Cervical tenaculum

摘要

A method and device for sealing a patient's cervix around a medical device is described. The device comprises a tenaculum including a base with a device receiving opening extending therethrough and a plurality of arms extending between proximal ends connected to the base and distal ends adapted to apply radial pressure to the cervix in combination with an arm closing element slidable along the arms between open and closed positions. An alternative cervical sealing device comprises an elongated frame with a distal end for placement adjacent to a cervix. The elongated frame defines a device receiving passage and a constriction element coupled to a distal end thereof. The constriction element is operable between a constricted and open configurations for selectively applying a radially inwardly directed force to the cervix. A manual control actuates the constriction element between the constricted and open configurations.
