CA 2173997

The present invention is embodied in a surgical apparatus that can be used in laparoscopic surgical procedures. In particular, the apparatus includes a universal actuating handle for use with different end effectors and that can convert a single handle motion into two separate and independent actuator motions required for actuating two separate actuating members. The handle also includes a collar that facilitates the connection and disconnection of the end effector to and from the handle in a single translational snap-on or snap-off motion. The handle also has a ratchet and pawl mechanism to provide improved control over actuation.

La présente invention concerne un instrument chirurgical utilisable pour les interventions chirurgicales sous coelioscopie. En l'occurrence, l'instrument, qui comporte une poignée manipulatrice universelle utilisable avec différents accessoires terminaux, peut, à partir d'un simple mouvement de poignée, produire les deux mouvements séparés et indépendants d'actionneurs nécessaires à l'actionnement de deux éléments actionneurs séparés. La poignée comporte également une virole facilitant le montage et le démontage des accessoires terminaux sur la poignée par un simple mouvement d'encliquetage et de désencliquetage. La poignée comporte également un mécanisme de roue à rochet assurant une meilleure maîtrise de la manipulation.
