【0001】 [0001]

【発明が属する技術分野】本発明は、長菅骨骨折手術において骨折部を髄内釘でとめる際の横止めをおこなう手段に関するものであり、例えば整形外科分野における大腿骨、脛骨骨折の髄内釘横止め固定を行うためのガイドとして用いる。 The present invention relates] is related to means for performing a lateral stop when stopping in intramedullary nail to fracture in NagaKan bone fracture, for example, a femur in orthopedics, intramedullary tibial fracture used as a guide for performing nail lateral stop fixed.

【0002】 [0002]

【従来の技術】この種の整形外科手術では、髄内釘及び横止め固定を行うための髄外ガイドとして例えば図1で示すような形状のものが用いられている。 BACKGROUND OF THE INVENTION This type of orthopedic surgery, a shape shown as extramedullary guide for performing an intramedullary nail and a lateral stop fixed in FIG. 1, for example is used.

【0003】図2に示すように長菅骨骨折の髄内釘及び横止め固定は、長菅骨2に髄内釘3を骨折部4を架橋する様に挿入し、この後長菅骨2が骨折部4で回旋したり、骨折部4が開いたりしないことを目的として、スクリュー5を通常中空である髄内釘3にあいた穴6を通した後反対側の穴7を通し骨に固定する手術を行う。 [0003] intramedullary nail and horizontal NagaKan fracture as shown in FIG. 2 fastened inserts so as to cross the fracture 4 intramedullary nail 3 to NagaKan bone 2, after this length Kanhone 2 fixed but or swirling at the fracture 4, for the purpose of not or fracture 4 opens, the bone through a hole 7 on the opposite side after passing through a hole 6 which meet the screw 5 into the intramedullary nail 3 is usually hollow surgery to perform.

【0004】この時に、スクリュー5が挿入しやすいように図3に示す如く髄外ガイド1が用いられる。 [0004] At this time, extramedullary guide 1 as shown in FIG. 3 as the screw 5 is easily inserted, it is used. この髄外ガイド1は髄内釘3に取りつけられるが、一端にスクリュー5を、穴6、7に通しやすくするための横止めガイド部8がついている。 This extramedullary guide 1 is attached to Zuinaikugi 3, the screw 5 at one end and with a lateral stop guide portion 8 for facilitating through the hole 6,7. この横止めガイド部8は中空部9がある。 This lateral stop guide portion 8 has a hollow portion 9. この中空部9にドリルやガイドワイヤを通したのちスクリュー5を挿入するという手順を踏むことでスクリュー5の挿入を容易にしている。 To facilitate insertion of the screw 5 by stepping on the steps of inserting the screw 5 then through the drill and guide wire to the hollow portion 9.

【0005】 [0005]

【発明が解決しようとする課題】上記髄外ガイド1には次に述べるような解決を必要とする課題が残されていた。 Problem that requires described below as a solution in the extramedullary guide 1 THE INVENTION An object you try solving] had been left.

【0006】上記のごとく髄外ガイド1は一見スクリュー5の挿入を容易に行えるように見えるが、実際は、骨の形状に個人差があるため髄内釘3が変形したり、髄外ガイド1と髄内釘3の連結部10に遊びがあったり、ドリルやガイドワイヤを挿入する時にそれ自身が変形したり骨ですべったり筋肉でゆがんだりすることで、誤差が生じ、容易にドリルやガイドワイヤを挿入することができない場合があった。 [0006] extramedullary guide 1 as described above may seem to allow easily look insertion of the screw 5, in fact, or deformed intramedullary nail 3 because of individual differences in the shape of a bone, and extramedullary guide 1 or have play in the coupling portion 10 of the intramedullary nail 3, by itself be distorted by Bettari muscle is bone or deformed when inserting the drill and guide wire, an error occurs, the easily drill and guide wire there is a case that can not be inserted. この過程はレントゲン線透視下で行うため患者及び医療関係者がレントゲン線を被爆する量を増加させてしまっていた。 This process had gotten increasing amounts of patient and medical personnel to exposure to X-ray lines for performing under Roentgen ray fluoroscopy.

【0007】レントゲン線被爆量が多いことは生体毒性の点から問題があった。 [0007] It is often X-ray-ray exposure amount has been a problem from the point of biological toxicity.

【0008】そこで本発明は、上記した従来技術の課題を解決して横止め用スクリューが挿入しやすい髄内釘の髄外ガイドを提供する。 [0008] The present invention, lateral stop screw to provide extramedullary guide inserted easily intramedullary nail to solve the problems of the prior art described above.

