymer dressing or hydrocolloid dressing, the inert polyvinylidene fluoride layer is used for resisting solvent corrosion and the like, and the carrier layer, the auxiliary material layer and the inert polyvinylidene fluoride layer can also make the texture of the amniotic membrane layer harder, so that the operation in the operation is facilitated.
As shown in fig. 2, in this embodiment, a plurality of absorbable sutures 2 are disposed on the amniotic membrane body 1 at intervals along the length direction of the amniotic membrane body 1, the absorbable sutures 2 are inserted into the amniotic membrane body 1, and two ends of the absorbable sutures 2 can be pulled along the width direction of the amniotic membrane body 1.
