US Patent 12023211 Dexterous dental handpiece with hand and foot actuation

A dental instrument comprises a fluid driven handpiece in fluid communication with a valve; a source of fluid in fluid communication with the valve; and a controller in electrical communication with the valve and an actuator positioned on the handpiece. The actuator is configured to cause the valve to move between a first position in which fluid cannot flow from the source of fluid to the handpiece and a second position in which fluid flows from the source of fluid to the handpiece thereby driving the handpiece. The dental instrument may further comprise a second actuator in communication with the controller. The second actuator is configured to cause the valve to move between the first position in which fluid cannot flow from the source of fluid to the handpiece and the second position in which fluid flows from the source of fluid to the handpiece thereby driving the handpiece.
