Abstract

A sewing machine for forming stitches in a substrate, for example, in forming stitches in tissue during surgery, comprises a needle for passing thread into the substrate from one side thereof at a first location and for withdrawing the thread from the substrate at a second location spaced from the first location. The needle is removably operable solely from the said one side of the substrate. A stapling machine is also disclosed operating on similar principles for similar purposes.
