好適と考える本発明の実施形態を、図面に基づいて本発明の作用を示して簡単に説明する。   Preferred embodiments of the present invention will be briefly described with reference to the drawings, showing the operation of the present invention.

例えば、腕9の橈骨遠位端の粉砕骨折を発症した際、該粉砕骨折によってバラバラに切離した骨4aに対し、一方向からピン3aを刺入する構成では、全ての切離した骨4aにピン3aを刺入することができない場合がある。   For example, when a crush fracture at the distal end of the radius of the arm 9 occurs, the pin 4a is inserted from one direction into the bone 4a cut apart by the crush fracture. 3a may not be able to be inserted.

この点、本発明は、切離した骨4aに放射状にピン3aを刺入できるから、様々な方向から切離した骨4aの夫々にピン3aを刺入し、更に、該ピン3aをピン支持部2aで支持することによって前記切離した骨4aの全てを固定することができ、よって、この切離した骨4aは良好に治癒することになる。   In this regard, according to the present invention, since the pin 3a can be radially inserted into the cut bone 4a, the pin 3a is inserted into each of the cut bones 4a from various directions, and the pin 3a is further inserted into the pin support 2a. Thus, all of the cut bone 4a can be fixed, and the cut bone 4a can be healed satisfactorily.

本発明の具体的な実施例1について図1〜4に基づいて説明する。   A first embodiment of the present invention will be described with reference to FIGS.

本実施例は、両端部若しくはその近傍にピン支持部2a・2bが夫々設けられ骨4a・4bに添設される添設部材1と、前記ピン支持部2a・2bに支持され且つ骨4a・4bに刺入されるピン3a・3bとから成り、切離した骨4aを治癒させる創外固定器であって、一方のピン支持部2aは、複数のピン3aを支持し且つ前記切離した骨4aを囲繞する構成であり、該ピン支持部2aにより支持されるピン3aは、切離した骨4aに放射状に刺入可能に構成されているものである。   In this embodiment, the pin support portions 2a and 2b are provided at both ends or in the vicinity thereof, and the additional member 1 is attached to the bones 4a and 4b. An external fixation device for healing the dissected bone 4a, the pins 3a being inserted into the bone 4a, and one of the pin support portions 2a supporting a plurality of the pins 3a and being separated from the dissected bone 4a. And the pin 3a supported by the pin supporting portion 2a is configured to be radially piercable into the cut bone 4a.

添設部材1は、棒ネジ状の第一添設部材11と、該第一添設部材11と螺合される筒状の第二添設部材12とから構成されている。第一添設部材11に対して第二添設部材12を回動せしめることで、該第一添設部材11から該第二添設部材12が突没し、これにより添設部材1を伸縮することができる。   The additional member 1 includes a rod-shaped first additional member 11 and a cylindrical second additional member 12 screwed to the first additional member 11. By rotating the second additional member 12 with respect to the first additional member 11, the second additional member 12 protrudes and retracts from the first additional member 11, thereby expanding and contracting the additional member 1. can do.

図中符号13は、第一添設部材11に対する第二添設部材12の不意の回動を阻止する為の止めネジである。   The reference numeral 13 in the figure denotes a set screw for preventing the second additional member 12 from rotating unexpectedly with respect to the first additional member 11.

前記ピン支持部2a・2bは、第一添設部材11及び第二添設部材12に夫々連設されている。   The pin support portions 2a and 2b are connected to the first additional member 11 and the second additional member 12, respectively.

第一添設部材11に連設されているピン支持部2a(以下、第一ピン支持部2aという。)は、添設部材1の延設方向と交叉する方向に延びる半環状ピン支持部が採用されている。   The pin support portion 2a (hereinafter, referred to as a first pin support portion 2a) connected to the first attachment member 11 has a semi-annular pin support portion extending in a direction intersecting the extending direction of the attachment member 1. Has been adopted.

この半環状ピン支持部は、骨折部位を囲繞できるよう形状、例えば、腕9の橈骨遠位端(手首付近)の粉砕骨折を治療する為に添設部材1を腕9に添設した際、該半環状ピン支持部が手首付近を囲繞できる形状のものが採用されている。   This semi-circular pin support portion is shaped so as to surround the fracture site, for example, when the additional member 1 is attached to the arm 9 to treat a crush fracture at the distal end of the radius of the arm 9 (near the wrist), The semi-circular pin support has a shape capable of surrounding the vicinity of the wrist.

尚、図面では、半環状ピン支持部としてく字状のものを図示したが、例えば、三日月状、Cリング状等、様々なものが採用可能である。   In the drawings, a rectangular shape is shown as the semi-circular pin support portion, but various shapes such as a crescent shape and a C-ring shape can be adopted.

