Abstract
A device positions and/or orients in the body of a patient, a surgical tool carried by a tool-holder, including a platform capable of being placed on the body of the patient, an orientable carrier, at least one part of which is rigidly connected to the tool-holder, means for guiding the orientable carrier rotationally relative to the platform in two directions of a plane parallel to the platform, at least 2 pneumatic actuators which engage with the orientable carrier such that a variation in pressure of at least one of the pneumatic actuators causes the orientable carrier to rotate in the first direction and/or the second direction, in which the pneumatic actuators are volumes that can deform in a predetermined direction as a function of the internal pressure.
