Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
98 words
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.
Claim 2
Dependent Claim
98 words
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.
Claim 3
Dependent Claim
57 words
A machine according to claim 1, comprising an anvil disposed in the slot adjacent the other of said staple end portions and arranged so that when said one staple end portion is driven through the double layer of substrate it strikes the anvil and is deformed thereby into a position closely adjacent said other staple end portion.
Claim 4
Dependent Claim
88 words
A stapling machine for inserting a 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 and mounting means for mounting the machine on an end of an endoscope.
Claim 5
Dependent Claim
88 words
A stapling machine for inserting a 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 and mounting means for mounting the machine on an end of an endoscope.
Claim 6
Dependent Claim
57 words
A machine according to claim 3, comprising an anvil disposed in the slot adjacent the other of said staple end portions and arranged so that when said one staple end portion is driven through the double layer of substrate it strikes the anvil and is deformed thereby into a position closely adjacent said other staple end portion.
Claim 7
Dependent Claim
74 words
A stapling machine for inserting a staple in a substrate, comprising means defining a slot open towards the substrate, the slot being configured to receive at least one staple, means for drawing a double layer of the substrate into the slot, and means for forcing said staple into a disposition in which it staples the double layer of substrate together, said drawing means comprising a channel communicating with said slot for supplying suction thereto.
Claim 8
Dependent Claim
74 words
A stapling machine for inserting a staple in a substrate, comprising means defining a slot open towards the substrate, the slot being configured to receive at least one staple, means for drawing a double layer of the substrate into the slot, and means for forcing said staple into a disposition in which it staples the double layer of substrate together, said drawing means comprising a channel communicating with said slot for supplying suction thereto.
Claim 9
Dependent Claim
74 words
A stapling machine for inserting a staple in a substrate, comprising means defining a slot open towards the substrate, the slot being configured to receive at least one staple, means for drawing a double layer of the substrate into the slot, and means for forcing said staple into a disposition in which it staples the double layer of substrate together, and mounting means for mounting the stapling machine on an end of an endoscope.
Claim 10
Dependent Claim
74 words
A stapling machine for inserting a staple in a substrate, comprising means defining a slot open towards the substrate, the slot being configured to receive at least one staple, means for drawing a double layer of the substrate into the slot, and means for forcing said staple into a disposition in which it staples the double layer of substrate together, and mounting means for mounting the stapling machine on an end of an endoscope.
