The invention relates to a device for minimum incision foot surgery, comprising an envelope (2a) that holds the foot in a specific position and orientation for the surgery. Said device includes interchangeable guides (8) so that the pre-defined region of operation (9a) of the set of surgical instruments is limited. The envelope can be standard (2f) or customized (2f) (2g) (2h), with drainage (23), parts (34) that assist the surgery, parts (36) that assist the soldering of the bones, and parts (38) for fixing to the table, in addition to a sole (40) and an interface (44) for the adjustment of the guide part in terms of position and orientation. In order to facilitate the surgical operation, the device can include sensors, emitters, markers and receptors used to obtain technical data that is then processed by a computer (52a) (52b) providing the surgeon with information on the screen (53a) (53b) and virtual reality or augmented reality simulations (54).
