Abstract: A surgical instrument is provided, namely surgical scissors. The surgical instrument has a removable actuating rod which, in conjunction with the clevis and a tube, provides means for securing blades of the scissors. The tube prevents a removable pivot pin of the blades from becoming displaced from the clevis of the instrument. When the actuating rod is removed from the surgical instrument the pivot pin may be removed and, thus, the blades of the scissors may be removed for cleaning and/or replacement. The tube provides the tension and further constrains the scissor blades in a manner which results in the consistent and effective cutting performance of the scissors post assembly.

Abstract: A surgical instrument is provided, namely surgical scissors. The surgical instrument has liquid-tight heat-shrunk protective covering located at the business end of the surgical instrument which prevents contamination and damage to moving parts of the instrument which otherwise typically occurs between an extended tube portion of the surgical instrument and a head portion of the surgical instrument. Further, the liquid-tight heat shrunk protective covering provides electrical insulation all the way to the distal tip of a clevis of the surgical instrument by use of a rubber (for example silicone) seal. The surgical instrument has a first blade and a second blade secured to the clevis. The first blade and second blade both have a triangular-shaped back end which allows the blades to fully extend without the back ends extending outside of the instrument.
