A fluid dispensing device (10) for delivering a dose of fluid into a surgical site includes a tube (12) with a lumen (22) for receiving the dose of fluid, a housing (14) coupled to the tube, and a flexible plunger (24) at least partially disposed in the housing (14). The fluid dispensing device (10) also includes an actuation device (66, 140) engaging the flexible plunger (24) and a trigger (26) operable to cause the actuation device (66, 140) to move the flexible plunger (24). The actuation device (66, 140) may be toggled between a first operational mode in which movement of the trigger (26) advances the flexible plunger (24) into the lumen (22) and a second operational mode in which movement of the trigger (26) retracts the flexible plunger (24) from the lumen (22). |
