Enhanced dual barrel syringe enclosure with rotational detachment system for simultaneous irrigation and aspiration in endodontic procedures

A method of using a dual barrel syringe assembly, the method comprising:

• obtaining a dual barrel syringe assembly, the dual barrel syringe assembly including:
• a first cover component and a second cover component defining a portion of an exterior of the dual barrel syringe assembly and an interior chamber of the dual barrel syringe assembly;
• a first barrel and a first plunger in fluid communication with the first barrel, the first plunger being movable between a retracted state, relative to the first barrel, and an extended state, relative to the first barrel, the first plunger extending in the interior chamber of the dual barrel syringe assembly when positioned in the retracted state thereof;
• a second barrel and a second plunger in fluid communication with the second barrel, the second plunger being movable between a retracted state, relative to the second barrel, and an extended state, relative to the second barrel, the second plunger extending in the interior chamber of the dual barrel syringe assembly when positioned in the retracted state thereof;
• a tip piece connectable to at least one of the first and second cover components, the tip piece being configured to selectively affix the first and second barrels to the at least one of the first and cover components when said tip piece is connected to the at least one of the first and second cover components, said tip piece fluidly connecting the first and second barrels to an outside of the dual barrel syringe assembly;
• a trigger rotatably coupled to at least one of the first and second cover components;
• and
• a mechanism connecting the trigger to the first and second plungers, the mechanism being configured to move the first and second plungers in an opposing synchronous manner in response to a rotational movement of the trigger relative to at least one of the first and second cover components,
• wherein the first barrel is filled at least partially with a fluid configured to sterilize or clean a root canal of a patient;
• inserting a first needle and a second needle of the tip piece of the dual barrel syringe assembly in a root canal of a patient;
• and
• squeezing the trigger such that the first needle discharges a quantity of the fluid in the root canal and, via the opposing synchronous movement of the first and second plungers, the second plunger creating suction via the second needle such that at least a portion of the discharged quantity of fluid can be conveyed into the second barrel,
• wherein the mechanism includes:
• a central structure having a body rotatably connected to at least one of the first and second cover components;
• a first arm rotatably connected to the first plunger and rotatably connected to the central structure;
• and
• a second arm rotatably connected to the second plunger and rotatably connected to the central structure, the first and second arms being rotatably connected to the central structure at different locations of the central structure,
• wherein the body of the central structure includes an elongated through opening spaced apart from said different locations of the central structure where the first and second arms rotatably connect to the central structure, and
• wherein the trigger includes:
• a first lever portion extending in a first direction from a region of the trigger where the trigger rotatably connects to the at least one of the first and second cover components;
• and
• a second lever portion extending in a second direction from the region of the trigger where the trigger rotatably connects to the at least one of the first and second cover components,
• wherein said second lever portion includes a protrusion extending in the elongated through opening of the body of the central structure,
• the protrusion being slidably coupled to the elongated through opening such that a rotation of the trigger relative to at least one of the first and second cover components is configured to rotate the second lever portion, causing the protrusion to be slid along a length of the elongated through opening, in turn, causing the central structure to be rotated relative to at least one of the first and second cover components, thereby causing the first and second arms to move the first and second plungers in the opposing synchronous manner.
