Abstract
Systems and methods make use of a fluid dispensing control apparatus having a sheath, a tubing system, and a fluid source to facilitate control of fluid during intra-operative defogging, surgical debris deflection, and cleaning of a laparoscope lens during minimally invasive surgery. The sheath has at least one lumen for providing fluid to the distal end of the sheath to clean the laparoscope. At the end of the lumen is a one-way control valve to prevent the uncontrolled flow of fluid from the lumen. The apparatus may also have a syringe assembly wherein a syringe is inserted into a syringe mating mechanism having a gasket which can facilitate the immediate relief of pressure in the fluid lumen once the pressure on the syringe plunger is released.
