Description
【考案の詳細な説明】
本考案は、骨折した骨を接続手術する際に用いられる鋼
線刺入案内装置に関するものである。[Detailed Description of the Invention] The present invention relates to a steel wire insertion guide device used when performing surgery to connect fractured bones.
骨折手術において、骨折部に鋼線を挿入して接続する手
術があるが、その為に骨折部に孔を明けるために鋼線を
刺入する必要がある。In bone fracture surgery, there is a surgery in which a steel wire is inserted and connected to the fractured part, but for this purpose it is necessary to insert the steel wire to make a hole in the fractured part.
しかし、その鋼線を目的の個所に一致するように刺入す
ることは困難である。However, it is difficult to insert the steel wire in the desired location.
そこで本考案は、鋼線を正確に目的の個所に刺入するこ
とのできる案内装置を提供せんとするものである。Therefore, the present invention aims to provide a guide device that can accurately insert a steel wire into a target location.
図面を参照して説明すると、第１図において、１はＬ形
の案内金具で、基部２の端部に球面内壁を有する椀状の
挿入案内部３が設けられ、そこより基部２を貫通する案
内孔４が設けられている。To explain with reference to the drawings, in Fig. 1, reference numeral 1 denotes an L-shaped guide fitting, and a bowl-shaped insertion guide part 3 having a spherical inner wall is provided at the end of the base 2, and the insertion guide part 3 penetrates the base 2 from there. A guide hole 4 is provided.
Ｌ形の支持部２ａには摺動可能に止金５が係合し該止金
は摺動面にスプリング板があり、任意の位置に止められ
るようになっている。A stop 5 is slidably engaged with the L-shaped support portion 2a, and the stop has a spring plate on its sliding surface so that it can be stopped at any position.
止金５には、指示針６がネジ７にて固定されている。An indicator needle 6 is fixed to the stopper 5 with a screw 7.
而して、該指示針６の先端が前記案内孔４の延長線に交
叉するように設けられている。The tip of the indicator needle 6 is provided so as to intersect with the extension line of the guide hole 4.
図において８，９は骨を示し、１０は骨８における骨折
部である。In the figure, numerals 8 and 9 indicate bones, and numeral 10 indicates a fracture in the bone 8.
このような骨折を接続する場合Ｉを鋼線刺入点とし、Ｏ
を鋼線の創出目標点として鋼線１１を刺入するのである
が、０点に指示針６の先端を合せ、ドリル１２により鋼
線を案内部３より案内孔４の案内によりＩ点より挿入す
れば、案内孔４の延長線がＯに一致しているので、鋼線
を０点より出すことができる。When connecting such fractures, use I as the steel wire insertion point, and O as the steel wire insertion point.
The steel wire 11 is inserted using the steel wire creation target point as shown in FIG. Then, since the extension line of the guide hole 4 coincides with O, the steel wire can be taken out from the zero point.
第２図の実施例は、創出目標点Ｏが軟部１３の内部にあ
って指示針の先端を合せることができない場合に用いら
れる装置で、前例の金具において、基部２に同様なＬ形
支持部２ｂが回転且固定可能に取付けられる指示針６，
６ａの延長上の交点が案内孔４の延長線に一致するよう
に設けられている。The embodiment shown in FIG. 2 is a device used when the creation target point O is inside the soft part 13 and the tip of the indicator needle cannot be aligned. an indicator needle 6 to which 2b is rotatably and fixably attached;
The intersection point on the extension of the guide hole 4 is provided so as to coincide with the extension line of the guide hole 4.
この装置では、指示針６，６ａの延長上の交点が骨１４
の創出目標点Ｏと推察される位置に一致するように器具
を保持し、鋼線を挿入することにより、刺入点Ｉより目
標点Ｏを通り、更に皮膚刺出点Ｏ′より出すことができ
る。In this device, the point of intersection of the extensions of the indicator needles 6, 6a is the bone 14.
By holding the instrument so that it coincides with the position estimated to be the target point O, and inserting the steel wire, it is possible to pass through the target point O from the insertion point I and then exit it from the skin puncture point O'. can.
以上で明かなように本考案によれば、骨折手術のための
鋼線刺入を、正確に行うことができ、しかも構造簡単で
、操作も容易である。As is clear from the above, according to the present invention, steel wire insertion for bone fracture surgery can be performed accurately, and the structure is simple and operation is easy.
