Description

本発明は、ダウエルピン植立用の歯科用穿孔機のように、切削用ドリルの固定用チャックが可変式でない穿孔機に、違径の切削用ドリルを使用することのできるドリルアダプターに関するものである。 The present invention relates to a drill adapter that can use a cutting drill having a different diameter in a drilling machine in which a chuck for fixing a cutting drill is not variable, such as a dental drilling machine for planting dowel pins.

従来より、歯科用穿孔機の切削用ドリルは、市販ドリルを使用することができず、専用ドリルを使用していた。 Conventionally, a commercially available drill cannot be used as a cutting drill for a dental drilling machine, and a dedicated drill has been used.

従来の専用ドリルには、高価なうえに種類が少なく、素材や形状を選択することができないという欠点があり、本発明は以上の欠点を解決し、歯科用穿孔機において市販のドリルを使用できることを目的とするものである。 Conventional dedicated drills have the disadvantage that they are expensive and have few types, and materials and shapes cannot be selected. The present invention solves the above disadvantages, and a commercially available drill can be used in a dental drilling machine. It is intended.

中空の円筒管の一方の開口側にドリル状の刃を、その先端の外周の面に、単数もしくは複数設ける。そして、前記中空の円筒管の側面に、円筒管の両開口端に達する切れ込みを設ける。さらに、その切れ込みの中央に、窓状の開口部を設ける。 One or a plurality of drill-shaped blades are provided on one opening side of the hollow cylindrical tube on the outer peripheral surface of the tip. And the notch which reaches the both opening ends of a cylindrical pipe is provided in the side of the hollow cylindrical pipe. Further, a window-like opening is provided in the center of the cut.

本発明を使用することにより、歯科用穿孔機に使用する切削用ドリルを、市販ドリルの中から自由に選択することができるうえに経済的である。 By using this invention, the cutting drill used for a dental drilling machine can be freely selected from commercially available drills and is economical.

本発明の構造は、図１で示すように、中空の円筒管（１）の一方の開口側に、切り込むようにドリル状の刃（２）を、その先端の外周の面に単数もしくは複数設ける。
そして、前記中空の円筒管（１）の側面に、円筒管（１）の両開口端に達する切れ込み（３）をスリット状（溝状）に設ける。その切れ込み（３）の中央に、歯科用穿孔機の切削用ドリルを固定するネジ（４）（図２参照）が、ドリルアダプター（５）本体に干渉することもなく通すことができるように、窓状の開口部（６）を設ける。In the structure of the present invention, as shown in FIG. 1, one or a plurality of drill-shaped blades (2) are provided on the outer peripheral surface at the tip of one end of a hollow cylindrical tube (1) so as to cut. .
And the notch (3) which reaches the both opening ends of the cylindrical tube (1) is provided in the slit shape (groove shape) on the side surface of the hollow cylindrical tube (1). In the center of the notch (3), the screw (4) (see FIG. 2) for fixing the cutting drill of the dental drilling machine can be passed without interfering with the drill adapter (5) body. A window-like opening (6) is provided.

本発明の使用方法は、図２で示すように、市販ドリル（７）をドリルアダプター（５）に同心軸となるように挿入する。次に、市販ドリル（７）の挿入されたドリルアダプター（５）を、歯科用穿孔機のドリル固定台（８）に同心軸となるように挿入する。この時、歯科用穿孔機のドリル固定台（８）のネジ（４）が、ドリルアダプター（５）本体に干渉することなく、窓状の開口部（６）を通して市販ドリル（７）に直接達するようにしてネジ（４）を締める方法と、歯科用穿孔機のドリル固定台（８）のネジ（４）を、ドリルアダプター（５）の窓状の開口部（６）以外の円筒側面に当接せしめた状態を保持しつつネジ（４）で、ドリルアダプター（５）本体を締め付けることで、円筒管（１）の切れ込み（３）が締まり、間接的に市販ドリル（７）が固定される方法の２種類から選択することができるものである。
また、市販ドリル（７）の固定する方法を２種類からの選択とせず、直接的固定を目的とする窓状開口部（６）もしくは、間接的固定を目的とする切れ込み（３）のどちらか一方のみを選択した形状のドリルアダプターも含むものとする。In the method of use of the present invention, as shown in FIG. 2, a commercially available drill (7) is inserted into the drill adapter (5) so as to be concentric. Next, the drill adapter (5) into which the commercially available drill (7) is inserted is inserted into the drill fixing base (8) of the dental drilling machine so as to be concentric. At this time, the screw (4) of the drill fixing base (8) of the dental drilling machine reaches the commercial drill (7) directly through the window-shaped opening (6) without interfering with the drill adapter (5) body. In this manner, the screw (4) and the screw (4) of the drill fixing base (8) of the dental drilling machine are applied to the cylindrical side surface other than the window-shaped opening (6) of the drill adapter (5). By tightening the drill adapter (5) body with the screw (4) while keeping the contacted state, the cut (3) of the cylindrical tube (1) is tightened, and the commercially available drill (7) is indirectly fixed. You can choose from two types of methods.
Moreover, the method of fixing a commercially available drill (7) is not selected from two types, either a window-shaped opening (6) for direct fixing or a notch (3) for indirect fixing. It shall also include drill adapters with a shape that selects only one.

本発明のドリルアダプター（５）の側面の切れ込み（３）の実施例を箇条書きにする。
（イ）ドリルアダプター（５）の側面の切れ込み（３）の形状が、ドリルアダプター（５）のドリル状の刃（２）の端まで達せず、その途中でＴ字状に形成された形状。（図３参照）

（ホ）市販ドリル（７）とドリルアダプター（５）を、摩擦の力を利用して固定する方法として、ドリルアダプター（５）の側面の切れ込み（３）や窓状の開口部（６）を使用せず、市販ドリル（７）の外径とドリルアダプター（５）の内径の差を、遊びのない大きさにドリルアダプター（５）の内径を形成する。（図示せず）The following (d) and (e) are variations of the present invention that do not use the method of fixing with the screw (4).
(D) As a method of fixing the commercially available drill (7) and the drill adapter (5) using the force of the spring (9), a plurality of linear shapes are provided on the side surface of the drill adapter (5) in the same manner as (c) above. A plurality of notches (3) are formed so as not to reach both open ends, and an intermediate portion between the notches (3) and the notches (3) is formed in the axial direction of the drill (to form a recess) A spring-like elasticity is generated by applying pressure from both opening end sides), and a spring (9) shape is formed. (See Figure 6)
(E) As a method of fixing the commercially available drill (7) and the drill adapter (5) using the force of friction, the side notch (3) and the window-shaped opening (6) of the drill adapter (5) are used. Without using it, the inner diameter of the drill adapter (5) is formed so that the difference between the outer diameter of the commercially available drill (7) and the inner diameter of the drill adapter (5) is free from play.
