offers ultra-precise suctioning of secretions during surgery-ORTHODPEDICS
Frazier suction tip
33
the most common suction instrument in the world for use in BLADDER Sx. It has a large opening surrounded by a bulbous head, designed to allow effective suction without damaging surrounding tissue. It is used to suction oral secretions in order to prevent aspiration, as well as other bodily fluids
Yankauer suction tip

used for lifting bone or removing periosteum—to remove periosteum and other soft tissues from the surface of bones. They are designed with a blade-like structure at the end of a stout handle. The blade may have sharp or blunt edges and come in various sizes
Periosteal elevator
35
used for debriding cartilage or bone defects—to scrape the surface of relatively dense tissue to remove loose or degenerate tissue (bone marrow, necrotic bone, cartilage flaps, abscess material). It has a small cup-like structure at the end of a handle. The cup has a very sharp cutting edge and comes in various sizes
Bone curette
36
used with a mallet to cut through bone—to cut or shape bone and cartilage, it is tapered on both sides to form the cutting edge and is used with a steel or plastic mallet
