Students preparing to enter medical fields are required to take physics. To increase their interest in physics, a low-cost classroom medical activity is presented introducing them to the basics of endoscopic visualization and navigation. Incorporated in the activity are basic surgical techniques such as resection with single or multiple operators. Students also learn to appreciate the importance of physics since the endoscope works on the principle of total internal reflection. The tasks involve two pick-up tools with retractable claws available at hardware stores and an inexpensive endoscope with Bluetooth that sends video to student smartphones.
