Definitions

  • This invention relates to a liposuction apparatus and method. More particularly, this invention relates to a liposuction apparatus optionally having a sonic or ultrasonic source with an axial lumen passage in which the shaft can be made to reciprocate in a npn-rectilinear fashion.
  • the apparatus and method may also contain the concomitant use of rectilinear reciprocation motion in addition to ultrasonic motion or energy along the shaft of said device.
  • Liposuction which literally means “fat suction” is a 10 technique to remove intact fat cells, fat globules, fat y fluids or fatty debris from the body by means of teasing, pulling, scraping, sonication, suction and/ or pressing out the debris.
  • Liposuction can be used to reduce the volume of f t in many regions of the body, but liposuction is particularly effective in such areas as the thighs and the abdomen where fat is less responsive to diet and exercise.
  • Liposuction, performed as an elective operation is one of the most common surgeries performed in the world.
  • a single lumen cannula shaft is pushed by a surgeon through skin entrance sites into the target fat in a spoke-wheel or radial fashion.
  • chronic and acute stress on the surgeon's elbow and shoulder can fatigue the surgeon, thus reducing the reproducibility of the result between the patient's right and left sides, and sometimes making for a less than optimal result.
  • a liposuction cannula passes through the target tissue, it tends to suck out or traumatize a diameter of fat that is related to the diameter of the shaft of the cannula, Ideally, one would use the smallest diameter shaft possible to reduce penetration injuries.
  • Ultrasonic liposuction cannulas were developed by Parisi et al in the late 1980' s and patented under the patents "Liposuction procedure With Ultrasonic Probe", U.S. Patent No. 4,886,791 and “Ultrasonic probe", U.S. patent No. 4,861,332 (1988). Parisi claims that the ultrasonic process "melts" fat. Only if the word “melt” is used extremely loosely and re-defined is this true. Fat stored in the body may be encapsulated in cells and is not truly solid to any degree.
  • the ultrasonic cannula uses water as a coupling medium in order to break apart fat cells and fat globules, thus releasing fat from the aforementioned cells and fibrous tissues which provide support and structure to the human fat.
  • the newest (third generation) ultrasonic liposuction cannula is basically cooled along the length of the cannula shaft by an outer metal sleeve that almo ⁇ t covers the vibrating tip.
  • Sterile cooling water passes between the hot inner vibrating shaft and the outer metal sleeve.
  • the cooling water exits at the tip of the cannula as a "bubble" of water.
  • the metal cooling sleeve leaves only a fraction of an inch of vibrating shaft (tip) exposed to the patient's tissue. This design change is alleged to reduce the tendency for thermal burns.
  • a major drawback for the third generation of ultrasonic cannulas is that there is incomplete suction of the sonicated (broken and foamy) fat Out of the patienf 8 tissues.
  • the broken down fat remaining in the patient must be crudely pressed out with rollers, suctioned out with old-fashioned cannulas or left to be "absorbed" inside the patienfs body.
  • the long term effects of leaving foamy fat and broken down fat cells behind in the body have not been determined. For example, degraded fat may cause more fibrosis of the treated areas, or the Hver or vessels may be damaged by fatty infiltration due to overload.
  • the third generation still suffers the possibility of causing thermal burns wherein a hot cannula tip strikes or harms the skin.
  • Fatty acids are a known source of inflammation in the human body and may cause the body to lay down scar tissue and other unwanted reactions. Additionally, the tunnels and unsonicated liquefied oils and their by-products likely contribute to the formation of seromas (fluid ball collections) only seen with ultrasonic liposuction procedures. Using rollers is not an optimal way to remove fat and is only partially successful. Current ultrasonic liposuction cannulas cannot bend sufficiently and still vibrate (sonicate) the desired target structures. Early generations of ultrasonic liposuction cannulas, which are still currently in use in many offices throughout the United States, incorporate large "protectors" that are screwed into the patient's skin to protect the entrance sites from burns.
  • the reciprocating devices which have been previously patented and/ or are in clinical use do cause rubbing, abrasion, shearing or tearing of the fat globules as they fall into the reciprocating cannula tip, it is possible that the true principal dynamic involved in the use of a reciprocating device is to expose a greater amount of cannula tip port to the external fat to be suctioned. For example, if a 2 mm wide by 10 mm long cannula fat entrance port were to oscillate on an arc 2 mm to the right and 2 mm to the left, the effective surface area (Size) of the port would be tripled.
  • Further embodiments of the prior art include motors for the reciprocation which are powered by electricity and/ or gas. Qose inspection of the prior art reveals that none of the gas-powered instruments utilize the available excess vacuum power that is present currently in all offices that are performing liposuction. Since the late t580's the vacuum-powered suction machines have become exceedingly strong, capable of delivering vacuums of -40 torr.
  • the non-electrical prior art basically relies upon gas-powered mechanisms that provide a positive pressure in order to generate the energy by which a reciprocating mechanism can be driven. Motors or pressurized gas cannisters cost money in that the positive pressure fluid source must be used to generate the power. Additionally, mechanization must be present within the liposuction cannula to utilize the positive pressure power.
  • the liposuction device and method of the present invention is dissimilar to the prior art apparatus in that in this invention the cannula shaft does not require two separately moving shafts in order to catch fat between two aligned "windows" or to cut and remove fat. Also, the present invention differs from the prior art in that only a single shaft is necessary to effect the removal of the target fat.
  • a second shaft or additional lumen is also in the present invention but its design, function and purpose is for the novel combination of cooling the tip of the hot vibration ultrasonic device, and optionally to equilibrate the pressure or provide additional pressure in order to allow fat to move back up the cannula shaft with greater ease as opposed to traditional and previous ultrasonic liposuction cannula shafts.
  • the liposuction device of this invention involves a novel combination of the uses of reciprocating energy (e.g. at 100 Hz) plus ultrasonic energy (e.g. at 25 KHz) in which the dual use of both energies would reduce the total energy of each specific type, i.e., reduced ultrasonic energy and reduced reciprocating energy to be used,
  • the device of this invention may uniquely use suction (vacuum/negative pressure) to cause a desired and controllable reciprocating motion of the liposuction shaft.
  • suction vacuum/negative pressure
  • vacuum pump capabihty approaches -40 torr, but optimally only mild negative pressure in the range of -10 to -15 torr is used for suctioning in order to reduce trauma to the fatty tissues.
