  • A radially expanding trocar for laparoscopic cholecystectomy includes an awl, a cannula, a seal, and a valve connected to the seal. A balloon extends within the cannula. A lower portion of the cannula can be made from any suitable, expandable material. An inflation tube can be in fluid communication with the interior of the balloon and the valve to allow air or water into the balloon. Inflating the balloon can cause the balloon to press against an inner surface of the peripheral wall of the cannula, expanding the peripheral wall and increasing a diameter of the cannula. The balloon can be deflated to release the pressure on the peripheral wall and decrease the diameter of the cannula to its original size, e.g., 12 mm.
