Definitions
- the present invention relates to a tissue sealant mixed with collagen and fibrin, and a method of manufacturing the same. More specifically, the present invention relates to platelets contained in the blood while complementing the strength and degradability, which are disadvantages of the current fibrin sealant. It is designed to induce tissue regeneration by activating it, which greatly improves the quality and reliability of the product, so that it can be planted with a good image by satisfying various needs (customers) of consumers.
- sealant is applied to a product using cyanoacrylate, polyurethane, gelatin, fibrin, and the like.
- medical sealants are used in various areas such as skin, blood vessels, digestive organs, cranial nerves, plastic surgery, orthopedic surgery.
- the properties required for these sealants should not interfere with rapid adhesion in a water environment, sterile and nontoxic, sufficient mechanical properties on the wound surface, biodegradability, hemostatic effect and bioheal.
- Polyurethane is a material having the advantage of maintaining the flexibility of the adhesive portion, it has a good reactivity with water is cured quickly and has the advantage of maintaining the elasticity of the cured material.
- aromatic diisocyanate which is a synthetic raw material, has the disadvantage of being biotoxic.
- Glue using a gelatin is a sealant derived from a living body, and there are products obtained by crosslinking gelatin and resorcinol with formalin, and products using gelatin, polyglutamic acid and carbodiimide. These products can be toxic using chemical crosslinkers of formalin and carbodiimide. In the case of products using a formalin as a crosslinking agent, it is used in some countries, but is still under license in Japan and the like and is under examination for effectiveness.
- Fibrin glue is fibrinogen, thrombin, calcium chloride, etc. as a material, it is a product applied to the product using the principle of fibrin formation. Fast adhesion, no need of heat or pressure, bio-compatible and biodegradable properties without being influenced by the environment of the adhesive site, while physical properties and relatively low biodegradation rate compared to the sealant using synthetic materials It has the disadvantage of being fast. In order to overcome this disadvantage, efforts have been made to inhibit the fibrin degrading enzyme by adding aprotinin to slow down the decomposition rate and maintain the shape of the fibrin polymer. To make up for these drawbacks, the use of collagen as an additive will greatly contribute to supplementing the fibrin glue formulation.
- Fibrin used in fibrin glue is applied and industrialized as a natural material adhesive / hemostatic agent, and is biocompatible and biodegradable. Fibrin is generally absorbed during wound healing within a few weeks and is known to be free of side effects such as inflammatory reactions, immune responses, tissue necrosis or fibrosis. Fibrin also plays an important role in wound healing in the form of a natural support for fibroblasts. Fibrin products were established in the 1970s, and the first products were commercialized in Europe in 1982 and are still in use. Recently, many studies have demonstrated fibrin as a biotissue support, and has been applied to various fields such as orthopedic, dental, and neurosurgery.
- Collagen which can be used as an additive to compensate for the shortcomings of fibrin glue, is a structural protein component. It consists of soft tissues such as dermis, tendons / ligaments, and blood vessels, and hard tissues such as bone and cartilage. In mammals, they make up about one-third of the total protein. There are more than 20 types of collagen, and collagen type I, which forms skin, tendons, tendons, and bones, accounts for about 90% of collagen.
- the structure of collagen is a protein with a molecular weight of 300,000 Daltons (about 100,000 Daltons) consisting of three strands, and Glycine, the smallest unit of amino acids (smallest molecular weight), is repeatedly (-GXY-; Glycine). Are repeated repeatedly, where X and Y are different configurations.
- glycine accounts for 1/3 of the amino acids constituting collagen.
- collagen is used for medical purposes such as hemostatic agents, wound dressings, artificial blood vessels, and wrinkle improvement.
- hemostatic agents a product called Aviten, a collagen powder extracted from calf skin in 1974, was developed for the first time. have.
- collagen is used in medical regenerative field because it is biocompatible with human tissue and shows cell affinity, which is important for maintaining cell adhesion, growth and viability. In addition, it stimulates platelets contained in the blood to induce growth factors contained in the platelets plays a role in regenerating the missing tissue.
- the structure of the collagen triple helix structure is relatively degradable than the protein of a single structure can maintain a scaffold role in the human body.
- tissue sealant not only retains the biodegradable properties that the tissue sealant must have and does not interfere with regeneration, but also complements the physical properties of fibrin glue's lack of physical properties and slows down the degradation to provide a degradable regenerative skeleton. will be.
- fibrin glue in addition to its role as a simple sealant, it will promote tissue regeneration and accelerate the regeneration process to shorten the course of treatment.
- freeze-type the formulation in addition to freeze-type the formulation to be mounted in a pre-field type for rapid use.
- Tissue sealant is a product that is less painful than the conventional method when sutured and applied to the wound surgery area, reduces the risk of infection and shortens the operation time.
- the market size is also gradually expanding.
- development of these products will not only help tissue regeneration, but will also contribute greatly to regenerative medicine in the future as drug delivery systems and regenerative scaffolds.
