An ultrasonic osteotome bit, comprising a bit body (), a bit bar () and a bit tip (). One end of the bit bar () is connected to the bit tip (), and the other end of the bit bar () is connected to the bit body (). The bit tip () is of a prism or substantially prism structure with the cross section of a polygonal structure, and the bit tip () has at least two cutting faces of different cutting widths. The bit is provided with a liquid flow hole (), and the bit tip () is provided with a knurled structure that extends from a foremost end face of the bit tip () towards the bit bar () to form a file-type bit. The ultrasonic osteotome bit not only meets the requirement of a surgeon for the accuracy of bone cutting width, but also saves the time required to replace bits of different widths, thereby improving the surgical efficiency.

Ultrasonic osteotome bit

A tool bit for an ultrasonic osteotome includes a bit body, an arbor fixed to the bit body, and a flat end portion fixed to the arbor. A toothed edge extends linearly along a length direction of an end portion of the tool bit, and recesses are distributed evenly on the toothed edge to form teeth spaced apart from each other. The toothed edge extends linearly along a length direction, and the cutting edges of teeth are distributed linearly, e.g., instead of having a sharp structure, thus will not scrape and hurt other tissues during cutting. Since the thickness of the cutting edge is the same as that of the back edge, when cutting bone tissues, the incision is wide, thus the end portion is not easy to be clamped by bone tissue, which effectively prevents the end portion from breaking and reduces occurrence chances of surgery accidents.

Tool bit for ultrasonic osteotome and ultrasonic osteotome having the same

A tool bit () of an ultrasonic osteotome includes: an arbor (); and an end portion () of the tool bit connected to a front end of the arbor (). The end portion () of the tool bit has a spoon-like shape and has a toothed front edge. An ultrasonic osteotome including the tool bit is also provided.

Tool bit of ultrasonic osteotome and ultrasonic osteotome including the same

Disclosed are a tool bit of an ultrasonic osteotome and an ultrasonic osteotome including the same, the tool bit comprising: an arbour (); and an end portion () of the tool bit connected to a front end of arbour (), wherein the end portion () of the tool bit has a hook-like shape and includes a hook tip (), a hook handle (), as well as a hook-shaped interconnecting piece () which is interconnected between the hook tip () and the hook handle (). The hook handle () is connected with the arbour (), and the inner side edge of the hook-shaped interconnecting piece () is tooth-like. With this ultrasonic osteotome, the cutting efficiency is high and surgery time is short, therefore the labour intensity of medical workers is decreased. Moreover, accurate positioning can be realized in cutting process with no skidding, so the chance of success of surgery can be improved.
