[0002] Medical absorbable powder is widely used in clinical practice for local hemostasis, adhesion prevention, tissue fluid leakage prevention, lung air leakage sealing, and cerebrospinal fluid leakage prevention. According to the raw materials, medical absorbable powder can be generally divided into synthetic medical powder and bio-derived medical powder. The raw materials of synthetic medical powder mainly include polylactic acid, polylactide-co-glycolide, cyanoacrylates, polyethylene glycols, etc. The main sources of raw materials of bio-derived medical powder include collagen, fibrinogen, cellulose, starch, alginate, chitosan, etc.

[0003] Based on clinical needs and material properties, medical absorbable powders generally have the advantages of rapid hemostasis, ease of use, and applicability to various wounds. However, this also makes it easy for them to come into contact with other tissues, body fluids, and blood in the body when used on internal tissues during clinical use, causing them to stick together or become sticky, making it difficult for operators to accurately deliver and place them in the target area and achieve their intended effect.
