A surgical fastener of plastic or plastic-like material includes initially separate fastener and retainer members. The fastener member has at least two parallel prongs, each of which fits into a respective one of at least two apertures in the retainer member. The prongs twist as they enter the apertures. Then the prongs return to their initial orientation in which they interlock with the retainer member to form a finished fastener. The fastener is applied by forcing the fastener member prongs through the tissue to be fastened with the aid of metal pins contiguous with each prong. The pins are automatically withdrawn from the tissue after the prongs interlock with the retainer member and before the fastened tissue is removed from the fastener applying apparatus.
A surgical fastener of plastic-like material comprising: a fastener member including a base and at least two spaced substantially parallel prongs extending substantially perpendicularly from the base; and a retainer member including at least two apertures, each aperture being adapted to receive and
A surgical fastener of plastic-like material comprising: a fastener member including a base and at least two spaced substantially parallel prongs extending substantially perpendicularly from the base; and a retainer member including at least two apertures, each aperture being adapted to receive and retain the free end of a respective one of the prongs, each aperture including (a) cam surface means for contacting the associated prong and causing it to twist about its longitudinal axis as it initially enters the aperture and then allowing the prong to untwist after the prong has penetrated a predetermined distance into the aperture and (b) interlocking surface means for interlockingly engaging the associated prong to prevent withdrawal of the prong from the aperture after the prong has been allowed to untwist by the cam surface means.
