METHOD OF COMBINED LIPOSUCTION Russian patent published in 2018 - IPC A61F2/02 A61N5/67 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to plastic surgery. Performing the preoperative examination of the patient and application of the operating field contour boundaries in patient standing position with the determination of the thickness of the subcutaneous fat to be removed. Performing the required amount of anesthesia depending on the number of operated areas, their location and the volume of subcutaneous fat removed. Performing the transcutaneous puncture of the skin along the contour boundaries of the operating field, performing the uniform infiltration of subcutaneous fat by injecting into it under pressure through preliminary punctures along the contour boundaries of the operating field of the tumescence solution to create local intracellular hyperhydration of the lipocytes. After 10–15 minutes after the onset of infiltration of subcutaneous fat with tumescence solution, performing the expansion of the puncture with a blunt dilator and introduction of an infiltration cannula into the enlarged puncture. Infiltration cannula is formed by the reciprocating motion of the infiltration cannula in the entire volume of the subcutaneous fat to be removed, located close to each other in the form of a fan-like network. Introducing into the infiltrated subcutaneous fat source of destructive effects on fat cells through the expanded puncture of the hollow probe. Performing a destructive effect on fat cells with continuous linear advancement of the hollow probe in the layer of fatty tissue with simultaneous translational movement in each separately formed infiltration tunnel. At that, the effect on subcutaneous fat begins in each formed infiltration tunnel, first from the lower layers of the subcutaneous fat, followed by a transition to the overlying layers of subcutaneous fat. Performing the hollow probe extraction from the puncture and suction f the formed fatty detritus of the emulsified adipocytes from the liposuction zone using a negative pressure of 0.2–0.3 bar. At the end of the surgery applying aseptic and compression dressings. Bandaging the wound in the postoperative period using the antiseptic solutions and water-soluble ointments with simultaneous reception of medicinal preparations and carrying out of an antibacterial therapy with broad-spectrum antibiotics for 5–7 days after the operation. At that, the contour boundaries of the operating field are determined in the lower third of the face and in the neck region, the puncture site, widened by the blunt dilator, is selected in the region of the chin fold. Subcutaneous fat infiltration is performed by standard syringes. Performing the infiltration tunnels formation with approach on the face lower jaw front surface of the. At that, as a source of destructive action on fat cells a laser device is used, as an hollow probe of the destructive effect source on fat cells, an optical cannula with a fiber-optic lightguide placed into it is used. As a destructive effect on fat cells Nd:YAG laser radiation with a wavelength of 1064 nm is used. Suction of formed emulsified adipocytes fat detritus from the liposuction zone is performed by means of an aspiration cannula, wherein after the emulsified adipocytes fat detritus removal from the liposuction zone, the dermis is heated in the liposuction zone to 39–40 °C by means of an optical cannula with a placed into it fiber-optic lightguide.

EFFECT: method allows to reduce the tissue structures traumatization and postoperative complications probability and extent, reduce or eliminate facial "flews", thereby simultaneously providing modeling of the face contours, which generally leads to a pronounced tightening effect in the operated area.
