68. Endoscopic ManipulatorAn endoscope is typically a 70-180 cm long flexible tube of 11mm diameter. Currently, endoscopic tools are positioned by sliding in and out, and by controlling the bending of the last 10 centimeters of the endoscope. This radius is too large for some tasks, and bending tends to displace surrounding tissue making positioning more difficult. The endo-platform, designed by Jeff Wendlandt, will allow finer positioning control for endoscopic tools. Closed-loop control of this device has been implemented; a movie of the endo-platform tracking a circle is available.
69. Robotic hand with wrist and gripper
70. Human InterfacesPrototype glove-like device that senses the positions of the surgeon's fingers and wrist with its flex and rotation sensors. The glove provides a more natural means of control than current minimally invasive tools. It could be used as a master to drive the miniature slave robotic hand described above, if force feedback is not needed.
71. Tactile sensation is extremely important ... To provide local shape information, an array of force generators can create a pressure distribution on a finger tip, synthesizing an approximation to a true contact.
72. Tactile Sensing and Stimulation¨Tactile sensation is extremely important in open surgery to allow the surgeon to feel structures embedded in tissue. Important vessels and ducts are usually shrouded in connective tissue; their presence must be felt rather than seen to avoid damage. Tumors within the liver or colon must be removed without exposure that would allow the spread of cancerous cells. Teletaction allows sensing and display of tactile information to the surgeon. In teletaction, a tactile sensor array can be used to sense contact properties remotely. To provide local shape information, an array of force generators can create a pressure distribution on a finger tip, synthesizing an approximation to a true contact.
73. Human Tactile PerceptionThe limitations of human tactile perception need to be understood when designing a teletaction system. We model an ideal teletaction system simply using two elastic layers placed between the finger and an object. The tactile sensor layer transmits contact stress to a display layer. This system has no spatial sampling limits or level quantization, and allows us to study ideal information transmission, considering the effects of spatial anti-aliasing and reconstruction filters in the sensor and display respectively.

99. STEPS (Sensors) In addition to the direct types of physiologic sensors mentioned, there are what can be considered indirect forms of monitoring, examples being radiology and laboratory chemistry techniques. There has been a tremendous sophistication of these ancillary assessment tools within the fields of diagnostic imaging and body fluid chemistry analysis during this recent time period but even the removal of a simple blood sample, however, should still be considered an invasive procedure.
100. STEPS (Transmittors) Transfer of the information gained from current physiologic monitors (sensors) requires an electrical interface for virtually all types of monitoring devices at this time. This process requires the monitored subject to be physically connected to the devices in some fashion, even if it consists of skin contact electrodes. Remote telemetry monitoring of cardiac function is a currently accepted modality but it has limitations in scope of functions and monitoring distance from the subject. Other forms of remote data transmission have not been developed extensively at this time. The indirect ancillary studies performed are usually processed and analyzed remote from the subject but the results can be digitized and transferred easily with the efficient speed of contemporary computers. The recent trends in the preparation of surgeons for an operative procedure with diagnostic and therapeutic radiology imaging enhancement of anatomic structures can be considered a form of data transfer and interpretation because of the computerized data manipulation that occurs after the subject has undergone the imaging procedure. Telemedicine technology and utilization is undergoing a renaissance with the current improvements in computer capability, digital data transmission and societal pressure for equitable distribution of health care services. There is not, unfortunately, a general acceptance of this communication modality in the medical community and it is still far from achieving a broad utility rate at this time, despite a demonstrated high level of comfort with the process from those institutions where telemedicine is utilized frequently. Regardless of which sensor the data is transmitted from, interpretation of the data is still performed by direct human review in virtually all situations, with the exception of a few demonstration projects utilizing neural network decision analysis or computer software-driven management of support devices (e.g. ventilators).
101. STEPS (Effectors) Significant progress from the DOD, DARPA and the recent revolution with minimally invasive surgery (e.g. laparoscopy) has precipitated further research efforts from a variety of institutions to develop remote non-contact forms of interventions, including the utilization of robotics and teleprescence surgery. There have also been some recent developments of automated effector devices that require only intermittent human direction. These are relatively simple devices but their utility is effective despite the invasive nature of the components. Examples of NASA's earlier contributions are the automated drug delivery systems for people requiring chronic delivery of medications (e.g. insulin) and the automated implantable cardiac defibrillation (AICD) devices for people with chronic, recurring cardiac rhythm disturbances.

123. da Vinci and Zeus compared The operative times and learning curve were significantly shorten with the da Vinci system.
Additionally, the movements appeared to be inherently more intuitive.
Movement with the Zeus system was more like conventional laparoscopic techniques than with the traditional open approach.
However, individual preference, surgical application, and availability of the device still play a large role in system selection at various institutions.

Zeus system to remove a gallbladder from a patient with symptomatic cholelithiasis in Strasburg, France
Operation proceeded without difficulty, and the patient was discharged within 48 h after the operation
One of the main difficulties of operating in this manner is the latency experienced in movement and video images over such long distances
Overcome by using asynchronous transfer mode telecommunication (ATM)
The latency over the 14,000-km distance was 155 ms (safe 300 ms)
The cost of an ATM line $100,000 to $200,000 U.S. dollars per year

Doctors Perform Successful Transatlantic Telesurgery By Steve Gold, NewsbytesSTRASBOURG, FRANCE,19 Sep 2001, 9:59 AM CST A major test of remote surgical robotics took place earlier this month, allowing a group of surgeons in New York to operate on a patient located in France. Researchers with the Institute for Research into Cancer of the Digestive System (IRCAD) say that the operation was carried out on patient in Strasbourg, France, using minimally invasive, or "keyhole" surgery. "The operation, which took place on Sept. 7, was a great success. There were no problems, and the patient has now made a full recovery," Caroline Reiller, a spokesperson for IRCAD, told Newsbytes this morning,
130. Robots in medicine
131. Telesurgery With advances in information technology
advances in communication speed
more cost-effective transmission of data signals
telesurgical applications may one day allow affordable remote surgical intervention
Applications such as terrestrial to space intervention have been considered, and NASA is even considering the application of this technology for a proposed mission to Mars in 2016
In the near future
operate on battlefield patients or patients for whom intimate contact poses a risk to either surgeon or patient
someday access to highly trained robotic specialists in remote areas of the world
train surgeons who may not have access to highly specialized training
Both international and local boundaries are broken, and the question of how to regulate surgeons will become more critical
132. Robotic and telesurgery Robotic surgery has arrived and is growing exponentially.
Surgeons throughout many different subspecialties and from many nations are working to define which surgical pathology will benefit most from this new technology.
Robotic systems have been proved safe and effective by many academic centers, and the technology begins its journey into the hands of the eagerly awaiting public.
133. Business As of June 2003, Intuitive Surgical and Computer Motion have merged and will be basing further development on the da Vinci platform.
