Drill for lateral sinus graft surgical operation

摘要

start drilling for sinus elevation procedures . Drills for sinus elevation procedures of the present invention, the drill rod ; And a cutter for cutting the maxillary alveolar bone during drilling , when cutting the bone to the cutter to cool the heat generated by the friction of the bone and a cutter provided with a brine supply hole to supply the saline solution to the inside of the cutter , drill rod which is characterized in that comprises a cloth that is provided on one side of the study . According to the present invention , the life of the sinus elevation is to be smoothly cut the bone to form a window (window) on the side of the maxillary sinus , and the alveolar bone and the drill during the cutting operation to cool down the heat generated by the friction of the cutter can be obtained which is capable of preventing the shortening effect . ;
