摘要： 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.

摘要： An ultrasonic bone scalpel bit includes a scalpel bit end portion located at a distal end of the scalpel bit, the scalpel bit end portion being formed to have a flat shape and provided with a cutting portion. The cutting portion includes a distal end portion, a first side portion and a second side portion, the first side portion and the second side portion being symmetrically arranged relative to a longitudinal axis of the scalpel bit end portion in a width direction of the scalpel bit end portion. The cutting portion further includes a plurality of protrusions formed near the distal end portion, the plurality of protrusions projecting outward from the first side portion and the second side portion symmetrically relative to the longitudinal axis in the width direction of the scalpel bit end portion.

摘要： The invention discloses a probe and a method of manufacturing the same. The probe has a long cylindrical shape and includes a probe head (1), a probe body (2) at the rear of the probe head (1), and a probe tail (3) at a rear end of the probe body (2). The probe has a three-layer composite structure. The probe tail is a three-layer composite structure. The probe of the invention is used to detect a body tissue, and according to different electrical signals fed back by different body tissues, a type of the body tissue being detected by the probe can be known, thereby avoiding a medical accident in which a spinal cord or nerve is injured by a screw intruded into a vertebral foramen. The probe of the invention is simple in structure, convenient for use, easy in operation, of high reliability, high surgical safety and high success rate of surgery.

摘要： 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.
