摘要：
Provided is a spreading blade (1), which comprises a first clamping portion (11), a second clamping portion (12), a fixing portion (13), a blocking panel (14) and a hook edge (15). An axial flat section (111) is provided at a side of the first clamping portion (11). An end of the second clamping portion (12) is connected to the first clamping portion (11), the other end is fixed on the fixing portion (13), and a protruding positioning block (123) is provided on a side wall of the second clamping portion (12). An end of the blocking panel (14) is connected to the fixing portion (13), and the other end is provided with a hook edge (15) inclined outward, the fixing portion (13) and the hook edge (15) both being disposed on the same side of the blocking panel (14). Further provided are a unidirectional spreading device and a bidirectional spreading device using the described spreading blade (1). The spreading blade (1) is provided with two clamping and fixing structures, which may be clampingly connected to different devices by using different manners of mounting. At the same time, the unidirectional spreading device and the bidirectional spreading device use the same type of spreading blade (1), reducing the equipment used in surgery, and reducing costs； in addition, the manners of connection are simple clamping and fixing manners, while the devices have simple structures and are easy to disassemble and replace.L'invention concerne une lame d'étalement (1), qui comprend une première partie serrage (11), une seconde partie serrage (12), une partie fixation (13), un panneau de blocage (14) et un bord de crochet (15).
