Injection delivery system
First Claim
1. A neurosurgery injection delivery system for automatically injecting fluid into an injection site, comprising:
- at least one support element;
a carriage moveably mounted to the at least one support element so that the carriage can move linearly relative to the at least one support element;
a motorized carriage actuator operable to cause incremental linear movement of the carriage relative to the at least one support element;
the carriage having a support structure adapted for removably receiving and carrying a syringe assembly for movement with the carriage;
a motorized plunger actuator carried by the carriage so as to move with the carriage, the plunger actuator adapted to be operably coupled to a syringe plunger for causing incremental linear movement thereof within a syringe barrel; and
a motorized rotation actuator carried by the carriage and operable for causing incremental rotation of a syringe cannula relative to the carriage without causing linear movement of the cannula;
wherein the carriage actuator, the plunger actuator and the rotation actuator are co-operable to deliver fluid with;
delivery accuracy;
about +/−
0.1 microliters (100 nanoliters);
volume feedback accuracy;
about 50 nanoliters;
position accuracy;
about 50 micrometers; and
position feedback accuracy;
about 50 nanometers.

Abstract
An injection delivery system for automatically injecting fluid into an injection site includes at least one support element and a carriage moveably mounted to the at least one support element so that the carriage can move linearly relative thereto. The carriage has a support structure for removably receiving and carrying a syringe assembly for movement with the carriage, and a carriage actuator is operable to cause such linear movement of the carriage. A plunger actuator is carried by the carriage so as to move with the carriage, and is adapted to be operably coupled to a syringe plunger for causing linear movement of the syringe plunger within a syringe barrel. The carriage actuator and plunger actuator include respective inputs for receiving movement instructions, and may be coupled to an electronic controller that provides such instructions.
