Description

Technical Field

[0001] The invention relates to the technical field of laser treatment hand tools, and in particular to a reflective laser microsurgery adapter. Background Art

[0002] The microscope adapter is a set of precision optical systems that can zoom, focus, and precisely universally displace the carbon dioxide laser emitted by the treatment machine (controlled by the operator), and then guide it into the patient's lesion site (such as using a laryngeal support frame to allow the laser to reach the throat through the mouth) for surgery. The operator can adjust the laser beam spot size according to the needs of the lesion by adjusting the beam focusing system of the laser surgery adapter, and then control the movement of the laser beam by controlling the beam movement handle of the laser surgery adapter, thereby accurately completing the surgical treatment process under direct vision of the microscope.
