Abstract
Surgical separator structure comprising an elongated shaft having a handle at one end and a stem with controlled flexilibity at the other end and a tissue separating tip secured to the other end of the flexible stem. The shaft may have a separate handle part and stem part secured together centrally of the shaft. The tip is preferably spherical and may be constructed to snap on the end of the stem and may also be retained by adhesive or the like. Alternatively, the other end of the stem may be molded into the tip to secure the tip to the stem. In the method of manufacture of the surgical separator, the handle and stem may be separately produced and secured together by a threaded connection while the tip may be snapped over the end of the stem and/or secured thereto with adhesive. Alternatively, the stem may be molded of "ABS" within a recess in the "TEFLON" tip to lock the tip on the stem. The handle is preferably color coded to provide a visual indication of the flexibility of the shaft. The tip is preferably colored a color contrasting to the color of the stem and tissue such as bright yellow and is preferably luminescent.