第一ピン支持部2aとして、例えば、手首付近の全周囲を囲繞できる環状ピン支持部を採用しても良いが、この構成では、添設部材1を腕9に添設する際に手を環状ピン支持部に通さねばならず、この分だけ、添設作業が厄介となる。特に、膝等の骨折の際には、足を環状ピン支持部に通すことが大変厄介となる。   As the first pin support 2a, for example, an annular pin support that can surround the entire circumference near the wrist may be adopted. However, in this configuration, when the additional member 1 is attached to the arm 9, It has to be passed through the pin supporting portion, and the additional work becomes troublesome. In particular, in the case of a fracture such as a knee, it is very troublesome to pass the foot through the annular pin support.

半環状ピン支持部は二枚の半環状支持板5a・5bから成り、この二枚の半環状支持板5a・5b間に複数のピン3aを任意の間隔で挟持できるように構成されている。   The semi-circular pin support portion is composed of two semi-circular support plates 5a and 5b, and is configured such that a plurality of pins 3a can be sandwiched between the two semi-circular support plates 5a and 5b at an arbitrary interval.

この二枚の半環状支持板5a・5bは、調整ネジ6の操作によって間隔を広狭可能に構成されている。二枚の半環状支持板5a・5bの間隔を狭めれば、ピン3aの挟持が可能となり、また、該間隔を広げれば、ピン3aの挟持を解除することができる。   The two semi-annular support plates 5a and 5b are configured to be able to widen and narrow the interval by operating the adjustment screw 6. If the space between the two semi-annular support plates 5a and 5b is reduced, the pin 3a can be held, and if the space is widened, the pin 3a can be released.

調整ネジ6は、半環状ピン支持部の両端部の近傍と中央部との合計三カ所に設けられている。各調整ネジ6を夫々調整することにより、二枚の半環状支持板5a・5bの間隔を場所ごとに微調整でき、よって、全てのピン3aを良好な挟持圧によって支持することができる。   The adjusting screws 6 are provided at a total of three places: near the both ends of the semi-annular pin support and at the center. By adjusting each of the adjusting screws 6, the distance between the two semi-annular support plates 5a and 5b can be finely adjusted for each location, so that all the pins 3a can be supported by a good clamping pressure.

また、前記調整ネジ6が螺合するネジ孔27は、二枚の半環状支持板5a・5bの内の一方の半環状支持板5aにのみ設けられ、他方の半環状支持板5bには該調整ネジ6が貫通する貫通孔28のみが設けられている。この構成により、厄介な製造工程である前記ネジ孔27の穿設は、一方の半環状支持板5aに対してのみ行えば良いことになり、生産性が良好となる。   The screw hole 27 into which the adjusting screw 6 is screwed is provided only on one of the two semi-annular support plates 5a and 5b, and the other semi-annular support plate 5b has the screw hole 27. Only a through hole 28 through which the adjusting screw 6 passes is provided. With this configuration, it is only necessary to perform the drilling of the screw hole 27, which is a troublesome manufacturing process, on only one of the semi-annular support plates 5a, and the productivity is improved.

また、二枚の半環状支持板5a・5bの対向内面には、摩擦部7(具体的には微細凹凸)が夫々設けられている。この摩擦部7の存在により、二枚の半環状支持板5a・5bはピン3aを極めて良好に支持することができる。   Further, friction portions 7 (specifically, fine irregularities) are provided on the opposed inner surfaces of the two semi-annular support plates 5a and 5b, respectively. Due to the presence of the friction portion 7, the two semi-annular support plates 5a and 5b can support the pin 3a very well.

この第一ピン支持部2aと前記第一添設部材11とは、該第一添設部材11に対して該第一ピン支持部2aが屈曲及び旋回動できるように連設されている。   The first pin supporting portion 2a and the first additional member 11 are connected to each other so that the first pin supporting portion 2a can bend and pivot with respect to the first additional member 11.

また、第一ピン支持部2aは第一添設部材11に着脱自在に連設されている。   The first pin support 2a is detachably connected to the first attached member 11.

具体的には、第一添設部材11の端部には球部14が設けられ、この球部14が第一ピン支持部2aの中央部に当接し、該球部14は該第一ピン支持部2aと挟持板15とによって挟持されている。挟持板15は、中央部には前記第一添設部材11が挿通される挿通孔16と前記球部14に当接する当接部17とが設けられ、左右部にはネジ貫通孔18a・18bが夫々設けられている。第一ピン支持部2aにして前記ネジ貫通孔18a・18bと対応する位置にはネジ孔19a・19bが設けられている。   Specifically, a ball portion 14 is provided at an end of the first attached member 11, and the ball portion 14 contacts the central portion of the first pin support portion 2a. It is clamped by the support portion 2a and the clamping plate 15. The holding plate 15 is provided with an insertion hole 16 through which the first additional member 11 is inserted and a contact portion 17 that comes into contact with the ball portion 14 at a central portion, and screw through holes 18a and 18b at left and right portions. Are provided respectively. Screw holes 19a and 19b are provided at positions corresponding to the screw through holes 18a and 18b in the first pin support 2a.

