Abstract: A speculum includes a main body with a pair of first dilator fingers that are connected at their respective proximal ends to the main body. A second dilator finger extends between the first dilator fingers and is attached to the main body. An actuator is pivotally coupled to the main body. The actuator is formed with a third dilator finger that is located between the first dilator fingers and opposite the second dilator finger. When the actuator is pivoted, the third dilator finger immediately commences to pivot away from the remaining fingers. After a predetermined degree of pivot, the actuator comes into contact with the inside of the first fingers to cause the distal ends of those fingers to move away from each other.

Abstract: A speculum 10 includes a main body 12 with two dialator fingers 14A and 14B that are connected at their respective proximal ends 16A and 16B to the main body 12. A further dialator finger 28 extends between the fingers 14A and 14B and is fixed to the main body 12. An actuator 20 is pivotally coupled to the main body 12. The actuator 20 is formed with a dialator finger 70 that is located between the fingers 14A and 14B and opposite the fixed finger 28. When the actuator 20 is pivoted the finger 70 immediately commences to pivot away from the remaining fingers 14 and 28. After a predetermined degree of pivot, the actuator 20 comes into contact with the inside of fingers 14 near their approximal ends 16 to cause the distal ends of those fingers to move away from each other. Fingers 14A and 14B are hinged about respective canted hinge axis so that when they are abutted by the actuator 20 they move in a combined upward and sideways motion.

Abstract: A speculum (10) includes a main body (12) with two dilator fingers (14A and 14B) that are connected at their respective proximal ends (16A and 16B) to the main body (12). A further dilator finger (28) extends between the fingers (14A and 14B) and is fixed to the main body (12). An actuator (20) is pivotally coupled to the main body (12). The actuator (20) is formed with a dilator finger (70) that is located between the fingers (14A and 14B) and opposite the fixed finger (28). When the actuator (20) is pivoted the finger (70) immediately commences to pivot away from the remaining fingers (14) and (28). After a predetermined degree of pivot, the actuator (20) comes into contact with the inside of fingers (14) near their proximal ends (16) to cause the distal ends of those fingers to move away from each other. Fingers (14A and 14B) are hinged about respective canted hinge axis so that when they are abutted by the actuator (20) they move in a combined upward and sideways motion.
