We developed a surgical tool to help remove gallstones 10 millimeters and larger during laparoscopic surgery. Existing tools struggle to remove the larger stones, often forcing surgeons to convert to open surgery, which leads to longer recovery times and increased complications. We identified the surgeon’s needs and translated them into design specifications. We optimized part selection, refined geometries and incorporated mechanical advantage into the device. This tool enables surgeons to complete gallstone removal through small laparoscopic incisions rather than converting to open surgery.
