Challenges in Robotics
Crowdedness of Arms and Collision Risks:
Robotic surgery grapples with a significant challenge posed by the crowdedness of robotic arms, both internally and externally. This overcrowding elevates the risk of collisions, which can disrupt the seamless execution of surgical procedures. Particularly in robot-assisted minimally invasive surgeries (MIS), collision risks emerge from interactions with surgeon-controlled instruments and nontarget tissues during surgical tasks. Addressing this challenge requires the development of advanced controllers to prevent collisions, safeguard the robotic system, and enhance the safety and efficacy of robot-assisted MIS. These collisions, if unchecked, have the potential to inflict damage on the robotic system or harm normal body tissues, underscoring the need for controllers to prevent collisions, especially when the in vivo scene is not visible to surgeons.
Restriction on Surgeons and Healthcare Systems:
Optimizing the efficiency of surgeons is a pivotal imperative in the realm of robotic surgery. The primary goal is to refine and streamline the movements of surgeons within the robotic system, aiming to enhance precision while mitigating procedural complexities. A notable challenge in this pursuit is the limited haptic feedback experienced by surgeons during robotic procedures². Unlike traditional surgery, where surgeons can directly feel tissues and resistance, robotic systems provide restricted tactile sensations. This reduction in haptic feedback necessitates an adaptation in the surgeon's approach to ensure accurate maneuvering and procedural success. Additionally, there is a significant dependence on technology inherent in robotic surgery. Surgeons need specialized training to operate robotic systems effectively, creating a scenario where only a subset of surgeons can perform procedures using this technology, potentially limiting its widespread adoption. The learning curve associated with mastering robotic surgical systems further highlights the complexity of integrating this technology into medical practice, requiring surgeons to invest time and practice to attain proficiency in operating the robotic console and translating their skills from traditional surgery to the nuances of a robotic platform.
Cost and Availability:
Cost and availability pose additional challenges to the adoption of robotic surgery. The substantial financial investment required for acquiring and maintaining robotic systems³ may create barriers, limiting access to this technology in certain healthcare settings. Not all hospitals or surgical centers may have the financial resources to invest in these advanced robotic platforms.
Limitations of Robotic Surgery
Effective communication and coordination within the surgical team are crucial elements during robotic procedures. The intricate nature of these surgeries emphasizes the need for seamless teamwork to achieve successful outcomes and minimize the risk of errors. Synchronization among team members, along with adequate training in working with the robotic system, becomes paramount.
In addition, procedure-specific constraints may pose challenges. Certain robotic systems have limitations in the types of procedures they can perform. Surgeons may encounter restrictions tied to the specific capabilities of the robotic platform, influencing the range of surgeries that can be conducted robotically. A nuanced understanding of the robotic system's capabilities is essential, guiding surgeons in the selection of procedures that align with optimal outcomes.
Furthermore, traditional robotic surgery introduces port-related challenges. The use of multiple ports, each featuring larger diameters (e.g., 11mm), deviates from the established minimally invasive approach characterized by 5mm ports in laparoscopy.
The performance of intricate and specialized procedures, particularly in oncological surgeries, is a significant challenge, constituting only of cases due to their delicate nature. Addressing these challenges highlights the importance of ongoing advancements in robotic technology, aiming to overcome port limitations and broaden the scope of specialized procedures that can be performed robotically.
In the past two decades, minimally invasive techniques for treating solid organ tumors have evolved, initially through laparoscopic approaches and later through robotic surgery. The introduction of robotic platforms around the turn of the century has played a crucial role in overcoming limitations associated with laparoscopic surgery. These advancements include high-definition three-dimensional visualization, wristed instruments, tremor stabilization, reduced operator fatigue, and improved ergonomics. Despite the acknowledged benefits of minimally invasive surgery, there is limited long-term evidence supporting its superiority over traditional approaches in cancer surgery.
Moreover, a robotic approach is often linked to extended operative times and higher costs compared to laparoscopic methods. Critics argue that the use of robotic surgery should be justified by demonstrating superior functional and oncologic outcomes. While current literature supports the feasibility, safety, and short-term outcomes of robotic surgery in surgical oncology, there is a lack of understanding regarding its impact on long-term oncologic outcomes.
The future landscape of robotic surgery is marked by exciting possibilities driven by advancements in artificial intelligence (AI), expanding applications, and the continuous effort to overcome existing challenges.
Artificial Intelligence Integration:
AI plays a pivotal role in the current trajectory of robotic surgery, providing crucial guidance, information, and enhancing preoperative and intraoperative planning processes. The future envisions autonomous decision-making by surgical robots, heralding a new era of improved patient outcomes and procedural efficiency. Recent successes in AI integration include Intuitive Surgical's digital tool for surgeons to analyze techniques, machine learning automating surgical procedures, and the application of AI to enhance decision-making and augment surgical processes. The integration of AI into robotic surgery holds the potential to revolutionize the field, extending the application of minimally invasive procedures.
Expanding Applications:
Robotic surgery has already established its presence in various medical specialties, from neurosurgery and urology to gynecology, gastrointestinal surgery, general surgery, and cardiac procedures. With technological advancements, the scope of robotic surgery is anticipated to broaden further, encompassing an even wider range of surgical procedures and specialties. This expansion into new areas promises enhanced precision, control, and accuracy in procedures that were once confined to traditional surgical techniques, heralding increased benefits for both patients and healthcare providers.
Single Port Advancements:
Single-port robotic surgery, rooted in single incision laparoscopic surgery (SILS), has evolved since its introduction in 2008 with the Da Vinci SP surgical system. Utilizing a small incision for intra-body procedures, this approach has expanded to cover various surgeries, including cholecystectomy, appendectomy, colectomy, nephrectomy, hysterectomy, myomectomy, gastric bypass, sleeve gastrectomy, and transoral robotic surgery. Advantages include enhanced instrument control, triangulation for 3D visualization, and ergonomic benefits for surgeons. Patients benefit from faster access to anatomy, reduced trauma, improved cosmetic outcomes, and shorter recovery times. Despite these advantages, challenges such as the cost of implementation, training time, and proving distinct patient benefits persist. As technology evolves, addressing these challenges becomes crucial to realizing the full potential of single-port robotic surgery.
