Abstract
A medical instrument having an aspiration needle and handle device. The handle device controls the force required for a user to activate the needle and provides a higher force to initially activate and a lower force to continue sliding. Grooves at either end of the activation act as locking elements which provide feedback with a "pop" sound at either end of the travel. The handle also supports "one-way" manufacturing of the handle assembly, with an O-ring passing over a larger diameter shaft during initial assembly, thus preventing disassembly.
