Mist Nozzle Removal Tool

Convergent Dental · Mechanical Engineering Intern · Concept through printed prototype

A hand tool that makes swapping the mist nozzle on a dental laser handpiece quick, so it no longer needs a service visit.

The problem

The mist nozzle on the Contra handpiece is tiny and hard to remove by hand, so replacing it meant a field service visit.

Slots guide the tool onto the nozzle, lock tabs engage it with a turn, and a pull removes it.

I went from concepts to a down-select, then CAD and 3D-printed prototypes that I refined for fit.

Quick, tool-assisted nozzle swaps and fewer service visits.
