【発明の詳細な説明】 冷却可能な中ぐりブシュ 技術分野 本発明は、請求項1の前提部分に記載の中ぐりブシュに関する。 背景技術 中ぐりブシュは、骨接合において、穿孔、ねじ切りに汎用され、更に、部分的 には、骨固定ねじ、キルシュナー鋼線、シャンツ(Schanzschen)ねじ、または シュタインマンピンの取付に使用される。その理由は、多様である。開放接近法 (offenem Zugang)による骨接合の場合、中ぐりブシュは、回転器具に対する軟 部組織の巻付を阻止する。中ぐりブシュは、更に、回転器具のスリップを阻止し 、作業工程(例えば、穿孔、ねじ切り、移植具取付)においてガイドとして役立 つ。有床(プレート)骨接合術の場合、中ぐりブシュは、特にプレートの対称性 に適合された形状にもとづき、プレート孔に正しく据付られる中ぐり孔を見つけ るのに役立つ。穿刺切開による骨接合の場合、例えば、創外固定具を取り付ける 時、中ぐりブシュは、トロカールを補足した状態において、一定の穿孔路および 定着路を見つけるのに役立つ。“作業路”の決定後、中ぐりブシュの位置を変更 せずに中ぐりブシュを介して各種器具(穿孔器、ねじタップ、長さ測定器)およ び移植具(ねじ、キルシュナー鋼線、シャンツねじ、シュタインマンピン)を導 入できる。多様な骨接合術の各種の移植具および各種の手術技術に適合された中 ぐりブシュの特殊な形状によって、多種ながら何れも同一の役割を有する中ぐり ブシュが生ずる。これに関する例として、特に、有床骨接合術のための圧縮式中 ぐりブシュを提示するヨーロッパ特許公開第0460447号を挙げることがで きる。 この中ぐりブシュおよび先行技術の別の中ぐりブシュの場合、穿孔時および移 植具取付時に著しい摩擦熱が発生するという問題点がある。穿孔またはねじ切り による骨の切削加工時、機械的仕事の大半が熱に変換される。移植具の取付につ いても同断である。なぜならば、この場合、移植具と骨との間の摩擦によって熱 が発生するからである。この発生熱は、骨または軟部組織の熱的損傷を招くこと になる。 別の分野において、内部冷却式穿孔器によって上記熱発生を阻止することが試 みられている。しかしながら、骨接合の分野にもこの方策を採用できるようにす るには、器具およびボール盤の極めて煩瑣で高経費の改造が必要である。従って 、別の解決法を探さなければならなかった。 発明の開示 この場合、本発明は、その対策を講ずるものである。本発明の課題は、器具も ボール盤も改造する必要のないよう、冷媒を中ぐりブシュに直接に導入できる形 式の中ぐりブシュを創成することにある。 設定課題は、本発明によれば、請求項1の特徴を有する中ぐりブシュによって 解決される。 本発明は、各種の態様で実現できるが、冷媒は、常に、中ぐりブシュに直接に 導入される。本発明によって達成される利点は、かくして、生理的食塩水または リンゲル液からなる冷媒が、直接に作業領域に達し、かくして、直接的で効果的 な温度低下を誘起するということにもとづく。 図面の簡単な説明 本発明の実施例を図示し、以下に、詳細に説明する。 図1は、本発明に係る中ぐりブシュ縦断面図である。 図2は、図1の線II−IIに沿う横断面図である。 図3は、二重壁中ぐりブシュの縦断面図である。 図4は、図3の線IV−IVに沿う横断面図である。 発明を実施するための最良の形態 図1に示した中ぐりブシュは、本質的に、保持取手9を有する中空円筒体7か らなる。中空円筒体7は、器具または移植具を導入するための上端1と、ギザギ ザの冠状に構成され骨上に載せ得る下端2とを有する。 保持取手9は、冷媒用接続管3として構成され、この目的のため、内部に延び 、冷媒を中ぐりブシュの内部5に直接に導入できるダクト4を有する。冷媒用接 続管3は、ホースのための管継ぎ手11を有し、従って、器具、移植具および骨 を冷却する冷媒を注射器によって中ぐりブシュに導入できる。 図2に示した如く、中空円筒体7は、中ぐりブシュ内部5の冷媒の循環を容易 にするため、縦溝6を有する。しかしながら、このような縦溝6を省くこともで きる。この場合、十分量の冷媒を導入できるよう、使用器具に比して中空円筒体 7の自由空間を拡張すればよい。 図3、4に、中ぐりブシュの二重壁構造を示した。この中ぐりブシュは、図1 の実施例と同様に構成されている。しかしこの場合には、中空円筒体7内に、別 の中空円筒体8が設けてあり、かくして、双方の中空円筒体7、8の間には、保 持取手9のダクト4と連通し、冷媒用接続管3を介して冷媒の供給を受ける中空 スペース10が形成される。Detailed Description of the Invention   Coolable boring bush     Technical field   The invention relates to a boring bush according to the preamble of claim 1.     Background technology   Boring bushes are commonly used for drilling and threading in osteosynthesis, and also for partial Bone fixation screws, Kirschner steel wires, Schanzschen screws, or Used to attach Steinmann pin. There are various reasons. Open approach In the case of osteosynthesis by (offenem Zugang), the boring bush is soft against the rotating device. Prevents the wrapping of the organization. The boring bush also prevents slipping of rotating equipment. , Serves as a guide during work processes (eg drilling, threading, implant attachment) One. In the case of a bed (plate) osteosynthesis, the boring bushes have a particular symmetry of the plate. Find a boring hole that will be properly installed in the plate hole based on the shape adapted to To help you. For osteosynthesis by puncture incision, for example, attach external fixator At the same time, the boring bush, when supplemented with the trocar, has a constant drilling path and Helps find a root. After determining the "work path", change the position of the boring bush Without using the boring bush, various instruments (piercer, screw tap, length measuring instrument) and And implants (screws, Kirschner steel wires, shunts screws, Steinmann pins) You can enter. Adapted to various implants for various osteosynthesis and various surgical techniques Due to the special shape of the boring bush, various boring boring have the same role. Bush occurs. Examples of this include, among other things, the compression type for bedded osteosynthesis. Mention may be made of European Patent Publication No. 0460447 which presents a bush. Wear.   