Abstract[English]
The present disclosure generally relates to surgical instruments having variable stiffness, and more particularly, surgical instruments having variable stiffness for ophthalmic surgical procedures. In certain embodiments, a surgical instrument includes a base unit, a probe, a stiffener, and an actuation mechanism. The stiffener is formed of a hollow tubular member substantially surrounding at least a portion of a length of the probe. The actuation mechanism is configured to actuate the stiffener along the length of the probe and adjust the stiffness of the probe, thus providing a user better control of the surgical instrument. The actuation mechanism includes a stiffener biasing device configured to apply a first biasing force against the stiffener in the distal direction and, in some embodiments, a control member configured to lock the stiffener in a position along the length of the probe.[French]
La présente divulgation concerne de manière générale des instruments chirurgicaux de rigidité variable, et plus particulièrement des instruments chirurgicaux de rigidité variable destinés à des interventions chirurgicales ophtalmiques. Dans certains modes de réalisation, un instrument chirurgical comprend une unité de base, une sonde, un raidisseur et un mécanisme d'actionnement. Le raidisseur est formé d'un élément tubulaire creux entourant sensiblement au moins une partie d'une longueur de la sonde. Le mécanisme d'actionnement est configuré pour actionner le raidisseur dans le sens de la longueur de la sonde et ajuster la rigidité de la sonde, ce qui permet d'obtenir un meilleur contrôle de l'instrument chirurgical par l'utilisateur. Le mécanisme d'actionnement comprend un dispositif de sollicitation de raidisseur configuré pour appliquer une première force de sollicitation contre le raidisseur dans la direction distale et, dans certains modes de réalisation, un élément de commande configuré pour verrouiller le raidisseur dans une position le long de la longueur de la sonde.
