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, low‑distortion, waterproof 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, distortion control, protective rating, and plug‑and‑play capability 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:
Miniature diameter: Must run parallel to or surround the fiber, with diameter ≤8mm, to pass through introducer sheaths or working channels.
High resolution: Must clearly show the intima, laser‑induced carbonization marks, and any risk of perforation; 1080P is sufficient for clinical needs.
Ultra‑low distortion (<1%): Ensures accurate judgment of the distance and angle between the fiber tip and tissue; distorted images lead to misjudgment.
Fixed focus (30‑50mm): Typical working distance; focus‑free simplifies operation.
IP67 waterproof: Withstands blood, irrigation fluid, and disinfection soaking.
Plug‑and‑play: USB connection to a medical monitor or computer; UVC driver‑free reduces integration complexity.
Based on our understanding of medical endoscopes and interventional instruments, a Mini Camera Module truly suited for working alongside a laser probe achieves precise alignment across diameter, imaging, distortion, focus, 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. An 8mm camera module is suitable for direct placement alongside the fiber or through a multi‑lumen catheter for open surgery or superficial cosmetic laser guidance. The steel sheath is robust, resisting minor collisions and irrigation pressure.
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 1080P Camera Module features a 2MP CMOS sensor, outputting 1920×1080 (1080P) Full HD resolution. At the working distance of 30‑50mm, 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 an F2.8 large aperture, it delivers bright images even in the presence of blood or irrigation fluid.
Laser ablation requires the fiber to be slowly retracted parallel to the vessel wall while keeping the tip centered in the lumen. If the camera image has distortion (e.g., barrel distortion), the true position of the vessel wall is warped, leading the physician to misjudge the fiber‑to‑wall distance. This module controls distortion below 1% with a 60° FOV, maintaining true geometric relationships across the entire field. This is critical for:
Ensuring uniform laser energy delivery to the vessel wall
Avoiding vessel perforation that could cause hematoma or nerve damage
Guiding the fiber retraction speed
During endovenous laser procedures, the camera‑to‑tissue distance is relatively stable at 30‑50mm. A Fixed Focus design eliminates any focusing operation, reducing probe complexity and avoiding missed critical frames due to focus delays. With sufficient depth of field, the image remains sharp even if the fiber wiggles slightly.
During surgery, the camera contacts blood, saline, iodine, etc. After use, it must be thoroughly cleaned and disinfected. This module is IP67 waterproof, tolerating immersion at 1 meter for 30 minutes. The steel sheath prevents mechanical damage, and the smooth surface resists protein adhesion, making cleaning easy.
In operating rooms or clinics, physicians can view the image on a laptop, tablet, or even a phone. This module uses a USB interface (Type‑A or Type‑C) with built‑in UVC driver‑free protocol. Plug‑and‑play, no driver installation; simply connect to any mainstream OS device and the live view appears. Together with the laser generator, it enables “fire‑and‑watch” operation.
1. Endovenous Laser Ablation of Lower‑Limb Varicose Veins: Place the 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.
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 an 8mm diameter, 1080P HD, <1% ultra‑low distortion, 30‑50mm fixed focus, IP67 waterproof, USB driver‑free miniature 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.