第一添設部材11の球部14を第一ピン支持部2aと挟持板15とによって挟持せしめ、挟持板15側から、頭部20にネジ部21が設けられた構成の止着ネジ22を前記挟持板15のネジ貫通孔18a・18bに夫々貫通せしめ、該止着ネジ22のネジ部21を前記第一ピン支持部2aのネジ孔19a・19bに夫々螺合せしめると、止着ネジ22の頭部20が前記挟持板15を前記第一ピン支持部2a側に押圧し、これにより該挟持板15と該第一ピン支持部2aとが前記第一添設部材11の球部14を挟持する。   The ball portion 14 of the first additional member 11 is clamped between the first pin supporting portion 2a and the clamping plate 15, and a fastening screw 22 having a screw portion 21 provided on the head 20 from the clamping plate 15 side. When the screw portion 21 of the fixing screw 22 is screwed into the screw hole 19a, 19b of the first pin support portion 2a, the screw is inserted into the screw through hole 18a, 18b of the holding plate 15. Presses the holding plate 15 toward the first pin support portion 2a, whereby the holding plate 15 and the first pin support portion 2a push the ball portion 14 of the first additional member 11 Pinch.

止着ネジ22を弛めれば、前記挟持板15と前記第一ピン支持部2aとの挟持作用が低下し、該第一ピン支持部2aは、前記球部14を支点に傾動したり旋回動したりすることができる。   If the fastening screw 22 is loosened, the clamping action between the clamping plate 15 and the first pin support 2a is reduced, and the first pin support 2a tilts or pivots around the ball 14 as a fulcrum. You can move.

即ち、この第一ピン支持部2aの傾動及び旋回動により、該第一ピン支持部2aは第一添設部材11に対して屈曲及び旋回動できることになる。   That is, due to the tilting and turning movement of the first pin supporting portion 2a, the first pin supporting portion 2a can bend and turn with respect to the first attached member 11.

また、この構成により、止着ネジ21を弛めて挟持板15を除去することにより、第一ピン支持部2aと第一添設部材11との連設を解除し、第一ピン支持部2aを別の構成の第一ピン支持部2aに取り替えることも可能となる。   Further, according to this configuration, the connection between the first pin supporting portion 2a and the first attached member 11 is released by loosening the fastening screw 21 and removing the holding plate 15, and the first pin supporting portion 2a Can be replaced with the first pin support 2a having another configuration.

一方、第二添設部材12に連設されているピン支持部2b(以下、第二ピン支持部2bという。)は、添設部材1の延設方向に延びる板状ピン支持部が採用されている。   On the other hand, as the pin support portion 2b (hereinafter, referred to as a second pin support portion 2b) connected to the second additional member 12, a plate-like pin support portion extending in the extending direction of the additional member 1 is employed. ing.

板状ピン支持部は、二枚の板状支持体8a・8bから成り、この二枚の板状支持体8a・8bに複数のピン3bを挟持できるように構成されている。   The plate-shaped pin support portion includes two plate-shaped supports 8a and 8b, and is configured so that a plurality of pins 3b can be held between the two plate-shaped supports 8a and 8b.

この二枚の板状支持体8a・8bは調整ネジ30の操作によって間隔を広狭可能に構成されている。二枚の板状支持体8a・8bの間隔を狭めれば、ピン3bの挟持が可能となり、また、該間隔を広げれば、ピン3bの挟持を解除することができる。   The two plate-shaped supports 8a and 8b are configured to be able to be widened and narrowed by operating the adjusting screw 30. If the distance between the two plate-like supports 8a and 8b is reduced, the pin 3b can be held, and if the distance is widened, the pin 3b can be released.

また、前記調整ネジ30が螺合するネジ孔31は、二枚の板状支持体8a・8bの内の一方の板状支持体8aにのみ設けられ、他方の板状支持体8a・8bには該調整ネジ30が貫通する貫通孔32のみが設けられている。この構成により、厄介な製造工程である前記ネジ孔31の穿設は、一方の板状支持体8aに対してのみ行えば良いことになり、生産性が良好となる。   The screw hole 31 into which the adjusting screw 30 is screwed is provided only in one of the two plate-like supports 8a and 8b, and is provided in the other plate-like supports 8a and 8b. Has only a through hole 32 through which the adjusting screw 30 passes. With this configuration, it is only necessary to perform the drilling of the screw hole 31 which is a troublesome manufacturing process on only one of the plate-like supports 8a, and the productivity is improved.

