Method to Close Laparoscopic Fascial Trocar Sites

Stanford University, 2007 - $15,820

Laparoscopic surgery, also called minimally invasive surgery, is a surgical technique in which operations in the abdomen are performed through small incisions (usually 0.5-1.5 cm), as compared to the larger incisions common in traditional surgical procedures. The key element in laparoscopic surgery is the use of a telescopic rod/lens system, usually connected to a video camera, called a laparoscope. Using carbon dioxide, the abdomen is blown up like a balloon, elevating the abdominal wall above the internal organs and giving the surgeon room to operate. This approach has a number of advantages, including reduced blood loss, which means less likelihood of needing a blood transfusion; a smaller incision, which means shorter recovery time; and less pain, which equals less pain medication needed.

The approach isn't without drawbacks, however, as one of the most frustrating and time-consuming parts of the surgery is closing the small port sites in the abdominal wall that are made when accessing the operative site. If the port sites are closed improperly, the patient is at increased risk of hernia or bowel problems, requiring further treatment. This E-Team has developed a solution to automatically, safely and reliably close the port sites. The 10mm device has two opposing wings that open when placed into a port. An indicator on the device alerts the surgeon when the wings are in their final position, and the surgeon locks the device into position by pushing a plunger that drives two flexible needles from the shaft into the wings. The surgeon then releases the wings and pulls out the device, leaving a looped suture around the port site opening.
