Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an integrated light-guiding component of an endoscope. Background Art

[0002] The light guide plug of the existing endoscope integrated light guide component is connected to the host through an external electrical cable. The exposed electrical signal line is very susceptible to external electromagnetic interference because the shielding layer is generally 0.5 thick metal mesh to maintain flexibility, and the electromagnetic waves transmitted by the device are also likely to affect other devices. At the same time, the gas path of the existing endoscope integrated light guide component sends gas to the endoscope air pipe through the three-way component at one end of the light guide plug, and sends gas to the water gas bottle at the other end to increase the pressure, so that water flows into the water pipe.

[0003] For example, the Chinese patent: "CN208464028U", the technical solution disclosed in this patent is as follows: an integrated light-guiding component of an endoscope is disclosed, which forms an integrated connector by modifying the electrical connection interface between the light-guiding terminal and the host from an external single wiring to a method in which an electrical connection male end and an electrical connection female end cooperate with each other to realize communication connection with the host, thereby reducing the connection terminals. This not only facilitates the installation of the light-guiding terminal and the host, but also enables all communication lines to be encapsulated in the metal shell of the light-guiding terminal, greatly improving the electromagnetic compatibility performance and reliability, indirectly reducing the requirements for connector reliability and significantly reducing costs; at the same time, the air intake path is changed to make it more airtight and easy to maintain compared to the prior art.

[0004] However, in actual use, the connecting tube cannot be extended or retracted, so it is limited in some usage scenarios and needs to be extended or retracted. Utility Model Content