また、二枚の板状支持体8a・8bの対向内面には、前記ピン3bを保持する保持凹部33が夫々設けられている。この保持凹部33の存在により、二枚の板状支持体8a・8bはピン3bを極めて良好に支持することができる。   In addition, holding recesses 33 for holding the pins 3b are respectively provided on opposed inner surfaces of the two plate-like supports 8a and 8b. Due to the presence of the holding recess 33, the two plate-like supports 8a and 8b can support the pin 3b extremely well.

尚、図面は、直線状の保持凹部33が添設部材1の延設方向に所定間隔を置いて二箇所設けられている場合を図示しているが、この保持凹部33の数は保持したいピン3bの数によって適宜選択され、また、この保持凹部33の内面にも摩擦部(微細凹凸)を設けても良い。   Although the drawings show a case where two linear holding recesses 33 are provided at predetermined intervals in the extending direction of the auxiliary member 1, the number of the holding recesses 33 is the number of pins to be held. A friction portion (fine unevenness) may be provided on the inner surface of the holding concave portion 33 as appropriate, depending on the number of 3b.

この第二ピン支持部2bと前記第二添設部材12とは、前記第一ピン支持部2aと前記第一添設部材11との連設と同様、該第二添設部材12に対して該第二ピン支持部2bが屈曲及び旋回動できるように連設されている。   The second pin support 2b and the second additional member 12 are connected to the second additional member 12 similarly to the connection of the first pin support 2a and the first additional member 11. The second pin support portion 2b is connected so as to be able to bend and pivot.

また、第二ピン支持部2bは第二添設部材12に着脱自在に連設されている。   Further, the second pin support 2b is detachably connected to the second auxiliary member 12.

具体的には、第二添設部材12の端部には球部34が設けられ、この球部34が前記二枚の板状支持体8a・8bの内の一方の板状支持体8aと挟持板35とによって挟持されている。挟持板35は、中央部には前記球部34に当接する当接部(図示省略)が設けられ、左右部(図2中の上下部)にはネジ貫通孔38a・38bが夫々設けられている。前記一方の板状支持体8aにして前記挟持板35の当接部と対応する位置には当接凹部36が設けられ、該一方の板状支持体8aにして前記挟持板35のネジ貫通孔38a・38bと対応する位置にはネジ孔39a・39bが設けられている。   Specifically, a sphere portion 34 is provided at an end of the second additional member 12, and the sphere portion 34 is connected to one of the two plate-like supports 8a and 8b. It is held by the holding plate 35. The holding plate 35 is provided with a contact portion (not shown) for contacting the ball portion 34 at a center portion, and screw through holes 38a and 38b at left and right portions (upper and lower portions in FIG. 2). I have. A contact recess 36 is provided at a position corresponding to the contact portion of the holding plate 35 on the one plate-shaped support 8a, and a screw through hole of the holding plate 35 is formed on the one plate-shaped support 8a. Screw holes 39a and 39b are provided at positions corresponding to 38a and 38b.

第二添設部材12の球部34を前記一方の板状支持体8aと前記と挟持板35とによって挟持せしめ、挟持板35側から、頭部40にネジ部41が設けられた構成の止着ネジ42を前記挟持板35のネジ貫通孔38a・38bに夫々貫通せしめ、該止着ネジ42のネジ部41を前記一方の板状支持体8aのネジ孔39a・39bに夫々螺合せしめると、止着ネジ42の頭部40が前記挟持板35を前記一方の板状支持体8a側に押圧し、これにより該挟持板35と該一方の板状支持体8aとが前記第二添設部材12の球部34を挟持する。   The ball portion 34 of the second additional member 12 is clamped by the one plate-like support 8a and the clamping plate 35, and the screw 40 is provided on the head 40 from the clamping plate 35 side. When the fixing screw 42 is passed through the screw through holes 38a and 38b of the holding plate 35, and the screw portion 41 of the fixing screw 42 is screwed into the screw holes 39a and 39b of the one plate-like support 8a. The head 40 of the fastening screw 42 presses the holding plate 35 toward the one plate-shaped support 8a, whereby the holding plate 35 and the one plate-shaped support 8a are attached to the second attached plate 8a. The spherical portion 34 of the member 12 is held.

