Patent ID: 8770249

Claim:
An RF energized plastic tubing sealer for sealing plastic tubing placed intermediate a fixed jaw and movable ground jaw comprising in combination: a movable ground jaw comprising: a) a post; b) a semi-cylindrical surface formed as part of said post that is interconnected at both ends to reversely curved troughs; c) a pair of longerons extending from said post and engaged with the tubing sealer to permit rectilinear translation of said post relative to a fixed jaw, and a fixed jaw mounted on the tubing sealer that includes a strip having a planar surface of electrically conductive material and wherein the longitudinal center of said semi-cylindrical surface of the moveable ground jaw is adjacent and aligned with the strip of the fixed jaw to urge focus of RF transmitted energy from the fixed jaw to the longitudinal area of the cylindrical surface of the moveable ground jaw physically closest to the strip.
