Abstract: A minimally invasive surgical device includes a main body, a buffer assembly and a cutter bit. The main body includes an inner tube and an outer tube, wherein the inner tube is disposed in the outer tube. An end of the buffer assembly is connected to the inner tube. The cutter bit is connected to another end of the buffer assembly, wherein the cutter bit has a cutting portion. When the cutting portion is in contact with an object, the buffer assembly is adapted to enable the cutter bit to move relatively to the inner tube to decrease a cutting force between the cutting portion and the object, and is adapted to enable the cutting portion to be tilted with a surface of the object.