止着ネジ42を弛めれば、前記挟持板35と前記一方の板状支持体8aとの挟持作用が低下し、第二ピン支持部2bは、前記球部34を支点に傾動したり旋回動したりすることができる。   If the fastening screw 42 is loosened, the holding action between the holding plate 35 and the one plate-shaped support 8a is reduced, and the second pin support 2b tilts or pivots around the ball 34 as a fulcrum. You can move.

即ち、この第二ピン支持部2bの傾動及び旋回動により、該第二ピン支持部2bは第二添設部材12に対して屈曲及び旋回動できることになる。   That is, due to the tilting and turning movement of the second pin supporting portion 2b, the second pin supporting portion 2b can bend and turn with respect to the second attached member 12.

また、この構成により、止着ネジ42を弛めて挟持板35を除去することにより、第二ピン支持部2bと第二添設部材12との連設を解除し、第二ピン支持部2bを別の構成の第二ピン支持部2bに取り替えることも可能となる。   Further, according to this configuration, the connection between the second pin supporting portion 2b and the second attached member 12 is released by loosening the fastening screw 42 and removing the holding plate 35, and the second pin supporting portion 2b Can be replaced with the second pin support 2b of another configuration.

本実施例の調整ネジ6,止めネジ13,止着ネジ22,調整ネジ30,止着ネジ42等、全てのネジは、同一の工具(例えば六角レンチ)によって螺動操作できるものが採用されている。   All the screws such as the adjusting screw 6, the set screw 13, the fixing screw 22, the adjusting screw 30, the fixing screw 42, and the like of this embodiment are those that can be screw-operated by the same tool (for example, a hexagon wrench). I have.

本実施例は、特に手首付近、具体的には腕9の橈骨遠位端の粉砕骨折を発症した際の治療に使用するもので、以下、その使用方法を説明する。   The present embodiment is used particularly for the treatment of the occurrence of a crush fracture near the wrist, specifically, at the distal end of the radius of the arm 9, and the method of use will be described below.

先ず、骨折により多数の小片状に切離した骨4aの全てにピン3aを夫々刺入する。この際、一方向からピン3aを夫々刺入するだけでは全ての切離した骨4aに刺入することができず、該ピン3aを所定間隔を置いた放射状とすることで全ての切離した骨4aへの刺入が可能となる(図4参照)。   First, the pins 3a are respectively inserted into all of the bones 4a cut into many small pieces due to the fracture. At this time, it is not possible to pierce all the cut bones 4a only by inserting the pins 3a from one direction, and all the cut bones 4a are formed by forming the pins 3a radially at predetermined intervals. Can be inserted (see FIG. 4).

また、切離した骨4aを良好に固定する為、該切離した骨4aの近傍の骨4b、具体的には橈骨の骨折していない部分にもピン3bを刺入する。   Further, in order to properly fix the cut bone 4a, the pin 3b is also inserted into the bone 4b near the cut bone 4a, specifically, a portion of the radius that is not fractured.

続いて、添設部材1を腕9の近傍に位置せしめ、第一ピン支持部2aで前記切離した骨4aに刺入したピン3aを支持し、第二ピン支持部2bで前記橈骨に刺入したピン3bを支持する。   Then, the attachment member 1 is positioned near the arm 9, the first pin support 2a supports the pin 3a inserted into the cut bone 4a, and the second pin support 2b inserts the pin into the radius. The supported pin 3b is supported.

この際、第一ピン支持部2aは、二枚の半環状支持板5a・5bから成る構成が採用されているから、前記所定間隔を置いて放射状となっている複数のピン3aの全てを良好に挟持して支持することができる。   At this time, since the first pin supporting portion 2a adopts a configuration including two semi-annular supporting plates 5a and 5b, all of the plurality of pins 3a radially arranged at the predetermined interval are satisfactorily removed. And can be supported.

また、当然ながら第二ピン支持部2bも、前記橈骨に刺入したピン3bの全てを良好に挟持して支持することができる。   In addition, as a matter of course, the second pin support 2b can also satisfactorily pinch and support all the pins 3b inserted into the radius.

また、第一ピン支持部2aで支持するピン3aの並設方向と第二ピン支持部2bで支持するピン3bの並設方向とに合わせて、添設部材1に対して第一ピン支持部2aや第二ピン支持部2bを屈曲若しくは旋回動することにより、やはり全てのピン3a・3bを良好に挟持して支持することができる。   In addition, the first pin support portion with respect to the additional member 1 is adjusted in accordance with the direction in which the pins 3a supported by the first pin support portion 2a are arranged side by side and the direction in which the pins 3b supported by the second pin support portion 2b are arranged side by side. By bending or turning the second pin support portion 2a or the second pin support portion 2b, all the pins 3a and 3b can be satisfactorily pinched and supported.

