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.

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.

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.

Disclosed is an ultrasonic scalpel bit, comprising a bit tip (), a bit bar () and a bit body (), one end of the bit bar () being connected to the bit tip (), and the other end of the bit bar () being connected to the bit body (), wherein a main body of the bit tip () is of a flat sheet structure, an upper and a lower face of which respectively form an upper bit ridge () and a lower bit ridge () of the bit tip (); a protrusion () is formed at a front end of the upper bit ridge (); the upper bit ridge () has a thickness greater than that of the flat sheet structure and that of the lower bit ridge (); and the protrusion () is smooth and free of edges.
