STOMATOLOGICAL TIP Russian patent published in 2006 - IPC A61C1/12 

FIELD: dentistry.

SUBSTANCE: stomatological tip can be used in turbo-drive boring machines for drilling or milling. It can be also used in other branches of medicine and engineering where compact devices are needed being capable of providing operation of cutting tool under specific conditions. Stomatological tip has case with channel for feeding gas and head provided with aid for mounting dental instrument, turbine and curved intermediate channel for feeding gas to turbine. Head is mounted for rotation and fixation in jack at end of case. Curved intermediate channel for feeding gas to turbine has at least one working output. Longitudinal axis of aid for mounting dental instrument is oriented at obtuse or acute angle to plane of curved intermediate channel for feeding gas. Intermediate channel is made in form of at least two opposite disposed grooves, one of which grooves is placed onto internal surface of jack, and the other one is placed onto internal surface of head. At least one working output of intermediate channel is made in form of nozzle or opening having longitudinal axes. Longitudinal axes are disposed in plane which coincides with plane of curved intermediate gas-feeding channel or it doesn't' coincide with plane of the curved intermediate channel for feeding gas to turbine.

EFFECT: improved efficiency of treatment; improved interaction with treated tissue of dental instrument.
