Intuitive Surgical Inc. is an American corporation that manufactures robotic surgical systems, most notably the da Vinci Surgical System. The da Vinci Surgical System allows surgery to be performed remotely using robotic manipulators. The company is part of the NASDAQ-100 and S&P 500. Intuitive Surgical has installed over 1,242 systems worldwide as of July, 2009.[4] Computer Motion was a competitor that merged with Intuitive Surgical in 2003.

History[edit]

The research that eventually led to the development of the da Vinci Surgical System was performed in the late 1980s at non-profit research institute SRI International.[5] In 1990, SRI received funding from the National Institutes of Health. SRI developed a prototype robotic surgical system that caught the interest of the Defense Advanced Research Projects Agency (DARPA), which was interested in the system for its potential to allow surgeons to operate remotely on soldiers wounded on the battlefield.

In 1994, Dr. Frederic Moll became interested in the SRI System, as the device was known at the time. At the time, Moll was employed by Guidant. He tried to interest Guidant in backing it, to no avail. In 1995, Moll was introduced to John Freund, who had recently left Acuson Corporation. Freund negotiated an option to acquire SRI's intellectual property and incorporated a new company that he named Intuitive Surgical Devices, Inc. At that point Freund, Moll, and Robert Younge (also from Acuson) wrote the business plan for the company and raised its initial venture capital. Early investors included the Mayfield Fund, Sierra Ventures, and Morgan Stanley.[citation needed]

The company refined the SRI System into a prototype known originally as "Lenny" (after the young Leonardo da Vinci), which was ready for testing in 1997. As the company's prototypes became more advanced, they were named using da Vinci themes. One was named "Leonardo", and another was "Mona". The final version of the prototype was nicknamed the da Vinci Surgical System, and the name stuck when the system was eventually commercialized. After further testing, Intuitive Surgical began marketing this system in Europe in 1999, while awaiting FDA approval in the United States.[citation needed]

The company raised $46 million in an initial public offering in 2000. That same year, the FDA approved use of the da Vinci Surgical System for general laparoscopic surgery, which can be used to address gallbladder disease and gastroesophageal disease. In 2001, the FDA approved use of the system for prostate surgery. The FDA has subsequently approved the system for thoracoscopic surgery, cardiac procedures performed with adjunctive incisions, and gynecologic procedures.[6]

Shortly before going public, Intuitive Surgical was sued for patent infringement by Computer Motion, Inc, its chief rival. Computer Motion had actually gotten into the robotic surgery field earlier than Intuitive Surgical, with its own system, the ZEUS Robotic Surgical System. Although the ZEUS system was approved in Europe, the U.S. Food and Drug Administration had not yet approved it for any procedure at the time that the FDA first approved the da Vinci system. The uncertainty created by the litigation between the companies was a drag on each company's growth. In 2003, Intuitive Surgical and Computer Motion agreed to merge, thus ending the litigation between them.[7] The ZEUS system was ultimately phased out in favor of the da Vinci system.

The da Vinci Surgical System is a robotic surgical system. The system is controlled by a surgeon from a console. It is commonly used for prostatectomies and increasingly for cardiac valve repair and gynecologic surgical procedures.[8][9]

Overview[edit]

The da Vinci System has been designed to improve upon conventional laparoscopy, in which the surgeon operates while standing, using hand-held, long-shafted instruments, which have no wrists. The da Vinci System consists of a surgeon’s console that is typically in the same room as the patient and a patient-side cart with four interactive robotic arms controlled from the console. Three of the arms are for tools that hold objects, act as a scalpel, scissors, bovie, or unipolar or bipolar electrocautery instruments. The fourth arm is for an endoscopic camera with two lenses that gives the surgeon full stereoscopic vision from the console. The surgeon sits at the console and looks through two eye holes at a 3-D image of the procedure, meanwhile maneuvering the arms with two hand controllers. Right sided foot controls operate the energy supplied to the instruments to cauterize, coagulate, or cut the tissue. Left sided foot controls help to move the endoscopic camera in or out and therefore bring the surgical image closer or further away. The da Vinci System scales, filters and translates the surgeon's hand movements into more precise micro-movements of the instruments, which operate through small incisions in the body.

