A surgical clamp (10) combination includes a clamp movable between a free state and operable state, the clamp including a pair of jaws (36, 38) which can be operated to occlude a body conduit (32). A clamp applier (12) is adapted to releasably engage the clamp in the free state and to operate the clamp in the operable state to close the jaws. The applier has a housing disposed at a proximal end and a tube (23) extending distally and configured to receive the clamp in the operable state. A shaft (58) is disposed within the tube and movable between an extended position to engage the clamp in the free state and a retracted position to releasably hold the clamp in the operable state. With the clamp in the operable state, the shaft is rotatable by operation of a handle and aladdin screw (47), to alternatively rotate in opposite directions to open and close the jaws of the clamp.

Un combiné à clamp chirurgical comporte un clamp pouvant passer d'un état libre à un état fonctionnel et comportant des mâchoires qui permettent d'obturer un conduit corporel. Un applicateur de clamp est prévu pour entrer en prise avec ce clamp à l'état libre et pour l'utilisation du clamp à l'état fonctionnel pour fermer les mâchoires. Cet applicateur comporte un logement placé à l'extrémité proximale et un tube distal configuré pour recevoir le clamp à l'état fonctionnel. Un axe, disposé dans le tube, est mobile entre une position déployée, pour entrer en prise avec le clamp à l'état libre et une position rétractée pour maintenir ce clamp, de façon réversible, à l'état fonctionnel, dans lequel l'axe peut tourner, grâce au fonctionnement de la poignée et d'une vis de transformation de mouvement, dans un sens puis dans l'autre pour ouvrir et fermer les mâchoires du clamp.
