This paper examines the evolution of robotic surgery from its conceptual origins in 1921 through modern applications in complex procedures like cardiac and urological surgery. It analyzes both the substantial benefits—including enhanced precision, faster recovery times, and reduced patient pain—and significant limitations, such as high costs, limited surgeon training availability, and restricted applicability across surgical specialties. The paper also addresses public perception, noting that while patients increasingly accept robotic procedures, many remain unaware of potential risks and complications that media coverage often overlooks.
Far-reaching developments in technology have led to robotic structures being introduced into medical surgery procedures. Scientists have made dynamic attempts to maximize the utilization of robotic structures in order to enhance the efficiency of surgical methods. The idea of using robotic structures to perform humanoid activities was generated by Czech in 1921, which fascinated innovators and caused them to introduce this idea into the field of medicine (Lanfranco et al., 2004). This concept has been pursued in practical studies and has become a center of investigation with technological advancements in order to aid medical surgical methods.
Dr. McEwen, a pioneer of robots in medical science, presented the first robot in 1983 to perform certain tasks in surgery. The robotic structure was used to provide facilitation in orthopaedic surgery procedures. The process involved robots providing assistance in surgical procedures by passing surgical instruments, and these robots were controlled and commanded by surgeons using voice recognition mechanisms. Moreover, these robots were utilized in approximately 60 surgeries, and their most significant contribution consisted of assistance in the most challenging surgical procedure of that time: brain biopsy (Hockstein et al., 2007). The success of robots in this procedure ensured that they could be used in more technical, time-intensive, and diverse surgeries.
The application of robots was further advanced in 1985, involving robotic assistance in performing prostatic surgery. This procedure took place at St. Thomas Hospital in London and was directed by Dr. Nathan. Further advancements in robotic structures enhanced the application of a robot named Robodoc, which was used in hip replacement procedures with the cooperation of IBM (Lanfranco et al., 2004). Moreover, heart bypass surgical methods were also enhanced with the use of robots in 1998 in Germany. The outcomes of these surgical procedures demonstrated that the efficiency and effectiveness of surgery increased with the application of robots known as da Vinci in surgical processes, proving them to be more beneficial in critical surgeries. In 2006, the robot was assigned to technically perform surgery on a human male for the heart, and the study demonstrated its high efficiency in surgical success compared to human surgeons. By 2009, robots had been upgraded to respond to force-feedback during operations, and critical surgeries such as kidney transplant and bladder reconstruction became possible with increased efficiency (Yates et al., 2011).
A combined effort by NASA and DARPA resulted in the development of a robotic system capable of conducting telesurgery in which the physical presence of the surgeon was not required. The robot was directed remotely by the surgeon to perform the surgery. The utilization of telesurgery proved its efficiency in laparoscopic surgeries with an increased rate of dexterity compared to human-operated surgeries (Hockstein et al., 2007).
Although robotic surgery is proven to be beneficial and dexterous in medical science, the technology is not yet proven to be fully dependable; therefore, this advancement in robotic technology is still in its developing stage. Further studies and improvements are required to enhance its effectiveness. The concept generated by Czech in 1921 has taken form in reality, and over time its utilization has been enhanced, but further advancements are also crucial and necessary to aid medical surgeries.
The application of robotic systems to conduct laparoscopic operations, in which surgeons are required to make small incisions in the human body, can be complicated. However, the utilization of robots increases visual aid to surgeons by providing three-dimensional sight, which enables the surgeon to operate surgical methods in a much more effective way. The images generated by the robotic structure provide surgeons with an enhanced view of human tissue insights so that surgeons can manipulate the operating process accordingly (Lanfranco et al., 2004).
Furthermore, robots increase the stability of the operating process compared to human hands. This stability of incision enables surgeons to contact specific areas and tissues in a perfect manner. In contrast, if operated manually by surgeons, the instability of human hands or tremors could lead to adverse surgical outcomes. Therefore, the enhanced view and surgeon's capability to reach complex tissues decrease the number of incisions made in each surgery because miniature surgical robots inside the human body provide surgeons with the ability to maneuver within tissues and operate accordingly, which ultimately increases the success of surgical outcomes (Corcione et al., 2005).
An experimental study conducted by White (2013) compared robots and surgeons performing surgical tasks. The results proved that surgeries performed by robots were more precisely done and took less time compared to traditional surgeries conducted by surgeons. Moreover, the study also showed that patients who were operated on by robots reported faster recovery rates, with empirical studies demonstrating that recovery was 20 percent faster than recovery in patients operated on traditionally by surgeons.
Surgery assisted by robotic systems tends to have fewer complications than surgeries operated conventionally. The sterilization and antibacterial structure of robots have proven to be less infectious for patients, allowing them to recover at a faster pace and achieve their health objectives more quickly. Patients who have undergone robotic surgery are exposed to less pain during procedures due to microscopic incisions and precise manipulation. These aspects of robotic surgery systems have ultimately resulted in decreased hospitalization days for patients and faster overall recovery (Abbou et al., 2001).
Technological advancements have been made to facilitate healthcare services. Although these inventions and advancements can make complex surgeries possible and can visualize tissues and cysts that are not visible to the human eye, continuous advancements in this field have contributed to better healthcare services. Surgeries that are partly operated by robots and medical staff traditionally have proven to reduce the overall time required for the surgical process and are found to be less painful for patients.
There are only a few surgeries that can be operated with robotic assistance, whereas a vast area of surgical methods still needs to be adapted to robotic systems. The continuous upgrade and maximum utilization of robotic systems will increase additional costs in surgical procedures, making the overall cost of the surgical procedure higher and less affordable for patients. It has been believed by experts that technological enhancements in terms of software upgrades and faster processor installations in these robots will make the surgical process efficient but increasingly costly (Lanfranco et al., 2004).
The application of robots benefits mankind in terms of healthcare facilities, but these robots are exceptionally large in size, and their installation requires larger operating rooms compared to current facilities. Furthermore, the movement and passage of robotic arms during the surgical process can be disruptive for operating staff that is usually required around patients during surgery. Therefore, the utilization of robots in hospitals will require larger rooms for their facilitation, which will increase the overall cost of the project. The idea of miniaturizing robots is appealing, but the process of remodeling will take time, and the costs of advanced research will increase. Although robotic technology was introduced in medical science with the basic objective of cost reduction for patients and improved efficiency, continuous research and development in robotic systems will cause continuous increases in their application costs for surgical procedures.
Robotic surgery can assist certain surgical processes, but human assistance and surgeons are required to operate these robots. Surgeons and medical staff are profoundly trained in traditional surgeries but require proper training to operate robotic systems. The availability of trained surgeons to operate robots is not uniformly distributed throughout the world, and patients may or may not be able to travel to reach appropriate medical facilities. Some research has also proven that there is no significant difference between outcomes achieved by robotic surgeries and those achieved by traditional surgeries.
The application of robots in surgeries also prevents the surgeon from touching the tissue being operated on. During robotic surgeries, robotic arms make incisions while concealing tissue exposure from the surgeon, making the surgeon unable to judge the surrounding tissue and unable to make necessary decisions to avoid harmful consequences. Furthermore, surgeons being unable to touch and use incision instruments directly can cause hazardous situations because the surgeons will not be able to analyze whether the robotic systems are malfunctioning during the procedure.
