Abstract: The present application discloses a body support device for surgery with a dynamic support for the torso. This device stimulates the adoption of a more natural posture and provides the dissipation of the load placed on the bone and muscle structures in the spinal column through the combination of the torso support (1) to the posterior support (13). The posterior support (13) consists of the systematization of the human vertebral column, comprising a set of segments (13?) chained and aligned by the passage of an elastic medium (14) therein, controlled by the user's action. Thus, this technology allows for minimizing surgeon's physical fatigue resulting from a prolonged posture in surgery.
