Abstract

An improved liposuction handle incorporates a vacuum control for regulating the amount of suction applied during the liposuction procedure. An alternative embodiment allows for sequential performance of both the step of administering anesthetic to the surgical area and performing the liposuction procedure by the same instrument, the device additionally allowing for sterile collection of cells and tissue. Additionally, an improved liposuction method is disclosed, particularly suited for performance under local anesthesia.

Claims

1. A method for the removal of subcutaneous material, comprising:

providing a surgical vacuum device having a proximal end, a distal end and a central lumen extending therethrough, said proximal end comprising a container housing adapted to removably receive a container in communication with the central lumen;

placing a remotely located anesthetic reservoir in fluid communication with the lumen, by way of a vent extending through the wall of said device and into the lumen;

removably securing a container within the container housing;

drawing a selected amount of anesthetic from the reservoir into said container through said lumen;

expressing anesthetic from said container through said lumen and into the subcutaneous material; and

thereafter connecting a vacuum cannula in communication with the lumen and applying a vacuum to the lumen to remove subcutaneous material through the vacuum cannula.

2. The method of claim 1, wherein the container is a plunger activated syringe body.

3. The method of claim 2, wherein said step of applying a vacuum is performed by connecting a vacuum source to said syringe body.

4. The method of claim 3, wherein said step of applying a vacuum comprises connecting said vacuum source to a vacuum attachment, said attachment adapted to provide air-tight communication between said syringe body and said vacuum source.
