Abstract
A one-handed, self-contained, light-weight syringe for use in applying suction during a surgical operation includes a standardized syringe mounted into a longitudinally cut tube with a wheel attached at a right angle to the tube axis. The surgeon-operator, by turning this wheel with his fingers, may operate the syringe and control the amount of suction. The wheel is fastened to a pinion gear which rotates on a fixed shaft causing a rack and syringe plunger to move relative to the syringe barrel. This device allows the syringe barrel to move very smoothly and also enables the surgeon-operator complete freedom of one hand.
