Description
【0001】[0001]
本考案は、歯科治療時に使用されるラチェットレンチに関する。 The present invention relates to a ratchet wrench used in dental treatment.
【0002】[0002]
円筒型の人工歯根を顎骨に設けられた孔へ挿入する場合、人工歯根に一方向の 回転運動を多分の力をかけて行なう必要がある。そこで、約1/2回転以下の回 転運動を反復させるだけで人工歯根に一方向の回転運動を行なわせしめるラチェ ットレンチ工具が使用されている。 When inserting a cylindrical artificial tooth root into the hole provided in the jawbone, it is necessary to apply a sufficient amount of force to the artificial tooth root in one direction. Therefore, a ratchet wrench tool is used that causes the artificial tooth root to rotate in one direction only by repeating a rotating motion of about 1/2 rotation or less.
【0003】[0003]
この様なレンチ工具は、人工歯根を挿入する為の工具であるだけでなく、顎骨 に挿入された人工歯根を引き抜く為に、逆方向への回転が行なえる様な構造も必 要である。 Such a wrench tool is not only a tool for inserting an artificial tooth root, but also needs a structure that can be rotated in the opposite direction in order to pull out the artificial tooth root inserted in the jawbone.
【0004】[0004]
上記に鑑み本考案は、長い柄を持ち、前記柄の一端部には、人工歯根の上部を 保持する為の保持部材の上部に設けられた円筒歯車部を挿入するための円筒歯車 用孔が形成され、前記円筒歯車用孔に一端が突出し、他端が前記柄の側面に固定 された回転用部材とした歯科治療用レンチにより、レンチを裏がえすだけで、反 対方向の回転運動が得られ、操作性の秀れたレンチ工具を実現した。 In view of the above, the present invention has a long handle, and one end of the handle has a cylindrical gear hole for inserting a cylindrical gear portion provided on an upper part of a holding member for holding an upper part of an artificial tooth root. With the dental treatment wrench that is formed and has one end protruding into the hole for the cylindrical gear and the other end fixed to the side surface of the handle, the wrench can be turned upside down to rotate in the opposite direction. The resulting wrench tool has excellent operability.

図1に於いて、(11)は円筒歯車用孔であり、人工歯根の上部を保持する為の保 持部材の上部に形成された円筒歯車部を挿入する為の部分である。(12)は柄であ り、把持部を形成している。(13)は孔部であり、円筒歯車用孔の側面に内外を貫 通する様に設けられている。(14)は回転用部材であり、一端は、孔部(13)を通し て円筒歯車用孔(11)に突出し、他端は、柄(12)の側面にロウ着等して固定されて いる。固定部を(15)に示す。回転用部材(14)に於ける円筒歯車用孔(11)に突出し た一端部には、長手方向に斜めにカット面(16)が形成されている。回転用部材(1 4)は、他端のみ固定されている為、その一端部は円筒歯車用孔に於いて、内外へ 弾力性を有する。又、孔部(13)は、回転用部材(14)の一端部の弾力性を防害しな い様な大きさを有する。図1で示した実施例全体を本体(01)とする。 次に上記で説明した実施例の動作を図2並びに図3を参照して説明する。図2 は、人工歯根(21)と保持部材(22)とが接続した状態を示したものである。保持部 材(22)は、人工歯根(21)の上部から被せ、リング状の弾性部材(25)で、人工歯根 (21)の側面を押圧し、人工歯根(21)を保持する。保持部材(22)の上部には、円筒 歯車(23)が形成されている。保持部材(22)によって、保持された人工歯根(21)は 、予じめ穿設された顎骨に、軽く、挿入される。次に本体(01)の円筒歯車用孔(1 1)を保持部材(22)の円筒歯車(23)に挿入する。回転用部材(14)の一端部(カット 面(16)付近)は、円筒歯車(23)の中腹に位置する。 次に図3で示す様に、本体(01)の柄(12)をB方向に1/2回転以下分だけ回転 させる。回転用部材(14)は、円筒歯車(23)の歯側面と接触し、歯側面を押す様に 、保持部材(23)をB方向に回転させる。 本体(01)の柄(12)をB方向に1/2回転以下分だけ回転させた後、逆方向であ るA方向に同じ分だけ回転させる。回転用部材(14)は、円筒歯車(23)の表面を滑 るため、保持部材(22)は、回転しない。この時、カット面(16)は、滑りを促進さ せる。以上の動作を繰り返すことにより、保持部材(22)並びに人工歯根(21)は、 B方向にだけ、回転する。 次に本体(01)を裏返して上述と同じ動作を行なう。この時、保持部材(22)並び に人工歯根(21)はA方向にだけ回転する。この様に本体(01)を裏返すだけで、人 工歯根(21)の回転方向を変えることができ、顎骨孔への結合、離脱が自在となる 。 In FIG. 1, (11) is a hole for a cylindrical gear, which is a portion for inserting a cylindrical gear portion formed on an upper portion of a holding member for holding an upper portion of an artificial tooth root. (12) is a handle and forms a grip. (13) is a hole, which is provided on the side surface of the cylindrical gear hole so as to penetrate the inside and outside. (14) is a rotating member, one end of which is projected into the cylindrical gear hole (11) through the hole (13), and the other end of which is fixed to the side surface of the handle (12) by brazing or the like. There is. The fixed part is shown in (15). A cut surface (16) is formed obliquely in the longitudinal direction at one end of the rotating member (14) protruding into the cylindrical gear hole (11). Since only the other end of the rotating member (14) is fixed, one end of the rotating member (14) has elasticity inward and outward in the hole for the cylindrical gear. Further, the hole portion (13) has a size that does not impair the elasticity of the one end portion of the rotating member (14). The whole of the embodiment shown in FIG. 1 is a main body (01). Next, the operation of the above-described embodiment will be described with reference to FIGS. FIG. 2 shows a state in which the artificial tooth root (21) and the holding member (22) are connected. The holding member (22) covers the artificial tooth root (21) from above, and the side surface of the artificial tooth root (21) is pressed by the ring-shaped elastic member (25) to hold the artificial tooth root (21). A cylindrical gear (23) is formed on the upper part of the holding member (22). The artificial tooth root (21) held by the holding member (22) is lightly inserted into the pre-drilled jawbone. Next, the cylindrical gear hole (11) of the main body (01) is inserted into the cylindrical gear (23) of the holding member (22). One end of the rotating member (14) (near the cut surface (16)) is located in the middle of the cylindrical gear (23). Next, as shown in FIG. 3, the handle (12) of the main body (01) is rotated in the B direction by 1/2 turn or less. The rotating member (14) contacts the tooth side surface of the cylindrical gear (23) and rotates the holding member (23) in the B direction so as to push the tooth side surface. After rotating the handle (12) of the main body (01) in the B direction by 1/2 rotation or less, rotate it in the opposite direction A by the same amount. Since the rotating member (14) slides on the surface of the cylindrical gear (23), the holding member (22) does not rotate. At this time, the cut surface (16) promotes sliding. By repeating the above operation, the holding member (22) and the artificial tooth root (21) rotate only in the B direction. Next, the main body (01) is turned over and the same operation as described above is performed. At this time, the holding member (22) and the artificial tooth root (21) rotate only in the A direction. In this way, simply rotating the body (01) inside out can change the direction of rotation of the artificial tooth root (21), and it can be freely connected to and removed from the jawbone hole.
