ULTRASONIC DEVICE FOR DESTRUCTION AND ASPIRATION OF OCULAR GLOBE TISSUES

摘要

The invention relates to medical devices. The device forming the subject of the invention is of the type comprising an ultrasonic control generator 1 whose output 2 is connected to a magnetostrictive converter. FOR THE TRANSFORMATION OF THE ULTRA-SOUND ELECTRICAL OSCILLATIONS IN MECHANICAL VIBRATION, A HOLLOW NEEDLE 7 OF WHICH THE AXIAL CHANNEL 7 IS CONNECTED BY ONE OF ITS END TO THE MAGNETOSTRICTIVE CONVERTER FOR IT TRANSMIT THE SAID MECHANICAL VIBRATION, THESE ENSURING THE DESTRUCTION AND THE ASPIRATION OF THE PRODUCTS OF DESTRUCTION OF SAID FABRICS, AND WHOSE FREE OPPOSITE END OPERATES ON THE FABRIC TO BE EXTRACTED, AND IS CHARACTERIZED IN THAT THE FREE END OF NEEDLE 7, INTENDED TO ACT ON THE EYE FABRIC TO BE EXTRACTED, IS PROVIDED WITH END WALL 11 COMPRISING A DETACHING HOLE 12, THE DIAMETER OF WHICH IS LESS THAN THE DIAMETER OF THE AXIAL CHANNEL 7 OF THE NEEDLE 7, AND WHICH COMMUNICATES WITH THE CHANNEL. / P P THE INVENTION MAY BE USED WITH THE MORE SUCCESS FOR THE EXTRACTION OF TISSUES WITH CATARACT. / P
