[Design of an integrative laser laryngoscope system]

Laser technology is widely used in many medical fields such as general surgery, cardio-thoracic surgery, neurosurgery and urology. Laser has the characteristics of identical direction and high energy density, so that a laser knife leaves smooth incisions, less hemorrhage and less infection. The design presented in this paper applied the advanced laser technology in laryngoscopic operations, which increases efficiency and safety of the operation. The design included a laryngoscope, a laser-knife system host machine and a laser-knife, which were integrated in the front of the laryngoscope working terminal. Operators could choose the laser with appropriate wavelength to cut, irradiate, stop bleeding and coagulate the foreign objects or lesions of the larynx. A Chinese national patent (patent number ZL201020537693. 5) has been granted to the design.
