Motor assembly for injection control device
First Claim
1. A spring motor mechanism for controlling an operation of an injection control device (ICD) having an ICD body, a positioning guide, a syringe supporting section coupled to the ICD'"'"'s body, and a plunging member that is automatically moved forward as the ICD'"'"'s body is pulled away from the positioning guide, the spring motor mechanism comprising:
- a removable body capable of being fitted to a cavity in the ICD body;
the body housing an axle having wound thereupon a spring; and
a gear coupled to the axle, the gear coupling the plunging member when the spring motor mechanism is inserted into the cavity of the ICD body, wherein the spring generates a torque to the gear to provide a controlled force to the plunging member, enabling the positioning guide to be automatically retracted after operation of the ICD.

Abstract
A spring motor mechanism for use in an injection control device having a metered/controlled injection rate proportional to the rate of withdrawal/injection suitable for cosmetic as well as other applications is described. After the cannula is advanced into an object (person) the cannula is withdrawn to create a tract or tunnel within the targeted area. As the cannula is withdrawn, filler material in the injection control device is uniformly deposited into the tract or tunnel via the automatic metering system. As one feature, the spring motor mechanism automatically retracts the positioning guide that is used in the metering systtem. The spring motor mechanism may be replaceable or customizable, offering the user enhanced safety and convenience of operation for the injection control device.

11. A spring motor mechanism for controlling an operation of an injection control device (ICD) having an ICD body, a positioning guide, a syringe supporting section coupled to the ICD'"'"'s body, and a plunging member that is automatically moved forward as the ICD'"'"'s body is pulled away from the positioning guide, the spring motor mechanism comprising:
-
removable means for housing the spring motor mechanism, the means for housing being capable of being fitted to a cavity in the ICD body; tensioning means for providing a controlled force to an axle coupled to the removable means; and coupling means for translating a rotational motion to a linear motion, being connected to the tensioning means, the coupling means engaging the plunging member when the spring motor mechanism is inserted into the cavity of the ICD body, wherein the tensioning means generates a torque to the coupling means to provide a controlled force to the plunging member, enabling the positioning guide to be automatically retracted after operation of the ICD. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method for operation of an injection control device (ICD) comprising:
-
positioning a positioning guide at a fixed distance from an object; inserting a cannula attached to a syringe coupled to an ICD into the object; withdrawing the cannula with the positioning guide held at the fixed distance, wherein the ICD automatically injects material from the syringe into a track left by the withdrawing cannula at a rate that is consistently proportional to a distance traveled by the ICD from the position of the positioning guide; and retracting the positioning guide automatically back to a body of the ICD. - View Dependent Claims (20)
