New Description: 【New Technical Fields】 This is a kind of adjustable micro-injection device that can be used for transplantation of liquid or semi-liquid soft tissue fillers or injection of drugs and substances, especially for soft tissue transplantation, reconstruction and surgery. Or cosmetic surgery, the filler or drug can be placed in the correct position of the human body properly, evenly and precisely, with high precision, easy operation and low cost. [Prior Art] Fat Transplantation/Fat Grafting has been in existence for more than one hundred years since the German Netiber was officially presented in the literature in 1893 (1). Fat grafting has long been regarded as a good surgical procedure for soft tissue transplantation or filling, and is therefore often used in Reconstmctive surgery or Cosmetic surgery [2], [3] 〇 in general' Possible sequelae of fat transplantation such as: absorption, infection, embolism, cyst formation, calcification, ossification, pseudotumor formation, necrosis (necrosis), asymmetry, skin necrosis/fistula formation, iatrogenic nerve/vascular injuries, and carvenous sinus thrombosis [ 4], the reason for this, most of the fat transplantation, fat inappropriate, uneven (even), or excess placement. Therefore, how to properly and evenly place fat in the correct position in clinical practice has become the most important topic in fat transplantation surgery Ίνί3·26838. According to the famous plastic surgeon C〇leman SR, “Structural Fat Grafting” proposed by the world-renowned reconstruction magazine PRS in 2-6 years: More Than a, Permanent Filler – mentions the placement of fat. Aspects - There are several arguments worthy of attention [5]: Accuracy of placement volume is extremely important when transplanting into the body, because once injected into the body, it is difficult to knead the fat tissue. • Second, in the fat transplantation surgery of the face, each time the infusion cannula is injected and the fat is pushed into the body, the volume of fat pushed must be finely controlled to only & milliliters each time. Cc). 2. In certain specific areas, such as the eyelids, the maximum amount of fat injected should be close to 丄 or even $ml. φ However, in the clinical application of the one-ml syringe recommended by Coleman SR, it is extremely difficult to accurately push the milliliter of fat in each injection, and the amount of push should be fine to έ or έ ml. It is beyond human control. In order to achieve better surgical results, Byron Medical has introduced disp0s_a_jeCtTM SYS 丽, as shown in the figure - figure, this set of traces only a 1 can reach the minimum input volume of ML, obviously not enough to achieve a smaller 丄 or M326838 and the requirements of the house. In addition, one of the DISPOS-A-JECTTM SYSTEM is connected. The milliliter syringe is a special and expensive UlerLock type one-injection syringe (1ccBd).

Luer Lock Syringe), not a general-purpose _ml injection in hospitals or clinics. The syringes are slightly less convenient and universal. When using Yan Qing (10)-Qian 01TM SYSTEM for fat transplantation operation, please refer to the figure--, you must first remove the plunger (Plunger) (81) of the syringe (8) and then the SYSTEM itself. The pusher (82) is inserted into the syringe (8) to push the secret, and the fat in the operation process must be exposed to the air, causing the fat cells to have infection and the survival rate is lowered. Moreover, since the angle of the SYSTEM and the needle (83) and the opening (84) of the needle are fixed, in the clinical application of the fat injection, the operator is unable to flexibly adjust the injection angle, and is likely to be difficult to operate. Injectable surface deviation or difficult to inject. _ The above description, based on the precision of surgery, air tightness of equipment, ease of operation and cost, it is indeed necessary to develop a new type of fat grafting device to solve many shortcomings derived from conventional technology. β Notes: [1] Neuber.
