The present disclosure provides surgical clamps. The clamp has a body with a mouth that opens and closes to permit the body to encircle a bundle of tissue containing a blood vessel which a surgeon wishes to occlude. The clamp also has an articulating arm that rotates on a hinge and passes through apertures of the clamp body. The apertures and/or the articulating arm include ratchet components that permit the surgeon to apply dynamic adjustable tensioning to the tissue and vessel in real time. This dynamic tension permits a surgeon to ensure a specific reduction of blood flow through the vessel.

Tensionable surgical clamp

Disclosed herein are safety devices that are positioned on the end of a fiberoptic cable, such as those used in surgical procedures, to prevent patients and other objects from the risk of burn from light or heat emitted from the end of the cable when not connected to an optical instrument. The disclosed safety devices can be added to the ends of existing cables and/or can be included at the end of cables during manufacture. In some embodiments, the safety device replaces an existing connector at the end of a cable, and in some embodiments the safety device is added in addition to a connector at the end of the cable. In some embodiments, a slit end cover is included over an open end of an adaptor that is mounted on a distal connector of a fiberoptic cable.