By providing surgeons with superior visualization, enhanced dexterity, greater precision and ergonomic comfort, the da Vinci Surgical System makes it possible for more surgeons to perform minimally invasive procedures involving complex dissection or reconstruction. For the patient, a da Vinci procedure can offer all the potential benefits of a minimally invasive procedure, including less pain, less blood loss and less need for blood transfusions. Moreover, the da Vinci System can enable a shorter hospital stay, a quicker recovery and faster return to normal daily activities.[10]

A da Vinci Surgical System costs approximately $1.5 million.[11] The new da Vinci SI released in April 2009 cost about $1.75 million. In addition, there are maintenance contracts plus expenditures for instruments used during surgery. Surgical procedures performed with the robot take longer than traditional ones. Critics have pointed out that hospitals have a hard time recovering the cost and that most clinical data does not support the claim of improved patient outcomes.[9]

Criticism[edit]

On May 19, 2000, Computer Motion, Inc. of Goleta, California filed suit against Intuitive Surgical alleging infringement by Intuitive Surgical of seven U.S. patents relating to robotic surgery.[12]

While the use of robotic surgery has become an item in the advertisement of medical services, critics point out a lack of studies that indicate long-term results are superior to results following laparoscopic surgery.[13] On the other hand, there is no question[citation needed] that some procedures that have traditionally been performed with large incisions can be converted to "minimally invasive" endoscopic procedures with the use of the Da Vinci, shortening length-of-stay in the hospital and reducing recovery times. But because of the hefty cost of the robotic system, it is not clear that it is cost-effective for hospitals and physicians despite any benefits to patients since there is no additional reimbursement paid by the government or insurance companies when the system is used. Data are absent to show that these increased costs can be justified. Another problem is that in the medical literature very experienced surgeons tend to publish their results. These, however, may not be representative of surgeons with lesser experience.[13] And there is a steep learning curve for surgeons who adopt use of the system.[citation needed]

On the other hand, as more surgeons are being trained on DaVinci systems from the outset of their careers, it is becoming apparent that the skills needed to become a successful DaVinci surgeon are similar to those that any good surgeon must develop. Good hand-eye coordination, a talent for tissue handling, and a thorough knowledge of anatomy are only enhanced through the DaVinci interface. The difficult learning curve of "handling" the robot is merely familiarity with how to bring the machine close to the operating table and attaching it to the patient and how best to position the operating ports to allow optimal access to the target anatomy. These obstacles are overcome quickly and enthusiastically when the surgeon realizes that the actual performance of the operation in the sitting position at the console is less physically demanding and more precise than with traditional laparoscopy. This translates into a more relaxed and 'in-control" surgeon who may suffer fewer of the long-term physical consequences that result from prolonged standing, precarious balancing, and neck craning that often accompany traditional laparoscopic surgery.[citation needed] And finally, DaVinci robotic surgical techniques are learned more quickly by more surgeons than are learned by surgeons who devote themselves to non-robotic laparoscopy only.[citation needed] It is clear[citation needed] that non-robotic laparoscopic techniques are harder to learn and master than robotic techniques.

Hospitals with successful DaVinci programs are finding that their costs are marginally but not significantly[clarification needed] higher with robotic surgery. Greater numbers of patients, especially those that suffer from obesity, can undergo a safe robotic operation, whereas before, non-surgical options were emphasized for those with high BMI values. One advantage to DaVinci may well be its ability to extend safe surgical options to more individuals.

According to published data(citation required) as well as Intuitive Surgical's own data there is 30 percent "abort" rate for robotic surgery. An "abort" is a situation in which the surgeon aborts the use of the robot and assumes conventional laparoscopic surgery. This diminishes the usefulness of the instrument.
