ABSTRACT:
A fibre-optic laryngoscope spatula (1) having a light-exiting first end and an opposite second end and comprising a base part (1) and an exchangeable light-guide part (8) having a first spring-loaded coupling member (14). The base part (1) and the light-guide part (8) are designed to fit precisely together in such a way that the light-guide part (1) can be pushed into the base part (1) from the second end as far as an end position and can be pushed out of the base part (1) from the end position in the opposite direction. When in the end position, the light-guide part (8) and the base part (1) are connected to one another by means of a snap connection and have interengaging surface parts which do not allow relative movement between the base part and light-guide part in any other than the push-out direction. Furthermore, when in the end position, at least one snap connection force has to be overcome in order to allow relative movement between the base part (1) and light-guide part (8) in the push-out direction.
