Abstract: A surgical tool for use in abdominal hysterectomies includes an inner uterine-ring assembly having a ring for insertion into the vagina at the juncture of the cervix and vagina. An outer clamping assembly insertable through a surgically opened abdominal cavity is clamped about the inner ring with the vaginal tissue interposed therebetween. The combination presents a scalpel guide for surgical circumcision of the interposed tissue as well as controls undesirable bleeding from the circumcised tissue.

Abstract: A portable, easy to use cardio pulmonary resuscitation (CPR) pressure indicator is described which can be placed on a patient's chest to transmit successive resuscitation compression forces applied by a treating person and give a perceptible (e.g., audible) signal when an appropriate force and resultant compression stroke has been achieved. In preferred forms, the indicator device includes force transmitting structure presenting a first surface for placement on a patient's chest region, a second surface for engagement by the hands of a person treating the patient, and structure for transmitting force supplied by the person through the first surface and to the chest region of the patient. The overall device further includes a signal generator operably coupled with the force-transmitting structure for giving a perceptible signal when a predetermined force has been transmitted to the patient's chest region.