また、第一添設部材11や第二添設部材12を回動させることによっても、第一ピン支持部2aや第二ピン支持部2bを骨4a・4bに刺入したピン3a・3bの位置に合わせることができ、よって、該ピン3a・3bを良好に挟持して支持することができる。   Also, by rotating the first additional member 11 and the second additional member 12, the pins 3a and 3b that have inserted the first pin support 2a and the second pin support 2b into the bones 4a and 4b can be formed. The pins 3a and 3b can be satisfactorily pinched and supported.

また、添設部材1の伸縮によっても、第一ピン支持部2aや第二ピン支持部2bを骨4a・4bに刺入したピン3a・3bの位置に合わせることができる。   Also, the first pin support 2a and the second pin support 2b can be adjusted to the positions of the pins 3a and 3b inserted into the bones 4a and 4b by the expansion and contraction of the attached member 1.

尚、本実施例は、橈骨遠位端の粉砕骨折を発症した際、該粉砕骨折によって切離した骨4aとその他の橈骨4bとにのみピン3a・3bを刺入する構成の為、骨折の治癒がある程度完了した後、該ピン3a・3bによって切離した骨4aを固定したまま、手首の屈伸や指を使用した仕事等のリハビリを行うことができる。即ち、骨折の治療を続けながら、リハビリを行うことができる。   In the present embodiment, when a fracture at the distal end of the radius occurs, the pins 3a and 3b are inserted only into the bone 4a separated by the fracture and the other radius 4b. After a certain degree of completion, rehabilitation such as bending and stretching of the wrist and work using fingers can be performed while the cut bone 4a is fixed by the pins 3a and 3b. That is, rehabilitation can be performed while continuing treatment for the fracture.

また、骨折の治癒がある程度完了した段階からリハビリを開始できる為、治癒を行う際に手首等を全く動かさない期間が短く、よって、手首や指の筋肉の衰えは少なく、リハビリ期間を短縮することができる。   In addition, since rehabilitation can be started from the stage where the healing of the fracture has been completed to a certain extent, the period during which the wrist etc. is not moved at all during the healing is short, so the muscles of the wrists and fingers are less weak, and the rehabilitation period is shortened Can be.

骨折が完全に治癒した後、骨4a・4bからピン3a・3bを抜く。   After the fracture is completely healed, the pins 3a and 3b are removed from the bones 4a and 4b.

本実施例は上述のように構成したから、一方向からピン3aを刺入するだけでは全ての切離した骨4aに該ピン3aを刺入できないような骨折でも、放射状にピン3aを配設することで該全ての切離した骨4aにピン3aを刺入し、該ピン3aを一個の創外固定器で全て固定して治癒を良好に達成できる実用性に秀れた創外固定器となる。   Since the present embodiment is configured as described above, the pins 3a are arranged radially even in a fracture in which the pins 3a cannot be inserted into all the cut bones 4a by merely inserting the pins 3a from one direction. As a result, the pin 3a is inserted into all the dissected bones 4a, and the pin 3a is fixed with one external fixator, so that an external fixator with excellent practicality can be achieved with good healing. .

また、第一ピン支持部2aは、放射状に配設されたピン3aを任意の間隔で支持できるから、切離した骨4aの状態に応じてピン3aを最適な状態に刺入し、且つ、該骨4aを固定して治癒を行うことができる。   Further, since the first pin support 2a can support the pins 3a arranged radially at an arbitrary interval, the first pin support 2a inserts the pin 3a in an optimal state according to the state of the cut bone 4a, and Healing can be performed by fixing the bone 4a.

また、第一ピン支持部2aは添設部材1に対して屈曲したり旋回動したりできるから、この点においても切離した骨4aの状態に応じてピン3aを最適な状態に刺入し、且つ、該骨4aを固定して治癒を行うことができる。   In addition, since the first pin supporting portion 2a can bend or pivot with respect to the auxiliary member 1, the pin 3a is inserted into an optimal state according to the state of the separated bone 4a also at this point, In addition, the bone 4a can be fixed for healing.

また、第二ピン支持部2bも添設部材1に対して屈曲したり旋回動したりできるから、この点においても切離した骨4aの状態に応じてピン3bを最適な状態に刺入し、且つ、該骨4bや切離した骨4aを固定して治癒を行うことができる。   In addition, since the second pin support portion 2b can also bend or pivot with respect to the auxiliary member 1, the pin 3b is inserted into an optimal state in this point according to the state of the cut bone 4a. In addition, the bone 4b and the cut bone 4a can be fixed and healed.

