Sterile field

A sterile field or steri-field was a radiation field, standard on Starfleet operating tables, which kept the surgical site completely . The surgeon's hands and medical instruments were automatically sterilized each time they entered and exited the field. The field was activated manually. The steri-field replaced 20th century "scrubbing in" and sterile preps before surgery. (; )
