Surgical fastener
View Patent ↗An electrosurgical system is provided and comprises a fastening device including a cartridge configured to retain a plurality of fasteners therein and an anvil configured to form the plurality of fasteners; a plurality of surgical fasteners loaded in the cartridge, at least one of the fasteners includes a backspan, a pair of legs depending from the backspan, and at least one contact pad fabricated from an electrically conductive material on the backspan, wherein at least one of the pair of legs is configured to contact the at least one contact pad upon a formation thereof; and an indicating circuit associated with the fasteners, the indicating circuit including an electrical conduit in electrical contact with the at least one contact pad, wherein the indicating circuit includes an energy source and an indicator, wherein the indicator activates upon one of a proper and improper formation of the fasteners.
1. An electrosurgical system, comprising:
a fastening device including a cartridge and an anvil, wherein the anvil is in juxtaposed relation relative to the cartridge, wherein the cartridge and the anvil have a spaced apart position and an approximated position, and wherein the cartridge is configured to retain a plurality of fasteners therein and wherein the anvil is configured to form the plurality of fasteners;
a plurality of surgical fasteners loaded in the cartridge, at least one of the fasteners includes a backspan, a pair of legs depending from the backspan, and at least one contact pad fabricated from an electrically conductive material on the backspan, wherein at least one of the pair of legs is configured to contact the at least one contact pad upon a formation thereof; and
an indicating circuit associated with the fasteners, the indicating circuit including an electrical conduit in electrical contact with the at least one contact pad, wherein the indicating circuit includes an energy source and an indicator, wherein the indicator activates upon one of a proper formation of the fasteners and an improper formation of the fasteners.
2. The electrosurgical system of claim 1 , wherein upon formation of the fasteners, the legs are configured to either contact a respective contact pad or not contact a respective contact pad to indicate whether the fasteners are properly formed.
3. The electrosurgical system of claim 2 , wherein when the respective legs of each fastener properly contact the at least one contact pad, a circuit loop of the indicating circuit is established, and when the respective legs of each fastener do not properly contact the at least one contact pad, the circuit loop of the indicating circuit is not established.
4. The electrosurgical system according to claim 1 , wherein the indicator activates upon a proper formation of a predetermined number of proper formations of the fasteners.
5. The electrosurgical system according to claim 1 , wherein at least a portion of the backspan of each fastener is non-conductive.
6. The electrosurgical system according to claim 1 , wherein the at least one contact pad of each fastener is electrically isolated from the backspan.
7. The electrosurgical system according to claim 1 , wherein the at least one contact pad comprises a pair of contact pads electrically isolated from one another.