In the case of this boring bush and another boring bush of the prior art, during drilling and transfer There is a problem that significant frictional heat is generated when attaching the planting tool. Perforated or threaded Most of the mechanical work is converted into heat when cutting bones. To install the implant The same is true. Because, in this case, heat is generated by the friction between the implant and the bone. Is generated. This heat generated can cause thermal damage to bone or soft tissue. become.   In another area, it has been tried to prevent the above heat generation by internally cooled punches. It is seen. However, it will be possible to adopt this strategy in the field of osteosynthesis. To do so requires extremely complicated and costly modifications of the equipment and drilling machine. Therefore , Had to look for another solution.     Disclosure of the invention   In this case, the present invention takes measures against it. The object of the present invention is to Refrigerant can be directly introduced into the boring bush so that the drilling machine does not need to be modified. The purpose is to create a boring bush for the ceremony.   According to the invention, the setting task is by means of a boring bush having the features of claim 1. Will be resolved.   The present invention can be realized in various modes, but the refrigerant is always directly applied to the boring bush. be introduced. The advantages achieved by the present invention are thus that of saline or The refrigerant consisting of Ringer's liquid reaches the working area directly, thus direct and effective It is based on inducing a large temperature drop.     Brief description of the drawings   Exemplary embodiments of the invention are illustrated and described in detail below.   FIG. 1 is a vertical cross-sectional view of a boring bush according to the present invention.   2 is a cross-sectional view taken along the line II-II in FIG.   FIG. 3 is a vertical cross-sectional view of a double wall boring bush.   FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG.     BEST MODE FOR CARRYING OUT THE INVENTION   The boring bush shown in FIG. 1 is essentially a hollow cylinder 7 with a holding handle 9. Consists of The hollow cylinder 7 has a top end 1 for introducing an instrument or an implant and a serrated shape. A lower end 2 which is configured in the shape of a crown and can be placed on the bone.   The holding handle 9 is constructed as a connecting pipe 3 for the refrigerant and for this purpose extends inside. It has a duct 4 through which the refrigerant can be directly introduced into the inside 5 of the boring bush. Refrigerant contact The follower tube 3 has a tube fitting 11 for the hose and is therefore suitable for instruments, implants and bones. A coolant for cooling the can be introduced into the boring bush by means of a syringe.   As shown in FIG. 2, the hollow cylindrical body 7 facilitates the circulation of the refrigerant inside the boring bush 5. The vertical groove 6 is provided. However, it is possible to omit the vertical groove 6 like this. Wear. In this case, the hollow cylinder should be compared to the equipment used so that a sufficient amount of refrigerant can be introduced. The free space of 7 should be expanded.   3 and 4 show the double wall structure of the boring bush. This boring bush is shown in Fig. 1. The configuration is similar to that of the above-mentioned embodiment. However, in this case, in the hollow cylindrical body 7, another A hollow cylindrical body 8 is provided, and thus a space between the two hollow cylindrical bodies 7, 8 is retained. Hollow that communicates with the duct 4 of the handle 9 and receives the supply of the refrigerant through the refrigerant connecting pipe 3. A space 10 is formed.
