Clinical applications of robotic surgery
Surgical robots integrate mechanical engineering, computer science, and medical imaging technologies. Equipped with high-definition three-dimensional visualization systems and highly flexible robotic arms, they assist physicians in performing precise, minimally invasive procedures-such as positioning, cutting, hemostasis, and suturing-within confined anatomical spaces. These capabilities significantly reduce surgical risks while also alleviating physician fatigue.
Surgical robots are primarily applied in urology, general surgery, gynecology, orthopedics, and pan-vascular interventions, offering enhanced precision, reduced tissue trauma, and faster patient recovery.
Key application areas include:
1. Laparoscopic Surgical Robots (e.g., the da Vinci system): The most widely adopted category, used in complex minimally invasive procedures such as urologic surgeries (e.g., radical prostatectomy), general surgery (including liver, gallbladder, and colorectal procedures), thoracic surgery, and gynecology.
2. Orthopedic Surgical Robots: Employed in procedures such as spinal pedicle screw placement and joint replacement, enabling more accurate positioning and reduced intraoperative radiation exposure.
3. Pan-Vascular Interventional Surgical Robots: Mainly used in endovascular treatments for cardiovascular, cerebrovascular, and other vascular diseases.
Natural Orifice Surgical Robots: Applied in areas such as respiratory medicine, enabling early lung cancer diagnosis and needle biopsy procedures via natural orifices, including the bronchial pathway.
4. Percutaneous Puncture Surgical Robots: Designed for high-precision biopsy sampling of organs such as the lung, breast, and prostate, as well as for assisting in minimally invasive stone removal procedures.
The key advantages of surgical robots include overcoming the physical limitations of the human hand, enabling multi-degree (up to 540-degree) instrument articulation, providing high-definition visualization, supporting remote surgical operations, and reducing the risk of infection.
