Force-Feedback and Time Delay

The ability to carry out delicate manipulations relies greatly upon feedback. For example it is easy to learn how much pressure is required to handle an egg. In robotic surgery, surgeons need to be able to perceive the amount of force being applied without directly touching the surgical tools. Systems known as force-feedback, or Haptic technology, have been developed to simulate this. However these systems are very sensitive to time-delays such as those present in the networks used in remote surgery.

Possible Uses

One possible use of remote surgery is the Trauma-Pod project conceived by the US military under the Defense Advanced Research Agency. This system is intended to aid wounded soldiers in the battlefield by making use of the skills of remotely located medical personnel.

Another future possibility could be the use of remote surgery during long space exploration missions.

Limitations

For now, remote surgery is not a widespread technology in part because it does not have sponsorship by the governments. Before its acceptance on a broader scale, many issues will need to be resolved. For example, established clinical protocols, training, and global compatibility of equipment must be developed. Also, there is still the need for an anesthesiologist

and a backup surgeon to be present in case there is a disruption of communications or a malfunction in the robot. Nevertheless, Operation Lindbergh proved that the technology exists today to enable delivery of expert care to remote areas of the globe.
