Description

Technical Field

[0001] The utility model relates to the technical field of biomedical equipment, in particular to a quick-insertion optical fiber probe. Background Art

[0002] In the medical field and biological detection field, optical fiber is often used as a probe to achieve functions such as tissue cutting, cell ablation, cell analysis, and gene detection. The common feature of the above application scenarios is that the optical fiber probe must directly contact biological tissue or cell solution and is not reusable.

[0003] The main users of these fiber optic probes are medical staff and testing personnel, and quick installation and removal are also important demands. The conventional method is the plug-in coupling of the fiber optic patch cord and the fiber optic probe, and the two are connected through an adapter (flange). One end of the fiber optic patch cord is connected to the laser or light source of the device, and the other end is connected to the connector of the fiber optic probe through an adapter, thereby achieving the function of guiding light and transmitting energy.

[0004] This method has the following main defects: 1. An adapter is required, and the connectors of the fiber optic patch cord and the fiber optic probe must be tightened and fixed by nuts, which is inconvenient for users to install and disassemble; 2. A connector must be made at one end of the fiber optic probe, which is not suitable for mass production and processing. Utility Model Content
