An electrosurgical coagulating and cutting instrument employing pairs of clamping arms having wrist portions proximal to closing ramps and jaws and configured to close at their wrists first, then their distal tips and lastly, their heels. The instrument includes mechanisms for preventing the advancement of a cutting blade when the jaws are not closed. An actuator for closing the jaws includes an actuator handle and a drive head having teeth formed therein and a pawl mounted in the handle for engaging the teeth, these latter structures forming a ratcheting mechanism. Said mechanism is controllably releaseable.
L'invention concerne un instrument électrochirurgical permettant de coaguler et de couper, utilisant des paires de bras de préhension ayant des parties poignet proches de rampes et de mâchoires de fermeture, conçus pour se fermer d'abord au niveau desdits poignets, puis de leurs pointes distales et enfin des talons. Ces instrument comprend des mécanismes qui empêchent l'avancée d'une lame tranchante lorsque les mâchoires ne sont pas fermées. Un actionneur, destiné à fermer les mâchoires, comprend une poignée et une tête d'entraînement possédant des dents, ainsi qu'un cliquet monté au sein de la poignée et servant à entrer en prise avec lesdites dents, ces structures formant un mécanisme d'encliquetage pouvant être déclenché de manière régulée.
