ABSTRACT:
A pericardial endoscopic scissors is provided and generally comprises a hollow tube with a clevis coupled thereto, first and second scissor blades laterally offset from each other and both having elongate straight blade edges angled at about 45 degrees relative to the hollow tube, with the first scissor blade pivotally engaging the clevis so that its blade can angle about 90 degrees relative to the hollow tube in an open position, a rod extending through the hollow tube and coupled to the pivoting first scissor blade, and an actuator engaging the rod and imparting reciprocal motion thereto, which reciprocal motion is translated to pivotal motion of the first scissor blade. The fixed second scissor blade is provided at its distal end with an integral probe element which is laterally offset relative to and indented from the straight blade edge. The probe element extends away from the second scissor blade toward the first scissor blade, and the second scissor blade together with the probe element provide a rounded presenting surface. Likewise, the distal end of the first scissor blade presents a rounded surface substantially adjacent the rounded presenting surface of said second blade member. The probe element of the second scissor blade does not contact the first scissor blade during a scissor cutting action.
