The Sklar Black Graves Vaginal Speculum is used for laser gynecological procedures. It is a double blade duckbill speculum inserted with the blades closed. The blades are then opened by an external lever and screw. The Graves Speculum has wider blades than the Pederson Speculum and the practitioner can best determine which type and size speculum is most appropriate for the patient. The Sklar Black Graves Vaginal Speculum is available with a permanent smoke evacuation tube, a loop for disposable smoke evacuation tubing, or no smoke evacuation. Sklar Black Laser instruments feature a non-reflective black polymer coating applied over the sandblasted instrument developed specifically for laser surgeries. This safe, durable coating reduces laser reflection to less than one-tenth of a percent, ensuring a safer surgical environment for patients and surgical staff. All Sklar Black coated instruments comply with biological testing requirements for cytotoxicity, sensitization regulatory, and ISO 10993 requirements. They also comply with the Pre-Vacuum and Gravity Cycle Steam Sterilization Validation of ANSI/AAMI ST79. This product is an extra large speculum with 4-3/4" X 1-1/2" blades. It has a loop to hold and direct disposable smoke evacuation tubing.
