1. A speculum, comprising:
- a lower blade connected to a handle portion via a curved portion, the handle portion including a proximal end, a distal end and at least one sidewall connecting the proximal end and the distal end;
an upper blade connected to a rotational lever portion extending from a proximal end of said upper blade;
a toothed ratchet member having a plurality of teeth corresponding to a plurality of fixed open states, wherein each tooth of said plurality of teeth defines a corresponding discrete fixed open state when the respective tooth is directly engaged with the rotational lever portion;
a link member connecting the upper blade and the lower blade to allow the upper blade and the lower blade to move between said plurality of fixed open states and a closed state;
a lighting assembly comprising at least one light source and at least one energy storage device, said lighting assembly being built into a cavity formed in the sidewall of the handle portion; and
a light guide that originates in said handle portion and terminates on an interior surface off said lower blade.
