Description

Fat filling injector capable of accurately controlling feeding amount

Technical Field

The utility model belongs to the technical field of fat transplantation and specifically relates to a but syringe is used to fat packing of accurate control feeding volume is related to.

Background

Fat transplantation refers to the process of sucking excessive fat from fat-rich parts, such as waist, abdomen, thigh, etc., standing or isolating to obtain large amount of granular fat, preparing fat by-products such as nanometer fat, fat glue, etc., and injecting into desired parts, such as temple depression, french-mark depression, lacrimal groove, apple muscle, etc., to achieve the purpose of improving aging face appearance and making face younger. In addition, it can also be used for treating intractable wound and scar deformity. The preparation method has more advantages, belongs to active autologous materials, has no rejection, can generate expression and motion functions, and has wide clinical application. Autologous fat filling may be performed twice or even multiple times in a large area to ensure cell viability due to different filled areas. Not all sites require secondary filling. Whether filling is needed or not is judged according to three key factors: the body has no ACME-TEA basal nutrition, the size of the filling part and the blood circulation of the filling part. For example: small local depressions, such as the lacrimal sulcus, the earlobe, small tissue fills, and it may be sufficient to fill with fat once. Although large local depressions such as forehead, apple muscle, cheek, and chin can provide good blood circulation for transplanted fat, the filling may be performed 2-3 times. Like this position of temple, because the manadesma tissue is more, do not inject the muscle surface during the injection, natural blood transports poorly, probably needs to carry out 2~3 times and fills and can reach the effect.

The prior fat filling device (fat filling injector) is a fat gun, and the main structure of the fat filling device is that the injector for injecting fat is arranged in a propelling device similar to a gun body structure, the prior fat gun (fat filling injector) only has a simple fat injection function, the problem of fat over-injection or too little injection is easy to occur in the specific using process, the postoperative recovery effect is not good easily caused by the fat over-injection, the expected aesthetic degree is influenced, the secondary compensation injection is caused by the fat too little injection, the labor and the time are wasted, and the economic cost is increased, so that the fat injector capable of accurately controlling the fat feeding amount (injection amount) is urgently needed.
