As a pioneer in fiber laser technology for more than ten years, GW Guanghui Laser has always placed clinical needs at the core of innovation. We have launched a new generation with profound accumulation and forward-looking visionAir cooled quasi continuous fiber laser (70W)——This is a cutting-edge device that combines revolutionary air cooling technology, extraordinary compact size, and outstanding peak power (700W), specially designed to improve the efficiency and safety of urological and prostate hyperplasia (BPH) treatment and lithotripsy surgery.

Core technical principles

This product adopts thulium doped fiber laser technology, using a special fiber doped with rare earth element thulium (Tm) as the gain medium. It generates1940nm laser wavelengthHaving unique advantages:This wavelength is very close to the strong absorption peak of water molecules in the near-infrared band.This means that laser energy can be efficiently absorbed by water in biological tissues, instantly converted into thermal energy, thereby achieving precise and efficient tissue vaporization ablation and stone fragmentation. This is the physical basis for this technology to become an ideal choice for minimally invasive urological surgeries such as prostate hyperplasia treatment and laser lithotripsy.

Fearless of space limitations, enjoy high efficiency and stability in tranquility

Disruptive air cooling design:Completely bid farewell to the bulky and cumbersome water cooling system and complex pipelines. GW laser only requires air to achieve efficient heat dissipation, with flexible installation and deployment, greatly saving valuable operating room space. Zero water cooling maintenance burden significantly reduces the long-term operating costs of hospitals and simplifies equipment management.

Extraordinary compact volume:Realize the equipment miniaturization revolution with excellent engineering aesthetics. The lightweight body can be easily integrated into various operating tables or mobile platforms, improving the utilization of operating room space and workflow efficiency, creating a more free and focused operating environment for medical staff.

Peak power surging, precise and calm surgery

70W high average power, 700W super peak power: providing abundant and stable energy guarantee for tissue vaporization, cutting, and stone crushing. When treating benign prostatic tissue, the vaporization efficiency is significantly improved and the surgical time is effectively shortened; Faced with hard stones, a peak power of 700W ensures fast and thorough crushing, reducing intraoperative repetitive operations.

Wide tuning, effortless:

Precision pulse width regulation (0.02ms -100ms): finely control the interaction time between laser and tissue. Extremely short pulse width (0.02ms) achieves precise cutting and effective hemostasis, reducing thermal damage; A longer pulse width provides efficient vaporization and deep fragmentation energy. The pulse energy can be adjusted from 0.008J to 30J, and doctors can optimize parameters in real-time based on different tissue characteristics (hyperplastic glands, stone composition) and surgical steps (vaporization, cutting, powder fragmentation) to achieve truly personalized surgery.

Up to 5kHz frequency: ensuring fast, continuous, and uniform laser action, improving overall surgical efficiency and smoothness.

Focusing on urology, empowering precise minimally invasive procedures

Laser lithotripsy:700W peak power is a powerful tool for crushing hard stones. Wide range pulse width adjustment allows doctors to flexibly choose, combined with high frequency, greatly improving stone fragmentation efficiency, shortening surgical time, and reducing the potential impact of laser thermal energy on surrounding tissues.

GW Guanghui Laser's new generation 70W air-cooled quasi continuous fiber laser is not just a breakthrough in parameters. We have accumulated ten years of profound technical expertise, deeply insight into clinical pain points, and perfectly integrate surging power, extreme flexibility, and intelligent controllability. It represents our relentless pursuit of "precision medicine" - committed to providing urologists with more powerful, convenient, and reliable surgical tools.
