Abstract

SE PRESENTA UNA VALVULA ELASTOMERICA FLEXIBLE AUTOOBTURANTE. LA VALVULA SE PUEDE UTILIZAR PARA OBTURAR UN DISPOSITIVO DE TROCAR PARA HAYA PERDIDAS LA PRESION DEL GAS DURANTE UN PROCESO QUIRURGICO LAPAROSCOPICO CUANDO SE INSERTA UN INSTRUMENTO QUIRURGICO A SU TRAVES ASI COMO CUANDO NO SE INSERTA NINGUN INSTRUMENTO. LA VALVULA DE UNA SOLA PIEZA PREFERENTE INCLUYE UN REBORDE QUE TIENE UNA APERTURA Y UNA SECCION DE PARED CILINDRICA QUE SE EXTIENDE HASTA UN PAR DE SECCIONES DE PARED DE OBTURACION OPUESTAS ENTRE SI QUE DEFINEN UNA RANURA EN FORMA GENERALMENTE DE S. LA FORMA DE ESTA RANURA AL FINAL DE ESTAS SECCIONES DE PARED DEFINE LAS SUPERFICIES DE OBTURACION. EL REBORDE INCLUYE PREFERENTEMENTE UNA REGION EN FORMA DE BOVEDA CONCENTRICA A LA APERTURA DISPUESTA EN EL CENTRO. LA VALVULA TAMBIEN SE COMPONE PREFERENTEMENTE DE UN CAUCHO DE SILICONA. LA VALVULA PRESENTA LA VENTAJA DE QUE ES FACIL DE FABRICAR Y MONTAR Y QUE PUEDE PROPORCIONAR UNA OBTURACION ADECUADA CONTRA LA SUPERFICIE DE CUALQUIER INSTRUMENTO QUIRURGICO INSERTADO A SU TRAVES. ADEMAS, CON LA VALVULA MEJORADA SOLO REQUERIRA UNA PEQUEÑA CANTIDAD DE FUERZA PARA INSERTAR LOS INSTRUMENTOS Y RESISTIRA LA EVERSION DE LAS PAREDES DE LA VALVULA AL RETIRAR LOS INSTRUMENTOS. TAMBIEN SE PRESENTA UN CONJUNTO DE TROCAR QUE INCLUYE LA VALVULA OBTURADORA ARRIBA DESCRITA.
