Syringe using in fat transplantation

Abstract

Provided is a syringe used in fat transplantation comprising: a cylinder having a coupling part formed at one side thereof such that a cannula, a needle or a cap is detachably coupled, an open part formed at the other end, and a flange formed at an outer periphery of the open part; a piston head installed in the cylinder; and a plunger for reciprocating the piston head, characterized in that the flange is formed separately from the cylinder, and a flange attachment structure is formed between the flange and the cylinder to detach the flange from the cylinder, wherein the flange attachment structure is comprised of a hooking projection projecting from an outer periphery of the cylinder, an insertion groove formed in an inner periphery of the flange such that the hooking projection is inserted, and a hooking groove integrally formed with the insertion groove such that the hooking projection is hooked.

Description

Technical field [0001] The present invention relates to a syringe for fat transplantation, and in particular, to a syringe used during fat transplantation. The syringe can be used as a storage container for fat tissue and can minimize the space occupied by the storage chamber, thereby increasing storage efficiency and convenience Fat transplantation. Background technique [0002] Recently, the use of fat transplantation has suddenly increased, and the scope of use has been expanding. Fat transplantation is a type of surgery that uses fat suction to transplant fat accumulated in one part of the body to another part of the body that needs fat. After fat transplantation, the remaining fat is frozen and stored in a syringe instead of a separate storage container, and then the fat is thawed for reinjection into the body. With the increase in the number of fat transplant operations, the demand for freezing devices for storing fat has also surged. In addition, since it is possible to st...

AI Technical Summary

Problems solved by technology

However, since the flanges protrude outward from the barrel, it is difficult to store the barrels next to each other, which can take up a lot of space and reduce storage efficiency

In particular, due to the advantages of low-temperature storage such as liquid nitrogen, its use range is expanding day by day, the consumption of liquid nitrogen tanks is increasing, and the large volume of liquid nitrogen tanks increases the manufacturing cost, and its storage and maintenance costs are also several times higher than those of traditional freezer

[0005] In addition, since the syringes are stored in liquid nitrogen, the barrel, plunger, and cap of the syringe may shrink suddenly, which reduces the tightness and increases the possibility of cross-contamination due to liquid nitrogen intrusion
