During a laparoscopic cholecystectomy, traditionally, four incisions are made. One is for the laparoscope, two are the operating ports, and one is to hold the gallbladder to expose the Calot’s Triangle that needs to be cauterised to separate the gallbladder from the liver. Endoretractor was designed by Lata Chawla with BETiC and under the guidance of Dr. Rasik Shah to hold the gallbladder in place. This device eliminated one port and the need for human assistance during the surgery.

As the endorectal retractor in itself is an innovative design, no specific devices were used to deploy it. A crude set of devices and a lengthy procedure were used to test and validate the device. As the device is soon to be launched into the market, the need for a sophisticated deployer device arose.
