Surgical stapler, applicable to open or laparoscopic surgeries, being of the type that are constituted from a device as a scissor, or swinging closure, involving two arms (1-2) of gripping and pressing , articulated on an axis (3) and topped by respective jaws (4-5), so that in one of said jaws (5) a series of conformations (6) is established internally, intended to plastically deform the staples (7) that they are disposed on the complementary jaw (4), staples (7) initially of "U" configuration, which are disposed on molars (9) displaceable vertically by the effect of a cam (10) in which a push rod is terminated (11) longitudinally displaceable in the mandible (4), characterized because between the axis of articulation (3) of the two jaws (4-5) and the initial end in which the conformations (6) and the molars are arranged vertically movable (9) on which are available the staples (7), a spacing (12) is defined between the axis and the principle of the stapling of the anastomosis that allows to preserve the part of the intestine included in said space, from which the actual anastomosis is performed.
