Working Principle of Robot-Assisted Orthopedic Surgery Systems: Synergy of Three Core Modules

 The rapid development of medical technology and artificial intelligence has given rise to the robot-assisted orthopedic surgery system, which is reshaping the way surgeons approach complex orthopedic procedures. Unlike traditional techniques that rely heavily on manual precision, this advanced system integrates robotics, imaging, and intelligent software to deliver consistent, accurate, and minimally invasive surgical outcomes. At the heart of this innovation lies the synergy of three interdependent modules: the robotic arm system, the imaging navigation system, and the master control system. Together, they create a closed-loop surgical process that enhances both safety and efficiency.

Core Modules of a Robot-Assisted Orthopedic Surgery System

1. Robotic Arm System (Execution Unit)

The robotic arm serves as the “execution hand” of the system. Its design is focused on reproducing and even surpassing the dexterity of a human surgeon.

  • Multi-degree-of-freedom motion: Typically designed with 6–7 degrees of freedom, the arm can maneuver in confined spaces with exceptional flexibility.
  • Sub-millimeter accuracy: High-precision servo motors and reducers (harmonic or RV) ensure accuracy ≤1 mm, which is critical in delicate bone drilling or implant placement.
  • Force feedback technology: Advanced models incorporate real-time resistance monitoring to prevent excessive force and safeguard surrounding tissues.

2. Imaging Navigation System (Perception Unit)

The imaging navigation system provides the “eyes” of the robot, ensuring each movement aligns with the surgical plan.

  • Preoperative 3D modeling: Using CT or intraoperative scans, detailed bone structures are reconstructed digitally.
  • 3D C-arm navigation in orthopedic robotics: Real-time guidance through intraoperative imaging enables surgeons to validate and adjust trajectories instantly, reducing errors.
  • Optical and electromagnetic tracking: Patient posture, robotic arm position, and tool orientation are tracked continuously, maintaining alignment with the surgical pathway.
  • Image fusion capability: By merging preoperative data with intraoperative feedback, surgeons gain a comprehensive visual guide throughout the operation.

3. Master Control System (Decision-Making Unit)

Acting as the “brain,” the master control system ensures smooth collaboration between human and machine.

  • Preoperative planning software: Surgeons simulate screw placement, osteotomy angles, or implant positioning on virtual 3D models, with the system generating precise robotic arm trajectories.
  • Real-time monitoring and error alerts: During surgery, the interface displays anatomical references and issues immediate warnings if deviations occur.
  • Interactive operation: The surgeon remains in command through console input, voice commands, or footswitches, ensuring human oversight in every step.

Advantages of Robot-Assisted Orthopedic Surgery

Compared with conventional orthopedic methods, the robot-assisted orthopedic surgery system offers several distinct advantages:

  1. Higher surgical accuracy: Sub-millimeter precision reduces the likelihood of screw misplacement.
  2. Minimally invasive techniques: Smaller incisions mean less blood loss and faster recovery.
  3. Reduced radiation exposure: With the support of 3D C-arm navigation in orthopedic robotics, fewer intraoperative scans are needed.
  4. Consistency and reproducibility: The system standardizes procedures, lowering the dependence on individual surgeon experience.

Clinical Application Example

A notable case is the Perlove Medical PL300B system, which integrates seamlessly with the PLX C7600 3D C-arm. This unified “same-platform solution” applies advanced trajectory registration technology for automatic alignment and real-time imaging guidance. The result is not only a smoother surgical workflow but also an impressive precision level of ≤0.7 mm. Such systems demonstrate how robot-assisted orthopedic surgery systems are transforming orthopedic care into a more predictable, safer, and patient-centered process.

Conclusion

The robot-assisted orthopedic surgery system represents a significant leap forward in surgical innovation. By combining robotic arms, intelligent imaging, and advanced control systems, it offers a new paradigm of safety, accuracy, and efficiency in orthopedic surgery. With continuous advancements—especially the adoption of 3D C-arm navigation in orthopedic robotics—these systems will play an increasingly central role in the operating rooms of the future.

CPAP continuous positive airway pressure  (Continuous Positive Airway Pressure), namely with the mask will continuous positive pressure airflow into the airway. Use this way to oxygen machine called CPAP ventilator. So, what is the working principle of CPAP respirator? (perlong medical -- S9600 ventilator) In daily life, when we breathe, intrapulmonary pressure below the atmospheric pressure, air can enter lung, when the two kinds of pressure balance, the suction stop; exhale, intrapulmonary pressure higher than the atmospheric pressure, breath, when intrapulmonary pressure increased continuously, and is equal to atmospheric pressure, breath stop. Application of continuous positive airway pressure, breathe in, there is a pressure to push air into the lungs, expiratory when also the existence of an additional pressure, prevent gas exhaled. The additional pressure on the inspiratory and expiratory all play a role, but no size change, it is called a continuous positive airway p...
