Title:
OPTICAL PATH SWITCHING STRUCTURE FOR HANDLE OF ORAL LASER TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/133644
Kind Code:
A1
Abstract:
An optical path switching structure for a handle of an oral laser treatment device, comprising an optical fiber input portion, an optical fiber output portion, and a connector (1). One end of the optical fiber input portion and one end of the optical fiber output portion are connected by the connector (1), and an output end surface (2) of the optical fiber input portion and an input end surface (3) of the optical fiber output portion are disposed opposite to each other and spaced apart in the connector (1), such that the output end surface (2) of the optical fiber input portion and the input end surface (3) of the optical fiber output portion form a free-space coupling structure for transmitting a laser beam. The fee-space coupling structure allows the mechanism of laser conversion to change from a direct optical-fiber abutment to a free-space abutment, so as to avoid physical contact and the impacts caused by frequent insertion and extraction of output optical fibers, thereby preventing damage to end surfaces of the optical fibers, and improving coupling efficiency and use safety.
