DISPENSING MATERIAL FROM A DENTAL HANDPIECE

摘要

Devices and methods for dispensing material from a dental handpiece. In one example, the method includes receiving an input that indicates that an amount of the material is to be dispensed from the container of the dental handpiece. The method also includes rotating an electric motor to rotate an imbalanced mass to vibrate a vibration transmission element that vibrates the material in the container. The method also includes dispensing the amount of the material from the container with a piston based on the input.

主权项

1. A dental handpiece comprising:
a power source; a controller electrically connected to the power source; a vibration generator configured to generate vibrations by rotating an imbalanced mass, the vibration generator having an electric motor electrically connected to the controller; a linear electromagnetic actuator electrically connected to the controller; a magnet; a container configured to hold a material and having a piston; a vibration transmission element configured to transmit vibrations caused by rotation of the imbalanced mass to the container; and a tip, wherein the linear electromagnetic actuator is configured to move the piston of the container to dispense the material through the tip while the container is vibrated by the vibration transmission element.
