The syringe includes a body portion having an interior barrel chamber. The chamber has a fill port and discharge port. An injection needle is fluidly connected to the discharge port in use. The syringe includes a handle, having one portion that is moveable. As shown in figure 2, the trigger is the rearward most portion of the handle. Slidable in the barrel chamber is a plunger shaft, having a plunger on its terminal end. The trigger is operationally connected to the plunger shaft, so that movement or activation of the trigger results in a corresponding movement of the plunger shaft. As shown, the trigger is pivotally connected to the rear of the plunger shaft. Connected to the syringe is a fluid line, and a communications cable, which can include a power lead and lines for communication between the syringe and computers.
