ABSTRACT:
Surgical method and instrument such as a snare or forceps clamps, which can be moved to a position to firmly grasp a polyp. A tissue marking agent is disposed on the surface of the instrument that contacts a polyp, and the marking agent is crushed against the polyp. The marking agent is absorbed by the polyp and stains the tissue from which the polyp projects, the assist in visualizing the polyp site if conventional surgery is later required. The method and device may optionally provide for cutting and removing of the polyp and for application of a hemostatic agent to the polyp base to minimize bleeding.
