摘要：
The present invention relates to a rail-type retractor for minimal invasive surgery, comprising: a first blade having a curved shape a second blade having a curved shape a blade guide rail that includes two guide rails disposed parallel to each other, wherein the upper portion of the first blade is fixedly coupled to an inner coupling part after sliding along the inner surfaces of the two guide rails a second blade fixing means that fixedly couples the second blade to a coupling part in the center of the front thereof such that the second blade faces the first blade, slides the second blade along the inner surfaces of the two guide rails, and adjusts the distance from the first blade and a first coupling plate and a second coupling plate, wherein, while the first blade and the second blade are spaced apart from each other by the second blade fixing means, the first coupling plate is engaged with one end of the upper portion of the first blade and one end of the upper portion of the second blade and is sildably coupled therewith from top to bottom, and the second coupling plate is engaged with the other end of the upper portion of the first blade and the other end of the upper portion of the second blade and is sildably coupled therewith from top to bottom.La présente invention concerne un écarteur de type rail pour une chirurgie mini-invasive, comprenant : une première lame ayant une forme incurvée une seconde lame ayant une forme incurvée un rail de guidage de lame qui comprend deux rails de guidage disposés parallèlement lun à lautre, la partie supérieure de la première lame étant accouplée de façon fixe à une partie daccouplement interne après coulissement le long des surfaces internes des deux rails de guidage un second moyen de fixation de lame qui accouple de façon fixe la seconde lame à une partie daccouplement dans le centre de lavant de cette dernière de telle sorte que la seconde lame fait face à la première lame, coulisse la seconde lame le long des su
