Abstract: A fluid flow metal sleeve includes a sleeve main body and an elongation portion, which are of a hollow structure as a whole. The sleeve main body is connected to the elongation portion in a threaded manner, and a terminal end of the sleeve main body is connected to an ultrasound scalpel handle and enables an ultrasound scalpel to pass therethrough. The fluid flow metal sleeve can control the direction of fluid flow during incision with the ultrasound scalpel so as to achieve the lubricating and cooling effects on a scalpel head. In addition, due to the use of a metal structure, a user can extend an original holding part from an outer portion of the ultrasound scalpel handle to an outer wall of the metal sleeve as required. The fluid flow metal sleeve also has an adjustable telescopic function so as to be adapted to different application scenarios, and limits the length of extension of the scalpel head so as to limit the depth during incision to improve the safety of surgery.

Abstract: 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.
