Abstract

The present invention relates to the sector of surgery and in particular to an apparatus for forming barbs on the surface of threads for surgical use, both of the absorbable type and of the non-absorbable type. This has been obtained, according to the present invention, by providing an automated apparatus for forming barbs, said apparatus being equipped, in combination, with: means (5, 6) for making incisions in at least one surgical thread; means for unreeling the thread, on which barbs are to be made, from the gathering reel of a known type, on which said thread is wound; means for guiding and positioning said thread properly with respect to said means for making incisions (5, 6); means for truncating said barbed thread to the desired length; and means for gathering the portions of barbed thread.

Abstract

In order to make improved threads provided with barbs for surgical purposes, it is envisaged to use threads of polyhedral or stochastic shape and to provide the barbs on said threads, by making a cut in a point corresponding to an edge of the aforesaid polyhedral or stochastic shapes for each barb, preferably by means of techniques of laser etching that enable also barbs with double tip to be obtained so as to increase the biological and histomorphological interaction with the tissues of the host.
