Benefits of technology

"The patent describes a surgical probe apparatus that can simultaneously treat body fat and remove the byproducts of treatment using a laser and a vacuum. The apparatus includes a hand piece with an optical system and a suction port. The therapeutic light is delivered to the area of tissue through the optical system while the suction port removes the byproducts. The apparatus can also include a sensor to monitor the tissue properties and a processor to control the delivery of therapeutic light based on the sensor signal. The technical effect of this invention is to improve the effectiveness of laser treatment by simultaneously removing the byproducts of treatment."

Problems solved by technology

For such techniques for laser skin tightening treatment, it has been difficult to control the depth and amount of energy delivered to the collagen without also damaging or killing the dermal cells.
Much of the energy of the treatment pulse is wasted due to scattering and absorption in the outer epidermal layer, and the relatively high pulse energy required to penetrate this outer layer can cause pain and epidermal damage.
The source emits a treatment output, for example an output pulse that is conveyed by the fiber to the dermis, which causes collagen shrinkage within the treatment area, thus tightening the skin.

Embodiment Construction

[0030]FIG. 1 shows an embodiment of a laser liposuction probe 100. The laser liposuction probe 100 includes a surgical hand piece 105 that supports both a surgical waveguide cannula 110 and a suction unit cannula 115. The surgical waveguide cannula 105 supports a surgical waveguide 120. The surgical waveguide 120 delivers energy through the liposuction probe 100; the suction unit cannula 115 functions to remove a byproduct through the liposuction probe 100.

[0031]In an exemplary embodiment of the laser liposuction probe 100, the surgical hand piece 105 merges the surgical waveguide 120 and a suction tube 125 into the surgical waveguide cannula 110 and the suction unit cannula 115, respectively. In some embodiments, the surgical waveguide cannula 110 may have a diameter of approximately 2-4 mm. In some embodiments, the suction unit cannula 115 may have a diameter of approximately 0.5-1.0 mm. In some embodiments, the surgical waveguide 120 may be a fiber optic waveguide.
