Abstract

Dans la présente invention, une zone entre une partie cylindrique (11) et une découpe (25) formée dans un couvercle (23) d'un projecteur médical (18) est formée de manière à être le même espace que l'intérieur du couvercle (23). Cette partie espace partagé est utilisée pour évacuer de manière fiable de la chaleur et de l'air N depuis l'intérieur du projecteur médical (18) vers l'extérieur par l'intermédiaire d'un bras de retenue (9). De plus, un bras de support 6 est disposé avec une forme de tuyau pour permettre à l'air (N) d'être évacué vers une position séparée du projecteur médical (18).
