Title
(EN) INTRAMEDULLARY CANNULATED GUIDE FOR FRACTURE REDUCTION WITH ENDOSCOPIC CAMERA
(FR) GUIDE CANULÉ INTRAMÉDULLAIRE POUR RÉDUCTION DE FRACTURE AVEC CAMÉRA ENDOSCOPIQUE
Abstract
(EN)
The invention consists in a product for the closed reduction and, more specifically, in a new type of an intramedullary cannulated guide for fracture reduction with an endoscopic camera for use in intramedullary nailing surgeries. The intramedullary cannulated guide for fracture reduction is consisted of a flexible, unbreakable, modular and cannulated shaft, a T-handle with a hole in the upper surface, a camera, which is located at the edge of the guide, bears a lightning source and is connected wired or wireless to an image reproduction device, a sealing flange with a slot or spout, an input/output cannula for liquid suction and/or washing of the camera glass. The intramedullary cannulated guide for fracture reduction with an endoscopic camera is inserted in a bone that has suffered a fracture. The intramedullary image that the camera transmits, when it encounters the fracture point, is shown on the screen. Thus, the surgeon perceives the direction towards which the bone parts have to be pushed, in order to achieve their reduction with skeletal manipulations. After the intramedullary cannulated guide for fracture reduction is inserted, the camera is removed from the guide, by pulling out the cable of the camera, and, through the canal of the guide, the ball tip guide wire is inserted and the surgery continues as it is conducted up until today.

L'invention consiste en un produit pour la réduction à foyer fermé et, plus spécifiquement, en un nouveau type de guide canulé intramédullaire pour réduction de fracture avec caméra endoscopique s'utilisant dans le cadre d'interventions chirurgicales avec enclouage centromédullaire. Le guide canulé intramédullaire pour réduction de fracture est constitué d'une tige flexible, incassable, modulaire et canulée, d'une poignée en T avec un trou dans la surface supérieure, d'une caméra qui est située au bord du guide, porte une source de lumière et est connectée de manière filaire ou sans fil à un dispositif de reproduction d'image, d'une bride d'étanchéité avec une fente ou un élément d'écoulement, d'une canule d'entrée/sortie pour l'aspiration de liquide et/ou le lavage du verre de la caméra. Le guide canulé intramédullaire pour réduction de fracture avec caméra endoscopique est inséré dans un os fracturé. L'image intramédullaire que la caméra transmet lorsqu'elle rencontre le point de fracture est affichée à l'écran. Ainsi, le chirurgien perçoit la direction vers laquelle les parties osseuses doivent être poussées, afin d'obtenir leur réduction par des manipulations du squelette. Une fois que le guide canulé intramédullaire pour réduction de fracture est inséré, la caméra est retirée du guide en tirant le câble de la caméra, le fil-guide à extrémité sphérique est inséré à travers le canal du guide et l'intervention chirurgicale est poursuivie selon la méthode actuelle.
