Methods of treatment using a syringe extrusion accessory

A method of treatment comprising:

• providing a conventional syringe having a medicinal fluid therein for administering to a patient, the conventional syringe comprising a cylindrical body, a flange portion extending radially outwardly from the cylindrical body at a distal portion thereof, and a plunger reciprocally disposed within the cylindrical body;
• coupling an attachment portion of an extrusion accessory to the flange portion of the syringe, the extrusion accessory having a handle hingedly coupled to the attachment portion and a pawl having first and second ends, the pawl being hingedly and rotatably coupled relative to the handle at a first position at the first end and via a pawl-coupling, at a second position between the first and second ends;
• applying a force to translate the handle in a direction that is substantially perpendicular relative to a longitudinal axis of the syringe to cause axial movement of the second end of the pawl, wherein the second end of the pawl is engaged with the plunger of the syringe and axial movement of the second end of the pawl drives the plunger forward to extrude the medicinal fluid from the cylindrical body of the syringe;
• and
• permitting the pawl and the handle to be repositioned by foreshortening of the pawl-coupling between the pawl and the handle such that the pawl is pulled towards the handle.
