Semi-rigid biopsy forceps are specialized medical instruments used in hysteroscopy procedures to obtain tissue samples (biopsies) from the inside of the uterus. These forceps are designed to navigate through the working channels of a hysteroscope, allowing healthcare providers to perform diagnostic procedures or collect tissue samples for further examination. The "semi-rigid" designation indicates that these forceps have a degree of flexibility while still maintaining some rigidity for effective maneuverability within the uterine cavity.
