Abstract[English]
The present disclosure generally relates to surgical instruments for ophthalmic surgical procedures, and more specifically, surgical instruments that are capable of providing femtosecond laser pulses. In some aspects, a surgical instrument includes a body and a power amplifier disposed within the body. The power amplifier is configured to receive laser pulses from a laser source external to the body, and to deliver amplified laser pulses to an optical fiber extending toward a distal end of the body. The surgical instrument further includes an optical element disposed near the distal end. The optical element is configured to focus the amplified laser pulses.[French]
La présente divulgation concerne de manière générale des instruments chirurgicaux destinés à être utilisés dans des interventions chirurgicales ophtalmiques, et plus spécifiquement, des instruments chirurgicaux qui sont capables de fournir des impulsions laser femtosecondes. Selon certains aspects, un instrument chirurgical comprend un corps et un amplificateur de puissance disposé à l'intérieur du corps. L'amplificateur de puissance est configuré pour recevoir des impulsions laser provenant d'une source laser externe au corps, et pour délivrer des impulsions laser amplifiées à une fibre optique s'étendant vers une extrémité distale du corps. L'instrument chirurgical comprend en outre un élément optique disposé à proximité de l'extrémité distale. L'élément optique est configuré pour focaliser les impulsions laser amplifiées.
