Abstract: Certain embodiments provide a surgical instrument comprising surgical instrument comprising an device having a functional end and a main handle comprising a distal end coupled to the device. The surgical instrument further comprises an actuation handle insert comprising a number of first rolling components and an actuation tube coupled to the actuation handle insert, wherein the functional end of the device at least partially extends outside of the actuation tube when the device is deactivated. The surgical instrument further comprises levers comprising second rolling components. The surgical instrument further comprises a plurality of rolling elements, wherein each of the rolling elements is placed between one of the second rolling components and one of the first rolling components and pressing one or more of the levers pushes the actuation handle insert forward relative to the device, causing the actuation tube to transition the device from the deactivated state to an activated state.

Abstract: Certain aspects of the present disclosure provide a low friction trocar valve comprising a set of sheets arranged circularly and defining an entry point for the insertion of an instrument. In certain aspects, each sheet of the trocar valve's set of sheets comprises areas that overlap with two adjacent sheets. The trocar valve is formed in an opening of a valve housing coupled to or formed as part of a trocar cannula to provide a sealing mechanism for preventing the escape of pressurized fluids from the trocar cannula.
