Micro Fat Harvesting Cannula: Techniques for Effective Adipose Tissue Collection

by:Dino     2024-03-26


Fat grafting has become an increasingly popular technique in plastic and reconstructive surgery, allowing for natural-looking and long-lasting results. In recent years, the emphasis has shifted towards harvesting and utilizing micro fat grafts, as they have been found to have distinct advantages over larger fat grafts. Micro fat grafts, consisting of smaller clusters of adipose tissue, offer improved survival rates and enhanced contouring capabilities. To maximize the potential of micro fat grafting, the use of specialized instruments, such as the Micro Fat Harvesting Cannula, has been developed. In this article, we will explore the techniques for effective adipose tissue collection using the Micro Fat Harvesting Cannula.

The Importance of Effective Adipose Tissue Collection

Effective adipose tissue collection is crucial to the success of fat grafting procedures. It involves the careful extraction of viable adipose cells while minimizing trauma to the surrounding tissues. The quality of adipose tissue harvested directly impacts the survival and longevity of the grafted fat cells.

The Micro Fat Harvesting Cannula: A Game-Changer

The Micro Fat Harvesting Cannula has revolutionized the field of fat grafting by providing plastic surgeons with a specialized instrument designed for harvesting micro fat grafts. This cannula features a small-diameter tube with multiple side holes, allowing for precise and controlled aspiration of adipose tissue. The use of the Micro Fat Harvesting Cannula ensures minimal damage to the harvested adipose cells and surrounding structures, leading to improved graft survival and more predictable outcomes.

Techniques for Effective Adipose Tissue Collection

* Preparation and Patient Positioning: Before starting the adipose tissue collection process, thorough patient evaluation and preparation are essential. The patient should be positioned comfortably, allowing access to the desired areas for fat harvesting. Preoperative marking is performed to identify the target sites for grafting and determine the areas of excess adipose tissue.

* Tumescent Solution Administration: The next step involves the administration of a tumescent solution, which is a combination of local anesthetic agents and vasoconstrictors. This solution is infiltrated into the target areas to facilitate fat removal while minimizing bleeding and discomfort during the procedure. The tumescent solution also helps to dislodge the fat cells, making them easier to harvest.

* Incision Placement: Once the tumescent solution has taken effect, small incisions are made in inconspicuous locations, typically less than 1 cm in length. The incisions are strategically placed to allow access to areas rich in adipose tissue while ensuring minimal visible scarring. Careful consideration of incision placement is essential to maintain aesthetic outcomes.

* Micro Fat Harvesting Cannula Technique: The Micro Fat Harvesting Cannula is then inserted through the incisions and the adipose tissue is harvested. The cannula is connected to a low-pressure suction system, allowing for the controlled aspiration of fat cells. The surgeon utilizes a back and forth motion with gentle pressure to harvest fat grafts in a careful and meticulous manner. The use of smaller side holes in the cannula prevents the aspiration of unwanted tissues, such as blood vessels and fibrous structures, while selectively targeting viable adipose cells.

* Tissue Processing and Reinjection: Once an adequate amount of adipose tissue is harvested, it is processed to separate the fat cells from blood, oil, and other unwanted substances. This can be achieved through centrifugation or filtration methods. The processed fat is then transferred into syringes for reinjection into the desired target areas. The micro fat grafts are carefully layered and meticulously placed to achieve the desired contour and volume.

Advantages of Micro Fat Harvesting Cannula Technique

The use of the Micro Fat Harvesting Cannula offers several advantages over traditional fat harvesting techniques:

* Improved Viability: The small-diameter tube and multiple side holes of the cannula allow for the gentle extraction of micro fat grafts, minimizing trauma to the adipose cells. This results in improved graft survival rates compared to larger fat grafts.

* Enhanced Contouring capabilities: Micro fat grafts can be more precisely positioned, enabling the surgeon to sculpt and shape the target areas with greater accuracy. This allows for superior contouring capabilities and natural-looking results.

* Reduced Downtime: The Micro Fat Harvesting Cannula technique is associated with minimal scarring and reduced recovery time. The small incisions required for cannula insertion heal quickly, resulting in shorter downtime for patients.


Micro fat grafting has emerged as a promising technique in plastic and reconstructive surgery, offering natural results and long-lasting outcomes. With the development of specialized instruments such as the Micro Fat Harvesting Cannula, effective adipose tissue collection has become more accessible than ever before. The use of this cannula allows for precise and controlled aspiration of micro fat grafts, leading to improved graft survival and enhanced contouring capabilities. By incorporating the techniques discussed in this article, plastic surgeons can optimize their fat grafting procedures, providing patients with satisfying and transformative results.
