Abstract
A medical ultrasonic scalpel includes a fluid flow sleeve 100 and a blade shank 200. The fluid flow sleeve includes a sleeve body 101 and a first projection 102. The sleeve body is provided with mounting cavities 111 that penetrate both ends thereof, and the first projection is located on the inner side wall of the sleeve body. The blade shank penetrates the mounting cavities and is rotatably connected to the fluid flow sleeve, and the blade shank and fluid flow sleeve are movable in the extending direction X, and a second projection 202 is provided on the outer side wall of the blade shank. When the fluid flow sleeve rotates in a first rotational direction, the first projection and the second projection are offset from each other so that the fluid flow sleeve is movable in the extending direction X. When the fluid flow sleeve rotates in a second rotational direction opposite to the first rotational direction, the first projection abuts against the second projection so as to drive the blade shank to rotate in the second rotational direction.
