System for manufacturing electrosurgical seal plates
A system for the manufacture of an end effector assembly which is configured for use with an electrosurgical instrument configured for performing an electrosurgical procedure is provided. The system includes a photolithography module that is configured to etch one or more pockets on a seal surface of the seal plate. A vacuum module is configured to raise, transfer and lower a spacer from a location remote from the pocket(s) on the seal plate to the pocket on the seal plate(s). An adhesive dispensing module is configured to dispense an adhesive into the pocket on the seal plate. An optical module is configured to monitor a volume of the adhesive dispensed within the pocket and monitor placement of the spacer within the pocket.
1. An end effector configured for use with an electrosurgical instrument, the end effector comprising:
a first jaw member having a first sealing surface including a plurality of flanges configured to secure the sealing surface to an overmolding material; and
a second jaw member operably coupled to the first jaw member such that at least one of the first jaw member or the second jaw member is movable relative to the other, the second jaw member having a second sealing surface and a spacer disposed within a pocket defined in the second sealing surface of the second jaw member, the spacer configured to maintain a desired gap distance between the first and second sealing surfaces when the first and second jaw members are in a closed position.
2. The end effector according to claim 1 , wherein the pocket has a depth of 0.002 inches.
3. The end effector according to claim 1 , wherein the pocket extends through a partial depth of the second sealing surface.
4. The end effector according to claim 1 , wherein the spacer extends from the second sealing surface a distance that ranges from 0.005 inches to 0.01 inches.
5. The end effector according to claim 1 , wherein the spacer includes a hemispherical configuration.
6. The end effector according to claim 1 , wherein the spacer includes a cylindrical configuration.
7. The end effector according to claim 1 , wherein the spacer includes a square configuration.
8. The end effector according to claim 1 , wherein the spacer includes a triangular configuration.
9. The end effector according to claim 1 , wherein a plurality of spacers is disposed within the pocket defined in the second jaw member.
10. The end effector according to claim 9 , wherein the plurality of spacers is arranged in a grid-like configuration.
11. The end effector according to claim 10 , wherein each of the plurality of spacers is spaced relative to each other.
12. The end effector according to claim 1 , wherein at least one of the first sealing surface or the second sealing surface includes a knife slot.
13. The end effector according to claim 1 , wherein the plurality of flanges extend from a side of the first sealing surface.
