WHAT IS CLAIMED IS:

1. An actuator for synchronized injection and aspiration, comprising:

a first rod, having a length equal to an inner length between a head of a first plunger of a first standard- size syringe and a seal of said first plunger, and having a width smaller than a gap created between said first plunger and a barrel of said first standard-size syringe;

a second rod, having a length equal to an inner length between a head of a second plunger of a second standard-size syringe and a seal of said second plunger, and having a width smaller than a gap created between said second plunger and a barrel of said second standard- size syringe;

a flexible connector mechanically attached to a distal end of said first rod at a first end and to a distal end of said second rod at a second end.

2. The actuator of claim 1, further comprising:

an anchor for said flexible connector, supporting a distally disposed curve portion of said flexible connector and movement of said flexible connector.

3. The actuator of claim 1, wherein:

said first rod includes a first holder at a proximal end, said first holder is detachably mechanically coupled to said first plunger; and

said second rod includes a second holder at a proximal end, said second holder is detachably mechanically coupled to said second plunger.

4. The actuator of claim 1, wherein said first rod and said second rod are tubes, and said flexible connector is a sting inserted into said tubes.

5. The actuator of claim 1, further comprising:

a one-way mechanism which allows said flexible connector to move only in one direction.

6. The actuator of claim 1, wherein said first rod and said second rod are having a profile with a 90 degrees corner, to fit within an X-shaped profile of plungers.

7. A device comprising the actuator of claim 1, further comprising:

a housing having syringe mounts for holding said first standard-size syringe and said second standard-size syringe.

8. A device comprising the actuator of claim 1, further comprising:

a grip; and

a trigger coupled to a pushing rod which pushes said first plunger.

9. A method for synchronized injection and aspiration, comprising:

distally displacing a first plunger of a first standard-size syringe to inject fluid from said first standard-size syringe;

distally displacing a first rod, said rod having a length equal to an inner length between a head of said first plunger and a seal of said first plunger, and having a width smaller than a gap created between said first plunger and a barrel of said first standard-size syringe;

distally displacing a first end of a flexible connector which is mechanically attached to a distal end of said first rod is distally displaced;

proximally displacing a second end of said flexible connector which is mechanically attached to a distal end of a second rod;

proximally displacing a second rod, said second rod having a length equal to an inner length between a head of a second plunger of a second standard-size syringe and a seal of said second plunger, and having a width smaller than a gap created between said second plunger and a barrel of said second standard-size syringe; and

proximally displacing said second plunger to aspire fluid from said second standard-size syringe.

10. A method of using a device for synchronized injection and aspiration, comprising: inserting a first standard-size syringe and a second standard-size syringe into syringe mounts of a hosing of said device;

positioning a first rod adjacent to a first plunger of said first standard-size syringe, so said first rod is held by a head of said first plunger at a proximal end and by a seal of said first plunger at a distal end;

positioning a second rod adjacent to a second plunger of said second standard-size syringe, so said second rod is held by a head of said second plunger at a proximal end and by a seal of said second plunger at a distal end; wherein a flexible connector is mechanically attached to a distal end of said first rod at a first end and to a distal end of said second rod at a second end; and

pushing said first plunger to inject fluid from said first standard-size syringe, while aspirating fluid from said second standard-size syringe.
