ABSTRACT:
A precision injection system and method for intralignmental anesthesia and the like having a syringe with a tubular handle portion to which are removably connectable individually tubular headpieces as a longitudinal extension thereof. The headpieces receive a carpule cartridge with semi-solid contents therein or with liquid injection contents monitored during injections through elongate windows on opposite sides of the headpieces. Provision is also made for injection of known composite materials the viscosity of which cannot be determined by standard viscosity measurement methods. A dosing plunger housed in the tubular handle portion in a retracted start position is activated by a servo-dosing lever and advances incrementally axially into a mounted headpiece for delivery of metered quantities of the contents of the carpule cartridge each time the servo-dosing lever is actuated. Provision is made for semiautomatic resetting of the dosing plunger to a retracted start position by depressing a resetting key and raising the syringe to a generally vertically raised position. The dosing plunger has a rack thereon activated by a ratchet cooperative with the servo-dosing lever so that a reduction in the normal pressure applied to the servo-dosing lever is effected in making the injections.
