The suture needle retention device of claim 1 wherein the face of the retention flap is textured. 3. The suture needle retention device of claim 1 wherein the interior surface of the closed end of the protective sheathing is textured. 4. The suture needle retention device of claim 1 wherein the attachment component further comprises at least one retention ridge, each said retention ridge located on the interior surface of the closed end of the protective sheathing, each said retention ridge being oriented substantially horizontally, and each said retention ridge extending into the interior of the protective sheathing from the interior surface of the closed end of the protective sheathing such that at least a portion of said retention ridge is aligned over at least a portion of the bottom slot. 5. A suture needle retention device comprising a retention member, said retention member being needle pervious, said retention member suitably adapted to be pierced by a suture needle such that a portion of the suture needle is embedded within said retention member, said retention member suitably adapted to retain an embedded suture needle securely, and said retention member suitably adapted to release an embedded suture needle when a sufficient extraction force is applied to the suture needle; a protective sheathing, said protective sheathing being needle impervious, said protective sheathing being substantially hollow and having an interior and an interior surface, said protective sheathing having an open end providing access into the interior, said protective sheathing having a closed end that is substantially planar and located substantially opposite the open end, said protective sheathing having a top side and a bottom side, and said protective sheathing suitably adapted to contain at least a portion of the retention member within its interior while exposing another portion of the retention member; and an attachment component, said attachment component comprising a bottom slot, said bottom slot formed into the bottom side of the protective sheathing proximate to the closed end of the protective sheathing and providing access into the interior of the protective sheathing, said bottom slot having a width and a length, said length of said bottom slot oriented substantially parallel with the closed end of the protective sheathing, and said bottom slot being suitably adapted to accommodate an end of the surgical instrument such that the end of the surgical instrument is inserted through the bottom slot into the interior of the protective sheathing, a top slot, said top slot formed into the top side of the protective sheathing proximate to the closed end of the protective sheathing and providing access into the interior of the protective sheathing, said top slot having a width and a length, said width of the top slot being less than the width of the bottom slot, said top slot oriented substantially in alignment with the bottom slot, and said top slot being suitably adapted to accommodate the end of the surgical instrument such that the end of the surgical instrument is inserted through the top slot from the interior of the protective sheathing, and at least one retention ridge, each said retention ridge located on the interior surface of the closed end of the protective sheathing, each said retention ridge being oriented substantially horizontally, and each said retention ridge extending into the interior of the protective sheathing from the interior surface of the closed end of the protective sheathing such that at least a portion of said retention ridge is aligned over at least a portion of the bottom slot, said attachment component suitably adapted to removably attach the suture needle retention device to a surgical instrument without the use of adhesives; whereby the attachment component is integrated with the protective sheathing, and at least a portion of the retention member is contained within the interior of the protective sheathing and the surgical instrument protrudes through the bottom and top slots of the protective sheathing with the end of the surgical instrument protruding from the top slot. 6.
