The present invention discloses a knife head of an ultrasonic bone knife, a cutting part (1) located at the tip of the knife head of the ultrasonic bone knife, a knife body (3) connected to a transducer, and a cutting part (1 ) And the knife rod (2) connecting the knife body (3), the cutting part (1) has a long cylindrical shape, the end converges, and a plurality of pieces are formed on the side surface of the cylindrical body. A spiral knife blade (4) is provided. When performing an operation using the knife head of the ultrasonic bone scalpel of the present invention, the knife head does not rotate, so that it does not cause damage such as curling and pulling on the living tissue. The knife head of the ultrasonic bone scalpel of the present invention is accurate in positioning, has no phenomenon of slipping or shifting on the skeleton surface, has a stable cutting process, and has high maneuverability. The knife head of the ultrasonic bone knife of the present invention can perform operations such as grinding, drilling, scraping and cutting. The knife head of the ultrasonic bone scalpel of the present invention consolidates the drilling function and the grinding function, realizes versatility with one knife, saves the operation time, and reduces the operator's fatigue.本発明は、超音波骨メスのナイフヘッドを開示し、超音波骨メスのナイフヘッドの先端に位置する切断部（1）と、トランスデューサに接続されるナイフボディ（3）と、切断部（1）とナイフボディ（3）とを接続するナイフロッド（2）とを備え、切断部（1）は、外形が長円筒体状を呈し、端部が収束し、円筒体の側面に複数本の螺旋形のナイフ刃（4）が設けられている。本発明の超音波骨メスのナイフヘッドを用いて手術を行う際、ナイフヘッドに回転を生じないため、生体組織に対して巻き反り、引っ張りなどの損害を引き起こすことはない。本発明の超音波骨メスのナイフヘッドは、位置決めが正確であり、骨格表面に滑りやずれの現象がなく、切削過程が安定であり、操縦性が高い。本発明の超音波骨メスのナイフヘッドは、研削、穴あけ、スクレーピング、断裁等の操作を実施可能である。本発明の超音波骨メスのナイフヘッドは、穴あけ機能、研削機能を集約し、１つのナイフによる多用途を実現し、手術時間を節約し、手術の術者の疲労感を軽減する。
