摘要:
In some examples, a medical dispensing device includes a housing and a trigger. A first engager of the device is configured to move axially as the trigger pivots. As the first engager moves, it engages a rod. A maximum proximal position of the rod is defined by a stop. A spring presses the first engager into the trigger such that either the trigger or the first engager rests against a stop limiting rotation of the trigger. A second engager moves axially as the trigger pivots. At the actuated position the second engager, defined by a stop, the second engager limits proximal movement of the rod. An assembly transfers movement of the trigger to the second engager after the trigger has pivoted a threshold amount. A member of the assembly distally moves the second engager. Until it is at the actuated position, the second engager enables the rod to proximally move.
