In endovenous laser ablation (EVLA) and aesthetic laser procedures, the physician must deliver the laser fiber precisely to the target tissue while monitoring the operative area in real time to avoid thermal injury and ensure uniform energy distribution. High‑quality laser fibers, such as the Fibernex® series with SMA‑905 compatibility, 800‑1600nm wavelength coverage, multiple core diameters, and single‑use/reusable options, provide reliable tools for clinical treatment. However, the success of laser surgery depends not only on the fiber itself but also on intraoperative visual guidance—especially when the access path is complex and precise positioning is critical.
If a miniature, high‑definition, ultra‑wide‑angle, waterproof, plug‑and‑play endoscope camera module is integrated with the laser probe, the physician can see the tip position, surrounding tissue status, and laser effect on a display in real time, greatly improving safety and precision. The camera module’s diameter, resolution, field of view, waterproof rating, and interface compatibility directly determine whether visual guidance can stably and clearly present key details within narrow surgical cavities.
Unlike conventional endoscopes, an auxiliary camera integrated with a laser probe must meet the following requirements:
Extreme Miniaturization: Must run parallel to the fiber, with diameter ≤3.0mm, to pass through introducer sheaths or working channels.
High‑Definition Imaging: Must clearly show the intima, laser‑induced carbonization marks, and any risk of perforation; 1MP (720P) is sufficient for clinical needs.
Ultra‑Wide Field of View: Covers a larger area within a narrow cavity, reducing probe movement and blind spots.
Fixed Focus (5‑50mm): Typical working distance; focus‑free simplifies operation.
IP67 Waterproof: Withstands blood, irrigation fluid, and disinfection soaking.
Plug‑and‑Play: Type‑C connection to medical monitors or computers; UVC driver‑free reduces integration complexity.
Based on our understanding of medical endoscopes and interventional instruments, a Separate Endoscope module truly suited for working alongside a laser probe achieves precise alignment across diameter, imaging, field of view, protection, and interface.
EVLA is typically performed through a 5‑7F introducer sheath (outer diameter ≈1.7‑2.3mm). Integrating a camera requires more space. For larger laser fibers (e.g., 600μm core diameter), thin‑wall fiber (2.25mm outer diameter) options exist. A 3.0mm Diameter camera module with a Steel Sheel (steel sheath) can be placed parallel to the fiber or through a multi‑lumen catheter for open surgery or superficial cosmetic laser guidance. The steel sheath resists minor collisions and irrigation pressure. IP67 Waterproof makes it fully sealed, tolerating immersion at 1 meter for 30 minutes, resisting blood and irrigants. Post‑operative cleaning and disinfection are also easier.
During laser ablation, the physician needs to observe: whether the fiber tip is aligned with the vein intima, whether the laser produces the expected carbonization, and whether there is excessive thermal damage. Blurry images delay judgment and increase complication risk.
This 720P Camera Module (also an HD Camera Module) features a 1MP CMOS sensor, outputting 1280×720 (720P) HD resolution at 30fps. At the working distance of 5‑50mm, it clearly shows:
Color changes of the vein intima (pink→white→brown)
Tiny smoke plumes and carbonized crust from laser action
Any active bleeding points or signs of impending perforation
Distance between the fiber tip and the vessel wall
With separate LED fill lights, it delivers bright images even in the presence of blood or irrigation fluid.
In narrow vessels or body cavities, an ultra‑wide angle covers more wall area without moving the probe, reducing missed detections. This module features a 121.5° diagonal ultra‑wide angle (97.2° horizontal × 73° vertical), with distortion controlled within -30% (acceptable for such a wide angle). Advantages:
At 10mm distance, covers about 25‑30mm laterally, showing more than half the vessel circumference.
Helps judge whether the fiber is centered in the lumen, avoiding eccentric burns.
Complements path‑recording features to build a more complete intracavity map.
During laser procedures, the camera‑to‑tissue distance is relatively stable at 5‑50mm. A fixed‑focus design eliminates any focusing operation, reducing probe complexity and avoiding missed critical frames due to focus delays. With an F5.5 aperture and sufficient depth of field, the image remains sharp even if the fiber wiggles slightly.
In operating rooms or clinics, physicians can view the image on a laptop, tablet, or even a Type‑C phone. This module uses a Type‑C interface with built‑in UVC Camera Module driver‑free protocol, supporting USB Camera Module plug‑and‑play. Advantages:
Reversible plug: Type‑C simplifies connection, no orientation worry.
Plug‑and‑play: Connects to any mainstream OS device (Windows, macOS, Android) without driver installation.
Low latency: 720P@30fps real‑time transmission ensures sync between instrument manipulation and画面.
Separate LED layout: Provides uniform illumination, reducing glare.
1. Endovenous Laser Ablation of Lower‑Limb Varicose Veins: Place the 3.0mm camera alongside the fiber into the great saphenous vein, monitor the fiber position and intimal reaction in real time, ensuring uniform energy delivery and avoiding saphenous nerve injury. The 121.5° ultra‑wide view observes both anterior and posterior walls, improving safety.
2. Cutaneous Cosmetic Laser Therapy: For pigmentation, tattoo removal, or hair‑removal lasers, the camera captures the treatment area, helping the physician adjust spot position and overlap to avoid burns or missed areas.
3. Interstitial Laser Thermal Therapy for Tumors: During laser ablation of solid tumors (liver, thyroid), the camera helps confirm fiber insertion depth and observe the vaporization zone and relationship to adjacent large vessels.
4. Teaching & Surgical Recording: Connect the camera feed to a large screen for trainees to observe live; record the procedure for case review and quality control.
The precision and safety of laser surgery depend on real‑time intraoperative visualization. Adding a 3.0mm diameter, 720P HD, 121.5° ultra‑wide angle, IP67 waterproof, Type‑C UVC driver‑free miniature separate endoscope camera module to the Fibernex® laser probe allows the physician to operate as if under a microscope, clearly seeing every interaction between the fiber and tissue. Procedures become faster, complications fewer, and patients recover sooner.
