An osteotome device is disclosed. The osteotome device according to the present invention comprises: a body which includes a handle unit gripped by a hand, an operation unit provided at the top end of the handle unit in a horizontal direction having a strike hole formed in a longitudinal direction therein and an operation hole formed with a partial section of the strike hole downwardly extended, and a trigger provided at the handle unit to be elastically supported; a replacing chuck member which includes a replacement unit provided at one side for an osteotome with a blade to be replaced, a connection member provided at the other side, and the connection member inserted from one side of the strike hole to move forward and backward in the longitudinal direction of the operation unit; a strike member which is installed inside the stroke hole to move forward and backward and strike an end of the connection member; a strike spring which is installed inside the strike hole to elastically support the strike member in the direction of the connection member; and a strike operation unit which moves the strike member backward while getting over elasticity of the strike spring by manipulation of the trigger and then moves the strike member forward with the elasticity of the strike spring so that the blade of the osteotome cuts a bone at a bone-cut position as the strike member strikes the connection member. According to the present invention, it is possible to cut a bone with an osteotome by manipulating the osteotome device operated automatically or semiautomatically with one hand. Thus, the accuracy in bone cutting can be remarkably improved and improved convenience can be offered to a doctor. |
