Abstract
The proposed invention relates to medicine, namely to stomatology. The essence of the invention consists in that a confidence channel is formed in metal or plastic handle and rod, where the channel is cone-shaped in the edge section similar to the rod, and a coupling rod is made rigidly in the handle, which moves back and forth in the handle and in the rod, and by a circle of rod edge section the longitudinal slits are formed, which are connected with a confidence channel, and divided scale is applied on external surface of the coupling rod and the rod. The technical result is provided by the fact that owing projection movement under pressure of the coupling rod outside the cylindrical rod circle it is possible to measure channel diameter, and owing to stop-sleeve to the projection it is possible to measure a length of formed channel.
