A Low-cost, Sterile System for Fat Collection Using a Syringe Tube as a Reservoir

Fat grafting is a widely performed procedure in the field of plastic surgery. It involves fat extraction, processing, and injection into a recipient site. It is imperative that the fat is collected and processed in a sterile system. A wide variety of equipment is required to perform the procedure (eg, a liposuction device, a vacuum pump, and syringes). Limitations often arise in the operating room, especially in low-resource areas, where task-specific equipment might be unavailable. This can present an opportunity for the surgeon to improvise and create a temporary solution. In this report, we describe our solution in dealing with the unavailability of a sterile vacuum pump canister during a large volume fat grafting procedure. We constructed a sterile reservoir using two syringes, through which negative pressure was delivered without breaking sterility. The items used were a 60-cm(3) syringe barrel, a 10-cm(3) syringe barrel, a 60-cm(3) syringe plunger seal, a tube connected to the nonsterile vacuum pump, and the liposuction cannula. This technique allowed us to extract the fat in a sterile environment under the assistance of a suction device. Our novel technique was used for harvesting fat in a sterile reservoir, while still utilizing the assisted suction from the nonsterile vacuum pump, without breaking sterility.
