The present invention relates to an automatic fat injection technology for transplantation, and more particularly, a fat injection mode to be transplanted is set and the fat is automatically adjusted and injected according to the fat injection mode set during the fat transplantation process. It relates to an automatic fat injection device for transplantation.

Fat transplantation refers to surgery in which the patient's fat is collected, the fat is purified, and then placed in the required area of the patient. There are various types of self-organizations used to fill depressions or irregularities in the subcutaneous tissue of the patient, such as dermis, muscle, fascia, fat, bone, and cartilage, but fat is the most widely used as an advantage that can be easily obtained.

The recent Micro-Fat Graft is less destroyed in the process of collecting fat, and only pure fat is added by purifying the impurities of the collected fat. Instead of putting a large amount in one area, several layers The engraftment rate is improving by putting it in.

The method of using a syringe as a tool for fat grafting is already widely known and generally used, but it is presumed that everyone injects with human force, so it is not only inconvenient to use, but also the uneven injection speed adversely affects the performance of the procedure. There were problems such as affecting.

In particular, if the transplant site is wide and the amount of fat to be transplanted is large, it is difficult to perform a uniform transplantation as a whole, and accordingly, problems such as local clustering or flowing down in an unwanted direction may occur.
