PURPOSE: A bone pulverizer for medical equipped with a cutting edge flux prevention function is provided to efficiently collect pulverized bone powder and prevent mix up with foreign substances. CONSTITUTION: A bone pulverizer for medical equipped with a cutting edge flux prevention function comprises an instrument body(20) which has a cylindrical shape, a flute shaped mechanical hole(24) placed one side of central inlet of the instrument body and infiltrated horizontally, an inserted supporting groove located in other side of the instrument body which is connected to the mechanical hole and has a bigger diameter than the mechanical hole(28), and a cylindrical shaped insertion hole located in upper center of the instrument body which is perpendicularly connected to the mechanical hole and shatter an inserted bone. A cutting supporting member(30) which unites with outer circumference of the instrument body is inserted to the inserted supporting groove of the instrument body. The grinding material(50) for shattering the inserted bone which is inserted through the insertion hole is coupled detachably with an operational axis(40). The operational axis inserts into center of the instrument body and rotates in order to shatter the bone.본 발명은 환자의 치료 목적을 위해 자가뼈 이식이 필요한 정형외과나 치과 임플란트의 시술시 부족한 뼈를 이식하기 위해 사용되는 뼈 분쇄기의 절삭날을 회전시켜서 삽입된 뼈를 분쇄할 때 기기의 내부에 삽입된 절삭날을 상하 방향으로 유동됨이 없이 견고한 상태로 지지할 수 있음으로써 기기와의 간섭이 발생됨이 없이 뼈를 분쇄시킬 수 있어서 분쇄된 뼛가루 속에 쇳가루와 같은 이물질이 혼합되는 현상을 방지할 수 있음과 아울러, 분쇄된 뼛가루를 효율적으로 수거할 수 있는 유동 방지기능이 구비된 의료용 뼈 분쇄기를 제공한다.
