01 The Evolution of Surgical Robotics
I. Germination and Early Exploration (1980s to early 1990s)
1985: A physician at Los Angeles Hospital performed the world's first robot-assisted neurosurgical biopsy using the industrial robot PUMA 560, marking the inaugural application of robotic technology in surgical practice.
1988: The PROBOT system successfully completed the first robot-assisted prostate surgery, further demonstrating robotic potential in surgical interventions.
II. Rapid Development and Commercialization (1990s to early 2000s)
1992: The ROBODOC surgical system developed by Integrated Surgical Systems debuted, performing total hip replacement surgery and receiving U.S. Food and Drug Administration (FDA) approval — the first clinically authorized robotic surgical system.
1997: Intuitive Surgical's da Vinci Surgical System completed its first human trials. Incorporating master-slave teleoperation technology and high-definition binocular imaging, it established an intuitive hand-eye coordination loop that significantly enhanced surgical precision and flexibility.
1999: The FDA-approved da Vinci System began global commercialization, heralding the era of surgical robot commercialization.
III. Diversification and Specialization (Early 2000s to Present)
Post-2000: With technological maturation and market expansion, surgical robots found applications across multiple specialties including orthopedics, neurosurgery, urology, and gynecology. Leading manufacturers introduced specialized systems such as Stryker's Mako Orthopedic Robot and Johnson & Johnson's Monarch Platform, driving sector-specific innovation.
02 Classification of Surgical Robots
- Laparoscopic Surgical Robots
- rthopedic Surgical Robots
- Pan-Vascular Intervention Robots
- Natural Orifice Robotic Systems
- Percutaneous Puncture Robots
Surgical Robotics Classification
| Surgical Field | Primary Function |
|---|---|
| Laparoscopic Surgical Robots | Perform diverse procedures (e.g., urology, gynecology, thoracic, general surgery). Laparoscopes extend surgeons' visual access to internal cavities, while robotic arms mimic hand movements to manipulate scopes and instruments. |
| Orthopedic Surgical Robots | Assist joint replacements and spinal surgeries. Provide enhanced surgical site imaging, minimize damage to healthy bone tissue, and accelerate patient recovery. |
| Pan-Vascular Intervention Robots | Treat diseases of cardiac, cerebral, or vascular systems. |
| Natural Orifice Robotic Systems | Deliver instruments through natural body openings (e.g., mouth, anus) for diagnostic/therapeutic procedures in organs like lungs, intestines, and stomach. |
| Percutaneous Puncture Robots | Execute needle-based procedures for tissue sampling (e.g., early detection of lung/breast/prostate cancers) and therapeutic interventions like percutaneous nephrolithotomy to remove kidney stones through small incisions. |
Laparoscopic Surgical Robots
As the largest submarket in surgical robotics, laparoscopic systems enable complex minimally invasive procedures. A typical configuration comprises:
- Surgeon console: Provides 3D visualization and control interface
- Patient-side cart: Equipped with robotic arms holding laparoscopes and micro-surgical instruments
- Imaging system: Delivers real-time internal visualization
The laparoscope transmits real-time internal visuals to surgeons, while robotic arms precisely replicate operator hand movements through master-slave manipulation.
Clinical Applications
Widely adopted in:
- Urology (e.g., prostatectomies)
- Gynecology (e.g., hysterectomies)
- Thoracic surgery
- General abdominal procedures
System Evolution
- Four-Arm Configuration
- Features: 1 endoscope arm + 3 instrument arms
- Access: Requires four small incisions
- Example: da Vinci Xi System
- Single-Port Innovation
- Features: All instruments deployed through single 25-40mm incision
- Advantages:
- Reduced tissue trauma
- Enhanced postoperative recovery
- Improved cosmetic outcomes
- Example: da Vinci SP Platform
Technical Comparison
| Parameter | Four-Arm System | Single-Port System |
|---|---|---|
| Incisions | 4 (8-12mm each) | 1 (25-40mm) |
| Instrument Freedom | Multi-directional | Articulated motion |
| Learning Curve | 20-30 cases | 35-50 cases |
| Target Procedures | Complex resections | Confined-space operations |
This translation maintains:
- Terminology alignment with previous medical robotics documentation
