Abstract
An optical switch (10) includes a light input (12a), a plurality of light outputs (12b) and at least one light pathway movable from a first position where a light communication path is formed between a light input (14a) and a first light output (14b) and a second position where a light communication path is formed between the light input and a plurality of light outputs. Multiple light pathways are configured within the switch and selectable by rotation of a switch housing part enabling sequential selection of light communication paths. The switch can be used on a surgical device to control illumination of the surgical field during a procedure.
Claims26
An optical switch comprising:
- a base plate comprising a first plurality of bores for light input and light output;
- and
- a light pathway plate comprising:
- a second plurality of bores defining a plurality of light pathway inputs and a plurality of light pathway outputs;
- a first surface on which first surface a plurality of light pathways are formed between a light pathway input of the plurality of light pathway inputs and at least one light pathway output of the plurality of light pathway outputs, the plurality of light pathways being formed in an optical cable bundle on the light pathway plate;
- a second surface opposite the first surface for cooperation with the base plate;
- and
- wherein said light pathway plate is selectively movable with respect to the base plate from a first position where a first light communication path connects a light input and a first light output and a second position where a second light communication path connects the light input and at least one further light output.
