The Absorbable Hemostatic Microspheres the medical use hemostatic materials applied for surgeries to stop bleeding. Due to the absorbable hemostatic microspheres' characters of absorbable, it can be absorbed by our body after it is applied on the wound area. After days of absorption, it will gradually degraded within our body, so we don't need to take a secondary operation to take the wound dressing materials out. However, there are many types of materials of absorbable hemostatic microspheres. This article will tell you the difference among these types of materials.
Gelatin
Gelatin can be applied as a material of degradable polymers and hemostatic agents in absorbable hemostatic microspheres. Gelatin in absorbable hemostatic microspheres mainly absorbs water in the blood to cause platelet concentration, reducing the liquid in the wound site while increasing the platelet's aggregation ability, and then forms a certain pressure on the surrounding blood vessels. After absorbing water and swelling, it blocks the wound to stop bleeding.
Chitosan
Chitosan is a natural polysaccharide with good biocompatibility and the ability to promote platelet adhesion. It has good hemostasis effects and is suitable for different types of wounds. What's more, chitosan has the advantages of non-toxic, non-antigenic, and has antibacterial activity. Chitosan can promotes wound healing, giving it good properties as a hemostatic material. It can agglutinate red blood cells, stimulates platelets, activates the complement system and other blood components to promote coagulation.
Collagen
Collagen is widely present in the connective tissue of animals. As a hemostatic material, it can activates coagulation factors and promotes blood coagulation. Collagen hemostat is also biocompatible and biodegradable, which helps wound healing.
Cellulose
Cellulose materials are widely made into many kinds of hemostatic products such as medical absorbable hemostatic gauze, hemostatic sealants and absorbable hemostatic microspheres. It can absorb blood, promote platelet aggregation and thrombosis. With the advantages of absorbable and degradable, it is widely used as hemostatic products. For example, Surgiclean Fibril Absorbable Hemostat, it made of cellulose, and has the characteristics of innovative fibril three-dimensional structure, rapid hemostasis, full absorption, no residue, broad-spectrum and long-lasting antibacterial. It is suitable for hemostasis in various conventional surgical operations and laparoscopic operations.
Due to the plant-based material, it has better biocompatibility and will leave no residue to our bodies.

Potato Starch
Potato starch can also be applied as the material of absorbable hemostatic microspheres. Due to its plant-based material, it has no animal origin and is of great biocompatibility to our body. For example, Surgiclean Absorbable Hemostatic Powder is made of potato starch material, and it is made by emulsification and crosslinking technology. So the raw material is free of animal origin, it is aseptic and pyrogen-free, with less side effect and with better biocompatibility.
Surgiclean Hemostatic Fiber Gauze
No matter what kind of absorbable hemostatic microsphere, when the it is sprayed on the local wound, the tiny particles in the hemostatic powder act as a molecular sieve, causing the platelets, red blood cells and fibrin formed elements in the blood to aggregate on the surface of the particles, forming a gel-like mixture to achieve the purpose of immediate hemostasis.
