摘要:
A vaginal speculum includes a frame and a first handle assembly pivotally mounted to the frame. The frame defines an opening between a first blade that is attachable to the frame and a second blade that is attachable to the frame opposite of the first blade, and a hinge assembly configured to flex the frame to selectively change a size of the opening. The first handle assembly includes a lever portion and a blade portion coupled to the lever portion. The blades have a proximal end attachable to the blade portion and a distal end portion spaced from the proximal end. When in a first collapsed insertion state, the hinge assembly collapses the frame and the first blade contacts the second blade. When in a second deployed state the hinge assembly expands the frame and the first blade is spaced apart from the second blade.
