GUIA DE CORTE FEMORAL DISTAL

APARATO EN BLOQUE DE CORTE FEMORAL DISTAL (10) PARA CIRUGIA DE LA RODILLA QUE CONSTA DE UN CUERPO (12) QUE GENERALMENTE TIENE SUPERFICIES PARALELAS PLANAS OPUESTAS Y NUMEROSAS SUPERFICIES PERIFERICAS PLANAS FORMAN UN CUERPO GENERALMENTE RECTANGULAR (12). UNA RANURA TRANSVERSAL (18) MOVIL CONTIENE UN MODULO VALGO (30) QUE CONTIENE UN MANGUITO TUBULAR (36) CON UN PAR DE CARAS OPUESTAS QUE APOYAN EL CUERPO EN LA RANURA (18). UNA PARTE DEL MANGUITO TUBULAR (36) SE ENROSCA Y DICHA PARTE ENRSCADA SE ALEJA DEL CUERPO (12). UN ORIFICIO ABIERTO EN EL EXTREMO (49) SE EXTIENDE A TRAVES DEL ELEMENTO TUBULAR (36). EL CUERPO (12) POSEE RANURAS DIAGONALES (24, 26) QUE SE EMPLEAN PARA REALIZAR CORTES BISELADOS EN UNA SUPERFICIE FEMORAL DISTAL ASI COMO RANURAS ANTERIORES Y POSTERIORES (20,22) PARA REALIZAR CORTES ANTERIORES Y POSTERIORES. EL ORIFICIO (49) DEL MANGUITO TUBULAR (36) ALBERGA UNA VARILLA INTRAMEDULAR (35). A distal femoral cutting block apparatus for use in knee surgery includes an instrument body that has generally flat opposing parallel surfaces and a plurality flat peripheral surfaces to form a generally rectangular body. The body provides anterior and posterior surfaces and medial and lateral surfaces. The transverse slot carries a valgus module that is movably disposed in the slot. The valgus module includes a tubular sleeve member having a pair of opposed sides that abut the body at the slot. A portion of the tubular sleeve member is threaded and the threaded portion extends away from the body. An open ended bore extends through the tubular member. The open ended bore of the tubular sleeve member of the module accommodates an intramedullary rod that fits the patient s intramedullary canal. A lock nut engages the threaded section of the module for locking the module in a desired position on the cutting block body by engaging the threaded portion and the instrument body to rigidly affix them together.
