First Claim
1. A stapling machine for inserting the staple in a substrate, comprising means defining a slot open toward the substrate, the slot being configured to receive at least one staple having opposite end portions which are spaced from one another to define a gap therebetween, means for drawing a double layer of the substrate into the slot and through said gap, means for forcing one of said staple end portions through the double layer of substrate, said drawing means including a channel communicating with said slot for supplying suction thereto to effect said drawing in of the double layer.

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 one side of the substrate. A stapling machine is also disclosed operating on similar principles for similar purposes.
