In robotic surgery, teamwork is a key factor determining success. The primary surgeon operates the robotic arms from the console, while the bedside assistant performs abdominal positioning, trocar placement, instrument insertion angle adjustment, and seamless coordination with the surgeon. However, team training on an actual robotic console is nearly impossible—due to high costs, operating room occupancy, and the inability to simulate various emergency scenarios.
The VirtaMed RoboS simulator solves this problem. It is the first solution that enables true robotic surgery team training by integrating the fully sensorized abdomen of the LaparoS laparoscopic trainer with the RoboS system. The bedside assistant can practice real-world skills such as abdominal positioning, trocar placement, instrument insertion angles, and seamless coordination with the surgeon. This enhances operating room team performance, making robotic surgery safer and more effective.
In such a high-fidelity simulator, the vision system plays a critical role. Especially for visualizing instrument manipulation inside the simulated abdomen, trocar placement angles, and tissue contact details, a camera module capable of entering tiny cavities, offering ultra-wide field of view and macro imaging, is essential. The camera module’s diameter, field of view, macro clarity, waterproofing, and interface compatibility directly determine the simulator’s training realism and teaching effectiveness.
Unlike standard laparoscopic cameras, a micro camera embedded inside the simulator for teaching observation must meet the following requirements:
Extreme Miniaturization: Must fit into narrow channels of the simulated abdomen (trocar ports, instrument entry points) without interfering with trainees. Diameter under 1mm is required.
Ultra-Wide Field of View: Covers multiple instruments, working areas, and tissue models in a tight space, reducing blind spots.
Macro Precision Imaging: Must clearly show instrument tip-tissue contact, suture passage through tissue, at working distances of 3-30mm.
Waterproof and Anti-Fog: The simulated abdomen may contain fluids or lubricants; the camera must resist moisture.
Plug-and-Play: Quick integration with the simulator’s main computer (PC or embedded platform); UVC driver-free simplifies development.
Based on our understanding of medical simulation and precision imaging applications, an embedded 1/31 inch camera module truly suited for a robotic surgery simulator achieves precise alignment across sensor, size, FOV, optics, interface, and protection.
The VirtaMed RoboS simulator’s abdominal model includes multiple trocar ports, instrument channels, and anatomical landmarks. Conventional cameras are too large, blocking trainees’ view or interfering with instrument movement. This camera module’s probe diameter of only 0.95±0.05mm can be easily placed inside trocars, near instrument tips, or even between tissue layers, recording the assistant‘s operations from a “first-person” perspective.
This Mini Camera Module features the OCHTA10 CMOS sensor with a probe diameter of 0.95±0.05mm and a waterproof steel shell (optional IP67). Key advantages:
0.95mm ultra-fine probe: Passes through 1mm-diameter ports, fits inside instrument working channels, capturing real-time images of grasper jaw opening/closing and needle penetration without disturbing trainees.
Separate structure: Probe separates from the main unit, reducing internal load and facilitating integration onto robot arms or fixed mounts.
IP67 protection: Resists moisture inside the simulated abdomen and withstands cleaning/disinfection.
For surgery simulators, 0.95mm means “invisible yet present”—trainees barely notice the camera, yet obtain an extremely realistic operational view.
Inside the simulated abdomen, the assistant needs to simultaneously observe multiple instruments, trocar positions, and tissue reactions. Standard laparoscopic cameras have narrow FOVs (60-90°), requiring frequent lens movement. The 127° ultra-wide angle, combined with 3-30mm macro focusing, covers the entire working triangle in a single frame at close range.
This Wide Angle Camera Module features a 127° diagonal (100°H×100°V) ultra-wide angle paired with a 3-30mm macro-specific optical design. Advantages:
127° ultra-wide angle: At 10mm working distance, simultaneously captures two instrument tips, the port opening, and surrounding tissue. Trainees get a global view without moving the camera.
3-30mm macro: Optimized for close-up operations. At 5mm, clearly shows fine tissue deformation during grasper use and suture tension changes.
0.175mm focal length + F2.8 aperture: Ensures sufficient light intake at extremely short focal lengths, with distortion control (< -11%) for true imaging.
For teaching assessment, instructors can analyze frame-by-frame replay of instrument angles, depth, and coordination.
The simulated abdomen is often dimly lit to mimic real surgery. The camera needs built-in illumination without excessive glare.
The module offers optional Micro USB 5P/Type-C dual interfaces with independent LED control. Users adjust brightness for different simulated tissues (dark organs, clear fluids) to achieve uniform, glare-free images. Combined with the OCHTA10 sensor‘s low-light sensitivity (0.16MP resolution), clear images are deliverable even in simulated blood or murky fluids.
Surgery simulator software typically runs on Windows or Linux. The camera must be plug-and-play to reduce development costs.
This USB Camera Module uses a standard USB 2.0 interface and supports the UVC driver-free protocol. Advantages:
Plug-and-play: Automatically recognized when connected to the simulator host, no custom driver development, significantly shortening time-to-market.
Wide platform compatibility: Supports Windows, Linux, Android, macOS, adapting to various simulator architectures.
USB power: Single cable handles both power and data, simplifying internal cabling.
For simulator manufacturers, UVC means “as easy as a peripheral”—cameras can be swapped or upgraded without affecting core software.
Simulators endure thousands of operations. The camera must resist wear, disinfection, and minor impacts. The stainless steel shell and IP67 rating ensure reliability under frequent wiping and disinfection. The ultra-fine probe and lightweight design add minimal load, preserving mechanical precision.
1. Bedside Assistant Skill Training: The 0.95mm camera is placed inside a trocar or instrument channel, recording trocar placement, instrument insertion, and angle adjustment. Instructors review playback to analyze procedural correctness.
2. Surgeon-Assistant Coordination Training: Cameras are placed at the console and assistant areas, recording team coordination from multiple angles. The 127° wide angle captures multiple instruments simultaneously, evaluating coordination.
3. Instrument Manipulation Accuracy Assessment: At 3-30mm macro, clearly shows instrument-tissue interaction, such as suture depth, knot tension, and electrosurgical hook trajectory, enabling quantitative scoring.
4. Standardized Surgical Workflow Teaching: Camera footage is recorded synchronously with simulator software to produce standardized teaching videos for repeated trainee study.
The core value of the VirtaMed RoboS simulator lies in “enabling true robotic surgery team training.” Adding a camera module with 0.95mm diameter, 127° ultra-wide angle, 3-30mm macro, UVC driver-free elevates the system’s teaching observation capability to unprecedented detail. Trainees see the micro-effects of every action, instructors obtain objective quantitative assessment data, ultimately making robotic surgery safer and more effective.
