Definitions

  • the distal region includes a plurality of indented surfaces. Each indented surface defines opposed surface regions. A first set of the plurality of indented surfaces is aligned along a first side of the body, and a second set of the plurality of indented surfaces is aligned along a second side of the body opposite the first side. A first of the plurality of indented surfaces is circumferentially offset from a second of the plurality of indented surfaces.
  • the indented surface is defined in an outer surface of the distal region of the body.
  • the body defines an interior lumen and the indentation is in fluid communication with the lumen. Alternatively, the indentation has a closed bottom. In other embodiments, the body defines an interior bore and the indentation is located on a surface of the bore.
  • Ultrasonic vibrations applied to probe proximal end 14 produce a longitudinal standing wave in the probe causing distal end 12 to vibrate.
  • a step-down section 18 between proximal end 14 and mid region 16, and another step-down section 20 between mid region 16 and shank 13 amplify the ultrasonic vibrations delivered from proximal end 14 to distal region 12.
  • amplification can be achieved by modifying an internal wall of the probe, as described in Podany et al . , titled ULTRASONIC LIPOSUCTION PROBE, filed December 31, 1997, incorporated by reference herein.
  • Probe 10 can be made from, for example, titanium, aluminum, or stainless steel. Slots 26, 28 are typically machined into distal region 12 by, for example, milling or electro-discharge machining. Slots 26, 28 have a width, w, of about 0.06 inch, and a depth, d, of about 0.055 inch. The radius of curvature, R, of curved regions 30 is about 0.025 inch. Main portion 17 of distal region 12 and mid region 16 preferably have the same outer diameter, for example about 0.2 inch. Distal portion 15 of distal region 12 has a diameter of about 0.175 inch. Proximal end 14 and shank 13 have outer diameters of about 0.5 inch and 0.15 inch, respectively. Lumen 22 has a diameter of about 0.1 inch. The length of distal region 12 from distal opening 24 to a juncture 38 located between distal region 12 and shank 13 is in a range of about 0.25 to 0.4 inch.
  • a portion of the region near the intersection between shelf 218 and surface 220 may communicate with lumen 214.
  • a distal region 213 similar to that of distal region 212 (FIG. 3A) includes a pair of opposed openings 215, 217 near the intersection of a shelf 219 and a cone- shaped surface 221. Openings 215, 217 communicate with a lumen 223 so that treated tissue can be aspirated through openings 215, 217, as well as through a distal opening - 9 -
  • a distal region 412 of an ultrasonic probe includes a series of raised equally spaced longitudinal ridges 414. Ridges 414 extend proximally from a distal end 416 of distal region 412 to a juncture 413 located between distal region 412 and a shank 415. Adjacent ridges define a series of surface indents 418. A lumen 420 extends through distal region 412 to an opening 422 defined by distal end 416. Surface indents 418 provide increased surface area to contact and shear, by friction, adipose tissue disposed within the grooves, thereby emulsifying the tissue at an increased rate.
  • the probe can be manually rotated by the surgeon.
  • Surface indents 418 act to provide better coupling between distal region 412 and the adipose tissue as the probe is rotated about its longitudinally axis.
  • the axially oriented indents can provide cavitation surfaces by vibrating the - 10 - probe torsionally such that pressure waves are generated from axially disposed surfaces of the indents, as described in Podany, titled ULTRASONIC PROBE, filed March 2, 1998, incorporated by reference herein. Referring to FIGS. 6A and 6B, the axially disposed indents can be circumferentially offset.

Abstract

L'invention concerne une sonde destinée au traitement des tissus par ultrasons, laquelle sonde comprend un corps longitudinal servant à transmettre les vibrations ultrasonores. Ledit corps présente une partie distale comportant une surface présentant des dents définissant des zones de surface opposées. Ces zones de surface opposées s'étendent de manière sensiblement transversale ou parallèle à l'axe longitudinal du corps. La région distale définit une pluralité de surfaces transversales disposées les unes à côté des autres et placées de façon proximale par rapport à une extrémité distale du corps.
