An ultrasonic osteotome bit, comprising a bit bar (), a bit body (), and a bit grinding portion () located at a front end of the ultrasonic osteotome bit. The bit grinding portion () is in the shape of a triangular pyramid, the bottom face of the triangular pyramid is the rear end of the bit grinding portion (), and the tip of the triangular pyramid directly facing the bottom face is the front end of the bit grinding portion (). One end of the bit bar () is connected to the rear end of the bit grinding portion (), and the other end of the bit bar () is connected to the bit body (). Two of the three lateral pyramidal faces of the triangular pyramid are respectively used as a first grinding face (A) and a second grinding face (B). By means of the ultrasonic osteotome bit, a normal bone-grinding operation can be completed, and since the front end thereof is small in area, the grinding speed is high. In addition, owing to the design in which the front end is small while the rear end is large, a good visual field can be provided for a surgeon. Moreover, with the unique full V-shaped structures design, the surgeon can guarantee that bone grooves at a hinge side after grinding form fully closed V-shaped grooves at any operating angle, thereby reducing the area of an incision window, facilitating the use by a surgeon and improving the surgical efficiency.

A minimally invasive ultrasonic osteotome head and a minimally invasive ultrasonic powered system for bone; the minimally invasive ultrasonic osteotome head comprises an osteotome rod () and a head end (), the head end () being located at a front end of the osteotome rod(), and the head end () being bent laterally at a certain angle, wherein knurled teeth or skewed teeth are provided on the bent portion. By means of bending the head end (), bone tissue around the transforaminal endoscope may be removed. Therefore, a surgeon may, as much as possible, have more operation space under the limited endoscope channel, thereby increasing bone removal efficiency.
