1. A syringe dispenser for expressing an irrigant from a syringe which has a plunger movably positioned inside a barrel, the syringe dispenser comprising:
an upper housing and a lower housing connected to the upper housing, the upper and lower housings sequentially arranged with respect to a syringe plunger orientation;
a syringe mounting part disposed within the lower housing and configured to receive the barrel so that the syringe is mounted on the syringe mounting part;
a slider disposed within the lower housing, the slider having a plunger receiving portion configured to receive the plunger when the syringe is mounted on the syringe mounting part, and
a motor coupling disposed within the upper housing, the upper housing having friction fit bearings and a compression spring, wherein the motor coupling is configured to engage a motor and to transfer an output of the motor to a threaded screw,
wherein, the slider is connected to (i) one or more guide rods which are configured to confine a movement of the slider to a predetermined path and to (ii) said threaded screw which is configured to be operated by the motor coupling such that the slider moves forwards and backwards and creates a corresponding forwards and backwards movement of the plunger, wherein the forwards movement of the plunger expresses the irrigant from the syringe.
