An adjustable weighted speculum for use during vaginal surgery to separate the vaginal walls. The speculum includes a telescopic blade including a primary blade having first and second ends and a recess extending therethrough, and a secondary blade having a first and second end telescopically positioned within the recess of the primary blade. A handle extends from the second end of the primary blade. A locking mechanism is contained within the handle and connected to the secondary blade for selectively moving the secondary blade or locking the secondary blade in position. A weighted element is releasably attached to the second end of the handle. A plurality of channels extend along a side of the secondary blade from the first end to a point along a length of the secondary blade and a single channel extending along the side of said secondary blade from the second end to the point along the length of the secondary blade wherein the single channel mates with the plurality of channels at the point. A tube may be connected to the single channel for connecting a suction device thereto. A hoop mounted at the second end of the handle allows for selective suspension of the weighted element therefrom, the weighted element may vary in size and weight.
