In general the ultrasonic probe for improved fragmentation is comprised of a longitudinal shank (11) having a proximal end (12), a distal end (13), and a shaft (14). The shaft joins the proximal end, and the distal end. The proximal end of the longitudinal shank has a connector (15) for connecting the longitudinal shank to a source of ultrasonic vibrational energy. The distal end of the longitudinal shank may have a blunt or bullet nosed tip (16). The shaft has one or more grooves (17) near the tip which circumscribe the shaft of the longitudinal shank. The walls of the grooves provide surface area on the distal end of the probe in planes generally prependicular ot the axis of the probe. The additional surface area increases the tissue fragmenting surface area of the distal end of the probe without increasing the diameter of the distal end of the probe.
En général, la sonde ultrasonique utilisée dans un procédé de fragmentation amélioré, comprend une tige (11) longitudinale constituée d'une extrémité (12) proximale, d'une extrémité (13) distale et d'un corps (14). Le corps (14) rejoint l'extrémité proximale et l'extrémité distale. L'extrémité proximale de la tige longitudinale comporte un raccord (15) qui relie la tige à une source d'énergie vibrationnelle ultrasonique. L'extrémité distale de la tige longitudinale peut avoir une pointe (16) émoussée ou de forme ogivale. Le corps comporte une ou plusieurs rainures (17) proches de la pointe qui entourent le corps de la tige longitudinale. Les parois des rainures forment une surface sur l'extrémité distale de la sonde dans des plans généralement perpendiculaires à l'axe de la sonde. La surface supplémentaire augmente la surface de fragmentation des tissus de l'extrémité distale de la sonde sans augmenter son diamètre.
