Cincinnati Surgeon Leads First Test of Mobile Robotic Surgery

07.06.2006


A team of military, telecommunications and surgical experts led by University of Cincinnati (UC) faculty are using an unmanned aircraft and sophisticated communication tools to take the next step toward making “telesurgery” a reality.



Telesurgery is a new approach to surgical care in which a surgeon performs operations using a surgical robot and advanced computer technology on a patient located miles away.

Timothy Broderick, MD, assistant professor of surgery at UC and medical director for its Center for Surgical Innovation (CSI), is leading the first test of a prototype communications platform for mobile telesurgery: the High Altitude Platforms for Mobile Robotic Telesurgery (HAPsMRT).


This two-phase telesurgery experiment takes place between Simi Valley, California—a desolate and arid area surrounded by hills and plains—and Seattle, Washington, June 5–9.

The HAPsMRT model—developed in collaboration with the U.S. Army’s Telemedicine and Advanced Technology Research Center and the University of Washington—uses an unmanned airborne vehicle (UAV), or “drone,” as the communications connecting point between a surgeon in one part of the country and a patient located hundreds of miles away.

Current telesurgery tools rely on satellite communication and streaming video delivered via high-speed Internet. In remote locations, explains Dr. Broderick, satellite signals are not always dependable and can result in delays that make surgery difficult.

“Reliable, high-speed communication signals are critical for telesurgery to work in day-to-day patient care,” explains Dr. Broderick. “Our ultimate goal is to eliminate the communications lag to enable the surgeon to safely operate on a remote patient in real time.”

HAPsMRT utilizes low-latency communication transmissions, so the communication signals travel over a shorter distance and with fewer delays.

In phase one of the mission, a simulated patient and robot will be located five miles north of Dr. Broderick at the AeroVironment Flying Field. Dr. Broderick will sit behind the surgical robot control console and operate on the simulated patient using streaming video fed into the console from the UAV.

In phase two of the experiment, Dr. Broderick will travel to the University of Washington and operate on the same simulated patient in Simi Valley from behind a surgical robot control console in Seattle.

Throughout the mission, the research team will evaluate the UAV’s communications capabilities—including speed and quality of video streaming, information time lapses and suturing precision—to see how they are affected by an extreme environment.

“We need to find better ways of delivering emergency and specialized surgical care to patients when they are hundreds of miles away from the nearest hospital,” explains Dr. Broderick. “When it’s perfected, telesurgery could quickly become the medical norm for remote places, including battlefields, extremely rural towns—even space.”

Founded in June 2003, the CSI is an interdisciplinary collaboration between the departments of surgery and biomedical engineering at UC and leading government and industry partners.

One of only a handful of centers of its kind across the nation and the only one in the Midwest, the CSI focuses on addressing unmet medical needs, such as developing minimally invasive robotic surgery and telesurgery techniques that will improve the way physicians deliver and teach medicine.

The 3,700-square-foot facility includes an eight-bench teaching lab with advanced audiovisual and telecommunications capabilities—such as international videoconferencing and direct linkages to the operating rooms at University Hospital, UC’s primary teaching facility. The center also has a sterile operating room outfitted with specialized medical equipment, including the da Vinci surgical robot.

In March 2005, Dr. Broderick and his UC team led the nation’s first live telesurgery, using the da Vinci surgical robot, from Ohio to California.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
