An apparatus to automatically position and operate surgical instruments, particularly for refractive keratic surgery, particularly lamellar refractive surgery, comprising means (1) for correctly positionning in correspondence with the operating cot; means (2) for verticlaly raising all the apparatus; a horizontal guide (3); a first support member (4) slideably arranged on said horizontal guide (3), a horizontal linear actuator (5); which determines the slide in both directions of said support member (4) on the horizontal guide (3); a vertical guide (6), integral with said first support member (4), at right angles to the horizontal guide (3); a second support member (7), slideable in both directions on said vertical guide (6) by means of a first vertical linear actuator (8); a member for operating and supporting (10, 13) the surgical instrument (9), borne by the second support member (7); a horizontal plane (11) integral with said support member (7) and endowed with a second vertical linear actuator (12) which allows its raising and lowering in an autonomous manner, and an arm (15), integral with said means for the positioning (1) and the vertical raising (2) and bearing, at its free end, a member (16) for correctly positioning of the portion which it is operated upon.
Appareil de positionnement et de mise en oeuvre automatiques pour instruments chirurgicaux, notamment en kératomileusis réfractaire, et plus particulièrement en kératomileusis lamellaire. L'appareil comporte un dispositif (1) assurant le positionnement correct par rapport à la zone d'intervention; un dispositif (2) servant à déplacer l'ensemble de l'appareil dans le sens vertical; un dispositif de guidage horizontal (3); un premier élément porteur (4) monté coulissant sur ledit dispositif de guidage horizontal (3); un actuateur linéaire horizontal (5) déterminant le coulissement dans les deux sens dudit élément porteur (4) sur le dispositif de guidage horizontal (3); un dispositif de guidage vertical (6) solidaire dudit premier élément porteur (4) et formant un angle droit avec le dispositif de guidage horizontal (3); un second élément porteur (7) monté coulissant dans les deux sens sur ledit dispositif de guidage vertical (6) par l'intermédiaire d'un premier actuateur linéaire vertical (8); un organe destiné à commander et à porter (10, 13) l'instrument chirurgical (9) et porté par ledit second élément porteur (7); un plateau horizontal (11) solidaire dudit élément porteur (7) et doté d'un second actuateur linéaire vertical (12) lui permettant de monter et de descendre de manière autonome; ainsi qu'un bras (15) solidaire des dispositifs de positionnement (1) et de déplacement vertical (2), et portant au niveau de son extrémité libre un élément (16) de positionnement correct de la partie subissant l'intervention.
