Materials List (Return to Contents)
Supplies to build one laparoscopic trainer, stretch and dissect block and puffball holder (students take turns using these items):
Instruments for the class to share:
Each group needs:
Note: Expendable costs are estimated at $6 per group. All other "start-up" non-expendable material costs are for reusable items shared by the class, such as the laparoscopic tools, microscope camera, and supplies to build the surgical trainer, and comes to ~$266.
Tips for obtaining laparoscopic tools: Do a browser search with the terms: buy used laparoscopic tools. Or from the ebay "endoscopy & laparoscopy" category at http://www.ebay.com/sch/Endoscopy-Laparoscopy-/99998/i.html, separately search for "grasper" and "scissors" to find the tools for ~$50 each. From the main ebay website, the path is: business and industrial > healthcare, lab, and life science > medical equipment > endoscopy & laparoscopy. If you run into a medical equipment disclaimer, just go ahead and make the purchase. Example cutter on ebay. Example grasper at ebay.
Introduction/Motivation (Return to Contents)
Laparoscopic surgery (see Figure 1) is a surgical technique in which operations in the abdomen are performed through small incisions made in the abdominal or pelvic cavities. A trocar creates these incisions in the abdomen and provides a sealed conduit, using the cannula, for various instruments used to perform the surgery (see Figure 2). Typically, three incisions are made during each surgery: one for a laparoscope and two dedicated ports for the surgical instruments. The laparoscope consists of a telescopic lens system that is connected to an ex vivo video camera. Light is usually provided by a powerful bulb and is piped into the abdominal cavity via a fiber optic or gel cable. The abdomen is insufflated with carbon dioxide gas to create a region large enough to work in and view.
In this activity, you will perform laparoscopic surgical tasks that are used to assess the validity and maneuverability of new innovative surgical tools using laparoscopic tools and a handmade surgical trainer. In the operating room, physicians perform surgery as carefully and quickly as possible to reduce trauma to the patient. In this activity, your surgery time and mistakes will be recorded to quantify your performance.

Research: Assign students to research laparoscopic surgery on the Internet or at the library and answer the following questions:
Activity Embedded Assessment
Participation: Give students participation points for attempting the tasks.
Reflection Writing & Brainstorming: Ask students to write paragraphs discussing the limitations and difficulties of laparoscopic surgery based on their experiences from this activity. Then have students brainstorm and discuss ideas for improvements that would increase the ease, efficiency and accuracy of laparoscopic surgery.

Additional Multimedia Support (Return to Contents)
Show students a 3:19-minute animation of laparoscopic surgery on YouTube. This 3D medical animation depicts the surgical removal of an appendix using laparoscopic instruments. The animation begins by showing an inflamed appendix (appendicitis), followed by the placement of the laparoscope. Afterward, one can see the surgical device staple, cut and remove the inflamed appendix. Then the abdomen is flushed with a sterile saline solution.
