Actuator and device for synchronized injection and aspiration

A method for enabling single-hand operation of standard-size syringes for synchronized injection and aspiration, comprising:

• placing first and second standard-size syringes in mounts of a housing fitted to hold standard-size syringes, the housing having an anchor for supporting a distally disposed curve portion of a flexible connector and movement of said flexible connector, while a first plunger in the first standard-size syringe is pressed to inject fluid from said first standard-size syringe and the second standard-size syringe automatically and simultaneously aspirates fluid, enables single-hand operation;
• distally displacing a first plunger of the first standard-size syringe to inject fluid from said first standard-size syringe;
• distally displacing a first rod, said first 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 the flexible connector which is mechanically attached to a distal end of said first rod;
• proximally displacing a second end of said flexible connector which is mechanically attached to a distal end of a second rod;
• proximally displacing the second rod, said second rod having a length equal to an inner length between a head of a second plunger of the 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 aspirate fluid from said second standard-size syringe.

A method of using a device for enabling single-hand operation of standard-size syringes for synchronized injection and aspiration, comprising:

• inserting a first standard-size syringe and a second standard-size syringe into syringe mounts of a housing of said device, the housing having an anchor for supporting a distally disposed curve portion of a flexible connector and movement of said flexible connector, while a first plunger in the first standard-size syringe is pressed to inject fluid from said first standard-size syringe and the second standard-size syringe automatically and simultaneously aspirates fluid, enables simile-hand operation;
• positioning a first rod adjacent to the 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 the 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.
