Abstract
(EN)
A tibial osteotomy spreader according to the present invention comprises: a tip part which is inserted into an osteotomy site, and having one end of a first tip of a pair and one end of a second tip of the pair rotatably coupled to each other; a handle part detachably coupled to the other ends of the first tip and the second tip, and spacing apart, from each other, the other ends of the first tip and the second tip; and a fixing block inserted between the first tip and the second tip spaced apart by the handle part so as to maintain a spaced gap between the first tip and the second tip. The tibial osteotomy spreader according to the present invention can be separated from the handle part after the tip part is inserted into the osteotomy site, and thus it is easy to secure a space when a plate is fastened to the osteotomy site, and the present invention does not require a process of removing the spreader during the procedure, and thus the efficiency of the procedure can be improved. In addition, the fixing block is inserted between the first tip and the second tip to maintain a fracture gap while the tip part is inserted into the osteotomy site, and thus the accuracy of the procedure can be increased, and stability can be improved.

Un écarteur pour ostéotomie tibiale selon la présente invention comprend : une partie pointe qui est insérée dans un site d'ostéotomie, et ayant une extrémité d'une première pointe d'une paire et une extrémité d'une seconde pointe de la paire accouplées de manière rotative l'une à l'autre ; une partie poignée accouplée de façon détachable aux autres extrémités de la première pointe et de la seconde pointe, et espacées l'une de l'autre, les autres extrémités de la première pointe et de la seconde pointe ; et un bloc de fixation inséré entre la première pointe et la seconde pointe espacé de la partie poignée de façon à maintenir un espace entre la première pointe et la seconde pointe. L'écarteur pour ostéotomie tibiale selon la présente invention peut être séparé de la partie poignée après que la partie pointe soit insérée dans le site d'ostéotomie, et ainsi il est facile de fixer un espace lorsqu'une plaque est fixée au site d'ostéotomie, et la présente invention ne nécessite pas de processus de retrait de l'écarteur pendant l'intervention, et ainsi l'efficacité de l'intervention peut être améliorée. De plus, le bloc de fixation est inséré entre la première pointe et la seconde pointe pour maintenir un espace de fracture tandis que la partie pointe est insérée dans le site d'ostéotomie, et ainsi la précision de l'intervention peut être augmentée, et la stabilité peut être améliorée.
