An insufflation pump is provided for single handed actuation for inflation of dilatation balloons or other inflatable devices employed during medical procedures. The insufflation pump includes a pump body having a first end and a second end. The first end is provided with a syringe mechanism and the second end is provided with an actuation mechanism. The syringe mechanism and the actuation mechanism are linked by a pivoting mechanical linkage member facilitating the transfer of power from the actuation mechanism to the syringe mechanism. The actuation mechanism includes an actuator pivotally secured adjacent the second end of the pump body. The linkage member includes a first end and a second end, the first end of which is pivotally connected to the second end of the actuator, the second end of the linkage member is pivotally secured to the plunger of the syringe mechanism.
