A long bone fracture resetting robot comprises an engine base (1) and multiple sets of electro-hydraulic drivers (4). A support (5) capable of moving up and down is slidably connected on the engine base (1), and a six-degree-of-freedom parallel robot (2) is disposed on the support (5). The six-degree-of-freedom parallel robot (2) comprises multiple first hydraulic cylinders (6). The number of the first hydraulic cylinders (6) is the same as the number of the electro-hydraulic drivers (4), and one-to-one correspondence exists between the multiple first hydraulic cylinders (6) and the multiple electro-hydraulic drivers (4) and they are in a driving connection. The long bone fracture resetting robot can plan a movement track of the six-degree-of-freedom parallel robot (2) according to a CT scan before a surgery, and precisely control movement of a wounded limb through the six-degree-of-freedom parallel robot (2), so as to complete resetting of the wounded limb. By using the long bone fracture resetting robot to perform a resetting surgery, only one CT scan is needed； therefore, the quantity of radiation on a doctor and a patient is reduced. In addition, the movement of a wounded limb is controlled through the six-degree-of-freedom parallel robot (2)； therefore, the resetting precision is high, and the surgical stability is good.Un robot de réduction de fractures touchant des os longs comprend une base motrice (1) et de multiples ensembles de dispositifs d'entraînement électro-hydrauliques (4). Un support (5) apte à se déplacer vers le haut et vers le bas, est relié coulissant à la base motrice (1), et un robot parallèle à six degrés de liberté (2) est disposé sur le support (5). Le robot parallèle à six degrés de liberté (2) comprend de multiples premiers cylindres hydrauliques (6). Le nombre de premiers cylindres hydrauliques (6) est identique au nombre de dispositifs d'entraînement électro-hydrauliques (4), et une correspondance biunivoque existe entre les multiples