また、添設部材1は伸縮自在であるから、この点においても切離した骨4aや該切離した骨4aを固定する為の骨4bの状態に応じてピン3a・3bを最適な状態に刺入し、且つ、固定して治癒を行うことができる。   In addition, since the additional member 1 is expandable and contractable, the pins 3a and 3b are inserted into the optimum state in this point in accordance with the state of the cut bone 4a and the state of the bone 4b for fixing the cut bone 4a. And can be fixed and healed.

また、第一ピン支持部2aは半環状ピン支持部が採用されているから、手首等に被嵌する作業で該半環状ピン支持部を簡単に骨折部位の周囲に配設することができ、よって、ピン3a・3bの支持作業を容易に行うことができる。   In addition, since the first pin supporting portion 2a employs a semi-circular pin supporting portion, the semi-circular pin supporting portion can be easily disposed around the fracture site by a work to be fitted on a wrist or the like, Therefore, the operation of supporting the pins 3a and 3b can be easily performed.

尚、本実施例は、特に腕9の橈骨遠位端の粉砕骨折を治療する場合について説明したが、例えば、膝,肘等、他の骨折を治癒する場合にも採用することができる。   Although the present embodiment has been described in particular for the case of treating a crushed fracture at the distal end of the radius of the arm 9, the present invention can also be applied to the case of healing other fractures such as a knee and an elbow.

本発明の具体的な実施例2について図5,6に基づいて説明する。   A second embodiment of the present invention will be described with reference to FIGS.

本実施例は、両端部若しくはその近傍にピン支持部80b・80cが、また、中程にはピン支持部80aが設けられ、ピン支持部80aとピン支持部80bの間及びピン支持部80aとピン支持部80cの間に夫々、骨4a・4b・4cに添設される添設部材1及び添設部材50が設けられ、前記ピン支持部80a・80b・80cには骨4a・4b・4cに刺入されるピン90a・90b・90cが設けられ、切離した骨4aを治癒させる創外固定器であって、中程のピン支持部80aは、複数のピン90aを支持し且つ前記切離した骨4aを囲繞する構成であり、該ピン支持部80aにより支持されるピン90aは、切離した骨4aに放射状に刺入可能に構成されているものである。   In the present embodiment, pin support portions 80b and 80c are provided at both ends or in the vicinity thereof, and a pin support portion 80a is provided in the middle, between the pin support portion 80a and the pin support portion 80b and between the pin support portions 80a. An auxiliary member 1 and an auxiliary member 50 are provided between the pin supporting portions 80c, respectively, which are provided to the bones 4a, 4b, and 4c, respectively. The bones 4a, 4b, and 4c are provided on the pin supporting portions 80a, 80b, and 80c, respectively. An external fixator provided with pins 90a, 90b, and 90c to be inserted into the external fixation device for healing the dissected bone 4a, wherein a middle pin support portion 80a supports a plurality of pins 90a and separates the dissociated bone 4a. The pin 90a, which surrounds the bone 4a and is supported by the pin support portion 80a, is configured to be able to radially penetrate the cut bone 4a.

添設部材1は、棒ネジ状の第一添設部材81及び第三添設部材51と、該第一添設部材81及び第三添設部材51と螺合される筒状の第二添設部材82とから構成されている。第一添設部材81及び第三添設部材51に対して第二添設部材82を回動せしめることで、該第二添設部材82の両端部から該第一添設部材81及び第三添設部材51が突没し、これにより添設部材1を伸縮することができる。   The additional member 1 includes a rod-shaped first additional member 81 and a third additional member 51, and a cylindrical second additional member 81 screwed with the first additional member 81 and the third additional member 51. And the installation member 82. By rotating the second additional member 82 with respect to the first additional member 81 and the third additional member 51, the first additional member 81 and the third additional member 82 are moved from both ends of the second additional member 82. The additional member 51 protrudes and retracts, whereby the additional member 1 can expand and contract.

前記ピン支持部80a・80bは、第一添設部材81及び第三添設部材51に夫々連設されている。   The pin support portions 80a and 80b are connected to the first additional member 81 and the third additional member 51, respectively.

第一添設部材81に連設されているピン支持部80a(以下、第一ピン支持部80aという。)は、添設部材1の延設方向と交叉する方向に延びる半環状ピン支持部が採用されている。   The pin support portion 80a (hereinafter, referred to as a first pin support portion 80a) connected to the first attachment member 81 has a semi-annular pin support portion extending in a direction crossing the extending direction of the attachment member 1. Has been adopted.

