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. The floor of the basket member is preferably pivotally mounted to the basket member end portions or sidewalls, and each strip of endocervical tissue may be readily removed from the floor of the basket member--after the floor thereof is pivotally disengaged from its normally closed position.
