In the field of minimally invasive surgery, clear, precise, and real-time visual imaging is the cornerstone of surgical success and patient safety. The emergence of 4K endoscopic camera systems aims to provide full HD and even ultra-HD real-time video for complex surgeries such as laparoscopy, arthroscopy, urology, and gynecology, serving as the "super vision eyes" of surgeons. The core performance of this system highly relies on the imaging resolution, color reproduction capability, field of view control, and illumination effect of the front-end optical module. SincereFull's integrated endoscope camera module, with its high resolution, large target surface sensor, integrated high-uniformity LED illumination, and compact industrial design, precisely meets the stringent requirements of 4K surgical systems for image quality and reliability, becoming the key visual core for building professional-grade HD minimally invasive surgical platforms.
4K surgical systems not only require images to be "visible" but also "clearly visible" — capable of distinguishing fine blood vessels, nerve bundles, and tissue layers. This places unprecedentedly high demands on the basic resolution and signal-to-noise ratio of imaging modules. Traditional low-resolution modules are difficult to meet the needs of modern precision surgery for displaying anatomical details.
This module adopts the GC5035 sensor, achieving 5-megapixel (5MP) high-definition still image capture capability. This resolution level surpasses the traditional 1080p full HD standard, providing sufficient pixel foundation and detail reserves for the system to achieve 4K (approximately 8.3-megapixel) ultra-HD dynamic video output or high-resolution still image recording. A high pixel count means that within the same field of view, the image can contain more tissue texture and structural information, helping surgeons identify smaller lesions and anatomical variations on the screen, and providing irreplaceable visual guarantee for refined surgical operations.
Minimally invasive surgery is performed in body cavities or joint cavities, where the surgical field is limited and the structure is complex. The endoscope module needs to provide an appropriate field of view (FOV) to cover a sufficient observation range, and at the same time must have an appropriate depth of field to ensure clear imaging from the nearby instrument tip to the distant tissue plane, avoiding frequent focusing during operations.
The module features a wide field of view of 82° (diagonal), which can provide a broad observation range within the limited operation channel, reduce lens blind spots, and help doctors quickly establish an overall anatomical orientation. Meanwhile, its depth of field is designed to range from 30mm to 80mm. This optimized depth of field range perfectly covers the distance from the front end of the endoscope to the typical surgical operation plane, ensuring that during most laparoscopic or arthroscopic operations, both the instrument movements close to the lens and the state of distant target tissues can remain clear continuously, providing stable visual support for a smooth and uninterrupted surgical process.
Stable lighting is the prerequisite for accurate color reproduction and image uniformity. Inside the body cavity, there is a complete lack of ambient light, and the tissue has complex light absorption and reflection characteristics. Although external fiber cold light sources have high brightness, they may have problems such as uneven illumination, color drift, or high system integration complexity.
This module innovatively integrates 6 high-brightness white LED beads, arranged around the lens to form an integrated lighting system. This design can provide instant illumination without external light sources, simplifying system connections. More importantly, the surrounding layout helps produce uniform, soft, and shadow-free surgical field illumination, effectively reducing local overexposure or dark areas caused by uneven lighting, and ensuring consistent brightness across the entire image. Stable color temperature output provides a basis for truly restoring the natural color of tissues (such as distinguishing ischemic tissue from healthy tissue), making diagnostic judgments based on images more accurate and reliable.
Surgical equipment needs to operate stably for a long time in the tense operating room environment, and its design must be easy to integrate precisely and reliably with the endoscope body and camera host. The physical size, heat dissipation, and stability of the electrical interface of the module are crucial.
The module adopts an integrated compact design with a diameter of Φ7.0mm, which is compatible with a variety of standard endoscope working channels or connection ports, facilitating integration into various rigid endoscopes or sheaths. Its structure is sturdy, suitable for maintaining performance in sterilized and reusable environments. At the electrical level, it adopts a stable 5V power supply (GND, D+, 5V) and independent 3.3V LED drive (ED3.3V, LED+) design. This separated power supply scheme is conducive to precise control of illumination brightness and reduction of interference between circuits, ensuring that both image signals and the lighting system can maintain high stability during long-term continuous surgeries, meeting the ultimate requirements of medical equipment for reliability, safety, and durability.
SincereFull's integrated 5MP endoscope camera module provides a powerful and core visual engine for the new generation of 4K endoscopic surgical systems through its high resolution supporting 4K details, wide field of view and depth of field adapted to endoscopic surgery, integrated uniform illumination ensuring true colors, and compact and reliable design meeting medical-grade integration. Its in-depth integration will directly improve the clarity, authenticity, and stability of surgical images, empowering surgeons to perform more precise and safe minimally invasive operations, thereby promoting the upgrade of minimally invasive surgical visual technology from "visible" to "clearly visible and distinguishable", and ultimately benefiting the majority of patients and improving the overall level of diagnosis and treatment.
