Claims24
A speculum adapted for examining a body cavity, comprising:
- a handle having a rearward portion and a forward portion;
- a biasing means interconnected to said handle which maintains said rearward portion and said forward portion of said handle in a spaced apart relationship;
- a stationary ring interconnected to an upper portion of said rearward portion of said handle;
- a traveling ring interconnected to an upper portion of said forward portion of said handle and positioned behind said stationary ring;
- a plurality of blades having a front end and a rear end and a pivot point positioned therebetween which is pivotably engaged to said stationary ring, said rear end of said plurality of blades positioned at least partially within an interior diameter of said traveling ring, wherein when said handle is squeezed, said traveling ring travels away from said stationary ring, and said plurality of said blades pivot around said stationary ring, wherein said front ends of said plurality of blades are separated.

A handheld apparatus adapted for examining a body cavity, comprising:
- a handle having a rearward portion pivotally interconnected to a forward portion;
- a biasing means operably interconnected to said forward portion and said rearward portion of said handle to maintain said handle in a spaced apart relationship until said handle is squeezed;
- a stationary ring interconnected to said rearward portion of said handle and extending upwardly therefrom;
- a traveling ring interconnected to said forward portion of said handle and positioned behind said stationary ring;
- a plurality of blades each having a first end, a second hooked end and a sleeve positioned therebetween for pivotally engaging said sleeve to said stationary ring, wherein when said handle is squeezed, said traveling ring travels arcuately away from said stationary ring and engages said second hooked ends of said plurality of blades, wherein said first ends of said plurality of blades open with respect to one another.

A speculum adapted for examining a body cavity, comprising:
- a forward handle portion having an upper end and a lower end;
- a rearward handle portion having an upper end and a lower end;
- a biasing spring interconnecting said forward handle and said rearward handle, wherein said forward handle and rearward handle are biased in a spaced-apart relationship;
- a stationary ring interconnected to said upper portion of said rearward handle;
- a traveling ring interconnected to said upper portion of said forward handle;
- a sliding blade slidingly interconnected to said rearward handle, wherein said sliding blade can be adjusted in a vertical direction;
- and
- a plurality of pivoting blades having a first end, a second hook end, and a sleeve positioned therebetween, said sleeve rotatably interconnected to said stationary ring and said second hook ends in operable engagement with said traveling ring, wherein when said forward handle and said rearward handle are squeezed together, said traveling ring travels away form said stationary ring in an arcuate path, engaging said second hooks ends of said plurality of pivoting blades and separating said first ends of said plurality of pivoting blades.
