Our Product - The Dispencil
The idea for this device is inspired by a mechanical pencil. With a simple click, it generates precise linear movement, releasing an optimal quantity of gel for glaucoma laser surgery. It is the first discrete dosage dispenser for ViaLase’s FLigHT procedure.
How it Works:
The Ring allows the Fingers to compress.
The Fingers comply to shape of Ring.
The Fingers release Extruder Shaft while exiting the Ring.
The Button Spring returns Fingers upward into its compressed state.
Properties

Materials Used |
|---|---|
| One button click = 160 μL Two button click = 320 μL The device will enable end users to consistently deliver 160 µL of gel on the top of the patient interface (PI) with one click of the button and 320 µL beneath the PI with two clicks. |
The main components of the device (Housing, Tip, Button, Ring, Claw, Extruder Shaft) are 3D-Printed with Polylactic Acid (PLA). The Gel Housing is made of a clear resistant plastic. The device also contains a metal spring, rubber, and sand paper. |
Dimensions
The Dispensil is lightweight for convienience and comfortability. It has a length of 15 cm (5.9 in) and a diameter of 2.3 cm(0.9 in). Its weight is only 32 grams.
Future Work
The next steps for this project involve exploring alternative materials and manufacturing methods, such as injection molding, to facilitate large-scale production of our device. As well, conduct detailed research on eye conditions that may require the application of gel during surgery. This can potentially expand the market for our device.
