Abstract
A needlescopic scissors end effector assembly includes a pair of jaws or blades pivotable to perform a cutting or shearing operation. The scissors end effector assembly includes a cannula having a diameter between about 1 mm to 5 mm and a needle tip configured for percutaneous operation. The pair of jaws or blades includes cam profile surfaces to interact with an opening defined with the needle tip to actuate opening and closing of the pair of jaws or blades and to prevent backlash effect during the opening and closing of the pair of jaws or blades.
