An integrated imaging system under development at the University of Wisconsin-Madison could significantly advance laparoscopy. The system is said to take advantage of variable focal length micro-lens systems pioneered by Hongrui Jiang, professor of electrical and computer engineering at UW-Madison.
“This whole project was generated and driven by both sides – from the pursuit to address engineering challenges to the pursuit to solve clinical and medical problems,” Jiang said. “The advantage of our approach is that we gave the clinical requirements and disadvantages a lot of thought so that we could come up with a comprehensive solution to address all of the problems.”
The new system centres around retractable micro-lens arrays integrated onto the end of each port. When a port is inserted into the body, these cameras will flare out in a ring, allowing the surgeon to use the port simultaneously for imaging and operating. Using software or voice commands, the surgeon can tune the focus of each camera to adjust the depth of field, which improves the image quality. Multiple cameras on each port will provide an immersive, three-dimensional view of the procedure, yet their location near the abdominal wall will help to minimise spatter that ordinarily would accumulate on a traditional camera placed right at the site of the procedure.
“In most current laparoscopic procedures, the camera presents several challenges – one of which is that the surgeon can’t operate it independently,” said Charles Heise, a UW-Madison professor of surgery. “Another person must hold the camera, manipulate it, focus it, and move it in and out to clean it,” he says. “It has a limited field of view and it ties up one of the ports.”
While the researchers have made significant strides, they will continue to refine the lens and camera technology. They also will focus on developing algorithms for processing the images from multiple cameras and stitching them seamlessly into a single, 3D view, as well as developing prototypes for laparoscopic simulators that will allow them to gauge how surgeons use the system.
