Device Story
Medical diode laser systems (GaAlAs diode bar) utilize semiconductor technology to generate laser energy at 810nm, 940nm, or 980nm. The device includes a main unit with a color LCD touch screen, power source, and fiber-coupling technology to deliver laser energy via optical fibers. Operated by physicians in clinical settings, the system is activated via a footswitch after parameter selection. The laser energy is used for soft tissue surgical applications (ablation, coagulation, etc.). The device provides visual feedback via the LCD and requires the use of protective safety goggles. By enabling precise tissue interaction, the device facilitates surgical procedures, potentially reducing patient trauma and recovery time compared to traditional methods.
Clinical Evidence
Bench testing only. Compliance with IEC 60601-1, IEC 60601-2-22, IEC 60601-1-2, IEC 60825-1, and ISO 10993 (biocompatibility) standards was demonstrated. Software verification was performed per FDA guidance.

Medical diode laser systems are a kind of laser with semiconductor as working material. It consists of working material, cavity resonator and power source.
The medical diode laser systems for this unit is GaAlAs diode bar, and the wavelength are 810mm/980mm of GBOX-15A/15B, 810/980mm of VELAS II -30A/30B, 810/980/940nm of
{5}------------------------------------------------
VELAS II -60A/60B/60C. It features impact structure, high efficiency and long lifetime. The beam divergence angle is too large lead to poor beam quality. In order to better meet the needs of Laser Diode practical applications, Laser Diode carried beam shaping is very necessary. With the GIGAA'S unique fiber-coupling technology, the laser beam can be coupled efficiently into the fiber.
To start the laser unit, turn the main switch ON into " | " position. Immediately the power indicator will be green with the system fans working. At the same time, the LCD screen lights up as the picture shows below.
After finishing setting the parameters, press the "Ready" button and then the system will remind you to wear the safety goggles (protect wavelength from 800nm to 1100nm). At this time when you press down the footswitch, the laser will emit.

#### 8. Substantial Equivalence:
The proposed devices of GBOX-15A, GBOX-15B have the same classification information, same indications and intended use, same design principle, similar product design and specifications, same performance effectiveness, performance safety as the predicate device. The differences only exist in The differences only exist in such contents: component of handpiece that do not influence use even if without it, wave rang of wavelength, output power, pulse width, and aiming beam that all can be controlled in range of application. These differences are slight and do not influence the effectiveness and safety of the device. According to the non-clinical test results, the proposed devices are as safe, as effective and perform as well as the predicate device. So the proposed devices are Substantially Equivalent (SE) to the predicate device which is US legally market device.
