The jaws of a rigid endoscope clasping a kidney stone after its removal. The rigid endoscope is a steel tube containing fibre optics elements that allows the surgeon an illuminated view of the kidney stone & which conducts the mechanism that operates the jaws, which are operately remotely by a pair of scissor handles. The tube is introduced through a small incision in the abdomen; the surgeon manipulates the endoscope onto site whilst looking through the eyepiece. A lens and light source are located at the internal end of the endoscope.
