Abstract
A cervical clamp for preventing reflux of a fluid medium such as carbon dioxide or a saline solution injected into a uterus. The clamp has a plurality of outwardly bowed, flexible fingers for gripping a cervix. The fingers operate between an open finger position for receiving the cervix and a closed finger position for grasping the cervix and radially compressing it against a sheath in the cervical canal through which the fluid medium is injected into the uterus.
Claims8
A cervical clamp for preventing reflux of a fluid medium injected into a uterus, said clamp comprising
- an elongated externally threaded member with a proximal and a distal end;
- a plurality of outwardly bowed, flexible fingers, each finger having a generally inwardly bent, pointed distal end and being radially connected at a proximal end to the distal end of the elongated threaded member, said fingers adapted to extend from a cervix through a vagina;
- a nut threaded on the externally threaded member;
- and,
- a hollow tubular member connected to the nut for sliding over the fingers between an open finger position for receiving a cervix and a closed finger position for grasping a cervix and radially compressing a cervix against a sheath in a cervical canal through which a fluid medium is injected into a uterus, said clamp preventing reflux of the fluid medium between the sheath and the cervical canal.
A cervical clamp for preventing reflux of a fluid medium injected into a uterus, said clamp comprising
- an elongated externally threaded member with a proximal and a distal end and an open, longitudinal passageway running between said proximal and distal ends, said passageway for accommodating a sheath for insertion into a cervical canal, said sheath movable in the passageway;
- a plurality of outwardly bowed, flexible fingers, each finger having a generally inwardly bent, pointed distal end with a knob and an integral tooth and being radially connected at a proximal end to the distal end of the elongated threaded member, said fingers adapted to extend from a cervix through a vagina;
- a nut threaded on the externally threaded member;
- and,
- a hollow tubular member connected to the nut by two or more struts for sliding over the fingers between an open finger position for receiving a cervix and a closed finger position for grasping a cervix and radially compressing a cervix against a sheath in a cervical canal through which a fluid medium is injected into a uterus, said clamp preventing reflux of the fluid medium between the sheath and the cervical canal.
