Device Story

PenLase is a portable, battery-operated semiconductor diode laser system for oral soft tissue surgery. Device uses AlGaAs semiconductor chips to generate 810±10 nm infrared laser radiation. Laser power (0.7W or 1.7W) is delivered to the treatment site via disposable, bendable fiber tips. Operated by clinicians in a dental or clinical setting; no external cords or foot switches required. Charging station recharges batteries. Laser energy facilitates incision, excision, hemostasis, coagulation, and vaporization of soft tissue. Benefits include improved access via bendable tips and cordless portability for multiple procedures per charge.

- 6. Device Description
PenLase is a surgical equipment, simple tool, portable, and easy to use. It is a tool that can be used for the treatment of oral soft tissue surgery, plastic surgery.

The PenLase utilizes a semiconductor diode which consists of semiconductor "chips" made from Aluminum, Gallium and Arsenide, together commonly referred to as AlGaAs , with invisible infrared radiation as a laser source. The laser power is delivered to the treatment area via a fiber tip. The disposable fiber tips are bendable in a variety of angle for maximum access to all areas of the mouth.

PenLase delivers 0.7 Watts and 1.7 Watts with wavelength 810±10 nm of continue laser power without cords, outlets or foot switches, which makes its battery life last longer.
