Composite Extraction Pen
First Claim
1. A dental composite extraction pen comprising:
- a housing;
a carpule tip conformed for the retention therein of a carpule of flowable, extractable material,a tactile feed switch affixed to said housing;
a power source therein said housing;
a variable speed linear actuator assembly with an extendable ram, said linear actuator assembly therein said housing and operatively connected to said power source for the extension of said ram by actuation of said tactile switch.

Abstract
A lightweight, small footprint, composite extraction pen, for the delivery of dental filling composite from commercially available composite filled carpules. An electric linear actuator is housed in a slender, pen-like housing configured to accept, constrain and allow the rotational positioning of commercially available composite filled carpules. The carpules are contained within an adaptor that connects to the body of the pen. The linear actuator extends and retracts a piston through a bore in the carpule so as to exert pressure on the composite contained therein. The pen provides precise composite delivery while maintaining a highly visible dental environment.
