UT Southwestern doctors test robotic surgeon for laparoscopy

15.02.2006


Surgeons in the Southwestern Center for Minimally Invasive Surgery are studying the use of the latest technology — a $1.4 million robot named da Vinci that, with a human at the controls, filters out tremor, enhances precision, offers three-dimensional imaging and eliminates the inverted manipulation of instruments usually required in laparoscopic procedures.


Having a surgeon with four arms is one of the advantages of the latest robotic technology now being studied at UT Southwestern Medical Center.

The $1.4 million robot named da Vinci can hold a camera in one hand while manipulating tiny laparoscopic surgical tools in its other hands. And it never tires like its human counterparts.

With a human surgeon at the controls, da Vinci filters out tremor, enhances precision, offers three-dimensional imaging and eliminates the inverted manipulation of instruments usually required in laparoscopic procedures.



"The buzzword is ’more precise than humanly possible.’ That’s the rationale for this technology," said Dr. Daniel Scott, director of the Southwestern Center for Minimally Invasive Surgery and assistant professor of surgery at UT Southwestern.

Although testing the four-armed robot is still ongoing, Dr. Scott said, "It seems advantageous from the standpoint of precision for some procedures."

Da Vinci is most popular in urology for that reason, especially for prostate operations. It’s also proved useful in surgeries on the esophagus and stomach. Researchers also are investigating its practicality for cardiac surgery such as coronary artery bypass grafting and valve replacement.

"It may well prove useful for general surgery procedures that have traditionally required open incisions like biliary reconstruction or pancreatic surgery," Dr. Scott said.

Laparoscopic surgeries, also called minimally invasive surgeries, are performed via several tiny holes rather than one long incision, reducing post-operative pain and recovery times. The method is increasingly popular.

The first robotic surgery, performed in 1995, relieved the need for an assistant to hold the camera during laparoscopic procedures. Da Vinci represents the next step, offering an instrument that actually performs the surgery based on controls handled by the surgeon.

"It’s not difficult to learn," Dr. Scott said. But he said it does take longer to set up, mostly to position the robot. It (the robot) is also expensive and cumbersome, which limits the operative field and can make it impractical for exploratory surgeries or surgeries that require surgeons to go in more than one area.

"It takes choreography," Dr. Scott explained.

Surgeons are still learning what its full potential is. But to be successful, Dr. Scott added, "It needs to supersede laparoscopy in terms of efficiency before the average surgeon is going to use it. But as this technology continues to evolve, no doubt it will be miniaturized. Smaller is going to be better."
Automation may also be in the future, with a doctor pointing to sections of tissue that need suturing and the robot doing it. That could potentially be integrated with computed tomography or magnetic resonance imaging scans, which could offer opportunities for dress rehearsals of procedures.

Another potential for the technology is for telerobotic surgery across distances — doctors in one city using the robot (to perform an operation) in another city. The first test of such a surgery was a successful trans-Atlantic gallbladder procedure, with the surgeon in New York and the patient in France.

"It certainly could have applications for rural surgery or mentoring surgeons in the community on new procedures," Dr. Scott said.

"There are big permutations for the future of surgery, and that’s why we need to be leaders in this field as a medical school and as a center dedicated to minimally invasive surgery," he said. "We have a strong track record of embracing robotics and research into this new type of technology here, and we look forward to continuing those activities with this new acquisition."

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
