    Abstract: The endocervical instrument of this invention comprises, generally, a handle and an elongated basket-like member removably mounted onto the handle. The basket-like member is elongated and generally of rectangular-shape as viewed in plan. The basket member has a wall surface defining an elongated cavity therewithin and an entrance into the cavity from one side of the basket member. One end of the basket member carries a blade means which preferably projects laterally with respect to the entrance to the elongated cavity of the basket member. The blade member projects laterally from the sidewalls defining the entrance to the cavity a sufficient distance to enable an endocervical tissue strip of approximately 1.5-2 mm., in depth, to be obtained as the blade member is drawn distally towards the external os of the endocervical canal.

  • Patent number: 4031589
    Abstract: A device for intercepting droplets produced by ceiling-engaging sponges, rollers and the like is described. This portable drop cloth has a light weight framework which supports either a flat plastic sheet or a plastic bag, whichever is preferred for specific applications. The framework is attached to a collar-like member so that the unit may be positioned at a desired location along a handle of the ceiling-engaging element. In some embodiments the size of the frame, and its angular position with respect to the handle to which it is attached, may be adjusted.
