Dear WW: I haven't been in an OR for many years, and so have not idea what suture materials are used today. I suspect however, that nylon and other new synthetic materials have largely replaced gut, except possibly for buried sutures that have to be slowly absorbed.
And I suppose that string music is no longer the tail of a horse being drawn across the entrails of a cat.
It may well be that children are no longer told that dragonflies are darning needles capable of sewing their mouths shut. Most of the dragonfly habitat is now shopping mall.
