A semiconductor laser medical device based on fiber coupling module

Abstract

The present invention provides a semiconductor laser medical device based on an optical fiber coupling module, which is convenient for operation and use, improves treatment efficiency, and is more stable and reliable. The semiconductor laser medical device includes an optical fiber coupling module and a laser medical hand tool; the laser medical hand tool includes a cooling head, a TEC, a circulating water structural member and a back cover that are sequentially fixed in the axial direction, wherein the cooling head is a hollow through structure, An optical waveguide is fixed in the cavity of the cooling head, and the cross-sections of the TEC and the circulating water structural member perpendicular to the axial direction are annular structures so as to leave a laser transmission channel coaxial with the optical waveguide. The pipe wall of the circulating water structural member There is an inner chamber as a water passage; the back cover is provided with an optical fiber interface, a TEC line interface and a circulating water interface communicated with the water passage, and the output optical fiber, TEC power cord and water passage of the optical fiber coupling module The hoses are respectively connected to the corresponding ports on the rear cover.

Description

technical field [0001] The invention relates to a semiconductor laser medical device. Background technique [0002] At present, medical devices based on semiconductor lasers are generally composed of light sources, optical systems, water circulation systems, and refrigeration systems, such as figure 1 shown. Among them, the light source part generally adopts a stack of semiconductor lasers, and is integrated with other parts to be integrated into the product shell. This structure has the following problems: [0003] a) Due to the high level of integration, the handle is too heavy and bulky, which can easily cause sore hands and increase the risk of treatment during long-term treatment; [0004] b) Due to the coexistence of the refrigeration system and the water circulation system with the light source, the risk of using the laser increases (possible factors such as condensation and water leakage will cause the laser to fail); [0005] c) The light spot is uneven and the ...