【0009】 [0009]

【課題を解決するための手段】本発明による髄外ガイドの基本的構造は、従来と同様に髄内釘に連結する連結部11及び皮膚の外を髄内釘軸とほぼ平行に走る平行部1 The basic structure of extramedullary guide according to the invention According to an aspect of the parallel portion running outside the coupling part 11 and skin connected to conventional as well as intramedullary nail in substantially parallel to the intramedullary nail shaft 1
2、スクリュー等による横止め部を挿入するための穴を骨にあけるためにドリルやガイドワイヤを通すための横止めガイド部13から構成されたものであるが、横止めガイド部13のドリルやガイドワイヤを通すためのガイドホール14が複数ありドリルやガイドワイヤを同時に複数挿入できる構造になっている。 2, a hole for inserting the transverse stop portion by screws or the like are those which are composed of lateral stop guide portion 13 for passing the drill and guide wire to open the bone, drill lateral stop guide portion 13 Ya guide holes 14 for passing the guide wire has a structure in which a plurality There drill and guide wire to be more simultaneously inserted. 同時に複数挿入できる分だけ横止め用のドリルやガイドワイヤひいてはスクリューの挿入確率を向上させるものである。 It is intended to improve the drill and guide wire thus screw insertion probabilities for horizontal locking by the amount that can be multiple simultaneously inserted.

【0010】これにより髄内釘にもちいる横止め用スクリューの挿入がより容易となりひいては、レントゲン被爆量の減少が可能となる。 [0010] This allows the insertion of the lateral stop for the screw to be used for intramedullary nail is made more easily and thus, it is possible to decrease the X-ray exposure amount.

【0011】 [0011]

【発明の実施の形態】以下に、本発明による髄内釘及び横止め用スクリューについて、望ましい発明の実施の形態に基づいて詳細に説明する。 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS, the intramedullary nail and lateral locking screw according to the present invention will be described in detail based on the embodiments of the preferred invention.

【0012】第1実施例の髄外ガイドは、図4で示すように、髄内釘に連結する連結部11及び皮膚の外を髄内釘軸とほぼ平行に走る平行部12、スクリュー等による横止め部を挿入するための穴を骨にあけるためにドリルやガイドワイヤを通すための横止めガイド部13から構成されたものであるが、横止めガイド部13のドリルやガイドワイヤを通すためのガイドホール14が複数ある。 [0012] extramedullary guide in the first embodiment, as shown in Figure 4, the connecting portion 11 and the parallel portion 12 that runs outside of the skin substantially parallel to the intramedullary nail shaft coupled to the intramedullary nail, by a screw or the like Although a hole for inserting the transverse stop section is obtained composed of the lateral stop guide portion 13 for passing the drill and guide wire to open the bone, for passing drill and guide wire of the lateral stop guide portion 13 there is a plurality of guide holes 14. このガイドホール14は方向性を出すため十分長い方がよいが、板に単に複数の穴がある構造でもよい。 This guide hole 14 is good enough longer order to give directionality, or a structure in which simply a plurality of holes in the plate.

【0013】図5で示す第2実施例はスクリュー等による横止め部を挿入するためのドリルやガイドワイヤが至適位置に挿入された時、このドリルやガイドワイヤ15 [0013] When the second embodiment shown in FIG. 5 the drill and guide wire for inserting the transverse stop portion by the screw or the like is inserted into the optimal position, the drill and guide wire 15
に取りつけることができる締結部16があるものである。 In which there is a fastening part 16 which can be attached to. 別の横止め用の穴17、18にドリルやガイドワイヤを通したい時、横止めガイド部19(これは横止めガイド部13と同一であってもよい)をを用いてドリルやガイドワイヤを通すが、この時横止めガイド部19は、 When you want through drill and guide wire into the hole 17, 18 for different lateral stop, the drill and guide wire with a lateral stop guide portion 19 (which may be the same as Yokotome guide portion 13) pass through, but this time Yoko stop guide unit 19,
連結部11とドリルやガイドワイヤ15との両端で架橋されるため、ドリルやガイドワイヤは穴17、18により容易に挿入可能になる。 Because it is cross-linked at both ends of the connecting portion 11 and the drill and guide wire 15, the drill and guide wire becomes easily inserted by holes 17, 18.

【0014】なお、本発明は上記した実施例に限定されるものではなく要旨の範囲内において各種の変形を採り得るものである。 [0014] Incidentally, the present invention can adopt various modifications within the scope of the gist is not limited to the aforementioned embodiments.

【0015】 [0015]

【発明の効果】上記した説明により明らかな様に、従来の髄内釘の横止めスクリューの髄外ガイドを用いたドリルやガイドワイヤの挿入は単数の挿入のため時間がかかることがあったのに比べ、本発明によれば複数の同時挿入ができることでより確率的に容易な挿入でき、従って短時間のレントゲン被爆の少ない横止め用スクリューの挿入が可能である。 As is apparent from the above description, according to the present invention, the drill and guide wire insertion with extramedullary guide transverse locking screws of a conventional intramedullary nail had to take time for insertion of the singular in comparison, according to the present invention can more stochastically easy insertion by can multiple simultaneous insertion of, thus allowing insertion of small transverse locking screw of short X-ray exposure. これによりレントゲン線被爆量が多いことによる生体毒性の問題はよりよい解決ができる。 Thus the biological toxicity by often Roentgen ray exposure amount problem can better solution.