この半環状ピン支持部は、骨折部位を囲繞できるよう形状、例えば、腕9の橈骨遠位端(手首付近)の粉砕骨折を治療する為に添設部材1を腕9に添設した際、該半環状ピン支持部が手首付近を囲繞できる形状のものが採用されている。   This semi-circular pin support portion is shaped so as to surround the fracture site, for example, when the additional member 1 is attached to the arm 9 to treat a crush fracture at the distal end of the radius of the arm 9 (near the wrist), The semi-circular pin support has a shape capable of surrounding the vicinity of the wrist.

尚、図面では、半環状ピン支持部としてく字状のものを図示したが、例えば、三日月状、Cリング状等、様々なものが採用可能である。   In the drawings, a rectangular shape is shown as the semi-circular pin support portion, but various shapes such as a crescent shape and a C-ring shape can be adopted.

第一ピン支持部80aとして、例えば、手首付近の全周囲を囲繞できる環状ピン支持部を採用しても良いが、この構成では、添設部材1を腕9に添設する際に手を環状ピン支持部に通さねばならず、この分だけ、添設作業が厄介となる。特に、膝等の骨折の際には、足を環状ピン支持部に通すことが大変厄介となる。   As the first pin support portion 80a, for example, an annular pin support portion that can surround the entire circumference near the wrist may be adopted. However, in this configuration, when the additional member 1 is attached to the arm 9, It has to be passed through the pin supporting portion, and the additional work becomes troublesome. In particular, in the case of a fracture such as a knee, it is very troublesome to pass the foot through the annular pin support.

半環状ピン支持部は二枚の半環状支持板83a・83bから成り、この二枚の半環状支持板83a・83b間に複数のピン90aを任意の間隔で挟持できるように構成されている。   The semi-circular pin support portion is composed of two semi-circular support plates 83a and 83b, and is configured such that a plurality of pins 90a can be held between the two semi-circular support plates 83a and 83b at arbitrary intervals.

この二枚の半環状支持板83a・83bは、調整ネジ84の操作によって間隔を広狭可能に構成されている。二枚の半環状支持板83a・83bの間隔を狭めれば、ピン90aの挟持が可能となり、また、該間隔を広げれば、ピン90aの挟持を解除することができる。   The two semi-annular support plates 83a and 83b can be widened or narrowed by operating the adjusting screw 84. If the distance between the two semi-annular support plates 83a and 83b is reduced, the pin 90a can be held, and if the distance is widened, the pin 90a can be released.

調整ネジ84は、半環状ピン支持部の両端部の近傍の合計二カ所に設けられている。各調整ネジ84を夫々調整することにより、二枚の半環状支持板83a・83bの間隔を場所ごとに微調整でき、よって、全てのピン90aを良好な挟持圧によって支持することができる。   Adjustment screws 84 are provided at a total of two locations near both ends of the semi-annular pin support. By adjusting each of the adjusting screws 84, the interval between the two semi-annular support plates 83a and 83b can be finely adjusted for each location, so that all the pins 90a can be supported by a good clamping pressure.

また、前記調整ネジ84が螺合するネジ孔85は、二枚の半環状支持板83a・83bの内の一方の半環状支持板83aにのみ設けられ、他方の半環状支持板83bには該調整ネジ84が貫通する貫通孔86のみが設けられている。この構成により、厄介な製造工程である前記ネジ孔85の穿設は、一方の半環状支持板83aに対してのみ行えば良いことになり、生産性が良好となる。   The screw hole 85 into which the adjustment screw 84 is screwed is provided only in one of the two semi-annular support plates 83a and 83b, and the other semi-annular support plate 83b has Only a through hole 86 through which the adjusting screw 84 passes is provided. With this configuration, the screw hole 85, which is a troublesome manufacturing process, needs to be formed only on one of the semi-annular support plates 83a, and the productivity is improved.

また、二枚の半環状支持板83a・83bの対向内面には、摩擦部87(具体的には微細凹凸)が夫々設けられている。この摩擦部87の存在により、二枚の半環状支持板83a・83bはピン90aを極めて良好に支持することができる。   In addition, friction portions 87 (specifically, fine irregularities) are provided on the opposed inner surfaces of the two semi-annular support plates 83a and 83b, respectively. Due to the presence of the friction portion 87, the two semi-annular support plates 83a and 83b can support the pin 90a extremely well.

この第一ピン支持部80aと前記第一添設部材81とは、該第一添設部材81に対して該第一ピン支持部80aが屈曲及び旋回動できるように連設されている。   The first pin support portion 80a and the first additional member 81 are connected to each other so that the first pin support portion 80a can bend and pivot with respect to the first additional member 81.

また、第一ピン支持部80aは第一添設部材81に着脱自在に連設されている。   The first pin support portion 80a is detachably connected to the first attachment member 81.
