The ultrasonic osteotom cutter head and the ultrasonic osteotom equipped with the same

摘要

The present invention comprises a cutter body 1 connected to an ultrasonic device, a cutter arbor 2 fixed to the cutter body 1 and a head end 3 of a flat shape fixed to the cutter arbor 2, Wherein the head end (3) comprises a cutter edge (4) which extends linearly along the length of the head end (3) and forms a cutter tooth (6) Wherein a plurality of concave recesses (5) are arranged at equal intervals on the cutter edge (4). In the present invention, the cutter edge of the head end extends linearly in the lengthwise direction of the head end portion so that the blade of the cutter is linearly distributed, but the cutting edge is not a pointed tooth structure so that other tissue structures are not damaged at the time of incision, The thickness of the cutter back edge is set to be the same, and when the bone tissue is cut, the incision site is widened so that the end of the head is not caught by the bone tissue, thereby preventing breakage of the end of the head.
